Abstract

This study applies an integrated multi-media approach (river water–sediment–shallow groundwater) to assess heavy metal contamination (Pb, Cu, Cd, Fe, and Hg) along the Batang Ayumi River within the influence zone of the active Batu Bola landfill, a setting rarely evaluated in an integrated manner. Samples were collected from four stations (upstream control to downstream) and analyzed using atomic absorption spectrophotometry (AAS). Fe and Pb emerged as the most responsive indicators of landfill influence: Fe increased downstream and was reflected by accumulation in sediments, while Pb showed greater mobility in river water and nearby wells, suggesting transfer from surface transport to shallow groundwater. Cu peaked upstream, whereas Cd and Hg were relatively stable but detectable across media. Although concentrations remained below applicable standards, the spatial patterns indicate persistent environmental pressure that could intensify without improved controls. By integrating evidence across water, sediment, and groundwater, this study clarifies plausible heavy-metal migration pathways from landfill leachate—surface-water transport, sediment retention, and infiltration toward shallow aquifers—supporting targeted leachate management and long-term multi-media monitoring.

Abstract

Stunting masih menjadi permasalahan gizi kronis yang berdampak jangka panjang terhadap kualitas sumber daya manusia di Indonesia. Upaya pencegahan stunting tidak hanya memerlukan intervensi medis, tetapi juga perubahan perilaku gizi keluarga melalui edukasi dan pemberdayaan masyarakat. Penelitian ini bertujuan untuk menganalisis pengaruh program edukasi Kuliah Kerja Nyata (KKN) terhadap perubahan perilaku gizi keluarga dalam pencegahan stunting di wilayah pedesaan. Metode penelitian yang digunakan adalah kuasi-eksperimen dengan desain pretest-posttest tanpa kelompok kontrol. Sampel terdiri atas 40 keluarga yang memiliki balita dan mengikuti program edukasi gizi oleh mahasiswa KKN selama empat minggu. Instrumen penelitian berupa kuesioner perilaku gizi yang mencakup aspek pengetahuan, sikap, dan praktik gizi. Data dianalisis menggunakan uji paired sample t-test. Hasil penelitian menunjukkan adanya peningkatan signifikan pada skor pengetahuan (p0,05), sikap (p0,05), dan praktik gizi keluarga (p0,05) setelah pelaksanaan program. Kegiatan KKN berbasis edukasi gizi terbukti efektif dalam meningkatkan kesadaran dan perilaku gizi keluarga, terutama dalam pemilihan bahan makanan bergizi, penerapan pola makan seimbang, serta praktik pemberian makanan tambahan pada balita. Dengan demikian, program edukasi KKN berperan penting sebagai bentuk intervensi berbasis masyarakat untuk mendukung upaya pencegahan stunting secara berkelanjutan di tingkat keluarga dan komunitas.

Abstract

This study was motivated by the limited use of household activities as a medium for mathematics learning for early childhood children, although daily activities have significant potential to introduce numeracy concepts in a concrete and meaningful manner. The study aimed to analyze the relationship between a contextual learning model based on housewives’ activities and the mathematical literacy skills of early childhood children in Bandar Hapinis Village. This research employed a quantitative approach using a pre-experimental design with a one-group pretest-posttest design. The research sample consisted of 25 housewives and 25 children aged 4–6 years. Data collection was conducted through observation, and the data were analyzed using the Pearson correlation test. The findings revealed that the implementation of the contextual learning model was categorized as good, with an average observation score of 17.92. Children’s mathematical literacy skills improved from an average pretest score of 58.83 to a posttest score of 82.27. The Pearson correlation result (0.687; significance 0.000 < 0.05) indicated a positive and significant relationship between contextual learning and children’s mathematical literacy skills. However, future studies should involve larger samples and stronger research designs.

Abstract

Stunting masih menjadi permasalahan gizi kronis yang signifikan di Indonesia, termasuk di wilayah pinggiran kota seperti Desa Gunung Hasahatan, Kota Padangsidimpuan. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis faktor-faktor sosial, budaya, dan ekonomi yang memengaruhi pola asuh dan praktik gizi balita di wilayah tersebut. Dengan pendekatan kualitatif deskriptif dan metode studi kasus, data dikumpulkan melalui wawancara mendalam, observasi partisipatif, dan dokumentasi terhadap ibu balita, kader Posyandu, petugas gizi, serta tokoh masyarakat. Hasil penelitian menunjukkan bahwa rendahnya literasi gizi ibu, pengaruh budaya lokal, keterbatasan ekonomi, serta kurang optimalnya intervensi lembaga kesehatan berkontribusi signifikan terhadap tingginya kasus stunting. Praktik pemberian makan yang tidak sesuai kebutuhan mikronutrien, kepercayaan tradisional yang menormalisasi tubuh kurus, dan minimnya keterlibatan edukatif menjadi kendala utama. Intervensi edukasi berbasis komunitas oleh perguruan tinggi menunjukkan dampak positif dalam meningkatkan kesadaran gizi masyarakat. Penelitian ini merekomendasikan strategi penanggulangan stunting berbasis multisektor, partisipatif, dan kontekstual dengan mengintegrasikan pendekatan budaya, peningkatan literasi gizi, serta pemberdayaan ekonomi keluarga. Temuan ini diharapkan dapat menjadi dasar perumusan kebijakan lokal yang lebih adaptif dan berkelanjutan dalam penanganan stunting di wilayah pinggiran kota.
