Abstract

The catfish is a freshwater cultivated fish that can be found all over Indonesia. However, the problems that occur in general are usually attacks by pathogens from the Aeromonas sp group. This research aims to optimize the rapid detection of the Aeromonas sp group using PCR at the Aquaculture Technology Development Center, Cangkringan, Sleman, special region of Yogyakarta. The research was conducted by survey with purposive sampling. Isolation was carried out using two growth media, namely Tryptone Soy Agar (TSA) and Glutamate Starch Phenile (GSP). Colonies that had characteristics of the Aeromonas sp group were subjected to PCR amplification using specific primers for the Aeromonas sp group. The results of the amplification resulted in DNA that matched the target, namely 953bp, which showed that the sample belonged to the Aeromonas sp group. Based on this technique, the level of accuracy in detecting pathogens is higher than conventional methods.

Abstract

The stunting prevalence in Simpasai Village, Dompu Regency, reaches 28.5%, driven by multidimensional factors such as limited understanding of nutrition, limited access to healthcare, and low income. This Student Creativity Program (Program Kreativitas Mahasiswa/PKM) aims to address these issues through an integrated approach that combines digital technology innovation and the empowerment of local food potential. The implementation method includes two main interventions. First, the introduction and implementation of the "Si-Cegah Stunting" Application, a digital platform for monitoring the nutritional status of toddlers in real-time by the cadres of the LILI Posyandu (Integrated Health Service Post), which accelerates early detection and intervention responses. Second, the empowerment of the "Mawar" Housewives Group through product innovation in the form of fortified moringa leaf cookies, rich in iron and protein, as a specific nutrition intervention strategy based on local wisdom. The implementation results show that the application successfully digitized anthropometric records, improved data accuracy, and facilitated cross-sectoral collaboration. Meanwhile, intensive training and mentoring for the housewives successfully enhanced production capacity and opened up business opportunities, contributing to increased income and access to nutritious food. This program concludes that the convergence between utilizing technology for health surveillance and optimizing local resources for nutritional intervention creates a comprehensive and sustainable stunting management model. This synergy not only addresses the root causes of nutritional problems but also empowers the community's economy, thus aligning with efforts to accelerate stunting reduction and achieve the Sustainable Development Goals (SDGs).
