Judul: Manajemen Bahaya di Jalur Pendakian Sembalun-Senaru, Taman Nasional Gunung Rinjani, Nusa Tenggara Barat.
Abstrak: Kegiatan pendakian di Gunung Rinjani (3726 mdpl) merupakan wisata yang populer di Taman Nasional Gunung Rinjani. Kegiatan tersebut berpotensi menimbulkan bahaya bagi keselamatan pengunjung. Tujuan penelitian ini adalah membuat manajemen bahaya dengan mengidentifikasi berbagai potensi bahaya berdasarkan aspek fisik, biologi dan aktivitas manusia. Penelitian dilakukan pada bulan April 2018. Data dikumpulkan melalui observasi lapang, wawancara dan studi pustaka. Analisis data bahaya fisik dan biologi mengacu United Nation Environment Programme (UNEP) sedangkan bahaya aktivitas manusia mengacu National Patient Safety Agency (NPSA). Potensi bahaya dengan nilai risiko tertinggi yaitu jurang (fisik), akar pohon (biologi), dan berlari (aktivitas manusia). Opsi manajemen bahaya yang dapat diterapkan yaitu menghindari, menerima, mengurangi, dan memindahkan risiko. Manajemen bahaya dilakukan melalui tindakan preventif, dengan meningkatkan pengetahuan masyarakat dan pengunjung terhadap jenis dan lokasi bahaya, serta tindakan represif, dengan penanganan potensi bahaya yang menyebabkan kecelakaan atau bencana alam.

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: Membran Komposit Kitosan-Zeolit untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Direct methanol fuel cell (DMFC) is a fuel cell that utilize methanol as the fuel source. The electrolyte membrane used in the DMFC system in this research was chitosan-zeolite composite membrane. The composite membrane was synthesized with chitosan-zeolite composition variation of 1:1, 1:2, 1:3, and 2:1. The membranes were analyzed by Fourier transform infrared spectrophotometer (FTIR) and scanning electron microscope, and for the specific gravity. Membrane performances were tested with methanol uptake, methanol permeability, conductivity, and potential difference in the DMFC system. The FTIR spectrum showed no formation of new functional groups inducating that the composite membrane was a result of physical mixing. Morphological analysis showed that the membrane was nonporous. Chitosan-zeolite 1:3 composite membrane had the highest specific gravity and methanol uptake, 1.4226 g/mL and 41.44%, respectively. The highest proton conductivity was showed by the 1:2 chitosanzeolite composite membrane, namely 7.2946× 10-7 S/cm. Based on this research results, chitosan-zeolite composite membrane can be applied in DMFC system.
