Abstract

Adanya jarak yang jauh dari pusat pembangkit ke beban pada sistem penyaluran tenaga listrik menyebabkan profil tegangan pada sisi terima atau sisi konsumen kadang turun kualitas tegangannya. Salah satu dari penurunan kualitas tegangan adalah penurunan level tegangan. Standar penurunan level tegangan pada setiap negara berbeda-beda tetapi secara umum penurunan level tegangan yang diijinkan kurang lebih tidak boleh lebih dari 10%. Tujuan penelitian ini adalah mengetahui pengaruh setting tap pada transformator untuk mengoptimalkan penurunan level tegangan pada sisi terima atau pada sisi konsumen. Dengan setting tap transformator diharapkan memperbaiki aliran daya dan profil tegangan pada masing-masing bus. Profil tegangan tidak hanya dipengaruhi oleh nilai setting tap transformator saja, tetapi bentuk dari jaringan juga berpengaruh. Hasil penelitian ini adalah dengan mengubah setting tap transformator dapat menghasilkan perubahan aliran daya dan profil tegangan. Setting tap yang paling optimal didapatkan pada nilai yang optimal, bukan nilai tap transformator yang semakin kecil atau semakin besar nilainya. Rata-rata penurunan level tegangan paling kecil diantara 3 skenario yang diterapkan didapatkan hasil yaitu rata-rata penurunan sebesar 5,137 % pada skenario dengan tap setting 0,95.  The long distance from the power plant to the load on the electric power distribution system causes the voltage profile on the receiving side or the consumer side to sometimes decrease the quality of the voltage. One of the decrease in the quality of the voltage is a drop voltage. The standard drop in voltage level varies from country to country but in general the allowable drop in voltage level should not be more than 10%. The purpose of this study was to determine the effect of setting tap on the transformer to optimize the voltage level drop on the receiving side or on the consumer side. By setting the tap transformer, it is expected to improve the power flow and voltage profile on each bus. The voltage profile is not only affected by the transformer tap setting value, but the shape of the network also has an effect. The result of this research is that changing the transformer tap settings can result in changes in the power flow and voltage profile. The most optimal tap setting is obtained at the optimal value, not the smaller the transformer tap value or the larger the value. The smallest average drop voltage level among the 3 scenarios applied, the results obtained are an average decrease of 5.137% in the scenario with a tap setting of 0.95.

Abstract

Smart Trash Can or smart trash can uses sensors and servo motor actuators. The sensor used is the ultrasonic sensor HC-SR04. Sensor 1 is used to detect the presence of people, sensor 2 is used to detect the height of the volume of the trash can, and the servo motor is used to open and close the trash automatically. This Smart Trash Can is equipped with a battery powered by solar cells. So that the trash cans that are inside and outside the room will still be able to communicate via IoT which in this study uses a complete device / laptop with the Telegram Messenger application as the monitoring system.

Abstract

The research aim to determine the effectiveness of the Digital Electronics Education and Design Suite Simulator to design a series of binary multipliers. This research methode begins by determining the problem boundary, where this binary number multiplier circuit is only able to perform 2 (two) bit binary multiplication operation. So the minimum value of the multiplication results is 0000 with a decimal value of 0 to 1111 with a decimal value of 15. The design is done by simplifying the problem by using the Boolean theorem. The results of this research is the construction of simulation circuit that can be used to perform multiplication operation 2 (two) binary numbers. Simplification of the circuit with the Boolean theorem method using Digital Electronics Education and Design Suite Simulator is able effectively design series of binary multipliers with an accuracy value of 100%.
