Iklim keselamatan merupakan persepsi pekerja tentang pentingnya perilaku aman saat bekerja berkaitan dengan kebijakan, keselamatan, prosedur, praktik, serta seluruh kepentingan dan prioritas keselamatan kerja. Iklim keselamatan yang buruk akan ditandai dengan peningkatan stress pekerja, komunikasi keselamatan yang buruk, dan kurangnya dukungan sehingga dapat menormalkan perilaku tidak aman, merusak kesadaran situasional, dan meningkatkan kemungkinan kecelakaan. Pengukuran iklim keselamatan dapat dijadikan perusahaan sebagai leading indicator untuk acuan dalam membuat/memperbaiki program keselamatan yang sudah ada. Penelitian ini bertujuan untuk menganalisis profil safety climate pada area support point di PT X Tahun 2025 berdasarkan dimensi komitmen manajemen, komunikasi keselamatan, aturan dan prosedur, lingkungan yang mendukung, akuntabilitas pribadi, dan pelatihan. Desain penelitian yang digunakan adalah cross sectional dengan metode pengumpulan data menggunakan kuesioner (data primer). Jumlah sampel yang dianalisis sebanyak 118 orang. Analisis data digunakan melalui analisis deskriptif dan inferensial (Uji Mann Whitney dan Kruskal Wallis). Hasil penelitian ini menunjukkan bahwa profil safety climate di area support point PT X tahun 2025 sudah baik, dengan rata – rata  nilai 5,18. Seluruh dimensi yang diukur mendapatkan rata – rata skor 4,98 – 5,31. Skor rata – rata safety climate pada kelompok usia, masa kerja, dan pendidikan menunjukkan adanya perbedaan signifikan pada dimensi komitmen manajemen, komunikasi keselamatan, dan pelatihan.

Safety climate is a worker's perception of the importance of safe behavior at work in relation towards policies, safety, procedures, practices, and overall safety interests and priorities. A poor safety climate will be characterized by increased worker stress, poor safety communication, and lack of support thus normalizing unsafe behavior, decreasing situational awareness, and increasing the likelihood of accidents. Safety climate measurements can be used by companies as a leading indicator in establishing / improving existing safety programs. This study aims to analyze the safety climate profile in the support point area at PT X in 2025 based on the dimensions of management commitment, safety communication, rules and procedures, supportive environment, personal accountability, and training. The research design used is cross sectional with data collection methods using questionnaires (primary data). The number of samples analyzed was 118 respondents. Data analysis was used through descriptive and inferential analysis (Mann Whitney and Kruskal Wallis Test). The results of this study indicate that the safety climate profile in the PT X support point area in 2025 is good, with an average score of 5.18. All dimensions measured get an average score of 4.98 - 5.31. The average safety climate score in the age, tenure, and education groups showed significant differences in the dimensions of management commitment, safety communication, and training.

Keluhan gangguan otot dan tulang rangka akibat kerja (GOTRAK) merupakan salah satu permasalahan kesehatan kerja yang umum dialami oleh operator alat berat di sektor konstruksi. Penelitian ini bertujuan untuk menganalisis hubungan antara faktor pekerjaan (jam kerja, shift kerja, masa kerja, beban kerja), faktor karakteristik individu (usia, waktu tidur, kebiasaan merokok, kebiasaan olahraga, konsumsi kafein, antropometri), dan faktor lingkungan kerja (getaran, pencahayaan, desain unit kabin) terhadap tingkat keluhan GOTRAK. Penelitian dilakukan secara kuantitatif dengan desain cross-sectional pada 100 operator alat berat di proyek konstruksi tambang di Sulawesi Tengah. Data dikumpulkan melalui kuesioner berbasis SNI 9011:2021 dan dianalisis menggunakan uji Chi-Square. Hasil menunjukkan bahwa 72% operator mengalami keluhan GOTRAK tingkat tinggi. Faktor yang memiliki hubungan signifikan antara lain jam kerja, beban kerja, usia, waktu tidur, kebiasaan olahraga, konsumsi kafein, antropometri, getaran, dan desain kabin unit. Penelitian ini merekomendasikan penguatan intervensi ergonomi dan pengelolaan kerja berbasis data antropometri guna menurunkan risiko GOTRAK pada operator alat berat.

Work-related musculoskeletal disorders (MSDs) are a common occupational health issue among heavy equipment operators in construction sectors. This study aimed to analyze the relationship between work factors (working hours, shifts, work tenure, workload), individual characteristics (age, sleep duration, smoking habits, physical activity, caffeine consumption, anthropometry), and environmental conditions (vibration, lighting, cabin design) with the severity of MSD complaints. A cross-sectional quantitative study was conducted involving 100 operators from mining-related construction projects in Central Sulawesi. Data were collected using a questionnaire based on the Indonesian national standard (SNI 9011:2021) and analyzed using Chi-Square. Results revealed that 72% of respondents experienced high levels of MSD complaints. Significant associated factors included long working hours, heavy workload, older age, insufficient sleep, low exercise frequency, caffeine intake, anthropometric mismatch, exposure to vibration, and cabin design inconsistencies. The findings suggest the need for ergonomic interventions and equipment design improvements based on anthropometric data to mitigate MSD risks among operators. Key words: MSD, heavy equipment, ergonomics, work factors, mining construction.

Kelelahan kerja (fatigue) merupakan kondisi yang dapat memengaruhi keselamatan dan kinerja operator alat berat di sektor pertambangan. Operator dump truck (DT) dan high dump truck (HD) bekerja dengan tuntutan fisik dan mental yang tinggi serta terpapar kondisi lingkungan kerja kabin. Penelitian ini bertujuan untuk menganalisis pengaruh faktor karakteristik individu dan lingkungan kerja kabin terhadap kejadian fatigue pada operator DT dan HD shift pagi di area tambang PT X, Kalimantan Utara. Penelitian ini menggunakan desain potong lintang (cross-sectional) dengan jumlah responden sebanyak 40 operator. Faktor karakteristik individu yang diteliti meliputi usia, masa kerja, durasi tidur, dan status hidrasi, sedangkan faktor lingkungan kerja kabin meliputi suhu, kelembapan, dan heat index. Tingkat kelelahan kerja diukur menggunakan kuesioner Subjective Self Rating Test (SSRT) dari Industrial Fatigue Research Committee (IFRC). Analisis data dilakukan secara univariat dan bivariat menggunakan uji Chi-Square, serta analisis Odds Ratio. Hasil penelitian menunjukkan bahwa tingkat kelelahan kerja berada pada kategori rendah hingga sedang dengan rata-rata skor 43,6. Tidak terdapat hubungan yang bermakna secara statistik antara faktor karakteristik individu maupun lingkungan kerja kabin dengan kelelahan kerja (p > 0,05). Namun, durasi tidur (OR = 4,200) dan status hidrasi (OR = 1,320) menunjukkan kecenderungan risiko kelelahan kerja. Oleh karena itu, diperlukan upaya pencegahan melalui pemeliharaan kebijakan fit to work dan penyediaan air minum di dalam kabin alat berat.

Work-related fatigue is a condition that can affect the safety and performance of heavy equipment operators in the mining sector. Dump truck (DT) and high dump truck (HD) operators perform tasks that require high physical and mental demands and are exposed to cabin working environment conditions. This study aimed to analyze the effect of individual characteristics and cabin working environment factors on fatigue among DT and HD operators during the morning shift at PT X mining area, North Kalimantan. This study employed a cross-sectional design involving 40 operators. Individual characteristics included age, length of employment, sleep duration, and hydration status, while cabin working environment factors consisted of temperature, humidity, and heat index. Fatigue level was measured using the Subjective Self Rating Test (SSRT) developed by the Industrial Fatigue Research Committee (IFRC). Data were analyzed using univariate and bivariate analyses with the Chi-Square test, supported by Odds Ratio analysis. The results showed that fatigue levels among operators were classified as low to moderate, with a mean fatigue score of 43.6. No statistically significant association was found between individual characteristics or cabin working environment factors and fatigue (p > 0.05). However, sleep duration (OR = 4.200) and hydration status (OR = 1.320) showed a tendency toward increased fatigue risk. Therefore, maintaining the fit-to-work policy related to sleep duration and providing drinking water inside the cabin are recommended as preventive measures.
