Abstract

Industrial development in Indonesia has been predominantly concentrated on Java Island, particularly in Karawang Regency, West Java Province. Covering an area of 175,327 hectares, Karawang has been identified as a strategic region for national food security. The Minister of Agrarian Affairs and Spatial Planning designated 95,667.45 hectares of rice fields as protected agricultural land. However, the expansion of industrial and residential areas within the regency poses a significant threat to its role as the national rice granary and to broader food security. As industrial land occupancy increases, the environmental capacity to support rice production and ensure national food security declines. This study aims to assess the environmental impacts of land use changes in the industrial zones of Karawang Regency for 30 years. Spatial imagery data were processed using supervised classification techniques to Landsat 5 and Landsat 8 TM level 1 geocoded imagery. The environmental impacts were analyzed using Geographic Information Systems (GIS) and further supported by in-depth interviews concerning flood events that occurred over the past five years. The multiple regression analysis was conducted to evaluate the influence of environmental, economic, and social factors on flood impact losses. The results indicated that 55.6% of the variation in flood impact losses could be explained by the combined effect of the three independent variables. The findings revealed substantial land use changes over the past 40 years, with approximately 38,571 hectares (22%) of vegetation and water bodies were lost and replaced by industrial and residential developments, which increased by 31,558 hectares (18%). A strong correlation was observed between land use changes and the environmental impacts of flooding in Karawang Regency. Accordingly, it is recommended that local government implement measure to regulate land conversion to mitigate further environmental degradation. An integrated spatial planning approach that incorporates ecological considerations, is strongly advised to reduce the risk of flooding in industrial areas

Abstract

Theory of Planned Behavior (TPB) has been widely applied in environmental science as it closely linked to human behavior. This study aims to analyze research trends, identify potential future research, and propose the development of an integrative TPB model to address gaps in previous research. A total of 120 articles were selected from the Scopus database using rigorous screening criteria, including title-based selection, English-language articles, and a manual abstract review, covering publications up to April 4, 2025. Bibliometrix, VOSviewer, and MindMup were used to support keyword visualization and content interpretation. The results show that China and the United States lead in research contributions, while Africa, despite facing significant sustainability challenges, remains underrepresented. Recent research topics include energy efficiency, climate change, and air quality, which are different from the topics of interest before the COVID-19 pandemic, such as green hotels and tourism. Keyword such as “corporate norm” appear less integrated with other research themes. Further researches are expected to focus more on Africa and incorporate additional behavioral frameworks. In particular, integrating with behavioral models based on altruistic interests (Value-Belief-Norm/VBN), especially for studies in the Asian regions, which have a more dominant collectivist culture than individualism. The weakness of TPB, which only considers cognitive factors, can be addressed by adding affective factors through the Model of Goal-Directed Behavior (MGB). The proposed integration of MGB-VBN-Knowledge holds potential to enhance explanations of public environmental behaviour and formulate more effective policies. The role of corporate norms in shaping environmental behavior also warrants further exploration.

Abstract

Mangroves play a crucial role in maintaining the stability of coastal ecosystems by providing habitats for diverse species, protecting shorelines from erosion, and acting as a carbon sink. The importance of conserving and developing mangrove areas can be effectively monitored using remote sensing data and classification methods, such as Random Forest (RF), ensuring an accurate assessment and management of these vital ecosystems. This research aims to develop and evaluate an RF classification model to produce accurate spatial information on mangrove canopy cover. The research area, Benoa Bay in Bali, Indonesia, is known for its dynamic and ecologically complex mangrove habitats. The inputs for RF classification are bands on Sentinel-2A satellite imagery, Mangrove Vegetation Index (MVI), Normalized Difference Vegetation Index (NDVI), Enhanced Mangrove Index (EMI), Modified Normalized Difference Water Index (MNDWI), Normalized Difference Moisture Index (NDMI), and the Normalized Difference Salinity Index (NDSalI), along with topographic variables such as elevation and slope. Model validation was conducted using high-resolution imagery from Google Earth Pro and cross-referenced with the 2024 National Mangrove Map. The classification of coastal land cover is divided into water bodies, mangroves, open land, built-up land, and non-mangrove vegetation, with an overall accuracy of 0.98 and a kappa statistic of 0.98. In contrast, the accuracy of the classification of mangrove canopy cover concerning the national mangrove map produces an overall accuracy of 0.97 and a kappa value of 0.86. These findings demonstrate the robustness of the RF model and its potential for supporting data-driven coastal management practices.

Abstract

DKI Jakarta as the capital of Indonesia has a policy to manage waste (recycling) in a decentralized manner, namely that waste is managed as close as possible to its source, without relying on disposal in landfills anymore. This pro-environment policy targets reducing and handling waste by 30% and 70% respectively by 2030. Currently the program is being implemented, non-residual waste will be processed and recycled in decentralized processing or TPS 3R. In order to achieve this target, the community and government must work together to make changes and must have a sense of ownership, responsiveness, concern and responsibility for the waste produced. This research uses a qualitative approach with observations, questionnaires to 330 respondents and interviews with the community and local government. And this research found that TPS and TP3R public facilities still do not comply with existing regulations and do not meet the criteria for accommodating recycling activities. From 2018-2022, the reduction in waste generation was 9% from the target of 26% and the amount of waste handling was 1.66% from the target of 70%. People still don't recycle for various reasons and there is also a lack of consistency in implementing recycling behaviour due to rational attitudes such as just paying money for waste. The government is obliged to facilitate these recycling activities together with various stakeholders, by carrying out various innovations and outreach to the community, by implementing waste management based on community participation.

Abstract

The intensive use of pesticides in agriculture has raised concerns regarding environmental quality and economic sustainability, particularly in Parongpong District, West Bandung Regency. This study aimed to analyze the impact of pesticide use on soil and water quality as well as its economic implicates on farmers. A mixed-method approach was applied through soil and surface water sampling, laboratory analysis, and structured questionnaires with 100 farmers. Soil quality tests revealed low pH, reduced organic carbon (1.61%), and high cadmium (5.2 mg/kg), indicating soil degradation. Water samples from the Cibeureum River showed that BOD (93.5 mg/L), COD (302 mg/L), and total phosphorus (0.475 mg/L) exceeded national standards, suggesting nutrient overload and pollution linked to pesticide runoff. Economically, although 98% of farmers perceived pesticides as beneficial, the Benefit-Cost Ratio (BCR) analysis resulted in a value of 0.57, implying financial inefficiency. This indicated that the cost of pesticides and mitigation outweighs the actual benefits received from increased crop yields. The gap between farmers’ perception and objective economic and environmental data highlights the need for sustainable solutions. Organic farming practices introduced by local farmer groups, such as Semai Organik and Farm Organic Parongpong, offer promising alternatives for improving productivity while preserving environmental integrity. Promoting environmentally friendly farming methods is essential to ensure long-term ecological balance and economic resilience in the agricultural sector.

Abstract

Di wilayah perkotaan dengan kepadatan tinggi seperti Jakarta dan sekitarnya, proses urbanisasi dan pertumbuhan industri yang pesat telah menyebabkan pengambilan air tanah secara berlebihan serta penurunan kualitasnya. Berbagai polutan seperti nitrat, hidrokarbon dari minyak bumi, mikroba, dan bahan kimia beracun kini mengancam akuifer dan persediaan air bersih. Penelitian ini bertujuan untuk melakukan penilaian spasial terhadap tingkat kerentanan intrinsik air tanah di Cekungan Air Tanah Jakarta dengan menggunakan model DRASTIC dan Sistem Informasi Geografis (SIG). Analisis dilakukan berdasarkan tujuh parameter utama hidrogeologi, yaitu kedalaman muka air tanah (D), imbuhan air (R), jenis akuifer (A), jenis tanah (S), topografi kemiringan lereng (T), pengaruh zona tak jenuh (I), dan konduktivitas hidraulik (C). Hasil analisis menghasilkan peta kerentanan yang mengelompokkan wilayah studi ke dalam empat kategori, yakni sangat rendah (0-2), rendah (3-5), sedang (6-8), dan tinggi (9-10). Wilayah dengan tingkat kerentanan tinggi berada di bagian utara Jakarta seperti Kabupaten Tangerang, Jakarta Utara, dan sebagian Kota Bekasi, yang ditandai oleh kedalaman air tanah yang dangkal (hingga 0,15 meter) dan tingkat imbuhan air tanah yang tinggi (hingga 2.000 mm/tahun). Sementara itu, wilayah dengan tingkat kerentanan rendah terletak di Jakarta pusat dan di bagian selatan Jakarta seperti Jakarta Selatan, Depok, dan Tangerang Selatan, yang memiliki kedalaman air tanah lebih dari 30-meter serta tanah dengan porositas rendah. Temuan ini memberi gambaran akan perlunya pengelolaan air tanah yang baik, terutama di wilayah dengan laju urbanisasi yang tinggi. Studi ini diharapkan dapat menjadi dasar mitigasi kerentanan pencemaran di wilayah berisiko tinggi, khususnya untuk perencanaan tata ruang kota

Abstract

The high burden of final waste management causes pollution due to the low contribution of prevention at the source. The composition of Indonesia's food waste reaches 40.62%. Proper food waste management has become a challenge because the habit of segregation at the household level is still low. Home-composting is an option for management from sources with technology that is easy to operate, but its use still needs to be improved. This study looks at the factors influencing people's behaviour in composting-based household food waste management. The objective of this study is to analyze the variables of attitudes, subjective norms, and behavioural control, which affect behaviour in home-composting activities, using the theory of planned behaviour model. A quantitative approache with multiple regression analysis was used in the study. Subjective norms and behavioural control significantly (p < 0.05) influence home-composting behaviour, while attitudes (p > 0.05) do not influence home-composting.

Abstract

At present, disposable masks have become a necessity and habit for the general public. This causes an increase in the volume of single-use mask waste generation. If disposable mask waste is not managed properly and correctly it can harm living things such as fauna and contains micro plastics which have the potential to be a source of pollution in the environment. This study aims to analyze the potential impact of household-scale disposable mask waste pollution in Cinere District. The method used in this research is statistics and literature study. The results showed that the average use of disposable face masks in Cinere District was 2 pieces/day with a weight of 3.54 grams and it was estimated that the people of Cinere District produced 76,494 disposable masks waste/day with an extrapolation of the potential impact of micro plastic pollution reaching 67.31 billion/day which will be released into the environment. This will be a heavy burden on the environment, therefore good cooperation is needed between the community and the government in managing disposable mask waste on a household scale in order to reduce and prevent pollution of disposable mask waste in the environment.

Abstract

Geoparks are developed areas for sustainable development, both from social, economic, and environmental aspects. The Ciletuh-Palabuhanratu Geopark, Sukabumi Regency, West Java Province, which has been recognized as a UNESCO Global Geopark, is believed to be able to contribute to building the local community's economy with the geotourism activities it offers. It is hoped that improving the local economy will help improve the quality and welfare of people's lives. It will accelerate the achievement of SDGs targets in the pillars of economic development, especially SDGs 8. This research aims to analyze the role and effectiveness of the Ciletuh-Palabuhanratu Geopark as an agent for accelerating the achievement of SDG 8. The method used is a combined method, statistical descriptive and qualitative with structured interviews with business actors and tourism community members. The research results show that three indicators have been achieved: increasing the number of tourists, workers, and industrial linkages, but sub-indicators in industrial linkages, namely restaurants and travel services, have yet to be maximized. In general, the Geopark has been proven to function as a means of contributing to the achievement of SDG 8. Still, it requires particular strategies to increase growth in economic sub-indicators to achieve the SDG 8.

Abstract

Bogor City has 25 Puskesmas with each medical waste generation can be up around 100kg/month. The temporary storage activity requires proper treatment and management complying with regulation Ministry of Health No.56 (2015) and Ministry of Environmental and Forestry No.6 (2021). The study aims to analyze basic problem of medical waste temporary storage activity of Puskesmas in Bogor City. Qualitative approach with observation and depth-interview had been done with related parties. Analytical Hierarchy Process (AHP) is done to analyze most interested mitigation. Result shows that remaining from total population: 36% needs to provide proper medical waste temporary storage, 24% waste cold storage, 36% wastewater treatment plant (WWTP). Main obstacles found includes limited land, procedural weaknesses, and internalization of other costs. AHP is done to overcome the weakness of limited land, with three alternatives (providing additional space in the current location; providing communal hazardous waste temporary storage; providing licensed offtaker). The scoring result sequentially 14.8%, 16.3%, and 68.9%. Basically medical waste management by Puskesmas in Bogor City is in continous improvement in order to comply with the regulations. More attention need to be put on WWTP to avoid pollution especially to groundwater quality which none attention had been made so far.
