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: Potential Analysis of Beach Ecotourism for Ecotourism development at Perawan Beach, Pari Island, Thousand Islands
Abstrak: Pantai Perawan merupakan objek wisata yang memiliki potensi sumberdaya pantai untuk dikembangkan ke arah ekowisata. Penelitian bertujuan menentukan strategi pengelolaan berdasarkan potensi dan kesesuaian sumberdaya, daya dukung dan persepsi pengunjung ekowisata pantai pada masa pandemi Covid-19 di Pulau Pari, Kepulauan Seribu, DKI Jakarta. Penelitian dilaksanakan pada Juni 2021 hingga Maret 2022. Analisis yang digunakan yaitu indeks kesesuaian wisata, daya dukung kawasan, analisis persepsi dan analisis SWOT. Hasil penelitian menunjukkan kesesuaian wisata Pantai Perawan masuk ke dalam kategori sesuai dan sangat sesuai dengan daya dukung 20 orang/hari. Berdasarkan persepsi wisatawan, kenaikan tarif masuk pantai dapat dilakukan untuk kebutuhan peningkatan kawasan pantai. Peningkatan yang dapat dilakukan di kawasan Pantai Perawan yaitu peningkatan sarana dan prasarana, peningkatan keselamatan dan keamanan pantai serta pemeliharaan sumberdaya pantai. Strategi pengelolaan pantai yang dapat digunakan untuk pengembangan ekowisata yaitu menjadikan Pantai Perawan menjadi wisata ekslusif dengan jumlah pengunjung yang terbatas, melakukan kerjasama dengan pemerintah maupun swasta di bidang pariwisata dan konservasi, melakukan kerjasama dengan stakeholder baik pemerintah maupun masyarakat dalam pengembangan ekowisata, Perawan Beach is a tourist attraction with potential coastal to be developed for ecotourism. The research aims to determine management strategies based on the potential and suitability of resources, carrying capacity, and visitor perceptions of beach ecotourism during the COVID-19 pandemic on Pari Island, Thousand Islands, DKI Jakarta. The research was conducted between June 2021 to March 2022. The analysis used in the research is the tourism suitability index, carrying capacity, perception analysis, and SWOT analysis. The analysis's results indicate that the suitability index of Perawan Beach is in the suitable and very suitable categories, with a carrying capacity of 20 guests per day. Based on tourist perceptions, an increase in the entrance fee for the beach can be made to accommodate the need to increase the beach area. Improvements that can be made in the Virgin Beach area include improving facilities and infrastructure, increasing beach safety and security, and maintaining coastal resources. Management Strategy is obtained from SWOT analysis. Beach management strategies that can be used for ecotourism development include making Perawan Beach exclusive to tourism with a limited number of visitors, collaborating with the government and the private sector in tourism and conservation, and collaborating with stakeholders both in government and the community in developing ecotourism

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.
