Abstract

Manual material handling if done inappropriately can pose a risk of injury to the body, mainly in the spine, which is usually referred as musculoskeletal disorders (MSDs). Based on direct interview with warehouse workers of PT. X, it is known that in the lifting or transfering mineral water activity often causes pain in the waist and spine. This study is intended to analyze the work posture and the load level that is safe for workers to reduce the risk of MSDs, the analysis is carried out with the Recommended Weight Limit (RWL) method. From the calculation gained RWL origin = 15.36kg / 34.07lbs and destination RWL = 18.54kg / 41.12lbs. Then the origin LI value = 0.9 and destination LI = 0.8. From the results of the Lifting Index can be concluded that the risk level of this work is low and there is no problem with the lifting work. The weight of load raised does not exceed the recommended lifting limit, so there are no repairs to the work needed, but the activity must keep to get attention so the LI value can be maintained and the activity does not bear the risk of spinal injury.

Abstract

PT. X merupakan perusahaan yang bergerak di bidang fabrikasi dan manufaktur penghasil boiler yang terletak di Surabaya Jawa Timur. Sesuai dengan data laporan kecelakaan yang didokumentasikan oleh Environment Health Safety Officer (EHS) PT. X selama tahun 2015-2019 terdapat 50 kasus kecelakaan. Dari beberapa kasus yang telah terdokumentasi oleh EHS tersebut, terdapat beragam penyebab, ada beberapa kasus kecelakaan yang terjadi berulang kali dengan penyebab yang hampir sama. Bahkan telah dilakukan investigasi setelah terjadinya kecelakaan namun kecelakaan masih saja berulang. Hal ini membuktikan bahwa terdapat faktor lain yang tidak teridentifikasi atau adanya rekomendasi yang tidak efektif dari analisa yang telah dilakukan. Metode Human Factors Analysis and Classification System (HFACS) adalah suatu alat analisa kecelakaan yang digunakan untuk menganalisa suatu kecelakaan pada aspek Human Factor. Metode ini dikembangkan oleh Wiegmann dan Shappell pada tahun 2003. Metode ini didasarkan oleh model Swiss Cheese. Hasil analisis kecelakaan menggunakan metode HFACS, telah dibuktikan bahwa kecelakaan yang terjadi dikarenakan adanya kegagalan pada tindakan tidak aman yaitu kesalahan yang terjadi karena skill, kesalahan pengambilan keputusan, salah persepsi, pelanggaran yang dilakukan secara rutin, pelanggaran luar biasa. Berikutnya, kegagalan pada pre kondisi untuk tindakan tidak aman yaitu lingkungan fisik, lingkungan kerja (teknologi), crew resource management, mental yang merugikan perusahaan, fisik yang merugikan perusahaan. Selanjutnya, pada tahapan pengawasan yang membahayakan yaitu pengawasan yang tidak memadai, pengawasan yang gagal untuk mengetahui masalah, pelanggaran pengawasan. Tahapan yang terakhir adalah organisasi yaitu sumber daya manajemen, dan proses dalam organisasi. Hasil uji koefisien kontingensi terdapat asosiasi pada tahapan sumber daya manajemen dan pelanggaran pengawasan. Hasil uji kontingensi menunjukkan bahwa pada kasus ini hampir semua kegagalan mempengaruhi kegagalan di tingkat lain. Dengan demikian maka sebaiknya tidak hanya manajemen yang dikontrol, melainkan semua elemen yang berpengaruh harus tetap dikontrol sehingga dapat mencegah terjadinya kecelakaan yang disebabkan oleh human error.

Abstract

Based on data from the Health and Safety Executive, it can be concluded that as many as 90% of accidents are caused by human error. Coal mining is an industry that has a high risk of work accidents. If the mining process is not following procedures, then lives will be at stake. Human error probability assessment needs to be done because most accidents that occur in coal mining are caused by human error. HRA (Human Reliability Analysis) is part of the risk assessment process which aims to calculate the HEP value. HRA has been used in many studies to assess the risks involved in large, complex, and dangerous systems. The Success Likelihood Index Method (SLIM) is a method of analysis for human reliability. Prevention and control of human error need to be done at every stage of work. SLIM can analyze HEP at each stage of the work. SLIM aims to obtain a HEP value. To get the HEP value, we must first find the SLI (Success Likelihood Index) value. Finding the SLI value comes from a weighting questionnaire and PSF (Performance Shaping Factor) assessment that has been filled in by an expert judgment. After the HEP value is obtained, it can be seen which jobs fall into the safe risk level and which the risk cannot be accepted. Furthermore, risk reduction is carried out by making a task analysis of jobs that have a high hazard risk. Based on the research results, it can be seen the factors that cause a human error, namely unsafe conditions, unsafe actions, personal factors, and job factors. While the task that has the highest HEP value is on task 4, which is equal to 0,006932. The task with the smallest HEP value is task 1, amounting to 0,006478.

Abstract

Kru kapal merupakan sumber daya manusia yang sangat berperan penting dalam pengoperasian kapal, dari hasil observasi dan wawancara singkat didapatkan beberapa kru kapal mengalami keluhan yang mengarah pada kelelahan kerja dan terjadinya insiden tabrakan kapal karena faktor kelelahan. Penelitian ini bertujuan untuk menganalisis hubungan karakteristik individu dan beban kerja dengan kelelahan kerja pada kru kapal di PT.X. Penelitian ini berupa observasional analitik dengan pendekatan cross sectional. Populasi pada penelitian ini adalah kru kapal tunda sebanyak 133 responden dengan total sampel sebanyak 100 responden. Pengumpulan data dilakukan melalui wawancara menggunakan kuisioner IFRC untuk mengukur tingkat kelelahan subjektif dan melakukan observasi secara langsung. Analisis data pada penelitian ini yaitu analisis univariat dan multivariat yang menggunakan uji chi-square. Hasil penelitian menunjukkan bahwa karakteristik individu yang berhubungan dengan kelelahan kerja yaitu pada lama kerja dan status gizi. Beban kerja memiliki hubungan dengan kelelahan kerja. Saran bagi perusahaan yaitu adanya forum diskusi perihal evaluasi kerja, pemilihan menu diet dan monitoring, pemberian program olahraga bersama, pengawasan sistem lembur. Saran bagi pekerja yaitu tidak memaksakan diri apabila timbul gejala, melakukan istirahat dan stretching, mengkonsumsi air mineral, menjaga pola makan dan pola hidup sehat. Saran bagi penelitian selanjutnya yaitu sebagai sumber referensi untuk penelitian lebih mendalam terutama pada faktor lingkungan kerja dan beban kerja mental.

Abstract

Data derived from the Nordic Body Map (NBM) questionnaire results at PT X in March 2023 revealed that approximately 55.5% of packing workers reported experiencing extreme pain in their back and waist, attributed to manual handling tasks. This study aims to evaluate the safety of manual handling activities associated with cardboard packaging for finished products. Employing a quantitative analytic research approach with an observational method, the study includes a population and sample of 9 packing workers at PT X. Physical workload is assessed using the Cardiovascular Load method, and an ergonomic risk evaluation is conducted using the Composite Lifting Index (CLI) calculation method, considering the multitasking nature of packing work. Findings from the physical workload measurements highlight that one worker has a %CVL above 30%, placing the workload of all packing workers in the "needs improvement" classification. Additionally, CLI calculations for four units surpass the criteria, with values ≥ 3, signifying that all packing activities across units at PT X are deemed high-risk. Recommendations for improvement include adjusting the distance between the load and the body, refining lifting techniques, addressing work duration, adopting two-person lifting for heavy loads, and displaying posters with tips for manual weight lifting. Following the implementation of these proposed improvements, the results indicate that packing work at PT X is now considered safe to perform.
