Abstract

Berkembangnya teknologi dan ilmu pengetahuan, membuat suatu perusahaan harus berkembang dan beradaptasi agar dapat bersaing di pasarnya. Namun, secanggih apapun zaman dapat dipastikan manusia tetap memiliki kontribusi yang krusial karena masih terdapat beberapa kriteria pekerjaan yang harus dilakukan secara manual mengandalkan kekuatan fisik manusia, keterbatasan ruang gerak, maupun akselerasi pekerja. Namun, risiko bahaya terhadap pekerja juga meningkat membuat SDM menjadi faktor penting di sebuah perusahan. Penerapan ilmu ergonomi mampu menciptakan sistem kerja yang aman untuk para pekerja. Sistem kerja yang tidak ergonomis memiliki potensi besar risiko Musculoskeletal Disorders (MSDs). Penelitian dilakukan pada empat operator produksi pada aktivitas manual feeding raw material PT. X yang menunjukkan indikasi keluhan MSDs berdasarkan hasil kuesioner Nordic Body Map yang diberikan. Keempat operator tersebut memiliki indikasi keluhan sakit pada pinggang atau lower back pain. Pemodelan 3D dengan motion capture digunakan untuk menganalisis aktivitas dan didapatkan hasil rekam gerak tiap operator bertotal 400 frame. Analisis biomekanika untuk menghitung beban L5/S1, perhitungan energy expenditure, dan penilaian Rapid Entire Body Assessment (REBA) dilakukan untuk mendapatkan beban kerja dan tingkat risiko dari aktivitas operator produksi. Pada kondisi eksisting, semua operator memiliki beban pada L5/S1 lebih dari 6400 N dengan kategori major risk. Selaras dengan hasil penilaian REBA, postur kerja tiap operator memiliki nilai REBA pada rentang 4-13 yang artinya perlu dilakukan perbaikan segera. Hasil analisis menunjukkan postur kerja yang baik adalah disaat tubuh pekerja membentuk sudut mendekati 90o terhadap garis horizontal. Setelah dilakukan perbaikan, energy expenditure keempat operator berhasil dikurangkan secara berurut sebesar 37%, 38%, 38%, dan 12%.

The development of technology and science, makes a company must develop and adapt in order to compete in its market. However, no matter how sophisticated the times are, it is certain that humans still have a crucial contribution because there are still several criteria of work that must be done manually relying on human physical strength, limited space for movement, and worker acceleration. However, the risk of harm to workers also increases, making human resources an important factor in a company. The application of ergonomics can create a safe work system for workers. Work systems that are not ergonomic have a large potential risk of Musculoskeletal Disorders (MSDs). The research was conducted on four production operators in the manual feeding raw material activity of PT X who showed indications of MSDs complaints based on the results of the Nordic Body Map questionnaire. The four operators have indications of lower back pain. 3D modeling with motion capture was used to analyze the activity and obtained motion records for each operator totaling 400 frames. Biomechanical analysis to calculate L5/S1 load, energy expenditure calculation, and Rapid Entire Body Assessment (REBA) were conducted to obtain the workload and risk level of the production operators' activities. In the existing condition, all operators have a load on L5/S1 of more than 6400 N with a major risk category. In line with the results of the REBA assessment, the work posture of each operator has a REBA value in the range of 4-13 which means that immediate improvements need to be made. The results of the analysis show that a good working posture is when the worker's body forms an angle close to 90o to the horizontal line. After the improvement, the energy expenditure of the four operators was reduced by 37%, 38%, 38%, and 12% respectively.
