Judul: Kajian Kondisi Terumbu Karang dan Komunitas Ikan Karang di Kawasan Konservasi Pulau Biawak dan sekitarnya, Kabupaten Indramayu Propinsi Jawa Barat
Abstrak: Marine Conservation area which is well protected will be ecologically gives positive impact on the abundance and biomass of target species and non-target fish in the area and the surrounding areas (Polunin et al. 1993). The declaration of Biawak Island and Surrounding Areas as a marine conservation area based on the Head of Indramayu District Government Decree number 556/Kep.528- Diskanla/2004 issued on April 7, 2004 on the establishment of Biawak Island and Surrounding Areas as a Marine Conservation Areas and Tourism, one of whose objectives is the protection of habitat and population, is expected to maintain the condition of ecosystems and provide a positive impact on marine resources both ecological, economic, and social. The purpose of this study was to examine the effect of the establishment those areas on coral reef and reef fish communities by studying condition percent cover of coral reef, reef fishes species diversity, abundance and fish biomass. Results showed that there are decrease number of coral reefs percent covers and the low biomass of fish in that the region.

Judul: Pengelolaan Ekosistem Terumbu Karang Untuk Kegiatan Ekowisata Selam Di Pulau Biawak, Indramayu, Jawa Barat
Abstrak: Potensi ekosistem terumbu karang di Pulau Biawak dapat dimanfaatkan untuk kegiatan wisata bahari, salah satunya adalah wisata selam. Upaya pengendalian dampak kegiatan wisata dapat menggunakan pendekatan ekowisata. Kajian ini dilakukan untuk menganalisis kesesuaian wisata dan daya dukung kawasan serta merumuskan arahan strategi pengelolaan dan pengembangan ekowisata selam. Identifikasi karang dikaji menggunakan metode LIT (Line Intercept Transect) sedangkan kelimpahan jenis ikan karang dikaji menggunakan metode fish visual cencus. Analisis data yang digunakan adalah analisis potensi terumbu karang, analisis kesesuaian lahan, analisis daya dukung dan analisis SWOT. Tutupan komunitas karang hidup berkisar antara 49,82%-66,4% dengan keragaman jenis ikan karang berkisar antara 16–29 jenis. Indeks kesesuaian wisata (IKW) selam di Pulau Biawak termasuk dalam kategori sesuai (S2) dan sangat sesuai (S1) dengan nilai daya dukung kawasan adalah 84 orang/hari. Strategi prioritas yang perlu dilakukan di kawasan Pulau Biawak adalah strategi pengelolaan WT (Weaknees Threat) , yaitu dengan penentuan zonasi kawasan konservasi di Pulau Biawak.

Judul: Sintesis α-Fe2O3 menggunakan metode sol gel
Abstrak: In this reseach was succeeded make powder α-Fe2O3 with particle size 202.64 nm. Synthesis using Sol-Gel method with SiO2 coating derived from Si(OC2H5)4 at temperature of 750 oC for 5 hours. Characterization XRD prove that sample form is α-Fe2O3 (11 peaks) and β-Fe2O3 (2 peaks) with crystal size 20.69125 nm and crystallization 44 %. The cystal structure of α-Fe2O3 is rhombohedral and β-Fe2O3 is hexsagonal. Optic characterization show that the sample absorbing light at wavelength less than 480 nm. Bandgap energy of the optical characterization measurments is 2.74 eV.
