Judul: Manajemen Panen Kelapa Sawit (Elaeis guineensis Jacq.) di Kebun Sei Dadap, PTPN III, Asahan, Sumatera Utara
Abstrak: The internship program was conducted at Kebun Sei Dadap, PTPN III, Asahan, North Sumatera from February 11th to June 10th 2013. This internship program was held to fulfill the purpose for studying the oil palm cultivation technique, understanding the factors related to oil palm harvesting process, and gaining experience and hard skill on oil palm production. The need of harvesters have become very decisive for oil palm production. Harvesters disciplinary level was still low as it was shown in areal harvest quality and became a problem that needed to be solved to increase more the plantation production quality. Kebun Sei Dadap had generally increased their production for three years in a row since 2008 to 2010, but then decreasing slightly for the last two years, since 2011, eventough the size of plantation areal has not significantly changed

Abstrak: Internship aims to improve the ability and comprehension in the management of oil palm plantation. Internship implemented in Adolina Estate, PTPN IV. In the implementation of internship, harvest management in the oil palm harvesting was accentuated to observed and studied. Observation in harvest management consists of harvest rotation, harvest density, assessed daily production, harvester requirements, criteria of ripe harvest, harvester capacity, quality fruit, and transporting the fruit to oil palm mill. Data from observation were analyzed quantitatively using the average, percentage, and standard deviation (descriptive statistics) as well as the t-student test (comparison). The results from analyzed showed that harvest management of oil palm in Adolina Estate need to be improved. It is due to harvester capacity is lower of standard company and the high production percentage of fruits have not quality. The low capacity of harvesters affect the calculation of harvester requirements and disruption of harvest rotation. Harvest rotation is disturbed affect the high production percentage of fruits have not quality. Adolina Estate has implemented assessed harvest density quite accurately to the realization of the harvest density. The accuracy of the assessed harvest density to realization of harvest density affect the accuracy of the assessed daily production as well as calculation of harvester requirements and transport harvest.

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.
