Judul: Manajemen Pemanenan Kelapa Sawit (Elaeis guineensis Jacq.) di Kebun Sei Air Hitam, PT Perdana Intisawit Perkasa, Rokan Hulu, Riau
Abstrak: The internship program has been conducted at Sei Air Hitam Estate, PT Perdana Intisawit Peerkasa, Rokan Hulu, Riau from February to May 2012. The purpose of this internship program is to study the technical and management of oil palm cultivation, especially for oil palm harvesting aspects. The data consisted of primary and secondary data. Generally, farm quality and fruit grade in Sei Air Hitam Estate are good with ratio of loses fruit below the standard that has been stated by the company about 3% and fruit ripenes average reaching more than 95%. Management of Sei Air Hitam estate is good with harvest efficiency percentage rate of 94.4% and 5.6% losses. The main problem in the harvesting is a crop rotation due to the national holiday and many rainfall intensity that crop rotation should be improved so that the oil obtained in accordance with market demand.

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: Grup Abelian Berhingga dari Barisan Genomik DNA  (Deoxyribonucleic Acid)
Abstrak: Informasi genetik yang memprogram semua aktivitas sel terdapat dalam bentuk kode di dalam molekul DNA. Grup kodon dari basa nukleotida DNA {A, C, G, U} tidak dapat merepresentasikan daerah non kode dalam genom yang disebabkan oleh mutasi penghapusan serta penyisipan pada barisan genomik DNA. Dalam karya ilmiah ini grup kodon diperluas dengan menambahkan huruf O untuk menandakan mutasi penghapusan atau penyisipan pada kodon untuk semua triplet diperluas 1 2 3 X X X dengan i X Î{O, A, C, G, U} dari barisan genomik DNA. Grup kodon yang diperluas isomorfik dengan grup bilangan bulat modulo 125. Grup abelian berhingga dari barisan genomik DNA yang dibentuk dari himpunan seluruh pasangan terurut triplet ekson dan intron pada untai DNA isomorfik dengan grup jumlah langsung bilangan bulat modulo 64 dan 125. Kemudian grup abelian berhingga tersebut direpresentasikan sebagai grup jumlah langsung 2-grup dan 5-grup homosiklik. Bagian barisan genomik DNA tanpa penyisipan membangun blok gen yang direpresentasikan oleh 2-grup homosiklik, sedangkan bagian barisan genomik DNA yang dipengaruhi oleh penyisipan direpresentasikan oleh 5-grup homosiklik.
