USER MANUAL

Buku keterangan ini adalah penjelasan dari Peta Satuan Lahan dan Tanah lembar Toboali (1112), Sumatera, sekala 1:250.000.

This booklet is an explanation of the 1:250,000 scale Land Unit and Soil map of the Toboali mapsheet (1112), Sumatra.

Legenda peta berisikan satuan lahan yang merupakan satuan geomorfik dan dibatasi dengan cara menginterpretasi foto udara, citra satelit dan citra Radar. Isi dari tiap satuan lahan diperiksa di lapangan dan kemudian dicatat. Hanya sebahagian dari semua informasi ini disajikan dalam peta, sedangkan sebahagian lagi diberikan secara ringkas dalam Buku Keterangan ini ; informasi yang lebih lengkap dapat tersedia jika diminta.

The legend of the map consists of Land Units, which are geomorphic units, delineated by interpretation of images such as aerial photographs, satellite imagery and Synthetic Aperture Radar. The contents of each of the units is checked in the field and recorded. Only part of this information can be represented in the map; the remainder is briefly documented in the present explanatory notes, and more complete information is available upon request.

Simbol peta menunjukan grup fisiografi (huruf besar), tipe batuan (huruf kecil), dan pembagian lebih Ianjut berdasarkan atas lereng dan tingkat torehan (pada daerah berlereng dan angkatan) atau berdasarkan lingkungan pengendapan/hidrologinya (pada daerah aluvial resen dan marin), yang ditunjukan oleh angka. Huruf kecil yang berada dimuka kode grup fisiografi menunjukan adanya tutupan dari bahan lain, seperti tutupan abu volkan pada perbukitan dari batuan sedimen atau lapisan bahan organik tipis pada dataran aluvial.

Hap symbols indicate physiographic group (capital letter), rock type (lower case letter), and subdivisions according to slope and dissection (in sloping and uplifted areas) or to sedimentary/hydrological environment (in recent alluvial and marine areas), indicated with numbers. Lower case letters preceding the physiographic group code are used to indicate covers of material with differing composition, such as volcanic ash covers on hills of sedimentary rocks, or thin peat on alluvial plain units.

Grup fisiografi tersebut adalah : Kubah Gambut, Aluvial, Marin, Teras Marin, Dataran Tuf Masam, Dataran, Tuf Masam Toba, Volkan, Karst, Perbukitan, Pegunungan/Plato dan Aneka Bentuk. Grup Dataran Tuf Masam, Tuf Masam Toba, Volkan, Kubah Gambut dan Karst pembagiannya didasarkan pada tipe batuan dan morfologi yang spesifik yang hubungannya erat dengan sifat tanah yang spesifik. Grup yang lainnya sebahagian besar hanya berdasarkan pada morfologi.

The physiographic groups are : Peat Domes, Alluvial, Marine, Marine Terrace, Acid Tuff Plains, Plains, Toba Acid Tuff, Volcanic, Karst, Hill, Mountain/Plateau and Miscellaneous. The Acid Tuff Plain, the Toba Acid Tuff, the Volcanic, the Peat Domes and the Karst group are based on rock type and specific morphology, with a close link to specific soil characterestics. The other groups are largely morphological .

Untuk semua sàtuan lahan, data keadaan tanah dan hubungan tanah dengan bentang alam disajikan pada Uraian Satuan

For all land units, data on soils and soil/landscape relations are presented in the Land Unit Descriptions. These

1. PENDAHULUAN

1. INTRODUCTION

1.1.Latar belakang

1.1.Background

Buku Keterangan dan Peta Satuan Lahan & Tanah ini merupakan sebaglan has il akhir survëi tanah tinjau Sumatra yang dilaksanakan untuk Proyek Perencanaan dan Evaluasi Sumber Daya Lahan dan diprakarsai tahun 1988 oleh Pemerintah Indonesia serta dibiayai oleh Bank Pembangunan Asia. Pelaksanaan survei dilakukan antara bulan Februari dan Maret 1989 oleh Tim Survei Tanah dari Pusat Penelitian Tanah (PPT), sedangkan korelasinya dilakukan pada bulan Januari Februari 1989.

This explanatory booklet and the included maps are part of the final results of the reconnaissance soil survey of Sumatra, which was carried out for the Land Resources Evaluation and Planning Project (LREP), initiated in 1988 by the Goverment of the Republic Indonesia and financed by the Asian Development Bank. The sheet was surveyed between February and March 1989, by teams of the Center for Soil Research (CSR). Hap correlation was carried out in January - February 1989.

1.2.Konsepsi legenda

1.2.Legend concept

Legenda untuk survei ini didasarkan pada pendekatan satuan lahan. Pendekatan ini dlanggap paling sesuai untuk survei ini , sebab pada sekala 1:250.000 dengan intensitas pengamatan lapangan yang kurang, semua batas satuan dapat ditarik dengan cara menginterpretasi citra. Legenda satuan lahan memungkinkan adanya pembatasan setiap satuan dengan sembarang ukuran yang masih dapat dipetakan (tergantung skala peta) dengan memanfaatkan namanama morfologi sederhana dan berulang. Pendekatan ini menunjang Struktur hirarki dan merupakan sistem terbuka sehingga dapat diperbaharui sesuai dengan penerapannya di Indonesia; ia tidak memuat parameter iklim (parameter iklim disimpan dalam data base terpisah dan dapat digabung dengan data base satuan lahan). Tambahan pula legenda satuan lahan erat hubungannya dengan legenda terdahulu di Indonesia mengenai bentuk lahan, sistem lahan dan satuan lahan tanpa k e l i r u penggunaannya (Desaunettes, 1977; RePPProT, 19851988; Kips et al. , 1981) .

The legend for this survey is based on the Land Unit approach. This approach is considered most suitable for this survey, because at a scale of 1:250,000 , with low-density field checks, all unit boundaries are obtained by image interpretation. The land unit legend allows the delineation of mappable units of any size (depending on map scale), it makes use of morphologic'.j. names which are simple and recurrent, it supports an hierarchical structure, it is an open system that can be amended for use anywhere in Indonesia, and it does not contain climatic parameters (the climatic parameters are stored in a separate data base which can be combined with the land unit data base).

Satuan Lahan ini diberi batasan berupa lahan dimana satu atau lebih komponennya mempunyai ciri-ciri khusus dan merupakan satuan lingkungan dengan sembarang ukuran yang dapat dibatasi pada peta. Satuan terkecil yang masih

A Land Unit is defined here as an area of land of which one or more attributes have special characteristics, and it refers to an environmental unit of any size that can be delineated. The smallest unit that can be

Furthermore, the land unit legend is closely related to previous Indonesian land form, land system, and land unit legends (Desaunettes, 1977; RePPProT, 1985-1988; Kips et al., 1981) without being confusing.

dapat d i b a t a s i tanpa menghiraukan sekalanya berukuran 2 mm lebarnya bila bentuk memanjang dan kurang lebih 3 sampai 4 mm bila berbentuk bulat. Pada sekala 1:250.000, suatu satuan yang membulat dengan diagonal 4 mm meliputi kurang lebih 80 ha. Satuan lahan dikelompokkan dalam grup-grup f i s i o g r a f i dan kadangkadang dibagl lagi kedalam sub-grup. Untuk informasi lebih lengkap, lihat pada Buurman et al (1988) dan Balsem et a l . (1989)

delineated on any map, irrespective of scale is about 2 mm wide if it is a linear feature and about 3 to à mm across if it is a circular feature. At a scale of 1:250,000, a circular unit of 4 mm across has a surface of nearly 80 ha. Land units are grouped together in Physiographic Groups and, in some cases, in Sub-Groups. For more detailed informat ion, see Buurman et a l . , (1988) and Balsem et a l . , (1989)

METODOLOGI

METHODOLOGY

2.1.Peta dasar

2.1.Base maps

Peta dasar untuk keperluan pencetakan Peta Satuan Lahan & Tanah disediakan oleh BAKOSURTANAL. Untuk lembar peta ini, peta dasar yang digunakan adalah peta JOINT OPERATIONS GRAPHICS (JOG), Lembar SB48-15, Seri 1501, Edisi 2, Toboali yang dikeluarkan oleh Royal Australian Survey Corps, 1982.

Base maps for the printed Land Unit and Soil map were provided by BAKOSURTANAL. For the present sheet, the base map was the Joint Operations Graphics (JOG), Sheet S348-15, Series 1501, Edition 2, Toboali, published by The Royal Australian Survey Corps 1982.

2.2.Interpretasi citra

2.2.Image interpretation

Survei tinjau ini sebahagian besar didasarkan pada interpretasi citra dan batas-batas satuan sesungguhnya ditarik berdasarkan citra. Macam citra yang digunakan adalah sebagai berlkut:

The surveys are extensively based on image interpretation and virtually all unit boundaries are imagery-based. The following imagery was used:

-potret udara hitam/putih sekala 1:100.000, Angkatan Udara Australia 1976 (umumnya kualitas rendah karena dicetak berulang kali dan pemrosesan yang kurang baik). -LANDSAT komposit warna (band 4-5-6) sekala 1:250.000 tahun 1985 yang diperoleh dari LAPAN (kualitas bervariasi, sekala kurang teliti). -citra Radar stereo STAR-1, 1988 (cetakan hitam putih, kualitas tak optimal).

- 1:100 000 scale black/white aerial photography, Australian Airforce, 1976, (usually poor quality due to recopying and poor processing). - 1:250,000 LANDSAT colour composites (bands 4-5-6), 1985, obtained from LAPAN (varying quality, inacurate scale). - 1:250,000 STAR-1 stereo Radar imagery, 1988 (black/white positive prints, quality not optimal).

2.3.Survei dan data lapangan.

2.3.Field survey and field data

Pelaksanaan survei tinjau dapat dibagi dalam beberapa tahapan kerja:

The implementation of the reconnaissance survey can be split up into a number of essential steps :

1. penelaahan data dan informasi dari peta dan laporan tersedia. 2. interpretasi citra dan penetapan daerah kunci 3. pengamatan lapangan dan pemasukan data ke komputer 4.penyusunan satuan lahan dan pemasukan data ke komputer. 5.analisis contoh tanah 6.melengkapi uralan satuan lahan dengan data analisis. 7. korelasi/verifikasi lapangan 8. produksi peta akhir 9.dijitasi peta dan pemrosesan data base lainnya. Semua pengamatan di lapangan (pemboran dan profil) dicatat, diberi kode dan dimasukan sesuai dengan prosedur standar PDBT, seperti diuraikan dalam Laporan Tehnis PDBT No.5 (Balsem et al., 1988). Kode ini terutama diadaptasi dari standar FAO dan USDA (FAO, 1977; SCS, 1978; Gallup, 1978). Contoh tanah yang représentatif dianalisis sifat-sifatnya seperti yang disajikan pada Tabel 2 .

2.5. Data base dan pengolahan data.

2.5.Data

Seperti disebutkan diatas, semua data lapangan dan analisis disimpan dalam data base. Data base yang utama ialah: -pengamatan lapangan (pemboran dan penampang tanah). -data analisis -uraian satuan lahan

As mentioned above, all field and analytical data are stored in computerized data bases. The main data bases are : - field observations (auger and pit). - analytical data - land unit descriptions

Data base pengamatan lapangan berisi semua parameter yang dapat diukur di lapangan dari setiap tempat pengamatan. Yang didiskripsi dan disimpan adalah nomor tempat/site, tempat, lereng, vegetasi/penggunaan lahan dan semua sifat-sifat tanah yang diukur di lapangan seperti Struktur, porositas, tekstur, warna, dll. (lihat Laporan Teknis No 5a, Versi 1.1, (Baisem et al. , 1988).

The field observations data base contains all parameters that were measured in the field, for each of the observations sites. Described and stored are site number, location, slope, vegetation/landuse and all soil properties that are measured in the field, such as structure, porosity, texture, colour etc (see Technical Report No 5 - Balsem et al., 1988)

Data base analisis berisi semua hasil analisis kimia, fisika dan mineralogi serta semua data hasil perhitungan dari analisis ini yang biasanya dipergunakan untuk menilai kesuburan atau klasifikasi tanah (Lihat Laporan Teknis No 7a - Buurman, 1988; Laporan Teknis No 17 - Muslihat et al., 1989).

The analytical data base contains all results of chemical , physical and mineralogical analy ses and all properties used for fertility appraisal or class ification, that are calculated with these analyses (see Technical Report No 7 - Buurman, 1988; and Technical Report No 17 - Muslihat et al., 1989).

Pada data base pengamatan lapangan dan data base analisis, data dapat dikeluarkan dengan cara memanggil /menuliskan nomor pengamatan, nomor lembar peta, satuan pada legenda, administrasi (kabupaten atau provinsi) atau dengan yang lainnya yang ditentukan oleh koordinat geografik.

In both the field observations and in the analytical data base, data can be retrieved by observations number, mapsheet, legend unit, administrative area (province, kabupaten), and other areas defined by geographic coordinates.

Data base uraian satuan lahan berisi uraian umum dari tiap satuan peta untuk seluruh Pulau Sumatera yang dikatalogkan menurut lembar peta.

The land unit description data base contains the general description of each mapping unit for the whole island of Sumatra, catalogued by mapsheet.

Uraian umum berasal dari penyederhanaan semua pengamatan pada seluruh satuan p e t a , termasuk analisis laboratorium dari profil yang l a i n . Parameter yang disimpan berisi semua informasi yang diperlukan untuk p e n i l a i a n e v a l u a s i lahan ( l i h a t Laporan Teknis No 13 - Balsem & Buurman, 1989). Uraian satuan lahan dari semua satuan peta yang terdapat dalam lembar peta ini disajikan pada Lampi ran 1.

The general description is derived by generalizing information of all observations within the mapping unit, including laboratory analyses of separate profiles. The parameters stored contain all the information necessary for land evaluation procedures (see Technical Report No. 13 Balsem & Buurman, 1989). The land unit descript ions of all mapping units relevant to the present sheet are listed in Appendix 1.

2.6.Relaibilitas peta

2.6. Map reliability

Relaibilitas dari peta tergantung pada beberapa faktor seperti: kerapatan pengamatan, keragaman tanah, kualitas dari citra penginderaan jauh, lokasi dari titik pengamatan atau daerah kunci, ketepatan dari batas tanah maupun batas satuan lahan, tingkat pengetahuan dan pengalaman surveyor. Tidak semua dari faktor faktor ini dapat diukur dan karena itu harus diperkirakan.

The reliability of a map depends on many such factors as observation density, soil homogeneity or complexity, quality of the remote sensing imagery, the location of sample/key areas, accuracy of soil units and soil boundaries, the level of education and the amount of experience of the soil surveyor'. Not all of these can be measured and so they have to be estimated.

Berdasarkan faktor faktor tersebut diatas, terutama kerapatan pengamatan, maka diperkirakan raengenai relaibilitas peta, dan untuk itu dibagi menjadi 3 grup (Gambar 2).

Based on the above mentioned factors mainly on observation density, three classes of map reliability have been established (Figure 2).

4. KEADAAN UMUM FISIK DAERAH 4.1. Fisiografi Bentang alam daerah lembar peta Toboali dapat dibedakan kedalam Lahan Basah (Lowland), Lahan Kering (Upland) dan Perbukitan. Lahan Basah selanjutnya dibagi lagi menjadi Grup Kubah Gambut, Grup Marin dan Grup Aluvial, sedangkan Lahan Kering terdiri dari Grup Dataran. Lahan Basah (Lowland f Lahan. Basah yang termasuk kedalam Grup Marin menempati daerah sepanjang pantai dengan lebarnya bervariasi antara 2.5 dan 35 km. Daerah lahan basah ini merupakan hasil dari proses sedimentasi marin dan perimarin (delta dan kuala) dan secara jelas dapat dibuktikan dengan adanya pelebaran pantai yang disebabkan oleh penambahan bahan endapan dan proses angkatan.

daerah yang masih muda. Karena sebagian besar daerah ini mempunyai drainase terhambat, tanahnya umumnya belum matang atau setengah matang (half ripe). Tergantung vegetasi aslinya dan dimana daerahnya banyak mengandung pirit, maka akan terbentuk tanah sulfat masam atau potensial sulfat masam. Daerah-daerah yang dekat dengan pantai dan sepanjang sungai akan dipengaruhi oleh pasang surut. Daerah demikian biasanya ditumbuhi vegetasi nipah atau mangrove dan tidak tergenang pada waktu surut. Daerah yang jauh dari laut menjadi rawa permanen dan bersifat payau, dan umumnya ditumbuhi oleh hutan gelam atau vegetasi rendah seperti rumput. Hutan lebat hanya dijumpai pada daerah marin tua, dimana semua kadar garam terlarutnya telah tercuci. Di bagian selatan peta dijumpai sisa jalur beting pantai dan cekungan (beach ridges and swales). Jalur ini terdapat agak jauh dari laut dan sebagian tidak memanjang garis pantai dan telah tererosi. Beting pantai tua ini umumnya telah kehilangan karbonat yang turun kebawah sampai permukaan air tanah, dan tanahnya telah mengalami perkembangan. Perkembangan tanah ini pada daerah cekungan tidak nyata. Pada garis pantai, Grup Marin ditandai oleh adanya dataran mangrove dan tanahnya belum matang. Daerah rawa luas antara jalur mangrove dan beting pantai tua kemungkinan mengandung bahan organik yang cukup tebal atau mempunyai tanah-tanah yang serupa dengan tanah-tanah pada dataran mangrove. Daerahnya basah sepanjang tahun. Daerah yang termasuk Grup Aluvial dijurapai disebelah barat dari Grup Marin, terutama di bagian selatan peta. Grup Aluvial ditandai oleh adanya pelembahan aluvial luas dan pelembahan erosif di daerah Dataran. Pelembahan aluvial luas (A.1.2) terutama membentuk rawa belakang yang luas yang selalu jenuh air. Tanahnya

sebagian belum matang dan kadangkadang ditutupi oleh bahan organik tebal. Tanggul sepanjang sungai utama sedikit lebih tinggi letaknya dari rawa belakang, dan terbentuk dari bahan endapan halus. Tanah-tanah di daerah ini hampir serupa dengan tanah pada rawa belakang, hanya drainasenya lebih baik sedikit. Pelembahan aluvial di daerah Dataran umumnya erosif dan hanya sedikit mengandung bahan endapan. Kubah gambut dijumpai pada bagian utara lembar peta ini dan luasnya cukup besar. Dibandingkan dengan pantai disebelah utara seperti di Riau dan Jambi, kubah gambut disini relatif terbatas penyebarannya dan ketebalan bahan organiknya lebih tipis. Secara umum dapat dikatakan bahwa ketebalan bahan organik bertambah jika makin jauh dari sungai. Lapisan liât dibawah lapisan bahan organik umumnya mengandung pirit dan karenanya terbentuk tanah-tanah potensi sulfat masam. Lahan Kering (Uplands) Lahan kering hanya diwakili oleh satu Grup Fisiografi, ialah Grup Dataran. Tanah-tanah pada Grup Dataran terbentuk dari bahan bukan volkan dari zaman Tersier, yang umumnya berasal dari laut dangkal. Di lapangan tidak selalu dapat dengan mudah dibedakan dari bahan Dataran Tuf Masam yang sudah lapuk, raeskipun sifat kimia dan mineraloginya berbeda, nyata. Tutupan bahan ignimbrit Kuarter menipis dari Teluk Lampung menuju arah utara dan hanya ditemukan di bagian barat laut lembar peta ini. Karena Dataran punya sejarah yang cukup kompleks, banyak sisa tanda proses pembentukan tanah dijumpai, seperti tutupan konkresi besi, lapisan plintit, dll. Pada beberapa daerah, dijumpai sisa dari teras sungai. Di lembar peta ini, kisaran ketinggian dari Grup Dataran antara 10-70m diatas

1112 - 15

muka laut. Pembagian lebih lanjut dari Grup Dataran berdasarkan morfologi bentang alam dan tingkat torehan. Karena proses pembentukan tanah jauh lebih tua dari proses penorehan (erosi), maka perbedaan adalah antara profil tanah lengkap (tererosi sedikit) pada daerah punggung, dan profil tanah tererosi ringan sampai berat pada lereng. Tanah hidromorfik terdapat pada lereng bawah/ perali'han ke lembah. Tanah umumnya mempunyai perbedaan tekstur yang nyata antara horison A dan B dan karenanya diklasifikasikan sebagal 'Kanhapludults'. Tanah yang telah tererosi umumnya diklasifikasikan sebagai Dystropepts sedangkan yang terkena pengaruh genangan air sebagai Tropaquepts. Sifat-sifat kimia dari tanah-tanah ini umumnya miskin dan mempunyai kadar aluminium yang cukup tinggi pada lapisan bawah. Pada bagian yang lebih tua dari Grup Dataran, tanahnya sudah mengalami perkembangan lanjut dan diklasifikasikan sebagai Oxisols (Hapludox). Perbukitan Perbukitan pada lembar peta ini hanya ditemukan di Pulau Bangka dan merupakan sisa i n t r u s i sienit yang terdapat di Batuampar sebelah utara jalan antara Pampangan dan Tulungs e 1apan ( b a r a t l a u t Pulau Bangka). Intrusi batuan plutonik ini muncul dipermukaan sebagai singkapan diantara sedimen Palembang.

4.2. Geologi Formasl geologi didaerah yang dicakup lembar peta ini termasuk dalam PreTersier, Tersier dan Kuarter. Pre-Tersier Formasi batuan plutonik sienit (pTsy) dan Formasi batuan plutonik granit (pTgr) serta Formasi batuan metamorfik skis termasuk dalam Pre-Tersier; formasi-formasi tersebut masing-masing terdapat di Batuampar (utara jalan Tulungselapan-Pampangan dan di utara dan selatan Toboali (Pulau Bangka). Ketinggian tempat intrusi sienit dan granit antara 30m (utara Pampangan) dan 292m (timurlaut Toboali); skis Bangka terdapat antara 10 dan 25m dpi. Batuan sienit menempati inti antiklinal dan tertutup oleh Formasi Palembang bawah. Batuan granit sekitar Toboali tergolong amfibolgranit berbutir sedang sampai kasar dan tidak mengandung kasiterit (oxida timah). Skis Toboali yang umumnya berwarna hijau muda mengandung mika, khlorit dan talk. Tersier Formasi Palembang Anggota Bawah (Tmpl) dan Formasi Palembang Anggota Tengah (Tppp) mewakili sedimen Tersier di daerah peta ini. Formasi-formasi ini masing-masing disebut Formasi Air Benakat dan Formasi Muara Enim.

Bentuk wilayah intrusi sienit terdiri dari bukit-bukit kecil terpisah (.isolated hillocks). Berdasarkan adanya singkapan batuan plutonik di daerah ini dapat diduga bahwa gejala t e r s e b u t merupakan akibat proses peneplainasl.

Formasi Palembang Anggota Bawah yang terdapat di baratlaut terdiri dari batulempung, serpih- dan batupasir glaukonitan yang merupakan endapan lingkungan neritik. Batulempung berselingan dengan batupasir lempungan glaukonitan. Tmpl di selatan Batuampar yang mempunyai kemiringan lapisan keselatan sebesar 1 sampai 7% merupakan sayap antiklinal yang bersumbu kira-kira timur-barat.

Tanah diatas sienit umumnya mempunyai perbedaan tekstur yang nyata antara horison A dan B dan diklasifikasikan sebagai Ultisol. Tanah yang telah tererosi diklasifikasikan sebagai Inceptisol.

Formasi Palembang Anggota Tengah (Miosen Atas - Pliosen) yang sebagian besar terdapat di tengah dan selatan terdiri dari batupasir, batulumpur yang banyak berselingan dengan lapisan batubara. Tppp di bagian atas umumnya

1112 - 16

terdiri dari endapan air payau dan endapan rawa dengan lapisan batubara seperti yang terdapat di sekitar Muara Enim. Tppp terletak selaras pada Tmpl, sebaliknya Tppp tertutup tak-selaras oleh Tuf Ranau. Ketebalan Tppp diperkirakan berkisar antara 600 dan 800m. Kuarter Kuarter terdiri dari formasi Tuf Ranau dan Aluvium termasuk Holosen. Formasi Tuf Ranau (Qrv) terdäpat di utara Pematangsipanggang membujur ke timurlaut. Formasi Tuf Ranau berupa tuf lempungan, tuf liparit mengandung kuarsa, blotit dan plagioklas masam dan berasal dari pusat erupsi Danau Ranau (lembar Kotabumi) yang terletak di baratdaya. Tuf di pusat erupsi menunjukkan perlapisan dan bersusunan biotit liparit dengan kandungan yang sama seperti Qrv di lembar Toboali, namun dengan kandungan fragmen batuapung, sanidin dan magnetit. Ketebalan tuf ini di dekat pusat erupsi ± 150-200 m dan menipis ke utara dan timurlaut sampal ujungnya yakni Qrv di daerah ini. Qrv ditutup tak-selaras oleh endapan Holosen. Aluvium terdiri dari pasir, debu, liât dan bahart organik yang merupakan endapan subresen dan muda dengan penyebaran paling luas di dataran rendah pantai dan pasang surut, pelembahan sungai, rawa belakang dan cekungan.

4.3. Hidrologi Secara keseluruhan kawasan timur Sumatera, Pulau Bangka dan P.Belitung serta pulau-pulau lalnnya menunjukkan ciri-ciri tenggelamnya dataran rendah dibawah permukaan pada zaman Kuarter tua. Maka oleh sebab itu, daerah agak datar dan keadaan tata air di daerah datar ini dikendalikan oleh gradient kecil sehingga drainase terhambat dengan akibat penggenangan yang luas dan bersifat permanen. Keadaan ini dominan terjadi di rawa belakang dan

cekungan di sekitar Way Mesuji dan Sungai Lumpur. Berdasarkan pengaruh pasang surut dataran rendah dapat diidentifikasi sebagai daerah yang sedikit atau sama sekali tanpa pengaruh pasang surut yakni jalur aliran sungai perenial dan tawar, dataran banjir musiman, rawa belakang air tawar bergambut masam; batas kawasan ini dengan pengaruh pasang surut sangat ditentukan oleh jauhhya intrusi pasang besar di musim kemarau dan desakan balik air- sungai waktu musim penghujan (NEDECO, 1981). Oleh sebab itu sungai-sungai yang relatif pendek dengan desakan air tawar kurang kuat untuk menekan air laut, kemungkinan besar pengaruh pasang surut terasa jauh ke pedalaman, a.l dapat diamati pada Sungai Mesuji dan S.Lumpur yang tergolong pendek. Dataran rendah yang langsung terkena pasang surut di daerah ini tampak jelas yakni sejauh alur-alur pasang surut (tidal kreeks) yang panjangnya antara 2 sampai 5 km, bahkan ada yang 10 km lebih: dari selatan ke utara Sungai Siburbesar, S.Jerwu, S.Lebonghitam, S.Riding dan S.Pidada.. Daerah yang relatif kering adalah dataran Formasi Palembang yang agak meninggi dibandingkan daerah tergenang di sekitarnya. Daerah pematang. bagian selatan merupakan dataran berombak, didrainase oleh Sungai Mesuji dan cabangnya a.l. S.Dabukputih, S.Dabukitem, S.Talangbatin, yang berpola dendritik. Daerah pematang di tengah dan di utara didrainase a.l. oleh Sungai Jeruju, S.Pasir, S.Selapan dan S.Belidang (keduanya cabang S.Lumpur) yang dendritik. Keadaan tata air dl daerah Pulau Bangka sekitar Toboall berbeda antara daerah granit dan skis yang umumnya berdrainase baik dan dataran rendah yang berdrainase terhambat dan bahkan setempat-setempat tergenang permanen dan musiman serta daerah pantai dengan pengaruh pasang surut.

5.SATUAN LAHAN

tetapi sering raengandung pirit. Jenis tanah yang mendorainasi satuan lahan ini adalah Tropohemists dan Sulfihemists.

5.1.Satuan lahan dan tanah. Seperti telah disebutkan pada bab terdahulu, satuan lahan yang dijumpai pada lembar peta ini dapat dikelompokkan kedalam 5 grup fisiografi, yaitu Grup Kubah Gambut, Grup Aluvial, Grup Marin, Grup Dataran, Grup Perbukitan dan Grup Aneka Bentuk (Gambar 6). Pada setiap satuan lahan umumnya ditemukan lebih dari satu satuan tanah (pada tingkat Great G r o u p ) , dan agar memudahkan pembacaannya maka setiap satuan tanah yang dijumpai pada setiap satuan lahan ditentukan luas penyebarannya secara kualitatif, yaitu: -Sangat dominan: apabila penyebarannya >75% dari luasan satuan lahan. -Dominan: apabiia penyebarannya antara 50-75% dari luasan satuan lahan. -Cukup: apabila penyebarannya antara 25-50% dari luasan satuan lahan. -Sedikit: apabila penyebarannya antara 10-25% dari luasan satuan lahan. -Sedikit sekali: apabila penyebarannya <10% dari luasan satuan lahan. Dibawah ini akan diuraikan mengenai keadaan tanah yang dijumpai pada setiap grup fisiografi. Grup Kubah Gambut Di daerah ini dijumpai kubah gambut oligotropik air tawar dan yang terpengaruh air asin, terbentuk di daerah yang relatif cekung sehingga daerahnya tergenang sepanjang tahun. Dalam lingkungan demikian sisa tumbuhan sukar hancur dan menumpuk sebagai gambut dengan atau tanpa campuran endapan tanah mineral. Ketebalan gambut bervariasi antara 0,5 dan 4m. Bentuk permukaan seperti kubah dengan perbedaan tinggi tidak melebihi 10 m. Bahan organik telah mengalami dekomposisi menjadi hemist dan saprisc serta diperkirakan komposisi abunya tidak kaya akan unsur-unsur hara (oligotrofik). Bahan mineral di bawah gambut umumnya miskin unsur, khusus kalau teksturnya kasar. Bahan halus dari sedimen marin umumnya lebih kaya,

Daerah ini pada umuranya untuk jangka pendek tidak mempunyai nllai untuk dikembangkan sebagai daerah pertanian. Kecuali sesetempat di bagian pinggir yang ditempati jenis tanah Tropaquents dapat dijadikan untuk areal persawahan lebak dalam luasan yang sempit dan dengan pengendalian air yang baik. Penghambat utama di daerah ini adalah kandungan unsur hara/miskin, ketebalan gambut dan genangan permanen serta bahaya keracunan pirit (Sulfihemists). Grup Aluvial. Tanah tanah pada grup fisiografi ini umumnya berkembang dari bahan endapan halus dan Hydraquents merupakan tanah yang dominan dijumpai pada Dataran Aluvial Luas (A.1.1), sedangkan tanah yang lainnya ialah Tropaquents, Fluvaquents, Tropohemist dan Sulfaquents. Hydraquents merupakan tanah yang belum matang, kandungan airnya tinggi dan drainasenya sangat terhambat. Tingkat kesuburannya tidak begitu menjadi masalah dimana diantaranya mempunyai kadar P total dan nllai Kapasitas Tukar Kation tinggi. Tanah tanah pada Lembah Aluvial Luas (A.1.2) cukup bervariasi, yaitu Tropaquepts, Tropaquents, Fluvaquents, Sulfihemist dan Dystropepts . Juga berkembang dari bahan endapan halus. Diantara semua tanah ini maka Sulfihemist yang terutama akan menjadi masalah bagi pertanian yaitu mengandung kadar pirit cukup tinggi yang akan membahayakan tanaman. Tanah lainnya yang menjadi masalah hanya persoalan drainase yang termasuk terhambat sampai sangat terhambat, kecuali Dystropepts mempunyai drainase baik.

Grup Marin. Pada Grup Marin tanah yang paling banyak di jumpai adalah Hydraquents, Sulfaquents dan Sulfihemists sedangkan yang lainnya adalah Fluvaquent s dan Tropaquents. Terbentuk dari bahan endapan halus. Sifat s i f a t dan permasalahan tanah Hydraquents saroa seperti Hydraquents yang di jumpai pada Dataran aluvial luas. Seperti halnya pada Dataran aluvial luas, maka tanah tanah yang terutama menjadi masalah ialah Sulfo/Sul fihemist dan Sulfaquents yang mempunyai kadar piri t yang cukup tinggi yang akan membahayakan tanaman jika daerahnya dibuka dan didrainase, karena akan memberikan pH yang sangat rendah. Grup Dataran. Tanah tanah didaerah i n i umumnya berkembang dari batuan ^pHimen halus maupun kasar yang berasal dari forraasi Palembang Tengah dan Bawah.

lukan penelitian lebih d e t a i l . Adanya lapisan kongkresi Fe pada daerah perakaran pada penampang tanah akan sangat menganggu pertumbuhan akar tanaman. Adanya lapisan p l i n t i t juga kurang baik bagi tanaman, karena jika lapisan ini kontak dengan udara akan menjadi sangat keras. Jadi pada tanah tanah yang mengandung lapisan p l i n t i t harus diusahakan pengolahan tidak sampai pada lapisan tersebut. Disebutkan d i a t a s Kanhapludults merupakan t a n a h yang mendorainasi daerah i n i . Perrnasalahan utama dari t a n a h i n i i a l a h mempunyai n i l a i Kapasitas Tukar Kation yang rendah. yaitu <16 cmol(+)/kg l i â t . Tanah-tanah ini kurang dapat nenyimpan pupuk jika dilakukan pemupukan. sehingga cara pemberian pupuk pada tanah ini mtujadi masalah yang utama. Salah satu caranya ialah dengan raemberikannya secara bertahap. Salah satu cara mengatasi rendahnya n i l a i Kapasitas Tukar Kation ini ialah dengan penambahan bahan organik.

Menurut k l a s i f i k a s i USDA tanah yang banyak dijurapai di daerah Dataran ialah Kanhapludults, Dystropepts dan Tropaquepts, dimana tanah yang d i s e but kan pertama mend orai nasi dal ara hal Tanah lainnya yang di jumpai i a l a h penyebarannya.
