Judul: Ecotourism Development with an Approach  Resource Valuation of the Perawan Beach of Pari Island, Seribu Islands
Abstrak: Pantai Perawan merupakan salah satu objek wisata yang berada di Pulau Pari. Pengembangannya harus memperhatikan komponen yang mengutamakan unsur sumberdaya alam dengan mempertimbangkan aspek sosial, ekonomi dan budaya. Penelitian ini bertujuan untuk Penelitian ini bertujuan untuk menganalisis potensi sumberdaya dan daya dukung Pantai Perawan Pulau Pari untuk pengembangan ekowisata dengan pendekatan valuasi sumberdaya. Memberikan kuesioner merupakan cara mendapatkan data untuk mengetahui informasi nilai travel cost method dan willingness to pay. Pendekatan SWOT digunakan untuk menganalisis strategi pengelolaan. Faktor yang mempengaruhi kegiatan wisata yakni umur dan biaya perjalanan. Rataan willingness to pay sebesar Rp 15.500. Strategi yang digunakan untuk pembangunan wisata yakni dengan meningkatkan fasilitas-fasilitas wisata dan juga membuat forum musyawarah untuk pembuatan lembaga untuk meningkatkan pengembangan ekowisata.

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. Thus, tourist activity in Pari Island can be developed with limit of environmental carrying capacity.

Judul: Molecular Identification of Mutant Candidate of Gα Gene from Soybean cv. Slamet Based on mRNA.
Abstrak: Heterotrimeric G proteins composed of α, β, and γ subunits, are bound to the inside surface of the cell membrane. Gα proteins will be activated by extracellular stimuli (biotic or abiotic stress). It is presumably Gα proteins playing an important role in aluminum (Al)-stress tolerance. Soybean cv. Slamet was considered as a tolerant plant to Al and has a single copy of Gα gene. Gamma irradiation to soybean cv. Slamet seeds caused a random chromosomal mutation of second generation plants (designated as M2). The Gα mutant candidates were selected based on stomatal closure in the daylight and dwarf. Gα mutant candidates M4, number 338 and 103 have severe root cell tissues damage compared to non mutant ones. Plant number 338/3S1.174/12/14 (M4) and 103/3S3.103/8/5/1/4 (M5) have a Gα gene mutation at the U3-L4 sequences (exon 5 – exon 11). Whereas, plant number 344/3S1.196/14/1/8 (M4) is assumed as Gα gene mutant. All of those plants were replanted until sixth generation. The candidates of Gα mutant selected have more than fifty percent of closed stomata and dwarf. Four number of M5 plants and three number of M6 plants were selected for Gα mutant identification based on mRNA analysis. The fifth generation plant number 344/3S1.196/14/1/8/7 were decreased its Gα gene expression at L5-L4 sequences (exon 7 – exon 11). The M6 generation plant number 344/3S1.196/14/1/8/7/5 have mutation in Gα gene at L1-L3 sequences (exon 2 – exon 6). A major contributing factor to decreased expression levels of Gα gene may be due to mutation of Gα gene promotor. Three other of M5 plants were assumed as Gα mutant. M6 plant number 103/3S3.103/8/5/1/4/8 has mutation at L3-L2 sequences (exon 6 – exon 15) and number 103/3S3.103/8/5/1/4/9 has mutation at U3-L4 sequences (exon 5 – exon 11). The decreasing of gene expression caused by mutation in those plants was indicated by the less pronounced DNA bands on agarose gel than that of non mutant plants.
