Abstract

In the electricity’s world, there are panels that are used to display electrical measurements or what is known as a Digital Panel Meter (DPM). This DPM measures physical quantities such as current, voltage, power, frequency and so on. In addition, this panel serves as a monitor for the quality of the electricity supply. In medium voltage systems, DPM is integrated with Automatic Meter Reading (AMR) which functions as a data collection tool for energy consumption of electricity consumers. So this DPM is a very important tool. Problems arise when connecting from one DPM to another, because this DPM usually uses RS-485 for its communication system. Such communication can only be carried out with equipment of the same standard. Therefore, it is proposed to design a Modbus RTU RS-485 converter to Modbus TCP/IP. This is done so that DPM communication can be directly connected to computers or to network devices such as routers, hubs and switches. Stages of research that begins with the analysis of problems and system requirements. Next do the design and realization. From the research conducted, the tool runs well. The test uses the modbus poll software as a comparison of the measurement results from the tool. The results show that the device data and those that appear on the modbus poll have high accuracy, for example, the device shows a voltage of 227.2 V; when using the software the result is 227.25 V

Abstract

The Covid-19 pandemic has started to subside. However, after the pandemic subsided the obesity rate in Indonesia continued to increase. The new habits formed after the pandemic are activities that can be done at home. This is an opportunity to be able to reduce obesity by doing physical activity at home. Physical activity undertaken specifically to lose weight. However, various problems arise when doing physical activity. Such as requiring expensive fees, monotony, and others. Mobile exergame is one solution to this problem. In previous research, exergames that use the brute force algorithm in determining physical activity take a long time. This problem will be solved using a greedy algorithm which also uses a maximum profit strategy. Descriptive statistics are used to compare the average time needed by the two algorithms to select the physical activity to be performed in an exergame. The results of this study indicate that in terms of time the greedy algorithm that uses the maximum profit strategy is proven to be faster than the brute force algorithm.

Abstract

In Indonesia, badminton was one of the most popular sport in various circles. Along with the times, robots can be designed as a device that can be used to play badminton. Robominton was badminton robot which is operated manually by human using a remote control or fully automatic. For a robot that controlled by manual-based, bluetooth or cable connection using joystick was used. This refers to the rules that have been set by DIKTI in “Robot Abu Indonesia (KRAI) 2015” Contest. As for the robot control system that we develop, are robotic system with manual control using android as a transmitter and bluetooth module HC-05 as a receiver. There is a robotic navigation control systems, transmission control systems shuttlecock, shuttlecock and servicing of control systems. ATmega 128 processor, four DC motors, with the EMS driver 30A H-Bridges was used as a hardware on shuttlecock transmission syste,. For shuttlecock services, self-designed pneumatic driver with solenoid valve was used. From the test results, the robot was able to navigate premises 11 formation movement, five pieces of shuttlecock transmission, and can serve up and down with a pneumatic
