Published: February 2022

Abstract
Nature-based Solution (NBS) is an umbrella for ecosystem-based approaches to prevent or mitigate the impacts of hydro-meteorological hazards. The increasing hydro-meteorological disaster occurrence such as floods in Bandung City because of both climate change phenomenon and rapid growth of Bandung City has caused a big impact on people live in slums and high-density settlement. Realizing this risk, Bandung City has implemented strategies to reduce flood risk, including the Sustainable Urban Drainage System (SUDS) as stated on the Bandung City Spatial Plan (RTRW) 2011-2031. However, this measure had not effectively reduced flood risk in Bandung City. Therefore, this research focuses to analyse the implementation of SUDS and how it can capture the concept of NBS, with the study case Cibadak Administrative Village, one of the poor and high-density urban settlements in Bandung City. The result was developed using a mixed method consisting of a descriptive quantitative approach, spatial analysis for satellite imagery, and content analysis technique to analyse each challenge of SUDS implementation. The result indicates the lack of capacity in scale, budget, natural characteristic, and social demographic for SUDS implementation in poor and high-density urban settlement in Bandung, which aligns with the challenge of NBS implementation in the global south.

Abstract
The COVID-19 pandemic has made many people aware of the real condition of the national health system. The efforts to handle the pandemic occurred simultaneously throughout the territory of Indonesia that had never been thought of before. The Ministry of Health through the Health offices is working hard to tackle the Covid 19 outbreak. Public Health Centers are the technical implementing units in each region that have duties in carrying out promotive, preventive, curative, and rehabilitative efforts. Problems arise when the service standards of the public health center are not the same in all regions of Indonesia. On the other hand, the reachability of health facilities is still a problem in some places. In this study, we are interested in mapping the pattern and reachability of level one health facilities in Nguter Sub-District, Sukoharjo Regency, Central Java, Indonesia using a geographic information system (GIS). This study would be spatially analysed by using nearest neighbour method in ArcGIS. The evaluation of reachability was done by using a minimum service standard by the Decree of the Minister of Settlement and Regional Infrastructure No. 534/KPTS/M/2001. The results showed that the mapped health facilities in Nguter Sub-District were 2 Public Health Centers and 3 Sub-Public Health Centers. Based on the analysis of the nearest neighbors, the public health center in the Nguter Sub-District show a dispersed pattern. From the results of buffering, it is known that almost the entire area of Nguter Sub-District has covered by the Public Health Centers and Sub-Public health centers.

Published: February 2022

Abstract
Development in accordance with disaster mitigation policies in urban areas sometimes involves relocation and forced eviction of people living in informal settlements. Semarang City has the same experience. In 2019 the normalization project of the Banjir Kanal Timur river as a government effort to control flooding had displaced the local communities in Tambakrejo. This paper aims to criticize the implementation of flood disaster mitigation projects that impact poor households and assess their livelihood assets after displacement. Utilizing spatial data and primary data collection using the purposive sampling method were carried out during the fieldwork. The findings highlight that, irrespective of potential opportunities to avoid local communities from flood risk and safer place to live, on the other hand, local communities experience impacts on their livelihood assets and unclear compensation for their assets. This phenomenon proves that there are still many challenges to creating safe, comfortable, and sustainable urban development mandated in Law No. 26 of 2007. In the name of national projects, this action has taken away the “right to the city”, has increased marginalized urban communities, and the emergence of urban social issues such as the affected communities’ dissatisfaction with local government authorities

Published: February 2022

Abstract
The research aims to determine the existing external event for Nuclear Power Plant (NPP) Siting project at West Kalimantan. The identification of external hazard potential studies is carried out based on the IAEA safety guide and BAPETEN regulations regarding external potential hazards which include seismic aspects, surface faults, extreme meteorology, geotechnics, volcanoes which must be carried out in determining the NPP’s site. The method used in this research is field ground check and desk work analysis with references related to identified external hazards. The results showed that the potential site of the NPP’s in West Kalimantan Province is safe from potential external natural hazards. The NPP’s site has also been determined to be safe from the dangers of flooding due to tsunamis and flood overflows, no capable faults are found, and far from potential volcanic hazards. Extreme meteorological potential is rare at site sites. To evaluate the oceanography aspect, the existence of physical oceanographic conditions must be carried out in-depth studies in the future, especially related to the sedimentation process that has occurred around the nuclear power plant site.

Abstract
Jakarta, the capital city of Indonesia, is the most populated area in Indonesia, with a population of 10.56 million people or around 3.91% of the total Indonesian population. Jakarta has also become an important city in Indonesia as around 80% of Indonesian economic activity is located in this area. No doubt, the urban activity caused the air pollution to infuriate its microclimate, including the urban heat island phenomena. During the Covid-19 pandemic, Indonesia applied the partial lockdown for several areas to decrease virus transmission. Most of the transportation and commercial areas were closed, and most people worked from home. This significant shifting will affect the temperature and urban heat island conditions. Thus, the main objective of this research was to analyse the urban heat island during the early stage of the pandemic in Jakarta. We used Landsat 8 imagery to extract the land surface temperature (LST) and generated the urban heat island (UHI). The correlation was used to determine the relationship between the distribution of covid-19 cases with the UHI distribution. From the four different recording times (May, July, September, and December 2020) of Landsat 8 imagery, the highest UHI, 7.76°C was found in December 2020 (the late first year of the pandemic). The lowest UHI, 4.91°C was found in May 2020 (The early stage of the first year). Furthermore, the UHI hot spot moved from almost evenly in East Jakarta in May 2020, a tiny spot in East Jakarta in July and September 2020, and evenly distributed in Southeast Jakarta in December 2020. In addition, we found that the increase of covid-19 cases had a positive correlation with the UHI in Jakarta, which means the areas with the high UHI value have high new covid-19 cases. These results showed that the area with high activities is very prone to covid-19 transmission.

Abstract
Cities in developing countries are heavily involved in urban agricultural activities, and a lot of research has been done to address the challenges in this regard. However, several studies have proposed taking advantage of them in reducing the impact of urban heat islands (UHIs), which are manifested as a consequence of stringent changes in energy use, human settlement patterns, industry, transportation, and population growth. Data for this study were obtained from a literature search of existing academic journals, the domain of agriculturally related organisations, and books; the investigation was mainly based on developing nations. Best practices of scholarly work did the review. Authors stand posited. Urban farming has been employed in cities mainly as a food source while also catering to the changing needs of the urban dweller’s lifestyles. There is an urgent need to investigate the potentials of urban farming not just as food crops but as green infrastructure in ameliorating urban heat island intensities in our cities.

Published: February 2022

Abstract
Cengklik Reservoir is one of the water sources that has the main function for irrigation and aquaculture. Based on satellite imagery of the Cengklik Reservoir 2000-2020, about 30% of the waters of the Cengklik Reservoir have been covered by water hyacinth. The use of chemical fertilizers, pesticides and fish farming activities using floating net cages are the main factors causing eutrophication. Therefore, the purpose of this study was to analyze the water quality of the Cengklik Reservoir at the inlet and outlet points of the Cengklik Reservoir and then determine the level of pollution using the Pollution Index (PI) method. The water quality parameters tested were temperature, pH, TSS, DO, BOD, COD, TSS, Total-P, and Total N. Based on the results of the PI analysis, the water quality of Cengklik Reservoir was categorized as lightly polluted and does not exceed the quality standard value of Government Regulation No. 22 years 2021 other than phosphate. Phosphate parameter values at inflow 1, inflow 2, inflow 3 and outflow locations are 0.166 mg/L; 0.166 mg/L; 0.723 mg/L and 0.166 mg/L which are estimates of the cause of eutrophication in the Cengklik Reservoir.
Study on the Application of Phytoremediation of Phosphate Content to Eutrophication in Cengklik Reservoir, Boyolali Regency

Published: February 2022

Abstract
Cengklik Reservoir is a reservoir for water from agricultural irrigation flows that use chemical fertilizers so that there is an increase in nutrients in the waters. Eutrophication is an environmental problem caused by an increase in nutrients such as nitrogen and phosphorus in aquatic ecosystems. Phytoremediation is a technique that is more efficient and economical than conventional techniques in degrading excess nutrients in polluted air. In phytoremediation, plants absorb air pollutants such as NO3-, NH4+ and PO43- directly. The purpose of this study was to examine the potential of aquatic plants in wastewater phytoremediation and provide recommendations for phytoremediation potential for the waters of the Cengklik Reservoir. The method used in this research is Systematic Literature Review (SLR). Based on the research that has been done, the Pistia stratiotes plant has been widely used as agricultural and domestic wastewater treatment. Pistia stratiotes has the potential to remove 80-95% of the phosphate content. So that the Pistia stratiotes plant is a suitable plant to be applied in the waters of the Cengklik Reservoir. The phytoremediation application was carried out in an inflow reservoir with a plant cover area of 75% of the phytoremediation area, and harvesting was carried out on the 14th day of treatment. The harvest can be utilized or managed by the community or related agencies to become a bioenergy generator.

Abstract
The Garang River is the city of Semarang’s primary source of water, particularly for drinking water and other domestic needs. This research attempts to examine the current water quality status of the Garang River Basin by using the Malaysian Water Quality Index (WQI). Six water quality parameters were selected and analysed; DO, BOD, pH COD, NH3-N and TSS. Water sampling was conducted at eight stations based on the Governor Regulation of Central Java No. 156 (2010) on Water Allocation and Water Quality Management of Garang River. Water quality was sampled twice, once during the rainy season (2 January 2020) and once during the drought season (1 September 2020). The findings of the study showed that the water quality status of the Garang River Basin during the rainy season recorded a WQI value of 81 and 92 during the drought season. Both values belong to Class II, which represents clean waters. Three water quality parameters were identified to have exceeded the set standards: the DO, BOD, and NH3-N. Changes in landuse, particularly the clearance of forest areas for agriculture, plantation activities, domestic waste disposal, and wastewater directly from industrial activity and local inhabitants, have all contributed to the Garang River Basin’s deterioration of water quality. However, in the context of water classes, it is shown that the water of the Garang River is suitable to be used as a domestic water supply for local residents but requires further treatment prior to consumption.

Abstract
An effectiveness of the protected or rehabilitated natural assets will provide information on the availability of natural resources to respond to the impacts of climate change and ecosystem health. The emergence of the COVID-19 pandemic disaster increasingly shows that if humans destroy biodiversity, it also destroys human life-support systems. The purpose of the research to obtain a dynamic-empirical description of the availability of clean water for drinking water for residents in areas exposed to the Covid-19 pandemic as an implementation of an environmental monitoring system for ecosystem services. The research method uses quantitative methods. The results showed that: (1) although the low pressure area affected the number of customer complaints, it was not entirely the main factor that most dominantly affected the number of complaints of small water, dead water, and water quality in the studied area. (2) The results of the R square regression test show the percentage of the influence of low pressure areas on complaints of small water complaints, dead water, and water quality; is below 100%. The conclusion shows that although low water pressure occurs in areas exposed to Covid-19 in DKI Jakarta, it does not always affect customer complaints. This is because low water pressure is not entirely caused by small water, dead water, or water quality. Therefore, the environmental monitoring system for the availability of drinking water for the population as an ecosystem service pays more attention to other parameters besides small water, dead water, and water quality.

Published: February 2022

Abstract
The study of watershed hydrological response is essentially to understand the hydrological characteristics produced by specific rainfall on the watershed area. These flow parameters also rely on watershed factors such as land use, soil type, and watershed morphometry. The research was performed in the Cileungsi watershed, Bogor Regency, West Java. This research aimed to determine the hydrological response and to investigate the water yield of the Cileungsi watershed. Distributed hydrological modelling was used. Curve Numbers (CN) were estimated using SCS-UH triangular hydrograph technique, while the baseflow was determined using the exponential recession method. Muskingum-Cunge flow routing techniques were used to calculate the flow hydrograph. Yearly water yield was estimated based on measured rainfall data. The simulated hydrograph of several flood event shows similarities to the measured hydrograph. It is based on calibration and optimization of the model parameters. The objective function values are less than 15 percent, with peak discharge range from 654-1,729 m3/second. The hydrograph form tends to feature a rising limb that climbs rapidly with a sloping recession limb. The result of this research shows that the Cilengsi water yield are 4,520.33 mm.

Published: February 2022

Abstract
Oil and gas producing enterprises at all stages of the life cycle have a negative impact on the components of the natural environment: atmosphere, soil, surface water bodies and groundwater. One of the serious environmental problems is the formation of drilling sludge during the construction of wells for oil and gas production. Some enterprises have debts on illiquid sludge barns. One of the reasons for this state of affairs is the shortcomings in the calculation of the actual volumes of sludge formed during drilling. The analysis of the existing methods for calculating drilling waste, literature sources and available materials for calculating the volume of drilling mud has revealed certain inaccuracies (errors) in calculating the volume of drilling mud and some unaccounted factors associated with the operation of drilling tools. A computational experiment was carried out and, using the example of one of the oil and gas producing enterprises, a comparison of the volumes of drilling sludge was made, taking into account possible errors, and a discrepancy of 181 m3 of drilling sludge per well was revealed. The elimination of errors in the calculation of waste generation standards and limits on their placement during the construction of wells will allow to adjust the volume of drilling waste generated and prevent the occurrence of possible environmental problems at the sites of well construction.
