Abstract

Cooking oil is one of basic needs among human that develop year by year. The potency of waste-cooking oil utilization is unique study section. The purpose was reused waste-cooking oil become the ready matter by adsorption method. Effectiveness test adsorben between bentonite and rice husk ash (RHA) on used cooking oil was carried out in three stages which consist of characterization raw material, adsorption process, and feasibility test. The characterization stage was figured out in some parameters, clarity level (absorbance), density, moisture content, acid value, and peroxide number, metal element (Cu, Fe, and Pb). One-way analysis of variance (ANOVA) was performed between additive weight and adsoprtion time. Acid and peroxide number was tested by titrimetric method whereas the clarity level was examined with UV-Vis Spectrometry based on absorbance value. The optimum condition was the addition 55 gram bentonite for 40 minute treatment with absorbance, acid, and peroxide number 0,227; 0,443 mg/g; 0,986 mg/g respectively. The oil regeneration characteristics have meet the SNI (3741:2013) requirements however peroxide number still in limitance. Further, the study was required to develop edible oil properties toward the materials and adsorption method modification.

Abstract

Leachate contains a high organic content, which can cause environmental pollution. The organic content in leachate can be removed through bioremediation using microbial fuel cell (MFC) systems to remediate pollutants and generate bioelectricity. Organic matter is important to the MFC process as both a substrate and a nutrient source. This study investigated the effects of glucose and sodium phosphate buffer nourishment on BOD, COD, and TSS removal and bioelectricity generation. This study used leachate as a substrate and a graphite rod with a surface area of about 32.98 cm2 as an electrode. The reactor uses plastic blocks with a 3L capacity. Bioremediation using MFC was conducted in batch experiments under aerobic conditions for 20 days at various glucose dosages. All monitoring processes were conducted in real time using the internet of things (IoT). The glucose variations used were 10% (b/v) and 20% (b/v) with the addition of a sodium phosphate buffer. The removal efficiencies of BOD, COD, and TSS with 10% glucose and sodium phosphate buffer addition were 86.05%, 81.84%, and 75.50%, respectively. The highest electrical voltage was observed upon the addition of 20% glucose and sodium phosphate buffer at about 900 mV.
