Abstract Background This study aims to calculate the intake of foods rich in CYP2E1 enzymes and glutathione to increase toluene detoxification. Methods The research design used was a cross sectional method. The research location is printing industry in Surabaya, East Java. The number of respondents was 30 workers of the printing industry. The calculated variables included body weight, work duration (years), work frequency per week (days), average workday (hours) of the respondent and benzene concentration. After all variables were obtained, respiration rate and carcinogenic detox benzene food intake per respondent were determined. Results All respondents who were at work showed benzene concentrations below the threshold value (TLV). Foods containing CYP2E1 enzyme included beef liver, salmon and fish oil while food with glutathione included grapes, avocados and asparagus. Conclusion Adequacy levels of CYP2E1 enzymes and glutathione are different and varied. The effective dose required by each respondent depends on body weight, length of work, and toluene concentration at work. In sum, the greater the toluene concentration, the greater the dietary needs which are rich in enzymes and CYP2E1 glutathione. Each respondent can choose benzene detox food depending on their needs and appetite.

This study aims to utilize Clushtering Algorithm in grouping the number of people who have health complaints with the K-means algorithm in Indonesia. The source of this research data was collected based on the documents of the provincial population which had health complaints produced by the National Statistics Agency. The data used in this study are data from 2013-2017 consisting of 34 provinces. The method used in this research is K-means Algorithm. Data will be processed by clushtering in 3 clushter, namely clusther high health complaints, clusther moderate and low health complaints. Centroid data for high population level clusters 37.48, Centroid data for moderate population level clusters 27.08, and Centroid data for low population level clusters 14.89. So that obtained an assessment based on the population index that has health complaints with 7 provinces of high health complaints, namely Central Java, Yogyakarta, Bali, West Nusa Tenggara, East Nusa Tenggara, South Kalimantan, Gorontalo, 18 provinces of moderate health complaints, and 9 other provinces including low health complaints. This can be an input to the government to give more attention to residents in each region who have high health complaints through improving public health services so that the Indonesian population becomes healthier without health complaints.Keywords: data mining, health complaints, clustering, K-means, Indonesian residents
