Abstrak: Forest is a natural resource that has a strategic role. Therefore it has to be optimally managed such as by developing a recreation area. WWKM is one of recreation area in Rembang formerly managed by KPM Mantingan and later managed by KBM JLPL. Revenue and cost have to be pointed out in developing WWKM to determine the business feasibility This study analyze visitor characteristic and analyze WWKM business feasibility. Methods used in this study are calculate and analyze using NPV, BCR, and IRR criteria; calculate the payback period and sensitivity analysis. WWKM visitor’s characteristics are female visitors 53%, visitors from Rembang 45%, visitors with high school educated are 50%, self-employed visitors 32%, visitors with income from Rp 500.000 – Rp 1000.000 are 25%, visitors think that the ticket price is average 44%. Visitors satisfy with existing facilities 54% and visitors expected more game facilities are 38,346%. Based on feasibility analysis and taken from the entire investment with NPV Rp 223.397.974, BCR 1.117 and IRR 16.985% indicate that WWKM was an appropriate business before it was runned by KBM JLPL. It also a valuable business under KBM JLPL management with NPV Rp. 774.737.902, BCR of 1.572 and IRR of 47.697%. In fourth year ( 3 years and 8 months ) this project has refund its investment. This project is more sensitive to income decrease than cost increase. If expense raise to 58% will cause a negative NPV (Rp 11.177.040) and the NPV will down to (Rp 13.274.654) if revenue decrease to 37%.

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.
