Abstract

The streaming current monitor (SCM) is an instrument used to measure small particles suspended in water and ensure their stability. It can be operated in real time to detect changes in water quality and temperature. The SCM provides a continuous flow that can quickly and accurately measure changes in water quality. In the Water Treatment Plant (WTP), it supplements conventional laboratory tests, enabling longer testing times and reducing the cost of chemical materials. The SCM also provides real-time data analysis which is logged in the Supervisory Control and Data Acquisition (SCADA) system. Integrating this technology reduces the need for manual decision-making and minimises human error, offering flexibility and control to operators. SCM technology was developed at IPA Sadu in Soreang to improve operational efficiency. It also uses other real-time monitoring instruments, such as those measuring pH, turbidity and chloride. These instruments are integrated into the SCADA data management system, enabling data collection and monitoring of potential issues and enhancing the efficiency and accuracy of the water quality control process.

Abstract

One of the ecological roles of mangroves is to act as a barrier to seawater intrusion, which is crucial for maintaining the balance of coastal ecosystems. Gebang Village is a coastal area with mangrove forests along its coastline, but the density of these forests varies from location to location. This study aims to determine the relationship between mangrove forest density and the quality of well water in Gebang Village, the main source of clean water for the local community. Well water samples were taken at three locations selected using a purposive sampling technique based on mangrove density levels (low, medium and high) to ensure comprehensive representation. The results showed a significant relationship between mangrove density and salinity, turbidity and total dissolved solids (TDS) in the well water of Gebang Village residents, particularly in wells close to the coastline. The higher the mangrove density, the lower the salinity, turbidity and TDS parameter values in well water, indicating the effectiveness of mangroves in filtering and protecting groundwater sources from seawater contamination.

Abstract

Climate change is a phenomenon caused by human activities that increase greenhouse gas emissions, particularly carbon dioxide (CO₂), thereby accelerating global warming. In Surabaya City, the Surabaya River serves as a primary raw water source for the local water utility (PDAM). However, land-use changes in the riparian zone—from Green Open Spaces (RTH) to residential and industrial areas—have reduced environmental carrying and buffering capacities due to rising CO₂ emissions. This study aims to analyze the CO₂ absorption capacity of RTH in the riparian zone of the Surabaya River, specifically in the Sepanjang – Gunungsari segment. The methods used include literature review, collection of primary and secondary data, and analysis of RTH suitability based on applicable regulations. The calculation of CO₂ absorption capacity considered the area of existing RTH and the types of vegetation present. The results show that the existing RTH area is only 63,000 m², significantly below the ideal requirement of 124,857 m². With the current vegetation composition, the total CO₂ absorption capacity is estimated at 594,628.69 kg CO₂ per year. These findings highlight the importance of maintaining and expanding RTH in riparian areas to support climate change mitigation in urban environments.

Abstract

Galaxy II Street, located in the Jekan Raya District, was chosen as the study site due to its representative condition regarding road infrastructure issues in Palangka Raya City, particularly its damaged pavement. This study utilized two types of data: primary data and secondary data. The road damage assessment was conducted using the Pavement Condition Index (PCI) method based on ASTM D6433-07 standards, while vehicle speed analysis was carried out using the spot speed method. The results showed that Galaxy II Street had an average PCI value of 37, which is categorized as very poor. The analysis of vehicle speed indicated a negative correlation between the level of road damage and vehicle speed. The lower the PCI value, the lower the recorded vehicle speed. These findings are consistent with previous studies, which state that pavement condition has a significant influence on driving behavior.

Abstract

The rising trend of working from anywhere has increased activity in cafeterias, which produce wastewater with high levels of organic matter and suspended solids. If discharged without treatment, this wastewater can pollute the environment and disrupt ecosystem balance. This study aims to evaluate the effectiveness of plant quantity and retention time in a constructed wetland system of the sub-surface flow type, using the emergent macrophyte wetland method with amazon sword plant (Echinodorus palaefolius) plants to reduce Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS) in cafeteria wastewater. Variations in plant quantity (12, 14, and 16 stems) were tested over a 16-day retention period. The results showed BOD removal efficiency ranging from 94.62% to 97.85%, while TSS reduction ranged from 73.3% to 97.8%, depending on the sampling time. In the best-case scenario (on day 4), the system reduced BOD from 185.9 mg/L to 6 mg/L and TSS from 150 mg/L to 3 mg/L, meeting the effluent quality standards for restaurant wastewater. This high efficiency is attributed to physical filtration through roots and substrate, as well as rhizospheric microbial activity supported by the roots of the Amazon sword plant (Echinodorus palaefolius).

Abstract

Indonesia's energy demand continues to increase, but energy fulfillment still relies on coal, which has a negative impact on the environment. Seeing the potential of biomass as fuel, this study is intended to analyze the potential use of soybean dregs from soy sauce factories and sugarcane bagasse as fuel and to evaluate the characteristics of biomass briquettes according to the composition and particle size of the materials. Sugarcane bagasse and soy sauce bagasse were varied with a ratio of 63%:27%, 45%:45%, and 27%:63%, respectively with a mixture of 10% adhesive from cassava flour and molasses. The mesh size was chosen at 80 (177 μm) and 150 (99 μm) to compare the effect of particles <100 μm and >100 μm. Briquettes with characteristics that meet almost all aspect standards are briquettes with a composition of 27% soy sauce dregs and 63% sugarcane dregs with a mesh size of 150. The results of the water content are 4.20%, ash content 7.46%, volatile matter content 23.73%, and calorific value 5948 calories/gram. However, the results of the CO emission test in the early minutes of combustion (1287 ppm) did not meet the quality standard. This study proves that soy sauce dregs and sugarcane dregs waste can be an  environmentally friendly alternative fuel with further emission control.

Abstract

The application of EPA SWMM 5.2 is needed to reduce flooding in Sukolilo Housing, because the housing was built by filling land so it changes the land use from a pond area to a runoff area, causing flooding. The method used in this study is a quantitative descriptive method. This study's aim is to simulate and optimize the capacity of the Sukolilo Housing drainage network using the SWMM 5.2 software program. In this study, hydrological and hydraulic simulations were carried out using SWMM 5.2 software which can represent flow and inundation spatially and temporally. Further analysis was carried out using a hydrological and hydraulic approach to calculate the planned rainfall and runoff discharge resulting from each extreme rain event. The simulation was carried out on the existing drainage network model by entering actual parameters including base elevation, channel cross-section dimensions, channel shape, and network layout with a site plan map of the area. After the latest simulation was carried out, the results were obtained, namely enlarging the secondary channel to 0.80 m × 0.80 m and reducing the tertiary channel to 0.50 m × 0.35 m, the flow capacity increased significantly without sacrificing hydraulic performance and saving material usage.

Abstract

Egg production from laying hens in Indonesia is so high that if the egg shells produced are not used properly, they will produce waste. Chicken eggshell waste has a high mineral content, one of which is calcium. Calcium can be utilized as a heterogeneous catalyst which can be used in making renewable energy such as biodiesel. Biodiesel is an alternative energy that is being widely developed because it can be an environmentally friendly alternative to diesel engine fuel. This research aims to determine biodiesel obtained from tamanu oil (Calophyllum inophyllum) by etherification and transesterification processes using a catalyst modified from egg shells using a wet impregnation method using alkaline potassium hydroxide. The catalyst used is the catalyst with the highest alkalinity for making biodiesel. The biodiesel produced had the highest yield of 76.9040% with a density value of 0.94981 gr/ml and a viscosity of 4.11412 cSt.
