Abstract

Abstract – SD Negeri 12 Padang Panjang is one of the schools that has made efforts to implement the Adiwiyata program. In 2024, the school represented the city of Padang Panjang in the Adiwiyata competition at the West Sumatra provincial level; however, it did not achieve optimal results. For the 2025 Adiwiyata program, SD Negeri 12 has set a target to become the provincial representative of West Sumatra. Based on the evaluation results from 2024, it was found that the assessment indicator for Participatory-Based Environmental Activities needs improvement. One activity that can support this effort is hydroponic cultivation. A hydroponic cultivation training was conducted by 26 fifth-grade students. The training included both theoretical material and hands-on practice in cultivating green vegetables using a hydroponic system. The training was guided by two experts who are competent in the field. This training successfully increased students' knowledge of hydroponic vegetable cultivation. Moreover, over 90% of the participants demonstrated teamwork and developed a greater awareness of environmental care. This outcome is a significant contribution to supporting SD Negeri 12 Padang Panjang Barat’s efforts toward achieving Adiwiyata School status.

Abstract

Desa Talawi Mudiak menghadapi tantangan dalam pengelolaan data kependudukan. Meskipun mereka telah menyusun RPJMD 2022-2027 yang mengacu pada SDG's, pendataan yang dilakukan masih terbatas pada aspek kependudukan dan demografi. Padahal, pemutkhiran data harus mencakup 17 pilar SDg's agar dapat digunakan sebagai dasar dalam perencanaan pembangunan desa. Selain itu, keterbatasan akses internet dan kurangnya pemanfaatan teknologi informasi juga menjadi kendala pengembangan sistem informasi desa yang lebih komprehensif. Program Studi S1 Statistika hadir dalam menjembatani pencapaian beberapa pilar itu melalui pemutakhiran data hingga dilitalisasinya. Kegiatan diawali dengan pengumpulan data awal, perhitungan kerangka sampling, pelaksanaan survei, dan pemrosesan data pasca survei hingga diperoleh suatu kesimpulan yang dapat digunakan untuk pembangunan desa. Kegiatan melibatkan banyak pihak, mulai dari dosen program studi, perangkat desa, mahasiswa, dan masyarakat. Hasil yang diperoleh berupa data yang mutakhir dan sebuah buku berisikan kondisi Desa Talawi Mudiak tahun 2025.

Abstract

Nagari Pematang Panjang, located in Sijunjung Regency, is expected to become the center of banana production in Sijunjung Regency. BDB disease is one of the problems in banana cultivation in the Bunga Dahlia Farmer Group in Sijunjung. Until now, BDB has been treated with chemical pesticides or, in more severe cases, banana plants are usually destroyed. To overcome this BDB disease, the UNP community service team provided understanding through presentations on the dangers of using chemical pesticides to members of the Bunga Dahlia Farmer Group and provided the Pseudomonas fluorescens PfCasCas3-molase formula as a biocontrol agent. The presentation of materials was effective in increasing the understanding of farmer group members from 25.98% to 81.27%. The technological innovation in the form of the PfCasCas3-molase formula was successfully disseminated to the community

Abstract

Stunting remains a major public health issue in Indonesia, including in Padang Pariaman Regency, where the prevalence reached 28.3% in 2021 and declined to 19.4% in 2023. Efforts to prevent stunting require a community-based approach that utilizes local resources, one of which is the nipa palm fruit (Nypa fruticans), known for its high nutritional content and potential as functional food. This Community Service Program (PKM) aimed to enhance the knowledge and skills of Posyandu cadres in Nagari Katapiang in processing nipa fruit into nutritious and economically valuable food products. The methods included nutrition education, dissemination of information on nipa fruit potential, and training on appropriate technology for processing nipa into food products such as jam, nuggets, and meatballs. Evaluation was carried out through pre- and post-activity questionnaires. The results showed a significant increase in cadres’ knowledge of nipa’s nutritional content (from 20% to 100%) and health benefits (from 30% to 100%). Perceptions of nipa’s role in stunting prevention also increased from 25% to 95%. Furthermore, practical skills in producing nipa jam improved, where all participants who had never tried before were able to produce processed products after the training. Thus, this PKM activity successfully enhanced the knowledge and practical skills of Posyandu cadres, while demonstrating the potential of nipa fruit as a local food innovation supporting stunting prevention efforts.
