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

Weeds are one of the major limiting factors in crop production because they compete with cultivated plants for water, light, nutrients, and growing space. Excessive use of chemical herbicides may lead to weed resistance and adverse environmental impacts, highlighting the need for more environmentally friendly weed control alternatives. This study was based on the theory of allelopathy, which explains the ability of allelochemical compounds to inhibit the growth of other plants. The objective of this research was to evaluate the potential of cogongrass rhizome (Imperata cylindrica) extract as a bioherbicide against Synedrella nodiflora. The experiment employed five extract concentrations, namely 0%, 10%, 20%, 30%, and 40%, applied repeatedly through foliar spraying. Data were collected by observing plant height, leaf number, leaf discoloration, and overall visual appearance of the weed. The results showed that increasing extract concentrations led to greater symptoms of chlorosis, necrosis, and wilting. The 40% concentration treatment produced the highest level of weed damage compared to the other treatments. Therefore, cogongrass rhizome extract has the potential to be used as an effective and sustainable natural bioherbicide for controlling Synedrella nodiflora.

Abstract

This study aims to analyze the effect of sunlight intensity and conidium density on the intensity of leaf rust disease caused by Phakopsora pachyrhizi in edamame plants grown in immature oil palm areas. The study used a quantitative descriptive approach by observing sunlight intensity, conidium density, and disease intensity. The data were analyzed using multiple linear regression with SPSS after log transformation of the disease intensity variable to meet the normality assumption. The Kolmogorov-Smirnov test showed an Asymp. Sig. value of 0.200, indicating that the data were normally distributed. The model also showed no multicollinearity, as indicated by a Tolerance value of 0.904 and a VIF of 1.106, and no heteroscedasticity pattern was found in the residual scatterplot. The regression produced the equation Y = 0.830 + 0.000000039X1 + 0.033X2. Sunlight intensity did not have a significant partial effect, whereas conidium density had a positive and significant effect on disease intensity. Simultaneously, both variables had a significant effect, with an F-statistic of 440.049 and an R Square value of 0.954.
