Judul: Strategi Pengendalian Kebakaran Hutan dan Lahan di Taman Nasional Rawa Aopa Watumohai dengan Pemanfaatan Pemodelan Spasial.
Abstrak: Rawa Aopa Watumohai National Park (TNRAW) is one of the most important conservation areas in Indonesia which has unique species in Wallacea region, and an international status as a RAMSAR Site. Unfortunately, TNRAW has been disturbed by wildfire that could potentially degrade functions. The objectives of this study were (1) to analyze the appropriate factors that influenced the vulnerability of forest fires in TNRAW and the surrounding areas, (2) to optimize forest fires management in TNRAW through early warning and spatial modeling, (3) to formulate strategic direction to control forest fires in TNRAW. This research used the CMA (Composite Mapping Analysis) method. Based on the analysis of the 13 variables associated fuels and ignitions, it was formed 9 variables that built the hotspots density model in the study area, they were the average monthly temperature, elevation, slope, level of income, population density, land cover, the buffers of rivers, the buffers of mangrove / marine and the buffers of district centers. The factors influenced spatially vulnerability of the forest fires in the study area were socio-economic (regional income) and land cover. On the other hand, the rainfall intensity influenced temporally frequency of wildfires. Best composite model had a determination coefficient of 25.8 % and formed a polynomial model. Three classes of fires vulnerability grouped by Arc GIS 9.3 based on summary mean and standard deviation, ie low vulnerability 815.32 km² (77.51 %), middle class 92.74 km² (8.8 %) and high vulnerability 137.14 km² (13.04 %). The widest class of high vulnerability was the buffer zone of 104.86 km² (9.97 %), and the core zone just only 2.1 km² (0.2 %). According to the spatial model, the effective forest fires management needed to consider socio-economic and land cover. The priority of the forest fires management needed to be focused at the core zone and the buffer zone from the foot of Watumohai Mountains to savanna near mangrove which high vulnerability for wildfires. The chosen strategy based on Quantitative Strategic Planning Matrix (QSPM) method by score of 5.87 was the threats analysis and diversification of forest fire control method, devided into preventif and repressive methods, such as socialization, promotion, infrastructure development, law enforcement and fire suppression.

Judul: Analisis Pola Sebaran Titik Panas dan Pemodelan Spasial Kerentanan Kebakaran Hutan dan Lahan di Kabupaten Kapuas, Kalimantan Tengah
Abstrak: Land and forest fires in Indonesia become a serious problem since 1982/1983. Kapuas District is one of districts in Central Kalimantan which often experiences land and forest fire. Aim of this research is to analyze the distribution of hotspot in Kapuas District, to identify the driver factors which cause land and forest fire, to build spatial modeling and to map land and forest fire vulnerability index in that area. A Composite Mapping Analysis (CMA) method was used to build spatial modeling. The maximum distribution of hotspot during 2005 to 2012 occured in 2006 and 2009, and it was estimated due to the influence of El-Nino, so the intensity of the land and forest fire increased. Dominant driving factors of land and forest fire vulnerability from the highest to the lowest are depth of peat, distance to central village, land use/cover, road distance, and river distance. Depth of peat is a factor that has a higher influence than others factors. The best spatial modeling for vulnerability of land and forest fire is a model with 5 factors, those are depth of peat, distance to central village, land use/cover, road distance, and river distance. The result of land and forest fire vulnerability mapping showed that high to the very high vulnerability index of the Mantangai sub-district in very large region.

Judul: Respon Sel Leydig Dari Mencit Neonatal Terhadap Hcg Selama Kultur In Vitro.
Abstrak: Sel Leydig merupakan sel penghasil hormon testosteron pada hewan jantan. Berdasarkan tingkat kematangan, populasinya terbagi menjadi sel Leydig fetal dan sel Leydig dewasa. Hormon human chorionic gonadotropin (hCG) adalah salah satu faktor yang memengaruhi proliferasi dan diferensiasi pada sel Leydig dewasa, tetapi belum diketahui pengaruhnya pada sel Leydig fetal. Penelitian ini bertujuan untuk menjajaki respon sel Leydig fetal terhadap penambahan hCG pada kultur in vitro dengan menggunakan sel Leydig yang diisolasi dari mencit neonatal. Sel Leydig diisolasi dari mencit neonatal umur tiga hari, dikultur in vitro selama enam hari, dan diberi perlakuan dengan dan tanpa penambahan hCG. Data yang dievaluasi berupa tingkat proliferasi (population doubling time, PDT) dan jumlah sel yang mengekspresikan keberadaan enzim 3β-HSD. Hasil penelitian menunjukkan bahwa penambahan hCG pada kultur in vitro sel Leydig dewasa meningkatkan proliferasi sel, sebaliknya pada sel Leydig fetal menurunkan proliferasi sel. Penambahan hCG tidak memengaruhi persentase jumlah sel Leydig dari mencit neonatal yang mengekspresikan enzim 3β-HSD. Dapat disimpulkan bahwa sel Leydig fetal dari mencit neonatal memiliki respon yang berbeda dengan sel Leydig dewasa terhadap penambahan hCG secara in vitro.
