Judul: Kontribusi Pembinaan Usaha Kebun Karet Rakyat Terhadap Kesejahteraan Masyarakat Desa Hutan di PT. Sarpatim, Kalimantan Tengah
Abstrak: Forest Village Community Development (PMDH) is a community development to improve welfare of community who live in and surronding forest area and to prevent deforestation. This study was aimed to determine contribution of small holder rubber palantation business (KKR) to the income of the people and the relation to forest encroachment by public. The main data used are the characteristics of the respondent, the respondent's total incomes and expenditure, and data rate of forest encroachment. KKR activities conducted by PT. Sarpatim has contributed to improve the welfare of society approximately 50% of total incomes. The factors that significantly influence to farmer income from rubber business is the rubber gum production, gum collection frequency, and employment status of rubber farmers. KKR has been successful to increasing people's income, but have not been able to reduce the rate of forest encroachment by people, it could be caused by increase population and ill-defined property rigths of state forest.

Judul: Study of the socio-economic condition of the village communities around the IUPHHK-HA PT. Sarmiento Parakantja Timber in Central Kalimantan
Abstrak: Perusahaan sebagai salah satu pelaku dalam pembangunan ekonomi, sudah selayaknya tidak hanya bertujuan memperoleh keuntungan finansial, namun juga perlu berkontribusi bagi masyarakat dan lingkungan di sekitarnya. Oleh karena itu perlu dilakukan penelitian keadaan sosial ekonomi masyarakat sekitar hutan PT. Sarmiento Parakantja Timber yang merupakan perusahaan IUPHHK-HA. Tujuan dari penelitian ini adalah mendapatkan informasi kondisi demografi, keadaan social ekonomi-budaya, mata pencaharian dan pendapatan, opini mengenai peran hutan, dan opini bentuk kemitraan dan partisipasi masyarakat dalam pengelolaan hutan. Tahapan penelitian ini terdiri dari pengumpulan data, pemilihan responden, pengolahan dan analisis data. Hasil penelitian menunjukkan perusahaan selama ini telah melakukan pembinaan terhadap masyarakat desa di sekitarnya melalui program kesehatan, pendidikan, pengembangan masyarkat, keagaman dan adat. Sosial-ekonomi masyarakat sekitar PT. Sarmiento Parakantja Timber tergolong ke dalam masyarakat sejahtera, dengan pendapatan di atas Upah Minimum Kabupaten (UMK), mata pencaharian utama adalah usaha tani ladang berpindah dan tingkat pendidikan masih rendah. Opini mengenai peran hutan 70% menyatakan fungsi hutan sebagai pencegah bencana banjir dan tanah longsor, 90% menyatakan hutan sebagai tempat untuk mengambil kayu dan hasil hutan lainnya. Opini bentuk kemitraan dan partisipasi masyarakat dalam pengelolaan hutan adalah sangat baik., The company as one of the actors in economic development, should not only aim to obtain financial benefits, but also needs to contribute to the community and the surrounding environment. Therefore, it is necessary to conduct research on the socio-economic conditions of the community around the PT. Sarmiento Parakantja Timber which is an IUPHHK-HA company. The purpose of this study was to obtain information on demographic conditions, socio-economic-cultural conditions, livelihoods and incomes, opinions on the role of forests, and opinions on forms of partnership and community participation in forest management. The stages of this research consist of collecting data, selecting respondents, processing and analyzing data. The results of the study show that the company has been providing guidance to the surrounding village communities through health, education, community development, religion and custom programs. Socio-economic community around PT. Sarmiento Parakantja Timber belongs to a prosperous society, with income above the Regency Minimum Wage (UMK), the main livelihood is shifting farming and the level of education is still low. Opinion on the role of forests 70% stated the function of the forest as preventing floods and landslides, 90% stated the forest as a place to collect wood and other forest products. The opinion of the form of partnership and community participation in forest management is very good.

Judul: Kajian Stabilitas Inti Super Berat dengan Nomor Atom 110 Sampai dengan 200 Menggunakan Model Inti Tetesan Cairan
Abstrak: Liquid droplets of nucleic models can be derived equations to estimate the binding energy, binding energy per nucleon, the most stable isotope, and the condition of the occurrence of spontaneous fission. The equations are then converted into a numerical equation form which is then inserted into the MATLAB programming language. Based on the results of the calculations have been carried out in this study, super-heavy nuclei will undergo spontaneous fission in the Z = 135. At Z = 135 the energy needed to create the nucleus undergoing fission or activation energy is very small at around 0:48 MeV. Above Z = 135 the activation energy is negative, it means to form a nucleus with Z> 135 needed some energy. Then at Z = 135 the ratio Z2 / A is 48.86, almost reaching requirement ratio Z2 / A where the nucleic will undergo spontaneous fission is 49. Binding energy per nucleon for super-heavy nuclei up to Z = 200 is about 7 - 5.5 MeV, together with a range of light nuclei are stable. So there may be a super-heavy nuclei are stable at Z <135 and above Z> 135 there will be no stable nucleic
