Abstract

Herpetofauna communities are formed due to the suitability of the habitat or adaptation process that forces a species to survive. The opening of the land mines result in missing or changing the habitat of herpetofauna. This research was conducted to know the preferences of the herpetofauna of habitat based on spatial distribution of herpetofauna in the vicinity of mining area of PT Singlurus Pratama. The survey was conducted in the area of revegetasi, forest fragmentation, the district adjacent to the mining area, rivers and water spots or natural and man-made on two mining blocks i.e. block Pearl and block independence. The method of election of purposive sampling location with direct search survey methods (Visual Encounter Surveys). The main species found 4 that its spread most widely with populations high. The most frequent species of herpetofauna and many found among others: Eutropis multifasciata, Enhydris enhydris, Fejervarya cancrivora, Polypedates leucomystax and Duttaphrynus melanostictus. Based on the value of the index indicates that the diversity of herpetofauna communities distress with low. Types of herpetofauna more land cover found in the undergrowth, secondary forest and agricultural areas that there are sources of water in it.

Abstract

This research was carried out in Kumpai Batu Atas Village, South Arut District, Kotawaringin Barat Regency. This study aims to determine the influence of the role of agricultural extension agents on the socio-economic conditions of farmers. Data analysis method uses Likert scale, descriptive analysis, multiple linear regression analysis, f-test and determination coefficient. The data collected in this study are primary data and secondary data.The socio-economic conditions of farmers in "ngawi" farmer groups consist of the age of farmers 30-40 years (12%), 41-50 years (24%), 51-60 years (48%); education consists of elementary school (64%), junior high school (32%), S1 (4%); income level range <Rp. 1,500,000 (34%), Rp. 1,500,000 - Rp. 2,500,000 (64%),> Rp. 2,500,000 - Rp. 3,000,000 (12%) and the work of the farmer respondent all (100%) earns a living as farmer.                 The results showed the hypothesis testing together had a fcount of 0.087 smaller than the value of ftabel of 3.44 which means that Ha was rejected and H0 was accepted, this indicates that the independent variable includes the factors of instructor as educator, facilitator and supervisor together- the same does not affect the dependent variable, namely the socio-economic conditions of the farmers. Based on the results of multiple linear regression analysis obtained equation Y = 1.64 + 0.35 X1 + 0.13 X2 + 0.05 X3 + e which indicates a positive influence between the instructor factors as educators, facilitators and supervisors on the social economic conditions of farmers. The coefficient of determination (R2) obtained shows that 11.1% of socioeconomic conditions can be influenced by the extension factor as an educator, facilitator and supervisor.

Abstract

Penilaian Efektivitas Pengelolaan Kawasan Konservasi di Kawasan Cagar Alam Padang Luway Kabupaten Kutai Barat.  Kawasan Konservasi memiliki fungsi yang sangat penting yaitu sebagai sebuah sistem penyangga kehidupan. Meski demikian, karakteristik biologis dan kepentingan pengelolaannya yang kompleks menyebabkan selama ini kawasan konservasi belum dikelola secara efektif sehingga mengalami kerusakan secara terus menerus. Hal tersebut mendorong dilakukannya penelitian ini yang bertujuan untuk mengkaji efektivitas pengelolaan Kawasan Konservasi Cagar Alam Padang Luway berdasarkan nilai penting pada setiap siklus pengelolaan yaitu perencanaan, masukan, proses, dan keluaran dan mengetahui nilai komponen yang kurang pada setiap siklus pengelolaan yang mempengaruhi efektivitas pengelolaan kawasan Cagar Alam Padang Luway.Penelitian dilakukan pada kawasan Cagar Alam Padang Luway dengan menggunakan pendekatan Rapid Assessment and Prioritization of Protected Area Management (RAPPAM). Sebagai kawasan suaka alam, Cagar Alam Padang Luway merupakan kawasan yang memiliki fungsi sebagai lokasi penelitian dan pengembangan ilmu pengetahuan. Kondisi dan realitas objektif kawasan Cagar Alam Padang Luway menuntut upaya pengelolaan yang lebih terarah dan berkesinambungan serta lebih mendayagunakan potensi sumberdaya alam yang ada untuk kepentingan pendidikan dan kelestarian ekologis kawasan tersebut sehingga untuk mengetahui efektivitas pengelolaan Cagar Alam Padang Luway perlu dilakukan penilaian dengan menggunakan metode RAPPAM. Hasil penelitian dengan menggunakan metode RAPPAM menunjukkan bahwa kawasan Cagar Alam Padang Luway memiliki nilai biologis maupun ekonomis tinggi tetapi kawasan ini belum dikelola secara efektif. Strategi yang dihasilkan RAPPAM lebih sesuai untuk kebijakan nasional, Untuk dapat diaplikasikan di tingkat kawasan konservasi masih dibutuhkan analisis lanjutan berdasarkan kondisi masing-masing kawasan sehingga diperoleh suatu strategi yang menjawab kebutuhan lokal kawasan tapi tetap dalam kerangka kebijakan nasional.Pengelolaan Cagar Alam Padang Luway mempunyai potensi alam yang besar untuk penelitian dan pengembangan ilmu pengetahuan, pendidikan dan konservasi alam, penyerapan dan penyimpanan karbon, serta pemanfaatan sumber plasma nutfah untuk penunjang budidaya,  akan tetapi belum termanfaatkan secara optimal.  Kegiatan prioritas tersebut adalah memberikan kesempatan kepada semua pihak (stakeholders) di dalam menjaga keberadaan Cagar Alam Padang Luway untuk kepentingan semua pihak serta meningkatkan keterpaduan pengelolaan dengan kerjasama kemitraan dan peningkatan kesadaran masyarakat untuk berperan aktif dalam upaya konservasi sumber daya alam.
