Judul: Nilai Ekonomi Total dan Analisis Multistakeholder Hutan Rakyat di Kecamatan Giriwoyo, Kabupaten Wonogiri, Jawa Tengah
Abstrak: Smallholder Forest have economic and ecological functions. The economic function of smallholder forest, such as timber and firewood can be called as tangible values. The ecological functions which are called intangible values are absorbing carbons and retaining waters. The objectives of this research are to identify the actual condition of Giriwoyo smallholder forest, to estimate its economic value, to analyze its institutional management and to formulate recommendations for better management. The method used to identify the actual condition of Giriwoyo smallholder forest is descriptive analysis. The benefits of Giriwoyo smallholder forest are calculated using Total Economic Value (TEV) approach. Institutional management are analyzed using Importance Performance Analysis (IPA). The result of this research shows that Total economic value of Giriwoyo smallholder forest is about IDR 17.622.296.440 per annum. Its management institution seemed quite good because there was clear division of labour. Based on analysis of IPA, the function of farmers in doing a fertilization and the role of government in coordination must be prioritized

Abstrak: Currently various community-based forest resources are found to have been able to save forests from extinction. It's rationale necessitates the need to incorporate social capital in community forest management and timber trade. The research objectives were (1) to identify and assess individual characteristics, elements of social capital and community timber trade patterns, (2) to determine and analyze the relationship between individual characteristics and the elements of social capital as well as community timber trade patterns, (3) to obtain the most appropriate strategy in the management of community forests and timber trade. Data were analyzed descriptively, using Spearman rank correlation, SWOT and QSPM analyses. The individual characteristics of farmers, based on the assessments, were in the medium category. The social capital was at the high level, at which people are generally committed to joint efforts, effective collaboration, collective and institutionalized action, expressing ideas to increase productivity, maximize mutual benefit and positive interdependence. The elements of community timber trade observed were the pattern of sale time, marketing chain and the sale system in three channels. The individual characteristics that were significantly correlated with the elements of social capital were age, formal education, non-formal education, income, and social status.

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.
