Judul: Respon Pelaku Usaha Hutan Rakyat Terhadap Kebijakan Surat Keterangan Asal Usul Kayu (Studi Kasus di Desa Jugalajaya, Kecamatan Jasinga, Kabupaten Bogor).
Abstrak: Penelitian ini dilaksanakan di Desa Jugalajaya, Kecamatan Jasinga, Kabupaten Bogor pada Bulan Mei – Juni 2011. Metode yang digunakan dalam penelitian ini adalah metode kualitatif yang bersifat deskriptif. Data yang dikumpulkan berupa data primer yang terdiri dari data responden, proses adopsi implementasi kebijakan SKAU, respon masyarakat atau petani serta stakeholders terkait terhadap implementasi kebijakan SKAU, dan permasalahan dalam pelaksanaan SKAU. Data sekunder yang dikumpulkan adalah kondisi umum fisik daerah penelitian dan potensi hutan rakyat. Penilaian proses adopsi menggunakan teori Rogers dan Shoemaker (1971) yang menyebutkan bahwa proses-proses adopsi terdiri dari 5 tahap, yaitu : tahap sadar, tahap minat, tahap evaluasi, tahap percobaan, dan tahap adopsi. Sedangkan penilaian respon mengunakan teori Sajogyo dan Pudjiwati (2002) yang menyebutkan bahwa respon terbagi menjadi 3 macam yaitu : respon positif, respon negatif, dan respon netral. Respon yang ditunjukkan oleh petani terhadap SKAU adalah negatif, karena dari kelima tahapan adopsi, hanya tahap sadar, tahap minat, dan tahap evaluasi saja yang dilakukan oleh petani, sedangkan tahap percobaan dan tahap adopsi tidak dilakukan karena sistem penjualan kayu melalui tengkulak. Respon tengkulak/pengusaha kayu dan Pejabat Desa terhadap SKAU adalah netral, karena kelima tahapan adopsi dilaksanakan tetapi tidak sesuai dengan isi Peraturan tentang SKAU. Sedangkan Respon Pejabat Dinas Kehutanan terhadap SKAU adalah positif, karena kelima tahapan adopsi dilaksanakan dan sesuai dengan isi Peraturan tentang SKAU. Kendala yang dihadapi dalam pelaksanaan SKAU diantaranya : dokumen SKAU yang digunakan, sistem penjualan kayu di hutan rakyat, jenis kayu yang diangkut, serta kurangnya sosialisasi dan pengawasan dari Pejabat Dinas Kehutanan

Abstrak: In framework to support the movement of forestry sector with economic support of people are needed the recognition, protection and the orderly distribution of forest products from smallholder private forest by the Ministry of Forestry concerning the People's Wood Administration issued through the document of The Origin Certificate of Wood (SKAU). SKAU published by the Village Head or an equivalent officer of the Village Head in areas where the timber will be transported and aims to facilitate the public in transporting the forest products. This refers to the Minister of Forestry Regulation No. P.51/Menhut-II/2006, Number P.62/Menhut-II/2006 and Number P.33/Menhut-II/2007.The research was conducted in Jugalajaya Village, Jasinga District, Bogor Regency on May-June 2011. The method that used in this study is descriptive-qualitative. Data that was collected is primary data that consists of respondent data, the adoption process of SKAU policy implementation, public or peasants response and relevant stakeholders on the SKAU implementation policies, and problems in SKAU implementation. Secondary data that collected were general physical condition of research areas and the potential of smallholder private forest. The assessment of adoption process uses the theory of Rogers and Shoemaker (1971) which states that the adoption process consists of five stages: awareness stage, interest stage, evaluation stage, trial stage, and adoption stage. While the assessment of response uses the theory of Sajogyo and Pudjiwati (2002) which states that the response is divided into three kinds: positive response, negative response, and neutral response. The response shown by farmers on SKAU is negative, because from the five stages of adoption, only the awareness stage, interest stage, and evaluation stage was performed by farmers, while the trial stage and adoption stage not performed because the system of timber sales is through middlemen. The responses of middlemen/wood businesses and village officials to SKAU is neutral, because the five stages of adoption executed but not in accordance with the contents SKAU regulations. While the response of the forest department officials on SKAU were positive, because the five stages of adoption performed. Constraints faced in the implementation of SKAU: the SKAU documents itself, the wood sales system on smallholder private forest, the species of wood that being transported, and lack of socialization and supervision by the forest service officials.

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
