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: Mangrove Resources Management Strategy in Pari  Island, Seribu Islands
Abstrak: SHAVA HUSNANIZAHWA. Strategi Pengelolaan Sumberdaya Mangrove di Pulau Pari, Kepulauan Seribu. Dibimbing oleh Prof. Dr. Ir. FREDINAN YULIANDA, M.Sc. dan Prof. Dr. Ir. MENNOFATRIA BOER, DEA. Ekosistem mangrove memiliki peran penting dalam komponen penyusun wilayah pesisir yaitu menjaga garis pantai dan mencegah terjadinya abrasi. Ekosistem mangrove berfungsi sebagai tempat pemijahan (spawning ground), tempat pengasuhan (nursery ground), dan tempat mencari makan (feeding ground) oleh biota laut. Masyarakat sering mengambil buah mangrove dan nelayan biasanya menangkap ikan di sekitaran mangrove. Destinasi wisata yang ditawarkan oleh masyarakat yaitu mengelilingi hutan mangrove menggunakan perahu milik masyarakat. Pengelolaan yang dilakukan oleh masyarakat Pulau Pari masih mengedepankan mass tourism sehingga dihawatirkan menimbulkan kerusakan dan pencemaran lingkungan. Tujuan penelitian adalah mengetahui kondisi sumberdaya mangrove dan menentukan strategi pengelolaan pada sumberdaya mangrove. Penelitian dilaksanakan pada bulan September hingga November 2023 di Pulau Pari, Kepulauan Seribu. Analisis yang digunakan adalah Indeks kesehatan mangrove (IKM) dan analisis SWOT. Hasil yang diperoleh adalah nilai IKM pada area penelitian tergolong kedalam kategori sedang. Terdapat tiga jenis mangrove yaitu Rhizophora stylosa, Rhizophora apiculata dan Sonneratia alba. Strategi alternatif berdasarkan prioritas untuk pengelolaan sumberdaya mangrove yaitu implementasi dan penegakan aturan yang jelas terkait pengelolaan mangrove dengan adanya keterlibatan antara pemerintah dan masyarakat serta melakukan konservasi mangrove berbasis masyarakat dengan adanya keterlibatan pemerintah., SHAVA HUSNANIZAHWA. Mangrove Resources Management Strategy in Pari Island, Seribu Islands. Supervised by Prof. Dr. Ir. FREDINAN YULIANDA, M.Sc. and Prof. Dr. Ir. MENNOFATRIA BOER, DEA. The mangrove ecosystem plays an important role in the components of coastal areas by maintaining the coastline and preventing erosion. The mangrove ecosystem functions as a spawning ground, nursery ground, and feeding ground for marine biota. The community often harvests mangrove fruits, and fishermen usually catch fish around the mangroves. The tourism destination offered by the community includes tours around the mangrove forest using local boats. The management conducted by the Pulau Pari community still prioritizes mass tourism, which is feared to cause damage and environmental pollution. The aim of the study is to determine the condition of mangrove resources and to develop a management strategy for these resources. The research was conducted from September to November 2023 on Pari Island, Seribu Islands. The analyses used are the Mangrove Health Index (IKM) and SWOT analysis. The results show that the IKM value in the research area falls into the poor category. There are three types of mangroves Rhizophora stylosa, Rhizophora apiculata, and Sonneratia alba. The alternative strategy based on priority for mangrove resource management includes the implementation and enforcement of clear regulations regarding mangrove management with the involvement of both the government and the community, and conducting community-based mangrove conservation with government participation.

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.
