Abstract

The research titled “The Effect of Palm Sap Bioethanol Composition as an Additive in Pertalite RON 90 Fuel on the Performance of a 4-Stroke Gasoline Engine” was motivated by the increasing demand for energy and the high dependence on fossil fuels, which contribute to environmental pollution. Therefore, the utilization of renewable energy has become one of the solutions that can be developed, one of which is through the use of bioethanol derived from sugar palm sap as an alternative fuel. Sugar palm sap bioethanol has a sufficiently high alcohol content, making it a potential additive in gasoline to improve combustion quality. This study aims to analyze the effect of palm sap bioethanol blend compositions in Pertalite RON 90 fuel on the exhaust gas emission characteristics of a four-stroke gasoline engine. The research method employed was an experimental approach, involving RON (Research Octane Number) testing and exhaust gas emission testing on a gasoline engine using various fuel blend variations. The tests were conducted using a gas analyzer to measure exhaust emission parameters, including carbon monoxide (CO), hydrocarbons (HC), carbon dioxide (CO₂), oxygen (O₂), and the lambda value, which indicates the air-to-fuel ratio in the combustion process. The results of the study indicate that adding palm sap bioethanol to Pertalite fuel tends to reduce CO and HC emissions, suggesting more complete combustion within the combustion chamber. Additionally, the increase in CO₂ and O₂ levels indicates improved oxidation during combustion as the percentage of bioethanol in the fuel mixture increases. The lambda values obtained are within a range close to stoichiometric conditions, indicating a better balance of the air-to-fuel ratio during the combustion process. Based on these research results, it can be concluded that sugar palm sap bioethanol has the potential to be used as a more environmentally friendly fuel additive in gasoline engines without requiring significant engine modifications. Keywords: palm sap bioethanol, Pertalite RON 90, exhaust emissions, gasoline engines, alternative fuels.

Abstract

The purpose of this research is to create an expert system using Forward Chaining to diagnose the level of learning stress in high school students using Sugeno's Fuzzy Inference System method. Data Flow Diagrams (DFD) are used to describe a data logic model or process created by the system while prototype is a development method that is used as a stage in developing applications and testing. Based on the results of research and testing of expert system design to diagnose learning stress levels in high school students using the Website-based Forward Chaining method that has been carried out by the author, several conclusions can be drawn, namely; This research succeeded in making an expert system design to diagnose the level of learning stress in high school students using the Forward Chaining method, and this study succeeded in carrying out an analysis of the results of IF THEN ELSE calculations using Forward Chaining.
