Abstract

The objective of this research was to study of cultivation techniques palm oil independent farmers and social aspects to palm oil production. This research has conducted in Lubuk Dalam District Siak Regency from August 2014 until October 2014. The research was conducted using survey and the sampling used for this research purposive sampling. Consist of 60 sample, based on 10% level of representation. 30 sample drawn from Rawangkao Village and 30 sample drawn from Lubuk Dalam Village. The parameters studied were, land clearing, the origin of the seeds, size of planting holes, seed age, plant spacing, pruning, control of weeds and fertilization. The results show that the average production palm oil of farmers are still very low at less than 50% when compared to the average production of palm oil of PPKS Medan on mineral lands in general. The low production of palm oil cultivation techniques of farmers due to conducted as seed origin, plant spacing, pattern spacing, the size of the planting hole, transplanting seedlings into the ground, fertilizing, are still quite low level of the appropriate palm oil cultivation techniques application in the field.   Keywords: Cultivation Techniques Palm, Independent Farmers, Siak Regency

Abstract

Prestressed concrete bridge STA 6+850 Provincial Road Penggal Binjai-Langsa Freeway is one of the footbridges connecting the fast road from Binjai To Langsa with a total bridge length of 30 meters and a total bridge width of 26.90 meters (2 lanes). Preparation of the prestressed walkway for Provincial Road STA 6+850 Freeway at the Binjai-Langsa joint is based on RSNI-T-02-2005 for loading on the walkway. Based on RSNI-T-02-2005, the loading for the prestressing walkway spans 30 meters with a total of 3 tendons, where one tendon is 19 standards with a diameter of 12.7 millimeters. The tension in the flexural compression fiber due to the influence of prestressing, dead load and live load is 0.45 fci' (13500 kPa). Control of overturning stability in the X and Y directions on the abutment, the number of safety (SF) against overturning is greater than the allowable SF = 2.2 (safe). The carrying capacity of the pile foundation bearing capacity (Qg) was analyzed based on SPT data, the value obtained was 87207.33 kN using Meyerhoff's (1956) method from SPT field data.
