Judul: Peran Pengelolaan Hutan Bersama Masyarakat dalam Mengatasi Masalah Pencurian Kayu Studi Kasus di KPH Jember Perum Perhutani Unit II Jawa Timur
Abstrak: Forest could simply be defined as a unified ecosystem in which the biological resources are dominated by trees that are tightly bound each other, in terms of environmental balances. Due to the various potential applications of any forestry resources, make forest prone to any missed-law exploitations (e.g., illegal logging). As a consequence, to negate the number of illegal logging, Perum Perhutani has initiated a program_Forest Management based of Community (PHBM). Hence, this study was aimed to evaluate the effectiveness of PHBM as an effort to cut-down illegal logging especially in the boundary of KPH Jember Perum Perhutani Unit II East Java. This research was conducted by employing such stratification-of-random-sampling method, with group classifications of monthly income and occupation. Additionally, selection of the villages was according to the purposive–sampling method. There were two distinguishable data utilized such as: (i) primary data (field studies and interview of 90 respondents) and (ii) secondary data (information found in books, scientific journals, thesis, dissertation and other documentary resources). The data showed several concluding remarks of illegal logging characteristics, such as (a) types of wood being stolen, likely sengon, teak and mahogany, (b) diameter of the tree of approximately 10-30 cm, (c) reason for selecting such diameter as it is easy to transport, and (d) the illegal logging becomes a major alternative way for the local people to fit out them necessaries. Furthermore, the number of the illegal logging in 2008-2012 decreased from 229 to 118 cases, except for the RPH Mumbulsari which was still increased. The main role of local people for tackling illegal logging located in RPH Mumbulsari, RPH Garahan and RPH Jelbuk was done by patrol activities including making such control-posts in certain locations. However, the data showed the effectiveness of PHBM program on the RPH Mumbulsari wherein a pattern of mixed-planting between teak and crops (palawija) implemented could not reduce the number of illegal logging significantly, whereas one that a pattern of mixed planting between pine and crops or coffee (RPH Garahan and RPH Jelbuk) carried out showed the positive impacts by the reduced number of illegal logging.

Judul: Partisipasi Masyarakat Desa Hutan dalam Program Pengelolaan Hutan Bersama Masyarakat di KPH Cepu Perum Perhutani Unit I Jawa Tengah
Abstrak: Since a long time ago, the people of Indonesia in satisfying such needs as houses, clothing, food, medicine, and environmental services have depended heavily on forests. The increase of population has caused the living necessities to increase and triggered the exploitation of forest resources commercially at a large-scale. Based on the recapitulation of KPH Cepu, the incidence of theft and forest fires is high every year. Responding to the increasing forest disturbances, Perhutani applied several new multi-sector policies related to forest management. One form of the new policies is the PHBM (Forest Management together with Community) program. KPH Cepu began to launch the program in 2003. This program opens an opportunity for people to participate directly in forest management. This started with the establishment of cooperation between Perhutani and LMDH (Rural Forest Community Institution). One element of the successful implementation of PHBM is the effectiveness of LMDH. An effective LMDH is one that involve the community in each activity. The study was conducted in the villages of Bleboh and Nglebur, Perum Perhutani KPH Cepu Unit I Central Java, from September 2011 through November 2011. The data used were of primary and secondary types. The purpose of this study was to identify the activities of PHBM, analyze people‟s participation in the PHBM program, and analyze the effectiveness of LMDH. the number of selected villages was two, namely the village of Bleboh and Nglebur with 30 respondents in each village. Based on the research results, there are two types of activities in PHBM at KPH Cepu: the activities inside the forest area and the activities outside the forest area. The inside activities include planting, maintaining, intercropping, and security. The outside activities involve the establishment of saprotan shop, cattle and goats breeding, empon-empon farming, and nurseries. The implemented program of PHBM in LMDH of Wana Sumber Mulyo consists of the activities only inside forest area, whereas the PHBM program in LMDH of Wana Tani Makmur includes the activities both inside and outside the forest area. Participation of pesanggem in PHBM program is still partial, i.e. limited to the phase of implementation and allocation of shared profit from non-wood products. The effectiveness LMDH as an institution has not yet complied with the four principles of good forest governance.

Judul: Desain Sistem Transfer Energi Nirkabel Berbasiskan Tesla Coil
Abstrak: Tesla coil merupakan alat yang ditemukan oleh Nikola Tesla yang dapat mentransmisikan daya tanpa kabel dengan memanfaatkan prinsip induksi elektromagnetik. Pada penelitian ini dibuat sebuah prototype Tesla Coil dengan menggunakan transistor C1970 dan receiver menggunakan rangkaian LC. Identifikasi alat meliputi pengaruh daya input transmitter terhadap receiver, bentuk signal yang dipancarkan transmitter, pengaruh jarak transmitter dan receiver, nilai efisiensi serta efek alat terhadap perangkat lain. Hasil pengamatan menunjukkan bahwa semakin besar daya input maka semakin besar daya yang dipancarkan oleh transmitter. Bentuk sinyal yang dipancarkan oleh transmitter berupa gelombang listrik AC sinusoidal dengan frekuensi ~2.9 MHz. Semakin jauh jarak receiver terhadap transmitter maka semakin kecil amplitudo gelombang AC yang diterima oleh receiver, menyebabkan semakin kecil daya yang diterima oleh receiver. Adapun nilai efisiensi terbesar penangkapan daya oleh receiver yaitu sebesar 0.00516 % serta terdapat gangguan pada alat-alat tertentu seperti monitor komputer dan radio.
