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: Membran polistirena dengan ragam suhu perendaman untuk pervaporasi alkohol
Abstrak: Polystyrene membrane with PLURONIC as porogen, can be utilized in alcohol pervaporation. The polystyrene membrane was made by reverse phase method which was started with making of polymeric mixed solution between polystyrene and PLURONIC in dichloromethane with 2 different compositions, i.e.-polystyrene :PLURONIC:dichloromethane 17:0:83 and 17:1:82. The solution was stirred up for 5 hours with ultrasonic and casted on the glass plate surface, and then it was immersed into water at 40, 50, and 60 oC. The highest pervaporation result was 90,2% alcohol purities at 50 oC immersion temperature. However, this result was not good enough because the alcohol purities was lower than the standard alcohol purities at 91,6%.
