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

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

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pemberian pupuk kompos sampah organik dan pupuk majemuk (NPK) terhadap pertumbuhan vegetatif tanaman dan serapan hara N tanaman pada pembibitan utama kelapa sawit. Penelitian ini dilaksanakan di areal Pembibitan Sekolah Tinggi Ilmu Pertanian Agrobisnis Perkebunan Medan dan Laboratorium Sentral Fakultas Pertanian Univeristas Sumatera Utara pada bulan Desember 2019 sampai Juli 2020. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 2 Faktor yaitu Faktor 1 yaitu  Kompos Organik Sampah Pasar dan Faktor 2 yaitu Pupuk Majemuk (NPK) 16:16:16 dengan ulangan 3x dengan jumlah tanaman per plot 2 tanaman, jumlah polybag keseluruhan adalah 54 polybag. Pengujian parameter disusun daftar Sidik Ragam atau Uji Analysis of Variance (ANOVA) dengan taraf 5% dan 1% dan dialnjutkan dengan Uji Duncan’s Multiple Range Test (DMRT) pada taraf 5%. Hasil menunjukkan bahwa perlakuan kompos organik sampah pasar dan pupuk majemuk berpengaruh nyata terhadap parameter yang diamati yaitu tinggi bibit (cm), jumlah daun (helai), berat basah akar (gr), berat kering akar (cm), berat basah tajuk (gr), berat kering tajuk (gr). Namun tidak berpengaruh nyata terhadap Lingkar batang (cm) dan serapan hara N (%).

Abstract

MONANG ANTONIUS PURBA. 2020. THE EFFECT OF GOAT DIRTY ON THE VEGETATIVE GROWTH OF OIL PALM BIBT (Elaeis guineensis jacq) IN PRE NURSERY USING HYDROPONIC METHOD. Final Project of STIPAP Student of Plantation Cultivation Program. This research was supervised by Mr. Aulia Juannda Djs, S.Si., M.Si and Mrs. Ingrid Ovie. Y. Sitompul. This research was conducted in the STIPAP MEDAN greenhouse. When this research was conducted in April - July 2020. This study used the Hydroponic Method and used a completely randomized design as data processing. This research was conducted to determine the development of oil palm seedlings every 2 weeks. The vegetative growth of oil palm (Elaeis guineensis Jacq) in the pre-nursery using the hydroponic method using goat manure has no significant effect on most of the parameters observed except for plant height which has a significant effect. From the average observation of the effect of goat manure on the vegetative growth of oil palm seedlings (Elaeis guineensis Jacq) in the pre-nursery using the hydroponic method, it can be seen that the highest effect obtained is on the 2500ppm treatment, namely on plant height (19.85 cm), stem girth. (2.63 cm), and the number of leaves (3.31 cm). Meanwhile, the average yield of leaf chlorophyll and leaf width obtained the best results from the 1500ppm treatment, namely 24.99 cm stem girth and 3.39 cm leaf width. The conclusion that can be drawn from the results of this study is that the dose at the 2500ppm treatment is right for use in the hydroponic method and it is hoped that this research can be developed by looking for other organic fertilizers to be combined with goat manure with the best dose, so that the nutrient content that has been added is more complete. there is. And continued research was carried out at the Main Nursery (MN).
