Garbage is a daily waste of human activity or a natural process in a solid or semi-solid form. Composting is a decomposition process of organic waste either in aerobic or anaerobic. Many people do not understand how to recycle organic waste into compost. This research was aimed to know the effectiveness of biological waste treatment training to the knowledge, attitude, and skill enhancement of Family Welfare Programme (FWP) or ‘Pendidikan Kesejahteraan Keluarga (PKK) group in North Purwokerto health center working area. This research used Quasi-experimental with non-randomized pre-test and post-test with control group research design. Wilcoxon’s test result showed that there were differences between knowledge, attitude, and skill before and after the training of group sample with the value of p=0.014 for learning, 0.037 for the position, and 0.001 for ability. So, the test result of Wilcoxon group did not show the differences of the knowledge, attitude, and skill before (pre-test) and after (post-test) with the value of p 1.000 for learning, 0.863 for the position, and 0.527 for talent. Mann-Whitney’s test result did not show differences in the knowledge, attitude, and skill, in both group sample and group comparison with the value of p 0.072 for learning, 0.457 for the position, and 0.457 for talent. Mann-Whitney’s test result did not show differences in the knowledge, attitude, but there were differences between genius in both group sample and group comparison with the value of p 0.804 for education, 0.289 for the position, and 0.00 for ability. After this training hopefully, the PKK group can disseminate organic waste treatment skill to the other communities.
