Abstract

Rice is a staple food because it contains protein needed by the body is a source of energy. Rice that is white and shiny sometimes attracts people’s attention. Therefore, to increase buyers’ interest, many sellers add bleaching additives such as chlorine ( a chemical to kill germs) without reckoning the side effects that will be inflicted. This study examines the chlorine content in circulated rice in Bone Bolango Regency. This study used seven rice samples to be analyzed through color and precipitation tests. This research implements a mixed method in the form of qualitative as well as Iodometric and Argentometry titrations for quantitative. The results reveal that in the seven rice samples studied, there was no chlorine content due to the absence of discoloration and precipitate. It is supported by the Iodometric and Argentometric tests which show the results of chlorine levels are at 0%.

Abstract

Air, as one of the components of the environment, is the most essential requirement in supporting life. Metabolism in the bodies of living things cannot occur without air oxygen. Air can be grouped into outdoor air and indoor air. Indoor air quality dramatically affects human health because almost 90% of human life is indoors. Indoor air quality is a problem that needs attention because it will affect human health. The emergence of poor indoor air quality is generally caused by several things, namely lack of air ventilation (52%), sources of indoor pollution (16%), outdoor pollution (10%), microbes (5%), and building materials (4 %). ), others (13%). Sources of air pollution can also come from household activities, starting from the kitchen in the form of smoke. According to several studies, air pollution from kitchens contributes significantly to ARI. The novelty of this research is that it examines ambient air quality and generator emissions. The study aimed to analyze Ambient Air Quality and Generator Emissions at PT Rekso National Foods (MC Donalds) in Gorontalo City. The results showed that the surrounding air quality still met the requirements, both CO, TSP, PM10, PM 2.5 and generator emissions. However, the noise factor still does not meet the threshold standard. This study concludes that all variables still meet predetermined threshold values except for the noise variable, which exceeds the threshold value.
