Judul: Curahan kerja, kontribusi anggota keluarga dalam pendapatan rumahtangga dan pola pengeluaran nelayan tradisional di Kabupaten Brebes Jawa Tengah
Abstrak: A number of studies on fishermen’s lives generally focus on poverty and economic uncertainty as a result of living difficulties faced by fishermen and their families. At present, most households do not have only one income source but several sources. In other words, they do diversified jobs or have various income sources. However, the problem is that the opportunity cost or any possible activities the fishermen can do when they do not catch fish is very low and they tend to do the activities although they are not profitable and efficient. The objectives of this research were to analyze the factors that affect the allocation of working time among the households of traditional fishermen who use payang as a catching tool and to examine the factors that influence their income and expenditure. This study used cross sectional data. The model built in this study was intended to be able to identify the economic behaviors among the households of traditional fishermen in Brebes Regency, Central Java, based on the existing data and the results of previous studies with the support of relevant theories.

Judul: Analisis Peran Gender dan Perilaku Menabung Pada Keluarga Nelayan (Studi di Kelurahan Palabuhanratu Kabupaten Sukabumi)
Abstrak: Ketidakpastian pendapatan yang diperoleh nelayan membuat keluarga nelayan harus mempunyai manajemen keuangan yang baik untuk dapat memenuhi kebutuhan keluarga dan mencapai kesejahteraan keluarga. Penelitian ini bertujuan untuk menganalisis peran gender dan perilaku menabung serta pengaruhnya terhadap kesejahteraan keluarga. Penelitian ini melibatkan 60 keluarga: 30 nelayan buruh dan 30 nelayan pemilik yang dipilih secara purposive. Hasil penelitian menunjukkan bahwa lebih banyak suami yang terlibat dalam pengambilan keputusan pada kegiatan domestik sedangkan lebih sedikit istri yang terlibat dalam pengambilan keputusan pada kegiatan publik. Sebagian besar keluarga nelayan hidup diatas garis kemiskinan. Namun berdasarkan pengukuran indikator sosial metrik, sebagian besar keluarga nelayan dikategorikan sebagai keluarga miskin. Analisis lebih lanjut mengindikasikan bahwa perilaku menabung dipengaruhi secara signifikan oleh pendapatan, perilaku kerabat, dan orientasi waktu. Tingkat kesejahteraan keluarga dipengaruhi secara signifikan oleh usia suami, pendidikan istri, pendapatan keluarga, besar keluarga, perilaku kerabat, dan orientasi waktu.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
