Abstract

The increasing number of passengers and flights at Jenderal Ahmad Yani Airport Semarang is predicted to continue to increase after the Covid-19 pandemic. According to data, the increase that occurred after the pandemic increased by 57% in the period 2021-2023. This increase has the potential to affect the condition of the runway pavement. In 2018, maintenance activities on the runway that have been carried out with the Overlay and Leveling method are planned to maintain pavement conditions until 2038 or 20 years of service life. To anticipate these conditions, flight traffic forecasting is required based on existing conditions until the end of the planning service life. The forecasting results show that the number of passengers can reach 14,369,352 people, which exceeds the planning of only 5,700,000 passengers. With a significant increase in the number of passengers, the results of the evaluation of pavement conditions using the COMFAA and FAARFIELD mechanistic program approaches are represented in the CDF (Cumulative Damage Factor) value. Stating in 2038 the CDF value = 21.25 with a remaining life of 0.9 years. That way the increase that occurs causes significant damage, therefore the rehabilitation process recommended by the FAA is needed with a top layer thickness of 100mm, with implementation carried out in 2026 or when the remaining 5 years of pavement life. Keyword: CDF, Mechanistic, Forecasting, Pavement Life Remaining.

Abstract

The quality of water used in concrete mixes, especially the Total Dissolved Solids (TDS) content, is often ignored despite its significant effect on the compressive strength of concrete. Normal, sea, and swamp water have different TDS characteristics, where sea water tends to have higher TDS. This study aims to analyze the relationship between the TDS value of water and the compressive strength of concrete at 7 and 28 days and identify significant differences in the compressive strength of concrete using normal, sea, and swamp water. The method used was experimental research, with samples consisting of 3 categories of water (normal, sea, and swamp) and 3 samples per category. TDS values were measured using a TDS meter, while concrete compressive strength was tested with a digital press. The research was conducted through four stages: water sampling, concrete mix preparation, molding of test specimens, and compressive strength testing. Linear regression analysis showed that the higher the TDS value, the lower the concrete compressive strength at 7 and 28 days. In addition, the ANOVA test revealed significant differences in the compressive strength of concrete at 7 days among the three types of water. These findings indicate the importance of paying attention to water quality in concrete mixes to produce optimum quality concrete. Keyword: concrete compressive strength, sea water, swamp water, TDS.

Abstract

Road pavement design must meet roadworthiness requirements to ensure user safety and comfort. One factor is road surface roughness, because low roughness can cause slippery roads and increase the risk of accidents due to vehicle slippage. Road surface roughness testing using the British Pendulum Tester (BPT) is one of the parameters to determine the roughness value. Roadworthiness requirements also apply to asphalt modifications, such as the use of Glycelin Pitch (GP) type oleochemical waste as a substitute for 60/70 pen asphalt. Roadworthiness requirements in this modification are a series of advanced tests, where various tests conducted before paving have been carried out in previous studies and meet the 2018 Bina Marga Technical Specifications Revision 2. This study focuses on road surface roughness testing with the aim of proving that GP can be used as a substitute for penetration asphalt with a content of 27% (GP1) and 14.2% (GP2). The test results showed that the mixture with GP1 provided a higher British Pendulum Number (BPN) value of 80.70 compared to GP2 which was 72.20, while the BPN value for the AC-WC control mixture was 74.50. The average surface temperature in this test was 35.4°C for the GP2 sample and 37.5°C for the GP1 sample. Based on the recommended minimum friction resistance value reference for wet conditions, the GP1 and GP2 mixtures meet the safety requirements for various types of road locations, including locations with high friction such as roundabouts and sharp turns. Thus, the GP mixture shows good potential for application on roads that require high friction, supports traffic safety, and meets road function standards.

Abstract

Clean water is a basic necessity crucial for life, health, and socio-economic development. In Medan Deli District, although water sources are still available, challenges arise in distribution, technical losses, and processing and management capacity. This study aims to analyze the projection of clean water needs and availability in the next 10, 30, and 50 years, taking into account population growth, service coverage, and the capacity of PDAM Tirta Deli. The methods used include literature studies, secondary data collection, and calculations of domestic and non-domestic water needs based on the Directorate General of Human Settlements standards. The projection results show an increase in population from 193,196 people (2025) to 239,426 people (2075), and an increase in total water needs from 289.57 liters/second to 358.86 liters/second, including 15% technical losses. The PDAM's installed capacity of 400 liters/second is nominally sufficient, but its effectiveness may decrease without improvements to the distribution and management system. This study recommends long-term planning, infrastructure improvements, and attention to climate change and consumption patterns to ensure the sustainability of clean water supplies in the future. Key recommendations include investment in water leakage reduction technologies and strengthening the institutional capacity of water utilities (PDAMs) to improve the efficiency of the clean water supply system.

Abstract

School transportation in Sleman Regency faces various problems, including limited number of fleets, operational schedules that are not yet optimal, and the lack of adequate safety facilities. This condition means that some students are not served well and pose a risk to their safety and comfort during their trip. This research aims to evaluate the operational performance and services of school transportation, as well as formulate improvement strategies. The method used is a quantitative and qualitative approach through field surveys, interviews and distributing questionnaires. Service performance is analyzed using the Importance Performance Analysis (IPA) method, while development strategies are prepared through SWOT analysis. The research results show that at departure time, the load factor reaches up to 126.3% in corridor 1 and 118% in corridor 2, which indicates overloading with fleet availability of only 66.67%. Meanwhile, IPA analysis identified priority improvement indicators such as Emergency Response Information, Safety Equipment: glass breakers and APAR, and Safety Belts. The improvement strategy resulting in a SWOT matrix that is used in the short term includes preparing different return schedules and improving safety facilities such as providing fire extinguishers and glass breaking hammers. Long-term improvement strategies include adding corridors to school transportation services and digitizing reporting. It is hoped that this evaluation will become the basis for improving safer, more efficient and equitable school transportation services in Sleman Regency.

Abstract

The material distribution process is one of the key aspects in the success of construction projects, especially in the construction of structures such as retaining walls that require timely delivery and maintained material quality. This study aims to analyze and evaluate the material distribution monitoring system in the construction of retaining walls in the environment. The methods used include field observation, interviews with the project implementation team, and collection of logistics data and material distribution schedules. The results of the study indicate that the main challenges in the distribution system are delays in material supply due to disruption of road access and lack of coordination between project divisions. The implementation of a monitoring system based on mapping schedules and distribution points can improve the efficiency of material flow and minimize work delays. Recommendations from this study include improving monitoring through a real-time monitoring system and integrating measurement data to support more precise and adaptive distribution planning based on field conditions. The practical implications of this study are that a structured and data-based material distribution monitoring system is very relevant to be applied to infrastructure projects in areas with limited access, such as hilly areas, remote villages, or disaster-prone areas. With this system, project implementers can anticipate distribution obstacles more accurately, reduce the risk of delays, and maintain the quality and continuity of development as a whole.

Abstract

The installation of electrical and sanitary installation pipes in reinforced concrete columns forms holes that reduce the effective cross-sectional area and decrease the column capacity. This study compares the strength of perforated columns with varying shear reinforcement diameters to columns without holes. One of the reinforcement efforts was to increase the diameter of shear reinforcement to increase the resistance to axial load. The specimens measured 120 x 120 x 450 mm, consisting of six specimens: three columns without holes and three perforated columns with variations in shear reinforcement. The experimental method was used by testing materials, concrete compressive strength, and short columns at the Banyuwangi State Polytechnic Laboratory from January to June 2025. The test results showed that the columns without holes were able to withstand an axial load of 296.71 kN, 16.79% more than the perforated columns which were only able to withstand 246.89 kN. Theoretically, the column without holes has a compressive strength of 327.501kN, 3.4% greater than the perforated column of 316.531kN. The results show that increasing the diameter of shear reinforcement does not significantly increase the axial capacity of short hollow columns. Consideration of the use of diagonal shear reinforcement as additional reinforcement in addition to increasing the diameter of shear reinforcement against axial load is a crucial aspect in the optimization of hollow column design.

Abstract

This study was conducted to determine the impact of street vendors (PKL) on the capacity and performance of the road on Jalan Ki Hajar Dewantoro. This location was chosen due to problems arising from the existing road conditions. This study will use the MKJI 1997 method, in the form of geometric surveys and traffic volume surveys to determine road conditions. The survey will be conducted twice a week, namely on Tuesdays and Sundays. The survey will be conducted for 12 hours a day. In addition, the calculation of road capacity and performance also uses MKJI 1997, where the calculation results in a capacity value before the presence of street vendors of 2644.2 pcu/hour, while after the presence of street vendors the capacity value decreased to 1661.9 pcu/hour. This capacity value has experienced a significant decrease. Thus, it will affect the performance of Jalan Ki Hajar Dewantoro. This can be seen in the decrease in the level of service on the road section. From the calculation results, the value of the level of service decreased in the afternoon period, where the value of the level of service from A to B, this means that traffic conditions become denser.

Abstract

The concept of Transit Oriented Development (TOD) is an urban planning approach that emphasizes the integration of public transportation and land use to create sustainable, efficient, and pedestrian-friendly urban areas. This study aims to analyze the level of conformity in the implementation of the TOD concept in the Tugu Station area of Yogyakarta. The data collection methods employed include direct observation and documentation, while the analytical method adopts TOD indicators based on guidelines from ITDP (2017), the Florida TOD Guidebook (2012), and the Indonesian Ministry of Agrarian Affairs Regulation No. 16 of 2017. The assessment of conformity was carried out by measuring variables such as building density, land-use mix, pedestrian network quality, and integration of transportation modes. The results indicate that certain aspects of the area meet TOD criteria, such as the availability of pedestrian pathways and diversity in land use functions. However, deficiencies were also identified in parameters such as pedestrian connectivity, area density, and infrastructure for non-motorized transport. The TOD evaluation score for the Tugu Station area in Yogyakarta was found to be 40.1%, which falls into the bronze standard category, indicating that TOD development in the area is still at an early stage. Although efforts have been made to provide access to public transportation, further improvements are required to meet higher standards, particularly in the indicators of density, land-use mix, walkability, and cycling infrastructure. This research is expected to serve as a reference for transit-oriented area development in other Indonesian cities facing similar challenges in integrating transportation and land use.

Abstract

Depok City as a city with significant population growth every year requires vertical housing infrastructure to meet the needs of housing. The construction of a 3-storey house requires a strong structure and is in accordance with user safety rules so that it can support vertical and lateral loads and is efficient in terms of work procedures and cost factors. Therefore, the selection of implementation methods for structural work is a crucial thing that needs to be studied in terms of quality factors and costs that will be incurred. This study provides alternative recommendations for selecting implementation methods for 3-storey house structural work items with an evaluation of the methods implemented and the costs incurred. The implementation methods provided include structural work using instant concrete, mini mix concrete, steel structures, and containers. From the results of the evaluation carried out, in terms of the cost of structural work, the recommended implementation method is to use instant concrete with a total cost of Rp157,254,996.90. This method is recommended because the costs incurred are more economical, there is no need for mobilization of heavy equipment such as cranes and truck mixers, and it does not have the potential to interfere with access for residents around the construction site. The implementation methods that are less recommended are using mini mix concrete with a total cost of Rp150,190,417.15, steel structures with a cost of Rp292,455,790.28, and containers with a cost of Rp76,900,000.00 taking into account access to the project location, mobilization of heavy equipment, and the costs incurred.
