The management of organic waste, such as food scraps and straw, remains a challenge, particularly in residential areas that produce large amounts of waste but lack effective waste management systems. This study aimed to design and evaluate the performance of two types of aerobic composters: a conventional method and a modified method using a passive aeration system with perforated pipes. Six compost material variations were tested based on different ratios of food waste to straw and observed over an eight-week period using key parameters such as temperature, height, pH, moisture content, organic carbon, nitrogen content, and C/N ratio. The results showed that All compost variations met the compost quality standards of SNI 7763:2024. No significant difference was found between the conventional and modified methods based on ANOVA test results for the C/N ratio and pH. This study concluded that variation B6 was the most favorable, as it produced a C/N ratio closest to the standard value, met the quality standard criteria during the composting process, and reached acceptable pH and carbon levels more quickly than the other variations. Therefore, the compost quality of variation A2 and A3 was superior and reached maturity in a shorter time compared to the other treatments.

A roadway is an important infrastructure for the smooth flow of the economy. High traffic volume and frequent use decrease the quality of the road and affect traffic comfort. It is important to maintain roads regularly, effectively, and efficiently. The PCI and SDI methods are effective ways to evaluate road damage advantages reflecting the actual condition of the damage. This study aim to analyze the condition of the road and comparing the maintenance cost based on assessment result from this two methods. The location conducted on connecting road at Cilubang Mekar Road in the city of Bogor. The survey covered damage such as alligator cracking, edge cracking, shoulder settlement, patching, potholes, and deterioration. The PCI value was 66.92, indicating a moderate rating, and the SDI value was 35, indicating a good rating. The recommended methods for handling the severity using the City Road Maintenance System Guidelines No. 02/P/BM/2025 are P2 (paving), P5 (patching), P6 (leveling), and U3 (regrading). An overlay of 4 cm is also recommended. The estimated cost of repairing the Cilubang Mekar road is Rp 50,021,000 based on the PCI method and Rp 30,336,000 based on the SDI method. However, since patching and potholes significantly impact the road, it is sufficient to use the SDI method for repairs.

The high rainfall that occurred throughout 2024 caused the capacity of the existing sedimentation pond to be unable to accommodate it, resulting in water overflowing and flooding the mining area. This study aims to examine the existing drainage system using quantitative and qualitative research methods. Based on the 2014-2023 rainfall analysis, Log Pearson III distribution with a 5-year return period, the planned rainfall was 142.25 mm/day, Rain Intensity 23.31 mm/hour for a rainfall duration of 3.08 hours/day. The total discharge entering the main sump was 7,771 m3/day and was discharged through the sump outlet mouth, connected by a ditch to Settlingpond 8. At this research location, there were 3 trapezoidal ditches namely: Ditch I 1.78 m3/sec, Ditch II 1.85 m3/sec, Ditch III 2.2 m3/sec. The calculation results showed that the main sump and ditch could still accommodate the total incoming discharge. The capacity of Sedimentation Pond 8, with a volume of 7,025 m3, is not sufficient to accommodate the total inflow of 8,293 m3/second and a sedimentation rate of 40-50%. Considering that the research area cannot be expanded due to land limitations, it is necessary to increase the height by 5 meters in the three settling pond compartments to enhance sedimentation efficiency. In addition, it is necessary to add 1 Ebara 200 x 150 FS4NA pump in the last compartment to help discharge water with a total discharge of 8,293 m3/day. The benefit of this research is that it is able to provide recommendations for managing the mine drainage system.

The Duta Berlian intersection near IPB University, Dramaga, Bogor experiences severe traffic congestion due to traffic volumes exceeding its capacity, high roadside friction, and the absence of traffic light. This study aims to evaluate the performance of the existing intersection and assess several improvement scenarios to improve intersection’s capacity and level of service (LOS). Traffic volume surveys were carried out using the Classified Turning Movement Counting (CTMC) method during morning and evening peak hours, followed by analysis of capacity, degree of saturation (DS), delay, and queue probability calculations. The 2023 Indonesian Highway Capacity Manual (PKJI 2023) and Ministry of Transportation Regulation No. 96/2015 were used as the analysis method and LOS classification. The analysis showed that the existing condition has DS of 1.08, average delay of 23.3 sec/PCU, queue probability of 93.23%, and LOS C. Four scenarios were tested: approach widening, conversion to a signalized intersection, application of a four-phase signal with right-turn separation, and addition of a left turn on red (LTOR) lane. The optimal scenario combined a minimum widening of 2 m with a four-phase signal and LTOR, reducing DS to 0.70, delay to 12–15 sec/PCU (LOS B), and potentially decreasing accident rates by 20–50%. In conclusion, conversion to a signalized intersection with geometric redesign and traffic flow management significantly improves intersection performance and is recommended to be equipped with yellow box junctions, markings, and signage as a medium-term solution. For a long-term solution, a grade-separated intersection is recommended.

Tugu Air Bangis Beach, located in West Pasaman Regency, has experienced severe coastal erosion caused by wave energy from the Indian Ocean. This condition has resulted in the collapse of several structures along the shoreline and threatens the remaining coastal infrastructure. Mitigation measures are therefore required to maintain shoreline stability and prevent further damage. This study aims to design the layout of coastal protection structures for Tugu Air Bangis Beach using numerical simulations to reduce the impact of wave- and current-induced erosion. The data used in this study include satellite imagery, wind data, tidal elevation data, Digital Elevation Model (DEM) data, and aerial photographs. Tidal flooding (rob) occurred in Padang City and Air Bangis from December 3 to 5, 2021, and the tidal elevation data used for the simulation were obtained from real-time measurements recorded at the Teluk Bayur Station, Padang, between December 1 and 9, 2021. Numerical simulations were performed using the CMS-Wave and CMS-Flow modules in the Surface Water Modelling System (SMS) version 10.1. The simulations were conducted in two stages. The first stage employed the existing structure layout, simulated for 216 hours of model time (equivalent to 36 hours of computer running time). The results indicated that the incoming waves approach the shoreline perpendicularly, suggesting that a breakwater is the most appropriate coastal protection structure. In the second stage, two breakwaters of equal length (200 meters each) and equal distance from the original shoreline (100 meters) were added. The numerical model results showed that this configuration effectively mitigates erosion, as indicated by sediment accumulation along several shoreline segments and the initial formation of a tombolo behind the breakwaters.

Dramaga Subdistrict, Bogor Regency, is the only area in West Java with a Monsoon-1 zone of the Year-Round Rainfall (YRR) type with rainfall exceeding 150 mm/month. The combination of duration and high intensity is an important factor that affects peak discharge/flooding, which in turn determines the dimensions of drainage channels. This study aims to analyze the duration of rainfall in Dramaga - Bogor and other characteristics. The analysis was conducted based on data from the Automatic Agroclimate Weather Station (AAWS) for 2018-2024 at the Bogor Climatology Station. It was found that the duration of heavy and very heavy rainfall in Dramaga was mostly 2 hours. In addition, the highest monthly rainfall in Dramaga occurred in November (419.63 mm/month), while the lowest was in June (107.36 mm/month). Most of the rainfall occurred between 13:00 and 18:00 WIB, with the peak rainfall between 16:00 and 19:00 WIB.

Rapid high-rise construction, especially in seismically active Java and Yogyakarta, demands lateral stiffness consistent with SDG 9 and SNI 1726:2019 to ensure resilience against earthquake actions. Shear walls and steel bracing are widely used to control interstory drift and stability, yet comparative evidence tailored to Yogyakarta remains limited. Methods used by using a finite-element model of a 21-story apartment and perform elastic response-spectrum analyses based on SNI 1726:2019. Four lateral systems are compared, emphasizing concentric X-bracing (CBF-X) and eccentric K-bracing (EBF-K). Performance metrics include interstory drift, P-Δ stability coefficients, and horizontal and vertical irregularities. Models incorporate rigid diaphragm assumptions, gravity and lateral load combinations, and cracked-section modifiers for shear walls consistent with code recommendations. Member forces were also checked. The results indicate that all structural configurations satisfy the standard requirements of SNI 1726-2019. The smallest interstory drift occurs in the structure with the K-bracing system, with minimum values in the X direction ranging from 3.992 mm and maximum 19.395 mm, and in the Y direction minimum from 1.172 mm and maximum 36.344 mm. The P–Delta effect shows the smallest stability coefficients in the K-bracing system, with X-direction minimum values of 0.0019 mm and maximum 0.0256 mm, and Y-direction minimum values of 0.0018 mm and maximum 0.0104 mm. Analysis of structural irregularities using X-ray diffraction yields superior results compared to other structures. For a tall building in Yogyakarta’s seismic setting, combining shear walls with steel bracing is effective and code-compliant. Among the examined schemes, EBF-K minimizes drift and P-Δ effects, offering superior lateral stiffness and energy dissipation, whereas CBF-X excels in meeting irregularity criteria and maintaining global stability. The results provide location-specific guidance for selecting lateral systems in Indonesian high-rise design and support performance-oriented detailing under SNI 1726:2019

Indoor thermal comfort in tropical urban houses is important to manage because it determines the quality of life for the inhabitants. However, it is prone to sudden changes of temperature, especially in a developing country, such as Indonesia, where indoor air circulation is mainly supported by windows. This research aims to evaluate the indoor thermal comfort in Indonesian urban houses, and to analyse the correlation of outdoor temperature and the number of windows on the indoor temperature. This study took place in the Greater Bogor Area with a total of five houses. Outdoor and indoor temperatures were monitored in four areas for each home, which are the living room, bedroom, toilet, and terrace. The dry and wet temperatures were analysed to determine the indoor thermal comfort status based on ASHRAE (The American Society of Heating, Refrigerating, and Air Conditioning Engineers)-55. The correlation between outdoor temperature and the number of windows on indoor thermal comfort was analysed using multiple linear regression. Three of the five houses had areas that met the standard for thermal comfort. The areas were mainly the terrace and the bedroom. The average (standard deviation) of outdoor dry and wet temperatures was 27.79 oC (1.03 oC), and 25.59 oC (1.56 oC), respectively. While for the indoors, the average for dry and wet temperatures were 27.96 oC (1.87 oC), and 25.39 oC (2.31 oC). Outdoor temperature and number of windows showed insignificant correlation with indoor temperature (R2: 0.1448; adj R2: 0.08145; p>0.121), opposing the previous studies on the effect of outdoor temperature and number of windows on indoor temperature. Apart from this finding, the effect of windows/ventilation's presence on indoor thermal comfort cannot be undermined. As ventilation serves as a part of human adaptation to heat, it is becoming more important amidst the increased extreme heat caused by climate change.
