Abstract

This study focuses on enhancing the selection process for software developers by integrating the Fuzzy Analytic Hierarchy Process (F-AHP) and the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (F-TOPSIS). The primary objective is to address the uncertainties and ambiguities in determining evaluation criteria and weights, thereby facilitating accurate decision-making when faced with multiple criteria and alternatives. Conducted within a software development company in Bandung, Indonesia, the study involved evaluating ten potential candidates for the software developer position. The methodology employed F-AHP to assess the importance of each criterion through pairwise comparisons, and F-TOPSIS to rank the candidates based on these criteria weights. The results revealed that Candidate CK-7 exhibited the highest closeness coefficient (CCi), making them the top candidate, while CK-4 ranked the lowest. This integrated approach provided a systematic and transparent framework for decision-making, demonstrating its effectiveness in optimizing recruitment processes. The study contributes to the field by offering a robust decision-making tool that can be adapted to various industries, ensuring the selection of high-quality employees who meet necessary competencies, thereby improving overall productivity and performance.

Abstract

Oyster mushroom (Pleurotus ostreatus) has great potential in agricultural development with increasing global market demand. This research develops an intelligent cultivation system based on Mamdani fuzzy and IoT to control air temperature, air humidity, and soil moisture automatically and in real-time, using DHT22 sensor, resistive soil moisture sensor, and ESP32 as microcontroller. The test results show a high level of accuracy, with an average sensor error of 1% for air temperature, 3.8% for air humidity, and 9.3% for soil moisture. The validation of watering, humidification, and fan prediction times compared to MATLAB calculations is excellent, with MAPE values of 1.52%, 1.43%, and 1.43%, respectively. This system offers a more accurate and responsive automated solution compared to conventional cultivation management. Further testing on actual oyster mushroom farms is required to determine whether the system can adapt to varying environmental conditions. The system relies heavily on a stable internet connection to optimally perform the real-time Mamdani fuzzy calculation function.

Abstract

Road damage in Lampung Province poses a serious threat to public safety and transportation, necessitating immediate government assistance. Despite the necessity for fast repair, there has been a lack of an appropriate platform for public reporting, making road inspections inefficient and error prone. This study makes two significant contributions: (1) the creation of a comprehensive dataset documenting road damage in Lampung, using samples collected in Pesawaran Regency, and (2) the development of an automated road damage identification and reporting system based on the YOLOv7 object detection model. The technology detects damage types such as alligator cracking, corrugation, depression, and potholes and provides real-time geolocation to improve reporting accuracy. Furthermore, it allows the public to report road damage. The model was trained on 1,200 pictures over 100 epochs, yielding a mean average precision (mAP) of 0.6. System performance was evaluated using precision and recall metrics, and compatibility testing confirmed that the system works reliably across various devices and browsers. This research enhances road maintenance by making inspections faster and more precise, while also promoting greater public involvement. Future work could integrate additional data sources, such as satellite imagery or IoT technology. to further increase the system’s scalability and accuracy.

Abstract

Government policies that carry out large-scale social restrictions during the Covid-19 period have had an impact on reducing air traffic both for landings and takeoffs, which will have an impact on the life of runway services. Service life is the strength of road pavement in standing the repetition of permit loads before experiencing failure, by knowing that the service life can be directly used to determine the right time for runway maintenance. The purpose of this research is to determine the impact of the Covid-19 pandemic on the life of runway services. The method used in this research is the FAA method with the help of FAARFIELD software, this software calculates the service life based on the CDF value of each aircraft. The data used is secondary data in the form of aircraft type data, CBR ground, and existing pavement data. From the results of the research, it is known that the COVID-19 pandemic has a positive impact on the life of runway service by increasing the life of runway service by 4 years, where in the condition of covid-19 conditions it has a CDF value of 0.20 with a service life of 19 years and in normal conditions the CDF value is 0.22 with a service life of 15 years. The results of this research contribute to decision-making in carrying out maintenance and repairs on the runway of Soekarno Hatta International Airport so that the runway can operate sustainably in accordance with performance requirements throughout the life of the plan, to maintain flight safety and comfort.

Abstract

Ensuring handrails structural integrity and safety in industrial hopper systems is crucial for worker protection and operational efficiency. This study investigates handrail systems design, stress analysis, and safety factors using Finite Element Analysis (FEA) via SolidWorks. Observations of existing systems revealed deficiencies such as improper welding techniques and unstable mounting, which were addressed through an improved modular handrail design that incorporated standardized dimensions, full-welded joints, and clamped baseplates. The methodology included a comprehensive simulation of the static loads, stress distributions, and deformation patterns validated through physical load testing. Results demonstrated significant improvements, with a reduction in the maximum stress by 25% and deformation by 40%, yielding a safety factor of 1.85. The findings confirm compliance with the industrial safety standards and highlight the robustness of the proposed design. This research contributes to advancing workplace safety through a replicable framework that combines simulation and empirical validation, offering broader applicability to safety-critical industrial components.

Abstract

White canes are an ideal choice for blind person to do independent mobility because of its relatively cheap price. However, whitecane has the disadvantage of only being able to identify objects in front of it when they have been touched and cannot provide a choice of direction. This study developed a prototype whitecane with a feature that can provide a choice of direction based on the results of identifying the distance of the object to its user. This prototype was designed and implemented using two ultrasonic sensors installed on the stick as a replacement for the spatial sensing system. Both distance data from the sensors are processed in the Arduino Nano microcontroller to carry out the Fuzzy process stages. Fuzzy input process, rule-based Fuzzy inference, and Defuzzification for decision output. The results of the decision are translated into voice information to the user. Experiments with three scenarios showed that the utilization of the system with constant contact O&M technique showed a success rate of 100% while the other two techniques were only 33.3%. So the constant contact O&M technique can support effective mobility for the use of assistive aids and can be developed into a new technique.
