Abstrak: Model Pengambilan Keputusan Denah Pohon (MPKDP) merupakan salah satu cara yang baik untuk menganalisa suatu keputusan. Pada dasarnya MPKDP adalah serangkaian hubungan yang logis antara berbagai alternatif yang dihadapi, berbagai kriteria keputusan dan macam keputusan berupa tindakan menerima atau menolak. Prosedur MPKDP yang mudah dan sederhana dipandang cocok densan jalan pikiran para peternak di pedesaan.

Judul: Kajian Pengambilan Keputusan Pemilihan Jenis Pohon dalam Pengelolaan Hutan Rakyat (Kasus di Desa Bojonggedang, Kecamatan Rancah, Kabupaten Ciamis)
Abstrak: The development and management of community forests in fact now is facing some problems. One of them is related to the selection of seed. The seeds that farmers can get, have modest quality. On the other hand, the choice of good quality tree is determined by the quality of the good seed. In addition to seed selection in community forest management, we should also consider how the farmers run their community forests, therefore this study aims are: 1) to explain the conditions of community forest management at the study site, and 2) to describe the considerations of the tree species which planted by farmers. This study takes place at Bojonggedang Village, Rancah Sub District, Ciamis Regency. The method for selecting respondents is purposive sampling method, with total respondents are 30 peoples. The results of this study indicate that the process of forest management by farmers are: 1) preparation of land, 2) planting, and 3) maintenance with undetermined frequency. Farmers are not doing harvesting activities by themself, they submitted on middlemen for both logging and timber transportation. Processing of forest products by farmers only for personal consumption, not for sale. Economic consideration is a primary consideration in determining the type of tree seed that will be planted. It can be seen from the factor type of seed that produce faster; easier access to markets; and the stability of the selling price of these types.

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.
