Judul: Dinamika dan Konfigurasi Kepentingan di Balik Pemaknaan terhadap Burung Berkicau di Jawa (Kasus di Surabaya dan Yogyakarta)
Abstrak: Penelitian ini dilakukan atas dasar beberapa argumentasi. Pertama, burung memiliki peran yang cukup penting dalam kehidupan manusia dalam aspek ekonomi, ekologi, sosio-kultural dan ekologis. Kedua, terdapat gejala semakin meningkatnya kegemaran memelihara burung dikalangan masyarakat Jawa yang ditandai dengan semakin banyaknya komunitas penggemar burung dan kegiatan-kegiatan yang berkaitan dengan burung. Ketiga, meningkatnya kegemaran terhadap burung memberikan implikasi terhadap semakin terancamnya beberapa jenis burung di alam karena kegiatan perburuan dan perdagangan burung. Keempat, telaah terhadap peran aktor (manusia) dalam permasalahan menjadi salah satu fokus kajian yang penting dalam mengkaitkan antara permasalahan keterancaman burung di alam dengan perkembangan komunitas penggemar burung.

Judul: Dinamika dan Konfigurasi Kepentingan di Balik Pemaknaan terhadap Burung Berkicau di Jawa (Kasus di Surabaya dan Yogyakarta)
Abstrak: This research have aim to explain about the tipology of birdkeepers community in Surabaya and Yogyakarta. The second is explain about the kinds of social construction in birdkeepers community in Surabaya and Yogyakarta and the third is to expalin the dynamic and interest configuration behind the social construction of songbird in birdkeepers community in Surabaya and Yogyakarta. In Surabaya and Yogyakarta, the tipology of birdkeeping organization and the birdkeepers commnuity is different one and another. This is because the socio-cultural setting in Surabaya and Yogyakarta is very different to representation the Java’s culture. This condition have some implication for the social construction in birdkeepers community in Surabaya and Yogyakarta. In Surabaya the economyc and commercial dimention of social construction is very dominated more than socio-cultural and conservation dimention. This condition is because in the historical aspect Surabaya is some of the city in Java became a center of economyc activity. The condition in Yogyakarta is very different with Surabaya, In Yogyakarta social construction of songbird in birdkeepers community dominated by socio-cultural dimention. The argument of this condition is because Yogyakarta in the historical aspect is a some of the city in Java became center of Java’s Kingdom with the traditional culture. The interpretation of the songbird in the birdkeepers community in Surabaya and Yogyakarta on the some aspect is dependent of interest configuration in outside of birdkeepers community. The interest configuration is a representation of actor-actor in outside area of birdkepeers community with have some interest to the activity of birdkeepers organization and the community. The dinamyc of social cosntruction in the birdkeepeers community is representation of interest configuration actor-actor. This is condition explain if actors role is very important dependent of songbird interpretation in Java’s society’s

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.
