Abstract

Fossil fuels are classified as non-renewable resources. On the other hand, using fossil fuels has further aggravated the impact of the environmental crisis. The development of alternative fuels that are renewable and renewable is urgently needed in line with the increasing need for fuel. One alternative energy source that can be used in the development of biofuels is Cerbera manghas oil. The catalytic cracking process with 178 g of Cerbera manghas oil can be carried out using hierarchical H-ZSM-5 as a catalyst with a mass of 0.1, 0.2, 0.3, 0.4, and 0.5g at a temperature of 250℃. Gas Chromatography Analysis–Mass Spectrometry (GC-MS) was performed on Cerbera manghas oil and biofuel products. Several hydrocarbons, C7-C12 and C16-C17, with the largest content, were identified as diesel (29.14%) and gasoline (14.08%) using a catalyst mass of 0.5g. So that the use of hierarchical H-ZSM-5 catalyst in the catalytic cracking of Cerbera manghas oil can produce hydrocarbon range gasoline.

Abstract

The residue of plastic mixture pyrolysis can be used for making paving blocks. Fibers in plastics can be used as an adhesive against other materials and can increase the strength of paving blocks. Palm oil bottom ash (POBA) was added to replace the role of cement, which has the same content as cement, i.e., silica (Si). This study aimed to see the effect of palm oil bottom ash and sand added to the residue of plastic mixture pyrolysis (i.e., PS/LDPE/PP) on the quality of paving blocks. The paving block as a test object was made by combining two materials. The residue of plastic mixture pyrolysis and LDPE plastic melt was mixed with a mass ratio of 70:30%, referred to as material I. Furthermore, palm oil bottom ash and sand were mixed with mass ratios of 100, 80, 60, 40, and 20%, referred to as material II. The ratio of ingredients I and II used was 1: 1. Testing of the quality of paving blocks includes a compressive strength test and a water absorption test. The test results showed that the ratio of PS/LDPE/PP mixture (50:25:25) had a compressive strength of 104.1 kg/cm2 or 102.08 MPa and the water absorption of 2.4% at the ratio of palm oil bottom ash and sand at 80:20%. Adding palm oil bottom ash can reduce the paving block’s compressive strength, and the residue’s LDPE content can affect water absorption because of its chemical structure properties. Therefore, less LDPE residue is needed to obtain optimal water absorption values in paving blocks and add palm oil bottom ash. Based on this compressive strength in this study and SNI 03-0691-1996, these paving blocks can be used for gardens
