Judul: Faktor Penyebab dan Upaya Pengendalian Kebakaran Hutan di Perhutani KPH Indramayu
Abstrak: Forest fire is one of the obstacle in forest which often occurred in Indonesia. Cause of forest fire consist two factors: natural and human factors. Efforts of forest fire control nowadays more emphasized with community involvement. The objective of this research was to examine the causes of forest fire also the efforts of forest fire in KPH Indramayu. This research was done by filling the questionnaire based on the results of the interview. The results of this research revealed that one of the factor which caused forest. Land clearing by the community with the burning system still contain risk which caused forest fire although the community use the controlled burning system, and it should be emphasized to all parties that cigarette is not the main cause of forest fire. Efforts of forest fire control in BKPH Sanca includes prevention, suppression, and extinguishing, but the implementation is not optimal yet.

Judul: Faktor Penyebab dan Upaya Pengendalian Kebakaran Hutan di KPH Malang Perum Perhutani Divisi Regional II Jawa Timur
Abstrak: Kebakaran hutan merupakan salah satu gangguan hutan yang sering terjadi di Indonesia dan dapat menimbulkan banyak kerugian dari berbagai aspek sumberdaya hutan. Upaya pengendalian kebakaran hutan saat ini telah banyak dilakukan dan ditekankan dengan melibatkan masyarakat sekitar hutan. Tujuan penelitian ini adalah untuk mengkaji faktor penyebab dan upaya pengendalian kebakaran hutan di KPH Malang. Penelitian ini dilakukan dengan pengisian kuisioner dan wawancara kepada masyarakat. Setelah itu data di analisis secara deskriptif. Berdasarkan hasil penelitian diketahui bahwa kebakaran hutan di KPH Malang sebagian besar disebabkan oleh kegiatan masyarakat dalam melakukan pembersihan lahan. Tindakan pencegahan kebakaran hutan yang telah dilakukan berupa sosialisasi/penyuluhan, pemasangan papan peringatan, dan pembuatan sekat bakar. Sarana dan prasarana dalam kegiatan pemadaman kebakaran masih sangat minim. Penanganan pasca kebakaran yang dilakukan dalam penegakan hukum masih terkendala dalam penangkapan pelaku pembakaran hutan.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
