Judul: Identifikasi Parameter Agronomi untuk Pengembangan Taksasi Produksi Kelapa Sawit (Elaeis guineensis Jacq.) di Angsana Estate, PT. Ladangrumpun Suburabadi, Minamas Plantation, Tanah Bumbu, Kalimantan Selatan.
Abstrak: The purpose of this final assignment was to determine agronomic and agroecological characters responsible to production estimation of oil palm fresh fruit bunches. The studies was conducted at PT. Ladangrumpun Suburabadi, Minamas Plantation, District of Tanah Bumbu, South Kalimantan from February 15th to June 15th 2010. The assignment composed of several works, i.e., as field worker for two months, as assistant foreman for one month, and as estate assistant for one month. Special observation was conducted as additional activity, e.g. to examinate the agronomic and agroecological characters which were expected affected oil palm production such as climates, land suitability, and agronomy of oil palm. According to test of t-parcial, indicated that climatic factors played an important role in the production of oil palm. Air humidity in the 6 months prior to harvest (MPH), the sun shines intensities on 18 MPH, rainfall on 6 MPH, rainy days on 18 MPH, water deficit at 0 and 24 MPH, as well as plant age and fertilizer including the factors determining the production of oil palm. Production forecasting modeling performed by multiple linear regression analysis, from the seven variables significantly affected the production of oil palm, of which obtained six combination of regression. Multiple linear regression equation no. VI was the closest to actual production. This multiple linear regression equation VI can be used to predict the annual production of oil palm in Angsana Estate for 5-11 years old plants by adding up monthly production forecast for a year. It is note worthy that regression equation VI dependent on fertilizer aplikation, number of rainy days and sunshine at 18 MPH, water deficit at the 24 MPH, and present plant age data.

Abstrak: The internship was conducted at Angsana Estate, PT Ladangrumpun Suburabadi, District of Tanah Bumbu, South Borneo on February 15th to June 15th 2010. The internship aims to increase knowledge about the cultivation of oil palm both technical and managerial, in addition, an internship is to review the management of oil palm crop fertilization on crop yield, analyze the factors that affect the efficiency and effectiveness of fertilization and its influence on palm oil production. Data collection was conducted on the collection of primary data and secondary data. Primary data obtained by observation and analysis of the efficiency (time, cost, and labor), effectiveness (the right time, right dose, right type, and the right way), nutrient deficiency, the productivity of oil palm, interviews with employees, foremen, and assistant. Secondary data obtained from data given by the cation garden and library administration. The data obtained was analyzed by qualitative descriptive method. The outcomes of this internship showed that fertilization in Angsana Estate has been realized with good accordance with the budget and in compliance with the concept of the effectiveness of the right kind and proper manner, but has not met the concept of timely and appropriate dosage. Angsana Estate also has met the concept of fertilizer efficiency that is efficient time, cost and labor. Nutrient deficiency in oil palm plantations do not provide significant effect on palm oil production because fertilizer has been adjusted based on the results of leaf analysis done by Minamas Research Centre. The existence of difference in productivity Angsana Estate with existing standards may be caused by variables other than fertilization.

Judul: Grup dan Homomorfisma Grup pada Rubik Revenge
Abstrak: Rubik cube is a kind of puzzle game. A player must arrange rubik sides, which have been disordered, back to the position where every side has the same colour. This paper does not focus on the settlement solution, but instead on proving the existence of a group homomorphism between rubik movement group and S96 symmetric permutation group in rubik revenge. Firstly, it has been proved that rubik movement set is a group. Then, it also has been proved that the M set, which contains numeric labels of 1 until 96 in cubinos sides, is S96 symmetric permutation group.
