Judul: Potensi Sumberdaya Mangrove Sebagai Dukungan Ekowisata Pantai Pasir Perawan Pulau Pari
Abstrak: Pulau Pari memiliki potensi sumberdaya laut yang besar dengan keanekaragaman hayati yang tinggi salah satunya ekosistem mangrove. Ekosistem mangrove memberikan manfaat atau jasa bagi ekosistem dan manusia. Pemanfaatannya berupa kegiatan ekowisata sebagai upaya konservasi mangrove. Potensi ekowisata mangrove yang dapat dikembangkan adalah wisata mangrove Pantai Pasir Perawan. Penelitian ini bertujuan untuk merumuskan strategi pengembangan wisata mangrove sebagai kawasan ekowisata dengan analisis kesesuaian wisata, daya dukung kawasan dan SWOT. Penelitian dilaksanakan pada bulan September hingga November 2023. Pengambilan contoh dilakukan di kawasan mangrove Pantai Pasir Perawan. Pengumpulan data dilakukan melalui observasi lapang dan wawancara pengisian kuesioner. Hasil penelitian menunjukkan bahwa kawasan mangrove di Pantai Pasir Perawan masuk dalam kategori sesuai untuk ekowisata. Pengembangan ekowisata meliputi berperahu dan tracking mangrove, dengan daya dukung masing-masing 120 orang per hari dan 46 orang per hari.Strategi pengembangan ekowisata memprioritaskan tiga alternatif strategi yaitu pengembangan potensi kegiatan tracking mangrove dan berperahu, melakukan promosi serta rehabilitasi mangrove., Pari Island has large marine resource potential with high biodiversity, one of which is the mangrove ecosystem. The mangrove ecosystem provides benefits or services for the ecosystem and humans. The use is in the form of ecotourism activities as a mangrove conservation effort. The potential for mangrove ecotourism that can be developed is the mangrove tourism at Pasir Perawan Beach on Pari Island. This research aims to formulate a strategy for developing mangrove tourism as an ecotourism area by analyzing tourism suitability, regional carrying capacity and SWOT. The research was carried out from September to November 2023. Samples were taken in the mangrove area of Pasir Perawan Beach. Data collection was carried out through field observations and interviews to fill out questionnaires. The research results show that the mangrove area at Pasir Perawan Beach is in the category suitable for ecotourism. Ecotourism development includes boating and mangrove tracking, with a carrying capacity of 120 people per day and 46 people per day respectively. The ecotourism development strategy prioritizes three alternative strategies, namely developing potential mangrove tracking and boating activities, promoting and rehabilitating mangrove.

Judul: Kajian Potensi Wisata Rumput Laut Berbasis Budidaya di Pulau Pari
Abstrak: Pulau Pari kerap dikunjungi banyak wisatawan terlebih saat akhir pekan. Hal ini memungkinkan terjadinya jumlah wisatawan yang melebihi daya dukung kawasan sehingga diperlukan diversifikasi kegiatan wisata. Budidaya rumput laut dapat dijadikan wisata untuk meminimalisir jumlah wisatawan yang berlebihan. Penelitian ini bertujuan menganalisis potensi rumput laut yang dibudidaya di Pulau Pari sebagai wisata secara ekologi, sosial, dan ekonomi serta menyusun strategi dan rencana tapak wisata budidaya rumput laut. Dilakukan observasi langsung dan wawancara selama 20 hari pada 11 November - 30 November 2023. Observasi dilakukan untuk memperoleh informasi mengenai kawasan budidaya dan kondisi perairan. Responden wawancara sebanyak 67 orang meliputi masyarakat, wisatawan, petani rumput laut, dan pemilik produksi oleh-oleh. Dilakukan analisis yang meliputi analisis persepsi, indeks kesesuaian wisata, daya dukung kawasan, willingness to pay, dan SWOT. Kawasan budidaya rumput laut Pulau Pari sesuai untuk wisata dengan daya dukung kegiatan berperahu 160 orang/hari dan snorkeling 123 orang/hari. Penerimaan yang diestimasi sebesar Rp5.984.400 per hari. Alternatif strategi yang direkomendasikan untuk pengembangan kawasan budidaya rumput laut di Pulau Pari sebagai wisata meliputi promosi, perencanaan pengembangan, peningkatan komitmen berbagai pihak dalam menjaga lingkungan perairan, pengadaan kelompok pengelolaan, dan kerjasama dengan pemerintah. Rencana aksi yang perlu dilakukan adalah penyusunan rencana tapak dengan mempertimbangkan strategi yang direkomendasikan., Pari Island is often visited by many tourists, especially on weekends. This allows the number of tourists to exceed the carrying capacity of the area so that diversification of tourism activities is needed. Seaweed cultivation can be used as tourism to minimize the excessive number of tourists. This research aims to analyze the potential of seaweed cultivated on Pari Island as ecological, social, and economic tourism as well as formulate strategies and site plan for seaweed cultivation tourism. Direct observations and interviews were carried out for 20 days on November 11th – November 30th 2023. Observation were carried to obtain information about cultivation area and water condition. The 67 respondents included the residents, tourists, seaweed farmers, and souvenirs production owners. The analysis is perception analysis, tourism suitability index, carrying capacity area, willingness to pay, and SWOT. The Pari Island’s seaweed cultivation area is suitable for tourism with a capacity for boating activities of 160 people/day and snorkeling activity of 123 people/day. The estimated revenue is Rp5.984.400 a day. Alternative strategies recommended for developing the Pari Island’s seaweed cultivation area as tourism include promotion, development planning, increasing the commitment of various parties in protecting the aquatic environment, establishing a management group, and collaborating with the government.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
