Abstract

Penelitian ini bertujuan untuk mengeksplorasi metode fotokatalisis menggunakan TiO2 sebagai bahan utama dalam proses penjernihan air. penelitian meliputi fotokatalisis, karakterisasi fisik dan kimia TiO2, serta pengukuran efektivitasnya dalam berbagai kondisi, seperti konsentrasi TiO2, intensitas cahaya dan waktu paparan. Selain itu, aplikasi metode ini juga di evaluasi untuk skala laboratorium maupun potensinya untuk implementasi didunia nyata. Hasil penelitian menunjukan bahwa nilai absorbansi mencerminkan seberapa banyak cahaya diserap oleh sampel, dengan absorbansi tinggi menandakan konsentrasi zat penyerap yang lebih besar atau tingkat penyerapan yang lebih tinggi. Metode fotokatalisis dengan TiO2 mampu secara efektif mengurangi kandungan kontaminan dalam air, termasuk limbah buatan. Efektivitas proses ini dipengaruhi oleh konsentrasi TiO2 dan intensitas cahaya yang digunakan. Selain itu, metode ini memiliki keunggulan berupa penggunaan energi matahari yang melimpah, biaya operasional yang rendah dan dampak lingkungan yang minimal. Dengan demikian fotokatalisis menggunakan TiO2 dapat menjadi solusi yang menjaminkan untuk mengatasi masalah pencemaran air, terutama diwilayah dengan sumber daya energi terbatas.

Abstract

This study aimed to determine, analyze and describe the concept understanding of 11th graders IPA SMA/MA on temperature and heat. This research was a qualitative descriptive study. Respondents examined 21 students who were selected based on the consideration that the class had studied the material of temperature and heat. Analysis of the data through a concept understanding test of 5 questions that were adjusted and validated by expert judgment. The results showed that the proportion of students' overall concept understanding was 54.76%. The percentage of understanding on the first item was 38.09%, the second item was 66.67%, the third item was 63.09%, the fourth item was 50%, and the fifth item was 58.33%. This shows that the understanding of the concepts of 11th grade students in natural science class in high school on temperature and heat was still low. For this reason, it is necessary to pay more attention and remediation on physics topics, especially on the concept of temperature and heat because it affects the other concepts understanding.

Abstract

This study aims to determine the results obtained from the fabrication of Fluorine Doped-Tin Oxide (FTO) glass using the Spray Pyrolysis technique. This research is experimental-laboratory. The method used in the manufacture of FTO glass is the spray pyrolysis method to deposit ordinary glass as conductive and transparent FTO glass. The tools and materials used in this research are the OMRON NE-C28 Nebulizer, Digital Ultrasonic Cleaner, Digital Balance, Magnetic Stirrer, Heating Plate (Thermo Scientific Hot Plate), Aluminum Foil, Hoses and Funnels, Statives and Clamps, Glass Substrate, Tin (II) Chloride Dihydrate (SnCl2.2H2O), Ammonium Fluoride (NH4F), Ethanol 96%. The results of the research that have been carried out show that the Ultrasonic Nebulizer is recommended as a tool for making Fluorine-doped Tin Oxide (FTO) thin films on a laboratory scale. The test results of microscopic properties (SEM and XRD), electrical properties (Current and Voltage), and resistance showed that the distance of the spray nozzle to the substrate affects the resistance value of the sample being tested. The closer the distance is given, the thickness of the thin layer increases, so that the electrical resistance decreases. However, a layer that is too thick affects the transparency of the glass. So there must be a balance between electrical resistance and transparency. The results of the optimal transparent conductive glass fabrication in this study were obtained at a distance of 11.5 cm with a temperature of 4500C in 50 minutes, which is 1286.8 Ω.
