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

This research aims to implement a QR Payment system as an effort to increase attractiveness and encourage greater community participation in waste management at KSM BIMA, facilitating transactions, particularly the exchange of customer points for goods. The analytical method employed in this research is Design Thinking. The results demonstrate the successful implementation of the QR Payment system in the Android application of KSM BIMA waste bank. The prototype creation involved three stages: the first stage for developing an Android application prototype for customers and administrators, the second stage for QR Payment system development and creating Android applications for partners, and the final stage for adding several program features to the QR Payment system, setting an age limit for point redemption and generating reports for each application. Testing using the Black Box Testing method indicates that the implemented system functions effectively.

Abstract

Rainfall is water that falls to the ground surface over a certain period and is measured in millimeters (mm). Rainfall is essential for the life of living things. Forecasting plays a significant role in decision-making in modern times, with two main methods: causal models and time series. Time series models have five types of data patterns: random, constant, seasonal, cyclical, and trend. For rainfall forecasting, the Double Exponential Smoothing and Triple Exponential Smoothing methods are used for trend pattern data. This research compares the two approaches based on error values using average rainfall data in Bojonegoro. The results show that Double Exponential Smoothing has a Mean Absolute Percentage Error (MAPE) of 0.6996%, while Triple Exponential Smoothing has a MAPE of 119.1497%. So, Double Exponential Smoothing is more accurate.

Abstract

This study evaluates the application of Multi Attribute Utility Theory (MAUT)-based decision support systems in the recruitment process of financial managers in technology companies "TechInnovate". This study aims to identify the extent to which the use of MAUT can increase objectivity and effectiveness in candidate selection. The quantitative method was used by collecting data from 50 candidates who volunteered for this position. The assessment criteria that have been determined include Education and Qualifications, Work Experience, Analytical and Financial Skills, Communication Skills, Leadership and Team Management, Ethics and Integrity, Technology Capabilities, Adaptability and Innovation, Decision Making Ability. Data is collected through scores assigned to each criterion for each candidate, which are then aggregated taking into account the relative weights of each criterion. Statistical analysis is applied to evaluate the distribution of scores and the effectiveness of the system in selecting the most suitable candidates. Results from this study show that the application of MAUT is significant in improving objectivity in recruitment decision making, with high scores strongly correlated with expected job performance in in-depth interviews and follow-up evaluations. This study proves that integrating a systematic approach in recruitment not only strengthens the selection process but also promotes data-driven and objective decisions. The implications of this research are relevant for companies operating in dynamic and technology-centric environments, suggesting the integration of MAUT-based decision support systems as an effective strategy in the recruitment process.

Abstract

BUMDESMA as a village-owned business entity needs a website for a wider information dissemination process. Not only as a means of sharing information quickly, accurately and easily, websites are also used to maintain the credibility and existence of a company in developing its business. BUMDESMA Kompak Sejahtera Lkd is one of the BUMDESMA that does not yet have a website for disseminating information or means for conducting business transactions. So far, information dissemination has only been limited to distributing printed brochures offline. To increase the dissemination of information on the existence and existence of BUMDESMA Kompak Sejahtera Lkd, in this research a BUMDESMA website was designed using the prototype method. To get an effective and efficient website design, the Laravel framework was chosen as the solution. After designing the BUMDESMA website, it is hoped that information about BUMDESMA Kompak Sejahtera Lkd will become wider so that it can help increase business activities at BUMDESMA.

Abstract

The research aims to determine the effect of different spark plug variations on fuel consumption. The method used is a descriptive method. The tools and materials used are: copper spark plugs, platinum spark plugs, iridium spark plugs, 5 liter measuring cup, and pertalite. Fuel consumption analysis compared copper, platinum and iridium spark plugs with rpm 700, 1000, 1500, and 2000. Test results: 1) Fuel consumption for copper spark plugs with rpm 700, 1000, 1500, and 2000, namely 40ml, 10ml, 15ml and 10ml. 2) Fuel consumption for platinum spark plugs with rpm 700, 1000, 1500 and 2000, namely 20ml, 5ml, 25ml and 20ml. 3) Fuel consumption for iridium spark plugs with rpm 700, 1000, 1500 and 2000 is 50ml, 10ml, 10ml and 10ml. So platinum spark plugs are more fuel efficient than copper and iridium spark plugs.

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.

Abstract

Three-dimensional (3D) scanning technology is pivotal in manufacturing, product design, and architecture, enabling precise digital reconstructions of real-world objects. However, existing 3D scanners are often costly and complex, hindering accessibility. To address this, our study presents a cost-effective 3D scanning system using Arduino technology. Utilizing an Arduino Nano, GP2Y0A21YK0F IR Sensor, stepper motors, motor drivers, and an SD card module, our system offers a simple solution for scanning small objects and creating 3D models. The scanner measures object distance, rotates a work table, and captures scan data, processed with MeshLab software. Successful scanning demonstrates affordability and automation. Future work will focus on optimizing accuracy and scanning speed.
