Judul: Optimasi Penentuan Lokasi dan Analisis Tata Letak Industri Buah Kering (Dried Fruit) di PT Great Giant Pineapple Lampung Tengah.
Abstrak: The opportunity of dried fruit market in Europe in average is about 45% from global import volume. These opportunities were caused by inexpediency of Europe’s climate for tropical crops and as tropical country, Indonesia had opportunity to export commodities like mango, papaya, pineapple, guava, and ginger. The result objective were determining of optimum location, location factors, production capacity, and dried fruit industry’s layout analysis. Methods of this research are location candidates determining, questionnaire distributing, production capacity determining, transportation load total calculating (load distance model method), location alternatives evaluation (composite performance index and bayes method), and department layout analysis in dried fruit industry. Industry’s capacity are about 1,596 ton/year (product) or 9,493 ton/year (raw material). Factors to choose location include raw material cost, clean water access availability, waste water acces availability, and salary cost. Choosen location was Kediri Regency. Need area width were 4,790.60 m2.

Judul: Sistem penunjang keputusan perencanaan pengembangan agroindustri Manggis (Garcinia mangostana Linn) (studi kasus di Kabupaten Bogor)
Abstrak: Mangosteen has become the Queen of commodities to export fresh fruit to foreign countries. But the numbers are still about 20% of the total production in Indonesia is mostly caused by low quality of the fruit. For that, they need diversified commodities processed mangosteen products. The objectives of this research to develop a model of decision support system for mangosteen agroindustry development in bogor district and recommend a strategy for planning and development of the agroindustry to the government of Bogor district and mangosteen prospective employers. Decision support system for mangosteen agroindustry development implemented into a computer program package called mangosteen 1.0 by using Pascal programming language in Embarcadero Delphi XE which consists of six models, including model of prospective product, site analysis model, model of analysis production centers, model of the mangosteen cultivation financial feasibility, model of agro-industry financial feasibility, and model of mangosteen development strategy. Decision support system using the comparison ekponensial method ( MPE), and analitical Hierarchy Process method (AHP). This mangosteen agro-industrial is plan to be located in Dramaga based on site selection using MPE method with a capacity of 50.000 bottles of mangosteen xanthone per month. This research programme shows that the mangosteen agro-industrial of xanthone is feasible with NPV Rp. 8.804.311.994, IRR 52%, Pay Back Period (PBP) 3 years and 3 months, and B/C Ratio 2.76.

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.
