Indonesia is a country encircled by the Pacific ring of fire, so it has a high potential for natural disasters, especially earthquakes. Responses to efforts to provide information and increase students' understanding of natural disasters and mitigation have been carried out through the world of education. The aim of the study was to identify and analyze the effect of understanding earthquake disaster mitigation and self-concept on disaster preparedness. This type of quantitative research with data collection methods in the form of questionnaires. The time of the research was carried out from September to December 2022. The research location was at SMAN 5 Depok. The results of the study show that there is a partial and simultaneous effect of understanding earthquake disaster mitigation and self-concept on disaster preparedness in class XI students of SMA N 5 Depok, West Java. This means that the more understanding of earthquake disaster mitigation and self-concept increases, the more disaster preparedness the students will have. A greater influence on student disaster preparedness is self-concept. The research recommendation is the need for continuous learning about earthquake disaster mitigation and self-concept towards disaster preparedness in students. This aims to increase student understanding regarding natural disaster mitigation.

Small Scale Gold Mining (ASGM) in Indonesia is carried out using amalgamation techniques which produce mercury waste and have the potential to pollute the surrounding environment. Mercury contamination is suspected to have occurred in the Ciherang River. This study aims to analyze mercury levels in river water and the benthos of the Ciherang River with a difference of 0.28 km before mining, 0.51 km after mining and 1.42 km after mining. Water and benthos samples were taken using a water sampler while benthos used an Ekman grab which was then taken to the laboratory and analyzed for mercury levels with a mercury analyzer. The mercury level in Ciherang River water ranges from 0.0002 mg/L – 0.0005 mg/L. While the mercury content in benthos ranges from 0.04 mg/kg – 0.2 mg/kg.

The amount of water usage is not comparable to the amount flowed to WWTP due to the remote location and indications of leaks in the wastewater piping system, so an ecoefficient analysis of wastewater recycling of IP washing machines at PT X is needed. The type of data in this study consists of primary and secondary data. The primary data needed are the amount of clean water usage per machine, the amount of wastewater generation, and the effluent quality of wastewater. The results showed that the efficiency process was carried out by analyzing clean water usage, measuring wastewater generation, calculating the cost of using clean water and wastewater treatment costs, as well as measuring effluent quality on color parameters and TDS. It is obtained that the effluent quality results still meet government regulatory standards, so that it can be used as raw water in applying wastewater recycling, and wastewater can be flowed directly through sand filter media and carbon filters contained in IP plants, without being treated first at wastewater treatment plants. The amount of savings in implementing ecoefficiency in reducing groundwater use is 87% or 2331.8 m3 / month from the use of IP washing process water and wastewater treatment cost savings of Rp 3,807,370 / month.

Sanitation in Kampung Bengek, which is located in the RW 17 Muara Baru area, Penjaringan, North Jakarta, will be a portrait that needs to be considered for alleviating sanitation problems. Sanitation problems in Bengek Village in general can be seen from the low quality and level of sanitation services, especially the large number of residents who do not have private toilets, even though there are toilet and washing facilities (MCK) but their utilization and management are still not optimal. This study aims to determine the relationship between community knowledge about environmental sanitation and clean living behavior with the quality of MCK sanitation in Bengek Village, Muara Baru, North Jakarta. The method used is a survey method with variable X1 Knowledge of environmental sanitation, X2 Clean living behavior and variable Y Quality of MCK sanitation. Data was collected using a questionnaire instrument (questionnaire). The results of the study found a significant positive relationship between the three variables X1, X2, and Y between community knowledge about environmental sanitation and clean living behavior with the quality of MCK sanitation. In other words, the higher the level of public knowledge about environmental sanitation and the better the behavior of clean living, the better the condition of the quality of MCK sanitation.

The purpose of this study is to determine the patterns of self-managed waste management in building a Green International Business District in the Kemayoran area. The method used in this research is a survey with descriptive qualitative analysis. Data analysis in this study was carried out interactively which included: data presentation and drawing conclusions. The data used uses data from the results of collecting types of waste collection patterns, the research location is in the Kemayoran area, Central Jakarta, this research was carried out from March to July 2020. The land area of this study covers 454 ha and most of it is heterogeneous waste, almost 50% is green waste or regional waste that dominates, the rest is office and household waste, but there is something unique in this area's waste movement, because some of it is an active area for international events so the waste is the products of leftovers. The event is R3 (Reduce, Reuse, Ryclycle). The results of the study indicate that the background for the realization of community-based environmental management is the Kemayoran area, which is located in the center of the city, which often experiences floods. In terms of human resources, about 75%% are employed from residents around Kemayoran, so they can control their management every day. People who are empowered in waste management are able to organize joint activities to solve waste problems, and form awareness in responding to waste problems on the basis of common interests. The results of field observations show that waste is managed with a fairly good selection although there are still some patterns that still use the burning method, although the percentage is small. To support the government, the Area Management has tried to support the implementation of good waste management as regulated in Law no. 18 of 2008 concerning Waste Management. These implementing regulations are urgently needed for Area Managers in innovating to develop economic activities in waste management. In an effort to make this happen, various obstacles were encountered, including acts of vandalism and the public's lack of awareness in disposing of waste in its place.
