Judul: Hornbills (Family Bucerotidae) Tourism Plan at Harapan Rainforest Batanghari Regency, Jambi Province
Abstrak: Harapan Rainforest is forest ecosystem restoration in areas of former production forest which still has biodiversity and potential to be used as objects and tourist attractions which could give ecotourism opportunities as an alternative economic income. Hornbills (Bucerotidae Family) could be the object for tourist attraction. This study was aimed to develop hornbills tourism plan at the site level. Activities undertaken to develop a tourism plan were to inventory the distribution of hornbills area (distribution of nests, feeding places and flying path) and other animals as additional tourist attraction. Behavior of hornbills at the time of eating, flying and nesting was also studied. The expected result were recommendations to develop tourism plan at the site focusing on hornbills, alternative solutions for Harapan Rainforest’s and the local community’s income, and conservation of habitat and population of hornbills. Data were collected in the form of primary and secondary data. Primary data included wildlife data and the descriptions related to the site. Data parameters included the wildlife species, activities, time and date of the activities, location, weather, number of individuals, natural nests and artificial nests of hornbills. The site description included the accessibility of the area, infrastructure and management of ecotourism. Secondary data included tourism management data which included organizational structure, general work plan for tourism planning division, and management systems of habitat and hornbills population. Tourism was developed based on the existing hornbill species, hornbill behavior, management plan, and input from various stakeholders the parties. Tourism plan was divided into two categories: casual tourism and special interest tourism. Casual tourism was observing hornbills flying and other wildlife attractions, whereas special interest tourism was observing feeding and nesting behavior. Casual toursim could be done in June – September for a minimum visit of three days. Special interest tourism of flying and eating attraction could be done in September – December for a minimum visit of four days, whereas. Special interest tourism of nesting behavior could be done in January – Mei for a minimum visit of four days. The duration of observation time would be four hours, 2 – 3 visitors for every observation. Technical matters which need to be considered by tour operator were the distance from visitor to avoid disturbance, quota of visitors, standard operating procedures of visitor’s ethic codes, the guide’s ethic codes and the equipment used at the time of observation.

Judul: Management and Economic Valuation of Rhinoceros Hornbill in Bird Park TMII
Abstrak: Rangkong badak banyak diburu oleh masyarakat karena memiliki nilai ekonomi yang tinggi. Salah satu upaya untuk mengurangi kepunahan spesies akibat perburuan adalah dengan melakukan konservasi ex situ. Penelitian ini bertujuan untuk mengidentifikasi aspek pengelolaan rangkong badak (Buceros rhinoceros) secara ex situ dan menghitung nilai ekonominya berdasarkan biaya pemeliharaan dan willingness to pay pengunjung Taman Burung TMII untuk memelihara dan memanfaatkan rangkong badak sebagai satwa peraga. Hasil penelitian ini menunjukkan rangkong badak di Taman Burung TMII belum mengalami perkembangan jumlah individu karena belum terjadi perkawinan. Seluruh aspek pengelolaan yang dilakukan sudah cukup baik. Akibat pandemi Covid-19, jumlah tenaga kerja lapang dikurangi sehingga menyebabkan pekerjaan yang dilakukan menjadi lebih banyak. Nilai ekonomi rangkong badak berdasarkan biaya pemeliharaan yang dikeluarkan setiap bulannya sebesar Rp 2.620.000. Nilai ekonomi berdasarkan willingness to pay dari pengunjung untuk memelihara rangkong badak sebesar Rp 1.064.737 per ekor dan untuk pemanfaatan sebagai satwa peraga sebesar Rp 15.105., Rhino hornbill is hunted by many people because of its high economic value. One of the efforts to reduce the species extinction due to illegal hunting is to carry out an ex situ conservation. This study aims to identify the aspects of ex situ management of rhino hornbill (Buceros rhinoceros) and calculate its economic value based on maintenance costs and 'willingness to pay' by the visitors of TMII Bird Park to take care and use rhino hornbill as a display animal. The results of this study indicate that the individuals number of rhino hornbill in the TMII Bird Park has not increasing because there has not been any mating. All aspects of management carried out are quite good. Due to the Covid-19 pandemic, the number of field workers has been reduced, causing more work to be done. The economic value of the rhinoceros hornbill is based on the monthly maintenance costs of IDR 2,620,000. The economic value based on the willingness to pay by the visitors to take care rhino hornbill is IDR 1,064,737 per individuals and for the use of display animals is IDR 15,105.

Judul: Methanol Permeability on Membrane Electrode Assembly Chitosan-Sulfonated Polysulfone Composite
Abstrak: Sel bahan bakar dianggap sebagai solusi dalam permasalahan krisis energi. Penggunaan membran elektrolit berbasis polisulfon (PSf) pada direct methanol fuel cell (DMFC) telah meluas karena harganya yang murah dan dapat dioperasikan pada suhu tinggi, namun hidrofilisitasnya rendah. Kitosan mampu meningkatkan hidrofilisitas PSf karena adanya gugus -OH dan -NH2. Penelitian ini bertujuan membuat membrane electrode assembly (MEA) berbasis komposit PSf tersulfonasi (sPSf)-kitosan dan mengkaji pengaruh modifikasi membran dan konsentrasi metanol umpan terhadap permeabilitas membran. Pembuatan MEA berhasil dilakukan dan dibuktikan dengan terbentuknya lapisan katalis karbon melalui analisis scanning electron microscope (SEM). Penambahan kitosan dengan konsentrasi tertinggi (5%) meningkatkan water uptake sebesar 586,34%. Membran sPSf-kitosan 5% pada metanol 20% menghasilkan permeabilitas terendah, yaitu sebesar 1,86 × 10-7 cm 2 ·s -1 . Kajian ini membuktikan bahwa penambahan kitosan dan konsentrasi metanol umpan yang pekat akan menurunkan nilai permeabilitas membran.
