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: Maraknya eksploitasi kawasan karst untuk penambangan mengakibatkan banyaknya kerusakan di kawasan karst. Padahal, karst memiliki nilai-nilai penting bagi kehidupan, diantaranya nilai ekologis, ilmiah, ekonomis, sosial dan budaya. Salah satu upaya konservasi kawasan karst yang dapat memberikan keuntungan baik bagi kawasan maupun masyarakat adalah dengan pengembangan kegiatan wisata. Salah satu bentuk wisata yang bisa dikembangkan dapat berupa wisata minat khusus. Penelitian ini dilakukan di kawasan Karst Gudawang, Kampung Cipining, Desa Argapura, Kecamatan Cigudeg, Kabupaten Bogor selama 3 bulan (Desember 2006 - Februari 2007). Metode yang digunakan adalah metode forward untuk pemetaan gua, sedangkan untuk data potensi wisata menggunakan metode wawancara dan observasi. Gua Gudawang merupakan salah satu kawasan karst yang dikembangkan sebagai obyek wisata yang mengutamakan gua sebagai obyek utama. Kawasan karst Gudawang terdiri dari 24 gua terbagi atas gua kering dan berair. Sebanyak 2 dari15 gua yang berair, 2 telah dikembangkan untuk wisata masal, 8 gua dapat dikembangkan sebagai wisata minat khusus, 2 gua tidak dapat dilakukan kajian dan 3 gua lainnya tidak dapat ditemukan.

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
