Judul: Dampak Kenaikan Muka Laut Terhadap Pengelolaan Pesisir Cagar Alam Pulau Dua dan Keterkaitan dengan Kawasan Penyangga di Kecamatan Kasemen Kota Serang Provinsi Banten
Abstrak: Pulau Dua Nature Reserve (CAPD) is located in Banten Bay on 06o01’05”– 06o02’05”South and 106o11’38”– 106o13’14”East under administrative area of Sawah Luhur village of Serang municipality. The function of CPAD is very important for about 108 species of birds where 38 species of its categorized as protected by national and or international convention. An area of 28,6 hectares mangrove as the main vegetation of 30 hectares CAPD leads important role as well as natural protection for 515 hectares of fish ponds, 2910 families and also support rice production of Serang and its surrounding. Topography of CAPD and its surrounding ecosystem are a gently sloping low land area with the highest contour is 4m above MSL. Due to this topography condition and located directly faced Java Sea, caused this area is very vulnerable to the impacts of sea level rise. Simulation models of sea level rise for scenario 25cm, 50cm and 100cm combining with contour map are able to predict the changes of ecological landscape of land inundation and economic losses incurred. Calculation of economic losses in this study carried out by using economic valuation method of mangrove ecosystem, as mangrove e is the main vegetation of CAPD. Sea level rise on scenario 25cm shown taht 427, 22 ha of fish ponds will permanently inundate and no more operates or about 5.699.542.020 IDR will be losses. On scenario of 50cm shown 535,60 ha fish ponds and 10ha CAPD will be loss with economic value losses is IDR 11.261.056.639. On scenario 100cm, about 569,54 ha area will be loss namely all of area of fish pond, 28ha of CAPD, village road and settlement. Area management strategy to answer this problem was developed through SWOT analysis on vulnerability level of natural, human resource and socio economic conditions. Through this analysis can be recommend an ecological planning method as the strategy of coastal management of Sawah Luhur village.

Judul: Status Ekologi Mangrove untuk Upaya Pengelolaannya di Kawasan Pesisir Pulau Dua, Kecamatan Kasemen, Serang, Banten (di Luar Cagar Alam Pulau Dua)
Abstrak: Lokasi penelitian merupakan salah satu kawasan pesisir di Kecamatan Kasemen yang berada di dua desa, yaitu Desa Banten dan Sawahluhur, dengan ketinggian 0-10 meter di atas permukaan laut (dpl) dan suhu udara rata-rata 32 oC. Di sepanjang garis pantai terdapat ekosistem mangrove yang secara visual ketebalannya tidak sama bahkan beberapa tempat tidak ditemukan sejumlah vegetasi mangrove. Di belakang mangrove terdapat lahan pertambakan yang tersebar secara luas. Sistem estuaria terdekat adalah Sungai Cengkok dan Sungai Pelabuhan yang bermuara ke Teluk Banten. Adapun tujuan penelitian ini adalah mengetahui kondisi ekosistem mangrove dengan komponen pendukungnya seperti kondisi perairan maupun organisme yang berasosiasi seperti gastropoda dan sumberdaya udang. Penelitian dilakukan pada bulan Juni-Agustus 2009 di kawasan pesisir Pulau Dua (di luar Cagar Alam Pulau Dua), Kecamatan Kasemen, Serang, Banten. Pengambilan sampel mangrove dan gastropoda dilakukan pada 6 (enam) stasiun dengan masingmasing stasiun tiga replikasi. Pengambilan mangrove dilakukan secara kombinasi antara metode transek garis (sejajar garis pantai) dengan transek kuadrat. Untuk pengambilan sampel air dilakukan di bagian pantai, tepat di depan vegetasi mangrove di setiap stasiun. Data sumberdaya udang yang diolah merupakan sumber data sekunder yang diperoleh dari nelayan pengumpul, khususnya dari hasil tangkapan dengan menggunakan alat tangkap sero.

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
