Judul: Manajemen Panen Kelapa Sawit (Elaeis Guineensis Jacq.) di Kebun Tambusai PT. Panca Surya Agrindo, First Resources Ltd., Kec. Tambusai, Kabupaten Rokan Hulu, Riau.
Abstrak: The purpose of this internship program was to improve technical and managerial skills on oil palm plantation. The internship was conducted at Tambusai Estate, PT. Panca Surya Agrindo, First Resources Ltd; Tambusai, Rokan Hulu, Riau on 13 February to 12 May 2012. Primary data from field observations devoted to the preparation of fruit harvesting, and other technical and managerial aspects of harvesting, harvesting system of premiums, and production of fresh fruit bunches. Secondary data were obtained from the archives of the company for 5 years. The data were analized by using deskriptive method, percentage (%) and average value. The data and fild observations indicated that there were harvesting management problem needed to be improved. The problem related with the back number of harvester, caused too high harvest capacity of each harvester, and the less accurate of yield prediction. Asno the consequency of the problem was the late of transportation to the mill and the processing of FFB at the mill

Abstrak: The internship program was conducted at Sei Air Hitam (SAH) Estate, PT Perdana Inti Sawit Perkasa I, First Resources, Rokan Hulu, Riau from February to June 2014. The purpose of this internship program is to increase knowledge and experience, to built attitude and work skill and also learn the right palm oil harvest processing technically and management. The data consisted of primary and secondary data. Primary data that observed were harvest forecasting, harvest density, harvest interval, harvest labour, harvest quality and quality of palm oil. Generally, SAH Estate has implemented procedures work properly in every activity like oil palm cultivation on the harvesting activity. Problems in harvesting that need to be addressed include increased intensity of the rain and national holidays that causes harvest interval increased. Harvest management at SAH Estate should be optimized to comply to the company SOP.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
