Judul: Keragaan dan Pendapatan Usahatani Padi Program SLPTT dan Non Program SLPTT di Desa Sukaratu, Kecamatan Gekbrong, Kabupaten Cianjur
Abstrak: Rice is the staple food for Indonesia. This can be indicated from the high rice consumption number, which is 102 kg per capita. Government has released Program Peningkatan Produksi Bears Nasional (P2BN) with Sekolah Lapang Pengelolaan Tanaman Terpadu (SLPTT) as its instruments. Sukaratu village is one of the rice producers which have received the SLPTT program on year 2012. This study analyses the performance of rice farming of SLPTT and non SLPTT program, evaluates the implementation of SLPTT program in Sukaratu village, and analyses the income of rice farm business from SLPTT and non SLPTT program. The data were collected by direct structured interview with the rice farmers in Sukaratu Village. The result shows that the yield and the income of rice farm business from SLPTT program are 6.00 ton per ha and Rp 9 382 641, these numbers are higher than the non SLPTT program which are 5.17 ton per ha and Rp 6 538 504. Rice farm business from SLPTT program is more efficient than the non

Judul: Dampak Program Bantuan Langsung Benih Unggul terhadap Ekonomi Rumahtangga Petani Padi di Desa Bangunharja Kecamatan Cisaga Kabupaten Ciamis
Abstrak: Agriculture is one of the main sectors in the Indonesian economy. One of the sub-sectors of agriculture that promotes economic growth is that of food crop production. Rice is one of highly produced agricultural product in indonesia.This is because it is the staple food in Indonesia. Bangunharja is one of the villages in Ciamis that is capable of producing large quantities of rice. Farmers should be able to earn a decent income from farming, however most farmers can do not thrive in this business. The government has formed BLBU Program (Direct Superior Seeds aid program). The purpose of the study is: (1) identify the characteristics of farmers and the implementation of the Direct Superior Seeds Aid Program at Village Bangunharja, (2) analyze the factors that influence the decision by farming households in allocating the outpouring of work, production and expenditure of households in the village Bangunharja, and (3) comparing the impact of Superior Seeds Direct aid Program to the economy of household farmers BLBU and Non BLBU in Bangunharja village. This study uses cross section data from sample of households within Bangunharja village in the year 2013. Bangunharja farm household economic model is built as simultaneous equations system and estimated using Two Stage Least Squares (2SLS). Increase in the amount of seed aid (BLBU 100 percent) increases household expenditures farmers. Wherease for farmers who did not receive BLBU, an increasing number of seed aid (50 percent of total seeds) can increase household expenditures farmers.

Judul: Kendali Ukuran Nanopartikel Magnetik Oksida Besi (Fe3O4/γ-Fe2O3) dengan Modifikasi Kekuatan Ionik untuk Aplikasi Biomedis
Abstrak: Nanopartikel yang digunakan dalam bidang biomedis harus stabil terdispersi. Untuk itu, diperlukan penyalutan dengan material lain. Salah satu material yang dapat digunakan adalah apoferitin yang hanya memiliki ukuran diameter bagian dalam 8 nm. Penelitian ini bertujuan mengendalikan kekuatan ionik dari media dengan modifikasi NaNO3 dan agen peptisasi HNO3 agar diperoleh magnetit dengan ukuran partikel 8 nm yang stabil terdispersi dan memiliki nilai magnetisasi saturasi tinggi. Partikel magnetit dengan ukuran 8 nm berhasil disintesis dengan modifikasi NaNO3. Hasil analisis difraktometer sinar-X dan mikroskop elektron transmisi menunjukkan modifikasi NaNO3 menyebabkan penurunan ukuran kristalit dan ukuran partikel magnetit. Ukuran partikel yang diperoleh kurang dari 10 nm. Hasil analisis sifat magnet dengan vibrating sample magnetometer menunjukkan partikel magnetit yang diperoleh memiliki nilai magnetisasi saturasi tinggi. Pola distribusi ukuran partikel menunjukkan pengaruh tambahan HNO3 menyebabkan nanopartikel magnetit menjadi lebih terdispersi serta waktu penambahan NaNO3 sebelum atau setelah presipitasi berpengaruh pada keseragaman ukuran partikel magnetit yang diperoleh. Kondisi optimum sintesis nanopartikel diperoleh saat konsentrasi NaNO3 6 M yang ditambahkan sebelum presipitasi serta dengan tambahan agen peptisasi HNO3 1 M.
