Accessibility infrastructure is a crucial component of special school facilities to ensure safety and independent mobility for students with visual impairments (students with visual disabilities / blind students). Although national regulations provide technical standards, many special school environments for visually impaired students still show inadequate technical performance, particularly in tactile paving systems, guiding blocks, ramps, corridors, and circulation paths. Previous studies mainly identify the availability of accessible facilities for visually impaired users, with limited focus on evaluating their technical performance under actual operational conditions. This study aims to evaluate the technical performance of accessibility infrastructure specifically for visually impaired students and to formulate improvement recommendations based on field conditions. A mixed-method approach with a technical evaluation emphasis was applied through measured observations, documentation, mobility simulations involving visually impaired users, and comparison with national accessibility standards (Regulation of the Ministry of Public Works and Housing No. 14/2017). The case study was conducted at SLB Negeri 1 Bantul. The expected outcomes include a technical performance profile of accessibility infrastructure for visually impaired students, identification of critical accessibility issues affecting blind and low-vision users, and practical technical recommendations to support infrastructure improvement in special schools.

This study analyzes the impact of the implementation of pedestrian zones on the level of road services on two road sections, namely Jalan Tabaununggu and Jalan Supu Yusuf. Results Before the pedestrianization, Jalan Tabaununggu had a capacity of 2586 PCU/h per direction with a degree of saturation (Q/C) of 0.49, at Service Level C. After the pedestrian zone was enforced, the capacity decreased to 2674 PCU/h with Q/C of 0.33, which indicates an increase to Service Level B. On the other hand, on Jalan Supu Yusuf, before pedestrianization, the capacity was recorded at 2998 PCU/h per direction with a Q/C of 0.43 (Service Level B). After pedestrianization, the capacity increased to 2676 PCU/h per direction and Q/C decreased to 0.34, so that the service level increased to B. These results show that the implementation of pedestrian zones has a positive impact on the stability and efficiency of traffic flow, especially on Jalan Supu Yusuf-Tabaununggu Kendari City.

Muhammad Muhsar, Hujiyanto Hujiyanto, Suratman Aldin — Thu, 30 Apr 2026 00:00:00 +0000

The Kaledupa subdistrict, located within the Wakatobi National Park, is a marine and coastal conservation area that restricts the use of construction materials. This condition necessitates a technical study on the sustainable use of local materials. This study aims to analyze the physical characteristics of coarse and fine aggregates from Kaledupa and fine aggregates from Malaoge, as well as to compare the compressive strength of concrete using local materials and aggregates from outside the region. The research was conducted experimentally with a planned concrete quality of fc' 20 MPa. The tests included aggregate characteristics based on SNI standards and compressive strength tests on 18 cylindrical test specimens at 7, 14, and 28 days of age. The test results showed that coarse aggregates from Kaledupa met the requirements, while fine aggregates from Kaledupa did not meet the standards due to their low specific gravity and high mud content (15.22%). Fine aggregates from Malaoge also did not meet the requirements for apparent specific gravity and high water absorption (3.88%). Compressive strength tests showed that concrete with fine aggregate from Kaledupa had higher compressive strength at all testing ages, namely 14.91 MPa (7 days), 20.48 MPa (14 days), and 22.93 MPa (28 days), compared to concrete with fine aggregate from Malaoge fine aggregate, which was 11.32 MPa, 13.87 MPa, and 17.17 MPa

Analisis Tebal Lapis Tambah Perkerasan Lentur Pada Ruas Jalan Kolaka Rate-Rate

Vickky Anggara Ilham, Irwan Lakawa, Siti Mariam Aprillian — Thu, 30 Apr 2026 08:45:02 +0000

This study aims to analyze the structural capacity of the existing pavement and to determine the required thickness of flexible pavement overlay on the Kolaka – Rate-rate Road section to adequately serve traffic loads over a 20-year design life. Based on traffic survey results, the Average Daily Traffic (ADT) indicates a dominant contribution from heavy vehicles. The calculation shows a daily Equivalent Standard Axle (ESA) value of 1,322.47 ESA/day, with the largest contribution coming from 3-axle and ≥4-axle trucks. Considering an annual traffic growth rate of 5% and a 20-year design life, the Cumulative Equivalent Standard Axle (CESA) is estimated at approximately 1.60 × 10⁷ ESA. The evaluation of the existing pavement structure yields a Structural Number (SNₑₓ) of 6.96. Based on the relationship between CESA and subgrade bearing capacity (CBR 6%), the required Structural Number (SNᵣ) is determined to be 8.50. The difference between the required SN and the existing SN results in an overlay Structural Number (SNₒᵥ) requirement of 1.54. This value is then converted into the required asphalt overlay thickness using the appropriate layer coefficient

Flooding is a natural phenomenon that often causes significant losses, influenced by both natural factors and human activities. One of the flood-prone areas is Martandu Street in Kendari, Southeast Sulawesi. This study aims to analyze the drainage capacity along a 1,550 m channel using a quantitative approach based on rainfall data, channel measurements, and hydrological analysis. The results show that the design discharge (4.298 m³/s) exceeds the existing channel capacity (2.913 m³/s), indicating that the drainage system can only accommodate 68% of runoff from a 305.495 ha catchment area. To address this issue, a redesign of the channel was proposed with improved dimensions. The redesigned channel is capable of accommodating a discharge of 4.301 m³/s, ensuring effective drainage performance and reducing flood risk in the area.

This study is entitled “Geometric Evaluation of the Lanosangia–Wantulasi Road Section, North Buton Regency (Sta. 2+600–5+000).” Land transportation plays a strategic role in supporting economic growth; therefore, road geometric design must meet technical standards to ensure safety and comfort. This study addresses the issue that several road segments do not fully comply with geometric standards, particularly in terms of sharp curves and steep gradients. The objective of this research is to evaluate the existing geometric conditions, including horizontal alignment, vertical alignment, and cross-sections, based on the Guidelines for Geometric Design of Roads (PDGJ 2021) issued by the Directorate General of Bina Marga. A quantitative descriptive method was applied by comparing field data with applicable standards. Primary data were collected through field surveys using Geodetic/RTK measurements, while secondary data were obtained from related agencies. Data analysis was conducted using Digital Application Road to model alignments and calculate geometric parameters. The results show that the horizontal alignment consists of Spiral–Circle–Spiral (SCS) and Full Circle (FC) curves. Several vertical alignment segments have gradients exceeding 10%, although the overall terrain is classified as flat. The Stopping Sight Distance (SSD) meets safety standards. However, not all geometric elements comply with PDGJ 2021. This study provides recommendations to optimize road design qualit.

Irwan Lakawa, Catrin Sudardjat, Fahram Haerozi — Thu, 30 Apr 2026 08:56:58 +0000

Ahmad Yani Street in Kendari City is one of the main road segments with high traffic activity, especially during peak hours. This study aims to analyze the road performance by examining traffic volume, side friction, speed, degree of saturation, and level of service (LOS). Data were collected through field surveys for three days during morning, afternoon, and evening peak hours. The observation segment spans 200 meters, from the front of SMP Negeri 4 Kendari to the front of Ittifaqul Jama’ah Mosque. The analysis results indicate that traffic volume is higher on Segment B, influenced by the presence of a gas station and school, while Segment A experiences smoother flow due to the presence of only a mosque. The highest side friction is also found on Segment B. The free-flow speed (FFS) is recorded at 49 km/h on Segment A and 47 km/h on Segment B. The actual travel speed (VT) is 35 km/h for Segment A and 28 km/h for Segment B. The degree of saturation is 0.70 on Segment A and 0.80 on Segment B. Based on these values, the level of service for Segment A falls into category C, while Segment B is in category D. These findings indicate that Segment B's performance requires further attention to improve traffic flow.

The results showed that the highest traffic volume was recorded on Monday in Segment 1 at 742.6 smp/hour and Segment 2 at 385.8 smp/hour at 16.00–17.00 WITA. On Saturday, the highest volume in Segment 1 reached 855.2 smp/hour at 17.00–18.00 WITA, while in Segment 2 it was 389.7 smp/hour at 16.00–17.00 WITA. The average speed of light vehicles (MP) also showed variations, with the highest speed on Monday in Segment 1 at 26.2 km/hour and Segment 2 at 24.6 km/hour. On Saturday, the highest speed recorded was 25.4 km/h in Segment 1 and 25.2 km/h in Segment 2. In terms of road performance, the highest DJ value before the implementation of SSA was 0.50. After the implementation of SSA, the DJ decreased to 0.19. These results indicate that the implementation of SSA has an impact on road performance, despite a decrease in the DJ value

Analisis Pengaruh Variasi Jumlah Tumbukan Pada Campuran Asphalt Concrete Wearing Course (AC-WC) Beraspal Buton Terhadap Nilai Karakteristik Marshall

Ayu Saraswati, Andi Makkawaru Isazarni Jassin, Sri Jayani Syafitri — Thu, 30 Apr 2026 09:00:26 +0000

The quality of roads in Indonesia is greatly influenced by the type of asphalt and the way it is compactioned. One of the important things in the Asphalt Concrete Wearing Course (AC-WC) mixture is the frequency of impact during compaction, which has a direct effect on Marshall characteristics such as stability and flow. This study aims to assess the impact of variations in the number of impacts (2×25, 2×35, 2×50, 2×75, and 2×85) on Marshall parameters and determine the optimum asphalt content (OAC). The main issue is how much influence impact the impact variation has on the Marshall parameters and the KAO value. The results showed that the variation in the frequency of the collision affected all Marshall parameters. The best conditions were found at 2×75 impacts, which increased the density, stability, and Marshall Quotient values, while VIM and VMA decreased, and the flow remained within limits. This suggests that the amount of impact during compaction is critical to the quality of the mixture. The optimum asphalt content was recorded between 6.00%-6.50% with small variations (±0.50%). A collision frequency of 2×75 is recommended as an ideal condition as it provides a balance between Marshall parameters and the need for optimal asphalt grades
