Judul: Pola Ekologi Owa Jawa Liar (Hylobates moloch) di Pulau Jawa, Indonesia: Efek Faktor Lingkungan
Abstrak: The geographical (latitude, longitude, and altitude) and environmental variables (rainfall and temperature) would be important constraints on forest structure, food abundance, other resources’ distribution and availability. These can affect dietary habits, behavior, and dayly travel distance. This study aims to examine environmental determinant(s) of behavioral and social aspects of Javan gibbons through meta-analysis. This study compiled previous publications about gibbons through database searching. Employed statistical analyses were Spearman’s rank correlation and Kruskal-Wallis tests. The results showed that there were no significant correlations between geographical/environmental variables and behavioral/social aspects, except for relationship with latitude and number of animals per group. This study also found no significant differences in behavioral/social aspects among forest types.

Judul: Studi Lokomotor dan Postur Per Aktivitas Owa Jawa (Hylobates moloch Audebert, 1798) di Taman Nasional Gunung Halimun Salak.
Abstrak: Gunung Halimun Salak National Park is the largest mountainous tropical rainforest remaining in Java island and it is an important habitat for the preservation of javan gibbon (Hylobates moloch Audebert 1798), an endemic primate in Java island. A study of posture and locomotion of javan gibbon is needed considering within their daily activities, javan gibbon using different spatial habitat structure and therefor the information is important as reference to make a better decision in conserving habitat and population of javan gibbon based on aspect of behavioral and ecology. This study was conducted in an area of Cikaniki – Citalahab, Gunung Botol resort for one month (June – July 2012). Equipments used in the study were range finder, binoculars, phi bands, compass, camera, stationery and stopwatch as a tools. Data were collected from two groups of well-habituated javan gibbon, named group A and B, by using scan and focal animal sampling in order to get collected behavioral data. Profile diagram of the habitat was also developed. To determine home range, convex polygon and fixed kernel 95% were applied. The mean active period of javan gibbon was 9 hours at 07.35 am – 4.50 pm and dominated by resting activity for 48.18%. The dominant locomotor type during their active period was brachiation with frequency and duration of 46,07 – 79,33% and 11,52 – 15,26 hours. Meanwhile the percentage of sitting posture type with frequency and duration was 72,78% - 84,12% and 11,12 – 19,04 hours. There was 24 species of trees used as locomotion mediums and 16 trees for postures. The most dominant species was puspa (Schima wallichii) with most dominant family was from family Fagaceae. The percentage of crown covers for the two groups was 62.2%. Alleged average daily range during the observation time of 641.96 m group A while group B of 1278.18 m. Calculations with FK 95% giving an average cruising area of 50.27 ha, while the 100% MCP method gives an average cruising area of 24.38 ha. Analysis of the Digital Elevation Model (DEM), wide ranges of the study group had a mean - average of 25.65 ha for the analysis of the MCP and 53.25 ha for FK analysis results with 95%. Result of posture and locomotor study could be used as consideration to design of ex situ conservation area of javan gibbon beyond, that includes also habitat enrichment. Map of the daily movements and home ranges of Javan gibbon can be used as supporting data for the object ecotourism attractions of special interest, education and research. Also, it can be a reference park managers in monitoring the presence of a controlling Javan gibbon habitat
