This community service activity aimed to increase the knowledge and awareness of Micro, Small, and Medium Enterprises (MSME) workers regarding the importance of hygiene and sanitation in food production processes. The program was carried out at Kripik Tempe “Tri Manunggal” in Karangsari Village, Jatiyoso Subdistrict, Karanganyar Regency, using a participatory and educational approach. Participants received training that included material presentation, handwashing simulation, and the use of personal protective equipment (PPE). Evaluation was conducted through pre-tests and post-tests to measure knowledge improvement. Descriptive analysis showed a significant increase in the average score from 20% (pre-test) to 90% (post-test). In addition to cognitive gains, participants also showed behavioral changes and a willingness to apply and promote hygiene practices within their communities. The program was supported by providing sanitation facilities such as handwashing stations and PPE kits. In conclusion, hygiene and sanitation education is highly effective in fostering clean working behavior among food-sector MSME and is suitable for replication in similar community.

In rehandling activities In coal processing activities, mechanical tools such as crushers are needed to obtain production results in accordance with the company's desired targets according to the crusher target, therefore in processing it is necessary to carry out precise calculations, so that the ability of the tool (crusher) and know what things greatly affect the production processing process, so that it can be used optimally and has a high efficiency value for optimal production. Therefore, it is necessary to evaluate the results of the crusher production and the productivity of the support unit during rehandling activities in achieving the production target at ROM Port Area 2 in order to adjust the ability of the tool and other influencing factors with the crusher production target desired by the company. Actual rehandling productivity meets the crusher production plan target of 1100tph. Productivity in each zone with DT wheel 10, namely zone H there are 2 of 120,620 tph and 154,935 tph, zone L of 135,351 tph, zone M of 138,313 tph, zone I of 189,709 tph. And constraints on the crusher during a month that also affect obstacles in rehandling include schedule time with a total time of 176.72 hours, breakdown time with a total time of 4.84 hours, unscheduled time with a total time of 154.62 hours.
