Judul: Kontribusi Hutan Rakyat terhadap Pendapatan Usaha Tani di Desa Bayasari, Kecamatan Jatinagara, Kabupaten Ciamis, Jawa Barat
Abstrak: The development of community forest is often just for agricultural support, so it is not the main concern and aimed at the development only for bare land or degraded land. As a result, community forest still do not provide the optimal revenue. The existence of an institutional has an important role in the community forest management. The objectives of this research was to determine the characteristics of community forest farmers, patterns and techniques of community forest management as well as to find out the contribution of community forest to household income in the Bayasari Village. The information were collected through interviews and literature study, then analyzed and presented in a descriptive method. The farmer groups in Bayasari Village do not give a big influence on community forest management as there are still many farmers who ignored their program of farmer groups. The analysis showed that the average contribution of community forest product is the largest than another farms products, that is 33.4%.

Abstrak: The pressure on forest resources led to an excessive exploitation of forest resource so that it no longer able to provide optimal benefits even otherwise cause damage and decreased productivity of forest resources. One alternative solution to this problem is to plant forests construction in forest areas that are not productive especially outside Java or other alternatives is the construction of the community forest in the island of Java also outside of Java island. The result of the community forest development activities in addition to the ecologically can support the environment, can also be produced folk wood currently has evolved into a commodity which has a pretty good economic value and perceived by the public that this effort can provide extra income. The community forest as an approach to development of forestry is also prolific on environmental sustainability and an increase in people's income, so that needs to be developed with the better, so as to provide a high timber production and improve the welfare of farmers, while paying attention to power support and function of forests. This research aims to understand further the characteristics and role of the community forest in the Pasir Madang region, particularly from aspect of the community forest’s role against the welfare of the family. This research studies economic condition community forest farmers through the calculation of the balance of the income and spending the community forest farmer families. Further this research examines the contribution of community forest against the peasant household family income and identifying the motivation of farmers in community forest management. Data collected through interview of selected respondens of community forest farmers by using purposive sampling method. Additional information collected through literature studies on secondary data sources from a variety of related government agencies. Respondents farmers who is interviewed in this study consisted of 30 people who come from the village of Pasir madang, Bogor regency, West Java. Based on these studies it is known that most of the people in the village of Pasir Madang managed using agroforestry systems. The community forest in the Pasir Madang village serves as the public savings which can be harvested when the farmer needed the money in relatively large amounts and in urgent circumstances. A pattern of harvesting as it is known in terms of as a “tebang butuh” system. The community forest farmer respondents on site research mature majority in the range of 41-50 years old. The level of education respondents mostly only to elementary schools. In general the community forest farmer has a sideline job in addition to working on their forest field. Farmers in this area have a household incomes larger than level its expenditures, so they are on surplus condition. From the expenditure, allocation largest farmers used to terms of food. The community forest have a very important contribution in the structure of household income of farmers. By using the Sajogyo’s poverty line, more than three quarters of respondents the community forest farmers are above the poverty line or are able to meet the minimum basic needs. The condition is quite encouraging motivation

Judul: Solusi Geometri Schwarzschild untuk Dimensi 4+1 dengan Invarian Rotasi Isotropik.
Abstrak: Metrik Schwarzschild merupakan solusi eksak pertama dari persamaan medan Einstein dengan mangasumsikan metrik statik dan simetris. Metrik Schwarzschild yang ditemukan oleh Karl Schwarzschild masih dalam dimensi 3+1, namun seiring dengan teori-teori terbaru yang menunjukkan bahwa alam semesta tidak hanya di dimensi 3+1. Maka melalui penambahan dimensi, tujuan penelitian ini memperoleh solusi pada geometri Schwarzschild untuk dimensi 4+1 dengan memodifikasi koordinat bola yang invarian rotasi isotropik dan melalui penurunan rumus seperti koordinat bola, simbol Christoffel, dan tensor Ricci. Selain mendapatkan solusi ini, metrik Schwarzschild dimensi 4+1 dapat digunakan sebagai metrik dasar untuk memperoleh solusi blackhole dan wormhole pada dimensi 4+1. Hasil akhirnya, dengan memanfaatkan modifikasi koordinat bola, metrik Schwarzschild dapat dibentuk sehingga diperoleh solusi geometri Schwarzschild untuk dimensi 4+1.
