Karakterisasi Fisiko Kimia Pliek U Khas Aceh pada Tahap Akhir Fermentasi

Wed, 23 Oct 2024 00:00:00 +0700

Pliek U is a traditional fermented product from Aceh, is derived from coconut fermentation, producing a distinctive aroma and taste. This study aims to analyze the chemical characteristics of Pliek U during the fermentation process, focusing on moisture content, pH value, and water activity (aw). The data reveal that these chemical parameters are significantly influenced by the type of raw material, fermentation duration, number of pressings, and treatment methods. The moisture content of the samples ranged from 48% to 51.3%, with semi-mature coconuts exhibiting the highest moisture content compared to mature or mixed coconuts. More frequent pressing of semi-mature coconuts did not entirely eliminate water content, as the softer structure of semi-mature coconut flesh tends to retain more moisture. Additionally, microbial activity during fermentation affects the moisture content by producing metabolites such as gases and water. The pH value remained stable at 5.6 across all samples, reflecting the optimal activity of lactic acid bacteria (LAB) during fermentation. This stability indicates a well-controlled fermentation process, resulting in a safe and high-quality product. LAB plays a crucial role in producing organic acids that not only regulate pH but also contribute to the distinctive taste of Pliek U. The water activity (aw) of Pliek U ranged from 0.80 to 0.82, supporting the microbiological stability and shelf life of the product. Low aw values limit the growth of pathogenic and spoilage microorganisms, thus extending the product’s durability. However, excessively low aw values can affect texture, making the product harder and drier. Therefore, controlling aw is essential to maintain the product’s texture, taste, and microbiological stability

Drip irrigation system is one of the methods of water use that is done as a way of improving technology to increase crop production. Drip irrigation system is one of the systems applied to tomato plants, which this system has not been widely used so its feasibility needs to be analyzed. This study aims to (1) determine the amount of costs, revenues, and income of tomato farming with drip irrigation system in urban farming activities (2) determine the feasibility of tomato farming using drip irrigation system in urban farming activities. This research was conducted at P4S Galih Jaya, Kahuripan Village, Tawang District, Tasikmalaya City. This research was conducted using a case study method. Data analysis was carried out using cost, revenue and profit analysis, as well as feasibility analysis which includes R/C Ratio. The results of the analysis obtained the total production costs incurred in carrying out tomato farming using drip irrigation system amounted to Rp. 5.769.820, the income obtained from tomato farming using drip irrigation system amounted to Rp. 7,268,700, while the income received was Rp. 1.498.880. The R/C Ratio value in tomato farming with a drip irrigation system is 1.26, this indicates that the R/C Ratio <1. This means that tomato farming with a drip irrigation system carried out by P4S Galih is profitable and feasible to run
