Judul: Simulasi penyediaan pakan di kawasan bomberay provinsi papua barat menggunakan peta arahan penggunaan lahan
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: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
