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

Recipients of the COVID-19 vaccine in Central Lampung District dose 1 were 898,900 (81.95%) of the 80% target. Those who received the 2nd dose vaccine were 683,002 (62.27%) of the 70% target and booster vaccines by 23,665 (2.16%) of the 40% target. The study aimed to analyze the predisposing factors that influence participation in the COVID-19 vaccination in the community in Central Lampung district in 2022.Subjects and Method: A cross-sectional study was conducted in three sub-districts of Central Lampung district from July to September 2022. A total of 110 people were selected for this study. The dependent variable was the decision of participating in the COVID-19 vaccination. The inde­pendent variables were Knowledge, Education, Attitudes, Health Information, and Trust. Data was collected by using a questionnaire. Data were analyzed using a logistic regression test.Results: Health information (aOR= 18.58; 95% CI= 1.83 to 188.05; p= 0.013), and level of trust (aOR= 18.54; 95% CI= 2.77 to 123.80; p= 0.003) were related to community participation in the COVID-19 vaccination.Conclusion: Health information and public trust related to participation in the COVID-19 vaccination in the community. Keywords: predisposing factors, behavior, COVID-19 vaccination.Correspondence:Bambang Pujianto.

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.
