Judul: Pengelolaan Pembibitan Karet (Hevea brassiliensis Muell Arg.) di Kebun Riset Balai Penelitian Sembawa, Sumatera Selatan
Abstrak: Internship activities was undertaken to improve the knowledge, skills, and field experience, and aims to determine the rubber nursery management and technique specialy about rubber seedling. Internship activities carried out at the Rubber Research Sembawa, South Sumatra from February to June 2014. Urusan Bahan Tanam (UBT) is combination between nursery and Prossesing Unit oil palm seeds (UPKS), so UBT has its own organization structure. Production planning of nursery is still constrained by the limitation land of rootstock, so that planning have to wait rejuvenation old rubber. Grafting is one of rubber propagation activities. Oculator capacity to perform of grafting already compliant but grafting success rate still low was 73.3%. The quality of rootstock and scion are good, but the rootstock have bad quantity because limitation of land. Certification activities conducted by the Board of Certification and Crops Plantation. The proccess purchasing of rubber seedling direcly in UBT office or in marketing departement of Rubber Research Sembawa can be done. Consument have to pay 30% advance money from all payment of rubber and transportation of seed were provide by the consumers

Judul: Pengelolaan Pembibitan Kelapa Sawit ( Elaeis guineensis Jacq) Di Kebun Teluk Bakau, PT Bhumireksa Nusa Sejati, Kabupaten Indragiri Hilir, Provinsi Riau
Abstrak: This internship was aimed to acquire the knowledge, technical skills and management of trainer students to work professionally, increase the soft skill of students to prepare themselves to be professional worker, especially in management aspects of oil palm nursery. This internship has been done in Teluk Bakau Estate, PT Bhumireksa Nusa Sejati, since February to June 2014. The technical aspects that were carried out during the internship consist of following the existing activities in the oil palm nursery in Teluk Bakau Estate, fertilizing the immature plants, weed control on immature plants, and harvesting. Mananejerial aspects were performed as a companion foreman and division assistant. Observation were carried out on germination growing percentage, seedling plant height, and of abnormal seedlings percentage in the pre-nursery. From observation, we found that seedling plan height increase about 2 cm/week, germination growing was 95.9 percent, and abnormal seedlings was 5.9 percents.

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
