Abstract

The accuracy of land use and management affects the watershed's or sub-watershed's health, especially upstream. The Lesti sub-watershed in Malang Regency is the upstream part of the Brantas watershed; their land use pattern is always associated with erosion rates, which impact sedimentation in the middle and downstream. When discussing erosion, the rate increase is generally influenced by erodibility, erosivity, length/gradient of the slope, and plant factors/conservation measures. Population pressure has not been discussed much, although the erosion rate affecting sedimentation in the Sengguruh Reservoir as an outlet for the Lesti Sub-watershed has much to do with the Population's activities. People's activity and choice of land use put pressure on the land, affecting the watershed's carrying capacity. Measuring the land's carrying capacity is usually known from the value of existing population pressure and its effect on vulnerability or Erosion Hazard Level (EHL). This study attempted to assess the relationship between erosion hazard levels and population pressure and determine conservation priority areas in the Lesti sub-watershed. This research method was carried out quantitatively, which involved calculating the analysis of population pressure and the EHL obtained spatially from the erosion rate of the Modified Universal Soil Loss Equation (MUSLE) and soil solum. The results showed a similar wedge between high population pressure and severe EHL. This Area is recommended as the most priority location for conservation policies in the Lesti sub-watershed.

Abstract

Corruption in Indonesia's natural resource sector is a significant issue with far-reaching consequences for environmental sustainability. Despite the detrimental effects of corrupt practices on the environment, law enforcement penalties for corruption often fail to compensate for their environmental impact. The aim of the study is to explore how the use of Environmental Impact Assessments (EIAs) strengthens law enforcement efforts and increase penalties for corrupt practices in Indonesia's natural resource sector. The method used is to collect and analyze regulations, policies, and corruption study cases to examine the relationship between EIA and corruption penalties. The results showed that EIA can help corruption cases investigation and corruption cases involving EIA receive heavier penalties. This study concluded that the Indonesian government needs to reformulate its law enforcement approach by incorporating EIA into corruption investigations and using more severe penalties to deter corruption in the natural resource sector.

Abstract

Background: Landslides are one of the most dangerous geological disasters in the world due to the movement of earth material caused by gravity. Landslides also threaten the environment, property, and human life risks in high-risk areas. This study compares how landslide characteristics impact evacuation planning in Indonesia and various other countries. Methods: Utilizing a Systematic Literature Review (SLR) of studies published between 2019 and 2024, this research examines landslide characteristics that prompt community evacuation responses, such as landslide triggers, physical conditions, and the number of people affected. Findings: Findings reveal that while Indonesia and other high-risk countries face substantial landslide risks, challenges remain in enhancing disaster preparedness, including evacuation planning to minimize casualties. Physical characteristics and the preparedness of early warning systems are crucial in shaping community responses to landslides. This case study illustrates how a combination of steep slopes over 40 degrees, heavy rainfall intensity of more than 200 mm in one week, weak soil textures, and dense vegetation can trigger devastating landslides. However, landslides triggered by seismic activity result in significantly higher fatalities, and special attention is needed in areas prone to landslides and earthquakes, as happened in Nepal (highland and mountainous climate). In China (subtropic region), landslides are primarily triggered by moisture-saturated soils, which are vulnerable to ground motion, particularly during prolonged rainfall. In Indonesia as tropical region, landslides triggering evacuation predominantly occur in areas with highly erodible and unstable soils, exacerbated by high rainfall. Conclusion: Evacuation planning must be more adaptive and supported by GIS technology to identify high-risk areas. Globally, evacuation success relies on infrastructure, community awareness, and disaster preparedness. Novelty/Originality of thid article: This study highlights the importance of crisis management strategies tailored to the specific landslide characteristics of each region, as well as the crucial role of community involvement and technology in ensuring effective evacuations.

Abstract

As a country prone to hydrometeorological disaster and demographic problems, Japan is very concerned about integrated watershed sustainability, as a preventive and sustainable water resource in the future. In contrast to Indonesia, the rapid population growth encourages various activities in the upstream such as encroachment, conversion to agricultural land, settlements, and other economic activities causing land degradation and environmental quality to decline. The critical watershed recovery program has been carried out for a long time, but until now this problem has not been resolved. This study aims to determine the best integrated watershed management system that can be applied to accelerate the recovery of critical watersheds in Indonesia. This study uses a qualitative approach, with a comparative descriptive method to compare watershed management in Japan and Indonesia based on a literature study. It was found that land rehabilitation activities through replanting upstream watershed areas require collaboration in comprehensive and integrated management from upstream to downstream. The practice of inter-regional cooperation and community involvement through cross-subsidized funding and joint restoration activities is a scheme that needs to be considered for accelerating watershed recovery, accompanied by the integrity of the parties and a transparent and accountable monitoring system.

Abstract

Electric vehicle (EV) is an alternative expected to be tail-pipe emission-free and improve public health. Switching conventional or internal combustion engine vehicles (ICEVs) to EVs becomes a potential strategy for realizing urban sustainability. The study aims to review the environmental impact between ICEV and EV in Lithuania, China, Canada, Poland, Czech Republic, Italy, United States, and Australia. Then, the review result is compared to the Indonesia context as lessons learned. A comparative study with a qualitative descriptive method was carried out. The main activities are a literature review. The works of literature were collected, classified, and reviewed to find out significant findings on the environmental impact of ICEV and EV. Assessing the vehicle in all life-cycle (LC) phases is an essential issue. The entire LC of products may significantly impact the environment due to the utilization of raw materials through a process that causes adverse environmental impacts. Therefore, Life-cycle assessment (LCA) is proposed to estimate the environmental effects related to all the LC stages of EVs. Thus, LCA could be a critical tool. Numerous cases in several countries show that EVs were not always more environmentally friendly than ICEVs. The review indicates that EVs and electricity-generating mix scenarios play a significant role in performing LCA due to the performance of an EV is extremely dependent on the energy consumed through its operation phase. Additionally, the results show how significant renewable energy sources (RES) are in the electricity-generating mix that provides different environmental impacts. In the Indonesia context, the environmental impact of EV is predicted to be higher than ICEV due to the electricity generating mix is still lower than 20% in 2023. Optimizing the electricity generating mix scenario by increasing the RES, implementing clean technology power plants, and applying vehicle recycling are excellent strategies to promote sustainable development in the EV industry. However, economic and social aspects shall be considered to get comprehensive results in further research.

Abstract

Waste that has a high organic matter content can be treated biologically under anaerobic conditions or using bacteria that can live in an environment without oxygen. One method of wastewater treatment that can reduce high organic content is the Fixed Bed type anaerobic reactor system. The purpose of this research is to compare the treatment of organic wastewater using a Fixed Bed type anaerobic reactor that has been implemented in Germany with that implemented in Indonesia. The method used is a literature study by comparing case studies between the two countries, so the methodology used is a systematic literature review. Based on the results of the discussion, it is known that the organic waste that is processed using an anaerobic reactor carried out in Germany has several differences starting from the sub-stages of the process, and operations to the materials used such as the use of pumps, installation storage tanks, sewage filtration, use of stainless steel and heat exchangers. These differences if applied in Indonesia can cost relatively a lot so they are not suitable for application in Indonesia. Based on the literature study, it was concluded that the anaerobic wastewater treatment solution using a fixed bed type in Indonesia can be a good opportunity and can be imitated by other countries because it has simple equipment, but the reactor efficiency and the resulting percentage of methane production are relatively high. although the required HRT is long, anaerobic catalysts can be used as a solution.

Abstract

The increase in earth's surface temperature for 2001 - 2020 was 0.99oC with the highest increase in 2011 - 2000, namely 1.09oC, which was higher than 1850 - 1900. Awareness has emerged from several countries worldwide about the dangers of increasing GHGs due to climate change, so countries have gathered to discuss climate change at international conferences. This conference is known as the Conference of Parties (COP). The Indonesian government is committed to reducing carbon emissions by 29% independently and 41% with international assistance by 2030 so that the earth's temperature does not increase beyond 2°C. Vietnam ratified the Paris Agreement and committed unconditionally to reduce by 8% GHG emissions by 2030 relative to business as usual (BAU) levels and aims to achieve a 25% reduction subject to international support. This research aims to compare the policies of the Indonesian and Vietnamese governments to achieve land sector GHG emission reduction targets. This research will analyze Indonesia and Vietnam's policies, strategies, and implementation in reducing land sector emissions. The research method used was a qualitative approach.

Abstract

Disaster management planning is an activity that is translated into documents to be used as a reference in carrying out disaster risk reduction.. Furthermore, based on data from UN-ESCAP for 2022, disaster events in Indonesia dan Bostwana are dominated by extreme weather, especially storms, floods and droughts. so that disaster management planning, especially for flood disasters, is considered important as one of the efforts to reduce disaster risk. This study aims to compare the evaluation results of the disaster management planning documents owned by Botswana and Indonesia. This study uses a systematic literature review method and a comparative study with a qualitative descriptive approach to evaluation of disaster management planning between Gaborone, Botswana and Yogyakarta, Indonesia. The results of the research show that the evaluation of disaster management planning in Gaborone City, Botswana still requires updating and involving the public more in the preparation of this document. In addition, the results of the evaluation of disaster management planning documents in the City of Yogyakarta, Indonesia still require efforts to integrate disaster documents with other planning documents so that they can become a reference for the implementation of disaster risk reduction activities by various stakeholders involved in the disaster sector. The problem with disaster management planning documents in the two countries is the lack of public involvement and the lack of integration of this disaster management planning document with other development planning documents, including issues regarding validity periods. The offered solution is to update the disaster management planning document by involving more public argument.

Abstract

Due to worries about global warming and its effects on the environment, economy, and society, a lot of emphasis has been paid to the switch to electric vehicles (EVs). This essay focuses on the switch to electric vehicles in Indonesia and Russia. Green technology, such as EVs, have been introduced in Indonesia in order to lower carbon dioxide (CO2) emissions and enhance air quality. The study emphasizes the advantages of EVs, including their simplicity and improved comfort when compared to conventional vehicles, as well as their free highway use, parking, and tax incentives. The restricted affordability, ambiguous national policies, and inadequate public infrastructure provide difficulties for Indonesia. However, relative to its enormous auto fleet, Russia has lagged behind in the development of EVs, with just a tiny number of registered electric vehicles. However, the Russian government has approved a plan to increase the infrastructure and production of electric road transport. The strengths, weaknesses, and transitional strategies for EVs are assessed using a case study approach and comparative analysis. In order to encourage the use of EVs, it is stressed the significant of incentive programs and supportive policies, such as tax breaks and regional manufacture.  The study comes to the conclusion that although both nations have made progress in the transition to electric vehicles, more has to be done in terms of policy creation, infrastructure development, and technological improvements in order to hasten the adoption of EVs in Russia and Indonesia.

Abstract

Global trends in electric vehicle adoption have been increasing significantly in recent years. In Indonesia, the government has issued various policies to encourage the use of electric cars. However, anticipation of the environmental impact of this program has not yet received serious attention. Current regulations regarding battery waste management still refer to existing regulations governing hazardous and toxic waste. This study aims to forecast the potential of battery waste from electric cars in the future and provide policy recommendations to establish a sustainable electric car program. The methods of analysis employed include material flow analysis and policy content analysis. Based on three scenarios (low, medium, and high adoption scenarios), the analysis results show a significant increase in battery waste in all scenarios from 2025 to 2040. The increase in active materials, aluminum, and copper waste could exceed 50 times during this period. Electrolyte, plastic, and steel waste also increase substantially, with growth reaching 3050 times. Although relatively small in volume, rare earth metals are projected to rise 19 times. By 2040, the potential of battery waste is estimated to reach 1,998,911 tons in a low adoption scenario, 2,600,540 tons in a medium adoption scenario, and 3,170,517 tons in a high adoption scenario. The result of policy content analysis of the electric vehicle regulations issued by the Indonesian government since 2019 demonstrates that efforts to enhance electric vehicle adoption will become the main focus for the government in the coming years. A thematic mapping of policies related to 20 electric vehicle regulations published during this period reveals that only three regulations address environmental issues. This study indicates the need for policy improvements by formulating specific derivative regulations that govern electric car battery waste management.
