Abstrak: Betung Kerihun National Park (BKNP) is conservation area with national park status with stated the decree of Mimistry of Forestry No. 467/Kpts-II/1995 dated September 5, 1995. Traditional community with heterogonous characteristic inhabited the area surrounding the park. The characteristics were seen in the social interaction of the communitty (Dephut 2006).

Judul: Aplikasi Konsep Ekowisata Dalam Perencanaan Zona Pemanfaatan Taman Nasional untuk Patiwisata dengan Pendekatan Ruang (Studi Kasus Wilayah Seksi Bungan Kawasan Taman Nasional Betung Kerihun di Provinsi Kalimantan Barat)
Abstrak: Betung Kerihun National Park had a potencial objects for ecotourism. Existing utilization of Park had to be developed into an ideal productive ecotourism. This research was aimed to evaluate tourism objects, potencial activities of local community and tourism in one of existing running tourism activites of the park . The research was planned a use zone and tourism areas of the section. Use zone and tourism areas were delineated and ground true checked based on (1) area defined traditionally by local people, (2) protected area (3) potency to develop adventure tourisms, (4) potency to develop education with interpretation program. It is concluded that there were intensive use areas of 2.136 ha (10,8 %), general outdoor tourism 4.321 ha (21,8 %), natural environment areas 10.027 ha (50,6 %), wilderness tourism areas 3.250 ha (16,4 %), tradisional aktivities areas 88 ha (0,4 %).

Judul: The Isolation of Silver (Ag) from Fixer Sludge with Electrolysis methode
Abstrak: with the variations concentration, electrode of carbon, and voltages. The aim of research are looking for the easiest and eficient electrolysis. Among of 272.79 ppm of silver (impurities) could be produced from electrolysis fixer which used 300 times maintain the film. For 400, 500, and 600 times electrolysis were produced recently 49.42, 137.04, and 55.22 ppm. Futhermore, it was increased to 220.00 ppm from 700 times. These were possible because of density the solutions. From the electrode of carbon, 68.2222 g Ag (impurities) could be processed from size 14 cm x 3 cm x 3 cm. The next results 41.2050 g and 43.7559 g from the sizes 16 cm x 3 cm x 3 cm and 18 cm x 3 cm x 3 cm. The reasoned of this part any faster reaction on the most litle electrode. By the way, from voltages variation, the processed showed that 47.4575 g of Ag (impurities) could be produced from 11 volt. It’s caused the bigest voltages are also the bigest kinetics power on the reactions. Sampel and product were analized by AAS. Consentration has potential to be indicator, because of the used 700 times was given trend high Ag (impurities) became increase optimally at 11 volt, and much sediment that is 47.4575 g. The best rendemen is 13.33%. The other finding is that the strength of the time and the voltages strongly enfluence the electrolysis shown by the bigger result on F(calculation) than that of the F(table).
