Judul: Penilaian Ekonomi dan Daya Dukung Wisata Bahari di Pulau Pari Kepulauan Seribu Provinsi DKI Jakarta
Abstrak: The economic assessment and carrying capacity of Pari island marine tourism in Thousand islands of DKI Jakarta province are intended to determine the land suitability of Pari island for the marine tourism, to estimate the physical carrying capacity of Pari island for the marine tourism, to estimate the economic values of Pari island for the marine tourism and the economic impacts for the local people. The analysis of tourism land suitability shows that the group of Pari island in accordance with the parameter of brightness and flow velocity is really appropriate with the parameter of the types of coral reefs and reef fish species, is appropriate with margin and is sufficiently appropriate with the live coral cover; and in accordance with the width parameter is of the potential for 361,5 ha diving and 939,55 ha snorkeling activities. The carrying capacity of the group of Pari island for diving tourism is 1.287 people/day, for snorkeling tourism is 2.787 people/day, for mangrove tourism is 504 people/day, and for beach tourim is 2.572 people/day. The results showed the total economic value of marine tourism in Pari island about 12.365.824.221,25 IDR or 192.314.529,10 IDR per hectare/year. Keynesian Local Income Multiplier value of cash flow marine tourism activities in Pari Island showed a value of 1,48, Income Multiplier Ratio Type I and Income Multiplier Ratio Type II with value of 1,09, and 1,14.The recommendations for the marine tourism development in Pari island are among other: the settlement of land ownership status; involvement, capacity development, and community empowerment; the opening of direct transport access toward Pari island; the improvement of infrastructures and tourism supporting facilities

Judul: Analisis Ekonomi dan Daya Dukung Pengembangan Ekowisata Pulau Pari Kepulauan Seribu, Jakarta
Abstrak: Pari Island wich is known as research and conservation area of coral reefs by P2O LIPI, now also developed as a natural tourism area. One of the purposes of tourism development in Pari Island is to increase local economy. Most of the local people in Pari Island work in fisheries sector which now face a fish stock depletion due to the overfishing problem. Thus the tourism sector is expected to contribute to the local community income. This study was conducted to calculate the carrying capacity of Pari Island for beach and snorkeling activities, estimating the economic value of tourism in Pari Island, and the contribution of the tourism sector to local community income. Based on calculation, the value of tourism suitability index and carrying capacity of the location are in the category suitable. The economic value of tourism in Pari Island are estimated using individual travel cost method and show the results Rp 152.627.300.000,00/year. The existence of the tourism sector in Pari Island also contributed 70,12 percent to local community income. The number of economic value and tourism contribution to the local community income are indirectly indicate that tourism sector in Pari Island is important for society and the environment.

Judul: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol
