Abstract

PT. Perkebunan XIII Kebun Tabara mempunyai permasalahan yang dihadapi yaitu kenyamanan dan keselamatan pekerja. Diharapkan dari penelitian ini dapat membantu perusahaan menyelesaikan permasalahan kesehatan, kenyamanan dan keselamatan pekerja dan meningkatkan kesejahteraan pekerja. Penelitian ini melakukan analisis postur kerja terhadap pekerja pemanenan kelapa sawit dengan menggunakan SNI 9011;2021 untuk mengidentifikasi postur kerja dan risiko pekerja serta akibat dari postur kerja untuk mengetahui skor postur kerja serta usulan perbaikan. Berdasarkan data Survei gotrak yang diambil dari empat pekerjaan yaitu penurunan tandan buah segar dari pohon, pengangkutan tandan buah segar, pengutipan berondolan, memindahkan tandan buah segar, pekerja mengalami keluhan rata-rata pada leher, pinggul, lengan, dan betis yang mendapat skor 3 berdasarkan tingkat keparahan dan tingkat frekuensi keluhan pekerja. Berdasarkan hasil penelitian diketahui empat pekerjaan mempunyai durasi siklus dan aktivitas yang berbeda tiap pekerjaannya yang membuat potensi yang sakit yang dialami pekerja berbeda-beda tiap pekerjaan Hasil yang didapatkan dari pengukuran adalah terdapat 4 postur yang menjadi penyebab terjadinya keluhan yaitu leher memuntir, tangan tidak ditopang, beban berat, dan pengangkatan beban secara manual, untuk itu diperlukan mitigasi risiko K3 pada pekerja. Berdasarkan Survei ERF diketahui dari 4 pekerjaan yang dilakukan pekerja pekerjaan dengan potensi bahaya ergonomi adalah pengangkutan TBS, Hasil dari analisis potensi bahaya pada penurunan TBS didapatkan nilai risiko berbahaya, pada pengutipan berondolan didapatkan nilai risiko berbahaya, dan pada perpindahan TBS ke TPH didapatkan nilai risiko berbahaya. Selanjutnya dilakukan usulan perbaikan dengan pengedalian risiko yang dapat diterapkan untuk mengurangi potensi terjadinya bahaya berupa alat tracktor scissor lift. Alat ini berfungsi untuk memindahkan proses pengangkutan TBS yang sebelumnya diangkat ke truck menjadi ke tacktor. Dengan adanya tracktor ini pekerja tidak perlu mengangkut TBS langsung ke dalam truck dikarenakan scissor lift dari dump tractor ini dapat mengangkat dump ini lebih tinggi dari tinggi dump truck, hal ini dapat dilakukan dengan cara posisi truck dibuat lebih rendah dari posisi tracktor dengan memanfaatkan tinggi tanah pada TPH setempat, TBS dapat diangkut langsung ke dalam truck menggunakan tracktor scissor lift dan mengurangi postur yang tidak normal dan mencegah forceful extertions.

Abstract

Sedentary office work increases musculoskeletal risk, underscoring the need for non-intrusive, real-time posture monitoring. This study presents a computer vision approach that classifies ergonomic versus non-ergonomic sitting postures using upper body key points extracted by MoveNet thunder. Images from 30 participants were captured from frontal and side views, and labeled according to SNI 9011:2021 criteria. Seventeen key points were detected, with head-to-hip landmarks retained, then normalized and centered. Three classifiers—adaptive boosting (AdaBoost), extreme gradient boosting (XGBoost), and a multi-layer perceptron (MLP)—were trained and evaluated with 10-fold stratified cross-validation. XGBoost achieved the best performance, with accuracy 93.0%±1.9%, precision 94.6%, recall 91.4%, F1-score 92.9%, and area under the receiver operating characteristic curve (ROC-AUC) 0.974±0.010, outperforming MLP and AdaBoost. The method supports privacy-preserving, on-device inference and is suitable for integration into smart office systems to reduce exposure to high-risk postures. Limitations include controlled capture conditions and an upper body focus; future work will expand posture taxonomy and real-world deployment.

Abstract

The use of smartphones for gaming among university students is increasing and often carried out for long durations with poor ergonomic posture. This condition has the potential to cause musculoskeletal disorders, one of which is Text Neck Syndrome (TNS), characterized by neck pain and disability due to excessive forward head flexion. This study aimed to analyze the risk of TNS among Industrial Engineering students at Mulawarman University who play smartphone games and to identify the relationship between screen time and playing posture with the level of neck disability. This research employed a quantitative design with a descriptive analytic approach. The study population consisted of 265 active students from the 2020–2024 cohorts. The sample was determined using purposive sampling, and 50 respondents who met the inclusion criteria were selected. Data were collected using the Neck Disability Index (NDI). Data analysis was performed descriptively and with the Spearman Rank test to examine the relationship between screen time, playing posture, and NDI scores. The results showed that most respondents experienced mild disability (34%), followed by moderate disability (26%), no disability (18%), severe disability (12%), and very severe disability (10%). Respondents with >5 hours of screen time per day had a higher proportion of moderate to severe disability. Moreover, students who played in a cross-legged sitting posture were more likely to experience moderate to very severe disability (63%) compared to those who played while sitting on a chair (44%). In conclusion, university students who play smartphone games are at risk of developing TNS with varying levels of disability, particularly those with longer screen time and cross-legged posture.

Abstract

Along with the growth of the palm-oil industry in Indonesia, work-related musculoskeletal disorders (WMSD) experienced by palm-oil harvesting workers also increased. This paper aims to evaluate ergonomic risk factors among harvesting palm workers in East Kalimantan and to propose suggestions to mitigate the risks. A total sample of 70 workers from 3 plantations in Muara Wahau, Babulu, and Muara Badak was observed in 2023. Gotrak survey and ergonomic risk factor (ERF) questionnaire of SNI 9011:2021 were utilized for determining the WMSD and identifying the ergonomics risk, respectively. The result showed that 91% of workers experienced pain after work, and 72% frequently experienced physical fatigue. The Gotrak survey on cutting and carrying bunches activity revealed high exposure risk for the neck (97%), followed by the shoulder (77%) and knee (55%). Meanwhile, during the activity of loading bunches onto the truck, high exposure risk occurs in the shoulders (73%), elbows (53%), and knees (53%). The result of the Kruskal-Wallis statistical test indicates that there is a difference in Gotrak levels among the three locations. The Gotrak level in Muara Wahau is the highest, followed by Babulu and Muara Badak. The results of the ERF questionnaire showed that loading to truck, followed by carrying FFB to the fruit collection point, were the two activities with high ERF scores, i.e., 39 and 34, respectively. Finally, improvements such as stretching exercises before and during work, as well as redesigning ergonomic T-hook and egrek, will mitigate the risk.

Abstract

Musculoskeletal disorders (MSDs) remain one of the leading occupational health problems in manual material handling activities, adversely affecting workers' well-being, operational efficiency, and long-term organizational sustainability. This study aimed to comprehensively assess ergonomic risks in the Logistics Department of PT Surya Hutani Jaya, an industrial plantation forestry company in Indonesia, by integrating workers' subjective complaints with objective ergonomic and biomechanical assessments. A descriptive quantitative case study was conducted using a total sampling approach involving five logistics workers performing three critical activities: incoming goods handling, chemical mixing, and fuel inspection. Data were collected using the Nordic Body Map (NBM) questionnaire to identify musculoskeletal complaints, the Rapid Entire Body Assessment (REBA) method to evaluate postural risks, and the Revised NIOSH Lifting Equation with a multitask analysis approach to determine cumulative lifting risks through the Composite Lifting Index (CLI). The findings revealed that incoming goods handling presented the highest ergonomic risk, with an NBM score of 51, a REBA score of 9 (high risk), and a CLI value of 1.065, exceeding the recommended safety threshold. Chemical mixing also demonstrated considerable postural risk with a maximum REBA score of 7, while fuel inspection showed a moderate ergonomic risk with a REBA score of 6, primarily caused by prolonged trunk flexion during manual measurement. The consistency between subjective complaints and objective assessment results confirmed the effectiveness of the integrated evaluation approach in identifying priority areas for intervention. Based on the hierarchy of risk controls, engineering interventions—including the implementation of a scissor lift pallet truck, redesign of the chemical mixing workstation with an ergonomic platform, and replacement of conventional fuel measuring tools with longer or digital measuring devices—were proposed to minimize musculoskeletal risks. The integration of NBM, REBA, and NIOSH multitask analysis provides a comprehensive ergonomic assessment framework that supports safer work systems, improves operational performance, and contributes to sustainable logistics operations by enhancing worker health, productivity, and occupational safety
