“…Abu terbang cangkang sawit juga dikenal memiliki sifat penyerapan yang baik terhadap polutan dari lingkungan, sehingga menjadi salah satu solusi yang tepat untuk mengatasi keberadaan arsen dalam air limbah secara efektif dengan kapasitas penyerapan yang wajar (Samad, Salleh, Zahari, & Yussof, 2019;Yusof et al, 2020). Penggunaan abu terbang cangkang sawit sebagai daur ulang produk sampingan pertanian ini secara tidak langsung dapat menyelesaikan masalah lingkungan yang berkaitan dengan masalah sistem manajemen pembuangan (Ahmad, Hameed, & Aziz, 2007;Samad et al, 2019). Bersdasarkan hal tersebut, penelitian ini bertujuan untuk menghilangkan kandungan Arsen dari air limbah tambang emas menggunakan abu terbang cangkang sawit tanpa pengolahan (raw) dengan menggunakan variasi waktu kontak sebagai standar variabel penelitian.…”

Arsenic is a dangerous compound that accumulates in nature as a result of anthropogenic activities, one of which is gold mining. Effluent originating from the remaining mining is simply abandoned even though it contains Arsenic which is above the threshold set by the Government of the Republic of Indonesia. The purpose of this study was to analyze the ability of palm shell fly ash to remove arsenic in the residual gold mining effluent. The technology applied in this study was absorption by direct mixing followed by settling and filtering. The maximum arsenic removal efficiency achieved in this study was valued at 81.98%. The longer the contact time between the palm shell fly ash and the waste sample, the less the amount of Arsenic in the waste water will be. The results of this study indicate that the method of removing arsenic from wastewater using palm shell fly ash is very effective, easy to apply and cheap in terms of the cost required.

“…It is considered superior compared to other treatment methods due to its high efficiency, low operational cost, simple process, and immunity to toxic materials (Meili et al, 2019) Various low-cost alternative adsorbents from agricultural solid waste, industrial solid waste, agricultural by-products, and biomass are used in wastewater treatment. For example, clay (Auta et al, 2012), sludge (Hu et al, 2018), rice husk biochar (Ahmad et al, 2020;Samad et al, 2019) and bagasse (Al-Mokhalelati et al, 2021), as adsorbents have been used for dye wastewater adsorption treatment. Apart from that there is solid waste from palm oil processing plants called fly ash (FA).…”

Palm kernel shell combustion waste in boiler units called fly ash (FA) is a low-cost alternative material as an adsorbent. FA contains high levels of silica (SiO2) and aluminium oxide (Al2O3). The content of both compounds is an important component as an adsorbent. FA was used to absorb methylene blue (MB) continuously from synthetic dye wastewater. The study was conducted by continuous system process optimization using Response Surface Methodology (RSM) Box-Behnken design. MB was flowed on a set of fixed-bed adsorption columns with independent variables in this study are X1 (bed height; 8, 12, 16 cm), X2 (contact time; 90, 120, 150 min) and X3 (flow rate; 2, 4, 6L/min). The dependent variables were Y1 (removal efficiency) and Y2 (adsorption capacity) with matrix design by Box-Behnken. Optimisation of MB removal in this study was obtained at X1 = 16 cm, X2 = 150 min and X3 = 2 L/min with removal efficiency of 98.45% and adsorption capacity of 0.115 mg/g. FA pores according to SEM analysis were obtained at 1-2 µm. Likewise, the results of EDX analysis showed that there were N and Cl atoms in FA after the adsorption process. This shows that FA is able to adsorb MB.

“…Large volume of POME can be a threat to the environment if released directly, therefore, effective treatment system like anaerobic digestion is recommended to reduce the organic matter in POME [12]. Meanwhile, the production of palm oil also produces a great amount of oil palm biomass waste which then incinerated to support the power plant creating ash known as palm oil fuel ash (POFA) [4,5]. The amount of POFA is massive and worrisome as every ton of crude palm oil produces around 9 tons of biomass that burnt into ash [4].…”

Anaerobic digestion is a favourable technology for the treatment of palm oil mill effluent (POME) and production of biogas. Biological treatment using an anaerobic batch reactor (ABR) augmented with palm oil fuel ash (POFA) was implemented to investigate the impact of POFA on their performances. Two ABRs are fabricated in this study: Control and POFA ABRs, where POFA ABR was operated at 2g/L of pre-treated POFA with potassium hydroxide (KOH) to increase its porosity. Both reactors are kept at room temperature and a daily feed with neutralized raw POME. Treated samples were collected daily to test for chemical oxygen demand (COD) and pH, whereas weekly tests for mixed liquor volatile suspended solids (MLVSS). Results showed that the control ABR is able to reduce up to 94.4% of COD as compared to the POFA added ABR with only 63.3% in 50 days. The addition of POFA into the anaerobic digestion resulted in lower performance in terms of COD removal efficiency by 20.5%. Economic analysis evidenced that with 85,500 m3 of POME, up to 863 tons of biomethane can be produced, showing a large amount of energy can be utilized from the anaerobic digestion of POME as an alternative energy source.
