Judul: Fire Control System in Gunung Walat Education Forest, Sukabumi, West Jawa
Abstrak: Kebakaran hutan terjadi setiap tahun di Indonesia dengan frekuensi, intensitas, dan luas areal terbakar yang berbeda. Hutan Pendidikan Gunung Walat (HPGW) termasuk ke dalam Kawasan Hutan dengan Tujuan Khusus (KHDTK) yang dikelola oleh Fakultas Kehutanan dan Lingkungan IPB. HPGW merupakan salah satu kawasan hutan di Jawa Barat yang hampir setiap tahunnya mengalami kebakaran. Penelitian ini bertujuan mengidentifikasi, mendeskripsikan, dan menganalisis faktor penyebab terjadinya kebakaran hutan, tingkat kerawanan kebakaran hutan di HPGW berdasarkan curah hujan, serta sistem pengendalian kebakaran hutan yang diterapkan di HPGW. Metode analisis data yang digunakan adalah deskriptif kualitatif dengan mendeskripsikan semua fakta yang diperoleh. Pembukaan lahan dengan membakar oleh masyarakat menjadi penyebab utama kebakaran hutan di HPGW. Hasil analisis curah hujan untuk menentukan tingkat kerawanan kawasan terhadap kebakaran menunjukkan tingkat kerawanan yang rendah dengan nilai 2805,5 mm/tahun. Bahan bakar potensial di kawasan ini antara lain, tegakan jenis pinus dan agatis serta serasah daun pinus. Sistem pengendalian kebakaran hutan di HPGW terdiri atas empat komponen yaitu pencegahan, pra pemadaman, pemadaman, dan penanganan pasca kebakaran hutan., Forest fires occur every year in Indonesia with different frequency, intensity, and area burned. Gunung Walat Educational Forest (HPGW) is included in the Special Purpose Forest Area (KHDTK) managed by the Faculty of Forestry and Environment, IPB. It is one of the forest areas in West Java that experiences forest fires almost every year. The purposes of this research are to identify, describe, and analyze the factors that cause forest fires, the potential for fuel, the level of forest fire vulnerability in the HPGW based on rainfall, and the forest fire control system implemented in the HPGW. Data analysis method is descriptive qualitative by describing all the facts obtained. Land clearing by burning by people is the main cause of forest fires in HPGW. The results of the rainfall analysis to determine the area's vulnerability to fire showed a low level of vulnerability with a value of 2805.5 mm/year. There ara two species that can be potential fuels in this area, namely pine and agatis species, and also pine leaf litter. The forest fire control system in HPGW consists of four components, namely prevention, pre-extinguishing, extinguishing, and post-forest fire management.

Judul: Community Participation in Forest Fire Control at BKPH Pangalengan, KPH Bandung Selatan
Abstrak: Kebakaran hutan merupakan permasalahan yang sering terjadi di Indonesia. Penyebab terjadinya kebakaran hutan terdiri dari dua faktor yaitu faktor alami dan faktor ulah manusia baik disengaja ataupun tidak disengaja. Penelitian ini bertujuan untuk menganalisis upaya pengendalian kebakaran hutan melalui partisipasi masyarakat di BKPH Pangalengan, KPH Bandung Selatan. Data yang digunakan berupa data primer dan data sekunder. Analisis data dilakukan dengan metode deskriptif kualitatif yaitu dengan cara mendeskripsikan secara menyeluruh data yang diperoleh selama proses penelitian. Kejadian kebakaran hutan dalam kurun waktu 2015-2019 terjadi pada tahun 2018 dengan frekuensi 2 kali dan total luas lahan yang terbakar sebesar 4 Ha. Bentuk partisipasi masyarakat di BKPH Pangalengan adalah adanya Kelompok Tani Hutan (KTH) dan Lembaga Masyarakat Desa Hutan (LMDH). Berdasarkan data yang diperoleh terdapat 14 LMDH yang tersebar di setiap RPH yang berada di BKPH Pangalengan. Partisipasi masyarakat dalam pengendalian kebakaran hutan di BKPH Pangalengan sangatlah tinggi., Forest fires are one of a problem that occurs in Indonesia. The causes of forest fires consist of two factors, i.e. natural factors and man-made factors, whether intentional or unintentional. This research aims to analyze forest fire control through community participation at BKPH Pangalengan, KPH South Bandung. This research uses primary and secondary data. The data were analyzed using a qualitative descriptive method, which mean by thoroughly described all the data that obtained during research process. Forest fire incidents in the period of 2015-2019 occurred in 2018 with 2 incidents and the total burned area was 4 hectares. The form of community participation in BKPH Pangalengan is the existence of the Forest Farmers Group (KTH) and the Forest Village Community Institution (LMDH). Based on data, there are 14 LMDHs scattered in each RPH located in BKP Pangalengan. Community participation in forest fire control at BKPH Pangalengan is very high.

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.
