Judul: Sistem Peringatan Dini dalam Kegiatan Pencegahan Kebakaran Hutan di KPH Kuningan, Jawa Barat
Abstrak: Kebakaran hutan memberikan dampak negatif yang cukup besar oleh karena itu diperlukan suatu tindakan pencegahan sejak awal. Salah satu kegiatan pencegahannya yaitu menentukan daerah rawan kebakaran hutan. Tingkat persepsi masyarakat berdasarkan penelitian di beberapa desa di KPH Kuningan terhadap sistem peringatan dini tergolong tinggi untuk Desa Cihanjaro, tergolong sedang untuk Desa Simpayjaya dan tergolong rendah untuk Desa Kawungsari. Menurut aksesbilitasnya, Desa Kawungsari memiliki akses paling tinggi dengan hutan. Ada beberapa variabel penyebab kebakaran hutan antara lain : jarak antara pemukiman penduduk dengan hutan, aksesbilitas menuju hutan, dan potensi daerah terjadi konflik. Penentuan daerah rawan kebakaran hutan dapat dilihat melalui tingkat persepsi masyarakat terhadap keberadaan KPH Kuningan dan sistem peringatan dini dalam kegiatan pencegahan kebakaran 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.
