Abstract

Every household produces used cooking oil as waste that has no economic value. Some people still dispose of used cooking oil into water channels and soil, due to a lack of insight into the impact of this behavior on the environment. The Ngudi Lestari Waste Bank in Tinjomoyo Village became an educational place for the community to understand the importance of managing used cooking oil and providing economic opportunities for the community. This study aims to identify the characteristics of used cooking oil management at the Ngudi Lestari Waste Bank, describe the use of technology in the process of managing used cooking oil and wax at the Ngudi Lestari Waste Bank, analyze the economic value of used cooking oil management and strategies that can be developed to expand the network and use of technology in the management of used cooking oil at the Ngudi Lestari Waste Bank. The analysis was carried out using the recognition survey method, descriptive analysis, cost and return, transaction cost, and triangulation. It was found that they do not use any technology from the collection to the marketing stages in the Ngudi Lestari Waste Bank system. Strategies such the use of online questionnaires, collaborating with third parties, using e-commerce platforms to utilizing social media in marketing aspects can be used. Overall, the management of used cooking oil at the Ngudi Lestari Waste Bank not only contributes to the environment but also provides economic benefits to improve the economy of local residents. Keywords: management, strategy, used cooking oil, utilization of technology, waste bank

Abstract

Research Originality: This study enriches the environmental efficiency literature by applying a DEA model that considers undesirable outputs, to produce more comprehensive and accurate efficiency estimates, especially in the context of the ASEAN region Research Objectives: To evaluate and compare the relative environmental efficiency of ASEAN countries using the Data Envelopment Analysis (DEA) method Research Methods:  This study applies the DEA approach to measure environmental efficiency in ASEAN countries from 2000 to 2022, using population and industry as inputs, and GDP and CO2 emissions as outputs Empirical Results: The findings indicate variations in environmental efficiency among ASEAN countries, reflecting differences in industrial policies and levels of economic development. Singapore emerges as the most efficient country, while Indonesia is identified as one of the ASEAN countries that needs to focus on improving its environmental efficiency. Implications: The research results show significant variation in environmental efficiency across ASEAN countries. This finding emphasizes the importance of formulating development policies that are not solely oriented toward economic growth but also address resource efficiency and emission reduction. Countries with low efficiency, such as Indonesia, need to develop more comprehensive, data-driven green transition strategies. JEL Classification: C31, G21, I32, O18 How to Cite:Kusumawardhani, H. A.

Abstract

This study aims to identify the relationship between economic growth, renewable energy, and industrial value added to CO2 emissions in ASEAN. The data used is panel data of 10 ASEAN countries from 2001-2020. This study uses the vector error correction model (VECM) for analysis. The estimation results show that CO2 emissions are only influenced by the CO2 variable itself in the previous period in the short term. In addition, economic growth and renewable energy significantly negatively affect CO2 emissions in the long term. Economic growth has the largest contribution to reducing CO2 emissions. The empirical findings also support the existence of the environmental Kuznets curve (EKC) in ASEAN. However, industrial value added has no significant effect on CO2 emissions. This study has several policy implications. The government needs to 1) strengthen energy transition regulations to encourage the use of renewable energy, 2) increase investment in RD to stimulate green technology innovation, and 3) protect the environment to mitigate negative externalities of economic activity.

Abstract

This study aims to identify the vulnerability of small-scale fishermen in the Roban Coastal Area through fast variables and slow variables, identify the adaptive capacity of fishermen to social-ecological changes, and analyze the resilience strategy of fishermen in facing rapid social-ecological changes due to national strategy projects. The method used was a mixed method with descriptive statistical analysis and 100 small-scale fishermen were taken as samples through purposive sampling. The results obtained show that the level of vulnerability of small-scale fishermen is in the high vulnerability category with a score of 7.89, the most vulnerable indicator is dependence on nature. The Roban Coastal small-scale fishermen resilience strategy is carried out through interdependence between stakeholders (academics, business people, government, and community) by obtaining the results that need to pay attention to several aspects (social, environmental, economic) in facing changes so that fishermen have a resilient level of resilience.
