Judul: Manajemen Pemanenan Kelapa Sawit (Elaeis guineensis Jacq.) di Kebun Gunung Pamela PTPN III, Sumatera Utara
Abstrak: Intership program gave knowledge, skill, and experience in technical aspect of conducting of oil palm and lead of the employees management. This activity was started from February to June 2013 in Gunung Pamela Plantation PT. Perkebunan Nusantara III, North Sumatera. Observation was examined with statistical data analyse such as corelation and t-dunnet test. Harvest rotation, harvest density, management of labour, and harvesting supervision were important aspect in harvesting activity. Result of harvest density estimation analysis was not significantly different, the result of corelation to harvester quality was observe from the age harvester, work experience and education level to output of harvester (amount of palm oil fruit) was not significantly different, weak, and directional except education level that a instruct contrary. Result of t-dunnet test of work experience didn’t affect the real output of harvester. The age of harvester that less than and more than 30 years old, according to result of t-dunnet test, was not significantly different to the output. Productivity of palm oil in Gunung Pamela Plantation PT. Perkebunan Nusantara III haven’t reached to marihat standard.

Judul: Manajemen Pemupukan pada Tanaman Menghasilkan (TM) Kelapa Sawit (Elaeis Guineensis Jacq.) di Kebun Gunung Pamela PT. Perkebunan Nusantara III, Tebing Tinggi, Sumatera Utara
Abstrak: Kegiatan magang ini dilaksanakan pada 11 Februari hingga 10 Juni 2013 di Kebun Gunung Pamela PT.Perkebunan Nusantara III. Kegiatan magang bertujuan untuk memberikan pengetahuan mengenai budidaya kelapa sawit, serta meningkatkan kemampuan manajerial mahasiswa dalam mengolah kebun kelapa sawit . Pemupukan kelapa sawit yang efektif dan efisien harus memenuhi prinsip 5T (Tepat Dosis, Tepat Waktu, Tepat Cara, Tepat Tempat dan Tepat Jenis). Pengumpulan data dan informasi dilakukan dengan metode langsung dan tidak langsung. Secara umum pemupukan di Kebun Gunung Pamela (KGPMA) belum memenuhi kaidah 5T. Pengamatan yang dilakukan terhadap ketepatan jenis, waktu, cara dan tempat pupuk yang diaplikasikan sudah tepat namun ketepatan dosis dengan rata-rata 84.4% masih dibawah standar perusahaan. Tingginya gejala defisiensi hara terutama hara B dan pemakaian tenaga kerja yang kurang efisien

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
