Published: February 2022

Abstract
One of the areas in Central Java Province that is prone to flooding is Sragen Regency. The distribution of flood disasters occurs in commensurate rivers and river confluences in lowlands which are dominated by settlements and agricultural land. The purpose of this study was to analyze the distribution of landforms along riverbanks in residential areas and rice fields, refugee shelter locations and evacuation routes for handling disaster risk reduction. The research method is grounded research by recording the population census and public facilities at the affected residential locations. Determination of evacuation locations and routes by using evacuation criteria parameters and safe distance parameters to determine the classification of refugee evacuation locations. The results of the study found that there was a lack of understanding of the landforms of river borders for agricultural and residential land, the utilization and loss of embankments on comparable rivers, especially in areas of interconnection between rivers in the lowlands. To minimize the risk of flooding, it is necessary to add EWS, river border land that is already owned by the community, the use of right of use must be gradually returned as a river border and the selection of the right location and route evacuation.

Abstract
Coastal areas are unique ecosystems because of the potential for abundant natural resources and hazards that can cause losses. Therefore, this study aims to identify the typology and coastal dynamics of Kukup, Ngrawe, Sepanjang, Drini, and Krakal, Indonesia, for analyzing the potential of natural resources and hazards. A rapid-integrated assessment was carried out to identify typology, genesis, and dynamics of coastal areas by conducting field surveys at locations that have been determined by purposive sampling. The results showed that wave erosion coast was formed in Ngrawe, Kukup, Drini, and Krakal. The marine deposition coast was formed in Ngrawe, Kukup, Sepanjang, Drini, and Krakal. Moreover, the coast built by organism can be found in Sepanjang, Drini, and Krakal. In contrast, the structurally shaped coast was formed in the western part of the Krakal. The coastal dynamics begin with geodynamic processes that form structurally shaped coast, hydrodynamics that form marine deposition coast, wave erosion coast, and ecodynamics that form coast built by organism typology. The potential of natural resources consists of fishery potential, agriculture, and natural beauty for tourism objects. In contrast, the potential hazards consist of earthquakes, tsunamis, tidal waves, rockfall, rip currents, topographic changes, and land-use changes. The coastal area management planning recommendations were Spatial Planning Regulation, Early Warning System, Evacuation Route and assembly point (shelter), Digital-based Information Dissemination, and building retrofitting.

Abstract
Energy is a basic material that can be used for economic development. Increasing growth requires continuous energy exploration, so it requires new energy sources and technological innovations in energy. Energy consumption makes a big contribution in influencing climate change in the presence of carbon. In Indonesia, with a fairly dense population, it certainly increases the most energy consumption. Based on this, the purpose of this study is to analyze the relationship between variables of energy consumption, carbon footprint as an indicator of climate change and economic growth. The energy consumption used in this study is the consumption of electrical energy, oil, gas and energy innovation as alternative energy that can be realized. The method used is VARX analysis. The use of this method is to analyze the relationship between variables and analyze the resulting impact on each variable. The results show that there is a correlation between energy consumption and economic growth. In addition, there is a significant impact of shocks on the energy consumption variable. The higher the level of energy consumption, the higher the carbon footprint. energy consumption cannot prevent climate change, while energy consumption provides benefits in minimizing carbon. so that energy consumption in Indonesia needs to be controlled.

Abstract
Semayang Village is one of the villages located on the lake of Semayang which is inundated every flood season. Semayang lake is a flood exposure lake, where the increase in standing water can reach >10 meters during a flood with a flood duration of >2 months. The purpose of this study was to determine the adaptation strategy of the semayang villagers in dealing with floods. Data collection techniques used the Rapid Rural Appraisal (RRA) method and interviews. Interviews were collected from 30 respondents in Semayang Village that were affected by the flood. The results showed that the overall adaptation carried out by the community in Semayang Village using houses on stilts with almost the same model, and some residents make terraced houses. In addition, each house has a backup board to raise the floor of the house when the flood crosses the floor of the house. there is also a floating house system attached to a tree or building around the floating house. In order to protect the house buildings from waves, a wave barrier was also built at the village entrance gate from the lake. This strategy makes the villagers of Semayang never evacuate and move from Lake Semayang even though they are always affected by flooding every year.

Published: February 2022

Abstract
Climate change has affected human life, especially farmers in rural areas. Their livelihoods are very dependent on the climate so that their socio-economic life becomes vulnerable. If there is a risk of crop failure, the community becomes vulnerable to poverty and hunger. This study determines the livelihood vulnerability of smallholders in Wonogiri District, Indonesia. Purposive sampling was used to select respondents in the sub-districts of Girimarto, Eromoko, and Tirtomoyo. The number of respondents was 120 households which were selected for farmers who only own less than 2 hectares of land. Descriptive statistics and modified social vulnerability index (SoVI) were used in data analysis. We measured the level of vulnerability for economic and social. The results show that climate change to social vulnerability index with SoVI scores of 0.68 for Tirtomoyo, 0.61 for Girimarto, and 0.55 for Eromoko, respectively. The differences in components between the three sample areas include regional gross domestic product (GDRP), poverty rate, population density, population growth rate, sex ratio, children, and elderly. The results of the study conclude that climate change has the potential to cause poverty levels in the three sub-districts to increase. In terms of resilience, they are quite resilient because they do not depend on government assistance. However, when climate change causes continuous crop failure, the level of resilience of farmers will also decline.

Abstract
The rapid growth of the Special Region of Yogyakarta makes the water shortage one of the problems that must be solved immediately. The study area is located between Semaki Gede and Muja Muju Village in the Umbulharjo district of Yogyakarta. Declining groundwater levels and droughts has caused an abnormal environmental behavior, as there are still many flood points when the rainy season arrives. Precipitation (mm) between 1976 and 2018 shows that the potential rainfall intensity of the Yogyakarta has not changed significantly. Therefore, it is possible to take advantage of the rainwater potential of an average of 7.23 mm per month, a maximum precipitation of 210.281 mm in November 2017 and a minimum precipitation of level 0 from May to October 2018. The method used is to load or recharge rainwater in the dug well to keep the groundwater level stable. In this study, GAMA Rainfilter rainwater injection technology was used and 10 excavated wells were used, of which 5 uninjected observation and research wells were excavated and 5 excavated injected observation and research wells. Observation of the groundwater level of 10 wells from 2018 to 2019 resulted in an additional production of 0.095 m or 9.5 cm. Changes in groundwater quality were successful and there are several indicators that need to be considered again in the testing methods process.

Published: February 2022

Abstract
Vulnerability mapping in urban planning is very important to reduce damage caused and loss of life due to disasters. This paper discussed the mapping of urban physical vulnerability using remote sensing, and geographic information systems (GIS) approaches. Physical vulnerability parameters used were building density, distribution of public facilities, slope, and land use. Landsat 8 OLI satellite imagery used remote sensing data to obtain building density information using the Normalised Difference Built Index (NDBI) and land use interpretation approaches. With the use of GIS, the spatial distribution of urban vulnerabilities could be known through the overlay of each indicator. The results of the analysis obtained that the physical vulnerability classes of Yogyakarta City were very high (26%), high (29%), moderate (29%), low (16%), and very low (0%). Some areas categorized as vulnerable to very vulnerable are areas with high building density, namely the Sub-districts of Danurejan, Kraton, Gedongtengen, Jetis, Ngampilan, Pakualaman, Mantrijeron, parts of Gondomanan and Tegalrejo.

Abstract
The rate of urbanization has in changes in the urban spatial development, including in the city of Kediri. This study aims to analyze the distribution of urban spatial development in Kediri Regency/City, 2) Analyze the factors the factors that influence the spatial development, and 3) Analyze the UHI phenomenon and its relationship with urban spatial development. This study used Landsat 5 (1996) and 8 (2016, 2021) OLI to analyze Normalized Difference Vegetation Index (NDVI), Normalized Difference Built-up Index (NDBI) and land surface temperature (LST). Ndbi and ndvi are used to determine the urban spatial development, meanwhile lst and ndvi are to analyse surface temperature. The analysis was conducted from 1996 to 2021. Urban spatial development in study area has a linear type along with the development of roads. Built-up land in the study area has increased rapidly in the last 5 years (2016 – 2021) by 83.8% compared to changes that occurred in 20 years (1996 – 2016). This is in line with the increase in urbanization, especially since the advent of the shopping centers. Temperature is increasing in line with the increase in built-up land. There is a potential UHI phenomenon in the study area as indicated by a significant temperature difference between urban and sub-urban. This makes it a challenge for urban spatial planning so that the study area remains a comfortable place to live.

Published: February 2022

Abstract
The distinction between urban and sub-urban becomes faded nowadays. The urban sprawl changes and transforms the sub-urban into more stand-alone cities in many ways, even more with the emergence of various activity centers spread over the area. Intense and complex human activities within the area will affect the micro-climatic condition, such as surface temperature and relative humidity. This study aims to identify changes in air surface temperature in a complex sub-urban area, like the IPB University campus and its surroundings in Cibanteng, Cihideung Ilir, Babakan, and Dramaga, of Bogor Regency. The changes in land-cover over some times also needed to understand, as it will raise the surface temperature, especially when natural vegetation turns into the built-up area. M-AST was generated from regression analysis between ground-based air surface temperature (AST) and image-based land surface temperature (LST). The y = 0.9988x + 4.3082 from the M-AST has an acceptable result with 0.70008 in the R2. The highest air surface temperature was found on the built-up area (35.6 °C), and the lowest was on the non-agricultural area (32.9 °C). This study concluded that the increase in air surface temperature of more than 2 °C was caused by changes in land-cover from vegetation to the built-up area.

Abstract
Urban Heat Island (UHI) explains the occurrence of excessive heat that spread unevenly in urban areas. Intense and complex human activities in urban areas are mainly causing the formation of UHI. This study aims to identify the spatial characteristics of UHI in a complex urban feature, like the Universitas Indonesia campus area and its surroundings in Depok City. The campus and its surroundings might represent a complex urban area and can be used as a reference to understand the widespread impact of UHI. UHI was determined based on the threshold value, calculated from the average and standard deviation of the surface temperature. This study utilized Landsat 8 OLI-TIRS imagery to extract Land Surface Temperature (LST) value. The LST observations were collected for three different periods, including 2013, 2017, and 2021. The LST value tends to be increased during these times, with the LSTmax recorded at 34.68 °C, 35.47 °C, and 36.4 °C for 2013, 2017, and 2021, respectively. Based on the number of the accommodated grid, the UHI was getting larger every year. Started from 313 grids in 2013, the UHI has been expanded to more than 550 grids in 2021.

Abstract
One of Jakarta’s drinking water sources, the Krukut River, has been contaminated by a variety of industrial and domestic wastes, including microplastic pollution. To investigate the abundance and identify the of microplastics in the Krukut River, water and sediment from 3 sites, upstream, middle and downstream were collected using a water sampler and Ekman sediment grab sampler, respectively. The microplastic from water and sediment was extracted using density separation method. The microplastics were counted and categorized according to the shape under a microscope. The differences in microplastic abundance in three different sites were determined using a one-way ANOVA. The result shows fiber dominated microplastic shape in the water across the sampling sites, whereas pellet dominated microplastic shape in the sediment from upstream to middle-stream. The downstream water has the highest abundance of microplastics (265 ± 5.0 particle/100 mL), which is significantly different (p<0.05) from the middle (221 ± 3.0 particle/100 mL) and the upstream (215 ± 1.5 particle/100 mL). Similarly, the downstream sediment had the largest abundance of microplastics (150 ± 5.0 particle/kg dry weight), which was significantly different (p<0.05) from the middle (125 ± 6.0 particle/kg dry weight) and the upstream (112 ± 3.5 particle/kg dry weight).

Published: February 2022

Abstract
We analyze the problems of using waste products of the forestry sector for energy purposes with the central ecological zone of the Baikal natural area as the case study. From the standpoint of the energy sector, the two main problems that hinder the spread of wood fuel are discussed: pricing and transport of the end product. From the standpoint of the forestry sector, the main problem is the transport of wood from logging sites. We investigate the influence of the annual amount of wood feedstock at wood processing enterprises on the optimal method of wood waste recycling. It is concluded that, at present, wide adoption of fuel pellets and wood chips proves impossible unless supported by state measures.

Published: February 2022

Abstract
In the article, the authors investigated a device for testing the insulation of electrical equipment with increased voltage. Insulation in electrical devices is an essential design element. The dielectric strength of the insulation is determined by its ability to withstand the continuous rated voltage for which the installation is designed. But in some cases, the strength of the insulation may deteriorate due to moisture or defects. Defects can be air inclusions in solid or liquid dielectric. These air inclusions further create conditions for the occurrence of partial discharges. The article discusses the test schemes that exist today to determine the margin of dielectric strength of insulation. The article presents a diagram of the developed device of the installation for testing insulation based on a single design and technological component. The presented device has a smaller weight and size and more effective voltage gain. The results of mathematical modeling, proving an improvement in gain in comparison with analogs, are given.
