Hidayati, Tutut (2019) Aplikasi Serbuk Dari Tongkol Jagung Tanpa Pengarangan Sebagai Adsorben Logam Besi Pada Air Sumber Menjadi Air Bersih. Sarjana thesis, Universitas Brawijaya.
Abstract
Air sumber Kabupaten Trenggalek merupakan bagian penting dari kebutuhan masyarakat sehari-hari. Jumlah air sumber di Kabupaten Trenggalek mengalami penurunan dari 361 menjadi 318 buah. Selama ini cara mengolah air untuk konsumsi kurang tepat karena direbus dengan panci yang menyebabkan komponennya terkelupas ke dalam air akibat suhu tinggi. Komponen tersebut adalah logam besi (Fe) yang memberi dampak negatif pada tubuh apabila terlalu banyak dikonsumsi. Kandungan logam besi air sumber Kabupaten Trenggalek sebesar 0,7215 ppm yang artinya melebihi standar maksimum 0,3 ppm sehingga diperlukan penurunan menggunakan adsorben. Adsorben yang digunakan berasal dari limbah pertanian salah satunya tongkol jagung. Bahan ini sangat berpotensi digunakan karena mengandung komponen kimia seperti selulosa, hemiselulosa, lignin, dan zat ekstraktif lainnya. Pembuatan adsorben memiliki beberapa metode salah satunya adalah teknik tanpa pengarangan. Adsorben dapat digunakan apabila sudah mengalami proses aktivasi. Salah satu metode untuk aktivasi adsorben adalah Liquid sonication exfoliation (LSE) yang merupakan gabungan dari sintesis nanomaterial Liquid exfoliation dan sonikasi dengan frekuensi gelombang tinggi. Tujuan penelitian ini adalah mengetahui pengaruh adsorben terhadap penurunan logam besi pada air sumber menjadi air bersih dan mengetahui karakteristik adsorben tanpa pengarangan terbaik. Penelitian menggunakan Rancangan Tersarang (Nested Design) dengan 2 faktor yaitu volume surfaktan (1 ml, 2 ml, 3 ml) dan lama sonikasi (2 jam, 4 jam, 6 jam). Ulangan dilakukan sebanyak 3 kali dan analisis datavii menggunakan sidik ragam (ANOVA) dengan tingkat kepercayaan 95% (α=0,05) dan dilanjutkan uji BNT 5%. Hasil penelitian menunjukkan bahwa lama sonikasi berpengaruh nyata terhadap semua parameter sedangkan volume sabun berpengaruh nyata pada parameter pH namun tidak berpengaruh nyata pada kadar besi dan jumlah E. coli. Perlakuan terbaik didapatkan 3 sampel yaitu pada lama sonikasi 4 jam yang tersarang di volume sabun 1 ml dengan rendemen 8,25%, kadar air 2,45%, kadar abu 3,15%, kadar besi 0,206 mg/L, jumlah E. coli 3 MPN/100 ml dan pH 6,33, pada lama sonikasi 6 jam yang tersarang di volume sabun 2 ml memiliki rendemen 8,28%, kadar air 1,99%, kadar abu 3,53%, kadar besi 0,299 mg/L, jumlah E. coli 2 MPN/100 ml dan pH 7,33 dan pada lama sonikasi 6 jam yang tersarang di volume sabun 3 ml memiliki rendemen 8,39%, kadar air 1,67%, kadar abu 3,62%, kadar besi 0,266 mg/L, jumlah E. coli 2 MPN/100 ml dan pH 7,37. Rerata ukuran partikel serbuk adsorben sebesar 16,139 µm. Adsorben tongkol jagung sesuai dengan standar SNI dan PERMENKES dari segi kadar besi dan pH namun tidak sesuai dari segi jumlah E. coli
English Abstract
Water source in Trenggalek regency is important of daily society needs. Amount of source water in Trenggalek Regency has decreased from 361 to 318 units. During this time the way to process water for consumption is not right because it is boiled with a pan which causes the components to be peeled into the water due to high temperatures. The component is ferrous metal (Fe) which has a negative impact for human when it consumed too much. The metal content of the source water of Trenggalek Regency is 0.7215 ppm which means it exceeds the maximum standard of 0.3 ppm so that a reduction is needed to use adsorbents. The adsorbent used comes from agricultural waste, one of which is corn cobs. This material has the potential to be used because it contains chemical components such as cellulose, hemicellulose, lignin, and other extractive substances. Making adsorbents has several methods one of which of the method is technique without authoring. Adsorbent can be used if that has undergone an activation process. One method for activating adsorbents using Liquid sonication exfoliation (LSE) which is a combination of synthesis of nanomaterial Liquid exfoliation and sonication with high wave frequencies. The purpose of this research was to determine the effect of adsorbents on the reduction of ferrous metals in source water into clean water and determine the characteristics of adsorbents without the best effect. The research used a Nested Design based on two factors is soap volume (1 ml, 2 ml, 3 ml) and sonication duration (2 hours, 4 hours, 6 hours). The test was performed 3 times and the data analysis used variance (ANOVA)ix with a confidence level of 95% (α = 0.05) and continued with the LSD test 5%. The results showed that the sonication duration significantly affected all parameters while the soap volume significantly affected the pH parameters but did not significantly affect the iron content and the amount of E. coli. The best treatment obtained 3 samples, namely the 4 hours sonication nested in 1 ml soap volume with a yield of 8.25%, 2.45% moisture content, 3.15% ash content, 0.206 mg/L iron content, the amount of E. coli 3 MPN/100 ml and pH 6.33, the 6 hours sonication nested in 2 ml of soap volume has a yield of 8.28%, a moisture content of 1.99%, an ash content of 3.53%, an iron content of 0.299 mg/L , the amount of E. coli 2 MPN/100 ml and pH 7.33 and the 6 hours sonication nested in 3 ml of soap volume has a yield of 8.39%, a moisture content of 1.67%, ash content of 3.62%, content iron of 0,266 mg/L, the amount of E. coli 2 MPN/100 ml and pH 7.37. The mean particle size of the adsorbent powder was 16.139 µm. Corncob adsorbent is in accordance with SNI and PERMENKES standards in terms of iron content and pH but not in terms of the amount of E. coli
