Abstract

In general, inpatient health care facilities produce infectious and non-infectious waste 0.3 mᶟ / day. Non-infectious waste that is burned in an incinerator without a chimney filter, can cause particles, CO, SO2, NOx (air pollutants) and cause environmental pollution. This study aims to make a chimney filter design with a Scrubber model on an incinerator at the Public Health Center, Maospati District, Magetan Regency to reduce the amount of air pollutants emitted. This type of research is experimental research. This research designed a particle trapping device, gas by spraying water into the scrubber. The independent variable of this research was the variation of the water flow sprayed in the scrubber (3.2 liters / minute, 4 liters / minute, 5.6 liters / minute). The dependent variables of this study were particles, SO2, NOx, CO. Data collection using a digital gas detector method in the form of a UV spectrophotometer. Data were analyzed descriptively, in the form of frequency distribution, and percentage, presentation of data in a table based on air emission quality standards from thermal waste processing. The results illustrate that the use of a chimney scrubber filter with water spraying 3.2 liters / minute, 4 liters / minute, 5.6 liters / minute can reduce air pollutants, emission of SO2, CO to below the air quality standard. In addition, this tool can also reduce NOx gas and particles, but not yet below the quality standard. The conclusion from the results of this study is particulate emission air pollutants, gas SO2, CO, NOx. the incinerator can be lowered by modifying variations by spraying water 3.2 liters / minute, 4 liters / minute, 5.6 liters / minute on the chimney scrubber filter on the incinerator.

Abstract

Biogas is a renewable energy that is environmentally friendly, easy to obtain and can be updated. The technology is simple and the energy produced can be used technically, socially, and economically especially to solve energy problem in rural area. The purpose of this research was to produce a biogas stove performance with appropriate technology that can be utilized by the community. This experimental research method was designing biogas stoves with performance using 2 variations of blower (3 watt and 6 watt) and two burners that is 2 mm and 4 mm. To know the performance of biogas stove, a test is done, that is : Water boilling test. The dimension was the biogas stove, the body of the stove was made of zinc (9x38x70 cm) with two furnaces, Ø 0.5 mm iron tube distribution, 2 and 4 mm burners, 3 and 6 watt blowers, gas lighters. The results of water boilling test was stove power with fire hole Ø 2 mm blower 3 watt (0.446630 KW) and efficiency (60,54982%); fire hole Ø 2 mm blower 6 watt (0.705517 KW) and efficiency (55.86828%); fire hole Ø 4 mm blower3 watts (0.913373 KW) and efficiency (54.45203%); fire hole Ø 4 mm blower 6 watts (1.231190 KW) and efficiency (51.06681%). The performance of the biogas stove showed that the smaller the hole is Ø (2 mm), the smaller the power will be, and more efficient. The greater use of the blower (6 watts) was, the greater power will be but more inefficient. These stoves can be utilized by the community especially those with biogas. For more minimal performance, cheap, durable and easy to use needs further research. Keywords: biogas stove; digester; blower and burner
