Abstract:Ikan merupakan salah satu sumber protein yang baik bagi manusia, hanya saja daging ikan tersebut mudah menurun kualitasnya, untuk mempertahankan kualitas daging ikan perlu di dinginkan. Salah satu alat yang di gunakan untuk mendinginkan ikan adalah menggunakan mesin pendingin. Mesin pendingin merupakan mesin yang kompleks, terdiri dari beberapa komponen dan dalam pengoperasinya harus tepat, kekeliruan dalam pengoperasian akan mengakibatkan kegagalan operasional mesin yang berdampak pada kerugian. tujuan peneli… Show more
“…Research conducted by [11] explained that the analysis of the cooling load of cold storage for meat storage using the experimental method obtained an external cooling load of 11.6 kW, an internal cooling load of 138.8 kW and a COP of 2 while research conducted by [12] stated that it requires a voltage of 380 kV and the valve must be opened so that cold storage can circulate. The test results by [13] show that the ALREF system can be used as cold storage at -18°C, which allows it to be used as an alternative for fish storage which is not suitable for seawater cooling.…”
Data from the Ministry of Maritime Affairs and Fisheries shows that Aceh Province, with a coastline length of 2666.3 km stretching from east to west, holds a variety of marine wealth, both fisheries and other natural resources. The province of Aceh has archipelagoes spread over Aceh Besar and Aceh Singkil. The archipelago areas in Aceh Besar are Aceh Island, Rice Island and Nasi Island. The availability of electricity in the archipelago, namely on the island of Aceh, is only at 18.00 -22.00 and 5.00 -8.00. Because of this, a study was carried out on using solar electricity to drive compressors in cold storage. This study aims to determine the solar energy capacity and photovoltaic area required for cold storage with a capacity of 100 kg of fish, determine the temperature of the cold storage when operating with and without load and determine the Coefficient of Performance (COP) of cold solar storage over time. This research was conducted experimentally to test the use of cold storage for storing fish. The results showed that the cold storage temperature was -15.9 ℃ with an average current of 0.87 A, a voltage of 226.02 V and a power of 124.72W when operating without load, while with a load, the temperature was -3.1 ℃ with an average current is 0.890 A, voltage is 225.88 V, and power is 127.96W. The ideal COP value is greater than the actual COP value (8.07 <2.69). To run cold storage using solar energy, a battery with a capacity of 120 Ah is required until it reaches a temperature of -3.1 ℃ lasts 2 -3 days with 40% remaining battery usage and is recharged every day.

“…Fish is one of the important elements of fisheries which play a role in the processing of fishery products. In relation to the marine sector, fish is one of the most processed marine products in Indonesia, therefore optimizing marine fish food must be through correct processing [7][8]. Fishery products generally spoil more quickly than other products such as meat.…”

“…Cold storage is a way of storing fish at a certain temperature which allows fresh fish to be stored for a long period of time, even months, to prevent the growth of bacteria in the fish. The use of mechanical cooling in the fishing industry, the process of reducing product temperature is considered the most efficient compared to other methods so that cooling is needed to maintain fish quality [8,10]. Handling fresh fish requires correct procedures in accordance with predetermined standards.…”
Fishery products generally spoil more quickly than other animal meat products. After being caught, fish will experience changes in quality, the level of these changes will determine the shelf life of the fish. Handling fresh fish is the most important aspect of a fisheries business. Cold storage is a way of storing fish at a certain temperature which allows fresh fish to be stored for long periods, even months, to prevent bacterial growth. This research aims to evaluate the implementation of the Standard Operating Procedure (SOP) for storing fish in cold storage using the First In First Out (FIFO) system and to evaluate the quality of the cooling system using temperature and humidity monitoring at Jaya Bahari cold storage. The method used in this research is measurement, interviews and literature study. The process stages in receiving fish products start from unloading fish, thawing frozen fish, weighing and testing samples, sorting and calculating the percentage of rejects, as well as temporary storage by looking at various obstacles during the process of receiving raw materials. The performance of the data logger and big data each showed results that were not much different with the respective tool accuracy values of 99.26% for temperature measurements and 99.83% for humidity measurements. Defrosting ice for 2 hours can save power by 4.37%.
