Judul: Factors Affecting Migration of Rice Farming Family Members and Their Contribution to the Farming Household (Case Study: Bawean Island, Gresik Regency)
Abstrak: Mayoritas pekerjaan masyarakat di Pulau Bawean adalah petani padi. Petani padi yang tinggal di Pulau Bawean didominasi oleh petani yang berusia lanjut. Banyak laki-laki yang masih berusia produktif memilih untuk tidak menjadi petani, khususnya petani padi. Mereka memilih bekerja di sektor non pertanian, salah satunya adalah menjadi pekerja migran. Penelitian ini bertujuan untuk: (1) menganalisis pendapatan usatahani padi, (2) menganalisis kontribusi remitan terhadap pendapatan rumahtangga petani padi, (3) menganalisis faktor - faktor yang memengaruhi migrasi anggota keluarga petani padi. Penelitian ini menggunakan analisis pendapatan usahatani, analisis kontribusi pendapatan dan analisis regresi model logistik biner. Hasil penelitian ini menunjukkan nilai R/C ratio atas biaya tunai dan atas biaya total lebih dari satu artinya usahatani padi di Pulau Bawean menguntungkan. Kontribusi pendapatan yang paling besar kontribusinya terhadap pendapatan total keluarga petani adalah remitan dan pendapatan usahatani yang menjadi sumber pendapatan utama bagi keluarga petani berada di urutan ketiga setelah kontribusi remitan dan pendapatan non usahatani. Faktor-faktor yang berpengaruh secara signifikan terhadap keputusan migrasi anggota keluarga petani padi adalah pendapatan responden, pendapatan keluarga responden dan riwayat pekerjaan.

Judul: Pengaruh Migrasi Sirkuler Terhadap Kondisi Sosial Rumah Tangga Petani
Abstrak: The objectives of this research was to identify the push and pull factors that influence household decisions farmers circular migration, as well as analyzing the effect arising from circular migration to changes in children's education, social roles, patterns of farmers working hours, and the division of labor in farm households. The research was conducted in the Desa Pamanukan Hilir, Kecamatan Pamanukan, Kabupaten Subang. The research uses a quantitative approach to qualitative data supported by survey research methods. In the study it was found that circular migration affects the social conditions of farming households, among them: 1) The main factor farmers kepememiliki circular migration due to lack of land that affect the level of income (economics); (2) Farmers who migrated circularly adjust the division of labor in the household; (3) Households of migrant farmers have more motivation to achieve higher education of children; (4) Farmers use the grace period to work outside the agricultural sector, which affects the reduction of working hours in farming; and (5) Most of the social role of husband and wife when the husband is replaced doing migration.

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%.
