Abstract

The sentiment is the action or point of view of a person based on experience. Evaluation for Offices is one way of getting emotions or feedbacks from clients. A person's response serves as an assessment of the quality of higher education standards. For the administrators to gather feedback from the clients/customers regarding their satisfaction or performance inside the offices or department premise, eSurMent was used as a gathering data tool. The study identifies the strengths and weaknesses of Educational Institution Services based on users' positive and negative responses. It provides a sentiment score from the qualitative data and a numerical response rating from the quantitative evaluation data, and a description of the evaluation results from users. Sentiment analysis is one way of surveys and polls to analyze the responses that researchers found to determine positive and negative reactions from students. Therefore, school administrators will be more aware of the shortcomings of users. Reports generated by the system can be used for self-improvement in the institution. In addition, the results of job evaluations can be used as the basis for opportunities, achievements, or marketing strategies.

Abstract

A control system in the form of an Automatic Transfer Switch (ATS) is needed when a blackout occurs from the PLN that will be transferred to the generator. The research problem was how to save costs for making ATS that can run efficiently. The purpose of this study was to find out how to save costs for making ATS that can run well and efficient. The method used was Research and Development. The Research and Development stages included: collecting data, designing, and testing. To save costs for making ATS, the researchers used the Timer Delay Relay (TDR), as using TDR reduces the cost of making tools because the component prices are relatively affordable. The way the ATS system works is when the PLN electricity is on, the battery will be charged by the battery charger, and when the PLN electricity goes out, the inverter will get a voltage supply from the battery, that was originally 12V will be changed to 220V. The TDR makes it easier to determine the appropriate time when the voltage is stable. Based on the experiment, the time when the voltage is stable is 6 seconds.

Abstract

Currently, air quality monitoring is only through satellites, so this monitor is only general; even though sometimes we need an air quality monitor to measure air quality in the room or gas emissions in motor vehicles and factories, this research uses an MQ135 sensor to measure CO2 gas emissions, a DHT11 sensor to measure humidity and a NodeMCU ESP8266 microcontroller as the central brain. The system is designed to provide accurate and efficient air quality monitoring through the Internet of Things (IoT). They are integrating Blynk as a mobile device monitoring application that offers easy access to real-time air quality data. The Blynk interface allows users to monitor air conditions easily, receive notifications, and access data history. Based on the experimental results and the accuracy of the integrated temperature measurement, the system provides a reliable solution for comprehensive air quality monitoring in various environments.

Abstract

One of the efforts to prevent fires is by providing occupational health and safety (K3) learning. In the learning process, the material is only in videos and power points about fire prevention and control. Conversely, students more easily understand contextualized material. One of them is an automatic fire extinguisher simulation. This simulation uses a fire sensor as its input, Arduino uno as its control, and a relay as an output from Arduino. This learning media was tested on 40 people with backgrounds as students and employees. Based on the results of this learning media trial, the average questionnaire assessment reached 87.6%, so this learning medium is effective as a learning medium for fire extinguisher simulation.

Abstract

Microcontroller technology is increasingly developing, so studying it requires a real device. The learning process for microcontroller practice at the Piksi Ganesha Indonesia Polytechnic Campus does not yet have sufficient tools, especially for Arduino Uno practice. The research aims to create a tool or trainer about Arduino Uno so that it can be used to support microcontroller learning in the Electronics Engineering Study Program. The research method uses Research & Development with stages including potential and problems, information gathering, product design, design validation, design improvement, product testing, and product revision. The research results are an Arduino Uno trainer with three inputs and three outputs. It is hoped that users can more easily understand the basics of microcontrollers with the media created.

Abstract

The initial phase of farmers cannot quickly regulate the selection of the quality of produced chili peppers due to limitations in manpower and time. This can lead to inaccuracies in chili selection, resulting in not all marketed chilies being in good condition. The color quality of chili peppers is one of the characteristics that can be observed. Some important factors that also concern chili farmers include the level of chili ripeness, adverse effects on consumers, and a decrease in farmers' or traders' turnover. Based on these problems, researchers developed a design for a chili ripeness sorting tool with a color sensor to sort chili color quality. This research model utilizes Research & Development, with the following stages: potential and problems, information collection, product design planning, product development, product testing, and product revision. The chili ripeness sorting tool based on Arduino Uno utilizes the TCS 3200 color sensor as a device to capture chili color data and a servo motor as an actuator. Based on product testing, the success rate of color readings is 93.33%. This product is expected to assist chili farmers in sorting and determining the quality of chilies to be sold to consumers.
