Abstrak

Indonesia merupakan salah satu negara center market kelapa sawit terbesar di dunia sehingga perkembangan industri kelapa sawit dalam negeri tumbuh dengan sangat pesat. Namun, meningkatnya aktivitas perdagangan kelapa sawit berdampak terhadap meningkatnya limbah yang dihasilkan yaitu Palm Oil Mill Eflluent (POME). Mayoritas pabrik saat ini masih menggunakan open pond sebagai teknologi pengolahan POME, namun penggunaan teknologi ini dinilai belum efektif untuk pengolahan POME. Fotokatalitik merupakan teknologi berbasis energi sinar (UV, tampak, sinar matahari) untuk menghasilkan senyawa radikal yang dimanfaatkan sebagai agen pengoksidasi limbah POME. Katalis yang digunakan pada penelitian ini adalah ZnO. Berdasarkan hasil karakterisasi XRD dan UV-vis DRS, struktur kristal dari ZnO adalah hexagonal wurtzite dengan energi celah pita sebesar 3,22 eV. Berdasarkan hasil uji aktivitas degradasi fotokatalitik limbah POME, diperoleh bahwa penggunaan katalis ZnO dengan konsentrasi 0,5 g/L dinilai cukup efisien untuk mendegradasi kandungan organik pada limbah POME dengan persentase reduksi chemical oxygen demand (COD) mencapai 22,85%, warna 48,53% dengan konstatnta laju reaksi COD (k) adalah 2,6´10-3 menit-1.
