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 Penyediaan Hijauan Pakan untuk Sapi Potong di Kabupaten Sumba Timur Menggunakan Citra Landsat
Abstrak: Citra Landsat is one of the remote sensing technology product that provides information on land cover and provide facilities of performs analyses planning and provision forage in one area. The development of the region can use the direction of land use in determination of provision forage fodder. The purpose this research is to plan the provision of forage using land use maps as a reference direction to fulfill the needs of cattle feed and calculate the potential production capacities of land and livestock in East Sumba. This study uses Nell and Rollinson (1974) for the processing of data, secondary data, primary data and Landsat image map direction then planning provision is made under the direction of forage crops to be grown. District Pandawai beef cattle population programs cow calf operation (CCO) by 4 816.32 AU, village breeding center (VBC) as much as 71 AU and village farming center (VFC) as much as 166 AU. District Lewa CCO generated by 8 566.97 AU, VBC and VFC as many as 518 AU and 1 210 AU. District Nggaha Ori Angu generated as much CCO 6 028 AU, VBC as much as 780 AU and VFC as much as 1 820 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.
