Abstract

Budidaya perikanan berperan penting dalam memperkuat ketahanan pangan nasional. Namun, tantangan seperti pengelolaan jadwal pemberian pakan yang teratur dan efisien masih dihadapi oleh pelaku budidaya ikan di Aceh. Dalam konteks ini, sebuah solusi diusulkan melalui perancangan mesin pemberi pakan otomatis berbasis IoT. Mesin ini memungkinkan pengawasan dan pengaturan jarak jauh terhadap pemberian pakan, yang tidak hanya mengurangi intervensi manusia tetapi juga membantu meminimalkan pemborosan pakan dan memastikan pemberian pakan yang tepat waktu. Dengan tambahan panel surya, mesin ini mampu menghasilkan energi sendiri, mendukung pemanfaatan energi terbarukan. Solusi ini memanfaatkan model manufaktur efisien dan mampu mengatasi kendala pertumbuhan ikan yang terganggu akibat pengelolaan pakan yang tidak teratur. Selain manfaat langsung bagi hasil panen ikan, produk ini juga dapat meningkatkan pendapatan nelayan mitra. Melalui langkah-langkah seperti pengajuan hak kekayaan intelektual dan pemantauan oleh tim pengusul, diharapkan produk ini dapat berkontribusi pada ketahanan pangan dan berkelanjutan di Aceh.

Abstract

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 124.72 W 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 127.96 W. 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

Abstract

An internal combustion engine converts thermal energy into mechanical work with an efficiency of approximately 35–40%, depending on the engine type and operating conditions. This indicates that about 60–65% of the total energy is wasted, primarily in the form of heat loss through the cooling system, exhaust gases, and mechanical friction. One potential approach to improve engine efficiency is by recovering waste heat using a thermoelectric generator (TEG) system. This study aims to analyze the exergy performance of a thermoelectric heat recovery system that utilizes exhaust gas heat from an internal combustion engine as an energy source. The analysis focuses on the influence of engine speed variation and aluminum fin configuration on the exergy value, exergy destruction, and exergy efficiency to enhance waste heat utilization. The heat recovery system is connected to the exhaust pipe outlet, and several fin configurations are investigated: left–left-right, top–bottom, all-sided, and without fins. Tests were conducted at engine speeds of 1300, 1600, 1900, and 2200 rpm to observe variations in energy distribution and efficiency. The results indicate that the exergy value generated by the thermoelectric heat recovery system increases with higher engine speed. This finding demonstrates that the proposed system can effectively improve the thermal efficiency of internal combustion engines by converting exhaust heat into useful energy, contributing to overall energy savings and the development of more efficient energy conversion technologies.
