Ramdhan, Mohammad (2019) Optimasi Campuran Biosorben Kulit Kakao, Ampas Kopi Dan Cangkang Telur Terhadap Penurunan Total Krom Dan Sulfida Limbah Cair Penyamakan Kulit. Sarjana thesis, Universitas Brawijaya.
Abstract
Industri penyamakan kulit merupakan salah satu industri tertua didunia dan sedang berkembang pesat di Indonesia. Akan tetapi, proses produksi industri tersebut menghasilkan limbah cair yang berbahaya. Limbah cair industri penyamakan kulit mengandung total krom dan sulfida yang tinggi. Salah satu metode alternatif pengolahan limbah cair yaitu biosorpsi. Biosorben dari limbah pertanian yang paling berpotensi untuk di kembangkan di Indonesia diantaranya kulit kakao, ampas kopi dan cangkang telur karena memiliki ketersediaan yang melimpah dan memiliki karakteristik dan gugus fungsional yang berbeda-beda. Tujuan dari penelitian ini untuk menentukan rasio pencampuran biosorben kulit kakao, ampas kopi dan cangkang telur yang optimal dan mengidentifikasi gugus fungsional yang berperan dalam penurunan total krom dan sulfida. Rancangan penelitian menggunakan Response Surface Methodology (RSM) model Box-Behnken dengan 14 Jenis variansi perlakuan. Pelaksanaan penelitian dimulai dari pembuatan biosorben, pengambilan sampel, proses biosorpsi, pengujian total krom dan sulfida, pengolahan data, validasi data dan pengujian FTIR. Berdasarkan hasil penelitian diperoleh kondisi optimum campuran biosorben kulit kakao, ampas kopi dan cangkang telur pada rasio 1,03 : 1,72 : 2,8 dengan penurunan total krom sebesar 80% dan penurunan sulfida sebesar 82%. Berdasarkan hasil analisa FTIR campuran biosorben kulit kakao, ampas kopi dan cangkang telur terdapat gugus fungsi O–H, C–H, C=O, C=C dan C–O yang berperan aktif dalam penyerapan ion total krom dan sulfida limbah cair penyamakan kulit
English Abstract
The leather tanning indusrty is one of the oldest industries in the world and it’s growing rapidly in Indonesia. However, the industrial production process produces hazardous wastewater. The tannery Industry wastewater has a high total chromium and sulfide. One alternative method of processing wastewater is biosorption. Biosorbents from agricultural waste is the most potential to be developed in Indonesia such as cacao pod husk, spent ground coffee, and eggshell because abudant availability, have different characteristics and functional groups. This study aims to determine the optimal mixture of cacao pod husk, spent ground coffee, and eggshell biosorbent and identify functional groups that play a role in decreasing total chromium and sulfide. The research design used Response Surface Methodology (RSM) Box-Behnken model with 14 types of treatment variances. The research began with biosorbent production, wastewater sampling, biosorption processing, total chromium and sulfide testing, data processing, and data validation. Also, the optimum proportion tested by FTIR to determine functional groups that play an important role in decreasing total chromium and sulfide. Based on the results, the optimum condition for the mixture of cacao pod husk, spent ground coffee, and eggshell biosorbents in ratio 1.03:1.72:2.8 with removal total chromium by 80% and sulfide 82%. Based on the result of FTIR analysis, the functional group of O–H, C–H, C=O, C=C and C–O play an active role in the absorption of total chromium and sulfide ions found in tanning wastewater
