Abstract

Introduction: Ensuring access to clean and safe drinking water is crucial, especially in flood-prone regions where the water quality in dug wells can deteriorate due to various physicochemical factors. This research was aimed to measure the effectiveness of natural materials in improving water quality based on physicochemical parameters and to compare water quality before and after treatment in Astambul Subdistrict of Banjar Regency, South Kalimantan Province. Methods: The study involved a survey of 192 private boreholes and dug wells across five villages in the Astambul Subdistrict, with 30 samples selected for detailed analysis. Key physicochemical parameters analyzed included total dissolved solids (TDS), dissolved oxygen (DO), turbidity, and total suspended solids (TSS). TDS, with a standard limit of 50 mg/L, served as a primary water quality indicator. DO, essential for gauging water oxygenation, and was measured as it results from photosynthesis and atmospheric absorption. Turbidity was assessed using a turbidimeter to determine water clarity, and a UV-vis Spectrophotometer 2008 was utilized to measure levels of iron (Fe) and mangasene (Mn). Results and Discussion: The findings demonstrated that coconut shells, husks, and water hyacinths improved water quality across physical and chemical parameters. Statistical analysis using t-tests showed improvements in these parameters after treatment. For example, DO levels increased in multiple villages, with the highest percentage in Kaliukan Village (59.2%) and decreases in turbidity and TSS. Conclusion: The study concluded that coconut shells, husks, and water hyacinths have potential to enhance physicochemical quality of water.

Abstract

Salah satu upaya higiene dan sanitasi makanan yang harus dilaksanakan oleh Instalasi Gizi yaitu menjaga kualitas kebersihan peralatan makanan mengingat peralatan sebagai sumber kontaminan makanan. Tujuan penelitian untuk mengetahui efektivitas metode pencucian peralatan makan terhadap penurunan angka kuman. Metode penelitian menggunakan desain true eksperimental. Rancangan penelitian yang digunakan adalah posttest only control group desain dan teknik pengambilan sampel adalah acak sederhana. Instrumen dalam penelitian yaitu seperangkat alat untuk percobaan, pengambilan dan pemeriksaan sampel. Variabel bebas dalam penelitian ini adalah metode pencucian pada peralatan makan dengan menggunakan metode A, B dan C sedangkan variabel terikat adalah angka kuman peralatan makan. Hasil penelitian menunjukkan angka kuman peralatan makan di Rumah Sakit Jiwa Sambang Lihum melebihi standar/tidak memenuhi syarat kecuali pada metode pencucian A semuanya memenuhi syarat yaitu dibawah 100 koloni/cm2 permukaan alat. Kesimpulan dari penelitian ini adalah ada perbedaan yang signifikan terhadap ketiga metode pencucian tersebut yang ditunjukan dengan nilai p value sebesar 0,027. Perlu dilakukan penelitian lanjutan pada proses pencucian dengan menambahkan proses sterilisasi.

Abstract

Malnutrition constributes to underlying cause of death of Indonesian underfives chilren. One of the consequences of malnutrition in long time period is growth failure that is stunting. Low education of mother is important risk factor for stunting. The aimed of study was to confirm wether maternal education for child stunting in Banjarbaru. Crossectional design was implied to and 51 children aged 6-23 months old were enrolled in study, which run for three months in the year 2013. Maternal education was calculated by year complete of schooling and stunting was by z-score of height for age. Statistical test for data analysis used chi-square test with 95% confidence interval (CI). Result showed that there a significant association (pKeywords: children 6-23 months of age, maternal education, stuntingABSTRAKKekurangan gizi menjadi salah satu penyebab kematian balita di Indonesia. Konsekuensi kurang zat gizi dalam jangka waktu lama adalah gagal tumbuh. Pendidikan ibu yang rendah merupakan factor risiko yang penting pada pertumbuhan anak. Tujuan penelitian adalah mengkaji risiko tingkat pendidikan ibu dengan kejadian stunting pada anak berumur 6-23 bulan. Desain penelitian adalah cross-sectional dengan besar sampel 51 anak berumur 6-23 bulan. Penelitian dilakukan selama 3 bulan di Cempaka, Banjarbaru tahun 2013. Tingkat pendidikan ibu ditentukan dengan pendidikan formal yang telah diselesaikan, stunting ditentukan dengan indikator z-score untuk panjang badan menurut umur. Data dianalisis dengan uji chi-square dengan confidance interval (CI) 95%. Pada penelitian ini ditemukan hubungan yang bermakna (pKata kunci: bawah dua tahun, tingkat pendidikan ibu, stunting
