Judul: Strategi Pengembangan Usaha Perkebunan Kelapa Sawit pada PT Perkebunan Nusantara III (Persero) Medan, Sumatera Utara
Abstrak: PT Perkebunan Nusantara III merupakan sebuah perusahaan perkebunan milik negara yang berpusat di Sumatera Utara. Lingkungan usaha perkebunan, terutama kelapa sawit sangat menarik dikarenakan peningkatan permintaan terhadap produk kelapa sawit dan persaingan yang semakin ketat. Maka dari itu diperlukan suatu pengembangan usaha yang sesuai bagi perusahaan. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor internal dan eksternal perusahaan, memformulasikan alternatif strategi, serta menentukan prioritas strategi yang paling tepat untuk diterapkan oleh PT Perkebunan Nusantara III. Alat analisis yang digunakan adalah matriks IFE, matriks EFE, matriks IE, matriks SWOT, dan matriks QSP. Matriks IFE dan EFE menunjukkan bahwa perusahaan memiliki kondisi internal rata-rata dan kondisi eksternal yang baik. Matriks IE menunjukkan bahwa perusahaan berada pada kuadran kedua. Formulasi alternatif strategi yang dibuat menggunakan matriks SWOT menghasilkan tujuh alternatif strategi. Prioritas strategi yang dihasilkan menggunakan matriks QSP yaitu meningkatkan produktivitas dan kualitas produk pada setiap unit kebun.

Judul: Strategi Pengembangan Usaha Perkebunan Kelapa Sawit pada PT Perkebunan Nusantara 4 Medan Sumatera Utara
Abstrak: Indonesia is an agricultural country, which the agricultural sector is as one of the biggest sector that contribute for the national GDP. Plantation is a part of agricultural sector that has palm oil as one of the biggest commodity of it. The high demand of palm oil from domestic and also abroad is one of the opportunity for many palm oil companies in Indonesia. Therefore, business development strategy is needed to fulfill the high demand of palm oil to catch the opportunity. Internal Factor Evaluation (IFE) and External Factor Evaluation (EFE) Matrix are used to identify internal environment (strength and weakness) and external environment (opportunity and threat) that can be used by top management to make a grand strategy. A grand strategy was obtained by I-E Matrix and SWOT Matrix. Finally the best strategies will be chosen by QSPM (Quantitative Strategies Planning Matrix). The result of the analysis showed that the best strategy for PTPN 4 is increasing the efficiency of production in this palm oil plantation firm.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
