Judul: Persepsi dan Perilaku Masyarakat Desa Cipaganti terhadap Kukang jawa (Nycticebus javanicus)
Abstrak: Perceptions of the Javan slow loris are the responses to, and understanding of this Javanese prosimian. It captures the senses sight, hearing, smell, feeling and reasoning through a mental process, which will be the motivation, strength, encouragement or presseure to perform a certain behavior. This study aims to acquire knowledge of the perception of the local community in Cipaganti village regarding the Javan slow loris and to determine the relationship between the perception of the villagers of Cipaganti and their behaviour towards the javan slow loris. Perceptions in Cipaganti village as a whole can be seen as appropriate behaviour of the Javan slow loris, the Javan slow loris has benefits, and has economic value. Furthermore they believe in various traditional myths surronding the slow loris and perceive it as dangerous. Respondents generally do not approach a slow loris when sighted and assume that if humans not disturb these prosimians, the javan slow loris will not interfere with or even attack humans.

Abstrak: The Javan slow loris (Nycticebus javanicus) is a slow moving nocturnal prosimian primate. Javan slow lorises are considered Critically Endangered by the International Union for the Conservation of Nature (IUCN 2013), as well as being listed in Appendix I of Convention on International Trade in Endangered Species (2007). To date, there is limited source information available regarding wild loris ecology and behavior. In this study, home range areas and use space of wild javan slow loris was carried out in Mount Halimun-Salak National Park, in Bogor, West Java, Indonesia. This study aims to measure home range size and to analyze activity budgets in natural forest conditions. Kernel Home range methods were used to analyze home range areas, while Point Centered Quarter methods were used to collect habitat data, and five minute Instantaneous-Focal Animal Sampling was used to observe and record behavioral data. The observed lorises were two adult females, one of which (Individual I) was pregnant. Analysis showed contiguous home range sizes of 5.43 hectares and 5.58 hectares for Individuals I and II respectively, as well as a core home range area of 1.77 hectares and 1.60 hectares. These home ranges were larger than that reported in Malaysian Nycticebus coucang. Behavioral analysis showed that daily activities were dominated by travel, feeding, active, and foraging, which took place primarily in the lower canopy stratum (2 – 15 m), whereas sleeping typically occurred in the medium canopy stratum height (15 – 22 m). The use of space of javan slow loris correlated with height, substrat, contact, and size of branch. Javan slow loris preferred heights positions (5 – 7 m), and the size of a small twig branch categories. Javan slow loris preferred to use kaliandra (Calliandra calothyrsus), bungbuai (Plectomia elongata), and kisampang (Evodia latifolia) as foraging site and sleeping tree.

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.
