Abstract
Kampung Inspirasi Lamongan menjadi salah satu daerah dengan kondisi air tanah/sumur yang asin dan sadah, memiliki kadar padatan terlarut (2310 mg/L), Total Coliform (39 CFU/100 mL), Fe (0,286 mg/L), Mn (0,291 mg/L), Pb (0,0131 mg/L), Al (1,2 mg/l). Untuk pemenuhan kebutuhan air bersih dan minum, dibutuhkan suatu sistem pengolahan seperti filter dengan membran reverse osmosis. Guna meningkatkan efisiensinya dan memperingan beban kerja sistem, diperlukan pre-treatment zeolit (menyisihkan TDS, Pb) dan manganese greensand (menyisihkan Fe, Mn, sebagian TC). Inilah yang membuat peneliti ingin mengimplementasikan teknologi sistem reverse osmosis dengan pre-treatment filter pasir cepat guna mengubah air tanah yang payau menjadi air bersih dan siap minum. Tujuan penelitian ini untuk mengetahui pengaruh variasi ketebalan dan ukuran butir media filter (zeolit dan manganese greensand) terhadap efisiensi penyisihan sistem RO, serta mengetahui keefektifan dan keoptimalan penggunaan media campuran zeolit dan manganese greensand sebagai pre-treatment sistem RO untuk mengubah air sumur di Kampung Inspirasi menjadi air siap minum.
Metode yang digunakan yakni kuantitatif. Pengambilan sampel air dilakukan dengan cara purposive random sampling, yang mana nantinya akan diambil sampel (secara random) air keran yang sumbernya dari sumur gali di wisata Kampung Inspirasi Lamongan. Jenis penelitian ini adalah eksperimen dengan konsep penelitian pretest-posttest. Dilakukan pengukuran parameter air minum sebelum (untuk mengetahui karakteristik air sampel) dan sesudah perlakuan (melalui proses pre-treatment dan sistem RO). Analisis data yang dilakukan yakni analisa deskriptif (berupa pembandingan hasil data dengan kualitas ataupun klasifikasi data sekunder, serta skoring). Variabel bebas yang digunakan yakni variasi penggunaan pre-treatment meliputi variasi ketebalan (cm) media campuran Zeolit:Manganese greensand (20cm:30cm dan 30cm:20cm) dan variasi ukuran butir (20 mesh dan 30 mesh).
Hasil skoring analisis deskriptif menunjukkan variasi dengan kombinasi ketebalan (Z30cm:MG20cm) memiliki poin skoring yang lebih besar, artinya penggunaan media filter campuran dengan komposisi zeolit lebih banyak berpengaruh terhadap efisiensi penyisihan yang lebih baik. Variasi dengan ukuran partikel (30 mesh) memiliki poin skoring yang lebih besar, artinya perbedaan ukuran partikel dapat mempengaruhi efisiensi penyisihan dimana, semakin kecil partikel maka semakin baik efisiensi penyisihannya. Variasi 2 sebagai variasi paling optimum untuk meningkatkan kualitas air sumur menjadi air siap minum, dengan persentase penyisihan TDS, TC, Fe, Mn, Al, Pb terbaik didapatkan secara berurut (97,82%; 100%; 78,48%; 88,46 %; 73%; 100%).
======================================================================================================================================
Kampung Inspirasi Lamongan is one of the areas with salty and hard groundwater/well water, with a total dissolved solids concentration of 2,310 mg/L, Total Coliforms (39 CFU/100 mL), Fe (0.286 mg/L), Mn (0.291 mg/L), Pb (0.0131 mg/L), and Al (1.2 mg/L). To meet the need for clean water and drinking water, a treatment system such as a reverse osmosis membrane filter is required. To improve efficiency and reduce the system’s workload, pre-treatment with zeolite (to remove TDS and Pb) and manganese greensand (to remove Fe, Mn, and some TC) is necessary. This is what motivated the researchers to implement reverse osmosis technology with rapid sand filter pre-treatment to convert brackish groundwater into clean, potable water. The objective of this study is to determine the effect of variations in the thickness and particle size of the filter media (zeolite and manganese greensand) on the removal efficiency of the RO system, as well as to assess the effectiveness and optimal use of a mixed media of zeolite and manganese greensand as pre-treatment for the RO system to convert well water in Kampung Inspirasi into potable water.
The method used was quantitative. Water sampling was conducted using purposive random sampling, in which tap water samples were collected (at random) from a dug well at the Kampung Inspirasi Lamongan tourist site. This study is an experiment using a pretest-post test design. Drinking water parameters were measured before (to determine the characteristics of the water samples) and after treatment (through the pretreatment process and the RO system). Data analysis consisted of descriptive analysis (comparing the results with quality standards or secondary data classifications, as well as scoring). The independent variables used were variations in pre-treatment, including variations in the thickness (cm) of the Zeolite:Manganese greensand mixed media (20 cm:30 cm and 30 cm:20 cm) and variations in particle size (20 mesh and 30 mesh).
The descriptive analysis scoring results show that the combination with a thickness of (Z30cm:MG20cm) has a higher score, meaning that the use of a mixed filter medium with a higher zeolite content leads to better removal efficiency. The variation in particle size (30 mesh) yielded a higher score, indicating that differences in particle size can affect removal efficiency. Variation 2 was found to be the most optimal for improving water quality to make it suitable for drinking, with the best removal percentages for TDS, TC, Fe, Mn, Al, and Pb obtained in the following order: (97.82%; 100%; 78.48%; 88.46%; 73%; 100%).
