“…The dust from the gamelan production process is high enough so that it can affect the health of workers if allowed to continue. Dust will be a problem for the health of workers so it is necessary to provide an immediate solution [11], [12]. Therefore it is necessary to have an ergonomic intervention as a solution to this problem.…”

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.

“…Air pollution has been identified as a major environmental problem associated with respiratory disease and reduced life expectancy. 1 One indicator of reduced air quality is the presence of particulate matter (PM) which is commonly found around industrial activities, such as the cement industry. 1 , 2 In China, the second-largest source emitter of air pollution, a cement factory contributed about 15% CO 2 and 14% of PM <2.5 μm (PM 2.5 ).…”

Background. Cement plants generate particulate matter (PM) across processes from raw material preparation to packaging. The presence of total suspended particulates (TSP) coming out of the stack causes a high accumulation of dust in residential areas. Human exposure to TSP could affect human health and wellbeing. Objectives. The present study aims to evaluate concentrations of TSP and to estimate the health risks of TSP exposure through the inhalation pathway in communities surrounding a private cement industry in Maros regency, Indonesia. Methods. Total suspended particulates were collected using a high-volume air sampler (HVAS) at five locations. Samples were taken by grab sampling for 24 hours. The SCREEN3 program was used to view the maximum range and distribution of pollutants based on the geographical, stack profiles and meteorological factors in the study area. Hazard quotient (HQ) was used to estimate non-carcinogenic risks of TSP in surrounding communities. Results. Total suspended particulate concentrations were measured with a maximum value of 133.24 μg/m3 and a minimum value of 18.48 μg/m3. This maximum value exceeds the minimum acceptable level from Canadian National Ambient Air Quality Objectives (C-NAAQOs). The non-carcinogenic risks from the inhalation pathway were low except for location 3 (HQ>1) across all locations. Conclusions. The cement plant may significantly contribute to total TSP concentrations in air and may potentially have adverse effects on human health. Communities near the cement plant are vulnerable to TSP exposure and measures are needed to reduce TSP in Maros regency, Indonesia. Participant Consent. Obtained Ethics Approval. This study was approved by the Health Research Ethics Committee of Hasanuddin University with protocol number 28920093022. Competing Interests. The authors declare no competing financial interests.

“…Evaluation and control of dust hazards deserve particular attention in order to decrease the exposure level. Based on previous research studies, workers have reported respiratory discomfort due to the poor air quality in the foundry work environment [3,4]. The presence of particulate matter (PM) in the air may cause serious health problems.…”

Foundry workers are exposed to numerous health hazards, which includes respirable dust exposure as a prominent health issue. Apart from metallic dust, respirable crystalline silica (RCS) is generated during the fettling operation, which is very hazardous and a leading cause for silicosis. Evaluation and control of such hazards deserve particular attention in order to reduce the dust exposure level upto the permissible limits. In present study, an attempt was made to propose a low-cost design control intervention utilizing sensor based intelligence (ATmega328P microcontroller and an optical dust-sensor, SHARP GP2Y1010AU0F) for monitoring the dust exposure, followed by virtual ergonomics approach in CATIAV5R20. The proposed device was tested under several operating conditions. The results indicated that the prototype was sensitive to dust, having higher average dust density values under the dust haze weather condition (arithmetic mean (AM): 0.2590 mg/m3, geometric mean (GM): 0.2350 mg/m3) and fettling work-section (AM: 0.2550 mg/m3, GM: 0.2164 mg/m3) respectively, as compared to other conditions. Also, biomechanics analysis yielded the spine compression values lesser than the recommended limits, validating that the proposed fettling booth models could be considered as suggestive engineering control measures in conjunction with the designed prototype, so as to minimize the respirable dust exposure levels.
