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: Hazard Mapping in Sembalun-Senaru HIking Trails, Mount Rinjani National Park
Abstrak: Kegiatan pendakian merupakan wisata utama di Taman Nasional Gunung Rinjani (TNGR). Gempa yang terjadi pada Agustus 2018 berdampak pada perubahan lanskap di jalur pendakian. Penelitian ini bertujuan mengidentifikasi, menilai dan memetakan potensi bahaya serta menyusun rekomendasi manajemen bahaya di jalur pendakian Sembalun-Senaru TNGR. Data dikumpulkan melalui observasi lapangan, wawancara dan studi pustaka. Analisis data bahaya fisik dan biologi mengacu United Nation Environment Programme (UNEP) sedangkan data bahaya aktivitas manusia mengacu National Patient Safety Agency (NPSA). Jenis bahaya yang ditemukan adalah tanah longsor, aktivitas gunung berapi, kebakaran, jurang, jalur curam, suhu rendah, kabut, satwa liar, bahaya tanaman dan aktivitas manusia. Jenis bahaya dengan nilai resiko tertinggi yaitu jalur terjal (fisik), akar pohon (biologis) dan berlari (manusia). Penanganan bahaya melalui tindakan preventif dilakukan dengan meningkatkan pengetahuan pendaki dan masyarakat melalui edukasi mengenai bahaya, peningkatan kualitas serta penambahan infrastruktur pendukung. Tindakan kuratif dilakukan dengan menetapkan standar operasional yang jelas untuk proses penanganan kecelakaan dan evakuasi. Kata kunci: jalur pendakian, manajemen bahaya, pemetaan potensi bahaya, Mountaineering activities are the main tourism in Mount Rinjani National Park (MRNP). The earthquake that occurred in August 2018 had an impact on changing the landscape on the hiking trail. This study aims to identify, assess and conclude potential hazards and develop recommendations for hazard management on the Sembalun-Senaru hiking trail in MRNP. The data was collected through field observations, interviews and literature study. Analysis of physical and biological hazard data refers to the United Nation Environment Program (UNEP) while human activity hazard data refers to the National Patient Safety Agency (NPSA). The types of hazards found are landslides, volcanic activity, fire, ravines, steep paths, low temperatures, fog, wildlife, plant hazards and human activities. The types of hazards with the highest risk values are steep paths (physical), tree roots (biological), and running (human). Handling hazards through preventive measures is carried out by increasing the knowledge of climbers and the public through education regarding hazards, improving quality and adding supporting infrastructure. Curative action is carried out by setting clear operational standards for the process of handling accidents and transportation. Keywords: hazard management, hiking trails, mapping potential hazards

Judul: Estimation of Additive and Non-Additive Genetic Variances of Body Weight, Egg Weight and Egg Production for Quails (Coturnix coturnix japonica) with an Animal Model Analysis
Abstrak: This study estimates the additive and non-additive variances for egg production and body weight traits of two lines of quails from a long-term selection with the help of the REML method. For the body weight of 42-day-old females (BW42f) and males (BW42m), a total of 7,934 records for line 1 and 7,214 records for line 2 from 21 generations were used in our analyses. Additionally, 1,717 records of females from line 1 and 1,671 records of females from line 2 contained information on their egg production at an age of 42 to 200 days (EN200), on the average egg weight for the first 11 weeks of their laying season (EW1), on the average egg weight from weeks 12 to 23 (EW2), and on their body weight at an age of 200 days (BW200f). A multivariate additive animal model and one-trait dominance models, which include the inbreeding coefficients as covariates, were fitted to the data. The estimates of the heritability gained from our dominance models were smaller than those from the additive model. For line 1, the heritability values decreased for EN200 from 0.35 to 0.32, for EW1 from 0.66 to 0.56, for BW200f from 0.42 to 0.38, and for BW200m from 0.51 to 0.49, respectively. For the first line, the respective ratio (d2) of the dominance variance to the phenotypic variance for EN200, EW1, BW200f and BW200m was 0.08, 0.22, 0.09 and 0.21, and the values for the second line were 0.12, 0.06, 0.001 and 0.23.
