Abstrak: The objective of this study was to obtain some informations about sago palm cultivation especially in nursery and know the effect of sucker weight and liquid manure application to the vegetative growth of sago sucker at polybag nursery system. This experiment held in PT. National Sago Prima, Selat Panjang, Riau from February to June 2011. The primary data were found by direct methods, it included the following activities in cultivation of sago palm, and did experiment in the field. The secondary data were found by indirect method, interviewed and discussed with the company staff and study literature to get more informations. The special aspect was find by arranged in split plot design, where the main plot was sucker weight with three levels (50-200 g, 200-500 g, and 500-800 g) and the subplot was four levels of liquid manure application (0, 2, 5, and 8 ml/l) with three replications. The results showed that there was no significantly different in the vegetative growth of sucker by liquid manure application. The sucker weight treatment showed significantly different to survival rate, leaf length, number of leaves, and percentage of expanded leaves. The larger suckers produced higher of leaf length. However, larger suckers didn’t always produce higher percentage of expanded leaves and higher survival rate of suckers in comparison to smaller ones. The sucker weight 200-500 g was the best sucker size to the vegetative growth of suckers

Abstrak: This intenship was held in Nasional Sago Prima company, Selat Panjang, Riau from February to June 2011. The Method are direct for getting primary dara and indirect for secondary data. Secondary data takes from technique activity in tthe field and the research. The experiment was conducted to get more information on the effect sucker weight and time after nusery to to sucker growth in plantation are. The treatment will be tested sucker growth with the different weight and age of sucker in raft nursery system. The first treatment on sucker 2-4 kg (BI) and 4-8 kg (B2), teh second treatment on sucker is 2 weeks after nussery (P1), 4 weeks (P2), 8 weeka (P3) and 12 weeks (P4), the result shown treatment on 2-4 kg (B1) is better than nursey was significant different in presentation survival rate bt in vegatative growth haven't significantly difference. The sucker 123 weeks after nursery was the best sucker age to the vegetative growth of suckers.

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.
