Industri daur ulang aluminium merupakan salah satu industri yang sedang berkembang di Indonesia. Banyaknya limbah aluminium di Indonesia memicu muncunya industri daur ulang aluminium di Kecamatan Sumobito memiliki 110 industri dan lokasi penelitian memiliki 54 industri meliputi industri besar, industri sedang, maupun industri kecil. Kegiatan daur ulang aluminium bersifat konvensional sehingga pengelolaan limbah hasil produksi belum maksimal. Keluhan kualitas air tanah dangkal yang dirasakan oleh penduduk setempat meliputi air keruh, berubah warna, berbau, menimbulkan gatal gatal dan terkadang berbau kurang sedap sehingga membuat warga menduga air tanah dangkal tercemar oleh limbah padat industri daur ulang aluminium. Tujuan penelitian ini adalah menganalisis sebaran kandungan parameter fisika meliputi TDS dan parameter kimia meliputi pH, COD, Al dan Cu.

Penelitian ini merupakan jenis penelitian survei. Teknik pengambilan sampel air sumur dangkal menggunakan Stratified Area Sampling. Populasi penelitian adalah seluruh sumur dangkal di Dusun Kedungsari. Sampel penelitian sebanyak 10 sampel air sumur dangkal, yang ditentukan dengan menggunakan systematic grid. Teknis analisis data menggunakan kuantitatif deskriptif dan deskriptif dengan acuan Peraturan Pemerintah Republik Indonesia Nomor 82 Tahun 2001.

Hasil penelitian ini menunjukkan bahwa kandungan TDS pada air tanah yang memenuhi baku mutu (<500 mg/L) berada di sampel 5, sampel 6 dan sampel 10. Parameter COD yang melebihi baku mutu (10.13 mg/L) berada di sampel 8. Hasil nilai pH menunjukkan netral. Persebaran kandungan Al masih di bawah baku mutu air yaitu (<0.06 mg/L) dan baku mutu Cu (<0.02) masing-masing menunjukkan keseluruhan sampel memenuhi baku mutu air. Nilai COD yang berada di sampel 8 melebihi baku mutu dan nilai TDS yang tinggi di area sampel menunjukkan limbah yang ditimbun memiliki kadar kandungan zat yang bervariasi setiap area sampelnya

Abstract

The aluminum recycling industry is one of the emerging industries in Indonesia. The large amount of aluminum waste in Indonesia has triggered the emergence of the aluminum recycling industry in Sumobito District, which has 110 industries, and the research site, which has 54 industries, including large, medium, and small industries. Aluminum recycling activities are conventional, so the management of production waste has not been maximized. Complaints about the quality of shallow groundwater felt by local residents include turbidity, discoloration, smell, itching, and sometimes a bad smell, leading residents to suspect that shallow groundwater is polluted by the solid waste of the aluminum recycling industry. The purpose of this study is to analyze the distribution of physical parameter content, including TDS, and chemical parameters, including pH, COD, Al, and Cu.

This research is a type of survey research. Shallow well water sampling technique using Stratified Area Sampling. The study population is the entire shallow well in Kedungsari Hamlet. The study sample consisted of 10 samples of shallow well water, which were determined using a systematic grid. Technical data analysis employs descriptive and descriptive quantitative methods in accordance with Republic of Indonesia Government Regulation No. 82 of 2001.

The results of this study showed that the TDS content in groundwater that met the quality standard (500 mg/LL) was in samples 5, 6, and 10. COD parameters that exceeded the quality standard (10.13 mg/L) were in sample 8. The result of the pH value is neutral. The distribution of Al content is still below the water quality standard, namely 0.06 mg/L, and the Cu quality standard (0.02), each showing that the entire sample meets the water quality standard. The COD value in sample 8 exceeds the quality standard, and the high TDS value in the sample area shows that the landfilled waste has a substance content that varies from sample area to sample area.
