Judul: Pengembangan Kegiatan Pembinaan Masyarakat Desa Hutan (PMDH) di PT. Ratah Timber, Kalimantan Timur.
Abstrak: Masyarakat di dalam dan di sekitar hutan luar Pulau Jawa umumnya menghadapi masalah kemiskinan dengan pertanian sebagai basis ekonominya. Pola usahataninya masih bersifat ekstensifikasi dan cenderung subsisten, tingkat kesehatan belum memadai serta sarana dan prasarana yang masih terbatas. Hal ini menyebabkan rendahnya tingkat kesejahteraan masyarakat desa yang berada di dalam atau sekitar hutan tersebut. Memperhatikan kondisi sosial ekonomi masyarakat setempat yang tinggal di dalam dan sekitar areal kerja IUPHHK-HA, dan kemampuan yang dimiliki pemegang IUPHHK-HA, pemerintah melalui Keputusan Menteri Kehutanan No. 523/Kpts-II/1997 telah mewajibkan kepada pemegang IUPHHK-HA untuk lebih peduli terhadap upaya-upaya pembinaan masyarakat tradisional yang berada di dalam dan di sekitar areal kerja IUPHHKHA dalam rangka meningkatkan kesejahteraan. Kebijaksanaan ini dikenal dengan Pembinaan Masyarakat Desa Hutan (PMDH).

Judul: Rencana kelola sosial dalam rangka Pembinaan Masyarakat Desa Hutan (PMDH) pada Hutan Tanaman Industri PT Nityasa Idola di Kalimantan Barat
Abstrak: Development of Industrial Forests (HTI), particularly outside Java often faced with complex problems. These problems arise due to the overlapping area between the concession companies to the area controlled by the community. This occurred in the area of Business License Utilization of Forest Plantation Timber (IUPHHK HT) PT. Nityasa Idol in West Kalimantan. Thus, firms in an effort to conduct activities for the development of timber planting need to reconcile with the community, such as every hectare of land that cooperation will be given a replacement of Rp. 60.000/hektar, tree spacing results conducted on the half-cycle (4 years) of Rp. 2.500/m3, obtained from logging during harvest (8 years) of Rp. 5,000 / m3, and the provision of free rubber seedlings were 21 stems / ha. But the company still offers less public attention, this is caused the land still be planted of rubber trees and agricultural shifting cultivation, which assessed the value of a small compensation, and lack of public understanding of the existence of HTI. Social relations among villages surrounding the management company IUPHHK HT PT. Nityasa Idol has been running through a program of activities PMDH. Programs that have run companies, such as training programs and making permanent agriculture, land cooperation with treaty land compensation, educational assistance for teacher salaries, and other social assistance. The program has not been going well so necessary in the evaluation, such as the lack of follow-up assistance training program, not optimal settled agricultural activities, because of lack of socialization and mentoring, the need for optimization of assistance that leads to an increase of places of worship, education, and health, increase cooperation and participation of community leaders, evaluating the content of the land compensation agreement, including the implementation of payment, planting and maintenance activities, lack of employee skills, such as knowledge of the forest industry plants and communication techniques. The problems faced in the implementation of such programs is the number of villages PMDH partner, limited executive power PMDH, lack of good cooperation between companies and local governments, the lack of implementation of activities PMDH, not PMDH activities periodically. But we realize people were also influential factors, such as socio-economic conditions of society, namely shifting cultivation and land activities sebaai fuel economic activity, has not been fully able to accept the changes and innovations from the outside in a positive, business activities are still influenced by customary or traditional.

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.
