Abstract

Volume limbah sebagai hasil sisa produksi semakin bertambah banyak sebanding dengan pesatnya pertumbuhan industri. Salah satu limbah industri adalah fenol. Fenol merupakan limbah organik dan biasanya dibuang ke lingkungan air. Salah satu cara mengolah limbah adalah melalui proses adsorpsi dengan karbon aktif. Alternatif penerapan teknologi adsorpsi dengan karbon aktif dipilih karena permukaan karbon aktif luas, kemampuan adsorpsi besar, mudah diaplikasikan dan biaya yang diperlukan relatif murah. Limbah kayu dalam sampah kota dimanfaatkan dengan mengubah fungsi bahan menjadi karbon aktif sebagai adsorben untuk penyisihan fenol. Limbah kayu yang dipakai berasal dari industri mebel yaitu limbah kayu jati, merbau dan kamper. Analisis spektrofotometri dilakukan setelah fenol kontak dengan karbon aktif. Penelitian ini membandingkan penambahan variasi dosis karbon aktif dari limbah kayu dan komersial serta variasi konsentrasi limbah fenol buatan. Konsentrasi fenol yang digunakan adalah 6,41 mg/L, 4,27 mg/L dan 2,57 mg/L. Adsorpsi fenol dilakukan dengan sistem batch. Pembuatan karbon aktif melalui tiga proses yaitu; dehidrasi, aktivasi dan karbonisasi. Karbon aktif limbah kayu diuji karakteristiknya yaitu kadar arang ± 35%, kadar air ± 4,5%, kadar abu ± 2% dan daya serap terhadap larutan I₂ di atas 20%. Sedangkan pola bentuk partikel dan struktur mikro diuji dengan SEM. Prosentase penyisihan fenol oleh karbon aktif mencapai 99%. Peningkatan konsentrasi fenol dan dosis karbon aktif meningkatkan prosentase penyisihan fenol. Tetapi karbon aktif yang diuji tidak memperlihatkan perbedaan yang nyata. Sedangkan aplikasi model isotherm karbon aktif dari limbah kayu dan komersial adalah isotherm Freundlich. Daya adsorpsi terbesar berasal dari karbon aktif limbah kayu jati. Persamaan isotherm Freundlich adalah x/m = 0,2095C¹⁻⁸ dengan kapasitas adsorpsi sebesar 0,2095 mg/mg.

Waste volume production is increasing as industrial growth. One of industrial waste is phenol. As organic waste, phenol is thrown into the water body. One way to treat this waste is by using adsorption with activated carbon. The alternative of adsorption technology application with activated carbon was chosen because of its wide surface area, high adsorption capacity, economical and easy availability. Wood waste that has been changed to be activated carbon can be used to be adsorbent to remove phenol. The research is using wood waste from furniture industrial, for example jati, merbau and kamper. Spectrophotometer analysis was done after phenol contact with activated carbon. This research compared the addition dose of activated carbon wood waste and commercial and also the concentration variation of artificial phenol. Phenol adsorption was done with batch system. Phenol concentration which has been used were 6.41 mg/L, 4.27 mg/L and 2.57 mg/L. Activated carbon was made during three processes; dehydration, activation and carbonization. Characteristics of activated carbon were evaluated as carbon concentration ± 35%, water concentration ± 4.5%, dust concentration ± 2% and capability to adsorb I₂ over than 20%. While particle pattern and microstructure were evaluated using SEM. Removal percentage of phenol with activated carbon is achieved 99%. Concentration of phenol and activated carbon can be increased as increasing removal percentage of phenol. But experimented activated carbon did not show significant difference. Isotherm models application of activated carbon from wood waste and commercial is isotherm Freundlich. The largest of adsorption capability is jati wood waste activated carbon. The equation of isotherm Freundlich is x/m = 0.2095C¹·⁸⁴¹³ with adsorption capability is 0.2095 mg/mg.
