Judul: Daya Dukung Biofisik Wana Wisata dan Rest Area Urug Kota Tasikmalaya
Abstrak: Wana Wisata and Rest Area Urug, a tourism and recreation area with 6 ha coverage, was once a production forest area of managed by KPH Tasikmalaya. KPH Tasikmalaya managed the area in cooperation with the local government of Tasikmalaya City, and Padepokan Garuda Paksi. The development of Wana Wisata and Rest Area Urug provides positive impact of the increasing number of visitors and job opportunities, but on the other side uncontrollable increase of number of visitors is posing a threat in triggering a decline in the resource’s quality. Therefore, the development of this area should consider it’s resources suitability and carrying capacity. The results showed that tourism suitability index of four tourism activities conducted in the area, i.e. relaxing, out bound, camping, and paint ball, fell into appropriate category, while off road activity fell into appropriate with pre requisite category. The study also showed that the average number of visitors in March was 30 people a day, much lower than the area’s carrying capacity of 2611 people a day. It means that the management still have the opportunity to increase visitor number through various expansion programs.

Judul: Analisis Finansial dan Ekonomi Pengembangan Taman Wisata Alam Telaga Warna Sesuai Daya Dukung Kawasan
Abstrak: Nature Tourism Park (TWA) of Telaga Warna is one of the conservation areas which has the potential for development in terms of visitors and beauty. To achieve optimal development potential and overcome limited funds in the area management, on the basis of goverment regulation year 1984 on the exploitation of nature tourism, in 2003 the Natural Resources Conservation Agency (BKSDA) was patnered with PT LDK to develop the area of TWA Telaga Warna. The development of TWA Telaga Warna provides positive impact in the increased number of visitors, but on the other hand, an uncontrollable increase in the number of visitors is feared to trigger a decline in the resource quality. The development of Telaga Warna requires a study of area carrying capacity so that do not exceed the carrying capacity. Moreover, an economic analysis is required to measure the positive and negative impacts during the tourism are development, especially for the surrounding ecosystem. The study results show that the condition of TWA Telaga Warna is still far below the area carrying capacity threshold. While the result of economic feasibility of TWA Telaga Warna development is economically feasible, meaning that development of the area provides does not endanger the sustainability of natural resources and many benefits for provides, society and ecosystems.

Judul: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
