Judul: The Mechanism of Stakeholder Relations in Ecotourism Hazard Management in Mount Rinjani National Park, Central Lombok Regency
Abstrak: Taman Nasional Gunung Rinjani (TNGR) wilayah Lombok Tengah memiliki keindahan dan potensi alam yang cocok sebagai destinasi ekowisata. Terdapat jalur pendakian Gunung Rinjani di Lombok Tengah yaitu jalur pendakian Aik Berik yang mana jalur ini tidak lepas dari adanya suatu potensi bahaya. Frekuensi kejadian bahaya yang sering terjadi dan tingkat risiko yang beragam membuat pengelolaan tidak mudah dilakukan, maka diperlukan kerja sama para pihak yang bersifat terkordinir dan berjangka panjang. Tujuan dari penelitian ini adalah merumuskan mekanisme hubungan stakeholder dalam pengelolaan bahaya ekowisata. Pengambilan data dilakukan dengan wawancara informan kunci, observasi lapang, dan penelusuran dokumen. Analisis data yang digunakan meliputi analisis stakeholder, analisis isi kebijakan, dan analisis deskriptif. Hasil penelitian ini menunjukan komponen kerentanan dan komponen bahaya pada analisis isi kebijakan ditemukan paling sedikit di dalam dokumen analisis isi TUPOKSI dan aturan kelembagaan masing-masing stakeholder. Kebutuhan stakeholder dikelompokkan menjadi 3 kelompok yang terdiri dari sarana dan prasarana, hubungan, dan peningkatan ilmu pengetahuan dan keterampilan. Rumusan mekanisme hubungan stakeholder dilakukan melalui penguatan kerja sama dengan membentuk Tim koordinasi bahaya ekowisata., Mount Rinjani National Park (TNGR) in the Central Lombok region has natural beauty and potential that is suitable as an ecotourism destination. There is a climbing route for Mount Rinjani in Central Lombok, namely the Aik Berik climbing route, where this path cannot be separated from the existence of a potential danger. The frequency of hazard events that often occur and the various risks make management difficult, so coordinated and long-term cooperation from the parties is needed. The purpose of this study is to formulate a stakeholder relationship mechanism in the management of ecotourism hazards. Data were collected by interviewing key informants, field observations, and document searches. The data analysis used includes stakeholder analysis, policy content analysis, and descriptive analysis. The results of this study indicate that the least component vulnerabilities and hazards in the policy content analysis are found mostly in the TUPOKSI content documents and the institutional rules of each stakeholder. Stakeholder needs are divided into 3 groups consisting of facilities and infrastructure, relations, and increasing knowledge and skills. The formulation of the stakeholder relationship mechanism is carried out through strengthening cooperation by forming an ecotourism hazard coordination team.

Judul: Mekanisme Hubungan Stakeholders dan Pemetaan Bahaya di Jalur Torean, Taman Nasional Gunung Rinjani, Kabupaten Lombok Utara.
Abstrak: Mount Rinjani National Park is a mountain that is popular in climbing tours, the Torean route is one of 6 hiking trails on Mount Rinjani. The Torean route is located in Loloan Village, Bayan District, North Lombok Regency. The potential hazards in the Torean route encourage the involvement of stakeholders, both directly and indirectly, to formulate preventive actions. Stakeholder data processing uses the social network analysis method and hazard mapping uses UNEP guidelines. This study found 14 stakeholders including government agencies, community groups, non-governmental organizations and academics. Mount Rinjani National Park Office is the most influential stakeholder because as a manager and directly involved in making policies on climbing the Torean route. There are 3 hazards on the Torean route, namely physical hazard, biological hazard, human hazard, this can threaten climbers when climbing.

Judul: Pembentukan Tanaman Haploid Ganda dengan Perlakuan Oryzalin Secara In Vitro pada Biji Jagung (Zea mays) Diduga Haploid
Abstrak: BC2 maize purple kernels estimated haploid were resulted from a cross between Bisma variety with haploid inducer line (3490) by backcross. Chromosome doubling to these kernels was done to produce doubled haploid plants (pure lines). This study was conducted to get an in vitro diploidisation method by oryzalin treatment as a chromosome doubling agent, with concentration of 0, 5, 10, and 15 mM for 24 hours on seeds and root of seedlings. Chromosome analysis on the control of purple kernels showed 66.7% of the seeds was haploid and 33.3% was diploid. Oryzalin treatment affected in doubling the chromosome number from haploid to doubled haploid or from diploid to tetraploid. The higher concentration of oryzalin increased the opportunity of chromosome doubling, but increased death rate. Combination of treatment that is most efficient was 5 mM oryzalin on seedling roots that produced the highest number of doubled haploid plants was found by 71.4% with a low mortality rate by 30%. Increasing of the chromosome number caused the growth of the longer canopy length and more number of leaves and the lower stomata density.
