Abstract

Introduction: The manufacturing industry transforms various materials, substances, or components into new products using mechanical, physical, or chemical forces. Safety climate refers to the perception of workers of prioritizing safety over organizational goals in the workplace. PT A, B, and C are manufacturing companies located in the Jababeka area. This study aims to identify the main factors that influence the perception of workers of safety climate in PT A, B, and C. Methods: A quantitative study with a cross-sectional design was conducted in August 2021 to analyze the safety climate of three companies. This study focused on various factors, such as leadership, risk management, implementation of occupational health and safety management system (OHSMS), regulation, management commitment, worker engagement, and worker competence. The sample size consisted of 330 workers selected from the three companies using the Lemeshow formula from a total of 1500 workers using the cluster sampling technique with the analysis of variance (ANOVA) test. Results: The results showed that risk management had the lowest score among the safety climate sub-variable for the three companies. Conclusion: The ANOVA test revealed a significant relationship among the safety climate variables. Furthermore, it is necessary to prioritize management in terms of policy and administration by involving all departments.

Abstract

Penelitian ini mengkaji penerapan metode SNI 9011:2021 untuk analisa ergonomi pada operator alat berat di proyek konstruksi. Operator alat berat sering mengalami keluhan GOTRAK akibat postur kerja yang tidak ergonomis, khususnya di area leher dan punggung bawah. Studi ini dilakukan dengan metode studi kasus pada operator tiga jenis operator alat berat, yaitu excavator, crawler crane, dan dump truck. Data dikumpulkan melalui kuesioner dan daftar periksa ergonomi berdasarkan pedoman SNI 9011:2021. Hasil studi menunjukkan bahwa beberapa operator telah mengalami GOTRAK yang disebabkan oleh postur kerja yang tidak ergonomis. Keluhan terbanyak ditemukan pada leher, punggung bawah, dan tangan. Rekomendasi yang diberikan mencakup intervensi ergonomi seperti perbaikan desain kursi yang dapat diatur ketinggian, sudut kemiringan, serta penambahan suspensi atau jenis busa pada kursi untuk mengurangi getaran. Penerapan rekomendasi ini diharapkan dapat mengurangi risiko gangguan kesehatan, meningkatkan keselamatan serta produktivitas di lingkungan kerja konstruksi.

Abstract

Kelelahan merupakan salah satu faktor penyebab kecelakaan transportasi, ditandai dengan menurunnya kinerja fisik dan mental yang mengakibatkan kurangnya kewaspadaan karena rasa kantuk. Penelitian ini bertujuan untuk mengetahui faktor risiko dan faktor pendukung kelelahan pada operator alat berat. Penelitian dilakukan pada operator alat berat di 3 tambang batubara di Kalimantan (2 area di Kalimantan Timur dan 1 area di Kalimantan Selatan), melibatkan 353 operator alat berat yang bekerja dengan 3 sif. Hasilnya menunjukkan bahwa keluhan kelelahan semakin tinggi dengan meningkatnya usia, lama kerja, dan kerja pada sif 3 (malam hari). Kelelahan paling banyak dirasakan oleh operator dump truck (bagian hauling) yang dipengaruhi oleh faktor-faktor pekerjaan (postur saat bekerja, faktor variasi pekerjaan, beban kerja dan vigilance) dan faktor-faktor bukan pekerjaan (kondisi medan atau area tambang yang berisiko, penerangan yang kurang pada malam hari, dan rute yang selalu berubah). Faktor lainnya berkaitan dengan masalah sosial-psikologis, baik yang berhubungan dengan pekerjaan maupun lingkungan kerja, seperti waktu istirahat, standar gaji yang belum memadai, pengaturan jadwal cuti yang sering tidak jelas, dan masalah karier. Disimpulkan, secara umum kelelahan meningkat dengan bertambahnya usia dan lama kerja, dengan kelelahan yang lebih besar pada pekerja sif 3. Umumnya, penurunan waktu reaksi pekerja sif malam lebih besar daripada waktu reaksi pekerja sif siang. Fatigue is one of the causes of transportation accidents, characterized by reduced physical and mental performance resulting in reduced alertness due to drowsiness. The present study was to determine the risk factors and contributing factors of fatigue suffered by heavy equipment operators. The study was conducted at three coal mining sites in Kalimantan (2 areas in East Kalimantan and 1 area in South Kalimantan) involving 353 heavy equipment operators who work in shifts. It was found that fatigue complaint is higher by older age, longer work, and work at shift 3 (night time). The fatigue is mostly complained by dump truck (hauling part) operators which was influenced by work-related factors (work posture, job variety, workload, vigilance) and non-work related factors (terrain or mine risk area, lack of lighting at night, and route track which is always changed). Another factors related with socio-psychological factors, either related with job or working environment, such as adequacy of rest time, remuneration system, leave system, and insecure career. It is concluded that in general the fatigues were increased as the worker ages were older and longer duration of work, with higher fatigues were suffered at shift 3. Generally, reduced reaction time among shift 3 workers is higher than that those of daytime shift.

Abstract

Background: Not all of awkward postures that exist in the industry should be eliminated. Due to the fact, awkward posture can not be separated from daily work activities. Any movement that makes the body angle away from the normal position, can be said to be an awkward posture. Misconceptions related to the concept of awkward posture are followed by the fact that the assessment’s concepts of the observation method that are often used to assess awkward postures (REBA, RULA, and OWAS) is not accordance with the theory it should be. That condition can reduce the effectiveness of controlling musculoskeletal system disorders. To overcome this, it is necessary to review the literature that explains what variables can affect the severity of awkward postures. Method: This study uses a narrative literature review method with the aim is for describing the relationship between duration, frequency, and angle inclination of posture with the severity of awkward postures. Results: 15 literatures were obtained from the online databases of Science Direct, ProQuest, and Google Scholar, with details of 9 literatures using the semi-experimental method, 5 literatures using the cross sectional method, and 1 literature using the systematic literature study method. Conclusion: Based on results of the literature, there are some evidences that proof the linear relationship between the duration, frequency, and angle inclination of postures with the severity of awkward postures.

Abstract

There were 508 cases of Transjakarta Bus accidents in 2021. Investigation results by the National Transportation Safety Committee (KNKT) revealed that one of the causes was driver fatigue. This study aims to describe fatigue complaints and analyze fatigue-related risk factors in Drivers of Transjakarta BRT (Bus Rapid Transit) and Non-BRT in 2022. This research is a quantitative study with an analytical descriptive research design. The research sample was 124 Drivers of Transjakarta BRT and Non-BRT. The independent variables in this study are work-related risk factors (Work Duration, Shift Work, Rest Time, Commuting Time, and Workload). The covariates in this study were worker-related risk factors (Age, Gender, BMI, Caffeine Consumption, Hypertension, Diabetes, and Sleep Quantity). This cross-sectional study used the Swedish Occupational Fatigue Index (SOFI) questionnaire to measure fatigue and the NASA-TLX questionnaire to measure workload. The data analysis is bivariate with the Chi-square test and multivariate with logistic regression. The study result showed that 48.4% (60) drivers experienced fatigue, and 55.6% (64) drivers did not experience fatigue. BMI, age, and sleep quantity have a significant relationship with fatigue. The most dominant work-related factor that affects fatigue is workload, although no significant relationship was found.

Abstract

This study aims to understand supervisors' perceptions of the effectiveness of Geotab as a control measure for mitigating the risk of collisions involving light vehicles. Conducted in Division X of PT. X, a mining industry, from February to June 2023, this descriptive, semi-qualitative study collected data through control effectiveness questionnaires, interviews, and document review. The variables studied include the relevance, coverage, reliability, reactivity, resource competence, and supervision system of Geotab. Questionnaire results showed supervisor perception scores of 3.09 for relevance (appropriate), 3.10 for coverage (appropriate), 3.06 for reliability (appropriate), 2.99 for reactivity (appropriate), 2.93 for resource competence, and 2.95 for the supervision system (appropriate). Interview results highlighted keywords such as "already appropriate" for relevance, "light vehicle operation scenario" for coverage, "operates well" and "system errors" for reliability, "unable to provide immediate alerts" for reactivity, and “sufficient understanding” for resource competence, while supervision revealed a top-down evaluation approach. A review of Planned Job Observation (PJO) documents in June 2023 confirmed that all light vehicles observed in 33 PJOs were equipped with Geotab. In conclusion, relevance, coverage, resource competence, and supervision system variables were deemed appropriate, while reliability and reactivity were moderately appropriate. Keywords: control effectiveness, geotab, supervisor's perception.
