Abstract

This community service program aims to improve farmers' knowledge and skills in producing and applying botanical pesticides derived from lemongrass (Cymbopogon citratus) and betel leaves (Piper betle) as an environmentally friendly alternative for cocoa pest management. The program was implemented through educational outreach and hands-on training, with participant learning outcomes evaluated using pre-test and post-test assessments analyzed descriptively. The results demonstrated a high level of participant engagement throughout both the theoretical and practical sessions. Knowledge evaluation revealed a substantial improvement, with the average score increasing from 25% in the pre-test to 92% in the post-test, representing a 67-percentage-point gain. These findings indicate that the combination of lectures, group discussions, and practical demonstrations was effective in enhancing farmers' understanding of the production and application of botanical pesticides. In addition to strengthening farmers' capacities, the program introduced a safer, more affordable, and sustainable pest management alternative through the utilization of locally available natural resources.

Abstract

Integrating indigenous cultural knowledge into science education offers opportunities to develop scientific literacy through culturally meaningful learning experiences. This study aimed to develop and evaluate STEM-ethnoscience-based IPAS learning tools incorporating Gendang Loke Nggerang, a traditional Manggarai drum, as a contextual resource for teaching sound and its properties. An exploratory sequential mixed-methods design was employed, combining ethnoscience exploration, instructional product development, expert validation, preliminary trials, and quasi-experimental effectiveness testing. Qualitative data were collected through observations, interviews with five customary elders, and cultural documentation. These findings informed the development of teaching modules, learning materials, instructional videos, student worksheets, and scientific literacy assessments. The learning tools underwent expert validation and preliminary testing before implementation in a nonequivalent pretest-posttest control group design involving 343 fifth-grade students (experimental: n = 174; control: n = 169) in Manggarai Regency. Scientific literacy was examined across four dimensions: scientific context, knowledge, competence, and attitude. Expert validation supported the validity of the developed learning tools, while the experimental group demonstrated higher scientific literacy outcomes than the conventional learning group. Statistical analysis revealed a significant between-group difference (F = 11.891, p = .001), with a mean difference of 2.314 and a modest effect size (Es = 0.32). These findings suggest that integrating Gendang Loke Nggerang into STEM-ethnoscience-based IPAS learning can support elementary students’ scientific literacy while providing an educational pathway for preserving and revitalizing Manggarai cultural knowledge.

Abstract

Kampung Unggul Balitbangtan (KUB) chickens represent a promising local poultry commodity for smallholder farmers, but their development is constrained by the high cost of commercial feed. The Sahabat Tani Farmer Group in Wae Munde Preparatory Village, Kisol, East Manggarai Regency, East Nusa Tenggara, Indonesia, generates substantial quantities of cocoa pod husk waste that remain underutilized as a potential alternative feed ingredient. This community service program aims to assist the farmer group in processing fermented cocoa pod husks and other locally available feed ingredients into pelleted feed for KUB chickens. Implemented in December 2025 and involving 35 farmers, the program followed four stages: preparation, socialization, technical mentoring, and evaluation. Technical mentoring covered ration formulation, cocoa pod husk fermentation, pellet production, and pelleting machine operation. Program outcomes were assessed using a combination of quantitative methods, including pretest and posttest assessments, and qualitative methods based on direct observation. The results showed a substantial improvement in participants’ knowledge of the pellet production process, with the proportion of participants demonstrating an understanding of the procedure increasing from 20% before the program to 95% afterward (N-gain = 0.94). A cost analysis estimated the production cost of the pelleted feed at IDR 5,385 per kilogram, approximately 40% lower than the price of commercial feed. By the end of the program, participating farmers were also able to operate the pelleting machine independently. These findings suggest that hands-on technical mentoring can strengthen smallholder farmers’ capacity to convert agricultural waste and locally available feed ingredients into value-added feed products, potentially improving feed cost efficiency and supporting the sustainability of integrated crop–livestock farming systems.

Abstract

This community service program aims to strengthen the capacity of Kakor Jaya Village-Owned Enterprise (BUMDes) in Kakor Village, West Manggarai Regency, Indonesia, to produce animal feed pellets using locally available raw materials as a strategy to reduce feed costs and strengthen community-based layer poultry enterprises. The program employed an education and training approach involving interactive lectures and hands-on pellet production activities. A one-group pretest–posttest design was adopted, involving 25 participants. Data were collected using written tests and analyzed descriptively and through the Wilcoxon signed-rank test. The results demonstrated a significant improvement in participants' knowledge, with the mean pre-test score increasing from 5% to 92% on the post-test (p < 0.05). Pellets formulated from ten locally available ingredients had an estimated crude protein content of 16.2% and metabolizable energy of 2,661 kcal/kg, meeting the Indonesian National Standard (SNI) requirements for layer poultry feed. The production cost (cost of goods manufactured) was IDR 6,581/kg, representing a 30.7% reduction compared with the price of commercial feed in the local market (IDR 9,500/kg). The demonstration-based participatory training approach effectively enhanced the partners' technical competencies and created opportunities for BUMDes to establish an independent feed production business unit. This initiative is expected to contribute to sustained reductions in poultry farmers' feed costs and strengthen the economic sustainability of community-based layer poultry enterprises.

Abstract

This community service program aims to strengthen the capacity of the Sahabat Tani Farmers Group to utilize digital technology for marketing cocoa and Kampung Unggul Balitbangtan (KUB) chickens in Wae Munde Preparatory Village, East Manggarai Regency, East Nusa Tenggara, Indonesia. The program adopted a participatory approach involving socialization, mentoring, and hands-on practice. Program effectiveness was assessed using pre-test and post-test instruments, with the results analyzed descriptively. The findings indicate a substantial improvement in participants' understanding of digital marketing, with the mean score increasing from 5% on the pre-test to 93% on the post-test, representing an increase of 88 percentage points. All participants successfully created digital marketing accounts and independently uploaded their products. These findings demonstrate that the program effectively enhanced farmers' knowledge and skills in digital marketing. The initiative is expected to expand market reach, increase product value, and promote the sustainable economic empowerment of the farmers' group.
