Judul: Potensi Kebakaran Hutan di KPH Bogor Perum Perhutani Unit III Jawa Barat dan Banten
Abstrak: The potential of forest fire can be studied based on forest fire controlling and source of forest fire that is human activity also rainfall. The objectives of this research are to analyze the level of vulnerability forest fire based on rainfall rate from 5 years recently, to study the source of forest fire and analyze the efforts of forest fire controlling in KPH Bogor. The result showed that the average of yearly rainfall rate on recent 5 years is 2 545 mm. It can be categorized into not prone toward forest fire. The potential of forest fire that caused by land clearing was low because it was controlled burning applied by the society. The potential of forest fire that caused by social conflict was quite high due to lack of good relations between KPH Bogor and the society. Less on information about socialization program and less on attention toward the existence of warning board is a ineffective forest fire controlling.

Judul: Potensi kebakaran hutan di KPH Kuningan Perum Perhutani Jawa Barat
Abstrak: Potensi kebakaran hutan dianalisis berdasarkan kegiatan pengendalian kebakaran hutan, sumber penyebab terjadinya kebakaran hutan yaitu aktivitas manusia dan serta curah hujan. Tujuan penelitian adalah untuk menganalisis upaya pengendalian kebakaran hutan, mengkaji sumber penyebab terjadinya kebakaran hutan dan menganalisis tingkat kerawanan terjadinya kebakaran hutan berdasarkan curah hujan 5 tahun terakhir di KPH Kuningan. Hasil analisis data menunjukkan tingkat kerawanan kebakaran di KPH Kuningan berdasarkan data curah hujan pada 5 tahun terakhir (2010-2014), yaitu 2 503.8 mm termasuk tidak rawan terhadap kebakaran hutan. Potensi kebakaran hutan di KPH Kuningan karena kegiatan pembersihan lahan oleh masyarakat tergolong rendah sebab masyarakat telah menerapkan sistem pembakaran terkendali dan akibat konflik sosial cukup tinggi akibat hubungan antara masyarakat dengan KPH Kuningan kurang terjalin dengan baik. Kurang diperhatikannya keberadaan papan peringatan dan rendahnya informasi mengenai penyuluhan kepada masyarakat merupakan bentuk belum optimalnya upaya pengendalian.

Judul: Optimization of Alginate-Chitosan Microcapsules Formation for Leydig Cells Encapsulation
Abstrak: Hypogonadism is a clinical condition characterized by low concentrations of testosterone. It is caused by malfunction of Leydig cells in producing testosterone. Encapsulation method will protect the transplanted cells from the immune system rejection. The aims of this study was to optimize the formation of microcapsules for Leydig cells encapsulation. The microcapsules were made of alginate and chitosan as the first and the second coating agents, respectively. The result showed that the minimum concentration of alginate was 1.5% (w/v) with a viscosity of 33.8 cPs, resulted spherical microcapsules with diameters of 230-270 µm. The optimum concentration of chitosan as the second coating agent was 0.5% (w/v), resulted spherical microcapsule with mechanical stability in 4 hours. Leydig cells can be trapped inside the capsule with a density that proportional with concentration of cells used in the encapsulation.
