Abstract

Indonesia memiliki banyak sumber daya biomassa seperti limbah Tandan Kosong Kelapa Sawit (TKKS) untuk alternatif bahan bakar. Limbah padat TKKS memiliki kandungan selulosa, hemiselulosa, dan lignin yang berpotensi menghasilkan beberapa produk melalui metode pirolisis. TKKS yang digunakan dari PT. Lambang Jaya, Lampung Selatan, Indonesia. Tujuan studi ini adalah karakterisasi bio-oil yang dihasilkan dari limbah TKKS serta mengetahui faktor yang mempengaruhi produksi bio-oil. Percobaan dilakukan pada variasi temperatur 300°C, 350°C, dan 400°C, dengan biomassa TKKS berukuran 1 mm dalam reaktor pirolisis. Studi karakteristik fisika-kimia bio-oil yang diperoleh pada penelitian ini yaitu yield bio-oil, pH, densitas, viskositas, dan heating rate. Studi Karakteristik pirolisis TKKS yang diperoleh pada penelitian ini adalah yield bio-oil antara 4,32-6,49%, yield asap cair 33,03%-37,44%, yield arang 33,33%-38,35%, dan yield gas 23,53%-26,91%. Hasil pH bio-oil bersifat asam karena memiliki pH antara 3,4-3,8, densitas bio-oil 1,146-1,296 g/ml, viskositas 18,443-20,860 cP serta heating rate 4,6-6,5 °C/menit yang dikategorikan dalam jenis pirolisis lambat karena dioperasikan pada temperatur rendah dan waktu tinggal ≥ 30 menit. Pengaruh temperatur pada yield bio-oil menunjukkan semakin tinggi temperatur proses yield bio-oil yang dihasilkan semakin tinggi. Melalui studi karakteristik yang dilakukan pada pirolisis TKKS produk yang dihasilkan menarik untuk dikembangkan pemanfaatannya dengan memperhatikan parameter proses yang berpengaruh.

Abstract

The palm oil industry produces POME (Palm Oil Mill Effluent) liquid waste. POME is generally brownish, has an odor, and contains dissolved and suspended solids in the form of colloids and oil residue with a high Chemical Oxygen Demand (COD) content. Currently, the POME processing system still uses a conventional system known as the open pond system. This research aims to reduce the burden of organic materials related to removing COD levels, and color. It can solve the technical and operational obstacles of conventional processing systems. One of the extensive efforts to process POME is to develop Fenton-based photocatalytic technology, namely the Fenton-TiO2-UV method. Photocatalytic technology has several general processes involving semiconductor photocatalysts such as TiO2 and photon (UV) energy sources. In this study, the Fenton-TiO2-UV method was used with variations in the Fenton molar ratio of 1:100, 1:200, 1:300 (v/v), reaction times of 30, 60, and 90 minutes with TiO2 concentration 0.6% and uses 2 UV lamps (15 watts). This study achieved the maximum color degradation percentage at a Fenton molar ratio of 1:100 with a reaction time of 30 minutes, namely 95.28%. Meanwhile, the maximum COD degradation percentage was achieved at a Fenton molar ratio of 1:100 with a reaction time of 90 minutes, namely 98.88%.

Abstract

The main problem in the Bakung final processing place is the infiltration of leachate with high concentrations of organic and inorganic substances. Leachate from landfills is usually characterized by a foul odor, a black color, high COD values, and toxicity. This is very dangerous if it is directly flown into the ground or water body because it can pollute the environment. Therefore, it is necessary to carry out effective leachate treatment. One way to treat leachate is using Fenton method, which is a development of  advanced oxidation processes technology. The objectives of this research are to treat leachate using the Fenton method and determine the effect of the Fenton molar ratio (1:150, 1:200, 1:250) and reaction time (30, 60, 90, 120 minutes) on color and COD degradation. Optimum conditions were achieved at a Fenton molar ratio of 1:150 and a reaction time of 120 minutes, with maximum color and COD degradation percentages of 91.4% and 92.4%, respectively. The results of this research show that the Fenton method is very effective on color and COD degradation in leachate and has met the leachate water quality standards for businesses and/or final waste processing activities.
