Internet of Things on Electrical Energy Monitoring Using Multi-Electrical Parameter Sensors

This study aims to apply the Internet of Things to monitoring electricity energy consumption. The system is designed to replace the manual and conventional measurement of electrical energy. Uncontrolled use of electricity is one of the causes of high levels of electrical energy consumption. Therefore, consumers need to know the amount of electrical energy consumption in real-time. The device is designed using the PZEM-004T which is used as a sensor to read electrical multi-parameter, Arduino as the main control, and ESP8266 as a data sender on the Cloud system. The test results showed that the device has been able to read and display electricity quantity data in the form of voltage, current, power, and electricity tariff accumulation in real-time displayed on the ThingSpeak platform. The test on the PZEM-004T sensor has an accuracy rate of 94.96% for reading current values and 99.42% for reading voltage values. Penelitian ini bertujuan untuk menerapkan teknologi Internet of Things pada monitoring konsumsi energi listrik. Sistem dirancang untuk menggantikan pengukuran energi listrik yang masih manual dan konvensional. Penggunaan listrik yang tidak terkontrol merupakan salah satu penyebab tingginya tingkat pemakaian energi listrik. Oleh karena itu, konsumen perlu mengetahui jumlah pemakaian energi listrik secara realtime. Alat dirancang menggunakan PZEM-004T yang digunakan sebagai sensor untuk membaca multi-parameter listrik, Arduino sebagai kendali utama, dan ESP8266 sebagai pengirim data pada sistem Cloud. Hasil pengujian menunjukan bahwa alat telah mampu membaca dan menampilkan data besaran listrik berupa tegangan, arus, daya, dan akumulasi tarif listrik secara realtime yang ditampilkan pada platform ThingSpeak. Pengujian pada sensor PZEM-004T memiliki tingkat akurasi 94.96% untuk pembacaan nilai arus dan 99. 42% untuk pembacaan nilai tegangan.

STUDI PEMAKAIAN DAYA SOLAR CELL-HYBRID OFF GRID GEDUNG LABORATORIUM ENERGI SURYA-JURUSAN TEKNIK KONVERSI ENERGI-POLBAN

Solar energy is a renewable source that has never been exhausted, this energy will not reveal pollution into environment such as another power plant. Solar Power Plant is one of renewable source that become on alternative source in the future. One of application of this system is Hybrid Solar Power Plant, this power plant it is use to accomplish electricity energy consumption in Solar Laboratory Energy Conversion Engineering POLBAN with benefitted solar energy as electricity energy soarce. Electricity of energy there is resulted dependent on high and low solar light intensity. This paper is analyzed for both of supply and demand electricity in Laboratory of Solar Energy - Energy Conservation Engineering Department-POLBAN.

Household Characteristics That Influence Simple Household Demand on Electricity

This research aims to analyze the characteristics of households that affect the electric energy consumption of simple households. The second objective is to analyze the probability of each of the factors affecting the electricity energy consumption of small household. The research was conducted in Medan City in the period of March 2014 to November 2014 with samples of 143 small households, the customer of PT. PLN (Persero) Medan, which use the power of electricity for TR-1 /450VA. Data were analyzed by using the logistic regression model. The estimation results indicated that (1) the higher the willingnes to pay (WTP) of households, the higher the tendency to consume elec trical energy per month. (2) the closer the households residence to the city center, the higher the tendency to consume electrical energy than of the households residence in the suburbs, (3) increasingly unfavourable response to electrical quality, the higher the opportunity to consume a greater electric power monthly.
