Abstract

Pesticide sprayer tools that are widely used by farmers are still using hands or fossil fuel machines, so they are still classified as traditional and ineffective methods. Some of the weaknesses of the traditional method include less practical, fossil fuels that will run out and the impact on the environment. Solar energy from the sun can be a solution to these problems. Solar panels are devices used to convert sunlight into electrical energy. In this study, a monocrystalline 30W solar panel was used as a tool used to capture sunlight. By utilizing solar power as an energy source sprayer and pump so that it can take advantage of the hand pressing the lever and refilling it manually. In addition, preferring solar power over fossil fuel engines can reduce the use of fossil fuels and further strengthen renewable energy that will not run out and is environmentally friendly. In this study, solar panels were installed above the head to maximize the capture of sunlight and also protect the head from the heat of the sun. The results showed that the battery energy required to spray the difference in battery percentage from 10 liters to 6 liters of liquid volume was 4% and from 6 liters to 2 liters of liquid volume was 6%.

Abstract

The use of smarthome technology to monitor and control homes is growing recently. The smarthome system requires the integration of several sensors to determine the conditions in the house. In a centralized smarthome system, all sensors are connected to a single node to perform data processing and communication which can result in system failure if this node is broken. In this study, we use a distributed model for the smarthome system. The designed system consists of three nodes, which are kitchen instrument, room instrument, and door instrument. These three instruments are equipped with RFID sensors, temperature sensors, gas sensors, and reed switch sensors to perform security features of the smarthome that can be accessed remotely via smartphones or computers. The results show that the system has been able to work well and can overcome the problem of failure on some instruments without causing the whole system to collapse. This smarthome system has an average delay of 2.21 seconds.

Abstract

Variable speed drives and the importance of controlling the speed of existing motors have attracted much attention with the advent of new electrical devices and magnetic materials. This paper is a comprehensive review of the application of VFD in energy saving electric motors. The aim is to identify energy saving opportunities and apply variable speed drives to existing electric motor applications. In this paper the authors hope to provide useful information for future variable speed drive applications such as fans, pumps, coolers, ventilators and as electric car propulsion. In this study, a series of frequency changes has been tested as an induction motor speed regulation (VFD), which in the results of this frequency change research can regulate the speed of the induction motor. In this study, the frequency change is still regulated analogously by changing the resistor size on the PWM signal generator IC for the MOSFET driver. For that the next research is expected to change the frequency can be done digitally

Abstract

Power flow analysis is used to determine the power flow parameters that are useful for planning the system to operate optimally as well as changes to existing systems, such as what happened at PT. Sele Raya Merangin Dua, which is currently making system changes in the form of additional loads. With the addition of this load, it is necessary to conduct a power flow analysis to determine the effect of increasing the load with the aim of knowing the system performance so that it can be in optimal condition. The research method used is qualitative-descriptive which is carried out in a simulation using ETAP 12.6 software where the results of the simulation will be tabulated and graphed. The results showed that the increase in load caused an increase in power generation and power distribution, especially on swing-buses to load-buses and branch buses. From the previous generation power of 1069.1 kVA increased to 1155.2 kVA but did not affect the performance of each power system equipment PT. SRMD and the electric power system are still in optimal condition.

Abstract

Information technology is an information service that is used as a form of interaction used by students during the COVID-19 pandemic. One of them as a medium of learning or communication. This study using quantitative methods that are analytical observational through the distribution of questionnaires through a google form. The distribution of the sample was 323 respondents with a research design in the form of a cross-sectional study approach. The results of data analysis based on univariate stated that 50.8% of respondents stated that learning dared to support learning activities but did not experience a significant increase, while bivariate analysis of information technology supported Unbari students' interactions with learning activities. during the covid 19 pandemic.

Abstract

One of the KRI fields is the Indonesian Football Robot Contest (KRSBI). In a match the robot does not know when the ball from the robot in one team is ready to be kicked into the opponent's goal. The kicking robot has an important role in creating goals against the opponent's goal. At the KRSBI solenoid kicker, Jambi University, using a booster converter zvz 390 to charge a capacitor bank which has a capacitance of 3900 F with a high voltage of 387 V, takes 6.34 seconds. However, 387 V is the maximum booster converter voltage. To minimize the occurrence of damage, a voltage of 310 V is set as the setpoint voltage for charging the capacitor bank with a charging time span of 4.3 seconds. Then the automatic control system for charging capacitor banks has a maximum error of 1.9%
