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.

Abstrak: Integrated coastal management model is essential in the management and utilization of resources of small islands. Some marine tourism sites that attract are able to collapse by the activity of marine tourism too. The research has been done in Hoga Island, Wakatobi Regency, since February to December 2012. This study was aimed to analyze the sustainability of marine ecotourism that utilized of coral reef resources by means of the integrated stakeholders approach. In this study, the means of stakeholder were the government, private sector and local community. The three categories of marine ecotourism activity that observed were diving, snorkeling and beach recreation. Based on the suitability analysis from Yulianda (2007), so the location that suitable to dive with totally utilization of carrying capacity were 77 people/day. The appropriated location for snorkeling was the coral reef shelf in the west of Hoga Island with carrying capacity of utilization amounts 2213 people/day. The location that suitable with the beach recreation was in the beachs with amounts utilization carrying capacity 68 people/day. The profit of marine ecotourism activities that acceptable to stakeholder i.e for local community obtained Rp. 1.125,9 million in 2011 from 5 types of business sector and 20 types of vocation. In the 2011, the acceptable of income to the government by tax and entrance fee to marine ecotourism in Hoga Island were Rp. 81,7 million. In the 2010, the organizer of marine ecotourism in Hoga Island had amounts 14,5% of total income from the marine ecotourism activities. Whereas the multiplier effect of marine ecotourism for Keynesian Local Income Multiplier obtained 0,38; for Ratio Income Multiplier Type I obtained 1,57; and for Ratio Income Multiplier Type II obtained 2,27. In the 2011, the total economic value of coral reefs in Hoga Island in 2011 is Rp. 11,88 billion. The resulted of Cluster Analysis to stakeholder were obtained the primary of stakeholder, i.e. Tourism Department of Wakatobi Regency, Wakatobi National Park (BTNW), Wallacea Operation (Opwal), Wakatobi Nature Foundation, The Group Business Community, and The Group Workers Community. The resulted of sustainability analysis shown that status of marine ecotourism sustainability in Hoga Island were potential sustainability categories (60,54).

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.
