Judul: Pemodelan Spasial Kesesuaian Habitat Kukang Jawa (Nycticebus javanicus Geoffroy 1812) di Cisurupan Kabupaten Garut
Abstrak: Javan Lorises (Nycticebus javanicus) are nocturnal primates endemic to Java island. Their habitats are primary and secondary forest vegetation, plantation area, and bamboos vegetation. They were categorized as endangered species because of the illegal trading and their habitat degradation. Spatial modelling was one of many kinds of Javan loris insitu conservation efforts of the especially in Cisurupan Garut. The habitat suitability factors of Javan lorises were altitude, slope, NDVI, surface temperature,distance of sleep trees and feed density. The Javan lorises habitat suitability based on PCA was Y = (1.952*altitude) + (1.952*slope) + (1.028*NDVI) + (1.952* surface tempe- rature) + (1.347* distance of sleep trees) + (1.952*feed density), with validation value of 100%. Total area habitats Javan lori is 7843,02 ha. As many as 534.55 ha of their habitat were categorized into low suitability,2968.11 ha categorized into medium suitability, and 3971.87 ha of its were categorized into high suitability.

Judul: Habitat, populasi, dan sebaran kukang jawa (Nycticebus javanicus geoffroy 1812) di Talun Tasikmalaya dan Ciamis, Jawa Barat
Abstrak: Javan slow loris is an endangered primate that naturely inhabits in some agroforestry garden namely talun in West Java. This study aimed to determine habitat preferences and to estimate population number. Data collection was conducted during April-December 2008 in four villages in Tasikmalaya District and one village in Ciamis District. The methods used to collect vegetation data were belt transect and nested plot, and method to collect javan slow loris densities was line transects. In total ten observed-belt transects showed that habitat preferences of javan slow loris was talun at two main phases: II (talun kebun or more opened vegetation) and III (talun sempurna or closely secondary forest structure). Dominant vegetation in talun habitat indicated by Important Value Index (IVI) proofed to played role as javan slow loris's food source, sleeping site, and habitat of prey and gave benefits the owner of talun for their financial investment. The greatest IVI of vegetation in the sites are Gigantochloa sp., Paraserianthes falcataria (L) I. C. Nielsen, and Arenga pinnata Merr. Ten line transects were used during day and night, therefore the population estimate in each village was 93.67 individuals at Sukamaju which has 4.43 km2 of habitat representative area, 173.79 individuals at Raksajaya (3.23 km2), 119.78 individuals at Kawungsari (6.96 km2), 58.83 individuals at Sarimanggu (3.48 km2), and 20.45 individuals at Sukakerta (1.39 km2). Javan slow loris tends to adapt to the condition of talun habitat, as a result their distributions abundance in range between 220-985 m height above sea level.

Judul: Pemanasan Sekunder Reaksi Fusi Plasma dengan Menggunakan Radio Frequency
Abstrak: Plasma merupakan bentuk ke-empat dari materi setelah padat, cair dan gas yang terbentuk dari proses ionisasi gas. Plasma dapat digunakan dalam reaksi fusi, yaitu reaksi penggabungan dua inti atom ringan menjadi inti atom yang lebih berat sambil melepaskan energi. Untuk mendapatkan energi dari reaksi fusi, inti yang akan direaksikan harus dipanaskan pada temperatur yang sangat ekstrem tingginya. Salah satu cara agar dapat mencapai kondisi ini adalah memberikan pemanasan tambahan atau pemanasan sekunder kepada plasma dalam reaksi fusi tersebut. Nilai daya serap rata-rata ion Deuterium yang sesuai dengan selang nilai daya dari data ITER adalah daya yang menggunakan frekuensi 50 MHz sampai dengan 60 MHz. Dengan menggunakan frekuensi 60 Hz diperoleh nilai daya rata-rata yang diserap sebesar 1,235.10-12 W.
