Abstract

Electricity is a basic need of human beings. The consumption of electricity usage is getting bigger and bigger. Electricity usage is usually wasteful due to lack of public awareness and ineffective use of electricity. With this problem, the author aims to design loT-based electric power usage monitoring system in home electrical appliances. This tool is designed using sensors to detect the value of the voltage and current of the load attached to the electricity but still using the BLYNK application as a server and application to monitor the use of electric power through a smartphone application. The measurement results include the data of current, voltage, and electrical power used. This system can also remotely switch appliances ON/OFF. The test was conducted by comparing the results of the power value from the power meter with the power value in BLYNK application. After the test, the results of the comparison between the monitoring tool and the power meter measuring instrument obtained an average power error value of 0.5%. So that the accuracy value of the tool can also be 99.5%. With a large accuracy value, it means that the tool works well and can be used to monitor the use of electrical energy in households.

Abstract

Indonesia merupakan salah satu negara dengan penggemar sepak bola terbanyak nomor 2 di dunia. umumnya pertandingan sepak bola di Indonesia dilaksanakan pada siang hari namun, pertandingan sepak bola dapat dilaksanakan pada malam hari. Pencahayaan (iluminasi) adalah kepadatan berkas cahaya yang menerangi suatu permukaan. Pencahayaan dapat didefinisikan sebagai jumlah dari cahaya yang jatuh pada sebuah bidang objek permukaan. Pencahayaan terdiri atas pencahayaan alami dan pencahayaan buatan. Lapangan sepak bola Universitas Malikussaleh merupakan lapangan utama atau lapangan inti dari kampus. Pengamatan yang telah dilakukan pada lapangan sepak bola Universitas Malikussaleh diketahui bahwa sistem pencahayaan pada lapangan sepak bola Universitas Malikussaleh sudah tidak beroperasi. Metodologi pada penelitian ini berupa eksperimen, yaitu dengan cara melakukan pemodelan kembali sistem pencahayaan buatan lapangan sepak bola Universitas Malikussaleh dengan software DIALux. Lampu yang digunakan yaitu, Philips ArenaVision MVF-403 MHN-LA1000W/230V/956 A1 dan lampu Panasonic NYS12837LF2031 LED Light Stadium. Simulasi redesain sistem pencahayaan buatan lapangan sepak bola Universitas Malikussaleh dilakukan dengan menggunakan software DIALux. Hasil yang diperoleh dari penelitian ini yaitu, konsumsi energi listrik lampu Philips ArenaVision MVF403 MHN-LA1000W/230V/956 A1 dalam sekali pertandingan sebesar 90,56 KWh dan total lumen yang dihasilkan sebesar 5.040.000 lumen. Untuk lampu Panasonic NYS12837LF2031 LED Light Stadium sebesar 57,82 KWh dalam sekali pertandingan. dan lumen lampu yang dihasilkan sebesar 5.760.000 lumen. berdasarkan hasil simulasi, kedua jenis lampu yang digunakan sudah sesuai dengan SNI 03-3647-1994, untuk lapangan pertandingan dibutuhkan minimal 300 lux.

Abstract

The need for internet connection is very important because everything is connected to each other with the internet, but due to limitations on access points, many areas are still experiencing difficulties in accessing the internet, one of which is the suburban area. Suburban areas that are indicated to be still difficult to reach due to obstacles from buildings, and the influence of weather. In order for the signal to be reached in this area, an 11-element yagi antenna with a working frequency of 1800 MHz is needed which is expected to produce a high gain so that the antenna beam is maximised. This final project aims to design an 11-element Yagi antenna at a working frequency of 1800 MHz, and analyse antenna parameters such as return loss, VSWR, bandwidth, gain, and polaradiation. Where the design of the yagi antenna uses CST Studio Suite 2019 software. After the simulation results are as desired, then fabrication or manufacture of the antenna is carried out. The simulation results after optimising are -26.00 dB, VSWR 1.10, and gain 12.32 dB. After the simulation is carried out, the next fabrication or manufacture of the 11-element Yagi antenna, the measurement obtains a return loss value of -11.29 dB, and VSWR 1.74, although the measurement results are far from the simulation but the results of this measurement have met the requirements of the antenna specifications.
