Abstract

Land subsidence has long occurred around the Special Capital Region of Jakarta. It is important to know and deal with Land subsidence events which also cause various negative impacts. Aim: When large amounts of groundwater are withdrawn from certain types of rocks, such as fine-grained sediments, land subsidence occurs. The rock compacts because the water helps to keep the ground in place. When the water is removed, the rocks collapse in on themselves.The immediate impact is the building collapse around the Kota Tua of DKI Jakarta. Methodology and Results: The research method used is a quantitative descriptive survey method by observing the amount of land subsidence that occurs in the Kota Tua area and its surroundings. The results showed that there has been a vertical land subsidence that varies between 20-60 cm. Based on the results of the resistivity values and coordinates plotted on the Regional Geological Map (Jakarta and Kep Seribu), the research location is classified into Lithology: Clay, Sand Silt, Gravel, and Pebbles (Quartenary deposits). The phenomenon, land subsidence, is caused by a combination of various parameters, including natural consolidation of alluvial soils, excessive groundwater extraction, and also building loads from infrastructure development and tectonic factors. Conclusion, significance, and impact study: Knowing the value of land subsidence and its location is expected to support urban planning, basic infrastructure planning and development, housing, settlement planning, and local financial improvement in efforts to mitigate land subsidence disasters.

Abstract

Aim: The study aimed to investigate the impact of rainwater on the acidity levelsto monitor acid deposition and identify sources of pollutant that affect the acidity concentrations of rainwater. Methodology and Results: One unit of rainwater sampler in each location was employed, andsamples were taken to the National Research and Innovation Agency laboratory (BRIN) for analysis of rainwater quality including acidity/pH degree, conductivity, and ion concentrations. The results show that high rainfall intensity (>300 mm/month) in April and December 2019 led to a decrease in electrical conductivity (<10 mS/cm) and ion compounds (>200 μmol/L) of rainwater, likely due to the dissolution/washing process of anions in the air during the rainy season and acid and alkaline neutralization in the dry season. The most identified chemical compounds were ammonium (NH4+), sulfate (SO42-), nitrate (NO3-), and salt (NaCl). Conclusion, significance, and impact study: Based on back-trajectory projections, the decline in rainwater quality was attributed to both local emissions (transportation, industry, agriculture, and waste burning) and long-range sources (earth crust, oceans, coastlines, marine activities, and anthropogenic and forest fires in the Australian territory).

Abstract

The issue of environment and sustainable energy are two issues that have not been completely resolved until today. Liquid waste treatment technology, which can remove pollutants and produce hydrogen gas, is interesting to study since hydrogen itself is one of the energy sources whose use has begun to be developed. Aim: The following article will discuss several aspects that can be developed in each technology. Methodology and Results: Electrocoagulation and photocatalyst are both technologies which are possible to eliminate liquid pollutants while producing hydrogen in a single process. Research that attempts to combine two processes to improve the ability to treat pollutants in wastewater while producing hydrogen has been carried out. The optimization process can be carried out respectively in terms of electrocoagulation and photocatalytic technology. Modifications can also be made by combining the two processes of electrocoagulation and photocatalysis, either sequentially or simultaneously. Modification process carried out aims to increase hydrogen recovery without neglecting the ability of electrocoagulation and photocatalysis in removing organic waste. Conclusion, significance, and impact of study: This brief review provides an overview of the potential of electrocoagulation and photocatalysis technology in its ability to remove liquid waste while producing hydrogen gas. The opportunity to combine the two processes is also shown based on previous studies. The review is carried out based on an in-depth study of the research that has been done. The simultaneous use of both processes has been shown to provide much better capabilities in terms of removing liquid waste and producing hydrogen gas.

Abstract

Globalization causes multinational entrepreneurs to move their business locations across geographical boundaries. The Multinational Entrepreneurs running businesses across geographic boundaries are called Foreign Direct Investment (FDI). One factor that determines the success of FDI is the accurate choice of investment location. Currently, Climate Change plays a significant role in business decisions. Aim: This study aimed to assess the selection of investment locations using the demand-side analysis and environmental policies approach. Methodology and results: The sample was the Electronic and Automotive industry located in the JABABEKA Industrial Estate, Jakarta, Indonesia. The primary data were collected from the respondents' perceptions and processed using the Structural Equation Model (SEM) method. The SEM-PLS results showed that the path coefficient of the relationship between Environmental Regulations and the Investment Locations Choice was 0.314. Therefore, Environmental Regulation significantly affected Investment Locations Choice. Furthermore, the path coefficient of the relationship between Environmental Litigation and the Investment Locations Choice was 0.113, with a P-value > 0.05. This means that Environmental Litigation insignificantly affects the Investment Locations Choice. Conclusion, significance, and impact: Environmental regulations and litigation affect the location selection by investors. Therefore, urban planners should formulate policies for providing better waste and air pollution treatment facilities in each industrial area to increase the attractiveness of Indonesia as a Host Country.

Abstract

Unmanaged waste can cause various problems of environmental damage including threatening tourism development. The current waste problem is quite worrying because it can have a direct impact on humans, such as the entry of plastic elements into the human body through fish or food exposed to microplastics. Aim: The waste bank around Lake Tondano tourism object was studied qualitatively with the aim of describing the waste bank management mechanism to be used as a model for developing a waste bank to support sustainable tourism development. Methodogy and Results: The research data was obtained through field research through observations and interviews with waste banks around the Tondano lake tourist attraction, in this case the Mapalus waste bank located in Papakelan Village. Conclusion, significance, and impact study: The results show that the current form of waste bank management on the shores of Lake Tondano is a waste bank that is purely managed by the community. The form of management is to collect waste from the community by first going through a sorting process. After sorting, organic waste is used as fertilizer and inorganic waste is made into valuable products and can be used as souvenirs for tourists. The waste bank program can reduce the increase in waste directly from the source. In addition, the waste bank can produce new products and provide benefits to the community. The waste bank is also a solution in the context of developing tourism on the coast of Lake Tondano.

Abstract

The Coal-Fired Power Plants with low-emissions plants in the power sector can avoid nearly 800 million tonnes CO2 by 2030. The number of populations, Gross Domestic Product (GDP), electricity generation, NDC, and relevant energy policies influenced the prediction of Carbon Dioxide (CO2) emission from electricity generation. Aim: The objective is to analyze trends of CO2 growth related to electricity generation activities from countries in ASEAN with an emphasis on identifying the factors that influence it and evaluating the effectiveness of existing decarbonization policies in AMS and developing suitable strategies to reduce future CO2 emissions. Methodology and Result: Predicting CO2 emissions is conducted using three approaches by considering the newest NDC and energy policies, conducted by descriptive and quantitative analysis based on secondary data of (1) general information on ASEAN Member States (AMS), (2) information on power plants, (3) information on fuel use in electricity generation, and (4) decarbonization policies in AMS. Results indicated that the availability of potential energy sources (coal/oil/gas/RE) influences the dominant energy used in AMS Prediction of CO2e emission in the 2020 to 2040 period identified Vietnam as one of the highest CO2e emitters (380,1 Mt CO2e) in the electricity sector by 2030. Conclusion, significance and impact study: AMS needs to make a more aggressive energy policy to reduce CO2 level significantly, achieving the 2050 net zero transition targets. Ultimately, the shifting from coal-fired electricity plants to other fuel sources with a lower emission factor proves to be the most significant factor towards emission reduction.

Abstract

Aim: This study aims to treat leachate by using the constructed wetland. Moreover, the study of the usage of solid waste as a part of constructed wetland was also carried out to analyze the potential of solid waste utilization as filter media. Methodology and Results: Two different alternatives were proposed to obtain the best system, i.e., conventionally constructed wetlands with gravel, sand, and rock as the filtration media, and constructed wetlands that utilize solid waste as the media. The leachate was treated in a constructed wetland using the pandan plant through a phytoremediation process. The results showed that constructed wetlands were able to reduce BOD, COD, nitrate, and phosphate concentrations up to 87.3%, 87.7%, 86%, and 99.7% in a conventionally constructed wetland, also up to 77.1%, 76.9%, 98%, and 98.9% in constructed wetland using solid waste. The analysis results show that the TSS value still exceeds the quality standard due to suspended particles in the water. Conclusion, significance, and impact study: The results showed that constructed wetland significantly affected the reduction of BOD, COD, nitrate, and phosphate but did not significantly reduce TSS. Therefore, additional technology, such as a sedimentation tank, is needed. This ecologically constructed wetland is the first step in achieving sustainable development.

Abstract

The increase in mask waste and a lack of understanding about the management of single-use mask waste raises the potential for environmental pollution and COVID-19 transmission. Aim: This study aimed to assess the level of understanding of medical mask waste management and strengthening health protocols in controlling COVID-19 infection in Banjar Purwa Santhi, Benoa, Badung Regency. Methodology and Results: A cross-sectional method and descriptive study design were used with a sample of 100 respondents selected via stratified sampling. The research and service activities at Banjar Purwa Santhi Benoa include public campaign and assessment of the level understanding of medical mask waste management. Based on univariate analysis, 91% of respondents know that mask waste contains hazardous and toxic substances. If mask waste is disposed carelessly, 98% of respondents stated that it can pollute the environment, and 98% of respondents also stated that it has the potential to become a means of transmitting COVID-19. However, 85% of respondents disposed of the masks in the household trash. Conclusion, significance and impact study: Respondents had a good level of knowledge about health protocols and mask waste management but have not separated masks from household waste. By holding the community service activity, it is hoped that changes in community behavior will occur.

Abstract

The growth of the Tangerang area reflects the urban growth trend which leads to a wider growth pattern to the area around the Major City. One indication of the growth is the character changed of settlements that previously had a rural character into urban character, especially in building density. The growth in the number of houses as residences has resulted in changes in the type of open space and its use.  Aim: This research aims to identify the type and character of open spaces in unplanned settlements that are growth very quickly because of the area directly adjacent to the Gading Serpong new town. Methodology and Results: The method used is descriptive qualitative. The type of open space is measured by the criteria of location, form, function, and land status. The character of open space is studied by connecting the existence of open space with the social interaction of the residents of the settlement. Conclusion, significance, and impact of study: The findings that have been obtained from this research are that open spaces have five types with a very prominent spatial character, namely open spaces that arise through natural social processes, are not specially designed and have a very important role in bonding the social interaction of their inhabitants.
