Abstract

This study aims to determine the feasibility of using 500-ton and 1000-ton Crude Palm Oil (CPO) storage tanks in a palm oil mill. The evaluation is based on the roundshell thickness, operating temperature, and hydrostatic pressure acting on the tanks. A descriptive quantitative method was applied using primary and secondary data from PMKS Simpang Gambir. The results showed that for the 500-ton tank, the calculated roundshell thickness is 8.6 mm, the actual is 8.87 mm, and the design is 9 mm, with a hydrostatic pressure of 5.73 Pa. For the 1000-ton tank, the calculated thickness is 13.1 mm, the actual thickness is 13.8 mm, and the design thickness is 14 mm, with a hydrostatic pressure of 11.46 Pa. The corrosion rates are 0.00072 mm/month and 0.0011 mm/month, respectively. Based on the analysis, the 500-ton tank is feasible for continued use for approximately 31 years, and the 1000-ton tank for 53 years, assuming constant corrosion rates.

Abstract

Boiler Bottom Ash is a solid waste generated from the palm oil processing industry that has not been optimally utilized. In fact, this waste contains various inorganic compounds such as silica, calcium oxide, potassium oxide, and phosphorus pentoxide which have potential in agriculture, construction, and industry. Previous studies have shown that boiler Bottom Ash has a high content of oxidized silica, but its chemical composition analysis is still limited. This study aims to analyze the composition of palm oil mill boiler Bottom Ash using X-Ray Fluorescence (XRF) Spectrometer Test. The research method used is a laboratory experimental method with analysis of the mineral composition of boiler Bottom Ash using  X-Ray Fluorescence (EDXRF) Spectrometers. Samples were taken from the combustion of boiler Bottom Ash, then prepared in the form of drying and homogenization before testing. The results showed that boiler Bottom Ash contained 52.43% SiO₂, 19.98% CaO, 9.78% K₂O₅, and 7.88% P₂O₅. These results demonstrate that boiler Bottom Ash has significant potential as an industrial raw material and soil conditioner. This research is expected to support sustainable waste utilization and the circular economy concept.

Abstract

This study investigated the effectiveness of silica extracted from palm oil boiler ash as an adsorbent for improving river wastewater quality. A quantitative experimental method with a 2 × 3 factorial design was employed by varying silica adsorbent dosage (3 g and 5 g) and contact time (30, 60, and 90 minutes). River wastewater samples were analyzed before and after adsorption based on turbidity, Total Suspended Solids (TSS), pH, and iron (Fe) concentration. The results demonstrated that silica extracted from palm oil boiler ash effectively improved water quality by reducing TSS, turbidity, and Fe levels. Increasing the adsorbent dosage and extending the contact time significantly enhanced adsorption performance. The optimum treatment was achieved using 5 g of silica with a 90-minute contact time, reducing TSS from 146 to 48 mg/L, turbidity from 21.66 to 11.20 NTU, and Fe concentration from 0.2821 to 0.2221 mg/L, while maintaining pH within acceptable limits. The highest removal efficiency was observed for TSS (67.12%), followed by turbidity (48.29%) and Fe (21.27%). These findings indicate that silica derived from palm oil boiler ash is a promising, environmentally friendly, and cost-effective alternative adsorbent for wastewater treatment.
