One of the essential oils with a 2,000–2,500 ton annual demand on the global market is citronella oil. It's possible that demand for citronella oil may rise by 3-5% annually. Citronella oil must meet the standards of quality before it may be sold. According to SNI, citronella oil must contain a minimum of 35% citronellal by weight. Gas chromatography-mass spectrometry (GC-MS) is the contemporary method for measuring citronellal concentrations, although GC-MS analysis is expensive both capital and operationally. Therefore, it is essential to create a method for determining the quality of citronella oil that does not rely on the use of devices that call for specialized knowledge and can be afforded by farmers. Two quantitative analytical methods to determine the amount of aldehyde in oils are the bisulfite method and the neutral sulfite method. The purpose of this study is to evaluate how these two methods are used to measure citronellal concentrations. This study aims to compare the findings of the analysis of the method used in the study with the results of the analysis using GC-MS in order to determine the most accurate and economical method for citronella farmers to use. The bisulfite and neutral sulfite methods are not thought to be practicable for application based on the research findings, thus advancements are required before they can be utilized commercially. The citronellal concentrations read from the bisulfite and neutral sulfite methods were 16% and 8% for samples with 33% citronellal concentration. As well as 8% and 11% for samples with 6% citronellal concentration. The bisulfite method was chosen as the method that has the best accuracy and is the cheapest in terms of cost. The suggestions that can be conveyed are the need for a modified tool that can meet the heating requirements of the reaction.
