Judul: Perilaku Harian Kukang Jawa (Nycticebus javanicus Geoffroy 1812) di Taman Nasional Gunung Halimun Salak (TNGHS) Jawa Barat
Abstrak: Javan slow loris (N. javanicus) is an endangered species however ecological data and information about its life in nature is limited. According to the IUCN, javan slow loris is one of the critical wildlife status (critically endangered) and listed on Appendix I of CITES since 2007. This study aimed to investigate daily activities of N. javanicus and to assess correlation between climate, moon phase and daily activities of javan slow loris in the Mount Halimun Salak National Park (MHSNP) West Java. Behavioral observations was carried out using a modified method of focal time sampling. Principal Component Analysis (PCA) was used to determine the correlation between the climatic aspects and daily activities. Behavioral observations was conducted on two wild adult females. The most dominant of daily activities N. javanicus were travelling (37.9%), feeding (21.8%), active (12.5%) and foraging (12.3%). N. javanicus preferred natural food items such as nectar (79.9%), sap (16.6%), insects (3.0%) and fruits (0.5%). Correlation climate aspect and moon phase of the daily activities N. javanicus was 59.3%. Phases of the moon gave impact mostly on the daily activities. Nycticebus javanicus is a primate lunar phobia or likely to be active in slightly or no light conditions (dark).

Judul: Aktivitas Harian Dan Wilayah Jelajah Kukang Jawa (Nycticebus Javanicus Geoffroy 1812) Di Taman Nasional Gunung Halimun Salak
Abstrak: Kukang jawa (Nycticebus javanicus) merupakan primata endemik Jawa Barat yang termasuk ke dalam kategori Critically Endangered dalam IUCN. Penelitian bertujuan untuk mengidentifikasi aktivitas harian, wilayah jelajah, kondisi habitat dari pemilihan lokasi tidur, dan komposisi vegetasi kukang jawa. Penelitian dilakukan pada bulan Juli sampai September 2014 dengan menggunakan satu individu kukang jawa liar yang telah dipasang radio collar. Aktivitas makan merupakan aktivitas harian dominan pada kukang jawa dengan presentase sebesar 33.23%. Berdasarkan hasil perhitungan menggunakan metode Minimum Convex Polygon (MCP) diperoleh rata-rata luas wilayah jelajah kukang jawa 8.16 ha, sedangkan dengan menggunakan Fixed Kernel (FK) 95% diperoleh rata-rata luas wilayah jelajah kukang jawa 4.13 ha dan dua daerah inti dengan luas 0.5 ha. Jenis tumbuhan yang ditemukan pada analisis vegetasi sebanyak 22 jenis tumbuhan. Kukang jawa menggunakan liana cangkore pada pohon reungas dan pohon kokosan monyet.

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.
