Judul: Manajemen Kelapa Sawit (Elaeis guineensis Jacq) Di Sekunyir Estate Minamas Plantation Kalimantan Tengah
Abstrak: Kelapa Sawit (Elaeiss gueenensis Jacq) merupakan penghasil minyak nabati penting di Indonesia. Produktivitas kelapa sawit dipengaruhi berbagai faktor diantaranya adalah manajemen pemanenan. Penelitian ini mempunyai tujuan khusus yaitu mempelajari dan memahami manajemen pemanenan kelapa sawit, serta menganalisis faktor-faktor yang mempengaruhi efektivitas dan efisiensi pemanenan kelapa sawit. Pengumpulan data dilakukan dengan metode langsung dan tidak langsung untuk mendapatkan data primer maupun data sekunder. Pengamatan di lapang dilakukan dengan mengikuti delapan pemanen pada sistem Division of Labour (DOL) dan empat tim panen pada system 1 Cutter and 2 Carrier ( C1R2). Perubahan sistem panen dari sistem DOL menjadi sistem C1R2 memiliki dampak yang baik terhadap manajemen panen serta produktivitas dari tim panen. Sistem C1R2 memiliki hasil 5-7% lebih tinggi dari sistem DOL dalam memperoleh buah matang dan memiliki jumlah buah busuk lebih sedikit yaitu sekitar 2,6% dibandingkan sistem DOL yang mencapai 8%., Palm oil (Elaeiss gueenensis jacq) is an important vegetable oil in Indonesia. Palm oil productivity is influenced by various factors including harvest management. This research has specific objectives to be achieved, namely studying and understanding the management of palm oil harvesting, and analyzing the factors that influence the effectiveness and efficiency of palm oil harvesting. Data collection obtained by direct and indirect methods to find primary and secondary data. Field observations were conducted by following 8 harvesters on the Division of Labour (DOL) system and 4 harvest teams on the 1 Cutter and 2 Carrier (C1R2) system. The conclussion of this research is the changing the harvest system from the DOL system to the C1R2 system has a good impact on crop management as well as the productivity of the harvest team. The C1R2 system has a yield of 5-7% higher than the DOL system in obtaining ripe fruit and has a fewer number of rotten fruits which is around 2.6% compared to the DOL system which reaches 8%.

Abstrak: Palm management thesis was carried out to study the cultivation of palm oil in general, in particular to understand the various aspects and factors which support the process of harvesting of oil palm. Thesis (internships) in palm oil plantations, PT Ciliandra Perkasa, First Resources Ltd., village Siabu, district of Kampar regency, Salo, Riau Province, during a four month is the month of February to June 2013. This thesis Plantations underway in using direct and indirect methods. The direct method is used to collect data and information with the interview. The indirect method is a method used to acquire secondary data from the plantations. Results of the analysis of several factors that support the harvesting on afdeling V in general have shown good results. These factors include the harvest criteria with an average of 2 kg-1 item, total harvest labor has labor needs afdeling, 6/7 harvest rotation, and efficiency of harvest showed good results with efficiency >95%. However, the value of the number density of crops still under 15% with an average of 11.77% and the supervision and monitoring of the quality of hanca still less than optimal. Results of comparative analysis of some variables between afdeling I and V differ markedly on the production of fresh fruit bunches of 1485.8 kg/ha (afdeling I) and 1011.7 kg/ha (afdeling V), fruit off 165.5 kg/ha (afdeling I) and 45.5 kg/ha (afdeling V), weight per bunch 11.0 kg/ha (afdeling I) and 13.8 kg/ha (afdeling V), oil production 1651.4 kg/ha (afdeling I) and 1084.9 kg/ha (afdeling V) achievements of kg 1608.7 kg/ha (afdeling I) and 1288.2 kg/ha (afdeling V), and the achievements of ha 3.2 ha/person (afdeling I) 4.8 ha/person (afdeling V) however did not differ markedly on the number of trees, number of bunches of tree, bunches and bunches of accomplishment. It shows that the afdeling I better compared to the comparison of afdeling V based on the topographic form afdeling I flat to wavy and bumpy and hilly afdeling V.

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.
