<![CDATA[Transportation is crucial to Indonesia's development, with highways being the main element. Road damage is often caused by low-quality materials, loads, and weather. The modification of asphalt mixtures with additives can improve their stability. Porous asphalt, which is effective in terms of drainage and strength, can improve the road safety. In Tulungagung, marble waste can be used in asphalt mixtures, thereby reducing waste and cost. This study evaluates the use of marble waste in asphalt mixtures, particularly the characteristics of the porous asphalt Marshall. The method used was The Australian Asphalt Pavement Association (AAPA) Marshall with stability parameters, Flow, Voids in Mix (VIM), Voids in Mineral Aggregate (VMA), Cantabro Loss (CL), and Asphalt Flow Down (AFD), with variations in asphalt content of 4.5, 5, 5.5, and 6%. After obtaining the OAC, the test specimens were made with marble fragments and marble powder contents of 15, 25, and 35%. The results showed that the OAC was 5% with Marshall characteristics, namely stability of 1,037 kg, flow of 3.33 mm, Marshall quotient of 311 kg/mm, VIM of 24.96%, and VMA of 27.84%wasmarble frMarshallat a content of 25% Marshall characteristics are stability 509 kg, flow 3.00 mm, Marshall quotient 200 kg/mm, VIM 19.00%, and VMA 50.00%. and marble powder at 15 % content is stability 805 kg, flow 3.00 mm, Marshall quotient 279 kg/mm, VIM 27.00% and VMA 40.00%. All parameters meet the specifications except VIM, which does not meet the specifications because the addition of marble powder reduces voids in the porous asphalt. The AFD value decreases with an increasing percentage of marble fragments and marble powder, affecting the separation of asphalt in the mixture and the permeability value.]]>

<![CDATA[Irrigation systems play a crucial role in enhancing rice production. However, determining the optimal method for irrigation system optimization using conventional approaches is often challenging. This study aims to identify the optimal irrigation system represented by the water table level using a Genetic Algorithm (GA) model. The GA model was chosen for its advantages in addressing non-linear problems and finding global solutions without being trapped in local optima. The model was developed based on a laboratory-scale rice cultivation experiment involving four water table treatments: 0–7 cm with oxygen enrichment via Fine Bubble Technology (TA1), 4–7 cm (TA2), –5 to 0 cm (TA3), and 2–4 cm (TA4) above the soil surface. The research was conducted from February to June 2024 at Kinjiro Farm, Bogor City. The four treatments produced varying yields, with TA 2 achieving the highest yield of 6.86 tons/ha, followed by TA1 (5.35 tons/ha), TA3 (5.00 tons/ha), and TA4 (4.80 tons/ha). Based on these data, the GA model successfully identified the optimal water table level of 3.5 cm above the soil surface, which could increase production to 7.40 tons/ha. This water level represents a moderate irrigation depth, requiring a medium level of irrigation compared to the four tested treatments perlakuan.]]>

<![CDATA[The Citanduy Watershed is one of the largest watersheds on Java Island and is in critical condition. The Upper Citanduy Sub-watershed is the main sub-watershed in the Citanduy Watershed, which needs attention because it greatly affects the quantity and quality of its water. The Soil and Water Assessment Tool (SWAT) model, which is a hydrological model developed in the United States, can be used to predict the quantity of water. However, the water balance in the SWAT model uses the water balance for plants planted on dry land (up land) and is less suitable for watersheds that have rice fields (low land). For watersheds that have rice fields, pot hole and modified SWAT features have been tried and developed. This study aims to analyze the performance of the SWAT model with original features, pot hole features, and modified features in the QSWAT program to predict water discharge in the Upper Citanduy Sub-watershed. The results of the study indicate that the modified SWAT has the best performance compared to the original SWAT and pot-hole SWAT, as indicated by the NSE and R2 values. The NSE values of the original SWAT, pot hole SWAT, and modified SWAT were 0.70, 0.73, and 0.75, respectively. The R2 values of the modified SWAT, Original SWAT, and pot hole SWAT were 0.94, 0.93, and 0.94, respectively.]]>

<![CDATA[Educational institutions including IPB University Dramaga is generating paper and food waste. Waste paper reaching 679.84 kg per day and food waste reached 379.55 kg/ day. Both is collected at Taman Semangat located in Cikabayan IPB Dramaga and has the potential to pollute the environment if not treated further. On the other hand, IPB has the potential of cattle rumen that has not been effectively utilized. One of the waste treatments that can be done is composting. This study aims to analyze the characteristics and quality of compost, determine the best compost variation, and analyze the potential of composting in reducing paper and food waste at IPB Dramaga Campus. Composting was done by mixing waste paper and food waste using cow rumen bioactivator. Composting was carried out for 8 weeks aerobically with two composting methods, namely open windrow and aerated static pile (ASP). The results showed that compost characteristics including color, volume, temperature, moisture content, pH, C-Organic, N-Total and C/N ratio were in accordance with SNI 19-7030-2004. Compost that is in accordance with the standard is found in variations A3 and B3 in four weeks. In this variation, the weight ratio of waste paper to food waste and cow rumen is 1.75: 5: 3,25. This composting variation is able to reduce waste paper and food waste based on variations A3 and B3 by 67% and 13%.]]>

<![CDATA[Jakarta, as Indonesia’s most populous megacity, had a population of 11.14 million in 2024. Covering an area of 661 square kilometers, it is also the country’s most densely populated city, with over 16,500 individuals per square kilometer. High population density brings challenges, particularly in access to essential public services like education and healthcare, which are crucial for sustainable urban development. This study examines spatial disparities in the distribution of health and educational infrastructures in Jakarta concerning population density. Through overlay analysis, two models were developed: the Educational Facilities Gaps Map and the Health Facilities Gaps Map, categorizing areas as well-served, moderately served, or underserved. The findings highlight significant disparities across Jakarta’s administrative regions. Central Jakarta has the highest accessibility, with 57.43% of its area well-served for education and 65.06% for healthcare. Conversely, North Jakarta and Kepulauan Seribu experience the most severe service gaps, with 51.92% and 100% of their areas underserved in education, and 50.20% and 85.92% in healthcare, respectively. East, South, and West Jakarta exhibit moderate service coverage, though underserved zones remain. These results emphasize the importance of strategic urban planning to improve equitable access to public services. By incorporating geospatial analysis into policymaking, decision-makers can optimize facility distribution and infrastructure development, reducing service disparities, especially in underserved areas.]]>

<![CDATA[Population growth and increased mobility in the area surrounding IPB University, particularly along Raya Dramaga Road and the Babakan Raya intersection have led to severe congestion. This intersection serves as a critical point where vehicle accumulation frequently occurs due to crossing movements, particularly during morning and evening peak hours. The majority of vehicles involved in these crossings are motorcycles owned by IPB students heading toward the university’s main gate. Therefore, effective measures or policies are required to reduce crossing movements during peak hours, such as redirecting a portion of student traffic to alternative gates to alleviate congestion at Babakan Raya intersection. This study aims to identify traffic volume, road and intersection capacity, and the actual intersection performance, design an optimal Gate 4 for IPB, and analyze its impact on traffic performance. The research methodology includes primary and secondary data collection, intersection performance analysis, and the design of a roundabout and intersection improvements based on PKJI 2023 standards and Transportation Ministerial Regulation No. 96 of 2015. The study findings indicate that widening minor approach lanes, constructing traffic islands, and eliminating side friction increase the capacity of Babakan Raya intersection from 2,985.32 PCU/hour to 3,413.88 PCU/hour. The degree of saturation decreases from 1.22 to 0.87, and intersection delay is significantly reduced from 46 seconds/PCU to 14 seconds/PCU, improving the level of service (LoS) from category E (poor) to B (good). The construction of Gate 4 at IPB successfully redirects vehicle flow, particularly motorcycles, which previously traversed Babakan Raya intersection to access Gate 1 of IPB. With a capacity of 2,149 PCU/hour, the Gate 4 roundabout effectively accommodates high vehicle volumes during peak hours. Traffic performance analysis results demonstrate that intersection improvements and the development of Gate 4 at IPB effectively enhance traffic performance in the external area of IPB, mitigate congestion, and improve vehicular movement efficiency.]]>

<![CDATA[The Kotabaru Village in West Bekasi District, Bekasi City, frequently experiences flooding. Flood events in this area have even reached depths of 100 cm. These events disrupt residents' activities and force them to evacuate. An evaluation of the drainage channels is necessary to identify the causes of flooding and develop solutions. This study aims to analyze the causes of flooding and provide recommendations for flood management based on simulations using EPA SWMM 5.2 software. The data used in this study include daily rainfall data from the GPM (Global Precipitation Measurement) satellite for the period 2013-2022, a contour map of Bekasi City, and a land cover map. Hydrological analysis methods and modeling using EPA SWMM 5.2 are employed to identify flood points and accurately calculate the capacity of the drainage channels. The hydrological analysis results show that rainfall in this area follows a Log-Pearson Type III distribution. The design rainfall with a 5-year return period is 267.87 mm. The SWMM model involves 30 subcatchments, 126 junctions, 168 conduits, and 1 outfall. A 24-hour simulation indicates that 5 channels are highlighted in red, meaning their capacity is insufficient, and the channel profiles show overflows due to flow queuing towards the Cakung River. Capacity analysis shows that the simulated discharge under existing conditions reaches 44.01 m³/s. After improvements, the Cakung River and the residential drainage channels function properly without any overflows.]]>

<![CDATA[Anchors have been used for many years as restraint structures to maintain the stability of slopes. As the restraining effect of such slopes is exerted by the tensile force acting on the involved anchors, investigation of this tensile force is important when maintaining anchors. As multiple anchors are installed on slopes, investigation of numerous anchors is essential to determine the tensile force. This study describes the maintenance of anchors based on the residual-load results obtained using the involved SAAM (Sustainable Asset Anchor Maintenance) system, which uses a compact and lightweight SAAM jack capable of performing lift-off tests on numerous anchors.]]>
