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 Jalur Interpretasi di Kawasan Wisata Gunung Padang, Sumatera Barat.
Abstrak: Gunung Padang merupakan salah satu kawasan wisata alam di Kota Padang, Sumatera Barat. Potensi Gunung Padang dapat digunakan sebagai penyampai informasi tentang kelestarian kawasan kepada pengunjung melalui kegiatan interpretasi. Beberapa potensi yang keberadaannya belum disadari dapat diinterpretasikan dengan jalur interpretasi yang didukung dengan perencanaan lanskap jalur interpretasi. Penelitian ini bertujuan untuk menyusun perencanaan jalur melalui potensi kawasan dan preferensi pengunjung. Data yang dikumpulkan meliputi potensi objek, preferensi pengunjung dan identifikasi jalur eksisting, dengan metode wawancara, studi pustaka dan pengamatan lapang. Data kemudian dianalisis dan dinilai dengan penilaian jalur dan objek sebagai dasar perencanaan intepretasi. Gunung Padang memiliki 20 jenis flora, empat jenis mamalia, sembilan jenis burung, lima jenis aspek sejarah budaya dan tiga daya tarik fisik yang terdapat pada tiga jalur eksisting. Objek yang paling disenangi responden yaitu panorama alamnya dan materi interpretasi yang diinginkan yaitu mengenai sejarah atau kondisi Gunung Padang. Konsep dasar perencanaan jalur kemudian dikembangkan menjadi konsep tata ruang, sirkulasi dan konsep aktivitas fasilitas.

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.
