75 BAB V KESIMPULAN DAN SARAN 5.1 Kesimpulan Kesimpulan yang diperoleh dari penelitian ini berdasarkan analisa data dan pengamatan adalah sebagai berikut : 1. Buah Mangsi (phyllanthus reticulatus poir) sebagai zat warna pada SSPT memberikan nilai efisiensi yang lebih besar jika dibandingkan campuran zat warna pacar kuku-mangsi maupun pacar kuku (Lawsonia inermis) 2. Nilai efisiensi sel surya pewarna tersensitisasi yang direndam dalam zat warna mangsi sebesar 2.36 x 10-2 % sementara efisiensi sel surya yang direndam dalam campuran pacar kuku-mangsi 1:3 dan pacar kuku sebesar 1.17 x 10-2 % dan 2.24 x 10-3 %. 3. Campuran pacar kuku-mangsi dengan perbandingan 1:3 memberikan efisiensi yang lebih besar dari pada campuran pacar kuku-mangsi pada komposisi lainya. 5.2 Saran Saran yang dapat diberikan dari penelitian ini adalah perlu dilakukan penelitian lebih lanjut tentang teknik pelapisan fotokatalisis semikonduktor TiO2 sehingga diperoleh lapisan yang rata. Selain itu, penggunaan pacar kuku sebagai zat warna pada SSPT perlu dikaji lebih lanjut.
