Cokorda Keigoputra Pemayun (2021) (Keigo) and Chandra Rizqullah Triananda (2021) (Chandra) conducted their Field Work (KL) activities at PT MOYA Tangerang, a subsidiary of PT MOYA Indonesia, which is one of the largest private companies in clean water processing in Indonesia. The KL activities took place from December 27, 2023, to January 26, 2024. During the first week, the students were introduced to the company in general and learned simple water sample analysis methods. Keigo and Chandra used this time to understand the company’s situation and culture. In the following weeks, there were daily analysis activities, networking, processes, biweekly tasks, and data verification with PDAM as a cooperative partner. The third and fourth weeks were the busiest times during the KL implementation, due to water processing projects involving nanobubble and ozone equipment. They found the working atmosphere at PT MOYA Tangerang very comfortable because they were given the opportunity to participate directly in several projects, and the laboratory infrastructure facilities were excellent.
