Judul: Ecological and Psychological Carrying Capacity of Tourism in Themepark, Case Study: Taman Wisata Matahari, Cisarua Bogor.
Abstrak: The research aims to analyze the maximum number of tourists who can be accepted by Taman Wisata Matahari (TWM) site without creating environmental changes that cannot be accepted and/or without reducing the quality of tourist experience. Cifuentes methods used in analyzing the ecological carrying capacity, while the results of Importance-Performance Analysis and Customer Satisfaction Index Analysis used to elaborate the ecological carrying capacity with the tourist psychological carrying capacity. The intensity of use gives a different effect on several ecological factors of the site. The significant differences indicated by variable of water content of soil, penetration of soil and quality of plants (density, texture, length and productivity). The density of sites affects the tourist satisfaction significantly only in the low visits, but does not apply to the tourist satisfaction in the condensed and peak visit. Nonetheless, the CSI value of all visit types was still in the range between somewhat satisfied to satisfied. Each tourist only uses space about 1.08 m2 /tourist on the block A1 (ground recreation). They only need narrow space because they dominantly come with family and motivated to do social interaction. Both reasons are allegedly caused high levels of tolerance in accepting the presence of other tourists. In block A2 (water recreation) and A3 (artificial exploring recreation), each area can accommodate about 4 756 and 986 tourist/day. Based on the tourists’ space needed on the block A1 and the quota of block A2 and A3, the value of the physical carrying capacity of TWM are 129 904 tourist/day. Ecological carrying capacity of TWM is obtained after reduced by correction factor of soil (26.75%), correction factor of steam flow (1.04%), and correction factor of grass (7.56%), so the value are 87 043 tourist/day. Ecological carrying capacity was not exceeded the carrying capacity of tourist psychology when considering the value of CSI in each period of visit type is still in the range of somewhat satisfied.

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: Prenilasi Senyawa β-Diketon sebagai Prekursor 3-Prenilflavon
Abstrak: One group of flavonoids that has not been commonly synthesized is 3- prenylflavone. The main objective of this experiment was to synthesize precursor of 3-prenylflavone. Firstly, β-diketone was synthesized via 4 steps from phenol as starting compound with total yield of 24%. Prenylation of β-diketone with prenyl bromide and K2CO3 base produced 4 fractions which were separated by using preparative thin layer chromatography (PTLC) with n-hexane:EtOAc (8:2) as the eluent. Fraction with Rf = 0.80 was further separated by using preparative PTLC with n-hexane:EtOAc (99:1) as the eluent. Two fractions were obtained with Rf = 0.38 and 0.42. The first fraction has been characterized as diprenylated β-diketone with 49% yield. Application of protecting group on the phenolic OH group in β- diketone are needed to obtain monoprenylated β-diketone which can be further cyclized into 3-prenylflavone
