Abstract

Mojowangi Village, Mojowarno District, Jombang Regency, is a village that has strong cultural potential. However, this village also faces environmental weaknesses in the form of increasingly worrying plastic waste problems. Ecobrick socialization in Mojowangi Village is a very important effort to overcome the problem of plastic waste. Using a participatory method, this activity involves PKK mothers in making ecobricks, namely plastic bottles filled with solid plastic waste. The main objective is to increase community awareness and skills in sustainable plastic waste management. This activity also contributes to achieving the Sustainable Development Goals (SDGs), especially goals number 11 (Sustainable Cities and Settlements) and number 12 (Responsible Consumption and Production). The results of the activity show an increase in community awareness, skills, and active participation, as well as opening up new economic opportunities for the community. Thus, this activity not only has a positive impact on the environment but can also improve the economy of the local community

Abstract

The utilization of gadung tubers as an alternative food has limitations due to the presence of cyanide content, which can cause poisoning. The cyanide content is cyanogenic glycosides, which can be enzymatically hydrolyzed to form cyanide acid compounds (HCN). The cyanide content in gadung tubers averages around 362 ppm, while the safe limit for consumption of cyanide acid levels is ≤ 10 ppm. This study aims to reduce the cyanide acid content in gadung tubers through a maceration extraction process with a combination of Sodium Bicarbonate (NaHCO₃) and Sodium Chloride (NaCl) solvents so that it complies with the World Health Organization (WHO) standards. Gadung tuber extract was obtained from maceration extraction for 30 minutes in each solvent. Testing methods for cyanide acid in Gadung tubers include Titrimetry, Spectrophotometry, and Organoleptic. The combination of high concentrations of Sodium Bicarbonate (NaHCO₃) and Sodium Chloride (NaCl) can help reduce cyanide acid levels in gadung tubers. The initial cyanide acid level of 47.02 mg/kg can be reduced with the best concentration combination (10:15)%, where the analysis results in titrimetry amounted to 9 mg/kg, while in spectrophotometry it was 9.5 mg/kg. This shows that cyanide acid levels can be reduced by 80-81% so that these levels meet World Health Organization (WHO) standards.
