Abstrak: Citra Landsat is one of the remote sensing technology that provides information on land cover and provide convenience in analyzing the planning and development of a region. The concept of integrated farming agropolitan Bomberay Region utilize this program to describe the potential that exists in this area and making it easier to know what commodities are in any area that can be optimized for use used as raw material feed, which will increase the population of livestock in the region. The results of landing map Bomberay making the region is divided into five clusters that are shared by top soil as reference direction of development.This planning optimizes the use of commodities that contained in the Bomberay such as corn, waste corn, silage corn, rice, rice bran, rice waste, cassava, cassava waste, cassava, potato tubers, potato tuber waste, palm kernel cake, palm oil sludge, palm fiber, conservation areas, perennial crops and pastures. Based on the use of commodity contained in each region cluster, in Cluster 1 can be generated cow calf operation (CCO) 66.871,029 as livestock unit/animal unit (a.u), village breeding center (VBC) 402,321 as livestock unit/animal unit (a.u) and village farming center (VFC) as 938,748 units of livestock (a.u). Cluster 2 can be generated CCO 32.278,03 as a.u, VBC 557,745 as a.u, VFC 1.301,405 as a.u. In Cluster 3 can be generated CCO 17.844,896 as a.u, VBC 246,726 as a.u and VFC 575,694 as a.u. Cluster 4 produces CCO 50.830,94 as a.u, VBC 1.685,041 as a.u and VFC 3.931,763 as a.u. In Cluster 5 produced 8.615,923 CCO as a.u, VBC 1.986,038 as a.u and VFC 4.634,089 as a.u. Total CCO generated in the Bomberay region amounted to 176.440,819 a.u, VBC 4.877,871 a.u and VFC as much as 11.381,7 a.u.

Judul: Perencanaan pengembangan peternakan sapi potong di Distrik Kebar Papua Barat menggunakan peta arahan penggunaan lahan
Abstrak: Districk Kebar is an area in Papua Barat. Districk Kebar has land use map that can used for made a plann to developed livestock. The land use map made by Pusat Penelitian dan Pengembangan Tanah dan Agroklimat. The map used as reference. The results of calculation showed that Districk Kebar can carrying 72.987 Animal Unit (AU). Metode was used in this research was based on potential productions of plants and potential carrying capacity of calf. Material of research used were landset map and microsoft excel. In this place can be developed livestock. The result showed that potential production of plants in Kebar can provided forage for CCO are 60.712 AU, VBC are 3.683 AU, and VFC are 8.593 AU.

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.
