Abstract

Coffee is a leading plantation commodity as it serves as a source of income for farmers, provides raw materials for industries, creates job opportunities, and promotes regional development in Bener Meriah Regency. To achieve optimal production results, farmers must adequately manage and maintain their coffee plantations, one way being the reduction of chemical usage that may affect the coffee beans. The negative impact of excessive chemical use includes rejecting exports to several European countries due to residue levels exceeding the limits set by European Union regulations. Therefore, analyzing herbicide residues and studying the factors affecting their persistence is necessary. Sampling was conducted in five sub-districts: Gajah Putih, Bandar, Permata, Timang Gajah, and Bukit, by collecting soil and bean samples from five points in each sub-district for analysis using gas chromatography. The research showed glyphosate residue levels of 0.002 mg/kg in each soil and bean sample. These levels are considered low compared to the maximum residue limit (MRL) for coffee, which is 0.1 mg/kg. This indicates that glyphosate residue contamination in the sampled plots is considered safe for consumption. Observations and interviews with farmers concluded that the low residue levels in the soil samples were influenced by several factors, including climate (temperature, humidity, rainfall), soil characteristics, topography, herbicide characteristics, and weed types.

Abstract

Shallots (Allium ascalonicum L.) are one of the leading vegetable commodities in Indonesia that have many benefits, such as a flavouring for cooking spices, raw materials for the food industry, and traditional medicinal ingredients. Inceptisol is a soil with a low content of essential nutrients. However, it can still be pursued with the proper technological handling, one of which is the application of Liquid Compound Fertilizer (PMC). This study aims to determine the effectiveness of the liquid compound fertilizer (PMC) formula applied to Inceptisol soil on the growth and yield of shallot plants. This research was conducted at the Experimental Garden, Faculty of Agriculture, Malikussaleh University, from November to December 2023. This study used a single-factor Complete Randomized Design (RAL) with five replicates. PMC treatment consists of 5 levels, namely (K0) Control, (K1) PMC 25%, (K2) PMC 50%, (K3) PMC 75%, and (K4) PMC 100%. The results showed that applying PMC could increase the growth of shallots in the number of cloves and wet and dry crop weight with a PMC concentration of 50%. And PMC treatment of 75% can increase plant height. PMC treatment is 100% able to increase the number of leaves/plants. The application of PMC can affect the chemical properties of the soil, namely increasing the soil's pH value (H2O) by 0.84%, the soil organic by 1.5%, the total N by 2.73%, and the available P by 5.62%.

Abstract

Coffee plants are an essential commodity widely cultivated in Bener Meriah Regency, Aceh Province. This study aims to determine the composition of dominant weed types and weed structures in Arabica coffee plantations in Bener Meriah Regency through weed vegetation analysis. Weed vegetation analysis is carried out in two ways, namely quantitative and qualitative. The research was conducted from November 2023 to March 2024 in 5 sub-districts. Weed sampling was carried out on five location plots per sub-district by placing a square measuring 1 m x 1 m diagonally to analyze the number of weeds, the number of individuals, and abundance. The study's results found 2,408 individuals and 35 species of weeds, namely 28 species of broadleaf weeds, three species of puzzles, three species of grasses, and one species of ferns. Spilanthes paniculata Wall weed. Ex DC or jotang is the most dominant weed, with an absolute density value of 392 (SDR 11.82). The absolute frequency value is dominated by Oxalis debilis or calincing. Meanwhile, the highest absolute dry weight was weeded S. paniculata Wall. Ex DC and A. conyzoides with values of 923.3 and 836.2. The life cycle of weeds showed that eight species (22.85%) had annual life cycles, and 27 species (77.15%) had annual life cycles. Stratification is classified as class 3, with as many as 14 species. Sociability is classified as 4th degree as many as 13 species. All weeds are classified as vitality 1. Meanwhile, the periodicity is only nine weed species that do not have flowers, seeds, and fruits.
