Judul: Stakeholder analysis in the hiking program in  Bromo Tengger Semeru National Park
Abstrak: The Mount Semeru hiking program is related to the utilization function of the national park. As the number of visitors increases, it is necessary to have optimal management by involving several groups or stakeholders to implement the hiking program successfully. This study aims to identify stakeholders, identify stakeholder roles, and analyze stakeholder relationships in the hiking program in TNBTS. The data collection methods were used field observation, literature study, semi-structured interviews, snowball sampling, and questionnaires. Data analysis in this study used stakeholder analysis consisting of identification, classification, and stakeholder relationships. The hiking program in TNBTS involves 11 stakeholders called shamans, the community, SAVER (Semeru Volunteer Friends), evacuation team, porter association, guides, street vendors, jeep association, gimbal alas, homestay industry, and BMKG (Meteorological, Climatological, and Geophysical Agency). Stakeholders have roles as key players, subjects, context setters, and crowds. Each stakeholder has a relationship of communication, coordination, cooperation, or all three relationships

Judul: The Role of Stakeholders in the Development of Nature Tourism in Mount Ciremai National Park
Abstrak: Pengembangan wisata alam di Taman Nasional Gunung Ciremai (TNGC) membutuhkan adanya dukungan dari berbagai pihak pemangku kepentingan. Kepentingan dan pengaruh masing-masing stakeholders perlu diketahui untuk mengelompokkan menjadi key player, subject, crowd dan contextsetter dan hasil tersebut untuk merumuskan peranan stakeholders. Tujuan penelitian yaitu mengidentifikasi dan menganalisis stakeholder, menentukan dan menganalisis kategori stakeholder serta merumuskan peran stakeholder. Metode yang digunakan yaitu observasi lapang dan wawancara. Stakeholders yang terlibat dalam pengembangan wisata alam yaitu 16 stakeholder meliputi dua desa penyangga, yaitu Desa Pasawahan dan Desa Bantaragung dan dikelompokkan pada pemerintah pusat, pemerintah daerah, swasta, dan masyarakat. Stakeholder yang teridentifikasi masuk dalam tiga kategori antara lain key player, crowd, dan contextsetter. Stakeholders yang berperan sebagai mitra pelaksana wisata alam merupakan kelompok masyarakat. Balai TNGC merupakan stakeholders kunci yang memiliki peran paling penting dalam pengembangan wisata alam., The development of natural tourism in Mount Ciremai National Park (TNGC) requires the support of various stakeholders. The interests and influence of each stakeholder need to be known to group them into key players, subjects, crowds and contextsetters and the results are to formulate the roles of stakeholders. The research objectives are to identify and analyze stakeholders, determine and analyze stakeholder categories and formulate stakeholder roles. The method used is field observation and interviews. The stakeholders involved in the development of nature tourism are 16 stakeholders including two buffer villages, namely Pasawahan Village and Bantaragung Village and are grouped into the central government, local government, private sector, and community. The identified stakeholders fall into three categories, including key players, crowds, and contextsetters. Stakeholders who act as implementing partners for nature tourism are community groups. TNGC Hall is a key stakeholder who has the most important role in the development of nature tourism.

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.
