Judul: Identifikasi kebutuhan kayu bakar menurut asal pada industri gula kelapa di Kecamatan Wangon Kabupaten Banyumas Jawa Tengah
Abstrak: Kabupaten Banyumas merupakan sentra industri penghasil gula kelapa. Salah satu daerah yang menghasilkan produk gula kelapa terbesar yaitu Kecamatan Wangon. Permintaan gula kelapa sebagai bahan baku dalam konsumsi rumah tangga dan industri makanan semakin meningkat mengakibatkan kebutuhan kayu bakar juga meningkat. Penelitian ini bertujuan untuk mengidentifikasi sumber kayu bakar yang digunakan, mengidentifikasi teknik memperoleh kayu bakar, menghitung kebutuhan kayu bakar yang digunakan dalam industri gula kelapa, dan menghitung potensi kayu bakar di Kecamatan Wangon. Penelitian ini dilakukan dengan pengamatan langsung ke industri gula kelapa. Data yang diperoleh dianalisis dengan metode deskriptif. Hasil penelitian ini menunjukan bahwa bahan bakar utama dalam mengolah gula kelapa berasal dari hutan rakyat dan tambahannya berasal dari hutan negara. Berdasarkan asal geografis kayu bakar diperoleh dari dalam desa dalam kecamatan sebanyak 92%, luar desa dalam kecamatan sebanyak 6% dan dari luar desa luar kecamatan sebanyak 2%. Industri yang memperoleh kayu bakar dengan cara memungut dan memangkas sebanyak 64 % dan yang memperoleh dengan cara membeli sebanyak 36%. Potensi kayu bakar yang tersedia di Kecamatan Wangon sebanyak 180.195,05 m3. Kebutuhan kayu bakar untuk industri gula kelapa di Kecamatan Wangon sebanyak 10.888,03 m3/tahun. Penelitian ini menunjukan bahwa potensi kayu bakar mampu memenuhi kebutuhan kayu bakar selama 16,55 tahun dengan jumlah tegakan tidak mengalami perubahan.

Judul: Identifikasi Kebutuhan Kayu Bakar Menurut Asal pada Industri Gula Kelapa di Kecamatan Wangon Kabupaten Banyumas Jawa Tengah
Abstrak: Banyumas District is a central industry of coconut palm sugar. One region that produces the most coconut palm sugar product is Wangon Sub-District. The demand of coconut palm sugar as raw materials on the household consumption and food industry is increasing which also effects the needs of firewood. This research aims to identify the source of firewood that is used, to identify the technique to obtain firewood, to calculate the needs of firewoods that is used in the coconut palm sugar industry, and to calculate the firewood potential at Wangon Sub-District. This research was done by direct observation to the coconut palm sugar producers and the collected data was analyzed by descriptive method. The result of this research shows that the main fuel on the processing of coconut palm sugar was obtained from the society forest and the addition was obtained from the states forest. Based on the geographic origin, firewoods which were obtained from inside the village and inside the sub-district is as much as 92%, firewood obtained from outside the village and inside the sub-district is as much as 6% and firewood obtained from outside the village and outside the sub-district is as much as 2%. Producers which obtained firewoods by collecting and trimming is as much as 64%, while firewoods obtained by buying is as much as 36%. Firewood potential which is available at Wangon Sub-District is 180.195,05 m3. The needs of firewood for coconut palm sugar industry at Wangon Sub-District is 10.888,03 m3/year. This research shows that the firewood potential can fulfill the needs of firewood for 16.55 years with unchanged number of stands.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
