The problem that has been difficult to overcome until now is the waste problem. Landfilling remains a method that is often used but has a disadvantage in the form of leachate production. Leachate or leachate is defined as wastewater produced from Final Disposal Sites (TPA). The combination of electrocoagulation and adsorption methods can be a promising treatment technology. The electrocoagulation process was carried out for 1 hour using iron electrodes. The variations used are electrode distances consisting of 1 cm, 1.5 cm, and 2 cm while the voltages consist of 10 volts, 20 volts, and 30 volts. In adsorption, zeolite adsorbent was used with a residence time of 2 hours. The research stages started from the preparation of leachate samples, examination of initial characteristics, leachate treatment, and testing of COD, TSS, and pH. The results showed that the optimal variation was obtained at a distance of 1 cm and a voltage of 30 volts with a COD efficiency of 98.84% and TSS of 99.82%. For the pH value, the result is that the greater the distance between the electrodes and the voltage, the higher the pH value obtained.

“…The NO2 sample was read using a UV-Vis spectrophotometer with a wavelength of 550 nm and the absorbance results were obtained which can be seen in Table 1. Based on the Absorbance value obtained after calculating the NO2 content value in the instrument room and preparation room is below the method limit, namely <0.0066 μg/m 3 .…”

“…Nitrogen dioxide gas (NO2) is a gas pollutant that generally comes from smoke petrol vehicles, waste burning and coal industry [2,3]. Gas NO 2 has a characteristic sharp odor, reddish brown and colored yellow below 21.2 0 C. NO2 gas has low solubility in water and dissolves in alkaline solutions.…”

Universitas Pakuan is one of the universities in Bogor which has a chemistry education laboratory for practical purposes. In this study, the room tested is the instrument room and preparation room. Air testing of this work environment refers to the Minister of Manpower Regulation No. 05 of 2018. The test results for the instrument room and preparation room found that the levels of nitrogen dioxide (NO2) and ozone (O3) in the two rooms do not show any indication of NO2 and O3 pollution with result values below the detection limit testing (<0.0066 ppm and <0.0491 ppm).

“…The higher the COD value in wastewater, it indicates that the degree of pollution is also higher. This initial waste characterization is a sign that waste must be managed first before being discharged into the environment [3]. High TSS values in waters will reduce the use value of waters and affect the organisms that live in them and affect water clarity [4].…”

Liquid confectionery waste water treatment is carried out using a combination of batch system electrocoagulation methods and irradiation by UV light. The variations of contat time applied were 30, 45, 60, and 75 minutes, the electrode distance was 2 cm and voltage variation was 20 and 30 volts. In addition to reducing pollutant levels, UV lamps are also used to remove odors. The result showed that the electrocoagulation process and UV irradiation could reduce pollutant levels maximally at 30 volts 73 minutes. COD level decreased to 1646,40 mg/L (efficiency 76,34%) and TSS to 50 mg/L (efficiency 88,68%). UV irradiation is also effective in removing the odor of soft confectionery wastewater. This result meets the wastewater quality stabdard according to PerMenLH No. 5 of 2015 Appendix XXVI, it’s just that COD does not meet the quality standards, therefore further research is needed.
