Abstract

Eco reefer container adalah container pendingin yang terintegrasi dengan kemampuan control temperature. Reefer container digunakan untuk mengirim produk yang sensitif terhadap perubahan temperature misalnya buah, sayuran, daging, ikan, bunga, obat-obatan dan bahan kimia. Peti kemas berpendingin menggunakan listrik sebagai sumber daya, dan menggunakan bahan berlapis untuk menjaga container dari perubahan temperature yang disebabkan faktor eksternal maupun internal. Perubahan temperature pada reefer container membutuhkan sumber daya yang besar sehingga perlu di monitoring untuk mengetahui besar energi yang dipergunakan. Pada tugas akhir ini menggunakan sistem pendingiin sebagai prototype pengganti dari ERC karena memiliki kesamaan prinsip dan fungsi kerja. Menggunakan mikrokontroler ESP32 untuk mengirim data dan sensor power meter untuk melakukan pengukuran energi listrik pada sistem pendingin atau kulkas. Dilengkapi dengan monitoring 4 sensor temperature 4 yang sangat diperlukan untuk mengetahui berapa jumlah daya yang dikeluarkan untuk mendinginkan suatu produk. Pada monitoring energi listrik terdapat tampilan berupa nilai tegangan, arus, daya, kWh dan biaya dalam satuan rupiah. Hasil pembacaan power meter akan dikirimkan melalui komunikasi modbus agar bisa diakses secara online atau berbasis IoT (Internert of Things). Pada hasil validasi sensor power meter, pembacaan nilai arus memiliki nilai presentase error sebesar 2,47% dengan akurasi sebesar 97,53%. Untuk hasil validasi nilai tegangan memiliki presentase error sebesar 0,247% dan akurasi sebesar 99,753%. Berdasarkan hasil percobaan kulkas terisi beban dan tidak, didapatkan hasil berupa nilai daya berkisar antara 0.12 dan 0.13 watt untuk beban kulkas terisi ¼ dan ½. Sedangkan untuk beban terisi ¾ menghasilkan daya sebesar 0.14 sampai 0.16 watt, dan ketika keadaa kulkas terisi penuh akan menghasilkan daya sebesar 0.13 sampai 0.15 watt

Eco reefer container is a cooling container that is integrated with temperature control capabilities. Reefer containers are used to transport products that are sensitive to temperature changes such as fruit, vegetables, meat, fish, flowers, pharmaceuticals and chemicals. Refrigerated containers use electricity as a power source, and use layered materials to protect the container from changes in temperature caused by external and internal factors. Changes in temperature in the reefer container require large resources so it needs to be monitored to determine the amount of energy used. This final project uses a cooling system as a replacement prototype for ERC because it has the same principles and work functions. Using the ESP32 microcontroller to send data and a power meter sensor to measure electrical energy in the cooling system or refrigerator. Equipped with monitoring 4 temperature sensors 4 which are very necessary to find out how much power is released to cool a product. In monitoring electrical energy there is a display in the form of the value of voltage, current, power, kWh and costs in rupiah units. The power meter reading results will be sent via modbus communication so that they can be accessed online or based on IoT (Internet of Things). In the validation results of the power meter sensor, the reading of the current value has an error percentage value of 2.47% with an accuracy of 97.53%. For the validation results, the voltage value has an error percentage of 0.247% and an accuracy of 99.753%. Based on the experimental results of the refrigerator being loaded and not being loaded, the results obtained were power values ranging between 0.12 and 0.13 watt for the refrigerator load being ¼ and ½ filled. Whereas for a ¾ full load it produces a power of 0.14 to 0.16 watt, and when the refrigerator is fully charged it will produce a power of 0.13 to 0.15 watt.
