Abstract

On the conventional landfill, the waste degradation requires a lot of time to make it through and it produces amethane gasfrom a anaerobic which could be dangerous if there is not an optimal processing. On this research,the writer uses 7 experimental reactors, 6 reactors given aeration treatments and leachate recirculation. Thevariations which have done in the research is leachate recirculation debit, namely (10 and 15) ml/minutes andcontinual lacheate’s flowing system and aeration variation, namely (3, 2, and 1)ml/minutes everyday. Theparameter which is measured is the reduction of waste volume, temperature, PH, BOD and COD for weeklyanalysis. The results of the analysis are that the aeration of 1 ml/minutes with leachate resirculation of 15ml/minutes is the best of aeration condition and it can increase the settlement process and reduction of BOD andCOD concentration in a short time of leachate. This reactor can increase the volume reduction as much as 14,14% in six week and it is bigger than control reactor. The concentration reduction of BOD is from 718, 24 mg/lbecomes 88,44 mg/l and the reduction of COD is from 1285,58 mg/l becomes 893,44 mg/l

Abstract

The purpose of this study was to determine, analyze the socialization of the continuous voter data updating program of the General Election Commission of Sidoarjo Regency. Qualitative descriptive research methods and data collection techniques through interviews, observation and documentation. Determination of informants is done by purposive sampling method. Data analysis techniques through data collection, data reduction, data presentation, drawing conclusions. The results of this study indicate that the socialization of the continuous voter data updating program of the General Election Commission of Sidoarjo Regency is by direct and indirect socialization. Direct socialization was carried out with the OPD regarding the ongoing voter data updating program of the General Election Commission of Sidoarjo Regency and carried out socialization in high schools (SMA) in Sidoarjo Regency. Meanwhile, indirect socialization is carried out using social media owned by the General Election Commission of Sidoarjo Regency.
