Judul: Study of Land-use change for referral of spatial pattern arrangement in the Gedong Wani Production Forest Area, Lampung Province.
Abstrak: According to Law No. 41/1999 regarding Forestry, production forest has principal function of producing timber forest products, non- timber and other environment services. However, it is not found in the Gedong Wani production forest area Lampung province, as the region has grown to become the definitive rural land uses such as residential, farm and forest plantations that do not function as intended. This study aims : (1) to analyze the development of the village in a forest area, (2) to analyze land use and land use changes in the period 2000-2013, (3) to analyze influence of physical factors of land, demography and forest land use policies on land use change in forest area, (4) to predict landuse within a period of 13 years ahead and (5) to formulate policy directives of spatial patterns arrangement of forest area in order to function as intended. The study was conducted in Gedong Wani production forests area in South Lampung and East Lampung regencies. The method was used as follow : (1) to analyze of rural development using schallogram analysis, (2) to analyze land use through interpretation of satellite imagery Landsat 5 TM in 2000 and Landsat 8 TM In 2013, landuse changed analysis through overlay with Geographic Information Systems (GIS), (3) landuse prediction with Cellular Automata approach, (4) to analyze physical aspects of the land , demography and landuse forest policies that influence land use through regression logistic Binner, (5) to formulate refferal of spatial patterns arrangement of forest production area through synthesis of land-use and rural development analysis with consider of utilization and using of forest area according to Act No. 41/1999. The results showed that there were 39 villages in GedongWani production forest area with the highest growth rate in 2011 found in Jati Baru village Tanjung Bintang districts South Lampung regency. Land-use change between 2000 and 2013 show an increase in smallholder plantation and built up area, conversely, a decrease in extent of dry land cultivation and forests. In terms of the physical aspects of the land, demography and landuse forest policy, the factors that influence land use change into dry land cultivation and built up area are land-use forest policy and addition of number of people. Land -use change posibility occurs on land that has borrow-use permits of forest area for industrial and land rights that have been change of forest land for development of the new city of Lampung as well as lands that have not allocated the rights / permits and forest use, while the chances of a change in land use to smallholder plantations occur on Ultisol soil type. Prediction of land use in year of 2026 based on the assumption of behavioral changes in land use in the periode of previous years, showed an increase in smallholder plantations and built-up area, and decrease in dry land cultivation and forest area. Policy directives of spatial patterns arrangement of production forests is to regulate the use of existing land use and the use of appropriate mechanisms of production forest area according to Act No. 41/1999 which adds forest area

Judul: Analisis perubahan ruang terbuka hijau dan strategi pengembangannya di Kota Bandar Lampung:
Abstrak: Development of Bandar Lampung City has the great influenced to the land use changes. Land use conversion commonly happen on Green Open Space (GOS) into other usages. The aims of this research are : (a) to identify GOS change in Bandar Lampung City along the year 2000-2007; (b) to identify GOS needed base on regulation of spatial planning (UU No 26/2007) and number of population; (c) to identify center of GOS change into built up area related to the regional development and the factors that affected the change; (d) to identify divergency of GOS change in RTRW (Public Document of Regional Planning); and (5) to find the strategy to maintain and develop GOS. This research was conducted by Landsat analysis using Geographic Information System (GIS) and combined with Location Quotient Analisys (LQ) to analize GS change. Scalogram and regression analysis used for analize the regional development and the factors that affected the GOS change. The result showed that forest, mixed dry farming, plantation and paddy field decrease of 1.449 Ha (7.35%) in 7 years, since year 2000 to 2007. Meanwhile, built up area increase to 1.218 Ha (6,19%). Based on UU No 26/2007, availability of GOS in Bandar Lampung City are still sufficient (> 30%), it’s about 61.40% (12.110 Ha) from the total area of the city. Analysis of GOS needed based on area found that in subdistrict level at Tanjung Karang Pusat and Kedaton subdistrict insufficient GOS. Based on standard for number of population, Tanjung Karang Pusat, Kedaton and Teluk Betung Selatan subdistrict still in below standard. The changes center of GOS in Bandar Lampung City happen in 63 villages, which are distributed in hierarchy III 79,57 % villages, hierarchy II 16,60% village, and hierarchy I 3,83% village. There are 2 factors that affected GOS change, one is village development index and another is number of population. Land use change from GOS and protection area into built up area was found as deviation of RTRW. The strategy to maintain and to develop GOS depend on the availability and the problem that occur with GOS, so GOS can be developed optimally.

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.
