Abstract

Proper planning in creating a policy is the first step needed in addressing urban transportation problems. Therefore, the Surabaya government together with Mott MacDonald and Pricewaterhouse Coopers (PwC) conducted a feasibility study to provide structured mass transportation in accordance with the target of Sustainable Development Goals (SDGs) in point 11, namely providing access to a safe, affordable, accessible and sustainable transportation system for all by increasing public transportation, considering that Surabaya is one of the priorities of the Sustainable Urban Mobility Plan (SUMP) study in the Gerbangkertosusila area prepared by the East Java Provincial Government. This study aims to determine what factors influence the shift in MRT transportation modes. The method used is logistic regression with a survey using the Stated Preference method with tariff and frequency change scenarios. The research subjects were users of private vehicles and public transportation that pass through the MRT plan route. Based on the results of the logistic regression analysis which set a p value 0.05, the attributes that influence the shift in transportation modes by private vehicles are income/pocket money with a p value <0.01, travel time from the point of origin to the destination with a p value <0.01, transportation costs with a p value of 0.014, special parking fees <0.01 and the mode of transportation used with a p value <0.01. Meanwhile, for public transportation, these attributes are ownership of a driving license with a p value of 0.017, waiting time at the bus stop with a p value <0.01, travel time from the origin to the destination with a p value <0.01 and ownership of a private vehicle with a p value <0.01Proper planning in creating a policy is the first step needed in addressing urban transportation problems.

Abstract

Interconnected public transportation plays an essential role in facilitating community mobility, especially in ensuring seamless mode transfers at integrated locations. This study aims to evaluate passengers’ expectations and satisfaction toward the integration of mode transfer services in the Suroboyo Bus public transportation system. The research was conducted at five main integration stops, namely Joyoboyo Intermodal Terminal (TIJ), Purabaya Terminal, Dukuh Menanggal Bus Stop, Marmoyo Bus Stop, and UINSA Bus Stop. The analytical methods employed in this study are the Customer Satisfaction Index (CSI) and the Importance Performance Analysis (IPA). Primary data were obtained from 250 respondents through questionnaire distribution, with the sample size determined using the Slovin formula. The results show that the CSI score of 78,16% indicating that the passengers' satisfaction level falls within the satisfied category. However, the IPA results indicate a gap between expectations and satisfaction across all indicators, with eight attributes emerging as priority areas for improvement. Therefore, it can be concluded that the integration of mode transfer services in the Suroboyo Bus system has generally met passengers’ expectations, although further improvements remain necessary to ensure a more optimal and inclusive travel experience for all users.

Abstract

Indonesia, with its vast geographical characteristics, requires efficient and sustainable long-span bridges to improve regional connectivity. This study aims to determine the optimal arch height for steel-bound arch bridges with cable network configurations and inward slopes based on structural performance. The analysis was conducted using the finite element method through SAP2000 v.25 on a 150 m span bridge with a cable angle of 74° and variations in arch height of 23 m, 24 m, and 25 m. Structural performance was evaluated based on maximum deflection and normalized structural weight on a scale of 0–1. The results show that increasing the arch height reduces the deflection from 148.55 mm to 131.41 mm with a relatively small increase in weight, which is around 0.5%. The 25 m arch height produces the best performance and is recommended as the optimal configuration for an efficient and sustainable tied arch bridge design.

Abstract

Maidenhair fern (Adiantum tenerum Sw.) is an ornamental plant with high economic value but is highly sensitive to environmental conditions, especially soil moisture, which must be maintained within 50%–80% for optimal growth. Improper cultivation, including poor drainage and fluctuating soil moisture, can cause leaf wilting, root rot, and plant death. This study uses a system design and experimental testing approach to develop a smart garden system for monitoring and automatic watering of maidenhair fern using the Blynk platform. The system integrates an ESP32 microcontroller, soil moisture sensor, relay module, water pump, and Wi-Fi connectivity for real-time monitoring and remote control. Soil moisture conditions were classified as dry (0–49%), moist (50–80%), and wet (80–100%). Results show that the pump activates below 50% and deactivates above 80%, with dry soil (42%–49%) increasing to wet levels (89%–95%) after irrigation. Relay testing confirmed that a high input consistently turns the pump on under dry conditions, while a low input turns it off under moist or wet conditions. Multi-day performance tests demonstrated stable, reliable operation, with real-time data displayed on both LCD and the Blynk application. These findings indicate that the smart garden system effectively regulates soil moisture, simplifies maintenance of maidenhair fern, and provides a practical foundation for IoT-based smart agriculture applications.

Abstract

Transportation serves as the primary enabler of mobility for Surabaya City's residents. To enhance public transport service quality, the Surabaya City Government operates the Feeder Wirawiri Suroboyo, including the FD09 route from Menanggal Terminal to Manukan Terminal. This study evaluates the operational performance of the FD09 feeder using key parameters load factor, headway, and travel time derived from route and vehicle surveys. Findings reveal that most vehicles operate below the ideal 70% load factor, with an average headway of 26 minutes, failing to meet Directorate General of Land Transportation standards. One-way travel time from Menanggal to Manukan Terminal averages 173 minutes for a round trip, and 160 minutes in the reverse direction; however, the extended headway results in excessive passenger wait times, violating service norms. The results indicate that Feeder Wirawiri Suroboyo requires service improvements, such as that routes can be rerouted with bus stop points that have high passenger demand and adding vehicles to reduce headway and waiting times, thereby better fulfilling community mobility demands.

Abstract

The advancement of information technology has increased the use of web scraping for scientific data collection, including from the SINTA (Science and Technology Index) platform, which provides researcher profiles, affiliations, publications, and citation data. However, scraping SINTA poses challenges, particularly when multiple authors share identical scores that trigger changes in display order. This instability can lead to duplicated or missing entries when using a single-pass scraping approach. This study evaluates the accuracy and completeness of SINTA author data collection by implementing repeated scraping as a strategy to handle dynamic data ordering. Experiments were conducted on the Universitas Muslim Indonesia (UMI) affiliation, targeting 915 active authors. The methodology involved page-structure analysis, spider development using Python and Scrapy, sequential scraping through pagination, and validation of data completeness and uniqueness. A three-second delay between requests was applied to maintain responsible scraping practices. The results show that a single scraping attempt failed to retrieve all authors, capturing an average of only 877.2 authors (95.86%). Due to unstable ordering, repeated iterations were required. Through 4–8 scraping cycles per trial, all 915 authors were successfully collected without duplication. These findings indicate that for platforms with dynamic data structures such as SINTA, repeated scraping provides a more reliable method for ensuring data completeness and accuracy, supporting the development of stable and responsible publication-data automation systems.

Abstract

The vulnerability of simple houses in earthquake-prone areas, particularly those built independently with limitations of key structural elements, demonstrates the need for a measurable and efficient partial rehabilitation approach. Although the reinforcement of earthquake-resistant buildings has been widely studied, the analysis of partial rehabilitation costs separating the calculations on each major structural element is still relatively limited. This study aims to compile an analysis of partial rehabilitation costs on column, ground beam, and ring beam elements by referring to the Unit Price Analysis and the Bantul Regency Standard Unit Price for Materials and Services in 2024. The quantitative method was applied using technical data from the results of MBKM internship activities at the Bantul Regency BPBD, which included the dimensions of structural elements, ironing details, and concrete quality. The calculation of material requirements and costs is carried out separately on each element to obtain a more measurable estimate. The results of the study showed that the cost of rehabilitating columns, ground beams, and beam rings amounted to Rp 14.676.740,54 each, Rp 14.213.412,00, and Rp 13.009.214,44. These findings confirm that differences in dimensions, element functions, and reinforcement methods have a direct effect on the amount of cost. This research contributes in the form of an approach to partial rehabilitation cost analysis that is applicable as a basis for technical decision-making in the planning of simple house reinforcement in earthquake-prone areas.

Abstract

Formwork in construction projects has a high level of risk to worker safety due to heavy material handling, equipment use, and activities at height. This study will investigate potential hazards in formwork through Job Safety Analysis (JSA) and assess the effectiveness of risk control based on the Hierarchy of Control, which includes elimination, substitution, engineering control, administrative control, and the use of personal protective equipment (PPE). Data collection was executed via on site observations, evaluation of project K3 documentation, and conversations with safety officers, supervisors, and associated workers. The results of the analysis indicated that risk control was more applied to engineering control (55.1%), administrative control (20.4%), and the use of PPE (20.4%). Meanwhile, of substitution (4.08%) and elimination (0%) are still very low. This condition shows that the control with the highest level of effectiveness has not been maximized, so the potential risk of accidents remains high. The findings emphasize the value of implementing top-level controls from the planning and design stages of the project. The use of Hierarchy of Control-based Job Safety Analysis has proven to be a systematic approach in determining risk control priorities and improving occupational safety management. Thus, the results of this study provide strategic recommendations for construction projects in minimizing accidents and building a more effective safety culture.

Abstract

Pedestrian crossing facilities in urban areas are often positioned without adequate consideration of actual movement patterns, leading to low utilization rates, widespread informal crossings, and increased pedestrian-vehicle conflict risks. Traditional manual observation methods for assessing crossing behavior are time-consuming, subjective, and unable to capture continuous spatial-temporal movement dynamics at scale. This study aims to develop and evaluate an automated framework for extracting pedestrian trajectories and assessing the alignment between pedestrian desire lines and existing zebra crossing infrastructure. The methodology integrates YOLO11 fine-tuned object detection with ByteTrack multi-object tracking to process unmanned aerial vehicle (UAV) video data collected at an urban intersection in Surabaya, Indonesia. Pedestrian-vehicle conflict severity was quantified using Time-to-Collision (TTC)-based surrogate safety indicators, including Time Exposed to Time-to-Collision (TET) and Time Integrated Time-to-Collision (TIT). The results reveal substantial heterogeneity in crossing behavior, with distinct spatial clustering of informal crossing hotspots located away from the designated zebra crossing. Asymmetric yet bidirectional pedestrian demand patterns were observed across the study area. Based on trajectory-derived evidence, the study recommends strategic relocation of the zebra crossing approximately 135 meters south to better accommodate natural pedestrian flow and reduce vehicular traffic exposure. These findings demonstrate that deep learning-based trajectory analysis offers a practical, objective, and scalable approach for evidence-based pedestrian infrastructure planning, particularly applicable to rapidly urbanizing contexts in developing countries where conventional assessment resources are limited.

Abstract

This research presents the development of a real-time classroom environmental monitoring system using edge computing and the MQTT protocol. The system is designed to monitor temperature, humidity, and illumination by utilizing an ESP32-based edge node equipped with DHT22 and BH1750 sensors. Data are processed locally and transmitted to an edge server running the Mosquitto broker, which stores the results and displays them through a web-based dashboard. Performance evaluation was conducted through experimental testing at distances of 5 and 10 meters, measuring delay and throughput using timestamp analysis and Wireshark traffic capture. The results show that the system operates functionally and maintains stable data transmission, with average throughput of 402.5 bps. However, the average delay of 1071.12 ms across both scenarios falls into the “poor” category based on TIPHON standards, indicating significant latency caused by Wi-Fi signal variability. Overall, the system successfully demonstrates the feasibility of edge-based IoT monitoring for learning spaces and provides a foundation for the development of smart classroom environments requiring continuous environmental supervision.
