Judul: The influence of land width and land tenure status of farmers international migration
Abstrak: Fenomena migrasi internasional merupakan salah satu fenomena kependudukan yang terjadi di berbagai daerah di Indonesia. Terutama di daerah pantai utara Jawa. Salah satu alasan untuk melakukan migrasi internasional masyarakat pedesaan adalah adanya keterbatasan penguasaan lahan pertanian yang menjadi komponen yang penting dalam melaksanakan usaha pertanian. Tujuan dari penulisan skripsi ini adalah mengetahui dampak luas dan status penguasaan lahan pertanian dalam memengaruhi intensitas migrasi internasional masyarakat petani pedesaan, serta pengaruhnya terhadap perubahan struktur agraria di Desa Karangmulya. Pendekatan yang digunakan untuk menganalisis pengaruh tersebut adalah pendekatan kuantitatif dengan metode survei yang didukung oleh data kualitatif yang relevan. Hasil analisis menunjukan bahwa terdapat hubungan yang lemah antara luas dan status penguasaan lahan di daerah asal terhadap intensitas migrasi. Hal tersebut disebabkan adanya faktor lain yang memengaruhi, yaitu kemudahan akses dan keuntungan yang lebih besar bagi masyarakat untuk melakukan migrasi internasional. Selain itu, migrasi yang dilakukan dapat meningkatkan akses terhadap lahan pertanian di daerah asal.

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.
