Abstract

One way to produce good seeds is from fertilization factors, both artificial fertilizers or biological fertilizers. Palm oil growing media is soil in which there are several nutrients needed by plants, one of which is Phosphor (P). The role of P in plants is important for cell growth, formation of fine roots and root hairs, strengthening the stem stands. However, there are still many P nutrients that are bound in the soil so with that one effort to overcome the low phosphate available in the soil is by utilizing a group of microorganisms. Microorganisms and organic matter, each of which can produce organic acids that chew metal in the soil so that phosphate becomes available to plants.

Abstract

This study aims to determine the effectiveness of the Palm Oil Fresh Fruit Bunch transportation system. This research was conducted at Air Batu Estate Afdeling I PTPN IV, which is located in Asahan Regency, North Sumatra. This research was conducted in July to August 2018. The method used in this study was a descriptive method by taking data in the field about the arrangement of transportation of oil palm fresh fruit bunches. Observations made included information on the Air Batu estate, estimated daily harvest, transport transportation, daily production and transportation, and obstacles or obstacles to the transportation process. Based on observations made, it was found that: (1) The average loading process time for the rotation II was 64.22 minutes, the average time of the transport process from Afdeling I to PKS for the rotation II was 28.68 minutes, and the average time average unloading process at PKS is duration 18.30 minutes, (2) Based on the SPC for the value of Cp and Cpk for loading, transporting and unloading processing time can be said to be less effective with Cp and Cpk values <1, (3) Average number of trips per day in August 2018 which is 2 trips / day. The theoretical trip calculation results are 4 trips / day, (4) The average number of daily harvest production in August 2018 in Afdeling I of Batu Air Farm 34,542 kg TBS. Daily crop yields are still below the daily harvest planning target of 38,307 kg FFB, and (5) The speed of the truck is 12.6 km/hr, this is due to the damaged and bupy road.

Abstract

In terms of felling the old palms, there are two techniques for oil palm replanting: conventional and underplanting. The conventional method involves felling all of the old palms at once. Under the underplanting technique, on the other hand, the old palms are felled in stages, and the new palms are planted among the remaining old palms. The purpose of this study was to compare the performance of immature oil palms when replanting old palms using conventional and underplanting techniques. The research was conducted in Kebun Rambutan, PT Perkebunan Nusantara III. In comparison to the conventional technique, immature oil palms underplanting required more insertion plants, displayed etiolation symptoms, and had a lower average bunch weight. When using underplanting techniques for oil palm replanting, it is necessary to be disciplined in the application of Best Agronomic Practices in all stages of plant maintenance.
