Abstract

The presence of oil and fat in household wastewater is a significant water pollutant, as it is typically disposed of without prior treatment. Coconut husks are a promising material that can be used as a filter medium. This study aimed to evaluate the effectiveness of coconut fiber filtration in the treatment of domestic wastewater. The study employed a quasi-experimental design with pre- and post-tests but no control group. Wastewater was passed through tubs filled with coconut husk. Three different filtration tub models were tested: Model A single baffle, Model B with three baffles, and Model C with no baffle. Oil content was monitored on the 3rd, 7th, 14th, 21st, and 28th days in milligrams per liter. A Kruskal-Wallis and Mann-Whitney test was conducted to compare the results of oil content reduction between filter models. The results revealed significant differences in the mean oil content reduction among the various tub models. The percentage of oil reduction reaches 95-99%. Furthermore, the Mann-Whitney test showed no significant difference between Models A and C. However, considerable differences were identified between Models A and C, as well as between Models B and C. In conclusion, this study provides evidence of the effectiveness of coconut husk filters in reducing oil levels, with nearly the maximum observed reduction achieved by the 28th day. Additionally, it is recommended to explore the long-term sustainability and potential applications of coconut husk filters in various oil removal scenarios.

Abstract

Cooking oil is a commonly used food product in daily life, both in households and commercially, especially for frying purposes. The repeated use of cooking oil can lead to an increase in peroxide value, which may pose health risks. High peroxide values are carcinogenic and can trigger various health problems, such as elevated cholesterol levels and heart disease. One method to reduce peroxide value is by using activated carbon, such as activated carbon derived from coconut shells. This study aims to analyze the effect of contact time variations of activated carbon from coconut shells on the reduction of peroxide value in used cooking oil. The research design used was a quasi-experiment with an iodometric testing method. A total of 24 samples of used cooking oil were treated with activated carbon from coconut shells for different contact times: 20 minutes, 30 minutes, and 40 minutes. The peroxide value was then measured. The results showed that varying the contact time with activated carbon from coconut shells resulted in the following average peroxide values: 15.57 meq O2/kg, 7.57 meq O2/kg, 6.58 meq O2/kg, and 5.82 meq O2/kg. The percentage reduction in peroxide value was 0%, 51.41%, 57.06%, and 62.64%, respectively. In conclusion, the study found a significant effect of contact time variations of activated carbon from coconut shells on the reduction of peroxide value in used cooking oil, with a probability value of 0.000 < 0.05.
