Abstract

A waiter is a team member in a restaurant or store responsible for welcoming new arrivals or seeing off departing customers, particularly at the main entrance of the establishment. Currently, the process of welcoming customers relies entirely on human workers, which consumes both time and effort. Therefore, an automated welcoming system is needed to enhance efficiency in terms of time and energy. In this study, the research and development method is employed. The automated welcoming system is built on Arduino technology, involving the use of PIR sensors, Arduino Uno R3, DFPlayer, and a Speaker. During the testing of this product, PIR sensors are utilized as human motion detectors. Arduino Uno R3 functions as the brain of the system, receiving data from the PIR sensors. When the first PIR sensor detects motion, Arduino Uno R3 activates the DFPlayer to play sound through the Speaker. If the second PIR sensor detects motion, the first PIR sensor is turned off for 3 seconds. This product has the capability to detect motion up to a maximum distance of 3 meters.

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.

Abstract

One of the repair works on the Power Train Havy Dum Truck (HD 787-5) unit is general overhaul work, which includes replacing components or overhauling the final drive assembly unit. The solution to the uninstallation and installation work is to replace the final drive. The disassembly and assembly work process has a level of difficulty, so technicians need precision and accuracy in assembling the drive shaft on the final drive so that the time for this work process requires a long lead time. components) and has potential K3 hazards for technicians (manpower). The difficulty of inserting the drive shaft into the differential gear and rotating the ring gear in the final drive is a problem due to the long processing time. The innovation carried out is how to position the drift shaft parallel to the position of the differential gear, thus requiring a special tool to leverage and at the same time to rotate the drive shaft so that it can change the position of the position, with this leverage and position change effort it can speed up the removal and installation process and working time technicians are more effective and efficient in terms of labor costs on general overhaul work.

Abstract

There are a small number of villages across Indonesia that have access to telecommunications. Operators find it less profitable to build conventional telecommunications infrastructure in rural areas. 4G networks need to be developed in various ways, but the development has not yet achieved the quality of service that people need. This article evaluates the performance of developing an OpenBTS4G Network using 5GS with the Universal Software Radio Peripheral (USRP) B210 device to make the network an economical communication solution for villagers. The system can be mobilized and set up whenever the cellular infrastructure is reactivated. After our configuration, the 4G network was detected on several cellular phones, but the transmitted network only covers 5m area, because the power used has not been able to cover a wider area. The development of this network is a solution in building a Network so that it will help people who live in blankspot areas. This research also aims to show that the Universal Software Radio Peripheral (USRP) B210 can be used to provide and 4G Network.
