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.

Abstrak: The internship was conducted at Bangun Koling Estate (BKLE), Bumitama Gunajaya Agro, Central Kalimantan during from Februari to Juni 2013. The internship activities aimed adding experience out and learn the management of palm oil plantation especially fertilization management. Collection of data and information carried out by the direct and indirect method. The observation was made is fertilizer effectineness that consist of type, time of application, method and dose of fertilzer. The observation of the efficiency of fertilizer consist of labor and cost efficiency. Nutrient deficiency in BKLE from 2011 until 2012 has decreased for N, K and B but a slight increase in Mg and Cu deficiency

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.
