Judul: Potensi Pengembangan Wisata di Ngalau Antabuang Indah Nagari Sisawah Kabupaten Sijunjung Sumatera Barat
Abstrak: Cave (Ngalau) is one of the natural formations in the karst region that was mostlyattract visitor. Antabuang Indah Cave was once opened then wereclosed in early year 2000 due to destruction of cave environment by visitor. The purpose of this study were to assess the potential of Antabuang Indah cave and its surrounding areas. The potential in Antbuang Indah cave were variety of formations of aisle, cave ornament, and the cave fauna. While the potential of surrounding area include rice fields, forests, rivers and karst cliffs. Social cultural potential that can be toursm package in Ngalau Antabuang Indah was Randai, Pencak Silat and Kaji Balenggok. Visitors expected good management. Activities that can be done in Antabuang Indah cave and its surrounding area was mass tourism and special interest tourism activities.

Judul: Kajian Kondisi Gua untuk Pengembangan Wisata Minat Khusus di Kawasan Karst Gudawang, Kabupaten Bogor
Abstrak: Intensive exploitation in Karst such as mining is damaging the area. On the other hand, karst possesses essensial values for human life, including ecological, economical, social and culturals. One from of conservation effort in karst, which can give benegit to local people and karst itself is ecotourism. Ecotourism development in Karst Gudawang can be to the form of special interest. This study was conducted in Karst Gudawang, Kampung Cipinang, Village Argapura, Cigudeg district, Bogor. Regency 3 months (December 2006 to February 2007). Methods use for foward method for cave mapping, interviews and field abservations for are tourism potential. Tourism analyses criteria consist of interest, climate, accessibility, infrastructure, facility, orher tourism objects, safety, caryying capacity area, tourist regulation and clean water surrounding apply. Special interest concept development in Gudawang ae adventures and education essentialy. There are 3 classification of caves for developing special interest, very suitable, sutable and unsuitable. The very suitable caves to be developed are Si Aul Tengah, Si Parat 2 and Si Garaan. The sitable caves are Si Parat 1, Si Aul Ujung and si Cayur. Si Kembar and Si Patahunan caver are not suitable to be developed

Judul: Fraksinasi Metil Ester Olein Menggunakan Fractional Distillation System untuk Menghasilkan Metil Ester Palmitat (C16 )
Abstrak: Palm olein biodiesel is consist of fatty acid methyl ester mixture. Separation of methyl ester fraction can be performed by fractionation technique. Fractional distillation system is used in this research to separate the dominant of methyl ester palmitic (C16). Fractional distillation system composed of several main components i.e boiling vessel, column with packing, condenser, vacuum unit, water cooling unit, heating unit and reciever vessel. This study was conducted using completely randomized factorial design. Fractionation process is done by using two experimental factors i.e temperature process (225 oC, 230 oC, 235oC) and processing time (10 and 12 hours). Separation process produces two fraction of biodiesel, distillate and residual biodiesel. The best condition to separate dominant of methyl ester palmitic faction obtained at the experimental unit temperature 235oC and processing time of 12 hours. The purity of C16 methyl ester fraction is 80,17% (w/v). Residual biodiesel can be obtained as dominant of methyl ester oleic (C18:1) is 60,80% (w/v) in experimental unit 235oC and 10 hours.Distillate biodiesel has several changes in physicochemical properties such as decreasing of density value, decreasing of iodine value, decreasing of saponification value, decreasing of acid number and levels of FFA compared to the initial biodiesel. Physicochemical changes in distillate caused by the composition of FAME biodiesel that is dominated by saturated methyl esters and lower molecular weight. Meanwhile, residual biodiesel is physicochemically changes by increasing density value, increasing of iodine value, increasing of saponification value, increasing of acid value and levels of FFA. This changing is caused by unsaturated methyl ester, higher molecular weight and also higher content of free fatty acids which are formed due to high temprature during the process
