Abstract

Water is a very important basic need for human life. The fulfillment of water needs in Beru Village is highly dependent on groundwater, which is extracted by digging wells. Due to the community’s dependence on the availability of well water, it is very important to monitor and assess groundwater quality in Beru Village. The lack of related research makes this research very important to do. The purpose of this study is to analyze groundwater quality in Beru Village, Jereweh District, West Sumbawa Regency. Water quality test parameters use the parameters include pH, temperature, conductivity, TDS, and DO. The average values of each parameter sequentially are 7.07; 30.18OC; 752.71 µS/cm; 377.91 mg/L; and 4.83 mg/L. On average, the quality of groundwater is classified as good and meets the required quality standards. Based on pollution index calculation, water quality based on parameters pH (PIj=0.92) and TDS (PIj=0.497) is classified as good, while water quality based on parameters temperature (PIj=1.079) and DO (PIj=1.162) is categorized as slightly polluted but relatively safe to use for sanitary hygiene needs.

Abstract

Oil is one of the most popular media for the ozonation process compared to other media such as water or saline methods or direct exposure to blood. Ozonated oil has an advantage over other ozone therapy methods because ozonated oil has an antiseptic activity that is several hundred times higher than ozonated saline. Sumbawa oil is one of the local wisdom products of the Sumbawa tribal community, which is generally used as medicine or massage therapy to heal injuries such as broken bones, tendonitis, bruises, back pain and treatment of various skin wounds. An ozonation process can be carried out to increase the ability of Sumbawa oil to regenerate skin and repair tissue. Ozonation uses a Double Dielectric Barrier Discharge (DDBD) plasma reactor. The DDBD Plasma Reactor is a reactor that can produce ozone gas with very high purity. Pure ozone gas is very well applied in the medical world. This research aims to increase the peroxide levels in Sumbawa oil by ozonation using a Double Dielectric Barrier Discharge (DDBD) Plasma reactor. The flow rates used were 0.1 L/minute, 0.4 L/minute and 0.7 L/minute for 1 hour, 3 hours and 5 hours. The results showed that the peroxide value increased with increasing oxygen flow rate and ozonation time. The highest peroxide value was obtained at a flow rate of 0.7 L/minute for 5 hours, namely 332.03 mg Eq/kg Sumbawa oil. Increased by 282.71 mg Eq/kg; the peroxide figure for Sumbawa oil without ozonation was 49.32 mg Eq/kg.
