Judul: Conservation-Based Star Beach Tourism Development Strategy on Pari Island
Abstrak: Pantai Bintang merupakan pantai yang dikelola oleh kelompok masyarakat di Pulau Pari. Pantai Bintang memiliki potensi berupa hamparan pasir yang putih dan tidak terdapat biota berbahaya. Pantai Bintang mengalami kerusakan akibat dari bencana banjir rob sehingga terjadi pengikisan pantai. Masyarakat setempat mulai mengembangkan dan memperbaiki kerusakan Pantai Bintang dikarenakan jumlah wisatawan terus meningkat. Penelitian ini bertujuan untuk merumuskan strategi pengembangan pantai berbasis konservasi dengan menggunakan analisis kesesuaian wisata, daya dukung kawasan, dan analisis SWOT. Penelitian dilaksanakan pada bulan September sampai November 2023 di Pantai Bintang, Pulau Pari, Kepulauan Seribu. Pengumpulan data dilakukan dengan observasi lapang dan wawancara. Hasil penelitian yang didapatkan bahwa wilayah Pantai Bintang yang sesuai lebih banyak bila dibandingkan dengan yang tidak sesuai. Daya dukung kawasan untuk rekreasi pantai sebanyak 46 orang/hari. Strategi yang dapat dikembangkan adalah meningkatkan promosi mengenai potensi dan keunggulan pantai, menutup kawasan wisata yang tidak sesuai sementara untuk dilakukan rehabilitasi, dan menanam mangrove guna mencegah abrasi., Pantai Bintang is a beach managed by a community group on Pulau Pari. Pantai Bintang features potential in the form of white sandy expanses and is free from harmful biota. The beach has suffered damage due to tidal flooding, leading to coastal erosion. Local communities have begun efforts to develop and repair Pantai Bintang due to increasing tourist numbers. This study aims to formulate a conservation-based beach development strategy using tourism suitability analysis, area carrying capacity, and SWOT analysis. The research was conducted from September to November 2023 at Pantai Bintang, Pulau Pari, Kepulauan Seribu. Data collection involved field observations and interviews. The research findings indicate that a significant portion of Pantai Bintang is suitable compared to unsuitable areas. The area's carrying capacity for beach recreation is 46 people per day. Proposed strategies include enhancing promotion of the beach's potential and strengths, temporarily closing unsuitable tourist areas for rehabilitation, and planting mangroves to prevent erosion.

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: The Exploration of Discrete Logarithm over Finite Field GF(3m)
Abstrak: The security of many public~key algorithms is based on the problem of finding discrete logarithms. The generalized discrete logarithm problem is the following: given a finite cyclic group G of order n, a generator a of G, and an element fl E G, find the integer x, 0 ~ x ~ n - 1, such that 0: = fl. Algorithm for discrete logarithm problem focused on Menezes et al. (1997) that consist of exhaustive search algorithm, the baby-step giant-step algorithm, Pollard's rho algorithm, Pohlig-Hellman algorithm, and index-calculus algorithm. These algorithms are explorated to be used in discrete logarithm problem over finite field GF(3m ). The exploration also produces some algorithms, i.e. naif negative algorithm, baby-step mother-step algorithm, baby-step mother free-step algorithm, and baby-step free-step algorithm. All algorithms implemented using Maple 11. The Pohlig-Hellman and baby-step giant-step algorithms are efficient enough to be used in discrete logarithm problem over finite field GF(3m ) for m < 20.
