BAB 5 KESIMPULAN DAN SARAN 5.1 Kesimpulan Berdasarkan hasil penelitian dan analisa, diperoleh kesimpulan sebagai berikut : 1. Kadar lipid total mikroalga Nannochloropsis oculata yang diperoleh dalam penelitian ini berkisar antara 36 – 37 %. Metil ester yang dihasilkan dari metode transesterifikasi menggunakan BF3-metanol 14% pada suhu 60 oC selama 30 menit sebesar 86 %. 2. Metil ester asam lemak yang terdapat di dalam mikroalga Nannochloropsis oculata antara lain adalah metil laurat 0,46 %, metil miristat 6,20 %, metil pentadekanoat 0,50 %, metil palmitoleat 24,96 %, metil palmitat 39,82 %, metil linoleat 1,01 %, metil oleat 3,75 %, metil stearat 0,97 % dan metil eikosapentaenoat (EPA) 5,91 %. Kandungan metil ester tertinggi adalah metil palmitat yaitu sebesar 39,82 %.
5.2 Saran Berdasarkan penelitian yang telah dilakukan, maka disarankan beberapa hal sebagai berikut : 1. Perlu dilakukan penelitian lebih lanjut tentang optimasi transesterifikasi menggunakan BF3-metanol 14% dengan melakukan variasi suhu dan waktu reaksi. 2. Laju reaksi dari transesterifikasi dapat diteliti lebih lanjut untuk mengetahui pengaruh dari suhu dan waktu reaksi terhadap jumlah metil ester yang dihasilkan.
