Traditionally fly ash (FA) has been used to replace cement as binder in the geopolymer concrete. The utilization of palm oil industrial waste materials known as palm oil fuel ash (POFA) and oil palm shell (OPS) that are abundantly available in South East Asia as binder and coarse aggregate in geopolymer concrete would give an added advantage in both the environmental and economic aspects. The mechanical properties of the OPS geopolymer concrete (OPSGC) through the use of POFA, FA, and OPS are investigated and reported. A total of ten OPSGC mixtures were prepared with varying percentages of POFA and FA such as 0, 10, 20, 40, and 100%. The specimens prepared with two alkaline solution to binder (AK/B) ratios of 0.35 and 0.55 were oven cured at 65°C for 48 hours. The experimental results showed that the highest compressive strength of 30 MPa was obtained for the mix with 20% replacement of FA by POFA and AK/B ratio of 0.55, which underwent oven curing. Further, the mix of up to 20% POFA (with AK/B ratio of 0.55) can be categorized as structural lightweight concrete. An increase of the POFA content beyond 20% decreases the mechanical properties, and hence this mix is recommended to be used.

The palm oil processing industry in which produces Crude Palm Oil (CPO) generally uses boilers. The combustion process with a boiler will produce pollutants in the form of particulates (dust), and gases such as NO2 and SO2. There are two palm oil processing industries in Muaro Jambi District that use different fuels: coal and oil palm shell. The purpose of this study was to determine the ratio of SO2, NO2 and particulate concentration in industries that use coal and oil palm shell.  Primary data taken in the form of concentrations of SO2, NO2 and particulates also meteorological data. Secondary data taken in the form of map area, height and diameter of the boiler, and production capacity. Sampling time is in the morning, afternoon and evening which is repeated in 3 times. The results showed that the comparison of NO2 and SO2 concentrations produced from coal-fired boilers was higher than shell-fired boilers, but both were still below the quality standard. Particulate concentrations in the palm oil processing industry that use coal-fired boilers are above the quality standard, while shell-fired boilers still meet quality standards.

The objective of this study was to investigate the effects of different species of oil palm shell (OPS) coarse aggregates on the properties of high strength lightweight concrete (HSLWC). Original and crushed OPS coarse aggregates of different species and age categories were investigated in this study. The research focused on two OPS species (duraandtenera), in which the coarse aggregates were taken from oil palm trees of the following age categories (3–5, 6–9, and 10–15 years old). The results showed that the workability and dry density of the oil palm shell concrete (OPSC) increase with an increase in age category of OPS species. The compressive strength of specimen CD3 increases significantly compared to specimen CT3 by 21.8%. The maximum achievable 28-day and 90-day compressive strength is 54 and 56 MPa, respectively, which is within the range for 10–15-year-old crushedduraOPS. The water absorption was determined to be within the range for good concrete for the different species of OPSC. In addition, the ultrasonic pulse velocity (UPV) results showed that the OPS HSLWC attain good condition at the age of 3 days.
