Inovasi Bata Ringan Dengan Pemanfaatan Limbah Serat Pelepah Kelapa Sawit Terhadap Ekologi, Sosial Dan Ekonomi
Riau Province has vast oil palm plantations of 2,430,500 hectares based on BPS Indonesia (2017). The oil palm midribs waste produced 90,647,928 tons/year. The waste can be used as added material in producing CLC (Cellular Lightweight Concrete). The purpose of this study is to find the optimal CLC formulation by adding foam agent and fiber, calculating economic value, knowing the contribution to the environment and the effect of using waste on the social community. This study uses quantitative methods with descriptive types. The results of the study that the optimal job mix for CLC is 480 kg of cement; 720 kg of sand; 207.5 liters of water mortar; 44 liters of air foam agent and 2.0 liters of foam agent produce CLC that meets SNI requirements. The optimal addition of fiber in the CLC job mix is 2.5% of the weight of the cement which meets the SNI requirements. Production of fiber CLC is feasible with BCR = 1.13 > 1; NPV = Rp. 1,055,488,321; IRR = 53.76% and BEP is 3 years. CO2 emissions that can be reduced in 1 m3 CLC using diesel fuel are 74,388 kg/m3 and electricity is 80,586 kg/m3. The social impact of midrib utilization has a strong and very strong relationship with the regression model Y = 0.352 X1 + 0.659 X2 + 0.499 X3 - 1,925. The conclusion of this study is that the use of midrib waste has a positive value of increasing the quality of Cellular Lightweight Concrete (CLC) products, can provide economic value for entrepreneurs and communities, reduce greenhouse gas emissions, and have a positive effect on social and community life
