The findings reveal that the airport has provided several tourism-supporting facilities, including ground transportation services, food and beverage outlets, as well as souvenir and gift shops. However, the implementation of these facilities has not yet reached optimal performance. Identified challenges include the limited choice of transportation options to and from various tourist destinations, the lack of authentic Lake Toba culinary offerings at food and beverage outlets, and the insufficient promotion of local products at souvenir shops. Furthermore, the absence of essential services such as travel agencies and money changers has negatively affected convenience, particularly for international tourists who require accessible information, transactions, and travel services. These findings indicate that improving supporting facilities at Sisingamangaraja XII International Airport is an urgent necessitySuch efforts are expected to enhance the quality of airport services, increase tourist satisfaction, and ultimately reinforce Lake Toba’s position as a leading national and international tourism destination.

This study aims to explore guest experience as a benchmark for service quality in four-star hotels in Bali. Using a qualitative phenomenological approach, the research was conducted at two representative hotels, namely Four Points by Sheraton Bali, Kuta and The Anvaya Beach Resort Bali. Data were collected through semi-structured in-depth interviews with 20 guests who had stayed for at least one night within the past six months, online review analysis from platforms such as Booking.com and TripAdvisor, as well as participatory observations in service areas.The findings reveal that the dimensions of service quality most influencing guest experience include staff responsiveness, facility comfort, and the authenticity of services that integrate local culture. Guests appreciated staff friendliness and professionalism, room cleanliness, and personal touches such as being greeted by name or receiving special attention, which created positive emotional experiences. However, several weaknesses were also identified, such as delays in room service during peak hours and inconsistent maintenance of facilities. These results are consistent with the SERVQUAL model (Parasuraman et al., 1988), which emphasizes five key dimensions, but this study highlights the emotional experience dimension, which has been less explored in hospitality research in Bali. This study makes a theoretical contribution by broadening the understanding of the relationship between service quality and guest experience, particularly in the context of four-star hotels that are characterized by high service standards and intense competition. The practical implications suggest that hotel management should strengthen service personalization, ensure consistency in staff reliability and responsiveness, and enhance the integration of local cultural values as a differentiation strategy to increase competitiveness. Thus, guest experience can serve as a primary indicator that not only reflects service quality but also builds customer loyalty and strengthens the hotel’s positive image among both domestic and international tourists.

This study aims to determine the significant influence of mathematical resilience on students' mathematical problem-solving ability, as well as measure the magnitude of this influence.

This study aims to explain the procedure for processing the Notice of Readiness (NOR) document for coal-carrying vessels at PT. Armada Lintas Baruna Bandar Lampung and to identify the consequences that occur when the NOR is submitted late or contains inaccuracies. As vessels from international shipping companies frequently call at Indonesian ports to transport coal abroad, companies must continuously improve service efficiency and reliability to support national shipping and trade performance. PT. Armada Lintas Baruna plays a key role in managing export vessels, particularly coal carriers, from loading ports to their country destinations, and the NOR serves as a crucial document through which the Ship Master declares that the vessel is fully prepared to load or discharge cargo during the charter period. The NOR service process includes several stages: verification of vessel readiness by the agent, preparation and submission of the NOR document, verification by the port authority, issuance of NOR confirmation, and document closing. Delays or errors in NOR submission can disrupt the vessel’s operational schedule, potentially causing financial losses for shipowners through demurrage charges. This paper employs both field research and library research to provide an in-depth understanding of the NOR service mechanism.
