Abstract

Pemborosan dalam penggunaan energi listrik kini tampaknya telah menjadi kebiasaan. Seperti dalam pemakaian lampu jalan yang tetap menyala meski dalam keadaan yang tidak memerlukan penerangan menjadi salah satu kebiasaan tersebut. Dengan kebutuhan akan energi listrik yang terus meningkat, salah satu solusinya yaitu menerapkan sistem otomatis pada penerangan jalan dengan menggunakan sensor Light Dependent Resistor (LDR) dan sensor Passive Infrared Receiver (PIR) yang bertujuan agar pemakaian energi listrik dapat lebih efesien. Dalam jurnal ini penulis ingin membuat rancang bangun penerangan jalan raya berbasis arduino uno. Secara umum prinsip kerja dari alat ini adalah lampu penerangan jalan akan otomatis menyala dengan cahaya redup saat keadaan mulai gelap dengan menggunakan sensor LDR. Lampu juga akan otomatis menyala terang apabila sensor (LDR dan PIR) berhasil mendeteksi sehingga akan menampilkan informasi pada tampilan LCD. Dan jika sensor (LDR dan PIR) tidak mendeteksi apapun lampu jalan akan kembali meredup sehingga dapat menghemat pemakaian energi listrik. Hasil dari rancang bangun ini telah bekerja sesuai dengan yang direncanakan yaitu menghidupkan lampu secara otomatis menggunakan sensor Light Dependent Resistor (LDR) dan sensor Passive Infrared Receiver (PIR). Dan menampilkan informasi pada layar LCD.

Abstract

Penggunaan lampu jalan merupakan salah satu konsumsi energi yang besar dan masih belum efisien dalam penggunaannya. Untuk itu diperlukan sebuah sistem yang dapat mengontrol dan mengendalikan penggunaan energi pada lampu jalan agar penggunaan energi listrik menjadi lebih efisien. Pada penelitian ini, sistem yang dibangun adalah untuk mengendalikan penggunaan energi listrik pada lampu jalan menggunakan mikrokontroler Arduino Uno dengan memanfaatkan LDR (Light Dependent Resistor) dan PIR (Passive Infrared Receiver) sebagai sensor cahaya dan sebuah LCD untuk menampilkan jumlah kendaraan dan orang yang terdeteksi. Lampu jalan dirancang memiliki pencahayaan maksimal pada saat ada kendaraan atau pejalan kaki yang lewat dan akan redup jika sensor tidak ada mendeteksi pergerakan baik kendaraan atau orang yang lewat. Dari pengujian yang dilakukan, sistem dapat bekerja dengan baik sesuai dengan algoritma kerja yang dirancang.

Abstract

Internet of thing (IoT) is a system that will change the order of human life and industrial operations. In the future, objects that are operated daily with human interaction will be equipped with internet connectivity which is equipped with various sensors so that they are able to communicate and act on the information obtained without human intervention. The problem is that the ecosystem has not been fully developed as well as from the world of education which will prepare its human resources. Apart from that, the industrial sector which is predicted to be the largest user is still considering various things such as cost, security, non-conformity with the existing system and the ability of its resources. The system created is an effort to develop knowledge in the IoT field as an effort to bridge the need for human resources, especially at the Vocational High School (SMK) level. This IoT application for electrical load control is designed and built using the main components of NodeMcu V3, 4 channel relay, and Android with the Blynk application installed. Electrical load control commands are given using the Blynk application via Android and delivered to the NodeMcu V3 module using a Wifi intermediary and from NodeMcu V3 forwarded to 4 channel relays to control electrical loads in the form of ON and OFF. The results of the test show that the system built can operate properly in controlling electrical loads

Abstract

This paper discusses the use of buck converter for battery charging using solar power sources. The nominal voltage of the battery used is 12 Volt and the output voltage of the solar panel without load is 22.68 Volts. Buck converter is used to reduce the output voltage of the solar panel and to control the stability of the output voltage is used Atmega 8 microcontroller. From the test results, the buck converter output voltage is stable at a value of 14.4 volts even though the input voltage is changed. Apart from that, the duration of battery charging is very much determined by weather changes that affect the ability of solar panels to produce energy for battery charging

Abstract

This article aim to be able to take advantage of an electric motor as a net puller on a fishing boat using solar energy. The use of human labor as a net puller requires a large amount of energy and needs a break to be able to do more withdrawal activities, so the number of withdrawals that can be done is very limited. Pantai Jaya fishing groups as partners are among the 20 active fishing groups in the Pasie Nan Tigo sub-district of Koto Tangah subdistrict of Padang City who experience these problems. The problem of this partner can be given a solution in the form of the use of an electric motor as a towing net on a fishing boat. In order not to cause problems in terms of electricity supply, solar energy can be used by using solar cells, so there is no addition of fuel oil. The implementation method given is direct installation and provision of extension materials on the use of solar cell technology and the introduction of components and hand tools. This activity was carried out for two days which included preparation, installation and training, followed by a group of fishermen. The fishing group received a set of solar cells, electric motors, batteries and other accessories and installed them. Based on tests that have been carried out in sunny weather conditions at 300C, a load of 50 kg with a rated voltage at that time 12.4V, motor speed 2.7m / min, 2.4A. Based on the results of these tests indicate that the solar cell system has worked according to the parameters it should. Therefore, it can be said that this activity has been carried out properly and the solar cell system is functioning properly. Participants hope for these activities to be carried out for the following year, because there are still a number of fishing boat groups that are in dire need.

Abstract

Abstract— This paper discusses multilevel single-phase inverters to improve voltage quality by reducing harmonics. In order to see the performance of multilevel single-phase inverters in reducing the output voltage harmonics, a comparison of several single-phase multilevel inverters with a multilevel H-bridge topology is performed. Increasing the voltage level on the multilevel inverter will reduce harmonics such that losses will be significantly reduced. Multilevel single phase inverter simulation is performed for three-level, five-level and seven-level inverters using matlab/simulink software. The simulation results show that the Total Harmonic Distortion (THD) output voltage of five levels single phase inverter is smaller than three-level inverter and THD output voltage of the seven levels inverter is smaller than using a five-level single phase and three-level inverter, where the THD can be reduced to 13 45%. Index Terms— multilevel single phase inverter, harmonics, THD.  Abstrak–- Tulisan ini membahas tentang multilevel inverter satu fasa untuk memperbaiki  kualitas tegangan dengan mengurangi harmonisa.  Untuk melihat kinerja multilevel inverter satu fasa dalam mereduksi harmonisa tegangan keluaran dilakukan perbandingan beberapa multilevel inverter satu fasa dengan topologi jembatan-H bertingkat. Peningkatan level tegangan pada multilevel  inverter akan mengurangi harmonisa akibatnya rugi-rugi akan berkurang secara signifikan. Simulasi multilevel inverter satu fasa dilakukan untuk inverter tiga tingkat, limatingkat dan tujuh tingkat menggunkana software matlab/simulink. Hasil simulasi memperlihatkan Total Harmonic Distortion (THD) tegangan keluaran inverter satu fasa lima tingkat lebih kecil dibandingkan dengan inverter tiga tingkat dan THD tegangan keluaran inverter tujuh tingkat  lebih kecil dibandingkan menggunakan inverter satu fasa lima tingkat dan tiga tingkat, dimana THD nya dapat direduksi menjadi 13,45%. Kata Kunci— multilevel inverter satu fasa, harmonisa, THD.
