Judul: Manajemen Pemupukan Kelapa Sawit (Elaeis guineensis Jacq.) di Bagan Kusik Estate, PT Harapan Sawit Lestari, Kalimantan Barat
Abstrak: The internship was conducted at Bagan Kusik Estate (BKE), PT Harapan Sawit Lestari, West Kalimantan during 4 months. The technical aspects that done during the internship were participate in the plantation activities, i.e : fertilization, weed control, sanitation, leaf sampling, and harvesting. The managerial aspects that done during internship were become an assistant of foreman and assistant of field assistant. The observation done was observing the proper implementation of the rule of the fertilizer application in field. The observations indicated that the fertilizer application on the field has fulfilled these principles, although it could be better by improving the method and dosage aspects. The accuration of fertilization method was 85.4 % for Urea and 80.6 % for Borate. Score of the precise of Urea dosage was 91.1%, therefore the company should be use the standard measuring cup for each fertilizer. The precision of fertilizer types in the fertilizion has reached 100 % for any types of fertilizer. The quantity of fertilizer that applicated in a year likely to affect in fresh fruit bunch production, but the fertilization have a positive correlation with the fresh fruit bunch production. Age and work experience of the fertilization labour doesn’t have a real effect to their work performance. The efficiency of the employe use in the field has been reached with 0.1508 hk ha-1 employement index.

Abstrak: The internship was conducted at Bangun Koling Estate (BKLE), Bumitama Gunajaya Agro, Central Kalimantan during from Februari to Juni 2013. The internship activities aimed adding experience out and learn the management of palm oil plantation especially fertilization management. Collection of data and information carried out by the direct and indirect method. The observation was made is fertilizer effectineness that consist of type, time of application, method and dose of fertilzer. The observation of the efficiency of fertilizer consist of labor and cost efficiency. Nutrient deficiency in BKLE from 2011 until 2012 has decreased for N, K and B but a slight increase in Mg and Cu deficiency

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.
