Judul: Manajemen Panen Kelapa Sawit (Elaeis Guineensis Jacq.) Di Mandah Estate, Pt Bhumireksa Nusasejati, Minamas Plantation, Indragiri Hilir, Riau
Abstrak: Kegiatan magang dilaksanakan di Kebun Mandah, PT Bhumireksa Nusasejati, Minamas Plantation, Kabupaten Indragiri Hilir, Provinsi Riau mulai dari bulan Februari 2015 sampai dengan Juni 2015. Kegiatan magang ini bertujuan untuk mempelajari teknik dan manajemen budidaya kelapa sawit secara umum khususnya pemanenan kelapa sawit. Kegiatan panen di Divisi I Kebun Mandah menggunakan sistem Block Harvesting System non-Division of Labour yaitu program implementasi pengerjaan kegiatan panen yang terkonsentrasi pada satu seksi yang harus diselesaikan dalam satu hari dimana penyelesaian hancak dari potong buah dan kutip brondolan dilakukan sepenuhnya oleh satu pemanen. Secara umum kualitas mutu buah dan mutu hanca di Kebun Mandah sudah baik dengan rasio kehilangan hasil sudah di bawah standar yang telah ditetapkan oleh perusahaan dan rata-rata kematangan buah sudah mencapai standar 95%. Aspek panen yang menjadi kendala yaitu unit angkut buah yang lambat dalam pengangkutan ke pabrik kelapa sawit menyebabkan banyak buah menginap di lapangan.

Abstrak: The harvest management at peatland oil palm plantation is one of the most important factors to reach high fresh fruit bunch (ffb) production. The purpose of this apprenticeship activity was to improve knowledge, ability and work skill of student in order to comprehend in harvest management at oil palm plantation. This apprenticeship took place in Mandah Estate, PT. Bhumireksa Nusasejati, Minamas Plantation, Indragiri Hilir, Riau, from February 2012 to May 2012. Data and information were collected with direct methode and indirect methode. Direct methode was collected by observation and discussion with harvester, foreman, and field assistant. Indirect methode was collected from company data and company record. The harvest activity in Mandah Estate divition 5, uses Block Harvesting System non-Division Of Labour (BHS non-DOL). This system was implementation programs of harvest activity that focus to finished harvest in one section a day. The result of harvest activity in Mandah Estate divition 5 runs well, a shown by good field quality with 0.2 lost fruit per plant, 95.3 % of ripe fruits and 0% unripe fruit. The most obstacle of harvest aspec in Mandah Estate was the transport unit of ffb very slow and caused the uncarry of ffb.

Judul: Pengaruh Pairing pada Isotop Sn dengan Menggunakan Pemodelan Sembilan Tingkat Energi
Abstrak: Formation of the neutron-rich tin isotopes (Sn isotopes) is the one of the interesting topics in the field of nuclear reaction, especially regarding the stability of the heavy nuclei. Calculations of total energy using the BCS approach using five energy levels can only calculate the total energy up to Sn50132. On the other hand, the experiment continues and has exceeded the formation of isotopes. Therefore, there is need for a new model to accomadate more neutrons. In this research, Sn isotopes is modelled using nine energy levels and constant interaction potential to explain the pairing phenomenon up to Sn50154. However, to obtain more accurate results, other methods to minimize the differences with the experimental results are clearly needed here.
