Judul: Perencanaan Jalur Interpretasi Kawasan Hutan Pendidikan Gunung Walat Sukabumi, Jawa Barat
Abstrak: Gunung Walat Education Forest (GWEF) is a forest area which have potential objects and trails can be developed as interpretation trail. The aims were to identify potential interpretation objects and condition at eight trails in GWEF, to identify visitor’s preferences, and planned the landscape interpretation trail of GWEF. Data analyzed using the criteria tool analysis developed by Veverka (1998), scoring, and descriptive. The result is that on eight trails consist of 24 plant objects, 19 animal objects, five physical objects, a historical and ancient site object. Plant object become main visitor’s preference amount 40%. There ware eight interpretation trail which consist of three classification are as follow high potential (two trails), medium potential (one trail), low potential (five trails).

Judul: Perencanaan Program Interpretasi Hutan Pendidikan Gunung Walat Sukabumi Jawa Barat
Abstrak: Hutan Pendidikan Gunung Walat (HPGW) merupakan kawasan hutan dengan tujuan khusus sebagai sarana pendidikan bagi masyarakat dan pengunjung. Program interpretasi merupakan salah satu cara terbaik dalam membantu pengunjung memahami informasi yang diberikan kerana memberikan pengalaman langsung kepada pengunjung. Penelitian ini bertujuan untuk menyusun program interpretasi di HPGW agar bisa digunakan secara berkelanjutan. Analisis data dilakukan secara tabulasi dan deskriptif. Obyek interpretasi yang bisa diangkat menjadi obyek utama interpretasi adalah potensi biologi (flora dan fauna) dan fisik (Gua Putih). Sebagian besar pengunjung memilih flora dan fauna (87%) sebagai materi yang paling diinginkan dalam program interpretasi dengan aktivitas yang dilakukan yaitu perjalanan dan pengamatan langsung. Program interpretasi yang disusun bertema “Jelajah Hutan HPGW, Ungkap Pesona Flora dan Faunanya”dengan target sasaran merupakan pengunjung dengan kelompok umur remaja dan dewasa. Teknik interpretasi yang digunakan yaitu teknik interpretasi langsung dengan metode panduan personal dan swa-panduan.

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.
