Abstrak: This research is aimed to formulate a zonation of conservation area and development plan of marine ecotourism in Dodinga Bay, West Halmahera Regency, North Maluku Province. The primary data consist of biophysical condition, social economic, accessibility, and level of tourist visits, which were collected by survey method, observation and interview with local community, tourist and other stakeholders at 7 observation station. Analysis data consisted of two approaches; geographyc information system (GIS) for formulating zonation area and analitycal hierarchy process (AHP) for formulating development plan of marine ecotourism. Based on zonation analysis, this area was devided using ecologycal, social and economical criteria approach into 3 management zones: sanctuary zone (station 5) with the total areas 141.86 ha, utilization zone spreaded on station 1, 2, 4, 6 and 7 with the total areas 1 383.51 ha and suistainable utilization zone (station 3) with the total areas 138.01 ha. The total area for diving tourism is 96.44 ha with 75.91% of coral cover 71.73% and its carrying capacity is 189 people/area/day. The total area of snorkeling tourism is 53.93 ha with 70.98% of coral cover and its carrying capacity is 535 people/area/day. The economic value of tourism is $US. 5 957 562.67/year. Based on AHP analysis, alternative of tourism development provided the highest scoring of 70.25% on the full community involvement. Its involvement was collaboration between private sector and community which is facilitated by local government with the scoring value 14.77% and 14.99% respectively. Based on zonation analysis using ecological criteria, economical and social criteria, Dodinga Bay area was devided on three zones ; sanctuary zone located at 0⁰ 52' 11.82" N - 127⁰ 33' 15.66" E, utilization zone located at 0⁰ 52' 44.00" N – 127o 35' 5.57" E and suistainable utilization zone located at 0⁰ 51' 11.27" N – 127o 37' 28.81" E. Management policy and development of Dodinga Bay as a marine ecotourism must be supported by its community or community based management.

Judul: Development model for regional conservation of coastal and small islands: case study of Weda Bay.
Abstrak: A study on development model for regional conservation in the coastal and small islands of Weda Bay, Regency Central Halmahera, Province North Maluku was conducted from June to November 2012. The objectives of the study were 1) to assess and identify existing ecosystem and natural resources there in; 2) to analyze the suitability of conservation area for marine fisheries ecotourism; 3) to analyze assimilative capacity and carrying capacity for environmental utilization; and 4) to analyze structural institution model based on tourism demand, marine fisheries ecotourism, and the sustainability of coastal and small islands in Weda Bay. Analyses performed for this study were 1) toponymy analysis, based on species identification, diversity, and lifeform; 2) conservation criteria, suitability matrices, and spatial analysis; 3) assimilative thresholds and carrying capacity for environment and utilization; 4) Travel Cost Method (TCM), Interpretative Structural Modeling (ISM) and Rapfish. From this study, there are 28 uninhabited islands, 6 families of mangroves, 10 species of seagrass, 14 types of lifeform with dominant reef feature of fringing and barrier, while bottom feature consisted of slopes and drop offs. To accommodate both conservation and economic development, mangrove area should be developed for ecotourism purpose. Assimilative capacity in this study indicated that several chemical parameters were under threshold limits for mariculture, port, and tourism development. Carrying capacity for marine fisheries ecotourism indicated that dominant use should directed to mangrove tourism. Finally, development model for supporting increased tourist visits to study area should consider travel cost and tourist income according to country of origin. Institutional management for coastal and small islands should incorporate government, tourists and university, in order to promote sustainable development for tourism and natural resource production. For supporting local fish-based product, fisherman, and capture fishery capitalization, there should be regulation in setting market price, fishery resource management, regional investment regulation, and consistent applied policy. Optimal sustainability for development of coastal and small islands in Weda Bay is possible when improvements are applied to ecology, economy, socio-culture, and institutional dimension.

Judul: Sintesis Krisin dari Floroglusinol
Abstrak: Flavone is a class of flavonoid, widely distributed in vascular plants. Flavones containing hydroxyl groups at 5 and 7 position are quite important regarding their biological activities and their abiquity in nature. Flavone having hydroxyl groups only at position 5 and 7 or 5,7-dihydroxyflavone is known as chrysin. In this study, crude chrysin had been successfully synthesized in 3 steps from phloroglucinol as starting material. Phloroglucinol was acetylated with acetonitrile and HCl gas, resulting phloroacetophenone amount to 74%. Phloroacetophenone benzoylation with 4.5 equivalents of benzoyl chloride produced tribenzoyl phloroacetophenone in 103–107% of yield and the subsequent Baker-Venkataraman rearrangement of the ester by using KOH in dried pyridine produced crude chrysin, with conversion percentage of 71.62%. All synthetic products had been characterized by melting point and spectroscopically.
