Abstract

Physical damage to the fruit affects the quality of Crude Palm Oil (CPO) of palm oil. Gibberellin (GA3) is known as a growth hormone that is able to extend cells and is widely usedin maintaining the shelf life of several types of fruits. This study aims to study the effect of gibberellin dosage, the effect of gibberellin application on the physical quality of oil palm freshfruit bunches. The research was carried out at the North Julok Rayeuk Garden, PT. Perkebunan Nusantara I. The research period was 10 days, in March 2021. This study used a non-factorial Randomized Block Design (RAK) method and 6 replications with a total of 2 samples and a total sample of 48 samples. Parameter testing is compiled on a list of variances and statistical analysis is carried out which tests the average difference with Analysis of Variance (ANOVA) then further tests are carried out using Duncan's Multiple Range Test (DMRT) at 5% level. The results showed that the treatment dose of Gibberellin G1 (15 ml/L water) had a significant effect on reducing fruit loss and had no significant effecton the value of freefatty acids. Keywords: Elaeis guineensis Jacq,Gibberellins(GA3),physical quality

Abstract

This study was conducted to determine the effect of the application of liquid organic fertilizer in cow urine on the vegetative growth of oil palm seedlings in early nurseries. This research was conducted in the experimental garden of ITSI Medan. This research was conducted for 3 months. Starting from August 2021–October 2021. This study used a non-factorial Randomized Block Design (RAK) method consisting of 5treatments with 5 replications, so the number of samples was 25 seeds. Parameters observed were plant height, stem diameter, number of leaves, shoot dry weight, root dry weight, shoot wet weight and root wet weight. The data obtained were statistically analyzed by DMRT and ANOVA tests. The results of this study indicate that the application of liquid organic fertilizer cow urine has an effect on the vegetative growth of oil palm seedlings in early nurseries with the best dose of 20 ml cow urine. The standard gave some significant and very significant effects on stem height, stem diameter, number of leaves, but had no effect on wet weight and dry weight. Keywords:urine, pre nursery, poc

Abstract

This research was conducted to determine the response of the growth of oil palm seedlings (Elaeis guineensis Jacq) with solid application as analternative planting medium in the main nursery. This research was conducted at the Agricultural High School Gardens and the Agricultural Agribusiness Laboratory (STIP-AP) Medan. This research was conducted from April to August 2019. This study used a non factorial randomized block design (RBD) with 4 replications, with a total sample of 48 samples. The parameters observed were plant height, stem diameter, leaf blade, number of roots, primary root length, root wet weight, crown wet weight, root dry weight and crown dry weight. The data obtained were statistically analyzed by analysis of variance (ANOVA). The results of this study indicate that the application of solid waste as analternative planting medium for oil palm nurseries (Elaeis guineensis Jacq) in the main nurseries has a significant effect on several parameters observed including stem diameter, number of leaves, and root dry weight. Keywords: decanter solid, seedlings, simalungun DxP varieties, palm oil, alternative

Abstract

Palm oil midrib can also be used as a base for composting. Palm fronds which have been underutilized by the community and are more wasteful are usually only stacked around the tree. One way to use oil palm leaf fronds as a source of plant nutrients is in the form of compost. Palm oil fronds contain high lignin, so the process of composting oil palm fronds takes a long time. The process of decomposition of oil palm fronds naturally takes a long time which is around 3-4 months. This study will analyze the feasibility of utilizing corn meal as a compost material for oil palm fronds, corn meal is used as an energy source for microorganisms to accelerate the decomposition of oil palm fronds.This research was conducted in the greenhouse of the Agricultural Agribusiness College of Agriculture (STIPAP) Medan. When the research was conducted for 3 months, from March to May 2019. Palm oil fronds composting is 50 kilograms with a production cost of Rp 1,121,308 and a total income of Rp 1,200,000. The net profit of making oil palm frond compost is Rp. 78,692. BEB the price of making palm oil compost is Rp. 22,426 while the selling price of compost is Rp. 24,000. The BEP of producing oil palm fronds compost obtained is 47 kilograms while the amount of production of oil palm frond compost making is 50 kilograms so it can be interpreted that BEP production of oil palm frond composting is profitable because the amount of production of BEP production is greater. R / C ratio, which is the ratio of total receipts with total production costs has an R / C value of 1.07, then the R / C value can be greater than 1, it can be interpreted that the R / C value of making compost makes a profit. B / C ratio, which is the ratio of profits to total production costs has a B / C value of 0.07, thus the B / C value is smaller than 1. Then it can be interpreted that the B / C value of making compost does not benefit or is not feasible to run in the production of 50 kilograms. Keywords: palm fronds, compost, corn meal, break event point

Abstract

Ultisol soil is soil with soil acidity problems, little organic material and low macro nutrients, so it has a big impact on the productivity of oil palm plants. Organic matter is one of the limiting factors and plays a very important role in nutrient delivery and as a nutrient buffer. This research was carried out at PT. Langkat Nusantara Kepong Kebun Tanjung Beringin Langkat Regency in Division 2 Immature Crops (TBM) and Mature Crops ™. From December 2023 to February 5 2024. This research aims to be able to determine the soil organic matter content in the Immature Plants (TBM) and Mature Plants ™ phases in ultisol soil in the oil palm plantations of PT. Langkat Nusantara Kepong Kebun Tanjung Beringin. This research used quantitative descriptive methods and a completely randomized design. Research Results: The organic C content of Tanjung Beringin gardens is relatively low. The C-organic content in the TBM area has a significant difference compared to the TM area. The N content of Tanjung Beringin garden soil is classified as very low and there is no significant difference between the TBM and TM areas. Keywords: ultisol soil, organic matter, palm oil, TBM, TM
