Abstract
Landslides in geothermal areas are one of the environmental challenges that are attributed to their volcanic and hydrothermal systems. However, the inventory of landslides in geothermal areas remains considerably limited. This may implicate pitfalls, where characterisation of historical events is an essential practice in disaster risk management. Accordingly, this exploratory study aims to characterise landslide events in 19 geothermal areas with historical landslides. This introductory study was sourced from electronic news, scientific publications, and authoritative institutions. The collected records were cross-examined and integrated into comparable attributes. The resulting characteristics display the physical features, environmental factors, and mitigation measures as follows: (1) landslides commonly occur in small to extremely large volumes. However, serious tolls may be caused even by small-to modest-sized landslides. (2) Landslides may not be preceded by triggering factors but by their gradually weakened environment. (3) Although there are scattered sources and unclear information related to underreported landslides and understudied mitigation, respective authorities conduct rapid measures following the landslide event. Correspondingly, it is highly recommended to further improve and establish a landslide inventory database in geothermal areas that constitutes a more comprehensive overview for better risk management.

Published: December 2023

AbstractIndonesia is the largest garlic importer in the world, relies on imports for over 95% of its garlic needs. To address this import dependence and meet domestic demands, the Government initiated the National Garlic Development Program. However, the program has yet to achieve the targeted production, even the development of garlic faces many obstacles that threaten its sustainability. The objectives of this study are as follows: (1) to determine the sustainability status of garlic production based on the dimensions of sustainability, and (2) to identify the leverage factors for the sustainability of garlic farming. The research location was purposively selected in Temanggung District, Central Java, which is Indonesia’s largest garlic production center. The sustainability status of garlic production was analyzed using multidimensional scaling (MDS). The results indicate that garlic production exhibits a less sustainable status across multiple dimensions. The identification of leverage variables, suggested interventions involve the following measures; enhancing irrigation systems and minimizing reliance on chemical fertilizers, providing price and marketing guarantees, reducing farmers’ dependency on subsidies, expanding the cultivated land through the application of advanced technologies for mass production of superior seeds, strengthening the involvement of agricultural extension officers, fostering consumer preferences and farmers’ engagement in garlic cultivation.

Abstract
The most widely produced agricultural commodities in Indonesia are oil palm and paddy crops, which contribute the most to national income in the agricultural sector. On the other hand, in 2020, the agricultural sector contributed 9% to national greenhouse gas (GHG) emissions. This study aims to determine the effect of agricultural crop production, namely oil palm and paddy on GHG emissions in Indonesia’s agricultural sector from 2000-2020. Data for the study were obtained from the Directorate General of Climate Change, the Ministry of Environment and Forestry and BPS-Statistics Indonesia. The GHG effect of agricultural crop production were analyzed using multiple linear regression. The findings showed that the production of oil palm and paddy crops significantly affects the agricultural sector’s GHG emissions. Oil palm and paddy production have a significant level of 5% with a regression coefficients of 0.4958 and 0.0003, respectively. From the findings, it can be implied that an increase in oil palm and paddy production will raise Indonesia’s agricultural sector GHG emissions. The government can draw up regulations related to (1) protecting forest areas and peatlands close to community residential areas so that land conversion does not occur in oil palm plantations and (2) a sustainable agricultural system to increase paddy productivity, hoping that the agricultural sector’s GHG emissions will decrease.

Abstract
The Covid-19 pandemic has generally impacted coastal activities, including mariculture development. A decrease or increase in aquaculture production will influence the aquatic environment and socio-economic of coastal communities. The aims of this study were (1) to analyze mariculture production in Ekas Bay during the Covid-19 pandemic and (2) to evaluate the coastal management based on the coastal community perspective. The study analysis uses both of analysis of comparative and analysis of descriptive. The results showed that the number of floating marine cages and fishery production had increased by more than 500% during the pandemic compared to before the pandemic. From the results of the dept-interview with coastal communities and fisheries extension officers, one of the drivers for increasing the amount of marine production, especially lobster commodity, is the implementation of government policies related to lobster management. Coastal management implementation has a good category with 65,03% of response assessment. The study also evaluated household waste management, resulting in a poor category with 56.65% of respondents’ assessment. Household waste needs managed properly to minimize the risk of environmental degradation and decrease marine resources in Ekas Bay.

Published: December 2023

Abstract
Emissions from transportation activities can cause GHG effects, which cause an increase in city air temperature. The city of Bogor is working on processing BisKita as mass transportation, which is considered more environmentally friendly than public transportation (Angkot). This study aimed to analyze the basic conditions of climate-related transport emissions before and after BisKita and formulate good practice options for reducing emissions. The research was conducted in Bogor, West Java Province, focusing on public transportation and BisKita, which had not yet operated on the K3 (Ciparigi – Ciawi) and K4 lines (Bubulak – Sukasari Bus Terminal via Surya Kencana). The resulting emission value is obtained by calculating the vehicle emission value with the factors of route length, number of fleets, and total fuel consumption. The formulation of good practice options is generated for implementing low-emission transportation that is more environmentally friendly by analyzing various transportation policy literature that originates from literature studies. The analysis showed that angkot emissions could be reduced by 18.6% on the K3 route and by 14.8% on the K4 route as a reduction strategy (three angkot:1 bus) with BisKita as mass transportation. Bogor can implement various green transportation transitions and operational plans from other countries and cities in Indonesia.

Abstract
Flash floods are catastrophic phenomena known for their rapid and unpredictable occurrence. They frequently display precursory indicators, which, when comprehensively studied, serve as vital clues for effectively anticipating and preparing for these events, thus reducing their adverse effects. This study aimed to investigate the key trigger factors contributing to a flash flood event in the upper Ciliwung Watershed in January 2021. Data collection involved various parameters, including morphology, precipitation patterns, land use, hydrological characteristics, and soil conditions collected from the affected area. These data were subsequently analyzed using geospatial methods and enriched with information from local community members. The analysis found multiple contributing factors to flash floods, including high soil moisture content due to prolonged precipitation, geological characteristics, and steep topography. The local community recognized landslides, creating a natural dam about a month before the flash flood. Unfortunately, inadequate measures were taken to address the flood due to limited understanding and resources. The heavy rainfall before the flash flood put immense pressure on the natural dam, causing it to fail and carry debris downstream. The steep banks of the surrounding river worsened the situation. The study’s findings can provide valuable insights for local authorities, leading to better resource allocation.

Abstract
Despite previous reports of contamination from domestic waste, agricultural runoff, and fertilizers, shallow groundwater (GW) within Bandung Regency remains a clean water source. Nitrogen is one of the most common contaminants identified in the region. This study aims to assess nitrogen concentrations and determine the groundwater pollution index (GWPI) caused by nitrogen. The GWPI categorizes water as excellent water (GWPI <0.5), good (0.5< GWPI <0.75), moderately polluted (0.75< GWPI <1), and highly polluted (GWPI >1). Twenty-seven GW samples were collected during the wet season in October 2022, and physicochemical parameters were analyzed, including pH, dissolved oxygen, GW temperature, electrical conductivity, total dissolved solids, oxidation-reduction potential, dissolved iron and manganese, ammonium, nitrate, and nitrite. According to the analysis, there was a significant variation in the dissolved inorganic nitrogen (DIN), with 12 samples dominated by ammonium and 15 samples dominated by nitrate. The GWPI calculation ranges from 0.96 to 3.52, indicating that 33% of the samples exhibit excellent water quality, 19% show good water quality, 22% demonstrate moderately polluted water, and 26% demonstrate highly polluted water. Based on the spatial distribution analysis, it was found that the settlement exhibited the most substantial levels of GW pollution due to DIN.

Authors: Georgiou Kyriakos E 
Published: December 2023

Abstract
Forest fires and wildfires are increasing in many regions of the world and give the big impact on the environment, local economies, livelihoods, and societies. Cyprus is an island member of the European Union in the south-eastern Mediterranean and it is severely affected by wild fires. The aim of this paper is to review the pertinent, recent literature (which although not exhaustive, identifies the main contributing factors) mostly in the Mediterranean region and to identify the variables that affect the rise in the number and intensity of forest fires, wildfires and how these variables are affecting Cyprus. This research was conducted by using statistical data made by the Cyprus Statistical Service. By compiling the data of climatology, demography, agricultural production, and forest fire incidents, some results were found. The increased forest fires were caused by the rise of the average annual mean temperature in the period of 1990-2021, the change in social conditions and agricultural land use with the urbanization of people living around the forest areas, and the conservative policies adopted by successive administrations with reference to forest management and conservation.
Studies on flood disaster causes in DKI Jakarta Province
Authors: Nurjayati Ratih , Mbarep Daniel Putra Pardamean 
Published: December 2023

AbstractFlood is a disaster that occurs in almost regions of Indonesia, including DKI Jakarta province. From 2016 to 2020, there were more than 50 flood events in DKI Jakarta province. Several previous studies mentioned various factors that could cause flooding in DKI Jakarta province, including rainfall intensity, sea surface level, land surface level, and land use changes. This study aims to analyze and find out the main factors that cause floods in DKI Jakarta province. The data obtained from processing the interpretation of satellite imagery and literature review were then analyzed using a quantitative descriptive method with the Pearson correlation test to determine the coefficient value and the level of correlation/relationship between variables. The results showed that the rainfall intensity has a value of 0.968, the land use changes factor is 0.138, the land surface level factor is 0.095, and the sea surface level factor has a value of 0.051. Rainfall intensity has the highest value, with a strong correlation/relatedness to flood events. Land use changes, land surface level, and sea level have a shallow correlation/relationship to flood events. Thus, the rainfall intensity is the main factor causing flooding in DKI Jakarta province.
Delonix regia as a climate bio-indicator: The effect of climate change on flowering time in Kupang, East Nusa Tenggara
Authors: Fanggidae Y R , Ramadhani F 
Published: December 2023

Abstract
The study of climate bio-indicators, such as the flowering time of plants, can provide valuable insights into the effects of climate change on the environment. In this study, we investigated the impact of climate change on the flowering time of Delonix regia in Kupang, East Nusa Tenggara. Delonix regia trees at 50 points were observed, and their flowering time was determined in monthly time series between 2013 and 2022 using the Normalized Difference Vegetation Index (NDVI) technique with Landsat 8 satellite imagery. The NDVI criteria for determining flowering were verified through real-time observations during the flowering season in 2021 – 2022 and confirmed using Google Earth imagery. The study’s findings indicate that Delonix regia trees in Kupang previously mass-flowered (> 75% of the population with 65 – 100% closure of the canopy area) once a year in November – December over the past decade, but the flowering time is now changing. Some observed trees in 2021 and 2022 flower twice a year, in April – May and November – December, causing flowering not to close the canopy as in previous years fully. Changes in temperature and rainfall affect the timing of flowering. Increased rain in February-March-April 2021 and 2022 (> 65 mm from the climatology 1990 – 2020) and warmer annual average temperature conditions are thought to trigger flowering initiation, which suggests that climate change significantly impacts the local environment. Our results demonstrate the potential of Delonix regia can be one of the climate bio-indicators and emphasize the importance of monitoring the flowering times of plants.

Published: December 2023

Abstract
Climate change has had a significant impact on regional climate in many countries, including Indonesia. The coastal sector is one of the most vulnerable to climate change. Pekalongan City is one of the most vulnerable coastal areas in Indonesia to the effects of climate change. Tidal flooding is a disaster that occurs in coastal areas due to rising sea levels, which average 6-10 mm per year on Java’s northern coast. Tidal flood hazard analysis was performed using indicators of sea-level rise, distance to the sea, distance to the river, slope, topography, land cover, and land subsidence. The results of the field validation were consistent with those of the tidal flood hazard analysis. Areas covered by the tidal flood hazard modeling include Pasirkratonkramat, Bandengan, Kandang Panjang, Panjang Baru, Panjang Wetan, Krapyak, and Degayu. Pekalongan City experienced an increase in hazard area of 6.18% of the total area of Pekalongan City based on the results of the CSIRO modeling RCP 4.5 scenario. In comparison, the other three models show a decrease of up to 3.13% in the total area of Pekalongan City. However, when viewed at the site scale (per urban village), Podosugih Village experienced the highest increase in hazard area, up to 20.5% of the total area for the CSIRO-modeled RCP 4.5. The highest decrease in the area occurred in Klego Village, at 8.94% of the area for the RCP 4.5 scenario of the MIROC model. Future changes in rainfall, sea level, and land subsidence will cause these changes.

Published: December 2023

Abstract
West Java has excellent potential in hydropower energy development, partly because it has high-intensity rainfall. However, some things could be improved with the water supply to produce electricity, mainly due to rainfall and temperature variability. Therefore, it is necessary to analyze the magnitude of the contribution of climate factors to the availability of hydropower energy, as well as the sensitivity of the total potential loss of water supply due to variability and changes in rainfall and temperature. Data analysis was carried out by modeling the impact of rainfall and temperature on the availability of power supply for hydropower operations. The results show that rainfall greatly contributes to the loss of hydropower supply with an R2 value of 0.9. However, the temperature does not contribute to the Cirata and Saguling hydropower plants, seen from the R2 value of only 0.03. In contrast, for the Kracak hydropower plant, the temperature contributes to the loss of power supply with an R2 value of 0.7. Loss of power supply in 2021 to 2040 will tend to be higher and occur more frequently than the observation year, with the highest potential loss of 1 MW (5%) at the Kracak, 300 MW (29%) at the Cirata, and 300 MW (42%) ) at the Saguling. The total potential loss of power supply for the Kracak, Cirata, and Saguling hydropower plants is sensitive to changes in rainfall and temperature in these areas.
