Judul: Ekologi Morel Rinjani (Morchella aff. deliciosa) di Taman Nasional Gunung Rinjani-Nusa Tenggara Barat
Abstrak: Ecologically based information on Rinjani morel mushroom (Morchella aff. deliciosa) habitat is needed to determine decision making by park manager for its conservation. The study was taken to describe and identify the ecological factors that correlate with the presence of the fruitbodies of M. aff. deliciosa. Fourteen plots (10m x 10m) with morel fruitbodies and twenty one plots without morel fruitbodies at higher level of altitude were established accidentally for measurement of climatic, soil, and trees variables during morel fructification. Data were described statistically and analyzed using multiple linear regression and discriminant analysis. The research result showed that fructification of M. aff. deliciosa appeared at level of altitude 1572,00-1609,00m, slope between 7,94- 54,00%, aspect between 4,00-360,00o. The lifespan of morel fruitbodies between 15-20 days. The air temperature range of 18,53 - 19,6oC and 83,00 - 90,50% humidity on the forest floor measurement, light between 490,00-620,00lux. Brown Mediterran loam soils supported the morel fruiting, pH neutral (7,0), medium C/N ratio (12,16), low P (12,53ppm) and medium Ca (10,22me/100g). Anomianthus auritus, Syzygium polyanthum, Weinmannia sp., Uropyhllum macrophyllum, and Piper sp. were identified as dominant tree species. The values of Shannon-Wiener index obtained for site with morel and site without morel tested using t test (Levene’s test) showed there is no difference in tree diversity between the two locations. The Morisita–Horn index also showed that similirity indices between the two locations is about 83,40%. The research result indicated that morel started to fruit when the humidity begin to slow for some short period and stopped to fruit until humidity constant relatively. The multiple linear regression analysis showed that light was the only ecological factor correlated significantly with the number of morel fruitbodies. Meanwhile the t test showed there was significantly different ecological components between the morel site and the site without morel i.e the temperature, forest floor moisture, light intensity and altitude factor. This information on the nature M. aff. deliciosa habitat provides the first step in succesfull management and conservation of morel and other mushroom resources.

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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
