Abstract

The synthesis of the portable adsorbent material CMC-Fe3O4-Chitosan-TiO2 begins by inserting the CMC-Chitosan mixture into the leaching solution. Next, concentrated NaOH and 3% CaCl2 were added, then decanted and dried at room temperature. After that, the composite was coated with TiO2 and then dried in an oven at a temperature below 100 oC. The success of the synthesis was indicated by the presence of specific absorption in FT-IR. 3429 cm-1 hydroxyl group, 2926 cm-1 for the CH/CH3 group, 1631 cm-1 for the carbonyl group (C=O), 1642 cm-1 which is the CH/CH3 group, as well as ) and ( at 400-600 cm-1. In addition, the different surface morphology of the material formed from its basic components is based on SEM characterization sails. Adsorption test results for Hg (II) metal ions were 53% while dyes were 38% with a time of 40 minutes. This research is good for handling watermaster

Abstract

Kesehatan dalam kehidupan manusia merupakan hal yang terpenting terutama bagi anak usia dini yang dapat dicapai dengan menerapkan perilaku hidup bersih dan sehat dengan cara menjaga kebersihan diri, dapat dilakukan dengan cara mencuci tangan menggunakan sabun. langkah awal untuk merubah sikap siswa agar menerapkan perilaku hidup bersih dan sehat sehingga mewujudkan sekolah yang sehat adalah di sekolah. Tujuan pengabdian ini untuk meningkatkan pengetahuan siswa tentang cara mencuci tangan menggunakan sabun dengan benar. Metode yang digunakan meliputi ceramah, tanya jawab dan pemberian leaflet tentang PHBS. Sebelum diberikan penyuluhan siswa diberikan pre-test kemudian dilakukan penyuluhan dan dilanjutkan post-test terhadap peserta, kemudian dilanjutkan praktek cuci tangan. Hasil kegiatan menunjukkan adanya perbedaan signifikan pengetahuan sebelum dan sesudah penyuluhan, dengan nilai p-value = 0,000 < α = 0,05, yang mengindikasikan bahwa penyuluhan PHBS berperan positif dapat meningkatkan pemahaman PHBS melalui cuci tangan menggunakan sabun pada siswa dengan benar. Kesimpulannya, pengetahuan PHBS efektif dalam meningkatkan kesadaran siswa mengenai pentingnya cuci tangan menggunakan sabun supaya terhindar dari penyakit infeksi

Abstract

Many Indonesian residents have difficulty obtaining clean water, especially people who live in coastal areas. Those who live there can only consume brackish water which is considered to have side effects on health due to the excessive calcium content. This research offers a simple method, namely adsorption using abundant raw materials, namely rice husk ash from agricultural waste resulting from burning rice husks. Using husks directly has less effectiveness, so it needs to go through additional processes such as removing impurities and modifying the structure. This research aims to reduce calcium levels in brackish water using silica that has been modified from rice husk ash. The process of making adsorbents is carried out by sieving, heating, filtering, washing to obtain silica, then modifying and optimizing important parameters until its application to brackish water. The difference between pre-modified and modified silica can be seen in the characterization with FTRI at wave numbers from 470 cm-1 to 430 cm-1 1, namely deeper bending vibrations, which are also clarified by the surface condition with more structured pores seen in the SEM results. The modified silica works optimally at a mass of 0.4 grams, pH 7.5, contact time of 40 minutes and concentration of 50 ppm. It has an adsorption capacity of 3.2 mg/g and follows the Langmuir isotherm pattern.
