Abstract

Paving block is a composition of building materials made from a mixture of portlandcement or similar hydraulic adhesives, which are components of building materials that are very commonly used. But besides that, the dependence on the use of cement as an adhesive for Paving Blocks is still high. Therefore, the solution taken is to use waste plastic, Styrofoam, and used oil as materials for making Paving Blocks. Based on the results of data processing, it can be concluded that the manufacture of paving blocks using a mixture of plastic, used oil, and styrofoam has several stages, namely the stages of preparing tools and materials, taking and collecting plastic waste, used oil , and styrofoam, heating stages, mixing stages, the printing stage, the release stage and the drying stage, and the laboratory testing stage. This study uses 6 comparisons of mixed materials. The results of the trial of making paving blocks using a good mixture of plastic waste and used oil, namely with a composition of 67%: 33% with an average compressive strength of 63.2 MPa and water absorption capacity of 2.4% entered into quality A used for roads while paving blocks with plastic waste materials, used oil, and styrofoam have the best compressive strength value, which is 26.0 MPa with a composition of 40%:50%:10% and the absorption power obtained is 5.2%. B quality is used for parking lots.

Abstract

Palm oil shell is a large palm oil processing wastes, reaching 60% of oil production. Utilization of oil palm shell biomass can be used for biopellets and biooil. Cellulose, hemicellulose, and lignin components in biomass are factors that affect the quantity and quality of biooil produced. This study aims to make grade 2 biooil from oil palm shells with the pyrolysis method, to determine the physical properties of biooil produced from oil palm shell pyrolysis. Palm oil shells can be converted into grade 2 biooil by pyrolysis method. Samples that are close to the parameters of the physical properties of biooil are actually obtained with a burning time of 1 hour and have a density of 1.0391 gr/cm with a pH of 2.91 and a grade 2 biooil with a density of 1.0038 gr/cm with a pH of 2.87. Analysis of grade 2 biooil with GC-MS identified 1.15 Pentadecanediol (C16H32O2) 37.603%; n-Hexadecanoic acid (C16H32O2) 18.923%; phenol (C6H6O) 28.961%.
