Judul: Integrasi Neraca Tegakan dan Karbon ke Dalam Perhitungan Produk Domestik Regional Bruto Sektor Kehutanan Kabupaten Blora
Abstrak: Forestry sector plays an important role in the economic of Blora Regency.During 2003-2010 period, this sector made significant contribution to the regional economic in term of income, average 14,48% of Gross Regional Domestic Product (GDRP). This figure doesn’t reflect the true contribution of forest resource to regional income and wellbeing because this measure excluded the depletion of the resources to generate the amount of value of product as stated in conventional account using standart and existing accounting framework. The main objective of this study is to develop and use a forest resources accounting framework to correct indicator of economic performance derived from the System of National Account for the true contribution of forestry sector GRDP in Blora Regency, Central Java Province. This study address two components of value creation in forest: timber production and carbon storage. To estimate the value of timber assetss this study applied two valuation methods: the net price and El Serafy user cost methods. The valuation of benefit of forest for carbon sequestration in this study using the damage cost approach, that’s the estimation of the global damage from climate change averted by reducing. The study showed that accounting for net accumulation of timber and carbon stock in forested land was approximately 20,24% of contribution from forestry sector to GRDP during 2003-2010 period. By including the value of timber and carbon depreciation, forestry sector’s share was corrected about 2,87% lower than conventional account.

Judul: Kontribusi Sektor Kehutanan terhadap Ekonomi Kabupaten Sukabumi
Abstrak: Conventionally, the role of forestry sector in the district of Sukabumi is indicated by its contribution to the Regional Gross Domestic Product (RGDP). However, gross value added that generated from timber industry was not taken into account. This value was included into manufacturing sector. This situation undermined the role of the forestry sector. The objectives of this study are to calculate the contribution of the forestry sector to the RGDP of Sukabumi and to determine policy alternative priority that improve forest sector contribution. The results showed the contribution of forestry sector in the period 2000 to 2011 ranged from 2.40% to 5.36%. This forestry sector is a major sector as indicated by Location Quotient value ranging from 1.05 to 1.44. The multiplier effect values varied from 41.23 to 43.05.

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.
