This study aims to determine the ability of shrimp shell waste as a biocoagulant to improve water quality and the effect of water on the parameters of pH, Conductivity, Turbidity, Silica and Fe. Contacting the coagulant with river water using a jartest at 200 rpm for 1 minute. The effective concentration of chitosan coagulant was 100 mg/l and Aluminum Sulfate which decreased more was 150 mg/l. The results showed that chitosan was able to reduce the parameters of Conductivity 51.95%, Turbidity 87.14%, Silica 58.21% and Fe 75.80%. Aluminum sulfate coagulant with a dose of 150 mg/l can reduce 39.32 % Conductivity, 65.80 % Turbidity, 38.75 % Silica, and 41.29 % Fe. The effectiveness of the shrimp shell coagulant is higher than the aluminum sulfate coagulant, it shows that the shrimp shell is able to act as a coagulant for the kelekar river water into clean water at PLTGU Indralaya.</p> Indah Pratiwi Copyright (c) 2022 KINETIKA https://jurnal.polsri.ac.id/index.php/kimia/article/view/5019 Tue, 01 Mar 2022 00:00:00 +0700 DEGRADATION OF TSS AND TDS IN LEMATANG RIVER WATER USING PALM OIL SHELLS (Elaeis Oleifera) AS A FILTRATION MEDIUM https://jurnal.polsri.ac.id/index.php/kimia/article/view/4903 <p>Palm Oil Shells (<em>Elaeis Oleifera</em>) &nbsp;is a waste from the remaining fragments of palm oil shells. The waste is made into activated carbon in two stages such as carbonization and activation using HCl. The activated carbon can reduce impurities and metals in the Lematang river water with the parameters of TSS (<em>Total Suspended Solid</em>) and TDS (<em>Total Dissolved Solid</em>). The results of the analysis showed a decrease in the levels of TSS and TDS in the raw water of the Lematang river. In the TSS test the results obtained were &nbsp;0.5 grams of activated carbon of 14,402 mg/L, for 1 gram of 16,210 mg/L, and for 1.5 grams of 20,041 mg/L. Meanwhile, the TDS test yielded 68 mg/L for 0.5 grams, 77 mg/L for 1 gram and 83 mg/L for 1.5 grams of activated carbon. So that the best adsorption occurs with the use of 0.5 grams activated carbon.</p> <p>&nbsp;</p> <p><strong>Keywords :</strong> Activated Carbon, TSS, TDS, Palm Oil Shells</p> Melati Ireng Sari Copyright (c) 2022 KINETIKA https://jurnal.polsri.ac.id/index.php/kimia/article/view/4903 Tue, 01 Mar 2022 00:00:00 +0700 THE EFFECT OF GLYCEROL CONCENTRATION ON PRODUCT DENSITY IN STEAM STRIPPING EQUIPMENT WITH RASCHING RING PACKING TYPE https://jurnal.polsri.ac.id/index.php/kimia/article/view/4904 <p><em>Stripper is a separation process between a mixture of two liquid phase substances by using a gas phase substance as a separator. In this case, glycerol and H<sub>2</sub>O are used as a mixture and steam is used as a separating agent with the aim of removing the H<sub>2</sub>O content contained in the glycerol. In the separation process, variable variations are used in the form of concentrations of glycerol and H<sub>2</sub>O, respectively, concentrations of 70 %, 80 %, and 90 % against a predetermined temperature and pressure of 140<sup>o</sup>C and 45 Psi, with the aim of knowing what the glycerol and H2O concentrations are in the separation process. can work optimally. The process that occurs is a separation process based on boiling point, where water which has a lower boiling point of 100<sup>o</sup>C will be separated from glycerol with the help of steam with a temperature of 140<sup>o</sup>C. At a variable concentration of 70 % glycerol feed with a predetermined temperature and pressure, the data obtained is that the product still contains 4 % water in the glycerol product, the results of the process still do not meet the desired product conditions, namely 99.5 %. On the other hand, with a variable concentration of 90 % glycerol, this product only contains 1 % H<sub>2</sub>O, it can be concluded that the concentration of feed glycerol on H<sub>2</sub>O is very influential in the process of eliminating H<sub>2</sub>O levels in glycerol, because the higher the concentration of glycerol on H<sub>2</sub>O the work of steam in binding H<sub>2</sub>O is lighter so that steam can strip the H<sub>2</sub>O content in the feed more maximally.</em></p> Indah Agus Setiorini, Agusdin, Muhammad Muslim Copyright (c) 2022 KINETIKA https://jurnal.polsri.ac.id/index.php/kimia/article/view/4904 Tue, 01 Mar 2022 00:00:00 +0700 EKSTRAKSI ZAT WARNA ALAMI BUNGA TELANG DENGAN METODE EKSTRAKSI SOKLETASI https://jurnal.polsri.ac.id/index.php/kimia/article/view/5020 <p>The Butterfly Pea (Clitoria ternatea) is one of the plants whose all parts have functional benefits for the human body. The<br />flower petals are reported to be useful as antioxidants, antidiabetic, antiobesity, anticancer, anti- inflammatory, antibiotic and<br />protect liver issue. One of the natural pigments that may be used as natural dyes is anthocyanin. Butterfly Pea (Clitoria<br />ternatea) is a source of blue pigment or anthocyanin. One of the ways so thatthe butterfly pea can be consumed by the public is<br />by utilizing the potential of natural pigments from the extract ofthe telang flower and some of the content in it can be done by<br />applying it as a natural food coloring. This is one of the efforts that can be done to prevent the increasing use of unsafe<br />synthetic dyes by replacing them with the manufacture of natural dyes. Anthocyanin is a natural pigment that gives blue color<br />to the butterfly pea (Clitoria ternatea). Anthocyanin extraction using soxhletation method with aquadest solvent and extraction<br />time (90, 120 and 150 minutes). This study aims to determine the best extraction time for the extraction of anthocyanins from<br />butterfly pea. The research parameters included qualitative and quantitative analysis of anthocyanins (extract yield, total<br />anthocyanin concentration, and antioxidant activity) of butterfly pea extract. From the results of the study, it was found that<br />the best condition is extract with time variation 90 minutes and 10 times circulation using aquades as a solvent with extract of<br />yield 2.36%, total of anthocyanin concentration 80.105 mg/L, and antioxidant with IC50 35.91.</p> Sofiah Copyright (c) 2022 KINETIKA https://jurnal.polsri.ac.id/index.php/kimia/article/view/5020 Tue, 01 Mar 2022 00:00:00 +0700 THE OXYGENATED DRINKING WATER https://jurnal.polsri.ac.id/index.php/kimia/article/view/5021 <p>Oxygen is an essential substance for humans, available in the air and can be freely enjoyed. At present, oxygen is not only supplied through the respiratory system, but is also supplied through the digestive system. The alternative is to supply oxygen through drinking water. In this research the design process will be carried out to produce drinking water that contains oxygen, or oxygenated drinking water. The process to make drinking water by using the membrane RO (Reverse Osmosis) and the processed by injecting oxygen using Aquatic Oxygenator. In the procesess of the RO membran and the Aquatic Oxygenator has oxygen as 100 ppm optimum in drinking water. The effect of oxygenization time and temperature on oxygen levels is the dissolved oxygen content in drinking water does not increase significantly, only in the range of 100-113.4 ppm. When the oxygenization temperature increases, the solubility of oxygen in water decreases. The effect of drinking water volume and oxygenation time on dissolved oxygen levels in water the dissolved oxygen level reaches 100 ppm, and continues with oxygenation, the measurement number does not change.</p> Erwana Dewi Copyright (c) 2022 KINETIKA https://jurnal.polsri.ac.id/index.php/kimia/article/view/5021 Tue, 01 Mar 2022 00:00:00 +0700
