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: Dampak ekologi dan model pengelolaan Taman Wisata Alam Cimanggu, Kabupaten Bandung, Jawa Barat
Abstrak: Cimanggu Nature Recreation Park (Cimanggu NRP) is a nature conservation area which has a protective function as life support systems, preserving species diversity of plants and animals, and can be utilized for the benefit of tourism. Growth in tourist arrivals at Cimanggu NRP cause a threat to the preservation of conservation areas and tourist attraction. This can happens when the utilization of the region exceeds its carrying capacity. The aims of this study to identify tourist characteristic, impact of tourism activities at Cimanggu NRP and develop management model of Cimanggu NRP. The results showed that charateritic of tourist at Cimanggu NRP dominated by young tourist, and have low preception to enviroment. The Cimanggu NRP have a larger carbon stocks than the IPCC's recommendation. Based on phytoplankton diversity index, showed that the station 1 and 3 has lightly polluted while station 2 heavily polluted due to the explosion of phytoplankton population. Based on the makrobenthos diversity index, station 1 has water quality that is still clean/not contaminated, while at stations 2 and 3 lightly polluted. The result of model simulation for 35 years showed the value indicator of the success each scenario as follows: Status quo scenario showed ecological impact index > 1, start at 2015, the target of community participation 4.755 person, management accumulation income 5.644.000.000.000 rupiah, the accumulation of tax 4.419.000.000.000 rupiah and community accumulation incomes 916.000.000.000 rupiah. Conservative scenarios: ecological impact index > 1 start at 2015, the target of community participation is 4.498 person, management accumulated income of is 5.496.000.000.000 rupiah, the accumulation of tax 2.355.000.000.000 rupiah, and the accumulation community income 872.000.000.000 rupiah. Asimilation capacity scenarios: ecological impact index < 1 in 2032 (the end of the simulation) is not exceeded, the target of community participation 5.039 person, management accumulated income 5.754.000.000.000 rupiah, the accumulation of tax 2.466.000.000.000, and the accumulation community income 962.000.000.000 rupiah. (d) economy growth scenarios: ecological impact index < 1 in 2032 (the end of the simulation) is not exceeded,, the target of community participation 5.822 person, mangement accumulated income of 5.582.000.000.000 rupiah, the accumulation of tax 2.620.000.000.000, and the accumulation income Rp. 1.100.000.000.000

Judul: Sintesis kompleks salen Cu/Ni sebagai katalis oksidasi gliserol
Abstrak: Biodiesel sebagai salah satu alternatif pengganti minyak bumi telah menghasilkan produk samping berupa gliserol kasar. Salah satu cara pemanfaatan adalah dengan mengoksidasinya menjadi dihidroksiaseton menggunakan kompleks senyawa salen yang telah dihidrogenasi dengan logam atom pusat Cu dan Ni. Katalis yang dihasilkan dicirikan menggunakan spektrofotometer inframerah transformasi Fourier dan spektrofotometer serapan atom. Kinerja kedua katalis dalam mengoksidasi gliserol telah dibandingkan dengan baik dalam penelitian ini. Oksidasi gliserol dilakukan dengan tambahan katalis sebanyak 5 mol% gliserol dalam campuran gliserol-asetonitril. Reaksi dilakukan dengan melewatkan gas oksigen selama 4 jam pada suhu ruang dalam campuran tersebut. Hasil oksidasi dianalisis menggunakan kromatografi cair kinerja tinggi. Puncak kromatogram dari hasil oksidasi yang muncul setelah menit ke-9 menunjukkan terjadinya perubahan gliserol. Produk oksidasi gliserol diduga memiliki gugus fungsi keton karena nilai Rf-nya lebih besar daripada gliserol, yang menandakan senyawa tersebut lebih nonpolar daripada gliserol. Kromatogram yang diperoleh menunjukkan bahwa aktivitas katalis Cu(salen) mengoksidasi gliserol lebih baik ditinjau dari rendemen produk yang dihasilkan dibandingkan dengan Ni(salen). Oksidasi baik dengan Cu(salen) maupun Ni(salen) menghasilkan satu produk oksidasi.
