Introduction & Objective: Traffic congestion and the high rate of vehicular accidents remain major challenges in developing cities such as Manado, Indonesia. The rapid increase in the number of vehicles, unmatched by adequate infrastructure, has resulted in longer waiting times at intersections, higher levels of air pollution, and an elevated risk of accidents. With technological advancements, smart traffic light systems have emerged as innovative solutions in many cities. However, their effectiveness in the context of developing cities like Manado still requires further investigation. Therefore, this study aims to evaluate the effectiveness of smart traffic light systems in improving traffic flow, reducing emissions, and decreasing the number of accidents in Manado City. Methodology: A mixed methods approach was employed, combining retrospective traffic accident data from hospitals and police records with simulation models embedded with IoT and AI technologies. The evaluation focused on key performance indicators, including waiting time, travel time, emissions, and accident probability. Key Results & Discussion: Simulation outcomes revealed reductions of up to 40% in waiting times, 25% in travel times, and 20% in emissions. Retrospective data confirmed accident clusters in high-risk intersections, particularly along Jalan A. A. Maramis. Comparative analysis with international benchmarks further demonstrated that the projected benefits in Manado are consistent with results achieved in cities that have adopted similar technologies. Nevertheless, successful implementation depends on supportive infrastructure, stakeholder collaboration, and adaptive policymaking. Conclusion & Implications: Smart traffic light systems hold significant potential as a strategic intervention to enhance road safety and traffic efficiency in Manado. The integration of localized accident data with predictive simulation models represents the main scientific contribution of this study, offering a replicable framework for other secondary cities in Indonesia. The findings also provide actionable insights for local governments to design smart mobility policies aligned with global smart city agendas.

Buildings are an essential part of human life. Building maintenance is carried out to provide security and comfort for building users. This study aims to determine and analyze the implementation of building maintenance, the influence of maintenance factors on building maintenance, and what maintenance factors have a dominant influence on the comfort of building users at PT. Campina Ice Cream Industry Tbk. This study uses a quantitative approach to data collection using a questionnaire. The population used in this study were employees at the PT. Campina Ice Cream Industry Tbk has a total of 520 employees. Meanwhile, the research sample was 72 employees at PT. Campina Ice Cream Industry Tbk. The data was tested using the validity test and reliability test. The analytical method used is multiple linear regression analysis with hypothesis testing using the t-test. The study results show that the condition of building maintenance is carried out at the factory of PT. Campina Ice Cream Industry Tbk, through architectural, mechanical, and electrical maintenance, has been carried out well, starting from wall and window maintenance and wall/glass cleaning, properly providing and maintaining health facilities, and holding office facilities and infrastructure, especially in regular electrical installations. The results of the t-test show that architectural, mechanical, and electrical maintenance has a significant effect on comfort. The building maintenance variable that has the dominant influence on comfort is the electrical maintenance variable.

The development of the telecommunications industry in Indonesia is extremely rapid. It can be seen from the telecommunications operator vendors who served as telecommunications specialist co-ops rivaling each other in giving the best service to seize the attention of the Indonesian citizen, which requires telecommunications needs. Numerous realities have developed in various regions stating that the existence of Base Tower Transceiver Station (BTS) has resistance from the residents, which are caused by health issues (radiation), safety issues, to the problem of social value. Moreover, some people from residents supported the construction of Base Tower Transceiver (BTS) since the rental price of land for the tower construction is quite high. This study uses primary data from 100 respondents. The analysis technique uses multiple linear regression analysis, which is processed using SPSS (Statistical Product and Service Solution). The next step is to test the validity, reliability, and examine the classical assumptions (including normality test, autocorrelation test, and heteroscedasticity test). In the end, it can be concluded that the people of Rungkut sub-district in Surabaya, mostly enjoyed the benefits of the construction of the existence of the Telecommunications Tower Infrastructure around them.

Gresik regency as the population increases and people use roads for their activities, accidents often occur on roads, especially in Manyar sub-district, which also has many industrial places. According to accident data for the last 4 years from the police, it was found that there was an increase and decrease in the number of accident events each year. This study uses secondary data from the local police. Then the data is analyzed using the EAN (Equivalent Accident Number), UCL (Upper Control Limit), BKA (Upper Control Limit) method, and using QGIS software to display in more detail the accident-prone areas. The results of the analysis using the EAN method obtained the highest number of accidents on Jl. Raya Manyar KM 10 is 604. For the BKA value of 384, while the UCL value is 374, from these results that the EAN value at JL Raya Manyar KM 10 exceeds the BKA and UCL values, it can be concluded that Jl. Raya Manyar KM 10 is an accident-prone area. The results of the analysis are then entered into the QGIS software to display in more detail the areas prone to traffic accidents on roads in Manyar District, Gresik.

Public transport accessibility is fundamental to sustainable urban mobility, yet conventional GIS-based spatial indicators often fail to capture commuters' lived experiences. This study integrates GIS-based and perception-based accessibility measures to provide a more comprehensive understanding of conditions in Indonesian medium-sized cities. A qualitative multiple-case study design was conducted across four cities—Malang, Mataram, Pontianak, and Kendari—involving fourteen informants including commuters, operators, planners, elderly passengers, and a person with disability. Data were gathered through semi-structured interviews, field observations, document review, and spatial analysis, then analyzed using open, axial, and selective coding alongside cross-case comparison, integrating spatial and qualitative findings. Results reveal that objective spatial accessibility and perceived accessibility are often inconsistent, producing four typologies combining high/low spatial and perceived accessibility. Key factors shaping perceived accessibility include walkability, sidewalk continuity, pedestrian safety, service reliability, waiting time, route suitability, information availability, intermodal integration, and inclusive infrastructure. Some residents near transit stops reported poor accessibility due to discontinuous pedestrian infrastructure and unreliable services, while others accepted longer walking distances when services were predictable and affordable—showing accessibility depends on the entire travel experience, not just spatial proximity. The study concludes that GIS indicators should be complemented by perception-based measures, offering an integrated framework to identify mismatches between infrastructure and commuter experience and support inclusive, user-centered transport planning in Indonesian medium-sized cities.
