Abstract

Postur kerja, merupakan salah satu unsur penting dari sikap kerja yang mengandung risiko tinggi jika dilakukan dengan sikap kerja yang kurang tepat. Perlu adanya antisipasi agar tidak terjadi ganguan Musculoskeletal Disorders (MSDs). Hasil penelitian pendahuluan dengan kuesioner Nordic Body Map (NBM) pada UMKM telur asin menunjukkan keluhan dengan persentase tinggi yang dialami pekerja adalah sakit pada bagian leher atas, bahu kanan, pinggang, pantat, lutut kiri, dan lutut kanan. Keluhankeluhan ini apabila dibiarkan dalam jangka Panjang dapat menyebabkan ganguan muskuloskeletal, penyakit akibat kerja, bahkan kecelakaan kerja. Sehingga perlu dilakukan analisis postur tubuh pekerja saat melakukan aktivitas. Tujuan untuk mengetahui potensi risiko ergonomi pada UMKM telur asin “Si Emak” berdasarkan analisis postur tubuh para pekerja saat melakukan aktivitas pada proses persiapan pembuatan telur asin, dengan menggunakan metode OWAS (Ovako Working Posture Analysis System). Berdasarkan analisis postur kerja dengan menggunakan metode OWAS seluruh aktivitas masuk kategori level 4 (potensi risiko sangat tinggi), sehingga diperlukan adanya perbaikan segera postur kerja dan fasilitas kerja untuk mengurangi risiko terjadinya cedera dan atau penyakit akibat kerja. Simulasi perhitungan metode OWAS, setelah usulan penggunaan meja kerja dan kursi kerja ergonomis, diperoleh skor OWAS kategori level 1 dengan potensi risiko ergonomi rendah. Kata Kunci: UMKM, Musculoskeletal Disorders (MSDs), OWAS, Risiko ErgonomiWork posture is one of the important elements of a work attitude that contains a high risk if it is done with an inappropriate work attitude. There is a need for anticipation so that Musculoskeletal Disorders (MSDs) do not occur. The results of a preliminary study using a Nordic Body Map (NBM) questionnaire on salted egg SMEs showed that a high percentage of complaints experienced by workers were pain in the upper neck, right shoulder, waist, buttocks, left knee, and right knee. These complaints if left unchecked in the long term can cause musculoskeletal disorders, occupational diseases, and even work accidents. So it is necessary to analyze the body posture of workers when doing activities. The purpose of this study was to determine the potential ergonomic risks of salted egg SMEs "Si Emak" based on an analysis of the workers' body postures when carrying out activities in the preparation process for making salted eggs, using the OWAS (Ovako Working Posture Analysis System) method. Based on the analysis of work posture using the OWAS method, all activities are categorized as level 4 (very high risk potential), so it is necessary to immediately repair work postures and work facilities to reduce the risk of injury and or work-related diseases. The OWAS calculation simulation method, after the proposed use of ergonomic work desks and chairs, obtained an OWAS score for level 1 category with low ergonomic risk potential..Keywords: MSMEs, Musculoskeletal Disorders (MSDs), OWAS, Ergonomics Risk

Abstract

This study discusses the phenomenon of spring-back and spring-go in the bending kinematic forming using V-bending dies process and Electrolytic zinc-coated steel sheet (SECC/JIS G 3313) material. The zinc layer on the galvanized steel surface should not be damaged during the material forming process. The zinc layer on the galvanized steel sheet will affect the metal forming process. This study uses an experimental design with four input parameters, namely v-die opening L (mm), punch angle (degree), punch speed (mm/minutes), and bending force (kN). The smallest spring-back was obtained in the 4th test sample: the v-die opening of 35 mm, the punch angle of 40o, the punch speed of 30 mm/minute, and the bending force of 7.50 kN. The minor spring-back degree was 1.67o. Meanwhile, the smallest spring-go obtained in the second sample, namely the v-die opening of 30 mm, the punch angle of 50o, the punch speed of 40 mm/minute, and the bending force of 7.00 kN, the minor spring-go degree of 0.92o was obtained. These results show that the best spring-back degree for SECC/JIS G 3313 material is obtained when the bending process is performed with the v-die bending parameter of 30 mm, punch angle of 50o, punch speed of 40 mm/minute, and bending force of 7.00 kN.

Abstract

This article demonstrates that the sinker electrical discharge machining (S-EDM) method can be enhanced using SPHC (JIS G 3131) materials with a hardened surface. During S-EDM, neither contact nor a cutting force exists between the electrode and the workpiece. S-EDM is advantageous because it eliminates mechanical stress, chatter, and vibration issues with traditional milling. S-EDM is widely employed, for example, in the manufacturing of molds for automotive and aviation components. Taguchi design and signal-to-noise ratio (S/N ratio) were selected to examine the impact of the input parameter model on the material removal rate (MRR). The Taguchi approach assessed three input parameters and three experimental levels. The parameters pulse current (I), spark time (Ton), and gap voltage (Vg) were chosen to evaluate the MRR performance of the S-EDM process with the SPHC-hardened workpiece material. Copper with a diameter of 10 mm is chosen as the electrode material. This study aims to determine the optimal MRR for the chosen input variables. Results indicate that a more effective pulse current value promotes debris removal from the machining zone and stabilizes following spark release, speeding the material removal rate (MRR). In the S-EDM machining process, the pulse current value significantly affects the MRR and is one of the most significant response variables

Abstract

Workload refers to worker activities that require strength and endurance and physical energy. Thecompany under study is a manufacturing company engaged in the automotive sector in the paintingdepartment of four-wheeled vehicle production in Karawang. A related challenge is the dominance ofmanual processes in some parts of the company. The purpose of the study is to understand theworkload on each shift and see the effect of worker fatigue by calculating the amount of energyconsumption and using the CVL approach. The research results from the morning shift found that theaverage %CVL percentage in various production sections was as follows: Mixing 29.08%, Top coat27.96%, Sanding ED 25.22% and Repair 25.11%. and for the night shift as follows: Mixing 30.12%,Top coat 29.65%, Sanding ED 25.92% and Repair 22.58%. It can be seen from the results of the studythat the average CVL (%) on each shift does not cause excessive fatigue in workers. Although ingeneral the phenomenon of fatigue does not occur, according to the calculations of some workers,especially at the mixing and topcoat stages, there is a higher percentage of %CVL with an averageCVL value of 30% and requires improvement. In addition, the results of energy consumptioncalculations show that all parts are classified as work that uses low to very low energy consumption.

Abstract

XYZ is a company engaged in the paper industry, which is located in West Java. Since established in 1976, this company has produced photocopy paper in the form of reams. This company has advantages in terms of paper quality so that its products dominate the international market and the domestic market. With a very tight level of market competition, companies must continue to work optimally to continuously improve employee performance and company productivity. The purpose of this study is to plan an incentive-based employee wage system, which is suitable and in accordance with company conditions. Incentive wages are important as one of the main components to increase and maintain motivation, performance and work integrity. This research was conducted in the Finishing Department of the copy manual wrapping work unit. The method used are the Piecework method, the Halsey method, and the Rowan method. The result of this research is a comparison of the amount of wages between the wage system used by the company and the three methods of incentive pay as a company alternative. From the comparison of the three incentive wage design methods, the authors recommend the Halsey method as the best method that is able to provide benefits for both the company and for workers which we call dual mutualism. The Halsey method still guarantees a basic wage and a decent incentive wage for workers as a motivation to work faster and better.
