Abstract

General Background: Project progress reporting is a critical component of construction management because project success is determined not only by completion time and final outcomes but also by continuous monitoring of work progress. Specific Background: PT. Albi Jaya Persada manages multiple construction projects, where project monitoring is constrained by distant project locations, delays in information delivery, difficulties in verifying field reports, and the accumulation of project documentation. Knowledge Gap: The existing monitoring process relied on manual reporting and communication methods that complicated verification, supervision, and decision-making activities. Aims: This study aimed to design and implement a web-based project progress monitoring system for PT. Albi Jaya Persada to support project supervision and reporting activities. Results: The developed system provides functionalities for project data management, sub-work monitoring, material tracking, progress documentation, complaint handling, and project supervision through dedicated interfaces for administrators, foremen, and directors. Black-box testing showed that all tested system functions operated according to the expected requirements and produced valid results. Novelty: The study introduces an integrated web-based monitoring platform that combines project progress reporting, material monitoring, documentation management, and communication of project constraints within a single system environment. Implications: The system supports directors in monitoring ongoing projects, reviewing project and material data, tracking work progress, and providing solutions to issues encountered during project execution.Highlights: Integrated platform supports project records, materials, documentation, and complaint management within one environment. Separate user interfaces were developed for administrators, foremen, and directors according to their responsibilities. Functional testing confirmed that all evaluated features operated as expected and produced valid outputs. Keywords: Web-Based Monitoring System; Project Progress Monitoring; Construction Project Management; Black Box Testing; Project Supervision

Abstract

General Background: Flood-prone areas require reliable early warning systems to support timely monitoring and response. Specific Background: Kedungbanteng Village, Sidoarjo Regency, experiences recurring flooding due to its lowland geographical conditions and proximity to major rivers. To address this issue, a flood warning system was developed using an ESP32-CAM microcontroller, an ultrasonic sensor, a camera module, fuzzy logic processing, indicator lights, an alarm, and Telegram-based notifications. Knowledge Gap: Previous flood detection approaches have faced challenges related to measurement accuracy and rapid information delivery, highlighting the need for a system capable of real-time monitoring and communication. Aims: This study aimed to develop and test Roy’s Flood Alarm Detector (RFAD) for real-time water level detection and remote flood monitoring. Results: The developed system measured water levels using an ultrasonic sensor, classified conditions into safe, alert, and emergency categories, activated visual and audio warnings at predefined thresholds, and transmitted notifications and images through Telegram. The ESP32-CAM successfully supported remote monitoring, while fuzzy logic was utilized to process water-level data. Novelty: The study integrates ESP32-CAM technology, ultrasonic sensing, fuzzy logic, camera-based visual verification, and Telegram communication within a single flood warning platform. Implications: The proposed system provides timely flood information that can support preventive actions and monitoring activities in flood-prone communities.Highlights: Real-time water-level monitoring was achieved through ultrasonic sensing and remote communication. Automatic alerts were generated using visual indicators, buzzer signals, and mobile notifications. Camera-based verification p Keywords: ESP32-CAM; Flood Warning System; Fuzzy Logic; Ultrasonic Sensor; Telegram Notification

Abstract

General Background: Compressed air systems require moisture control to maintain reliable operation and protect pneumatic equipment from damage caused by water vapor. Specific Background: Air dryer compressors equipped with evaporator systems are commonly used to reduce humidity in compressed air, while real-time monitoring is needed to observe operating conditions such as temperature, humidity, and pressure. Knowledge Gap: Conventional monitoring approaches often provide limited accessibility and do not integrate operational data into a cloud-based platform for continuous observation and data storage. Aims: This study aimed to design and develop an air dryer compressor with an evaporator system integrated with Google Sheet-based monitoring using Internet of Things technology. Results: The developed system employed DHT22 and pressure transmitter sensors connected to an ESP32 microcontroller to measure temperature, humidity, and air pressure, with data transmitted and displayed in Google Sheet in real time. Sensor testing showed close agreement with standard measuring instruments, while the monitoring platform continuously recorded operational parameters and generated organized data records. Novelty: The study presents the integration of an evaporator-based air dryer compressor with IoT-enabled monitoring and cloud-based data logging through Google Sheet within a single operational system. Implications: The proposed system provides accessible remote monitoring, structured data management, and continuous observation of compressor operating conditions, supporting reliable pneumatic system operation and maintenance activities.Highlights: Real-time data transmission enabled continuous observation of temperature, humidity, and air pressure parameters. DHT22 measurements showed close agreement with reference instrument readings during testing. Cloud-based records provided organized storage and remote access to operational information.

Abstract

General Background: Product quality control is a critical requirement in manufacturing industries to maintain production consistency, reduce defects, and support customer satisfaction. Specific Background: PT. XYZ, a wafer manufacturing company, experienced a packaging defect rate of 1.24% over a 12-month period, exceeding the company’s tolerance limit of 1%, with 7,962 defective packages recorded during production. Knowledge Gap: Previous studies have applied Six Sigma to packaging quality problems; however, limited studies have integrated Six Sigma (DMAIC), Root Cause Analysis (RCA), and a 5W+1H approach using a long-term observation period to identify the root causes of packaging defects in halal food products. Aims: This study aimed to identify the dominant packaging defect, determine its root causes, and formulate improvement recommendations to reduce defects within the company’s tolerance limits. Results: The findings revealed 12 types of packaging defects, with endseal corner tear defects representing the largest proportion at 44% of total defects. The average Defect Per Million Opportunities (DPMO) value was 1,131.46, and the average sigma level was 4.56. Root cause analysis identified five contributing factors: method, machine, man, environment, and material. Novelty: The study integrates Six Sigma DMAIC, RCA, fishbone analysis, and 5W+1H within a 12-month evaluation framework to provide a comprehensive diagnosis of packaging quality issues. Implications: The proposed corrective actions, including machine maintenance, standardized operating procedures, process monitoring, operator training, and material control, can serve as a reference for reducing packaging defects and improving production quality management in halal food manufacturing.Highlights: Endseal corner tear accounted for 44% of total packaging nonconformities. Average process performance reached 1,131.46 DPMO with a sigma level of 4.56. Five primary causal categories were identified: method, machine, man, environment, and material.
