Judul: Pemodelan Spasial Kesesuaian Habitat Julang Emas (Rhyticeros undulatus) di Taman Nasional Gunung Halimun Salak
Abstrak: Julang emas (Rhyticeros undulatus) merupakan jenis burung dari Famili Bucerotidae dan termasuk burung frugivora. Resort Cimantaja, Taman Nasional Gunung Halimun Salak (TNGHS) adalah salah satu lokasi persebaran julang emas. Tujuan penelitian yaitu mengidentifikasi variabel-variabel berpengaruh, potensi kesesuaian habitat, dan membangun model kesesuaian habitat di TNGHS. Metode yang digunakan yaitu studi literatur, observasi lapang dan pengamatan vegetasi. Analisis pemodelan habitat julang emas di TNGHS dengan metode analisis spasial menggunakan tujuh variabel meliputi jarak dari pohon pakan, NDVI, tutupan lahan, ketinggian, kemiringan, jarak dari jalan, dan jarak dari permukiman. Hasil penelitian menunjukkan bahwa variabel yang paling berpengaruh terhadap pembangunan model kesesuaian yaitu jarak dari pohon pakan dan tutupan lahan. Luasan terbesar pada lokasi penelitian yaitu kelas kesesuaian sedang yaitu 2627,41 ha dari luas keseluruhan sebesar 3290,20 ha. Karakteristik habitat julang emas di lokasi penelitian meliputi dekat dengan pohon pakan dengan kerapatan tajuk yang rapat, tutupan lahan dengan daerah bervegetasi, daerah ketinggian ≥ 700 mdpl dengan kemiringan lereng yang curam dan jauh dari aktivitas manusia. Kata kunci: analisis spasial, julang emas, habitat, TNGHS, The wreathed hornbill (Rhyticeros undulatus) is a species of bird from the Bucerotidae family and is a frugivorous bird. Cimantaja Resort, Mount Halimun Salak National Park (TNGHS) is one of the locations for the distribution of the wreathed hornbill. The research objectives are to identify influential variables, and potential habitat suitability, and to build a model of habitat suitability in TNGHS. The method used is literature study, field observation, and vegetation observation. Modeling analysis of wreathed hornbill habitat in TNGHS using spatial analysis method using seven variables including distance from forage trees, NDVI, land cover, elevation, slope, distance from roads, and distance from settlements. The results showed that the most influential variables in the development of the suitability model were the distance from forage trees and land cover. The largest area in the research location is the medium suitability class, which is 2627,41 ha of the total area of 3290,20 ha. Habitat characteristics of the wreathed hornbill at the study site include close to foraging trees with dense canopy density, land cover with vegetated areas, and an altitude area of 700 m above sea level with steep slopes and far from human activities.

Judul: Distribusi Habitat dan Karakteristik Lanskap Habitat Elang Jawa (Nisaetus bartelsi) di Taman Nasional Gunung Halimun Salak
Abstrak: Taman Nasional Gunung Halimun Salak (TNGHS) merupakan taman nasional yang memiliki area hutan dataran rendah dan hutan dataran tinggi dalam satu kawasan. TNGHS menjadi habitat persebaran bagi elang jawa (Nisaetus bartelsi) yang merupakan salah satu satwa dilindungi dengan status endangered species. Elang jawa juga dijadikan sebagai maskot TNGHS, sehingga diperlukan informasi mengenai distribusi dan karakteristik lanskap habitat untuk memudahkan kegiatan pengelolaan kawasan. Tujuan dari penelitian ini yaitu melakukan pemetaan dan validasi data distribusi habitat elang jawa di TNGHS, membandingkan karakteristik lanskap habitat elang jawa pada dataran tinggi dan dataran rendah di TNGHS, serta menyusun rekomendasi pengelolaan lanskap habitat elang jawa di TNGHS. Penelitian ini dilakukan dengan mengobservasi lanskap yang menjadi lokasi perjumpaan dan keberadaan pohon sarang, kemudian menganalisis vegetasi, serta melakukan perbandingan antara habitat elang jawa di hutan dataran rendah dan hutan dataran tinggi di TNGHS. Hasil menunjukkan bahwa elang jawa di TNGHS memanfaatkan hutan dataran rendah dan hutan dataran tinggi dengan elevasi, slope, dan karakteristik lanskap yang berbeda antara kedua area hutan. Rekomendasi pengelolaan yang diusulkan yaitu memfokuskan monitoring elang jawa pada habitat preferensi dan lokasi-lokasi yang berpotensi sebagai habitat preferensi elang jawa, mempertahankan kualitas lanskap habitat elang jawa dengan penanaman pohon preferensi pada kegiatan rehabilitasi, optimalisasi kegiatan monitoring elang jawa dengan penambahan fasilitas pendukung, serta meningkatkan kerjasama dengan masyarakat dan stakeholder dalam pengelolaan habitat dan pelestarian elang jawa., Halimun Salak Mountain National Park (TNGHS) is a national park that has an area of lowland forest and highland forest in one area. TNGHS is a distribution habitat for Javan Hawk-Eagle (JHE) which is one of protected animals with an endangered species status. The JHE is also used as the TNGHS mascot, so information about the distribution and characteristics of landscape habitat is needed to facilitate management. This study aims to map and validate data on the distribution of the JHE’s habitat in TNGHS, compare the characteristics of the JHE’s habitat in the lowlands and highlands in TNGHS, and develop recommendations for landscape management of the JHE’s habitat in TNGHS. The research was conducted by observing the landscape where the encounter and the presence of nest trees, then analyzing the vegetation, and making comparison between the JHE’s habitat in lowland forest and highland forest in TNGHS. The results showed JHE in TNGHS utilizes lowland forests and highland forests with different elevation, slope, and landscape characteristics between the two forest areas. The proposed management recommendations are to focus on monitoring the JHE’s habitats preference and locations that have the potential to be the preferred habitat of the JHE, maintaining the quality of the JHE's habitat landscape by planting preferential trees in rehabilitation activities, optimizing monitoring activities for the JHE with the addition of supporting facilities, and increasing cooperation with the community and stakeholders in habitat management and conservation of the JHE.

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.
