Effectiveness of Lanzones (Lansium domesticum) Peelings as an Ingredient in Making Bioethanol

Abstract

INTRODUCTION

As time passes by, fossil fuel has been already depleting and cause environmental problems. Thus, by producing bioethanol from sugar containing feedstock such as fruit waste can help mitigate this problem. According to Solidum, lanzones (Lansium domesticum) peelings contains a relative amount of sugar with 1.64 g/mol which is significant for producing bioethanol. However, there are no studies have explored and tested lanzones peelings. Therefore, this study aimed to fill in the gap by testing the effectiveness of lanzones peelings as an ingredient for bioethanol production.

METHODS

A quantitative type of research was used; specifically, an experimental design which involves the fermentation and distillation of lanzones peelings to produce bioethanol. The amount used was controlled by having 200g of lanzones peelings, 1g urea, 500ml distilled water, 20g yeast and 50g sucrose. The produced bioethanol was observed physically, and two parameters such as fire duration and color were assessed; and compared to standard ethanol.

RESULTS

In assessing the bioethanol produced from lanzones peelings in terms of fire duration, it showed that the mean score of the bioethanol is 2.53 which interpreted to have lowest fire duration. Moreover, in comparing bioethanol from standard ethanol in terms of fire duration, independent t -test was used with a critical value of 2.13, where a t-value of 0.02137 was obtained which means that there is no significant difference between the bioethanol produced from lanzones peelings and standard ethanol in terms of fire duration. While, in observing the bioethanol based on its color, it was rated to have a mean score of 2.7 which interpreted to have a clear color. Thus, by using independent t-test with a critical value of 1.73; a t-value of 0.6512 was obtained which means that there is no significant difference between the bioethanol produced from lanzones peelings and standard ethanol in terms of color.

DISCUSSIONS

Hence, this study found out that bioethanol from lanzones peelings and standard ethanol shown no significant difference. This proved that lanzones (Lansium domesticum) peeling is effective in producing bioethanol.
