Judul: Faktor-Faktor yang Mempengaruhi Sikap Petani Padi Sawah terhadap Penerapan Pertanian Organik
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. Also, there is attitudinal differences among farmers. Non formal education, farming ecperience, capital ownership, acces to agricultural input material, and the values of the group has effect on the ricefield farmers attitude.

Judul: Income Analysis and Factors Affecting Willingnes to Adopt for SRI Organic Method in Rice Farming (Case Study: Bumi Harapan Village, Wita Ponda Subdistrict, Morowali District, Provinsi Sulawesi Tengah)
Abstrak: Analisis Pendapatan dan Faktor-Faktor yang Memengaruhi Willingnes to Adopt Metode SRI Organik Pada Usahatani Padi (Studi Kasus : Desa Bumi Harapan, Kecamatan Wita Ponda, Kabupaten Morowali, Provinsi Sulawesi Tengah). Dibimbing oleh HASTUTI dan DEA AMANDA. Indonesia mencapai swasembada beras nasional tahun 1984 dengan sistem pertanian konvensional, prestasi tersebut tidak berkelanjutan karena dihadapkan berbagai masalah. Menyikapi permasalahan tersebut, inovasi pertanian padi organik dapat diterapkan. Pertanian Organik berbasis kearifan lokal diperkenalkan untuk pengembangan pertanian organik adalah System of Rice Intensification (SRI) Organik. Tujuan penelitian (1) menganalisis persepsi petani terhadap penggunaan metode SRI Organik, (2) menganalisis perbandingan pendapatan padi Organik dan padi konvensional, (3) menganalisis faktor yang memengaruhi kesediaan adopsi metode SRI Organik. Penelitian ini menggunakan analisis skala Likert untuk mengetahui persepsi petani, analisis pendapatan untuk mengetahui perbandingan pendapatan, dan analisis regresi logistik untuk mengetahui faktor yang memengaruhi kesediaan adopsi. Hasil persepsi penggunaan metode SRI Organik pada petani yang mengadopsi metode SRI Organik yang tertinggi yaitu produksi padi SRI Organik yang lebih tinggi dan sehat, persepsi terendah teknis budidaya SRI organik yang rumit. Persepsi terhadap penggunaan metode SRI Organik pada petani yang belum mengadopsi metode SRI Organik tertinggi yaitu SRI Organik menggunakan pupuk dan pestisida ramah lingkungan, persepsi terendah yaitu ketersediaan tenaga kerja pertanian produktif dan terampil terbatas. Analisis pendapatan menunjukan R/C ratio lebih dari satu artinya usahatani menguntungkan. Faktor yang signifikan memengaruhi petani mengadopsi padi metode SRI Organik yaitu pengalaman, pernah mendapat pelatihan dan status kepemilikan lahan. Kata kunci: pertanian konvensional, regresi logistik, skala likert, usahatani padi, Income Analysis and Factors Affecting Willingnes to Adopt for SRI Organic Method in Rice Farming. (Case Study: Bumi Harapan Village, Wita Ponda Subdistrict, Morowali District, Provinsi Sulawesi Tengah). Supervized by HASTUTI and DEA AMANDA. Indonesia achieving national rice self-sufficiency in 1984 with a conventional farming system, this achievement is not sustainable because it is faced with various problems. In response to these problems, organic rice farming innovations can be applied. Organic agriculture based on local wisdom introduced for the development of organic agriculture is the Organic System of Rice Intensification (SRI). The objectives of the study (1) were to analyze farmers' perceptions of the use of the Organic SRI method, (2) to analyze the income comparison between Organic and conventional rice, (3) to analyze the factors that influenced the willingness to adopt the Organic SRI method. This study uses a Likert scale analysis to determine farmer perceptions, income analysis to determine income comparisons, and logistic regression analysis to determine factors that influence adoption willingness. The results of the perception of the use of the Organic SRI method on farmers who adopt the Organic SRI method are the highest, namely the production of organic SRI rice which is higher and healthier, the lowest perception of complicated organic SRI cultivation techniques. The highest perception of the use of the Organic SRI method in farmers who have not adopted the Organic SRI method is Organic SRI using environmentally friendly fertilizers and pesticides, the lowest perception is that the availability of productive and skilled agricultural labor is limited. Income analysis shows that the R/C ratio is more than one, meaning that

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.
