Abstract

The World Health Organization reported that more than 1,000 pesticides are used worldwide to prevent pests from damaging food. According to data from the Ministry of Agriculture of the Republic of Indonesia, in 2019, the number of registered and permitted pesticide brands reached 3,207. This study aims to determine the duration of exposure, use of PPE, duration of spraying, and time of pesticide spraying on vegetable farmers in Bonto Lojong Village, Bantaeng Regency. This is quantitative research using descriptive methods. The population in this study comprised all farmers in Bonto Lojong Village, Uluere District, Bantaeng Regency, totaling 136; the sample comprised 42 farmers selected purposively. The results were obtained from questionnaires and analyzed descriptively. The results of the study showed that the number of respondents with long exposure time to farmers was 40 respondents with a percentage of 95.2%, the duration of farmer spraying was not good was 41 respondents with a percentage of 97.6%, the time of farmer spraying was good was 42 respondents with a percentage of 100%, the personal protective equipment of farmers was sufficient was 28 respondents with a percentage of 66.7%.

Abstract

This research was carried out using coagulation and flocculation methods. By using a varying pH series, namely 1 – 14 and also varying coagulant doses, namely 10 ppm, 20 ppm, 30 ppm and 40 ppm. The solution whose pH has been adjusted is then stirred using a flocculator with the addition of a coagulant for fast stirring at 100 rpm for 3 minutes, then a flocculant is added for slow stirring at 30 rpm for 3 minutes. After stirring, the turbidity of the solution was measured using a turbidimeter. The research show that pH and coagulant dosage parameters significantly influence the coagulation and flocculation process in water treatment at palm oil mills. The results indicated that the optimal pH for coagulation using aluminum sulfate (Al₂(SO₄)₃) is 7, with an effective coagulant dosage ranging from 30 ppm.
