One of the classic problems of Semarang City as a metropolitan city is related to the arrangement of the transportation system until now not resolved comprehensively. The arrangement of transportation in Semarang City as a trigger for the emergence of problems disproportionate number of vehicles to the number of passengers or residents compared to the volume of roads passed by motorized vehicles in Semarang City. With the increasing population of Semarang City on the one increasing motorized vehicles, the increasing number of motorized vehicles if not balanced with the number or volume of roads passed by motorized vehicles every day, every hour has the consequence of congestion and chaos on several roads in Semarang City. Referring to these conditions, the Semarang City Government is trying to overcome transportation problems by organizing road-based public transportation known as BRT or Bus Rapid Transit Trans Semarang which was first rolled out on September 18, 2009. The legal aspects that underlie the BRT (Bus Rapid Transit) Trans Semarang service are Law No. 22 of 2009, No. 25 of 2009. The Trans Semarang Bus Rapid Transit (BRT) service is expected to address transportation management issues in Semarang, a growing metropolitan city. In this qualitative study, the researcher describes the quality of BRT implementation in Semarang from a legal perspective.

Inclusive education requires learning approaches that are not solely oriented toward academic achievement but are also capable of supporting the psychomotor and emotional development of students with special needs, including those with mild intellectual disabilities. Students with mild intellectual disabilities commonly experience limitations in motor coordination, emotional regulation, and attention focus, which necessitate adaptive, holistic, and experiential learning strategies. This study aims to describe the implementation of contemporary dance as an art therapy approach in supporting the psychomotor and emotional development of students with mild intellectual disabilities in an inclusive school setting. The study employed a quantitative approach using a Single Subject Research (SSR) method with an A–B–A design. The research subject was one ninth-grade student with mild intellectual disability at SMPN 1 Karangtengah. Data were collected through systematic observation during the baseline-1 (A-1), intervention (B), and baseline-2 (A-2) phases, using indicators of psychomotor and emotional development. The results showed improvements in motor coordination, movement fluency and balance, imitation ability, attention focus, and emotional expression during the intervention phase. In the baseline-2 phase, most of the acquired abilities were maintained despite the termination of the intervention, indicating stability in behavioral changes. These findings suggest that contemporary dance as an art therapy approach has the potential to serve as a relevant and effective pedagogical-therapeutic strategy in supporting the psychomotor and emotional development of students with mild intellectual disabilities. The implications of this study indicate that contemporary dance can be integrated into arts learning or Individualized Education Programs as a humanistic learning alternative oriented toward students’ developmental needs within inclusive education contexts.

This research examines the practices of a B4 class teacher at RA Takhrimah Tungkop in identifying children’s Multiple Intelligences (MI) through authentic observation during an activity of printing moon shapes using banana stems. The study employed a descriptive qualitative approach with data collected through in-depth interviews and participatory observation. Data were analyzed thematically and supported by source and technique triangulation to ensure the validity of the findings. The results indicate that the teacher’s understanding of the MI concept was still focused on linguistic, logical-mathematical, and visual-spatial intelligences. Despite this limited conceptual scope, the implementation of authentic observation during the art-based activity successfully revealed a broader range of children’s intelligences. The moon-printing activity demonstrated indicators of visual-spatial intelligence through shape recognition and composition, bodily-kinesthetic intelligence through hand–eye coordination and motor control, and intrapersonal intelligence reflected in children’s ability to manage emotions, maintain focus, and show persistence during the task. Repeated observations accompanied by anecdotal records enabled the teacher to construct individual and continuous MI profiles for each child. These profiles can be utilized to design more varied, contextual, and child-centered learning strategies that align with the characteristics of early childhood learners in the Raudhatul Athfal setting. The practices observed also illustrate the connection between Gardner’s MI theory and Islamic early childhood education grounded in concrete learning activities. The findings support the development of child-friendly learning environments and encourage teacher creativity in conducting activity-based assessments. This study recommends strengthening teacher competencies through training in authentic MI assessment and further research using a research and development approach.

This study investigates how puzzle games affect the fine motor development of young children. This study uses a quantitative approach and a quasi-experimental design. The study involved 30 children aged between 4 and 6 years who were divided into two groups: an experimental group and a control group. The experimental group received an intervention in the form of puzzle-playing activities for four weeks, with an interval of two to three times a week. On the other hand, the control group did not receive any special treatment for routine learning activities. To collect data, standardized fine motor skills test instruments were used. These included eye-hand coordination, finger movement control, precision, and the ability to assemble and copy shapes. A t-test was used to analyze the data to determine the difference in results between the two groups. The results of the study showed that the experimental group and the control group differed significantly. Compared to children who did not receive treatment, children who were involved in puzzle-playing activities showed greater improvement in all fine motor indicators. The results show that puzzle games can be used effectively as a learning tool to help the fine motor development of early childhood develop well.

According to Sigmund Freud's psychoanalytic theory, mental disorders occur due to conflicts between the id, ego, and superego that give rise to anxiety and abnormal behavior. At the Pamardi Raharjo Banjarnegara Social Service House, this conflict is diverted through a skills guidance program that aims to improve the independence and quality of life of Beneficiaries (PM). The program includes training in doormat crafts, salted egg making, paving blocks, and flannel crafts, each of which is guided by a dedicated mentor and followed by a stabilized PM. The activity of making mats aims to train motor skills and social interaction and produce products with selling value. The making of salted eggs not only teaches production skills, but also fosters confidence and economic independence. Paving block activities are more focused on motor training and cooperation between PMs even though they are not yet worth selling. Meanwhile, flannel handicrafts guided by Mbak Retno became a new activity that provided space for expression and creativity. All of these activities are designed to distract PM's passive behavior and equip them with useful practical skills after leaving the orphanage. Thus, skills-based approaches have proven to be effective in supporting the overall rehabilitation and empowerment process of PM.

This study aims to design and test a Dual Axis Solar Tracker to improve the energy absorption efficiency of solar panels on ships. The system is designed with a two-axis movement mechanism (horizontal and vertical) using a linear actuator motor controlled by Arduino Nano and ESP32. Testing was conducted on a 20 WP solar panel in Surabaya for 30 days, divided into three methods: 10 days using an LDR sensor, 10 days using an RTC, and 10 days in static conditions without a sensor. Voltage, current, and power data were measured every 30 minutes at 07.00–17.00 WIB. The test results show that the RTC method provides the highest and most stable output power, according to the sun's movement patterns in tropical areas, while the LDR method responds quickly to changes in light intensity but is less stable in changing weather. Static installation produces the lowest power. This system is able to maintain the panel orientation perpendicular to the sun's rays, thus increasing energy efficiency compared to static systems. These findings prove that dual-axis solar tracker technology, especially with an RTC sensor, is effective in dynamic maritime environments and can be a practical solution for optimizing renewable energy on ships. The most effective results using RTC sensors demonstrated the most stable and high power output, especially since the sun in tropical areas like Surabaya moves fairly consistently following a cyclical pattern. The success of this system not only increases the energy output of solar panels but also provides a practical solution for renewable energy applications in tropical climates.
