Judul: Analisis pendapatan petani Padi sawah di Desa Ciasihan Kecamatan Pamijahan Kabupaten Bogor
Abstrak: Rice production in Indonesia is getting decreased due to the presence of land conversion to non-agricultural sector. One area of West Java that having decline of crop land area is Bogor District. Production decrease of 7.54% from 2010 is caused by the reduced of crop land area that reaches 6 183 ha from 2010 to 2011. Increasing rice productivity isn’t always able to increase the amount of milled rice production if it is followed by a decrease in crop land area. The objectives of this research are to identify performance of rice farmers and analyze the income of rice farming in the Ciasihan Village. The research results indicate that rice farming is still viable seen from the amount of income, is Rp 5.545.169/season. The value of the ratio R / C of rice farming in the ciasihan village is 1.33. Therefore, to increase the income of farmers, the government can provide training and counseling, supporting equipment,and facilities for meetings.

Judul: Pendapatan Usahatani Padi Sawah dengan Sistem Tanam Jajar Legowo di Desa Ciasmara Kecamatan Pamijahan Kabupaten Bogor.
Abstrak: Beras merupakan makanan pokok bagi masyarakat Indonesia. Tingginya konsumsi beras nasional mendorong pemerintah untuk mengupayakan berbagai kebijakan untuk memenuhi kebutuhan beras. Pemerintah mengeluarkan program untuk meningkatkan produktivitas padi salah satunya melalui sistem tanam jajar legowo. Salah satu program penerapan sistem tanam jajar legowo dilakukan di Desa Ciasmara, Kecamatan Pamijahan, Bogor. Meskipun didukung oleh pemerintah kenyataan di lapangan masih terdapat petani yang tidak menerapkan sistem tanam jajar legowo. Penelitian ini bertujuan untuk menganalisis pendapatan usahatani padi dengan sistem tanam jajar legowo dan non-jajar legowo yang meliputi struktur biaya dan penerimaan usahatani. Penelitian dilakukan di Desa Ciasmara dengan jumlah sampel sebanyak 30 petani yang terdiri dari 14 petani jajar legowo dan 16 petani non-jajar legowo. Metode penarikan sampel dilakukan dengan cara purposive dan snowball. Hasil penelitian menunjukan bahwa pendapatan dan nilai R/C rasio pada sistem tanam jajar legowo memperoleh hasil yang lebih besar dibandingkan dengan sistem tanam non-jajar legowo. Hasil uji statistik menunjukan bahwa ada perbedaan secara statistik pada komponen produksi, penerimaan dan pendapatan dan tidak terdapat perbedaan secara statistik pada komponen biaya

Judul: Sintesis dan Pencirian Kompleks Fe(III)-Kuersetin
Abstrak: Quercetin belongs to flavonols which is able to chelate metal ions. Quercetin may chelate metal ions at 3’,4’-catechol, 3- or 5-hydroxycromone sites. In this study, quercetin was complexed with Fe(III). The complex with Fe(III) ions from FeCl3·6H2O was more stable than the complex derived from Fe(NO3)3·9H2O. The quercetin was yellow in color and showed maximum wavelengths (λ􀭫􀭟􀭶) at 250 and 370 nm. The Fe(III)-quercetin complex from Fe(NO3)3·9H2O was yellowish green with 􀟣􀭫􀭟􀭶 at 280 and 420 nm, whereas that from FeCl3·6H2O was dark green with 􀟣􀭫􀭟􀭶 at 280 and 430 nm. The 􀟣􀭫􀭟􀭶 shift indicated that the complex was formed at 3-hydroxychromone site. The Fe(III)- quercetin complex was formed with 1:1 metal-ligand mole ratio based on atomic absorption spectrophotometry analysis and the X-ray diffractogram showed that the crystallinity of the complex was 37%.
