Judul: The Role of Youth in Agricultural Empowerment Programme for Young Farmers (Case Study of Merdesa Farm, in Cikarawang  Village, Dramaga District, Bogor Regency)
Abstrak: Penelitian ini bertujuan mengkaji peran pemuda yang menjadi peserta dalam program pemberdayaan pertanian untuk petani muda dengan memperhitungkan variabel faktor internal dan eksternal. Fenomena ini diteliti melalui delapan pemuda yang terlibat dalam Kebun Merdesa di Desa Cikarawang, Kecamatan Dramaga, Kabupaten Bogor sebagai peserta program pemberdayaan. Faktor internal terdiri atas tingkat pendidikan, pengalaman organisasi, pengalaman bertani, penguasaan teknologi, dan penguasaan tanah. Sementara itu, faktor eksternal meliputi dukungan program pemberdayaan petani muda dan infrastruktur teknologi bertani dari luar program Kebun Merdesa. Adapun peran pemuda yang diidentifikasi dibagi menjadi peranan motivator, fasilitator, dan mobilisator. Metode penelitian yang digunakan adalah pendekatan kualitatif yang didukung oleh pendekatan kuantitatif. Penelitian kualitatif dilakukan melalui observasi lapangan dan wawancara mendalam. Adapun penelitian kuantitatif dilakukan melalui survei dengan instrumen kuesioner dan hanya bersifat pendukung tanpa melakukan analisis hubungan antar sejumlah variabel secara statistik. Hasil tabulasi silang menunjukkan bahwa sebagian besar faktor internal (tingkat pendidikan, pengalaman berorganisasi, dan penguasaan tanah) dan satu faktor eksternal (dukungan infrastruktur bertani) memiliki hubungan dengan peran pemuda. Sementara itu, faktor internal berupa pengalaman bertani dan penguasaan teknologi serta faktor eksternal berupa program pemberdayaan pertanian dari luar Kebun Merdesa tidak berhubungan dengan peran pemuda. Data kualitatif menunjukkan bahwa ada faktor-faktor lain yang ternyata memengaruhi peran pemuda, yakni umur peserta, modal sosial, relasi kuasa dengan pengelola Kebun Merdesa, kemampuan interpersonal, dan lama bergabung di Kebun Merdesa.

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.
