Biological Oxygen Demand (BOD), Total Suspended Solid (TSS), and Dissolved Oxygen (DO) are indicators of water quality in water bodies. Non-polluted water has low BOD and TSS levels and high DO. Changes in these three parameters indicate a change in quality. This study aims to look at variations in the levels of BOD, TSS, and DO spatially and temporarily in Batang Arau River, Padang City in 2018. The study was conducted by observing three stations, namely in the upstream, middle, and downstream, and in the morning and evening. The results showed that BOD and TSS levels tended to increase from upstream to downstream, while DO was the opposite. The temporal variation shows that BOD and TSS levels are low in the morning and increase during the day and evening, while DO is the opposite.

Peralatan makan yang tidak hygiene dapat menyebabkan penularan penyakit. Peralatan makan dapat terbebas dari mikroorganisme melalui proses pencucian. Pencucian peralatan makan menggunakan perangkat lunak dan keras, seperti . Perangkat lunak seperti air dan larutan pencucian, sedangkan perangkat keras seperti baskom, kran air, bak pencucian dan spons. Kebiasaan meninggalkan spons dalam air cucian mengakibatkan pertumbuhan mikroorganisme. Bahan spons berpori dapat menjadi sumber kontaminasi utama, karena kontaminasi silang menularkan mikroba patogen yang berasal dari sisa makanan yang mengalami pembusukan pada sisa makanan. Penelitian ini bertujuan mengetahui jumlah angka kuman pada spon dapur yang digunakan untuk mencuci alat makan. Jenis penelitian deskriptif, pemeriksaan angka kuman pada spons berdasarkan frekuensi pemakaian dan penyimpanan. Kriteria sampel adalah spon yang digunakan rumah tangga setelah penggunaan dicuci dan dikeringkan, setelah penggunaan di cuci dan tidak dikeringkan, setelah penggunaan tidak di cuci dan dikeringkan serta spons setelah digunakan tidak dicuci dan tidak di keringkan. Sampel diambil dan ditumbuhkan pada media agar, selanjutnya di inkubasi pada incubator. Penelitian dilakukan di laboratorium Jurusan Kesehatan Lingkungan. Hasil penelitian jumlah angka kuman pada spons dapur berbeda berdasarkan  perlakuan. Spons dapur yang dicuci dan di keringkan setelah penggunaan mempunyai kandungan angka kuman lebih rendah dibandingkan dengan spons dapur yang tidak di cuci dan tidak dikeringkan setelah penggunaan. Sehingga disarankan spon setelah digunakan harus dicuci dan dikeringkan untuk memperlambat pertumbuhan bakteri serta mengganti spons cuci piring seminggu sekali.

The results of a survey conducted at the Poltekkes campus of the Ministry of Health, Padang, found that there were lots of plastic waste scattered about and had not been properly managed.

Introduction: The age group that is susceptible to disease and must get balanced nutrition to avoid stunting is the age group of infants under five years old (toddlers). Toddlers with stunting are caused by many factors, including parenting patterns, health services that can be reached by toddlers, environmental conditions where toddlers live, food consumption as food security for toddlers. The purpose of this research was to know the determinants of stunting in The West Pasaman Regency. Methods: The design of this study was a cross-sectional survey by interviewing 1,156 respondents in West Pasaman Regency which were selected using a simple randomized method. A structured questionnaire that has passed validity and reliability tests was used to collect data. Generalized Structural Equation Modeling was used to determine these determinants. Results and Discussion: The study showed that 30.8% of children under five years old in West Pasaman were stunted with the disease being diarrhea, which was 18.8%. Most of the children under five live in families with a low socioeconomic level, namely 53.9%, with a low education of 58.2%. The results of the re-specification of the model show that the variable that has the greatest indirect influence on the incidence of stunting is the diet variable (path coefficient = 0.90) compared to parenting and environment. Conclusion: Infectious diseases are a direct cause of stunting in toddlers. Parenting behavior factors, eating behavior factors, and environmental factors are indirect causes, but these factors play a very important role in causing stunting in toddlers. Preventive activities are needed, such as counseling for child growth and development, formation of caring for neighbors, a social gathering for nutritious food and pre-marital counseling which discusses parenting, eating patterns, and a sanitary environment
