Abstract

Laundry wastewater contains high levels of Chemical Oxygen Demand (COD) and phosphate (PO₄), contributing to water pollution and eutrophication. This study investigates an integrated treatment approach using poly-aluminum chloride (PAC) coagulation and activated carbon adsorption to improve wastewater treatment efficiency. The research aims to determine the optimal PAC dosage (10% and 15%) and stirring time (0, 5, 15, 30, and 45 minutes) for maximizing COD and PO₄ removal. A batch reactor system was used to conduct the treatment process, and the analysis followed the Indonesian National Standard (SNI) methods. The results demonstrated that the highest removal efficiencies were achieved with a 15% PAC dosage and a stirring time of 45 minutes. Under these conditions, COD levels were reduced from 2189.62 mg/L to 143.47 mg/L, achieving a 93% reduction. Similarly, PO₄ levels decreased from 94.33 mg/L to 5.18 mg/L, corresponding to a 96% removal rate. These findings indicate that the combination of PAC coagulation and activated carbon adsorption is a highly effective treatment method for reducing pollution in laundry wastewater. This hybrid approach meets environmental discharge standards and presents a sustainable solution for large-scale wastewater treatment applications.

Abstract

Communities around the world are becoming more concerned about the environmental impact of using and heavily relying on fossil fuels, leading to a growing popularity of sustainable energy solutions. Biomass energy has become a popular topic of study around the world due to its sustainability. This study aims to investigate the feasibility of biomass waste valorization through its thermochemical or biochemical conversion into a sustainable, high-value energy commodity, thereby augmenting its economic and environmental value proposition. Hydrothermal liquefaction (HTL) was identified as the most effective method for treating biomass waste. Experiments were carried out by mixing water and biomass waste in a 500 mL autoclave batch reactor at temperatures ranging from 270 °C to 330 °C, with b/w ratios of 1:20, 2:20, and 3:20 and a retention time of 30 minutes. This study was additionally carried out under a starting pressure of 5 bar. Bio-oil had the highest product dispersion (84% at 330°C and a b/w ratio of 3:30). Meanwhile, the biochar yield was less than 10%. The solid product, on the other hand, had GCV values that were about the same as bituminous and sub-bituminous coals, at 6474 and 4888 cal/g, respectively. The carbon content of biochar at 270°C and 330°C is 50.86% and 66.77%, respectively, resulting from a variable b/w ratio of 2:20. GC-MS analyzed the highest-yielding product, bio-oil. The GC-MS study revealed a number of value-added chemicals resulting from the breakdown of hemicellulose, cellulose, and lignin compounds.

Abstract

Granulation is a critical process in quality of urea fertilizer, particularly their size distribution, significantly affects the product's performance and marketability. Urea synthesis begins with the reaction between ammonia and carbon dioxide, where ammonium carbamate is decomposed to produce urea by granulation process. This research aims evaluate the performance of granulator on urea granule size product quality based on material balance and recycle seed ratio (RSR). The granulator performance in the urea granulation process was evaluated for a production capacity of 3,500 tons/day. The methodology involves data collection from operational records in six days respectively, followed by mass balance analysis and product quality evaluation based on particle size distribution. The analysis revealed a significant deviation between design and actual data. Specifically, the design mass balance indicated a total inlet of 236,726 kg/h and a total outlet of 230,575 kg/h, resulting in a mass deficit of 6,151 kg/h attributed to dust formation and water evaporation. The measured on-size product yield was approximately 98.50% at the outlet, with the desired particle size range of 2–4.75 mm. These findings provide critical insights for process optimization and resource management in urea granulation, emphasizing the need for precise operational control to minimize material losses and ensure product quality compliance with specifications.

Abstract

With the depletion of mineral resources in Indonesia, the need for effective renewable energy alternatives has become critical. Solar energy, harnessed through photovoltaic panels, presents significant potential. However, the widespread adoption of solar panels remains limited due to their large land area requirements and susceptibility to damage. Floating solar panels, installed on water surfaces, offer a promising solution by enhancing energy efficiency through natural cooling while addressing land constraints. This study aims to analyze the motion dynamics of floating solar panels in Semangka Bay and identify the most effective design for open water conditions. Three models were tested: rectangular, kite-shaped, and perforated, using 3D simulation software. The analysis focused on the Response Amplitude Operator (RAO) under regular wave conditions at a 180° angle. The results revealed that Model 3, with 8 mooring points, exhibited the best performance in mitigating rolling, pitching, and heaving motions. The maximum rolling value reached 826.24 cm at 81 seconds, with a minimum of -735.36 cm at 86.7 seconds. Pitching peaked at 390.30 cm at 61.4 seconds and fell to -376.42 cm at 63.9 seconds. Heaving values ranged from a maximum of 17.64 cm at 62.8 seconds to a minimum of -220.94 cm at 83 seconds. This study concludes that Model 3 with 8 moorings offers superior stability, making it the optimal design for floating solar panels in open waters like Semangka Bay. By addressing environmental and implementation challenges, this research contributes significantly to advancing floating solar energy technology in Indonesia. The findings highlight the potential of efficient and resilient designs to harness Indonesia’s abundant solar energy resources effectively.

Abstract

Indonesia shares borders with Papua New Guinea, Malaysia, and Timor Leste, where border markers often face displacement or disputes due to challenging and inaccessible terrain. This research develops a waypoint navigation system on a quadcopter, integrating computer vision to enhance the detection and monitoring of border markers. The system leverages the Robot Operating System (ROS) as middleware for seamless integration and control, while a camera detects ArUco markers placed on boundary markers. Image processing, implemented using OpenCV integrated with ROS, facilitates efficient data conversion. The quadcopter autonomously navigates to target coordinates based on marker detection, with an average percentage error of 3.3% for the X-axis and 2.5% for the Y-axis. Tests showed the system could detect a 40x40 cm marker from a height of 5 meters up to a distance of 14 meters, with an average position error of 3.75%. The communication range was effective up to 150 meters before timing out. Despite the computational limitations of the Raspberry Pi hardware, the system demonstrated efficiency, scalability, and ease of deployment. Future research will focus on hardware enhancements, the exploration of advanced image processing methodologies, improved camera resolutions, and the extension of communication networks to support deployment in national boundary monitoring operations.

Abstract

Indonesia as the largest archipelago with abundant potential fishery resources contributes to national foreign exchange (Damayanti & Sugiarto, 2022).  One of the main commodities of fishery products commonly exported by Indonesia is shrimp (Dewi et al., 2022).  Increasing shrimp production through intensive aquaculture faces the challenge of disease, especially Vibrio sp. bacterial infection.  The use of antibiotics as a general solution raises resistance problems, so alternatives such as probiotics are needed.  Lactic acid bacteria (LAB) are potential candidates for probiotics because of their ability to produce organic acids that inhibit the growth of pathogenic bacteria.  This study aims to analyse the characteristics of LAB from Sidoarjo shrimp petis, a typical fermented product that has potential as a source of LAB, and test its antibacterial ability against Vibrio sp. The stages carried out in the study consisted of 5 stages including the first stage of sampling, the second stage of lactic acid bacteria isolation, the third stage of characterisation of lactic acid bacteria isolates, the fourth stage of lactic acid bacteria antibacterial test, and the fifth stage of data analysis.  The results showed the total colonies of Lactic Acid Bacteria (LAB) in the six isolates with a value of 7.08 x 106 colonies.mL. LAB characteristics on the six isolates consisted of macroscopic, microscopic, and biochemical characteristics.  Microscopic characteristics of the six isolates showed the same results, namely round, white colour, flat and convex elevation, and smooth edges.  Microscopic characteristics of the six isolates showed the same results, namely bacillus and gram-positive cell forms.  Biochemical characteristics on the six isolates showed different results.  Antibacterial tests were carried out after knowing the type of lactic acid bacteria isolates through several characteristic tests, it can be seen that there are 4 isolates including isolates PTS.5.1, PTS.5.2, PTS.6.1, and PTS. 6. 6. The results of antibacterial tests on 4 isolates have antibacterial compounds in inhibiting the growth of gram negative bacteria (Vibrio sp,).  Seen the results obtained isolates that have the greatest antibacterial activity is PTS.5.1 with a final result of 10.2625 mm.

Abstract

The marine ecosystem is vital for sustaining life on Earth, yet its vastness and complexity present significant challenges for effective monitoring and management. Integrated Marine Observing Systems (IMOS) have emerged as essential tools for understanding and protecting marine environments. This study aims to systematically review the integration of artificial intelligence (AI) into IMOS, focusing on its contributions to data processing, biodiversity monitoring, and environmental change analysis. A systematic literature review (SLR) method is employed to analyze existing research and identify key AI techniques and their applications in marine and oceanographic studies. Results indicate that deep learning is the most widely used AI method, with marine research being the primary application domain. Other areas, such as environmental monitoring and industrial systems, also demonstrate considerable potential. However, data inconsistency, operational limitations, and the lack of standardized frameworks remain significant barriers. This review highlights the transformative role of AI in enhancing IMOS capabilities and provides recommendations for addressing existing challenges to support sustainable marine management.

Abstract

Makassar City in South Sulawesi (Indonesia) is located at a low elevation of about 0-25 meters, while the coastal area is only 1-5 meters above sea level and is composed of alluvial deposits. The western boundary is directly adjacent to the Makassar Strait. These conditions make Makassar City highly vulnerable to the impacts of ocean dynamics and coastline changes caused by erosion or sedimentation, posing significant threats to infrastructure and livelihoods. This study aims to quantify sea-level changes that potentially cause coastal disasters in Makassar by detecting temporal variations in sea surface temperature (SST) and coastline changes. This study utilized remote sensing technology from AQUA MODIS, Landsat 7 ETM+, and Landsat 8 OLI/TIRS. The in-situ sea temperature measurements were conducted using a conductivity-temperature-depth (CTD) hydrographic device. In addition, the coastline verification was performed using a traverse of a global positioning system (GPS) device. Image processing was done using the SST extraction and band ratio methods to detect sea surface temperatures and coastlines, respectively. According to the AQUA MODIS data,  the maximum SST increased from 28.84°C to 30.69°C from 2004 to 2024 with the highest temperature occured in 2024. The increase of SST agreed to the increase of sea level and coastlines. The evidence of the coastline changes presented by sedimentation and erosion is about 3.47 hectares and 32.89 hectares, respectively. The geological factors that play a role in coastal sedimentation and erosion originate from river sedimentation supply and increased sea level.

Abstract

Mangrove ecosystems are important in carbon sequestration and climate regulation and contribute to climate change mitigation. However, carbon stock estimation is still mostly done manually, which is less efficient. This study utilizes remote sensing to investigate the correlation between mangrove carbon stocks and climate variability in West Java from 2019 to 2023. Mangrove land cover classification was performed using the Random Forest algorithm with NDVI and NDWI indices, while the relationship between carbon stock and climate factors was analyzed using linear regression. The results showed that increased precipitation was associated with higher carbon stocks (R2=0.5514), while carbon stocks had a negative correlation with 2-meter temperature (R2=0.8242) and sea surface temperature (SST) (R2=0.7111). This study enhances our understanding of mangrove-climate interactions and provides valuable insights for developing remote sensing-based climate resilience and coastal ecosystem management policies.
