Abstract

The integration of the Trans-Java Toll Road has triggered induced demand and batch arrival patterns at the Ketapang Ferry Port, potentially creating structural bottlenecks due to space limitations. This study aims to determine the ideal capacity of the 6,170 m² ready-to-load parking area at LCM Piers (IV, V, and VI) to mitigate vehicle queues using a dynamic system simulation method (Powersim). Evaluation based on daily operational data for normal conditions and the peak season for the March 2026 Eid al-Fitr transportation period indicates that parking performance is ideal for the Class VII vehicle scenario with a Density Index of 0.57 (57% utilized), leaving 2,651 m² of idle space. Conversely, in the Class VIII vehicle scenario, land space utilization reaches saturation with a Density Index of 0.98 (98% utilized), leaving only 2% of the remaining space (123 m²). This critical condition triggers the highest level of warning (critical alarm), because a minor delay in the ship loading process will immediately cause a queue of vehicles to overflow outside the port authority or national road

Abstract

I Gusti Ngurah Rai International Airport in Bali is an international airport with high air traffic volume and complex runway approach characteristics due to its coastal geography. This study aims to design a Category II Precision Approach Lighting System (PALS) for Runway 27 to enhance flight safety during low-visibility conditions. The research methodology employs a field observation approach, analysis of lighting configurations based on ICAO Annex 14, evaluation of obstacle limitation surfaces (OLS), and the integration of the Tri Hita Karana concept as an environmental and cultural safety approach rooted in Balinese traditions. The results indicate that a 900-meter-long PALS CAT II configuration with a sequenced flashing light system effectively enhances visual guidance for pilots during the final approach phase. The integration of the Tri Hita Karana concept supports harmony between aviation safety, coastal environmental sustainability, and local Balinese cultural values. This research offers a novel approach by combining technical aviation lighting system methodologies with culture- and environment-based safety concepts. The implementation of this system is expected to support low-visibility operations and elevate international aviation safety standards at I Gusti Ngurah Rai International Airport in Bali

Abstract

Background: Tooth discoloration is a common aesthetic problem and can affect self-confidence. One solution to this problem is a tooth whitening procedure, using either chemical or natural ingredients. Objective: To compare the effectiveness of strawberry juice and blueberry juice on tooth discoloration during the teeth whitening process. Methods: This was a laboratory experimental study using a pre-test and post-test control group design. Twenty-four permanent first and second premolar teeth were immersed in red grape extract and green grape extract for 1, 3, and 5 hours, respectively. Tooth color was measured before and after immersion using a VITA Easyshade V digital spectrophotometer, based on L (lightness), C (chroma), and H (hue) values. Results: The study showed an increase in L values and a decrease in C and H values, indicating a significant difference in tooth color (sig <0.05) across all immersion groups, using both strawberry juice and blueberry juice. The most significant increase in L values occurred in the 5-hour soaking group with strawberry juice. Conclusion: There is a difference in effectiveness between strawberry juice and blueberry juice in the tooth whitening process. Strawberry juice is more effective as a natural external tooth whitening agent, especially with longer soaking times, due to its active ingredients such as malic acid, electic acid, vitamin C, and phenolic compounds. There is also a difference in pH between strawberry and blueberry juices. The pH value of strawberry juice is lower than that of blueberry juice

Abstract

This study explores science teachers’ perceptions of integrating virtual laboratories (VLs) in science education using a literature review methodology. A systematic process of identifying, screening, and analyzing relevant studies was employed to synthesize existing findings. Results indicate that science teachers generally have positive attitudes toward VLs, recognizing their potential to enhance conceptual understanding, engagement, and higher-order thinking skills. VLs are considered flexible and innovative tools that can supplement or partially replace traditional laboratories. However, their actual implementation remains limited due to challenges such as inadequate infrastructure, limited teacher training, and lack of institutional support. These constraints create a gap between positive perceptions and actual practice. The study highlights the need for continuous professional development, improved resources, and supportive policies to strengthen the integration of VLs in science education

Abstract

Deep learning integrates three key aspects: mindful learning, meaningful learning, and joyful learning. The deep learning model is capable of identifying complex patterns through discussions, experiments, projects, and understanding the rationale behind each topic studied, thereby producing a profound and enjoyable learning experience. This study examines deep learning as an effort to instill character in students, which also requires meaningful integration between cognitive, affective, and psychomotor domains. To achieve a mindset transformation, practical actions are needed that progress from being able but forced, to becoming accustomed, and eventually forming attitudes or character. This research employed a qualitative method. Data were collected through interviews, observations, and documentation. Data analysis was conducted using the Miles and Huberman framework, and the findings were presented descriptively. The results show that two aspects—mindful learning and meaningful learning—are more suitable to be given greater emphasis in the learning process to strengthen students’ character education

Abstract

Primary umbilical endometriosis is an exceptionally rare extragenital manifestation often misdiagnosed due to its clinical similarity to other umbilical masses, especially in patients without prior pelvic surgery. This study aims to analyze the diagnostic process and surgical intervention effectiveness in a perimenopausal patient. A qualitative descriptive case study was conducted on a 52-year-old woman selected via purposive sampling. Data were gathered through longitudinal clinical documentation, including medical history, physical examination, and radiological evaluations (ultrasound and CT scans), confirmed by histopathological reports. Results identified a 3.16 × 3.37 × 2.8 cm hypoechoic solid mass with peripheral vascularization and increased post-contrast density, manifesting as cyclic bleeding. Management through wide excision successfully achieved total removal, with histopathology confirming umbilical endometriosis and no recurrence during a one-year follow-up. This study concludes that primary umbilical endometriosis should be a primary differential diagnosis for umbilical masses presenting with cyclic bleeding. Its practical contribution emphasizes integrating imaging with histopathological confirmation as the gold standard, highlighting wide excision as a definitive therapeutic modality for optimal clinical outcomes and prevention of recurrence
