Judul: Distribution and Habitat Use of Javan Hawk-Eagle and Changeable Hawk Eagle at SPTN I Kuningan, Taman Nasional Gunung Ciremai
Abstrak: Keberadaan elang jawa dan elang brontok di TNGC menghadapi berbagai macam ancaman seperti kerusakan habitat akibat kebakaran hutan dan perdagangan burung ilegal. Belum banyak penelitian dilakukan di TNGC terutama terkait elang jawa dan elang brontok. Penelitian ini bertujuan untuk mengidentifikasi sebaran dan penggunaan habitat elang jawa dan elang brontok di TNGC. Data yang dikumpulkan meliputi titik perjumpaan, perilaku, komponen habitat yang digunakan, dan kondisi habitat yang meliputi komponen vegetasi dan komponen mangsa pakan. Pola sebaran elang jawa terkelompok pada tiap tipe habitat, sedangkan elang brontok hanya ditemukan di habitat hutan alam dengan pola sebara terkelompok. Faktor yang memengaruhi yaitu strategi hidup dan kelimpahan sumberdaya di lokasi pengamatan. Pohon sarang yang digunakan elang jawa yaitu pohon kedondong hutan yang termasuk pohon strata A, batang dan cabang yang kokoh, dan tajuk yang tidak terlalu rapat. Pohon istirahat yang digunakan elang jawa dan elang brontok berguna untuk menyimpan energi dan sebagai tempat untuk berjemur serta berteduh. Jenis mangsa potensial berasal dari mamalia dan burung. Jenis mangsa preferensi bagi elang jawa dan elang brontok yaitu tupai hitam dan lutung jawa., JHE and CHE in TNGC face various threats, such as habitat destruction due to forest fires and illegal bird trade. Not much research has been done in TNGC, especially regarding JHE and CHE. This study aims to identify the distribution and habitat use of JHE and CHE in TNGC. Data that being collected are meeting points, behavior, habitat components used, and habitat conditions which included vegetation components and feed prey components. The distribution pattern of JHE is clustered in each habitat type, while CHE is only found in natural forest habitats with a clustered distribution pattern. The influencing factors are the strategy of living and the abundance of resources at the observation site. The nest tree used by JHE is the Spondias pinnata which includes strata A trees, sturdy trunks and branches, and a canopy that is not too tight. The resting tree used by JHE and CHE is useful for storing energy and as a place for sunbathing and shelter. The types of potential prey come from mammals and birds. Preferred prey types for JHE and CHE are squirrels and langurs.

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: Pervaporasi Alkohol Menggunakan Membran Polistirena-SDS
Abstrak: Polystyrene (PS) membrane with SDS as porogen can be utilized as a filter in alcohol pervaporation process. The membrane was prepared using inversed phase method with PS:SDS:dichloromethane solvent composition were 17:0:83; 17:0.5:82.5; 17:1:82; 17:1.5:81.5; and 17:2:81. Homogenization of mixtures were carried out for 10 and 20 hours and casted on glass plate surface then submerged it into water with temperature of 60 °C. Pervaporation capability was evaluated from flux value and separation factor. The average of water flux values in 20 hours sonication were higher than the values in 10 hours sonication. The highest separation factor was observed in PS membrane with 0.5% SDS concentration and homogenization in 20 hours is 5.23. Application of PS membrane in pervaporation as showed by purities of alcohol value using gas chromatography method revealed that the purities increase from 91.6 to 93.4%. Therefore, certain SDS addition can increase the performance of PS membrane in alcohol purification.
