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: Potential and Utilization of Aren (Arenga pinnata (Wurmb) Merr.) in the Buffer Village of Gunung Rinjani National Park
Abstrak: Aren (Arenga pinnata (Wurmb) Merr.) merupakan tumbuhan multiguna yang memiliki potensi nilai ekonomi dan ekologi yang tinggi. Masyarakat sekitar Taman Nasional Gunung Rinjani banyak yang melakukan kegiatan perekonomian berasal dari hasil tumbuhan aren. Penelitian ini bertujuan mengidentifikasi potensi populasi aren dan bentuk pemanfaatan aren di desa penyangga Taman Nasional Gunung Rinjani. Pengambilan data dilakukan melalui studi literatur, wawancara semi terstruktur dengan metode purposive sampling, observasi lapang, dan analisis vegetasi. Pemanfaatan paling besar terdapat pada bagian bunga jantan untuk penyadapan air nira sebagai bahan baku pembuatan gula aren. Pemanfaatan lain yang dilakukan oleh masyarakat adalah bagian bunga betina untuk menghasilkan kolang-kaling; ijuk untuk pembuatan sapu dan atap rumah; daun untuk pembungkus makanan, pembuatan sapu lidi, dan pembatas lahan; batang mudanya sebagai bahan makanan; serta batang tuanya untuk pembuatan gagang perkakas dan pembatas lahan. Populasi tumbuhan aren di sekitar Taman Nasional Gunung Rinjani termasuk kedalam kategori lestari. Perlu adanya kerjasama antar berbagai pihak dalam pemanfaatan aren untuk meningkatkan nilai komoditas aren., Sugar palm (Arenga pinnata (Wurmb) Merr.) is a multipurpose plant that has high potential economic and ecological value. Many people around the Gunung Rinjani National Park carry out economic activities derived from sugar palm products. This study aims to identify the potential of the sugar palm population and the form of sugar palm utilization in the buffer area of Gunung Rinjani National Park. Data were collected through literature study, semi-structured interviews with purposive sampling method, field observations, and vegetation analysis. The greatest utilization is found in the male flowers portion for tapping the water of nira as a raw material for making palm sugar. Another parts of sugar palm commonly utilized is the female flowers to produce kolang-kaling; fibers used to make brooms and roofs; leaves used to make broomsticks, wrapping food, and land dividers; young stems as food; as well as old trunk for the manufacture of tool handles and land dividers. The sugar palm population around Mount Rinjani National Park is included in the sustainable category. Cooperation between various parties is needed in the use of sugar palm to increase the value of sugar palm commodities.

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.
