Judul: Dampak Penetapan Taman Nasional Gunung Halimun Salak terhadap Masyarakat Kasepuhan Cipta Mulya
Abstrak: Kasepuhan Cipta Mulya people faced change of forest function which is their life source. Forest that they use for many years in production forest status changed into conservation forest that limiting human activity inside. That point caused change of Kasepuhan Cipta Mulya people’s access of customary forest. Otherwise, households’ livelihood activity and income not too affected by determination of Gunung Halimun Salak National Park (TNGHS). Moreover, most of Kasepuhan Cipta Mulya people have neutral attitude about TNGHS’ determination. There is moderate significant correlation between attitude and owning status of used land. Otherwise, there is weak positive correlation between attitude and amount of used land. Moreover, attitude and households’ income have weak positive correlation.

Judul: Pengaruh peubah sosial ekonomi terhadap perubahan penggunaan dan penutupan Lahan di Taman Nasional Gunung Halimun Salak
Abstrak: Gunung Halimun Salak is one of national park in Indonesia, located in West Java and Banten Province. In 2003, government has expanded its area by more than 70000 hectares. It caused a lot of conflicts between local communities and national park officials. Many case studies showed that the local communities has used the natural resources for construction materials, fuel wood, medicine, food, cultural needs, forages, hunting, handicraft, gold mining, agriculture land, and settlement. There was clear evidence that in Gunung Halimun Salak National Park, during 15 years period (1989-2004), forest cover area decreased by more than 25%. The objectives of the research are: 1) to identify socio-economic variables causing landuse and landcover change; 2) to estimate influence of key socio-economic variables; 3) to estimate the need of agricultural land and settlement for local communities; and 4) to estimate the direct benefit value of the national park. Selection of sampling location was used by stratified cluster sampling. Socio-economic data collected from interviews with 900 head of households which lived in 30 villages in and around the national park. The technique of data processing analysis were done using spatial analysis, descriptive analysis, linear regression analysis, population pressure analysis, and substitution and market price analysis. The result of analysis showed that the population growth, population density, land ownership, agricultural land and settlement expansion are the key variables that influenced landuse and landcover change. The need of agricultural land was 0.54 hectares per person, and the direct benefit value of the national park was more than IDR 237 billion per year.

Judul: Proses fermentasi Fed-Batch untuk produksi dekstranase dari isolat bakteri Streptococcus sp. B7
Abstrak: Penelitian ini bertujuan untuk mengembangkan teknik fermentasi pada produksi enzim dekstranase dari isolat bakteri Streptococcus sp B7 dengan mempergunakan sistem fermentasi fed-batch. Fermentasi fed-batch produksi dekstranase dilakukan pada fermentor kapasitas 2 liter dengan laju penambahan substrat 19 ml/jam dengan waktu fermentasi 3 kali 24 jam. Perlakuan yang dilakukan pada penelitian ini adalah pH dan kecepatan putaran. Perlakuan pH dilakukan pada pH 7 dan pH 8, sedangkan kecepatan putaran yang digunakan adalah 300 dan 500 rpm. Aktivitas relatif tertinggi dari semua perlakuan dicapai pada fermentasi dengan kecepatan putaran 500 rpm pada pH 8 yang mencapai 920 U/ml. Hasil terbaik ditinjau dari parameter kinetik terten- tu adalah sebagai berikut: produksi 920 U/ml, produktivi- tas 16.43 U/ml/jam, aktivitas spesifik 17.78 U/mg pro- tein, Yp/x 696.97 U/g sel dan produktivitas spesifik 12.45 U/g sel/jam.
