ABSTRAK Penelitian ini mengevaluasi program konversi minyak tanah ke Liquefied Petroleum Gas (LPG) pada kelompok sasaran di pulau Gili Raja kabupaten Sumenep Jawa Timur. Kajian sebelumnya terhadap program ini masih bersifat formatif dengan fokus efisiensi dan efektivitas implementasi. Dengan menggunakan metode Minimum Evaluation Procedure (MEP) penelitian ini mempertanyakan implementasi program secara runtut, mulai output, outcome sampai impact. Melalui pendekatan kualitatif penelitian ini dapat mendeskripsikan konteks dan setting secara alamiah. Hasil penelitian menunjukkan adanya pungutan dalam proses distribusi paket program, rendahnya akses atau penggunaan paket program serta tidak adanya dampak program. Selain itu, ditemukan adanya potensi lokal berupa kotoran ternak yang dapat dikembangkan menjadi sumber daya energi terbarukan. Berdasarkan hal itu, disarankan sebuah program dapat dikembangkan secara asimetris sesuai dengan kondisi lokasi dan kelompok sasaran, terjadinya komunikasi intensif antara pelaksana program dengan kelompok sasaran serta stakeholders lainnya. Berdasarkan potensi kelompok sasaran di pulau Gili Raja, hendaknya dikembangkan kebijakan energi alternatif biogas untuk memenuhi kebutuhan energi masyarakat serta mendukung pencapaian tujuan kebijakan energi nasional. ABSTRACT The purpose of this research is to evaluate the conversion programfrom kerosene to Liquefied Petroleum Gas (LPG) on a target group in Gili Raja island of SumenepMunicipal, East Java. Previous study on this program was quite formative one and focusing on the efficiency and the effectiveness of the program implementation. In addition, by applying Minimum Evaluation Procedure’s (MEP) method, this research questioned the implementation of the program consecutively from the output, the outcome as well as the impact. Furthermore, through a qualitative approach, this research will be able to describe context and setting naturally. Result of the research shows that there is illegal fees (levies) in the process of distributing the program package, also the limited access or the low utilization of the program package, as well as the non-existing evidence of the program’s impact. Furthermore, it is found a local potential in the form of renewable energy that is generated from livestock’s feces. Hence, it is recommended to establish a program, asymmetrically, in accordance with the local condition and the target group that ensures the occurrence of an intensive communication amongst program implementer, target group, and other stakeholders. Moreover, based on the potency of the target group of Gili Raja, an alternative policy on renewable energy should be developed in order to fulfill the need of energy for Gili Raja’s people, as well as to support the achievement of the National energy policy.

ABSTRAK Penelitian ini bertujuan untuk mengkaji komunitas rayap akibat alih guna hutan dan hubungannya dengan faktor lingkungan. Penelitian dilaksanakan dari bulan Desember 2011 sampai Juni 2013. Dilaksanakan di wilayah Taman Nasional Lore Lindu di sekitar Desa Rahmat, Kecamatan Palolo, Kabupaten Sigi. Pengamatan rayap dilakukan dengan menggunakan metode transek. Parameter yang diamati adalah parameter lingkungan, iklim mikro, sifat fisik dan kimia tanah. Total diversitas rayap yang ditemukan adalah 20 spesies, yang terdiri dari 15 spesies pada hutan primer, 15 spesies pada hutan sekunder dan 8 spesies pada agroforestri. Biomassa pohon tertinggi pada hutan primer (620,91 Mg/ha), nekromas dan jumlah seresah tertinggi pada hutan sekunder yaitu masing-masing 8,22 Mg/ha dan 19 Mg/ha. Hasil penelitian ini membuktikan bahwa alih guna hutan menjadi agroforestri diikuti oleh perubahan komunitas rayap. Suhu tanah dan suhu udara meningkat setelah alih guna hutan. ABSTRACT This study was conducted to evaluate the termines community impact forest conversion and its relation with the environmental factors. It was conducted from December 2011 to June 2013 and implemented in Lore Lindu National Park located in around of Rahmat village, subdistrict of Palolo, district of Sigi.

ABSTRAK Biaya produksi biodiesel menjadi salah satu hambatan program konversi bahan bakar minyak ke biodiesel negara-negara termasuk Indonesia dalam upaya mengantipasi terjadinya krisis energi. Salah satu penyebab biaya produksi yang tinggi adalah karena variabel biaya produksi yang diperbandingkan selama ini belum sepenuhnya mencerminkan keseluruhan potensi yang terkandung dalam biodiesel. Potensi biodiesel yang tergolong ke dalam komoditas lingkungan seperti sifat terbarukan, rendah dalam penggunaan lahan, dan ramah lingkungan perlu dimasukkan dalam perhitungan agar mendapatkan perbandingan perhitungan yang obyektif. Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan komoditas lingkungan pada stuktur biaya produksi biodiesel dari minyak sawit dan minyak alga. Nilai komoditas lingkungan diperkirakan dengan metode metode benefit transfer dan untuk memperlihatkan nilai keuntungan digunakan pendekatan willing to pay (WTP). Nilai-nilai komoditas lingkungan diacu dari hasil perhitungan perangkat lunak Environmental Priority Strategy (EPS) versi 2000. Untuk kasus Indonesia, nilai komoditas lingkungan EPS diinferensi dengan elastisitas berdasarkan dari perbandingan nilai pendapatan per kapita negara Swedia dan Indonesia. Hasil penelitian menyatakan bahwa analisis life cycle costing (LCC) yang diaplikasikan dengan menambahkan variabel eksternalitas dapat memberikan informasi yang detil tentang komposisi biaya produksi biodiesel dan dapat digunakan sebagai metode untuk mendapatkan gambaran total biaya produksi yang paling kompetitif dari beberapa sumber. Analisis juga menyimpulkan bahwa variabel eksternalitas turut mempengaruhi kenaikan total biaya produksi biodiesel hingga 14%. Hasil analisis profitabilitas menyatakan bahwa pasokan biomasa alga untuk produksi biodiesel lebih terjamin dan berkelanjutan dibandingkan biomasa sawit karena kendala teknis dan non teknis pada produksi biomasa alga lebih mudah diatasi selain itu juga keunggulan perannya dalam mitigasi GRK yang turut memperbesar peluang sebagai bahan utama biodiesel di masa depan. ABSTRACT The high cost of biodiesel production was to be an obstacle conversion to biodiesel fuel including Indonesia due to anticipate the energy crisis. The high cost of production due to the variable cost of production has not fully comparable reflect the overall potential contained in biodiesel. Potential biodiesel belonging to the commodity nature of the environment such as renewable biomass, low in land use, and environmentally friendly should be included in the calculation in order to obtain an objective comparison of the calculations.This study aimed to evaluate the effect of adding commodities to the structure of the production cost of biodiesel between palm oil and algal oil. Estimated value of the commodity by the method of benefit transfer method shows the value used is the approach gains willingness to pay (WTP). Environmental commodity values referenced from the calculation software Environmental Priority Strategy (EPS) version 2000. For the case of Indonesia, the commodity value of the elasticity was infered EPS basis of comparison of income per capita of Sweden and Indonesia.The results stated that the analysis of life cycle costing (LCC) applied by adding variable externalities can provide detailed information about the composition of biodiesel production costs and can be used as a method to get a total picture of the most competitive production costs from several sources. The analysis also concluded that the externality variables also affect the total cost of biodiesel production by up to 14%. Profitability analysis stated that the algal biomass for biodiesel production more secure and sustainable than palm biomass due to technical and non-technical constraints on the production of algal biomass more easier to treat but it also advantages role in GHG mitigation that helped widen the opportunities as the main ingredient of biodiesel in the futur
