Abstrak: Organic farming is one of the alternative solutions for environmental damage due to the use of synthetic materials input. Therefore, the objective of the study is to describe ricefield farmers attitude, to analyze attitudinal differences between non, semi, and organik ricefield farmers, to analyze the influencing factors on ricefield farmers attitude toward the implementation of organic farming. The study was conducted by survey methods on April 2013 in Magelang Subregency. 105 respondets was selected through sensus sampling and snowball sampling technique. The results shows that the ricefield farmers in Magelang Subregency are tends to have positive attitude towards the implementation of organic farming.

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.
