Judul: Manajemen Pemupukan Kelapa Sawit (Elaeis guineensis Jacq.) Tanaman Menghasilkan di Angsana Estate, PT Ladangrumpun Suburabadi, Minamas Plantation, Tanah Bumbu, Kalimantan Selatan
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: Studi Pengelolaan Pemupukan Tanaman Menghasilkan Kelapa Sawit  (Elaeis guineensis Jacq.) Di Bukit Pinang Estate, Pt Bina Sains Cemerlang,  Musi Rawas, Sumatera Selatan
Abstrak: The objective of this internship is to increase technical and managerial skill. The internship has done from January12th until June 12th in Bukit Pinang Estate (BPE) Palm Oil Plantation, PT Bina Sains Cemerlang, Musi Rawas, South Sumatera.The methods of this internship are direct and indirect methods. Direct method was conducted by work practice as a field worker and foreman assistant, while the indirect methods was conducted by collecting information from estate archives and literature review. Fertilization applied to keep the amount of soil nutrient in order to ensure plant nutrient fufillment. On yielding crops, fertilization becomes a vital importance because it counts up to 60% of maintenance cost. Therefore it is urgently a correct management of fertilization to optimum efficiency and effectiveness. Condition of rainfall and oblique land topography results fertilization in Bukit Pinang Estate hardly influenced by run off. Fertilization in Bukit Pinang Estate is done by applying concept (4T) that is type precise, dose precise, time precise, and way precise of fertilization. Monitoring done to control quality of fertilizer application in the field . Based on result of observation of quality of fertilization seen 5.2% oil palm which is not fertilized by dredger and 94.8% is fertilized, 41.8% fertilizer is sowed with number of propers while 29.1% too a few, and 29.5% too excessive, 80.2% fertilizer have been disperse in frond, 0.8% in saucer, 5.1% in gate, 3.8% in frond and gate, and 10.1% in frond and saucer. Result of observation of condition of saucer and gate seen 64.4% saucer in condition of dirty, 35.6% clean saucer and 40.4% gate in condition of dirty and 59.6% in condition of clean. Improvement of fertilizer efficiency in BPE is done with making of siel pits, road siel pits, compiles frond " U" Shape, and the application of organic material (JKS).

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.
