Abstract

It is estimated that the amount of water needed by Universitas Diponegoro will increase in the years to come. Several efforts are required to ensure the fulfillment of water needed while also considering its sustainability. There have been studies on water conservation at the industrial level. Still, limited studies have discussed this problem in Indonesia specifically at university level. Therefore, this study discusses the water conservation program at Universitas Diponegoro that might be used as a reference for other universities to address water supply problems. This study aims to discuss in depth water conservation efforts at Universitas Diponegoro. This study incorporates a descriptive-qualitative approach along with direct observation. Some programs on water supply have been implemented in Universitas Diponegoro such as conservation, treated water consumed, water recycling and water-efficiency. The existence of rainwater harvesting tanks (RWH), reservoirs, biopores, wastewater treatment plans (WWTPs) and ponds are among the efforts that have been applied at Universitas Diponegoro in order to conserve the water. To date, Universitas Diponegoro has successfully conserved more than 75% of the water, recycling about >50% of wastewater, installing about >50% of water-saving equipment, and has treated clean water into drinking water using reverse osmosis.Keyword: water, conservation, sustainability, campus

Abstract

TPA Kebon Kongok is one of the Final Processing Sites in Indonesia that uses a sanitary landfill system. The limited availability of land and the increasing height of the waste pile that has been dumped during the TPA operation period and the discovery of leachate puddles at several points in the TPA area are problems that need to be addressed immediately so as not to disturb the environmental ecosystem and society. The purpose of this research is to determine the depth of leachate pollution in the subsurface and map the leachate distribution pattern around the TPA Kebon Kongok area. This research was conducted using the resistivity geoelectric method with a 2-D Wenner configuration in 10 lines and the Self Potential (SP) method with an area 132,732 m² and 138 data point. Based on data analysis, it is found that the layer indicated as leachate has a resistivity value of 0.143-4.71 Ωm. Based on the results of the SP analysis, it is known that the accumulated leachate streams are interpreted to have relatively lower self-potential values with anomalous values of -100 mV to -40 mV. Low potential values were found in the northwest to southeast of the study site, while relatively high potential values were found in the southern part of the study site. The direction of leachate distribution in various directions is due to the fact that the study area has different elevations and the subsurface layer is composed of layers that easily drain liquids, which are indicated as sand layers. This research is expected to be a consideration for the management of TPA Kebon Kongok in taking mitigation steps from leachate pollution.

Abstract

In the current era of the Industrial Revolution, there is a substantial increase in effluents from industrial discharges and domestic waste flowing into the sea, leading to contamination of water bodies. This includes pollutants such as heavy metals (Cu, Pb, and Zn) and microplastics, which eventually settle and contaminate sediments. Research on sediment contamination in Indonesia has been quite numerous and varied, but none has employed the scientometric method to analyze the trend of sediment contamination. Using CiteSpace, this study analyzes trends and patterns in research topics, citation frequency, and publication numbers over the past 25 years, based on co-occurrence, co-word, and co-citation analyses. The study examined 177 research articles indexed by Scopus. Findings reveal substantial international collaboration, with Indonesia leading with 167 publications, Malaysia with 19, and Japan with 15, showing a significant gap. The research spans various subject areas, including Environmental Science (111 articles), Earth and Planetary Sciences (74 articles), and Agricultural and Biological Sciences (55 articles). This study will provide a quantitative and visual overview of sediment contamination research in Indonesia, offering a comprehensive discussion of the findings.

Abstract

In order to execute sustainable agriculture, an agricultural system is required, particularly an effective and efficient irrigation system, to maximize the use of available water while minimizing water waste. For these reasons, a technological approach is required to implement more efficient irrigation and be environmentally friendly. Smart irrigation systems utilizing data-driven techniques such as the Internet of Things (IoT) that minimize the environmental footprint are one of the current technological approaches on the rise. However, studies on this topic's challenges and prospects have been conducted and still need to be completed. This study aims to provide a more thorough understanding of the use of smart irrigation so that it can be more widely adopted. Recent studies on sophisticated irrigation management principles and smart irrigation monitoring are highlighted. Researchers will be able to use this review to identify directions and gaps for upcoming research activities in this area and monitor and develop control prospects associated with irrigation agriculture.

Abstract

This review is the first attempt to integrate natural and anthropogenic drivers of coastal subsidence, the evolution of monitoring techniques, and geo-environmental impacts, with a focus on coupled human-environment systems. This review compares traditional geodetic techniques (levelling, GNSS) with other satellite and geophysical methods (InSAR, LiDAR, microgravity, and seismic survey) and assesses subsidence monitoring under different geo-environmental conditions. Empirical evidence from the northern coastline of Java, in particular Semarang, shows that subsidence has occurred at an annual rate of 2–10 + cm, which is directly linked to groundwater exploitation, alteration of land use, and coastal construction, which exacerbates tidal flooding, coastal recession, saltwater encroachment, ecosystem destruction, infrastructure deterioration, and social impacts. The findings suggest that subsidence is a unique geophysical phenomenon and not a result of anthropogenic interactions with natural systems involving water, land use, coasts, and public administration frameworks. This type of integration is essential for improved risk assessment, resilience, and sustainable development.

Abstract

This research examines the effect of certified personnel competence in industrial wastewater treatment on the fulfillment of industrial wastewater quality standards in Semarang City, Indonesia. Amid rapid industrial expansion, ensuring environmental sustainability has become increasingly challenging, prompting regulatory requirements for operator certification. The study adopts a quantitative descriptive approach, gathering data from 26 key wastewater treatment operators (POPAL) in major manufacturing sectors through structured questionnaires, interviews, and direct field observation. Findings demonstrate that the majority of industries in Semarang have already appointed certified wastewater treatment personnel, with most respondents possessing a strong educational background and extensive experience. Results indicate that certified operators significantly improve industrial compliance with wastewater quality standards, particularly regarding key parameters such as Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS). Certified personnel exhibit enhanced ability in identifying risks, operating and maintaining wastewater facilities, and implementing standard procedures, which directly translates into higher rates of regulatory compliance. However, the research also finds that certification alone is not a panacea; certain industries still face challenges due to outdated technology, insufficient management support, or a lack of continuous training. These factors may hinder optimal wastewater treatment, even when certified personnel are present. The study’s implications are twofold. Theoretically, it affirms the critical role of human resource competence in effective industrial environmental management. Practically, it encourages policymakers and industry leaders to prioritize ongoing professional development, technological upgrades, and supportive management systems, in addition to certification. Such efforts will further strengthen the effectiveness of certified operators and improve overall environmental compliance. In conclusion, certified personnel competence, when supported by proper institutional and technological resources, is a key driver for successful and sustainable industrial wastewater management in Semarang.

Abstract

The increasing population and anthropogenic activities in cities/regencies in Indonesia have caused many waste-related problems, which can trigger environmental and human health. In addition to population growth, rapid economic development has resulted in an increasing amount and type of waste. The coastal area is one area that still needs to get adequate solid waste services. There have been many studies on waste management. However, research has yet to examine the amount and composition of waste generation in coastal areas that have not been served by waste management.. This study shows the waste generation and composition trend in coastal areas that must be served in waste management and determines the appropriate waste management strategy. This research method uses a transect walk survey carried out by following a predetermined route in the area. Paths are made randomly by forming circles or straight lines for 10 km. The composition of illegal waste dumps found included leaves (69.02%), plastic (15.24%), branches and twigs (9.93%), paper and cardboard (3.75%), food waste (1.97%), and rubber (0.1%). At least 1.59 tonnes/day of illegal waste is estimated in Sidorejo Village. While this figure increases at the district level, the amount of unaccommodated waste is estimated at 19.85 tonnes/day. Efforts to handle waste that can be done are changing the mindset and paradigm of the community through an educational approach, improving the waste management system by providing waste facilities and reducing the amount of waste collected through a simple program (Reuses, Reduces, Recycle) that involves the community.

Abstract

In 2017-2019, the Tanah Laut Regency, Banjar Regency, Banjarbaru City population was relatively high and continued to increase every year. The increase in the population reaches 1.39% to 2.92%. Along with population growth, the human need for clean water also increases, especially from groundwater. The study aims to assess the vulnerability of groundwater to contamination. The method used for the analysis of groundwater vulnerability to contamination is the DRASTIC method. It refers to seven parameters, namely groundwater depth (D), net recharge (R), aquifer media (A), soil layer (S), topography (T), impact to vadose zone (I) and hydraulic conductivity (C) by using geospatial analysis to calculate the DRASTIC Index/DI. From the results of geospatial analysis, there are three zones of groundwater vulnerability to contamination based on DI values, namely low vulnerability (95-106), medium vulnerability (106-146), and high vulnerability (146-186). The distribution of high zones dominates in the research area around of 75, 8%. The DRASTIC method requires a lot of data to provide an accurate analysis of groundwater vulnerability zone maps. This method has excellent accuracy and more effective in producing a map of the groundwater vulnerability zones to contamination.
