Judul: Kontribusi Pengelolaan Hutan Rakyat Terhadap Pendapatan Rumah Tangga Petani dan Analisis Kelayakan Usaha Hutan Rakyat. (Studi di Desa Babakanreuma, Kecamatan Sindangagung, Kabupaten Kuningan, Propinsi Jawa Barat)
Abstrak: According to Hardjanto (2000), income of community forest farmers in Java are still positioned as a by product and incidental. Range of income is not more than 10 % of total revenue and sought simply. It shows that the contribution of community forest have not become the foundation of households subsistence, so it is necessary to conduct a study about how is the contribution of community forests management to total household income and it’s feasibility, especially in the Village Babakanreuma, District Sindangagung, Kuningan Regency, West Java Province. The purpose of this study was to identify the system of community forests management and marketing, knowing the contributions community forests management to households total income as well as examine the linkage of effectiveness of community forests area to the households total income and to determine the feasibility of it’s businesses. Determination of the respondents conducted using stratified random sampling method in which the respondents were 36 people obtained from the slovin formula. This study uses a qualitative approach that conducted by survey method using questionnaire and supported by quantitative techniques. The results shows that the contribution of community forests management to the households income has been very visible, reinforced by the magnitude of the contribution value that become higher and increasing in strata. So that the farmers land area of community forest significantly affected their household income. From the data obtained, in 1st strata , the resulting contribution is Rp. 2,208,333.00 per year (7.79%), 2nd strata is Rp 3.800.000,00 per year (11.98%), and 3rd strata is Rp 5.500.000,00 per year (13.00%). Management of community forests is feasible to run on all three strata. These statements are based on the amount of NPV (Net Present Value) that is not negative, BCR (Benefit Cost Ratio) is greater than one and the IRR (Internal Rate of Return) is greater than the prevailing rates. NPV values in strata I, II and III is Rp 6.378.880,00; Rp 14.134.803,00 and Rp 3.985.918.00. Community forests management systems at the sites are still modest. The harvesting is still based on needs and not according to the Sengon plant cycle which is the staple in this village. The timber marketing is only done by a contract system or the middleman (tengkulak) / buyer and furthermore become the responsibility of the middleman / buyer it self.

One alternative solution to this problem is to plant forests construction in forest areas that are not productive especially outside Java or other alternatives is the construction of the community forest in the island of Java also outside of Java island. The result of the community forest development activities in addition to the ecologically can support the environment, can also be produced folk wood currently has evolved into a commodity which has a pretty good economic value and perceived by the public that this effort can provide extra income. The community forest as an approach to development of forestry is also prolific on environmental sustainability and an increase in people's income, so that needs to be developed with the better, so as to provide a high timber production and improve the welfare of farmers, while paying attention to power support and function of forests. This research aims to understand further the characteristics and role of the community forest in the Pasir Madang region, particularly from aspect of the community forest’s role against the welfare of the family. This research studies economic condition community forest farmers through the calculation of the balance of the income and spending the community forest farmer families. Further this research examines the contribution of community forest against the peasant household family income and identifying the motivation of farmers in community forest management. Data collected through interview of selected respondens of community forest farmers by using purposive sampling method. Additional information collected through literature studies on secondary data sources from a variety of related government agencies.

Based on these studies it is known that most of the people in the village of Pasir Madang managed using agroforestry systems. The community forest in the Pasir Madang village serves as the public savings which can be harvested when the farmer needed the money in relatively large amounts and in urgent circumstances. A pattern of harvesting as it is known in terms of as a “tebang butuh” system. The community forest farmer respondents on site research mature majority in the range of 41-50 years old.

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.
