Judul: Analisis faktor penentu produksi  Tandan Buah Segar (TBS) tanaman kelapa sawit  (Elaeis guineensis jacq.) di Sungai Bahaur Estate (SBHE), PT Bumitama Gunajaya Agro (PT BGA), Wilayah VIMetro Cempaga, Kotawaringin Timur,  Kalimantan Tengah
Abstrak: The internship started from February 14th to June 14th 2011. The aim of this internship is to find out and analyze about the effect determinant fresh fruit bunch (FBB production factors) of palm oil (Elaeis Guineensis Jacq.) in SHBE, PT Bunitama Gunajaya Agro, Central Borneo. Data used for this internship is time series data from 2008-2010. Independent variable is FFB production. The data were gained primary data (direct method) and secondary data (indirect method). it used two different method. Cobb-Douglas method with double linear regression analysis equation and t-test method. The double linear regression analysis result shows that the variables of employees has positive and very significant effect, variable of fertilizer has negative and is not significant effect, and variable of rainfall has positive effect is not significant towards the palm production. The t-test results shows that ages of plants, SPH and topography has significant toward the palm production. \the coefficient determining (R2) test result shows that the FFB production as dependent variable can be describe by the independent variables (fertilizer, rainfall and employees) for 98.2 %.

Judul: Analisis Produksi Kelapa Sawit ( Elaeis guineensis Jacq.) di Kebun Buatan PT Inti Indosawit Subur, Kabupaten Pelalawan, Provinsi Riau
Abstrak: The internship program has been conducted at PT. Inti Indosawit Subur, Buatan Estate, Pelalawan, Riau from February 13 to May 13 2012. The purpose of this internship program is to learn oil palm cultivation and specifically analyzes the factors that influence the production of palm oil. The data to be collected consist of primary and secondary data. Buatan estate generally have applied the technique of oil palm cultivation in accordance with standard operating procedures that have been established by the company. Based on double linear regression analysis, FFB (Fresh Fruit Bunch) production is influenced by the number of harvesting working days and the amount of harvester output. The coefficient of determination (R2) generated that variables of FFB production as dependent variable can be describe by the independent variables (harvesting working days, amount of harvester output and rainfall) for 98.3%. The main problem is the decrease in crop productivity for plants older than 22 years as the age of the plant is already above the maximum age of the average productivity of oil palm.

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.
