Abstract

This community service project aims to improve the implementation of Occupational Health and Safety (OHS) at the small-scale bag manufacturing business, Rangganesvi, in Malang, Indonesia. The purpose was to identify occupational hazards and implement appropriate interventions based on Indonesian OHS laws and regulations. Field observations and interviews revealed various risks, including mechanical, physical, electrical, chemical, ergonomic, and psychosocial hazards, affecting workers' health and safety. Specific issues included poor ventilation, inadequate lighting, lack of personal protective equipment (PPE), and poor ergonomic practices. Interventions included safety training, hazard identification, PPE provision, and improvement of work environment design. The results indicated that awareness of OHS principles was initially low, but the introduction of ENASE (Effective, Comfortable, Safe, Healthy, Efficient) work systems and safety briefings led to measurable improvements in work conditions. The study concludes that small enterprises require tailored, participatory safety management approaches to prevent workplace accidents and improve employee wellbeing. Systematic hazard assessments and alignment with Indonesian OHS law (UU No. 1 Tahun 1970) are essential to establish a sustainable safety culture in informal industries.

Abstract

The implementation of Learning Vector Quantization (LVQ) to classify the ripeness of oil palm fruits is investigated in this study. In addition, this study provides a comprehensive set of procedures ranging from data collection and pre-processing to training and testing of the LVQ model, and finally, the proposed method has been validated by testing it on previously unseen data. Three feature extraction methods, specifically Gray-Level Co-occurrence Matrix (GLCM), Hue, Saturation, and Value (HSV), and t-Distributed Stochastic Neighbor Embedding (t-SNE), were assessed for their performance. The results show that the chosen feature extraction method strongly influences the classification performance. The accuracy of the model employing t-SNE features is notably the highest at 50%, indicating its efficacy in identifying the ripeness level of palm fruits by extracting pertinent features. On the other hand, the GLCM feature has a 40% accuracy in the test data, suggesting that although it captures information on texture, it may not comprehensively encapsulate ripeness characteristics. Additionally, the HSV feature achieves an accuracy of 45%, which is less precise than that of t-SNE. To conclude, this study elucidates the appropriateness of various feature extraction techniques in categorizing the degree of ripeness in palm fruits. The t-SNE feature extraction model stands out as the most efficient option, exhibiting greater precision in comparison to other methodologies.

Ms. Tuminah's Carangmas MSME is a Carangmas home industry located in Sidorahayu Village, Wagir District, Malang Regency. Ms. Tuminah's Carangmas MSME produces Carangmas. MSME Carangmas Mrs. Tuminah was established in 2019, to date employs 4 employees. Where the process of making carangmas is still manual and requires a long time during the process. To fulfill an order of 1500-5000 carangmas in one order, it takes up to 3 (three) days in the manufacturing process. Because at this time the MSMEs are still using simple tools, the time needed for the production process is still fairly long. Moreover, there is still the possibility of work accidents in some of the manufacturing processes. The methodology for designing the Crangmas Making Machine begins by surveying the field to observe the production process, collecting and processing working time data to be used as a support to analyze the time, size, and position of body movements, which are carried out by workers in carrying out work activities with old tools., collecting and processing work data with old conditions, designing Carngmas Manufacturing Machines. The data sources used are primary data and secondary data. The data used in assisting the design of the Carangmas Making Machine include qualitative data (interviews), and anthropometric data. From the results of the design of the workings of the carangmas making machine, namely an electric motor with a speed of 1200 rpm as the driving force for the Mixing and Printing tool.

Abstract

The stage of separating the coffee bean shell is one of the important processes in coffee processing. The separation of the coffee bean husks at the Ashari Jaya MSME uses two different machines so this separation process is carried out in two processes because during the process of separating the coffee bean husks in machine 1 it is still mixed with the peeled skin so it requires machine 2 to make these dry coffee beans clean from remaining skin mixture. The purpose of this machine design is to combine two machines into one, making it easier for workers to operate the machine, as well as more ergonomic in terms of size. With the dry coffee bean huller machine, it is hoped that it can increase the productivity of peeling dry coffee beans as well as relieve workers from the workload and reduce the risk of work accidents. The research method in designing this semi-automatic dry coffee bean huller machine includes conducting a survey of MSMEs processing Ashari Jaya coffee beans, identifying problems with these MSMEs, and formulating problems obtained from data collection. Furthermore, the data obtained were processed using the time and motion study method as a method of designing a machine operator work system accompanied by a data similarity test, and a data sufficiency test to determine the standard time and standard output. From the results of this study, it can be seen that testing using the old machine obtained a standard time of 2.8 minutes/kg and testing using a new machine obtained a standard time of 11.8 minutes/kg, then the increase in production productivity is 0.06 kg/second and the percentage increase in standard output by 88% with a productivity ratio of 1: 2.2

Abstract

Home Industry Convection Bag "Rangganesvi" is a Home Industry that produces various types of bags. Workers carry out the production process manually using makeshift work facilities that are not good because these workers sit hunched on the floor without a base for 8 hours of work. This problem is related to work postures that are not ergonomic. This can lead to complaints of Musculoskeletal Disorders (MSDs) which consist of bones and skeletal muscles that are conscious muscles. With these complaints, a Nordic Body Map (NBM) Questionnaire was filled out for 11 workers to know the body parts of the workers who felt sick while doing work at the work station. It was found that the most dominant body part of the risk of Musculoskeletal Disorders (MSDs) is the back. This is analyzed using the Rapid Upper Limb Assessment (RULA) method. The final score obtained for the cloth cutting process activity with the posture of sitting on the floor and doing cloth cutting manually gets a score = 6 and is at a risk level of 3 which indicates that further investigation is needed and changes are needed as soon as possible by using a Cloth Cutting Machine which gets a score = 3 and is at risk level 2. Thus it can reduce the risk of Musculoskeletal Disorders (MSDs)
