Fri, 28 Nov 2025 14:56:27 +0700

The development of H. Asan Sampit Airport is a strategic step to support increased mobility, economic growth, and regional connectivity in East Kotawaringin Regency. Based on the analysis of demand projections, the number of passengers is expected to increase to 2,300 passengers per day by 2035, or an increase of more than 90% compared to 2018 conditions. However, the current infrastructure condition is inadequate, characterized by a PCN value of only 24/F/C/X/T, well below the minimum standard of 45–50 required for a large body aircraft such as the Airbus A320. This study uses descriptive qualitative methods and Fishbone analysis to identify the root of the problem which includes human aspects, methods, machines, materials, environment, and management. The results of the study show the need to increase the runway to 2,250–2,400 meters, increase the PCN, expand the terminal, and modernize facilities according to ICAO Annex 14 standards. With the right infrastructure and managerial interventions, H. Asan Airport has the potential to increase the regional economic contribution by 0.8–1.3% of GDP per year.

Andini Kharisma Firdausi, Dwijoko Ansusanto — Fri, 28 Nov 2025 15:07:47 +0700

The growth in the number of motor vehicles and community activities in Yogyakarta City put great pressure on the transportation system, which has an impact on the increasing number of traffic accidents. The high accident rate shows the need to identify vulnerable locations as a basis for the preparation of prevention strategies. This study aims to identify accident-prone locations in the city of Yogyakarta through a spatial approach and formulate handling recommendations based on the results of road safety inspections. The methods used include spatial analysis using the ArcMap software-based Geographic Information System (GIS), with three main approaches, namely spatial autocorrelation analysis (Moran's I), hotspot analysis (Getis-Ord Gi), and density estimation (Kernel Density Estimation). Accident data was obtained from the Yogyakarta City Resort Police and weighted using the Equivalent Accident Number (EAN) method. The results of the analysis identified 16 hotspot points with a 99% confidence level, as well as four priority locations that require immediate handling, namely Jalan Kyai Mojo, Jalan Menteri Supeno, Jalan P. Diponegoro, and Jalan Brigjen Katamso. The results of road safety inspections show that there are problems such as damage to the road surface, markings that are not clearly visible, lack of traffic signs, and misuse of sidewalks. Handling recommendations include repairing road infrastructure, repainting markings, adding signs and crossing facilities, and restoring sidewalk functions for pedestrians. It is hoped that the implementation of this recommendation can reduce the accident rate and significantly improve traffic safety in the city of Yogyakarta.

The growth of tourism in Yogyakarta City has led to an increase in the need for tourist terminal facilities that are able to regulate the movement of tourist buses in a more orderly, efficient, and safe manner, especially in the strategic area of Gumaton (Tugu-Malioboro-Kraton) which has the highest rate of visits in the city. This research aims to determine the most ideal location for the development of tourist terminals through spatial analysis approaches, field surveys, SWOT analysis, and Analytic Hierarchy Process (AHP) methods. Primary data was obtained through surveys of bus movements at five main intersections, physical observation of road sections, and distribution of questionnaires to tourists, bus drivers, the community, business actors, and government stakeholders. Meanwhile, secondary data was obtained from the Yogyakarta City RTRW, tourist visit statistics, and transportation regulations. The AHP assessment criteria include accessibility, RTRW suitability, transportation network integration, land availability and technical feasibility, traffic and safety impact, and environmental sustainability. The AHP results showed that the Giwangan Terminal obtained the highest score of 59.75%, followed by the Ngabean crime scene at 27.28%, Jalan Margo Utomo at 7.20%, and Jalan Jenderal Sudirman at 5.78%, with a Consistency Ratio (CR) value of 0.033 which indicates the consistency of a valid matrix. This finding is strengthened by SWOT results which show that Giwangan has significant advantages in terms of land availability, accessibility, and spatial suitability. Thus, Giwangan Terminal is designated as the most feasible location for the development of Yogyakarta City tourist terminals in the short and long term.

Damardjelang Ramadhan, Eva Elviana — Fri, 28 Nov 2025 15:12:31 +0700

The development of the creative economy sector in Indonesia encourages the presence of public facilities in the form of Creative Centers as a space for collaboration, production, and development of creative communities. However, questions arise whether the facility has been truly inclusive and able to accommodate all groups of people, including people with disabilities. This study aims to examine the application of inclusive architecture in the Malang Creative Center (MCC) building through a descriptive-qualitative approach. Data were obtained through field observation on the exterior and interior areas of buildings, as well as literature studies related to the principles of Universal Design and accessibility standards of the Minister of PUPR No.14/2017. The results of the study show that the application of the principle of inclusivity in MCC is in the category of being quite appropriate. Facilities such as elevators and disabled toilets have met some Universal Design principles, but important elements such as guiding blocks, contrast signage, braille handrails, and pedestrian connectivity to buildings have not been met. Based on the conformity evaluation, as many as 4 components were classified as partially compliant, 4 components were not compliant, and only 1 component was considered compliant. These findings are expected to be considered for the development of Creative Center facilities that are more inclusive, safe, and friendly for all users.

This study analyzes flood levels for the 2025 re-period in the Grand Madani Housing area, Gunung Gedangan Village, Mojokerto City. The study includes hydrological and hydraulic analysis using 10 years of rainfall data (2014 – 2023) from Mojosari Station, topographic analysis (Sungai Sadar watershed) and soil type (Sub – Sadar watershed), as well as drainage design based on the Rational method, HEC – RAS,. The rainfall distribution was tested using the Log Normal, Pearson Log Type III, and Gumbel methods, and tested for compatibility with the chi-square test. The results showed that the distribution of Pearson Log Type III was most consistent with the data (kurtosis statistical value γk = 3.247). The planned rainfall for T = 2 years is 165.7 mm, and T = 100 years is 329.3 mm (Normal Log), which is used to calculate the rainfall intensity (Talbot, Ishiguro, Sherman method) and the planned flood discharge by the Rational method (Q = 0.278· C·Cs· I·A). The planned flood discharge obtained is 9,399 m³/s, greater than the existing channel capacity of 8,053 m³/s, so channel replanning is required. Hydraulic simulations using HEC – RAS 5.1 showed that the proposed drainage design (30 cm × 40 cm cover box) was able to accommodate the design rainfall (25-year re-period) without overflow. The study contributes to residential flood mitigation through the calculation of adequate plan discharge and drainage design recommendations, as well as the use of hydrodynamic models to ensure the performance of the channel to the standard.

Chairumin Alfin, Heru Setiyo Cahyono, Nur Latifah Khomsiati, Annisa' Carina — Fri, 28 Nov 2025 15:14:16 +0700

Drainage analysis and planning in an effort to prevent flooding at the Mahroja Commercial Center Tasikmalaya was carried out with a hydrological analysis method in the Cimulu River Sub-watershed, Tasikmalaya City, to estimate the planned rainfall and flood discharge for the 25-year plan. Daily rainfall data during 2007–2019 from the nearest stations (Cimulu, Cikunten II, Kawalu) were analyzed by arithmetic method to obtain the average rainfall of the area. Statistical frequency analysis was carried out by checking the match of the probability distributions of Gumbel, Log – Normal, and Log – Pearson Type III. Based on the chi-square test, it was obtained that the Type III Log-Pearson distribution provided the best match. The 25-year planned rainfall ranges from 124.48 mm (Normal), 137.74 mm (Gumbel) to 159.33 mm (Log – Pearson). The intensity of peak rainfall was calculated from the IDF (Intensity–Duration–Frequency) curve and used in the Rational method (Q = 0.278· C·I·A) to calculate the plan discharge. The hydraulic model of the regional drainage channel (Mahroja Commercial Center) was made with EPA SWMM 5.1 software (25-year planned rainfall input, DTA 18.8 ha). The results of the SWMM simulation show the value of the planned flood discharge at vital locations (namely: C8 shopping complex of 0.877 m³/s, about 37.8% of the capacity of 2.3196 m³/s; peak in channel C10 of 2.496 m³/s, 59.3% of the capacity of 4.2057 m³/s). This condition indicates that the commercial drainage system is safe against 25 years of flooding. The results of this study are important as a technical basis for flood mitigation in the Cimulu Sub-watershed – namely: planning vulnerable areas and increasing drainage capacity – so that the burden of large rainfall can be reliably overcome.

ABSTRACT

Innovation in construction methods is increasingly needed, especially in projects in extreme geographical conditions. This study analyzes the effectiveness of the precast half slab installation method in the Liang Liang Coral Beacon Tower Construction project in the Riau Islands, which is located ±4 nautical miles from Bintan Island, so that it does not allow the application of conventional casting. The half slab precast method was chosen to overcome the limitations of the working area, weather risks, and the need to accelerate construction time. The analysis was carried out through the stages of half slab design planning, fabrication, material distribution using a service barge, to the erection process using a crawler crane. The technical data of the half slab includes the configuration of HS1, HS2, and HS3 with a thickness of 200 mm and a concrete topping of 150 mm. The results of the analysis showed that the precast half slab met the technical requirements based on SNI 2847:2013 and the PCI Design Handbook, both in terms of lifting load capacity, bending moment control, and deformation during installation. The installation method has also proven to be efficient in terms of time and cost because it minimizes the use of formwork, reduces the risk of wet work at sea, and accelerates the implementation of erections. This study concludes that the half slab precast method is an effective and efficient solution for floor structure work in offshore projects, especially in locations with limited access and challenging environmental conditions.

Controlling labor productivity in construction projects has a very important role. For example, labor productivity in the early stages of a project can have a major impact on the accuracy of schedules or plans that have been prepared. This study aims to find out the process of implementing block work in the Mosque Construction Project-BKMS JIIPE Gresik and compare the productivity of labor in the installation of beam reinforcement with productivity standards as stated in the Minister of PUPR Regulation No. 1 of 2022.

Observations were carried out directly in the field by recording the number of workers, the volume of work, and the duration of time (working hours) on the B1 Block work for eight working days, starting at 07.00–11.00 WIB. The break time lasted at 11.00–13.00 WIB, and the work continued until 16.00 WIB. In addition, recording is also carried out at the end of working hours every day to obtain process data and worker productivity values.

The reinforced concrete block work in this project uses conventional methods which include the stages of preparation, measurement, ironing, formwork installation, checking, casting, dismantling of formwork, and treatment (curing) which are all carried out at the project site with the support of certain tools. The results of the observation showed that the average labor productivity (blacksmith) for the installation of B1 beam reinforcement work reached 147,390 kg/OH, while the highest productivity was 210,532 kg/OH and the lowest was 93,986 kg/OH.

The results of calculations based on the Minister of PUPR Regulation No. 1 of 2022 show that the standard productivity for blacksmith labor is 142,857 kg/OH. Based on the results of the analysis, it was found that the average productivity of workers in the field had a value of 1,031 times greater than the standard of the Ministerial Regulation on PUPR.

This condition highlights the need for adequate facilities. Therefore, this research aims to design a Fashion Center that can function as a forum for collaboration, education, training, and commercial activities to support the growth of the local clothing industry. The design applies the Modern Architectural Approach to integrate functional and aesthetic elements, creating a timeless and attractive space. The methods used are the flow chart design methodology from Goldschmidt (Analysis and Synthesis) and the Cinegram analysis method from Bernard Tschumi, which includes programmatic, footprint, and design approach analysis. The design results are expected to provide architectural design solutions that are functional, aesthetic, and adaptive to the needs of the fashion industry, while contributing positively to the local economy.

MODELING AND ANALYSIS OF RETAINING WALL STRUCTURE AT CRUSHING PLANT AT COAL PORT

Fri, 28 Nov 2025 15:22:28 +0700

The development of coal port infrastructure requires a safe and efficient structural design to support the increase in production capacity, one of which is through the construction of a crushing plant equipped with a retaining wall. This study aims to analyze the structural strength and stability of soil retaining walls that function to withstand lateral soil pressure and dynamic loads due to dumping activities in the Run of Mine (ROM) hopper area. Structural modeling was carried out using SAP2000 software by considering dead load, live load, and active ground pressure. The analysis of the bearing capacity of the foundation was carried out using the Converse-Labare, Los Angeles Group Formula, and the Seiler-Keeney Formula, while the bending moment control was evaluated against the cracking moment capacity based on the specifications of the reinforced concrete pile.

In addition, the analysis process refers to national and international planning standards, namely SNI 8460:2017 regarding geotechnical planning, SNI 2847:2019 regarding structural concrete requirements for buildings, and SNI 1727:2020 regarding minimum loads. Wall stability standards such as USACE EM 1110-2-2502 and AASHTO LRFD lateral load guidelines are also used as a reference in evaluating the stability of bolsters, shears, and bearing capacity of pile foundations.

The results of the analysis show that the retaining wall structure model consists of three main parts, namely Section 1 and 2 with a length of 10 meters and Section 3 with a length of 18 meters. In the 10-meter retaining wall structure, the total weight of the structure is 365,665 tons with a combined carrying capacity of 405,046 tons of mini square pile and spun pile, which shows a safe condition against vertical loads. The moment control results showed that the maximum working moment on the mini pile (23.842 kN·m) and the D600 spun pile (101.3516 kN·m) was smaller than the permissible crack moment, so the structure was declared safe against bending cracking. In the 18-meter retaining wall model, similar results were obtained with a larger foundation carrying capacity than the total weight of the structure and the bending moment of work that is still below the material crack limit according to the design standards used.
