ANALISA KELAYAKAN AIR DI KABUPATEN SIDOARJO MENGGUNAKAN ALAT UKUR TDS DAN PH METER BERBASIS MIKROKONTROLLER
No full textKualitas air di Daerah Metroplotian sangatlah penting untuk diteliti karena menyangkut kelayakan dan informasi terkait penggolongan air menggunakan alat berbasis teknologi. Maka perlu diadakan sebuah kelayakan atau penelitian dalam hal ini tentang kandungan pH dan TDS yang terkandung dalam air tersebut, Di mana pH tersebut mengetahui tingkat keasaman atau basa air yang dikonsumsi itu semua tergantung pada mereka, sehingga secara tidak langsung mengkonsumsi air dengan mengetahui pH air akan memberikan informasi mengenai potensi kontaminasi, karena itu menguji pH air bisa menjadi tindakan pencegahan untuk kesehatan masyarakat. Disamping kita mengetahui pH maka kita harus mengetahu tingkat kualitas air dengan TDS air – yang mana air merupakan molekul yang paling banyak ada di alam dan sebagai sumber utama kehidupan, bahkan tubuh manusia itu sendiri. Dimana TDS (Total Dissolved solid) merupakan ukuran Zat terlarut (baik itu zat organic maupun anorganic ) yang mana TDS merupakan gambaran zat terlarut dalam Part Per Million (PPM). Penelitian ini menggunakan metode eksperimental dengan data kuantitatif melalui pengambilan sampel di 14 titik se-Kabupaten Sidoarjo. Dari hasil pengujian alat ukur pengukuran TDS dan pH meter didapatkan nilai kalibrasi dari air minum baku dibawah 300 ppm sedangkan untuk air normal dibawah 500 ppm. Untuk batasan maksimal air bisa digunakan untuk kebutuhan rumah tangga dibawah 1000 ppm. 14 titik Sampel yang telah diukur, dapat disimpulkan bahwa Daerah Sedati merupakan Daerah dengan nilai ppm terbaik untuk konsumsi rumah tangga. Namun harus diolah terlebih dahulu dalam pengkonsumsiannya dikarenakan diatas 300 ppm. Sedangkan untuk 13 titik sampel daerah selain Sedati tergolong mengandung logam dan bahan-bahan campuran dalam air. Sehingga dibutuhkan pengolahan lebih lama lagi untuk bisa dikonsumsi
PHILOSOPHY OF INTEGRATED NATURAL SCIENCE LEARNING
Full text linkPhilosophically, natural sciences as a building of knowledge can study ontology (what you want to know), epistemology (how to acquire knowledge), and axiology (what is the value of knowledge). Natural Science as a building of science has properties that are closely related to natural objects. The problems that occur with natural objects are holistic. This holistic problem requires problem-solving from various disciplines, especially in the natural sciences. Based on the scope of the research above, this article aims to investigate integrated natural science learning in a philosophical review (ontology, epistemology, axiology). The qualitative method is applied in this study. Studies conducted to solve problems based on a critical and in-depth analysis of pertinent library materials are known as library research. Overviews of ontology, epistemology, and axiology state that integrated natural science learning, students are expected to be able to relate to other disciplines such as physics, astronomy, chemistry, geology, biology, technology, environment, and health and safety. This type of instruction uses natural science to present natural phenomena and events holistically and to develop students' problem-solving skills. The recommendation given is that teachers should tend to the interdisciplinary study of the natural sciences
