Abstract

A good work environment is a key factor in fostering a positive work culture in the construction industry. According to a study conducted by the Ministry of Public Works and Public Housing (PUPR), approximately 45% of construction workers feel that an uncomfortable work environment contributes to their low productivity (PUPR, 2022). Unsafe work environments, such as lack of protection from extreme weather and inadequate health facilities, can lead to stress and dissatisfaction among workers. For example, a building construction project in Jakarta carried out by PT XYZ experienced delays because workers lacked adequate access to rest areas and proper sanitation. This demonstrates that investing in good facilities can improve worker comfort and productivity. Training and skills development also play a crucial role in fostering a work culture. Data from the National Professional Certification Agency (BNSP) shows that only 30% of construction workers receive adequate training in their field (BNSP, 2023). Lack of training can lead to workers feeling insecure in carrying out their tasks, which in turn can reduce productivity. For example, a building renovation project in Surabaya experienced numerous technical errors due to workers lacking sufficient skills in using heavy equipment. Therefore, construction companies need to invest in ongoing training programs to improve workers' skills and knowledge.

Abstract

Abstract A sluice gate is a supporting structure in a dam, reservoir, river, gutter or ditch which functions to regulate the control of water discharge in each flow. With good and controlled irrigation, irrigation systems and waterways from upstream to downstream can be controlled, so that the need for water in agriculture, fisheries, plantations, and industry can be met and relied on properly. The sluice gate functions to control water so that it can prevent flood water in a fast and high flow. The flowing water will lead to the river to the ocean. Therefore the author will design a prototype of an Internet of Things (IoT) based automatic sluice monitoring system. this system requires interrelated components, namely NodeMcu as the control center of the system as well as a wifi module and the relay module as an electrical switch to turn on or off and use the blynk application.

Abstract

Product packaging quality plays a crucial role in maintaining product safety, reducing rework, and sustaining company competitiveness. This study aims to reduce defects in 25 kg wheat flour packaging at PT. XYZ by identifying dominant defect types and analyzing their root causes. A Soft Systems Methodology (SSM) approach—an interpretive, systems-based framework used to analyze complex, unstructured problem situations—was applied to structure the problem, develop conceptual models, and propose improvements. Based on production data, 653 packaging defects were recorded. The dominant defects were packaging leakage at the seams (51.60%) and damage during loading (36.29%), representing 87.89% of total defects. Root cause analysis using Pareto and fishbone diagrams identified human factors, improper methods, and material quality as the primary contributors. Improvement proposals include selecting higher-quality thread, optimizing operator working schedules, providing ergonomic support tools, establishing loading limits, and strengthening SOP implementation. The implementation of these improvements is expected to reduce rework levels, improve productivity, and enhance packaging reliability.

Abstract

Vehicle interior cleanliness affects travel comfort, particularly when a car is used by families or multiple passengers. This study developed and tested an ergonomic car trash-bin prototype using Design Thinking and Quality Function Deployment through the House of Quality (HoQ). The study used archived product-development evidence, including aggregate questionnaire charts, an empathy map, existing-product observations, brainstorming records, HoQ, hand sketches, fabrication videos, static-fit photographs, and prototype-testing documentation. Because respondent-level questionnaire data were not retained, the analysis was descriptive and did not use inferential statistics. Three user needs were prioritised: easy reach, no interference with passenger movement, and prevention of waste scattering. The documented initial under-seat concept measured 440 x 450 x 200 mm and did not fit the selected vehicle space. After cardboard trials at the highest and lowest seat positions, the revised under-seat design measured 280 x 250 x 100 mm and achieved documented static fit. An initial door-trim trial was blocked by the cavity geometry; a custom door-pocket configuration of 160 x 65 x 130 mm was subsequently documented in static placement. The 2 mm black-acrylic prototype was assessed only for basic fit and intended use. The findings support vehicle-specific product development and identify the need for dynamic driving, usability, and cost-validation tests. For automotive-accessory designers and small manufacturers, this record offers a practical, replicable reference for translating cabin-cleanliness complaints into a vehicle-specific prototype before committing to tooling and mass production.
