Abstract

Stunting is still a major nutritional problem faced by the Indonesian people. From the results of the previous PKM, in RW 17 Kemirimuka there were still cases of stunting 11.11% of toddlers who attended the activity. One effort that can be made to reduce the incidence of stunting is to provide functional foods such as Moringa leaves (Moringa oleifera). Moringa leaves have high vitamin C, calcium, beta-carotene, potassium and protein content, this PKM aims to provide counseling, demonstration of making functional food from Moringa leaves and anthropometric measurements in monitoring the nutritional status of toddlers at Posyandu Cempaka RW 17 Kemirimuka Village, Beji District, Depok. The 4-stage counseling method is a lecture, demonstration of making pudding from Moringa, filling out a questionnaire about the organoleptic of pudding, and measuring the anthropometry of toddlers. Based on filling out the questionnaire, it is known that making pudding from Moringa leaves is easy to do with simple and easily obtained ingredients, has a delicious taste and an attractive shape so that it is liked by toddlers. The results of anthropometric measurements show that most toddlers at Posyandu Cempaka RW 17, Kemirimuka Village, Beji District, Depok City-West Java have good (normal) nutrition and no toddler respondents were found to have poor/bad nutrition and there was no stunting. Keywords: Kemirimuka Village, Moringa, Stunting

Abstract

Agriculture in Samosir Regency has great potential but still faces land degradation, dependence on chemical fertilizers, and low utilization of organic waste. The younger generation’s knowledge of sustainable agriculture remains limited, accompanied by negative perceptions of the sector, while practice-based studies at the high school level are rare. Therefore, this study aims to implement bioecoenzim and Lacuba fertilizer training and examine students’ knowledge and perceptions of these activities. The research was conducted at SMA Negeri 1 Sitiotio, involving 41 eleventh-grade students using a one-shot case study design. Data were collected through observation, documentation, questionnaires, and knowledge tests. The results showed that the training ran effectively, as evidenced by active student participation. Students’ perceptions were in the very positive category, with an average score of 87.97, while their knowledge was in the high category, with an average score of 89.76 (Above Average). Thus, bioecoenzim and Lacuba fertilizer training has proven to have the potential to enhance knowledge and foster positive perceptions among students toward sustainable agriculture. Therefore, expanding the application of bioecoenzim and Lacuba training in other schools is important as a practical environmental education tool to support sustainable agriculture.
