Public facility cleanliness is a reflection of cultural values and collective social responsibility. Bus stops, as daily transit points for thousands of commuters, often face declining cleanliness due to limited user participation and management. This community service program was conducted on April 22, 2026, at RSAL Bus Stop, Surabaya, Indonesia, with one researcher as the sole implementer. The objectives were to improve physical cleanliness, provide environmental education, and enhance aesthetics through greening. The method consisted of three activities: installing cleanliness reminder posters, cleaning the bus stop area, and adding ornamental plants in flower pots. Evaluation employed qualitative descriptive techniques, including observation, photographic documentation, and informal interviews. Findings revealed that the bus stop floor, initially littered with plastic waste, cigarette butts, and dry leaves, became clean after sweeping. Posters were successfully placed in visible positions, and three flower pots containing Sansevieria trifasciata and Epipremnum aureum created a fresher atmosphere. Users responded positively, noting improved comfort and cleanliness. The synthesis indicates that simple interventions by a single individual can generate meaningful improvements when combining physical cleaning, visual education, and greening. This initiative demonstrates that small-scale university-led social responsibility programs can serve as replicable models for sustainable public facility management.

Urban mobility in Surabaya faces serious challenges due to the high ownership of private vehicles and the low use of public transportation. The Surabaya City Government launched Suroboyo Bus Electric in November 2024 as a sustainable transportation innovation on the Purabaya–ITS route. This study aims to analyze commuter preferences for the Suroboyo Bus Electric mode over private vehicles, by emphasizing functional factors (cost, travel time, comfort) and symbolic factors (status, identity, modern image). The research method used a quantitative descriptive approach with 400 respondents, primary data was obtained through questionnaires, while secondary data came from government documents and literature. The analysis was carried out through descriptive statistics, chi-square tests, and logistic regression. The results showed that the majority of respondents chose Suroboyo Bus Electric as the main mode (62%), with the dominance of young, middle-income users, and mostly women. Most of the respondents have one unit of private vehicle, but still use electric buses as a mode of complementing mobility. Travel destinations are dominated by social, economic, and educational activities, with an average travel time of 16–30 minutes. In terms of cost, more than half of the respondents spent Rp 5,000-Rp 10,000 per trip, indicating the affordability of fares. Symbolic factors also play an important role, where Suroboyo Bus Electric is perceived as a modern, clean, and sustainable city identity.

Kebutuhan akan angkutan umum berbasis rel berdampak luas terhadap pertumbuhan penduduk dan aktivitas ekonomi Jakarta. Penelitian ini bertujuan untuk membandingkan KRL Commuter Line dan MRT Jakarta dari dua aspek Kemampuan Membayar dan Kesediaan Membayar. Analisis ini dilakukan dengan pendekatan studi literatur deskriptif-komparatif. Jurnal, prosiding, tesis, dan dokumen kebijakan yang digunakan sebagai sumber sekunder melalui analisis konten. KRL dengan tarif dasar sebesar Rp. 3.000,- mendapatkan ATP Rp. 3.770,- – Rp. 4.825,- dan WTP Rp. 3.974,- – Rp. 5.057,-, yang berarti KRL berpotensi untuk perubahan tarif sebesar Rp. 770,-. MRT Jakarta untuk tarif sebesar Rp. 14.000,- untuk fase 2A, ATP menunjukkan daya beli Rp. 17.044,- dan WTP Rp. 19.000,-. Pola penumpang terikat muncul dan sangat bergantung, di sisi ujung, dengan WTP yang tinggi dan ATP yang rendah, untuk kedua moda, menandakan MRT dan KRL sangat efisien dan nyaman. Penelitian ini berpendapat agar penyesuaian tarif dilakukan dan untuk jangka panjang, tarif perlu diikuti dengan peningkatan mutu pelayanan dengan penyesuaian yang progresif dan sesuai dengan penghasilan bagi masyarakat berpendapatan menengah ke bawah, agar mutu pelayanan tidak berkualitas rendah.

This study aims to determine factors including age, gender, education, tenure, and knowledge associated with the PPE use behavior of health workers at PT Kereta Commuter Indonesia. The study was conducted using a cross-sectional design with a quantitative approach. The sample consisted of 60 employees of the PT Kereta Commuter Indonesia Health Unit selected through total sampling. Primary data was collected using a questionnaire of OHS knowledge and behavior including age, gender, education, tenure and knowledge. Data analysis was performed by chi square test with the limit of significance used (P < 0.05). A total of 91.7% of health workers aged 18-35 years and as many as 98.3% of health workers had good knowledge by univariate analisys. There is a significant relationship between the age factor and the PPE use behavior of health workers with the results (p=0.039) and the knowledge factor with the PPE use behavior of health workers with the results (p=0.006). Age and knowledge of health workers at PT Kereta Commuter Indonesia have an influence on PPE use behavior. The company needs to develop programmed education and training, including supervision, monitoring and evaluation activities by management to increase motivation for implementing OSHs culture.

The application of safety is an important matter in carrying out activities inland transportation including railroad transportation. Jabodetabek travel routes are handled directly by PT. Kereta Komuter Indonesia. This activity certainly requires a lot of human labor so safety is very important in this regard. With the existence of safety arrangements, it will avoid any related things from accidents or losses due to the delay in the completion of work caused by the inaccurate company safety management system. Therefore each element involved in each activity requires further knowledge and understanding of the core factors that are in accordance with the safety management system used. Referring to this approach, research is carried out on the railroad industry in Indonesia by developing a safety model in the railway industry. The research was conducted by finding the right literature and then developing a model for the factors considered appropriate to be applied to the safety management system in railroad transportation in Indonesia. After the model was developed, the model was confirmed by the Confirmatory Factor Analysis (CFA) approach with the Structural Equation Modeling (SEM) method. The results of the study will prove that the factors developed in the safety model are positively related to the implementation of commuter train safety management in Indonesia.  

The transport industry stands out as a crucial domain in bolstering Indonesia's journey toward economic revitalization, swift progress, and equitable distribution. At present, Indonesia is in the process of establishing a high-speed railway sector that adheres to global benchmarks. Rail-based transit systems exert considerable influence on the mobility of both individuals and commodities. Trains possess the capacity to convey substantial volumes of commuters and freight in one journey, thereby playing a role in diminishing operational expenses for transportation fleets. Braking is an important aspect of driving because it affects safety, vehicle control, and vehicle efficiency. In order to develop braking research, high-speed train braking test equipment is needed to describe the actual conditions during braking. High-speed trains are a type of train capable of traveling at speeds above 200 km/h. The braking applied to these high-speed trains involves several combined forces, including regenerative braking and pneumatic braking. In regenerative braking, deceleration occurs due to the conversion of kinetic energy into electrical power. This mechanism is carried out when the train is at an operational speed of 220 km/h until it decelerates to 160 km/h. Next, pneumatic braking was applied at a speed of 160 km/h until the train slowed down and came to a stop. This study shows how the calculation process was carried out using a scale of 1:4 at a speed of 160 km/h.

The purpose of this research was to determine the campaign management of a company in an effort to maintain the company's image. In this research, it examined the management of Public Relations campaigns at PT. Indonesian Commuter Train by carrying out an Anti-Sexual Harassment and Violence campaign. The reason for conducting this research is that in Indonesia cases of sexual harassment are very common, almost every year cases of sexual harassment increase, apart from that, one of the criminal acts that is often worried about by KRL commuter line passengers is sexual harassment. Therefore PT. Kereta Commuter Indonesia is carrying out a Public Relations campaign which aims to raise awareness of KRL users regarding the issue of sexual harassment and violence on public transportation. This research uses theories that are relevant to what is being studied, namely campaign management theory (Venus: 2019), as well as corporate image theory (Kotler and Keller: 2013). The method used in this research is descriptive qualitative, the data collection technique used in this research is primary data in the form of interviews with informants and secondary data in the form of documentation, both data and images. With the results of campaign management used by Public Relations PT. Kereta Commuter Indonesia in maintaining the company's image through answers obtained through source triangulation, it was stated that the campaign carried out could educate and minimize sexual harassment and violence within the KR environment and this campaign also had an impact on PT's corporate image. The Indonesian Commuter Train is considered to care about issues related to sexual harassment and violence experienced by KRL users. The inhibiting factor in this anti-sexual harassment and violence campaign is the sexual harassment and violence campaign run by Public Relations PT. The Indonesian Commuter Train has not been fully implemented by KRL users because there are still many cases of harassment that occur in the KRL environment. The supporting factor is that many agencies are participating in this campaign, such as the Loreal brand, they are making talk shows about sexual harassment and violence.

Abstract. Public transportation is often considered a practical solution for reducing traffic congestion. However, initial surveys conducted after implementing the TEMAN Bus service along Corridor 2 showed low enthusiasm among commuters. Only 14.103% of them used the service. This study aims to identify areas for improvement to increase public interest in utilizing this service. Corridor 2 runs from Mall Panakkukang to Sultan Hasanuddin International Airport and vice versa. The study focuses on four main categories of variables: service level, service quality, socialization/information, and stop services. To assess public interest in the TEMAN Bus service along Corridor 2, this study used observations and distributed questionnaires. The questionnaire data was then analyzed using Structural Equation Modeling (SEM) after undergoing validity and reliability tests. The study found that the variable of stop services was the primary factor contributing to the low level of public interest.
