This study aims to investigate the effectiveness chicken eggshells as a biocoagulant for treating this groundwater. The techniques employed encompassed coagulation and flocculation, involving different coagulation G.td values (17,000, 34,000, 48,000, and 96,000) and a range of biocoagulant doses (100-500 mg/L). The outcomes of the treatment revealed that the utilization of chicken eggshells as a biocoagulant led to the removal of 47.14% of TDS and 97.17% of turbidity. The cost associated with implementing chicken eggshells as a biocoagulant amounted to IDR 230.70 per liter. In light of these findings, it can be deduced that chicken eggshells serve as an effective biocoagulant for reducing TDS and turbidity in the groundwater treatment.","PeriodicalId":472381,"journal":{"name":"Journal of community based environmental engineering and management","volume":"55 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140424048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Urbanization and community agglomeration in urban areas in Indonesia are increasing the complexity of solid waste management in Indonesia. The old paradigm of 'collect-transport-disposal' waste management still occurs frequently in cities in Indonesia. This research is designed to be a systematic qualitative review. The relationships between good environmental governance and sustainable solid waste management are synthesized from a perspective of current conditions in Indonesia. The solution to sustainable waste management is generally carried out through well-organized waste management in an integrated manner from upstream to downstream with a 'cradle-to-grave' mindset, including the impacts that may arise therein. Implementing sustainable solid waste management requires commitment and support from all aspects of stakeholders. Good environmental governance is a comprehensive, dynamic, and complex concept that attempts to improve environmental conditions while promoting sustainable solid waste management. The results show that good environmental governance is very influential for sustainable solid waste management, but it still needs to be implemented optimally in Indonesia. Integration and synchronization of policies between the central government and local government must be further improved to implement good environmental governance.","PeriodicalId":472381,"journal":{"name":"Journal of community based environmental engineering and management","volume":"5 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140452763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the waste in the textile industry, is generated from the dyeing process and textile processing. PT X is a textile finishing industry, that focuses on finishing processes like dyeing and textile processing. In this research, GHG (greenhouse gasses) emission inventory was carried out to see how much GHG generated in the textile finishing industry. The inventory will focus on CO2, CH4, and N2O from generator, curing machine, operational vehicle, and electricity usage. The inventory methodology was based on IPCC 2006, that stated to determine GHG emission, an activity data and emission factor from that source is needed. This emission inventory results on the total emissions of 666.38 tonCO2eq or 258.629 kgCO2eq/tonproduct GHG emission from PT X in 2021. The GHG emission in PT X are dominated by CO2 gas. Which most of comes from electricity usage source.

Previous data and research show that the north coast of Java Island is a sensitive area to abrasion that was exacerbated by sea level rise and land subsidence, one of which occurs in Bedono Village, Demak Regency. Bedono Village is the village that has lost the most land. Based on the latest administrative boundary data, Bedono Village has been divided into three pockets surrounded by sea areas. This study aims to determine the spatial-temporal impacts of shoreline changes on land use in Bedono Village using Google Earth data. In the last two decades, there has been a significant change in the coastline and its impact on land use change. Residential areas continue to decrease in size, reaching 16.38 ha. Ponds, as the most dominating area in 2003, also continued to decrease in area by 127.27 ha or 100% of the initial area. The loss of this land use was replaced by the inundation of sea water that continued encroaching into the land area. A total of 197 residential building units were lost, or an average of 788 people were affected. This study concluded the severe facts and impacts of shoreline change that must be addressed to reduce potential losses.","PeriodicalId":472381,"journal":{"name":"Journal of community based environmental engineering and management","volume":"151 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140452400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Behavioural intentions of households can lead to reduce, reuse and recycle behaviour in waste management. Many factors influence the reduction of waste. Psychological and behavioural characteristics often hinder the effectiveness of technical solutions in managing household waste, so it is important to understand human behaviour to design effective policies. Rural areas also face waste problems, but they do not receive as much attention as urban areas. This research aims to identify the behavioural intentions of households to reduce waste in a small village in Bandung Barat Regency. This study uses Rasch model to measure a person's perspective in an objective way. Data for this study was collected using a questionnaire. The questions were rated on a five-point Likert scale. The number of respondents who participated in this study was 27. The small number of respondents was due to difficulties in finding respondents, as most people were farming at the time of the study. The result shows that the person’s reliability is statistically misfit, whereas the item reliability is fit. The respondent/person misfit may be because the respondents are farmers with a low level of education. The Cronbach's alpha value, which measures the interdependence between the person and the item, is 0.70. Since the item reliability is 0.95 and the person reliability is 0.62, it can be concluded that the quality of the items of the instrument is good, and the consistency of the respondents' answers is also good. Questionnaire item I8 is the most difficult question for respondents to agree with a value of +2.09 logit. On the other hand, the easiest questionnaire item to agree on is I18 with -1.74 logit. From the results it can be concluded that the respondents know about waste separation. However, they never carried out waste separation. It can be inferred that the behaviour of the respondents does not reflect their knowledge.","PeriodicalId":472381,"journal":{"name":"Journal of community based environmental engineering and management","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135248145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cities in Indonesia are also facing this problem. The rapid growth of urban areas puts a strain on existing water and sanitation infrastructure, making it difficult to meet the increasing demand for services. This can lead to inadequate mapping and planning for future needs. Water and sanitation mapping is an important tool for monitoring access to clean water and sanitation facilities to gather accurate data and improving access to clean water and sanitation. The purpose of this study is mapping water and sanitation condition and calculate the sanitation index. The mapping carried out includes source of drinking water, wastewater, drainage system, and solid waste disposal. The study was conducted in RW 06 Pasirluyu, a community neighbourhood in Bandung City. The methods used are questionnaire interviews and direct observation. The total respondents of study locations were 225 houses, but only 101 houses were willing to participate in the study. The study results show that 89% of respondents clean water source comes from deepwell groundwater for cooking and washing, wheran openmain source for drinking water is from bottled water, 89% of respondents use septic tank for their wastewater, 11% of respondents dispose their wastewater into open channels or conduct open defecation, 89% of the draineage is open drainage system, and 61% of the respondents conducted solid waste separation. Sanitation index assessment in RW 06 Pasirluyu calculated scored 1.25 for drinking water aspect, 1.23 domestic wastewater aspect. 1.21 drainage aspect, 1.02 domestic waste aspect.

However, this process leads to the emission of air pollutants, including sulfur dioxide (SO2), which is considered harmful. To mitigate this issue, Seawater Flue Gas Desulfurization (SWFGD) has been implemented as a control device to reduce the concentration of SO2. Previous studies on SWFGD have mainly focused on operational factors such as gas flow rate and liquid flow rate using artificial seawater as the absorbent. However, there is a lack of research on utilizing natural seawater, particularly from Indonesia, as the absorbent. Hence, this study aims to determine the efficiency of SO2 removal using Indonesia's natural seawater and investigate the influence of varying the L/G (liquid-to-gas) ratio on the overall removal efficiency. The study employed a packed tower reactor with a counter-current flow configuration. The gas concentration of SO2 used in this study is 1500 ppm, which is adjusted to match the existing conditions in the Steam Turbine Power Plant. The variations in seawater flow rate range from 150 to 250 liters/hour, while the variations in gas flow rate range from 1 to 10 m3/hour at 30oC. So, the L/G ratio value is within the range of 20.9 to 104.5. The results indicated that an increase in the L/G ratio corresponded to an increase in the total removal efficiency.
