In a food industry laboratory, some activities are at risk of causing MSDs (Muscullos Skeletal Disorder). Based on the results of general interviews addressed to 10 microbiology laboratory assistants, the results obtained by workers experiencing complaints of pain in the upper neck, lower neck, shoulders, back, right upper arm, waist, buttocks, elbows, wrists, and calves. Based on the number of complaints due to work disturbances, it is necessary to identify a more in-depth assessment of work factors and risk levels using the Rapid Entire Body Assessment (REBA) method. The results of this study based on the Nordic Body Maps questionnaire aimed at 10 microbiology laboratory assistants in the food industry laboratory, the highest value is complaints of pain in the waist, this is related to work position no. 7, namely the position of placing the Erlenmeyer that has been tested into a basket located on the floor. Then the assessment of work positions in group A = 7 and group B = 2 so that the results of the group C table assessment = 9 + 1 (load value) = 10 (including the risk level category 3 / high), so further investigation is needed.

The object of research is a place of business that produces household needs and wood-based industries. One of the products it produces is a minimalist wall shelf. In the period January – December 2021 minimalist wall shelf products are the products with the most defects. Manufacturing companies in this study have a product defect tolerance limit of 5% of the total production, but minimalist wall shelf products have a defect of 5.64%. This study aims to determine the types of defects that occur in wall shelf products, identify the causes of defects minimalist wall shelves and provide suggestions for improvements to reduce the number of future defects. In this research the method used is DMAIC. In the minimalist wall shelf production process, 4 types of defects were found. Based on the Pareto diagram, it was determined that the type of lacquer defect was not suitable to be the most dominant type of defect, namely 80.1%, it was also found that the DPMO value and sigma value on minimalist wall shelves were 14,100 and 3.69. Based on the analysis of the fishbone diagram method and Failure Mode and Effect Analysis (FMEA), it is known that the main root cause of product defects is a dirty, dusty and windy environment with an RPN (Risk Priority Number) value of 448. Analysis was carried out using the 5W + 1H approach to find improvements to overcome the problems that occur, obtained suggestions for improvements for the company, namely making work area picket schedules, making closed work areas, daily and monthly check sheet forms for maintenance of work tools, making varnish process work instructions, making training schedules for operators and submitting additional goods forms.

Analysis of Material Unavailability in the Beside Table Production Process Using Root Cause Analysis (RCA) and 5S Methods in A Furniture Company

Sakti Aji Lesmana, Novera Elisa Triana — Sun, 30 Jun 2024 00:00:00 +0000

Furniture manufacturing company, producing products such as tenban, beside cabinet, beside table. In carrying out its production, furniture companies often occur conditions of material unavailability when the production process is in progress and there is a difference between the amount of material inventory stock in the information system (computer) and the stock of materials in the warehouse. This research will identify the factors that cause material unavailability during production using the Root cause analysis (RCA) method. Several factors cause material unavailability, namely, errors in inputting material stock data, not doing physical stock-taking regularly, material moving to other parts of the shelf, material storage is not neat because there are few storage shelves and material identity labels are not yet valid, recording stock-taking is still manual, material or spare parts are lost, return material (defects) from users is placed on the same shelf as OK material and narrow warehouse space and limited storage shelves. To overcome these problems, this research provides a sustainable improvement proposal by implementing the lean thinking concept with the 5S principle in the company. It is expected that with the application of the 5S concept in this company so that the material inventory system in the warehouse is controlled optimally so that it can increase the productivity of employee performance in the company and a better change for the company.
