Abstract

Bottled drinking water is a source of human exposure to bromate, a disinfection by-product (DBP) with adverse health effects and carcinogenic potential. Little is known about bromate exposure levels and risk characterization, particularly in Bogor, Indonesia. The study aimed to obtain data on bromate concentrations in bottled drinking water, estimate bromate exposure levels based on individual consumption, and assess the risk characterization. Bromate exposure were calculated based on bromate concentrations and individual consumption, across five age groups. Bromate exposure and risk characterization were estimated probabilistically using Monte Carlo simulation. In this study, 37 bottled drinking water samples were collected from large and small manufacturers and retailers in Bogor and analyzed for bromate content. Bromate was detected in 30 samples, with 5 samples exceeding the Indonesian national standard of 10 µg/L. The average concentration was 6.88±8.88 μg/L. Exposure estimates indicate that, for all age groups, the average and 95th percentile values are 0.1086±0.0484 µg/kg BW/day and 0.4044 µg/kg BW/day in Bogor and 0.1492±0.2820 µg/kg BW/day and 0.5495 µg/kg BW/day in Indonesia, respectively. Values below the tolerable daily intake (TDI) limit for non-cancer risk, so the risk characterization for all age groups can be considered as safe.

Abstract

Coffee is one of the agricultural commodities in Ponorogo Regency that has high potential for development. Farmer’s limited knowledge of technology and innovation in post-harvest and coffee processing is an obstacle to improving coffee quality. This activity aims to train coffee farmers and coffee entrepreneurs in Ponorogo Regency to improve coffee quality and standards according to consumer specifications using new technologies and innovations. The training was conducted offline at the Sooko Subdistrict Office in Ponorogo Regency. There were 30 participants in the training. The activity was evaluated through tests at the beginning and end of the training to measure participants understanding during the training. A total of 10 questions in multiple choice form were given to participants. Data was collected from 23 participants. The average score of the participants increased from 3,9 to 5,9 (20% increased). The aspect that was difficult for participants to understand was related to coffee roasting.
