Abstract

This study investigated the effect of the coffee drying process using a coffee drying house on the moisture content, acidity, caffeine value, and flavour of Arabica coffee. An experimental method with a two-factor analysis of variance was used to evaluate significant differences between three different drying processes: Before Drying Process, Sun Drying Process, and Drying Process with Coffee Drying House. The results showed that sun-drying coffee with a coffee drying house produced lower moisture content, acidity, and caffeine value than the other drying processes. The flavour of Arabica coffee produced by this method was also considered sweeter by coffee export standards. Statistical analysis with Anova Block Subsampling, Anova 1 Factor Fixed Model, and Anova 2 Factor Factorial Design showed that the coffee drying process using coffee drying houses significantly affects the quality of arabica coffee. This study concludes that coffee drying houses can be an effective solution in improving the quality of Arabica coffee by controlling the moisture content, acidity, and caffeine value. The results of this study contribute to understanding the process of drying coffee beans and the factors that affect the final quality of the product. Therefore, this study provides an essential scientific basis for coffee farmers and the coffee processing industry to improve the quality of their coffee.

Abstract

Purpose: This study investigated the effect of the coffee drying process using a coffee drying house on the moisture content, acidity, caffeine value, and flavor of arabica coffee. Design/methodology/approach: An experimental method with a two-factor analysis of variance was used to evaluate significant differences between three different drying processes: Before Drying Process, Sun Drying Process, and Drying Process with Coffee Drying House Findings: The results showed that sun-drying coffee with a coffee drying house produced coffee with lower moisture content, acidity, and caffeine value compared to the other drying processes Research limitations/implications: The research location was Karot Village, Langke Rembong Subdistrict, Manggarai Regency. The object of research was the drying process of arabica coffee beans and the measurement of moisture content, acidity content and caffeine content of arabica coffee. The method used was analysis of variance with a fixed model (one-way anava design, block subsampling anava and two-factor anava). The data obtained were the acidity value, caffeine value, moisture content and coffee flavour. Practical implications: The results of the research were successful and improved the quality of coffee exports in Karot Village, Langke Rembong District, Manggarai Regency. Originality/value: The research carried out by the researcher states that this research is the result of his work and is the first time at Karot Village, Langke Rembong District, Manggarai Regency with the title of the research being researched, except for quotations from several summaries, all of which the researcher has explained the source.

Abstract

Carrier vessels play a crucial role in the capture fisheries industry, particularly as transportation modes responsible for delivering harvested products from fishing grounds to the shore or port. This strategic function requires the implementation of clear Standard Operating Procedures (SOPs) to ensure that handling practices comply with regulations and meet quality standards. Therefore, assessing the application of SOPs on squid carrier vessels is essential to determine the extent to which existing procedures align with proper handling standards and regulatory requirements. The objective of this study is to evaluate the conformity of SOP implementation on squid carrier vessels with applicable regulations, identify weaknesses or inconsistencies in operational practices, and provide recommendations for improvements that may enhance product quality, operational efficiency, and the sustainability of fisheries enterprises. This research was conducted from March to May 2025, using KM Perintis Jaya 89 as the research object, a squid carrier vessel owned by Perintis Jaya International operating in Benoa, Bali. Data collection was carried out through direct observation during the vessel’s operational trips, including documentation of the number of trips, travel duration, cargo volume, and fuel consumption. The main focus of the assessment was the handling of squid, encompassing loading, storage, and unloading activities carried out by the carrier vessel. The findings indicate that KM Perintis Jaya 89 has implemented SOPs in accordance with policy directives. Proper and consistent SOP implementation supports effective and efficient vessel operations, thereby ensuring the maintained quality of squid products destined for market distribution.
