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: Pengelolaan Lanskap Untuk Kegiatan Wisata Birdwatching Elang Jawa (Nisaetus bartelsi) Di Taman Nasional Alas Purwo
Abstrak: Elang Jawa (Nisaetus bartelsi) merupakan raptor endemik Pulau Jawa yang terancam punah. Elang jawa tersebar di hutan dataran tinggi dan hutan dataran rendah. Taman Nasional Alas Purwo (TNAP) merupakan habitat elang jawa di hutan dataran rendah. Elang jawa merupakan satwa kunci TNAP yang harus ditingkatkan upaya konservasinya. Wisata birdwatching merupakan cara konservasi elang jawa di TNAP dengan pemanfaatan berkelanjutan. Tujuan penelitian ini adalah pemetaan perjumpaan elang jawa dan menganalisis karakteristik preferensi habitat berburu dan habitat bersarang, menganalisis potensi pengembangan wisata birdwatching elang jawa, dan memberikan rekomendasi pengelolaan lanskap untuk kegiatan wisata birdwatching elang jawa. Data dikumpulkan dengan teknik observasi habitat berburu dan bersarang, literatur, wawancara pengelola, dan kuisioner pengunjung yang digunakan untuk analisis lanskap, analisis vegetasi, analisis pohon sarang, dan analisis SWOT. Hasil menunjukan elang jawa ditemukan di Seksi Pengelolaan Taman Nasional (SPTN) 1 Tegaldlimo dan SPTN 2 Muncar dengan pemanfaatan hutan alami yang tinggi. Kondisi habitat bersarang dan berburu ditemukan pada slope datar hingga curam dengan elevasi 0-167 mdpl serta sekitar sarang ditemukan sungai. Vegetasi pakan mangsa elang jawa strata A dan B dengan keragaman sedang ditemukan pada habitat berburu dan bersarang. Bendo (Arthocarpus elastica) menjadi pohon sarang karena memiliki model arsitektur rauh, strata A, dan emergent tree. TNAP memiliki potensi mengembangkan wisata birdwatching elang jawa. Namun, dengan kondisi fasilitas kurang mendukung dan infromasi terbatas. Kondisi tersebut menghasilkan rekomendasi berupa perencanaan wisata birdwatching elang jawa, restorasi habitat menggunakan preferensi vegetasi di TNAP, melakukan promosi dengan berbagai media, serta bekerjasama dengan stakeholders terkait., Javan Hawk-Eagle, JHE (Nisaetus bartelsi) is an endemic raptor in Java Island with endangered status. JHE are spread in highland forests and lowland forests. Alas Purwo National Park (APNP) is JHE habitat in lowland forests. JHE is a key animal in APNP must be improved in conservation efforts. Birdwatching is way of JHE conservation in APNP with sustainable use efforts. Purpose of this study was to map JHE encounters and analyze the characteristics of hunting and nesting habitat preferences, analyze the potential for developing JHE birdwatching tourism, and provide recommendations landscape management for JHE birdwatching tourism. Data obtained from observations in hunting and breeding habitats, literature, interviews to maintener, and questionnaires to tourists which were used for landscape analysis, vegetation analysis, nest tree analysis, and SWOT analysis. The results is JHE was found in the National Park Management Section (NPMS) 1 Tegaldlimo and NPMS 2 Muncar with high utilization of natural forests. Nesting and hunting habitat were found at 0-167 MASL and flat to steep slopes and around the nest found river. Prey vegetation of JHE has strata A and B was found in hunting and nesting habitats with moderate diversity. Bendo (Arthocarpus elastica) were a nest tree because it had an rauh architecture model, strata A, and emergent tree. TNAP has potential to develop JHE birdwatching tourism. However, the condition of facilities was not supportive and information was limited. These condition resulted recommendations in the form of planning JHE birdwatching toursim, Habitat restoration using vegetation preferences in APNP, promotions with various media, and collaborating with related stakeholders.

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%.
