Judul: Perencanaan Lanskap Rekreasi “Area Outbound” Kawasan Taman Hutan Raya Ir. H. Djuanda, Bandung
Abstrak: Ir. H. Djuanda grand forest park is one type of conservation toward regional management of germplasm scope. The purpose of this study is to identify the physical, social and tourism potential of the region as well as recreation on the landscape plan. The research methodology is consisted of 5 stages that are preparation, inventory, analitycal, syntetical, and over planning. There are spatial and descriptive analysis in the analytical stage. However the data analysis was done by looking at biophysics condition, touring aspect condition along with social aspect. According to the result of analysis, it is needed an effort to enrich an advanced area through increasing the facility and repair the facility that out order beside to set up a better place for many people to come for recreation. Based on spatial analysis, it has been gotten some zones like terrain map for landscape planning. Scenery over planning is aimed to support the existence of all Ir.H.Djuanda grand forest park objec

Judul: Analisis ketersediaan sumber daya untuk pengembangan rekreasi Taman Hutan Raya IR. H. Djuanda Bandung
Abstrak: Penelitian ini dilakukan di Taman Hutan Raya Ir H. Djuanda Bandung yang terletak ± 7 km sebelah utara Kota Bandung, Jawa Barat. Penelitian bertujuan mengetahui ketersediaan sumber daya untuk pengembangan rekreasi yang ada di dalam maupun di luar kawasan THR Djuanda. Penelitian ini merupakan penerapan Ukuran Baku Penilaian dan Pengembangan Obyek Rekreasi Alam (PHPΑ, 1983) untuk penilaian dan pengembangan obyek rekreasi dengan metode survai. Kriteria penelitian lebih ditekankan kepada aspek potensi kawasan yang terdiri dari daya tarik, pengelolaan perawatan. pelayanan, kondisi iklim, ketersediaan air (potensi dalam kawasan). Potensi pasar, kadar hu- bungan, prasarana dan sarana penunjang, kondisi lingkungan, akomodasi dan ubungan dengan obyek rekreasi lain merupakan potensi di luar kawasan. Ketersediaan sumber daya untuk pengembangan rekreasi dinilai berdasarkan analisis dari 10 potensi tersebut. Data diperoleh dengan wawancara, pengamatan lapang, studi pustaka. Sehubungan dengan adanya penilaian yang kualitatif, penilaian ketersediaan sumber daya dilakukan oleh 5 orang dan hasilnya dirata-ratakan.

Judul: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
