Abstract

The palm oil industry has a significant impact on the regional and national economy, generating employment, especially for farmers. Crude palm oil (CPO) can be processed into edible oil, cosmetics, and biofuels, making it a strategic commodity in global trade. However, this industry also produces abundant solid and liquid waste, such as shells, fibers, and empty fruit bunches. Factory waste must be managed and processed to prevent environmental pollution. Poor waste management can lead to various environmental problems, necessitating effective and sustainable management strategies. This type of solid waste has the potential to be used as an alternative energy source and raw material for value-added products. The objective was to determine the utilization of palm oil solid waste and its percentage, as an effort to optimize industrial waste management. The methods used included direct observation of the processing and utilization of solid waste at the factory, collection of production data, and a review of relevant literature. The results showed that empty fruit bunches are used as compost and mulch in plantations, shells are used as boiler fuel to generate steam energy, and fiber is used as supplementary fuel. According to the literature review, this solid waste still has potential for further development, such as the production of briquettes, pellets, and biomass-based activated carbon. Optimizing the utilization of palm oil solid waste can increase the energy efficiency of factories and reduce the volume of waste.

Abstract

The Tri Hita Karana philosophy encompasses the relationship between humans and God (parhyangan), between humans (pawongan), and between humans and the environment (palemahan). The study aims to determine the application of Tri Hita Karana in the management of customary forests in Demulih Village. Information was obtained through interviews with customary forest managers and direct observation. The implementation of Tri Hita Karana in the parhyangan aspect is reflected in the piodalan activities held by the Demulih customary forest management community in eleven temples within the customary forest area and there are pools for melukat activities that are open to the entire community accompanied by customary forest managers. In the pawongan aspect, the determination of customary forests is managed by the Demulih Customary Law Community (Customary Village) as the guardian of customary forests, the utilization of customary forests with production functions and the management of customary forests are regulated in awig-awig, including the prohibition of entering forest areas during the mourning period which lasts for 12 days. The Palemahan aspect is reflected in the activities of Customary Forest Stakeholders in managing Customary Forests, utilizing traditional knowledge in the utilization of genetic resources, non-timber forest products, and environmental services, as well as protecting against forest and land fires. Therefore, this research is expected to provide a source of information regarding the implementation of Tri Hita Karana in customary forest areas in Bali.

Abstract

Mangrove ecosystems play an important role in maintaining ecological balance and supporting the socio-economic life of communities. This study aims to identify the biodiversity of mangrove fauna and its role as a bioindicator of ecosystem health on the coast of Santen Island, Banyuwangi, using a descriptive qualitative approach through field observations, interviews, and documentation. The results of the study show that there are six main types of fauna found at the study site, namely mangrove crabs, Cere fish, Tembakul fish, shrimp, kijing shellfish, and brackish water crabs, as well as a mangrove ecosystem dominated by the Rhizophora mucronata species. The presence of these fauna indicates that the condition of the mangrove ecosystem is still relatively healthy. Environmental factors such as mud thickness, salinity levels, and mangrove vegetation density have a significant effect on fauna diversity. In addition, human activities such as tourism and domestic waste disposal have the potential to reduce the quality of the ecosystem. Overall, the results of this study confirm that mangrove fauna can be used as effective bioindicators to assess the ecological conditions of coastal areas. Therefore, community-based conservation efforts and the application of sustainable ecotourism concepts are needed to maintain ecological, economic, and social balance in the coastal area of Santen Island, Banyuwangi.

Abstract

Sustainable waste management has become a highly strategic issue in Gianyar Regency, Bali, in line with the increasing volume of waste generation and the limited capacity of final disposal sites. This study aims to analyze the existing conditions and performance of waste management at the Temesi landfill based on technical, environmental, economic, and social aspects. The method employed is a descriptive-quantitative approach, involving field observations, interviews with site managers, documentation of operational data from January to May 2025, and mass balance analysis. The results indicate that the total waste generation reached 30,964 tons, with an average of 213.54 tons per day, predominantly composed of organic waste. Approximately 50.16% of the waste is processed into compost, 11.08% is recycled, and 38.76% remains as residual waste disposed of in the landfill. The material recovery rate has reached 61%, indicating that the system is moving toward the implementation of circular economy principles. Economically, the waste bank operation generates a surplus of IDR 149,933,210. However, environmental aspects remain a major challenge, particularly due to the suboptimal leachate treatment system, which poses a potential risk of environmental pollution. Furthermore, improvements in technological capacity and community participation are required to support more sustainable waste management.

Abstract

This study is motivated by the high concentration of nutrients, particularly ammonium (NH₄⁺) and phosphate (PO₄³⁻), in domestic wastewater, which can lead to eutrophication if not properly treated. The objective of this research is to analyze the hydraulic characteristics and filtration performance of biochar media in a two-compartment filtration system for domestic wastewater treatment. The study was conducted experimentally using a laboratory-scale filtration unit with effective dimensions of 200 mm × 200 mm and a media height of 700 mm. The system was operated under continuous flow conditions at a discharge rate of 50 L/h for 3 hours per day. The analyzed parameters included filtration effectiveness duration, bed volume (BV), head loss, permeability coefficient (K), and hydraulic retention time (HRT), as well as the removal efficiency of ammonium and phosphate, measured using spectrophotometric methods. The results showed that the filtration effectiveness duration reached 28.17 hours, with a total treated water volume of 1.4083 m³, equivalent to 66.45 BV. The head loss value of 0.50 m remained relatively stable throughout the operation, indicating no significant clogging of the media. The permeability coefficient of 3.12 × 10⁻⁴ m/s indicates moderate to high permeability, with an HRT ranging from 21 to 25 minutes. The biochar media achieved ammonium removal efficiencies of 65–75% and significantly reduced phosphate concentrations, with the highest efficiency observed at the initial stage before declining due to media saturation.

Abstract

The increasing concentration of ammonium (NH4+) in domestic wastewater contributes to eutrophication, depletion of dissolved oxygen, and disruption of aquatic ecosystem balance. Continuous treatment systems often face operational stability challenges due to fluctuations in flow rate and pollutant loading, thereby requiring filtration technologies that are both effective and hydraulically stable. This study aimed to analyze the filtration characteristics and ammonium adsorption efficiency of an upflow Mg2+-activated biochar filter system arranged in four serial compartments. Wood-based biochar was chemically modified using a 4.2 g/L MgCl2.6H2O solution for 70 minutes. The system was operated continuously for six days at a constant flow rate of 100 mL/min using domestic wastewater with ammonium concentrations ranging from 27.74 to 42.73 mg/L. The results showed a head loss of 0.0267 m per compartment and a total of 0.1068 m, indicating stable hydraulic conditions without significant clogging. The average hydraulic retention time (HRT) was 1.79 hours per compartment (9.78 hours total), providing adequate contact time for adsorption. Ammonium adsorption efficiency reached 94.28–96.53% and increased progressively across the compartments. It can be concluded that the Mg2+-activated biochar filter system demonstrated favorable hydraulic performance and high ammonium adsorption efficiency under continuous operation.
