Abstract

Sanggar Peni in Krebet Hamlet produces various wooden batik crafts such as key chains, wooden spoons and forks, masks, statues, mirror frames, and other souvenirs. However, there are production layout issues that cause time wastage and lower efficiency. One example is the distance between production processes, such as from cutting to engraving which takes 86,520 seconds with a distance of 41 meters, and from engraving to sanding which takes 23,312 seconds with the same distance. Research using lean manufacturing methods, Current Value Stream Mapping (CVSM), Block Plan, and OMH revealed the time required at various stages of production. The cutting process required a total of 391.25 seconds (320 seconds for operation and 71.25 seconds for transportation), engraving 2,018.38 seconds (2,000 seconds for operation and 18.38 seconds for transportation), and sanding 763 seconds (752 seconds for operation and 10.83 seconds for transportation). The total material handling cost reaches Rp16,214 per day. Based on Block Plan analysis, the highest R-Score value of 0.95 indicates optimal efficiency in the arrangement of production facilities, which is expected to reduce time wastage and increase productivity on demand.

Abstract

The production process of wooden batik at Sanggar Peni Krebet plays an important role in preserving local culture and supporting the economy, but workers face the risk of musculoskeletal disorders due to unergonomic working positions when performing activities such as sculpting, sanding, batik making, and boiling . Based on the NBM questionnaire on 15 workers, the highest complaints were found in the right upper arm (100%), right wrist (100%), and waist (88%). Research using the RULA and REBA methods revealed the batik activity to have a very high risk (RULA 7, REBA 11), requiring immediate improvement, while boiling had a medium to high risk (RULA 5, REBA 9), requiring investigation and change. The EFD emphasizes the importance of designing batik boiling stoves, chairs and tables that consider height according to the worker's body size, ergonomic working positions, and comfortable strainer handles. Tool development should focus on improving comfort, safety and efficiency, with design adjustments to support workers' postures and use lightweight yet strong materials. The application of these elements is expected to improve safety and productivity in the batik industry.
