Abstract

Akhir-akhir ini cincin batu permata terutama jenis akik ramai di pasaran. Produksi batu permata ini biasanya dilakukan pada industri kecil atau industri rumah tangga. Permasalahan yang terjadi pada proses produksi di industri kecil ini adalah sikap kerja yang tidak alamiah seperti duduk jongkok dan bersila, menggunakan gerinda tangan tanpa menggunakan alat pengaman/pelindung diri, menggosok batu permata dengan cara manual menggunakan tangan sehingga produktivitas tidak optimal dan menyebabkan banyak keluhan pada para pekerja. Untuk menurunkan keluhan yang ada dan meningkatkan produktivitas kerja para perajin perlu dilakukan penerapan ergonomi toal pada industri kecil produksi batu permata. Penelitian ini dilakukan secara eksperimen dengan rancangan group within – treatment (sama subyek) terhadap 12 perajin permata di Desa Subagan, Karangasem, Bali. Subjek diberikan dua perlakuan yaitu P0 melakukan pekerjaan seperti biasa seperti sebelumnya dan P1 melakukan pekerjaan dengan cara baru yang sudah mendapat intervensi ergonomi. Beban kerja diukur dari denyut nadi kerja sedangkan produktivitas kerja diukur dengan jumlah produksi dibagi beban kerja dan waktu kerjanya. Hasil penelitian menunjukkan bahwa ada perbedaan yang signifikan antara P0 dan P1 (p<0,05). Antara P0 dan P1 terjadi penurunan beban kerja sebesar 27,4% dan peningkatan produktivitas kerja sebesar 422,80%. Disimpulkan bahwa penerapan ergonomi total pada perajin batu permata di Karangasem Bali dapat menurunkan beban kerja dan meningkatkan produktivitas kerja.

Abstract

The production process of making gamelan in Tihingan Village still uses the traditional way, namely using prapen with an open flame both for the melting process and in the formation process. This causes the workload of craftsmen to be quite heavy due to exposure to radiant heat and dust. The results of microclimate measurement of the work environment obtained an average dry temperature of 33.2oC, an average wet temperature of 24oC. The average ball temperature was 33oC, WBGT 26.3oC and the mean humidity (RH) was 59.0%. The average light intensity at work reaches 319.2 lux. The average temperature of the furnace at low heat is 340oC and during the combustion process it reaches 860 oC. The results of measurements of air quality in the workplace include levels of NO2 17.00 µg /m3 (increased by 112.50%), SO2 5.33 µg/m3 (increased by 45.23%), CO 407.16 µg/m3 (increased by 217, 99%), oxidants (Ox) 61.00 µg/m3 (increased by 1.67%) and dust 48.50 µg/m3 (increased by 125.58%). The mean pulse of the nguwad workers reached 125.81±1.35 beats/minutes (including heavy workload). This causes the productivity of craftsmen to be low due to the increase in musculoskeletal disorders and craftsmen fatigue. To overcome this condition, the workings of the craftsmen need to be improved immediately through the application of appropriate technology in the form of furnace repair so that the flames and dust produced can be removed from the workplace, then exposure to hot air and combustion dust will no longer expose the craftsmen.

Abstract

The garments businesses in Bali grow quickly in line with the growth of tourism industry. These are proven by presence of many garment businesses in big scale investment with hundreds of workers or small -scale investments of home industries. However, the level of awareness and the failure of the business managers to seek for comfort, health, and safety for their workers remains very low. One of many problems that important in garment business for the workers in flat iron is musculoskeletal disorder. Generally, the working position is in the standing position for long time, and the hot temperature of environment resulted in the flat iron radiation. Workers that use flat iron work 9 hours per day including the lunch break and 7 day a weak, except for the big holidays or when there is less order. They start working at 08.00 a.m. until 17.00 p.m. with lunch break at 12.00 until 13.00 p.m. Arrangement for the working time and the break time, holiday, working shifts, are one of the many aspects in organization that needs to be paid attention because by arranging the working time, it may make them comfortable, safe, healthy, so it can increase the work productivity. Increasing the working time will cause the accumulating fatigues and in turn, it will decrease the productivity. Therefore, to solve that problems, this research has been done experimentally by arranging the working time, namely by providing 10 minute-breaks every two hours of working time while drinking tea. This research was conducted to 12 female workers who used flat iron in “A” garment, of Tabanan Regency, Bali, with treatment by subject design. The indicated workload was measured by heart rate with pulse meter. Musculoskeletal disorder was predicted by Nordic Body Map questionnaire. Data were analyzed by t test on 5% significant. The result of analysis showed that there was a decrease of workloads and the subjective disorders significantly before and after treatment as well as the increase of the working productivity significantly (p<0,05).
