Judul: Manajemen Pemanenan Kelapa Sawit (Elaeis guineensis Jacq.) di Kebun Bagan Kusik Estate, PT Harapan Sawit Lestari, Ketapang, Kalimantan Barat
Abstrak: The internship activities were conducted in Bagan Kusik estate, PT Harapan Sawit Lestari, West Kalimantan, starting from February 10 to June 10, 2014. The internship activity had given experience and improve the ability of students or skill in oil palm plantations. Harvesting management which had concerned such as crop rotation, crop density figures, ripe harvest criteria, work performance, menpower, and result of transportation. The crop rotation and menpower had been analyzed by using t-student test and corelation test. The result of t-student test showed that there is a significant difference between the standard harvest interval with the realization of production. Based on the results of correlation test is known that the factors of age, length of employment, education level positively correlated to the production of palm oil. The harvesting management implementation from preparation harvest, how to harvest, and transport the FFB (Fresh Fruit Bunches) to the mill that had been implemented with good, so that the production of palm oil each year has increased.

Abstrak: Internship program provides knowledge and skills in aspects agronomy of oil palm, both technical and managerial. This internship activities were started from February 2014 to June 2014 at Adolina Estate PTPN IV Persero, Serdang Bedagai, North Sumatera. Intership activities included, worker in the field as laborer, as supervisor and field manager. Management of harvesting included harvester, harvest capacity, harvest quality, and production as well as productivity of the palm. Secondary data were collected form literature and field devision archives such as monthly and annuals reports, as well as documentation of the field activities. Generally the needs of the harvester in Adolina Estate has been sufficient, but the quality and capacity of the harvest still low. Ripe fruits were not harvested and there were still many loosed fruits which has not been collected in the field. The production and productivity of palm per year of transplanting is not based on target. Better quality harvester and more intensive control by supervisor will improve quality and quantity of harvest.

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.
