Abstract

Functional group analysis of silica gel synthesized from river sand magnetic minerals using the sol-gel method was conducted. River sand magnetic mineral samples were taken from Sompang River, Lombok. The synthesis method used is a sol-gel method with variation of HCl acid 10 M and NH4OH base 10 M. Morphological characterization using a Scanning Electron Microscope (SEM) and mineral content analysis using Energy Dispersive X-ray (EDX). The morphology of the resulting silica gel is granular, showing crystalline properties with a silica concentration of 77.99 ± 0.17 atomic percent. Silica functional groups before absorption showed three stretching vibrations, namely OH group stretching vibrations in Si-OH and H2O at an absorption wavelength of 3669.77 cm-1, Si-O stretching vibrations from siloxane (Si-O-Si) at an absorption wavelength of 2858.51 cm-1 and Si-O asymmetric stretching vibrations from silanol (Si-OH) at an absorption wavelength of 962.88 cm-1. While the results of the analysis of silica gel after absorption show that almost all samples have vibrational absorption in the range of 400-500 cm-1. Other vibrational absorptions in silica samples that have been used as water filters indicate that the bonding between nano-silica as an absorber and heavy metals is due to the magnetic properties of nano-silica.

Abstract

This study aims to determine the quality of sap water by measuring its viscosity and dielectric constant. The sample used is pure sap water and sap water mixed with coconut water. The dielectric constant was measured using the parallel plate method while the viscosity was measured using the Oswald viscometer method. Based on the measurement results, the viscosity coefficient value of pure sap water is 1.558 Poise. The value of the viscosity coefficient decreases as the concentration of the sap water decreases where the viscosity coefficient value is 1.005 Poise for the sap water with a concentration of 50% and 0.753 Poise for the sap water with a concentration of 10%. In measuring the value of the dielectric constant, the dielectric constant of pure sap water is 7.38 x 105. The dielectric constant value of the sap water decreases with the addition of coconut water which is 4.90 x 105 at a concentration of 50%, and 3.39 x 105 at a concentration 10%. Pure sap water has a higher level of viscosity than coconut water which is indicated by a higher coefficient of viscosity compared to sap water which has been mixed with coconut water so that it is able to store more electrical energy, as a result the capacitance increases and the dielectric constant also increases.

Abstract

The study has been conducted on the water quality level of the Babak River around Kebon Kongok landfill, Lombok. This research was conducted considering that water has many benefits in the daily lives of people. This research uses an experimental method by analyzing physical parameters (temperature, conductivity, pH, and total dissolved solids (TDS)), and chemical parameters in the form of heavy metal content lead (Pb), iron (Fe), manganese (Mn), and copper (Cu)). Analysis results were compared with quality standards based on Ministry of Health Regulation No. 32 of 2017 concerning water quality. Based on the study, it was found that the farther the distance of water measured from the source of pollution, the value of the physical and chemical parameters of water will be smaller. Most of the physical parameter test results show the Babak River water quality is still at the safe threshold limit but there is 1 point of river water that is polluted due to the distance that is too close to the active zone. Chemical parameters show the results of heavy metal content below the threshold limit. Analysis of the water quality shows that the water is still in good condition, which is below the threshold set by the Indonesian government.
