Judul: Perencanaan Lanskap Kawasan Wisata Danau Mas Harun Bastari di Kabupaten Rejang Lebong Provinsi Bengkulu
Abstrak: The increase of tourist numbers who visit tourism object reflects that the people realize that they need of recreation. This means that tourism has a bright prospect to develop. The people’s need of tourim object become a challenge to goverment and the another stakeholders to create tourism object that can fulfill it. But in other side tourism activity can make a bad impact for natural environtment and cultural environment. If this situaton last longer can cause damage to the environment that cannot be restored. Tourism object planning is needed to protect, prevent ,and restore the environment from damage that come from tourism activities . The planning of tourism object can overcome the bad impact and make a sustainable tourism object . The purpose of this research is planning a tourism object that can fulfill the need of recreation activity and can be sustainable. The planning object is the Danau Mas Harun Bastari tourism object of Rejang Lebong District. This research is using the environmental aspects as basics foundation for planning the tourism objects. This research took three process which are inventory, analysis and synthesis. Physical and cultural data were gathered in inventory process. Data from inventory were analyzed to make the basics of planning and reveal the potentials and dangers in site. The concept was developed in syhntesis process. The result of this study is a landscape plan.

Judul: Perencanaan pariwisata alam berbasis data spasial di Taman Nasional Bukit Barisan Selatan
Abstrak: The National Park of Bukit Barisan Selatan (TNBBS) was declared as “Cluster Natural World Heritage Site” at 2004. The declaration will support a sustainable nature-tourism utilization. Development of nature tourism at TNBBS is concentrated in Kubu Perahu and Sukaraja Atas area. Objective of the research is to develop a plan of nature tourism based on spatial data. The research proposed application of planning model, proposed by Gunn (1994) which is combined with ADO-ODTWA (Analisis Daerah Operasi Obyek dan Daya Tarik Pariwisata Alam) promoted by PHKA (2003b). Spatial analysis was done with Arcview 3.3. The overlay spatial analysis proposed a prime and support criterias. Prime criteria consist of habitat fragility, soil, rainfall and slope sensitivity, the attraction of nature phenomena and wildlife. Support criteria is the potential accessibility. The result of the spatial analysis showed that Sukaraja Atas and Kubu Perahu have two categories of nature tourism area that is medium intensity tourism area and low intensity tourism area. Sukaraja Atas area have 483.8 hectare (71.2%) of medium intensity tourism area and 195.4 hectare (28.2%) of low intensity tourism area. Kubu Perahu area have 374.9 hectare (32.7%) of medium intensity tourism area and 771.0 hectare (67.3%) of low intensity tourism area.The result of the reoverlay between the classification map and the maps of each criterias showed that the spatial analysis which were used in this research had capability to bounding the tourism development based on resources sensitivity (showed the importance of conservation) and supported the resources potencies to gave the recreational value. Spatial system at Sukaraja Atas and Kubu Perahu had 2 (two) areas, (1) Low intensity tourism area and (2) Medium intensity tourism area. The wide of each areas be the same with the wide of the classification result. The main facility is an interpretation trail that have fungtion as a connector the visitor to the attraction site and inter-site of attraction. The setting of the interpretation trails more priored in the medium intensity tourism area. Development of nature tourism in the areas for low intensity tourism have purpose as a connection interarea for medium intensity tourism and give an attraction opportunity which have special quality for challenge variance. Facility development in the areas for low intensity tourism were finited for an interpretation trail and nature shelter. Trail development in steep areas must pay attention with visitor’s safety with stepsmaking, however the steps must built from nature material and specific wide to minimization soil-clearing and a distrubance to animal movement. The conclution of this researh, first, spatial analysis which were used in this research had capability aimed at the importance of conservation and gave the recreational value. Second, spatial system at Sukaraja Atas and Kubu Perahu consist of the low intensity tourism area and medium intensity tourism area. Third, management variation of nature tourism with spatial system and a plan of facility can make variation of nature-tourism opportunity especially variation of interest, variation of visitors, variation of spend time and variation of interpretation.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
