Judul: Stakeholder Analysis in Sugar Palm Conservation in The Buffer Village of Mount Rinjani National Park, West Nusa Tenggara Province
Abstrak: Aren (Arenga pinnata (Wurmb) Merr.) merupakan salah satu komoditas yang memiliki nilai ekonomi dan ekologi tinggi di desa penyangga Taman Nasional Gunung Rinjani. Pengelolaan potensi dalam konservasi aren dari hulu ke hilir di Desa Aik Bual memerlukan peran aktif dari para pemangku kepentingan (stakeholder). Tujuan dari penelitian ini adalah mengidentifikasi stakeholder berdasarkan pengaruh dan kepentingannya, memetakan stakeholder sesuai dengan kapasitasnya, serta merumuskan hubungan antar stakeholder dalam pengembangan kolaborasi. Penelitian ini dilakukan di Desa Aik Bual pada bulan Agustus-Oktober 2022. Pengambilan data dilakukan dengan metode wawancara, pengamatan lapang, studi pustaka, dan focus group discussion. Analisis data yang digunakan meliputi analisis stakeholder, identifikasi stakeholder, klasifikasi stakeholder, dan hubungan antar stakeholder. Hasil dari penelitian ini menunjukaan bahwa terdapat 13 stakeholder yang mencakup unsur pemerintah, industri, masyarakat, dan akademisi. LSM Gaya merupakan stakeholder yang memiliki nilai paling tinggi karena berperan dominan dalam melaksanakan kegiatan konservasi aren dari proses hulu ke hilir. Desa Aik Bual berperan sebagai aktor yang paling sentral di dikarenakan memiliki peran dalam menghubungkan kepentingan antar stakeholder dalam bentuk penguasaan wilayah secara administrasi serta Tupoksi. Kata kunci : aren, desa penyangga, hubungan antar stakeholder, Sugar palm (Arenga pinnata (Wurmb) Merr.) is a commodity that has high economic and ecological value in the buffer zone of Mount Rinjani National Park. The management of potential in the conservation of sugar palm in Aik Bual Village requires the active role of stakeholders. The purpose of this study is to identify stakeholder based in their influence and interests, map stakeholders according to their capacities, and formulate relationships between stakeholders in collaborative development. This research was conducted in Aik Bual Village in August-October 2022. Data retrievalwas done by interviews, field observations, literature studies, and focus group discussion. The data analysis used includes stakeholder analysis, identification of stakeholders, classification of stakeholders, and relationship between stakeholder. The result of this study indicate there are 13 stakeholders including elements of government, industry, society, and academia. Gaya NGO is a stakeholder who has the highest value among other stakeholders because it plays a dominant role in carrying out sugar pal conservation activities from upstream to downstream processes. Aik Bual Village acts as the most central actor because it has a role in connecting between stakeholders’ interest in the form of administrative control of the area and main tasks and function.

Judul: Standing and Habitat Condition of Sugar Palm (Arenga pinnata. (Wurmb.) Merr.) ‎in Hariang Village, Sobang District, Lebak Regency, Banten Province.
Abstrak: Pemanfaatan nira aren di desa hariang sudah dilakukan untuk waktu yang ‎cukup lama, oleh karena itu dilakukan penelitian untuk mengetahui seberapa besar ‎potensi nira aren yang dapat di manfaatkan. Penelitian ini bertujuan untuk ‎menduga potensi tegakan aren yang dapat di produksi niranya, mengidentifikasi ‎tingkat regenerasi serta pola persebaran, mengetahui tipologi habitat aren, serta ‎mengidentifikasi spesies vegetasi yang tumbuh di sekitar habitat aren. Penelitian ‎dilakukan pada kedua lereng yang menghadap kearah mata angin barat dan timur ‎dengan menggunakan metode observasi lapang, wawancara kepada beberapa ‎narasumber, analisis vegetasi dengan ukuran plot 20m x 20m, serta mencari ‎beberapa literatur yang sebagai acuan dan pendukung untuk hasil yang di dapat ‎dalam penelitian. Pada hasil penelitian di temukan persentase potensi tumbuhan ‎aren yang dapat di produksi sebesar 3% pada desa Hariang. Tingkat regenerasi ‎aren yang di dapat berada pada kategori bagus dengan pola persebaran yang ‎seragam. Sebanyak 48 jenis tumbuhan di temukan pada habitat aren. Vegetasi ‎hutan di sekitar desa hariang tergolong kedalam hutan rakyat dengan pola kebun ‎campuran. Hasil dari penelitian ini dapat dijadikan sebagai data tambahan dalam ‎upaya pengelolaan habitat aren.‎, Utilization of palm sap in Hariang village has been carried out for quite a ‎long time, therefore a study was conducted to find out how much potential palm ‎sap can be utilized. This study aims to estimate the potential of sugar palm stands ‎that can be produced for sap, identify the level of regeneration and distribution ‎patterns, determine the typology of sugar palm habitat, and identify vegetation ‎species that grow around the sugar palm habitat. The study was conducted on ‎both cliffs, each facing the west and east cardinal directions using field ‎observation methods, interviews with several sources, analysis of vegetation with ‎a plot size of 20m x 20m, and looking for some literature that can be used as a ‎reference and support for the results obtained. obtained in research. In the results ‎of the study, it was found that the percentage of potential sugar palm plants that ‎could be produced was 3% on Hariang village. The level of regeneration of sugar ‎palm that can be obtained is in the good category with a regular distribution ‎pattern. A total of 48 species of plants were found in the sugar palm habitat. The ‎forest vegetation around Hariang village is classified as community forest with ‎mixed garden pattern. The results of this study can be used as additional data ‎needed in efforts to manage sugar palm habitat.‎

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.
