Abstract

Compressive strength is one of the mechanical properties of rock behavior. This study focuses on the Balikpapan and Kampungbaru Formations located in the Kutai Kartanegara area, East Kalimantan. The Schmidt Hammer testing method was applied due to the lack of previous studies utilizing this tool to evaluate rock hardness in correlation with compressive strength. The research site is situated in the Kutai Kartanegara area, specifically in the districts of Muara Badak, Muara Jawa, and Sanga-Sanga. Field observations revealed the presence of claystone slopes at predetermined locations. Based on the test results, the uniaxial compressive strength (UCS) values for the Balikpapan Formation range from 3.453 MPa to 5.454 MPa, while the Kampungbaru Formation ranges from 3.317 MPa to 8.571 MPa. The Schmidt Hammer rebound number (RN) values for the Balikpapan Formation range from 17 to 19.6, and for the Kampungbaru Formation from 15 to 23.7. A negative correlation was found between the rebound number and UCS, where higher RN values tend to correspond with lower UCS values. This is supported by the linear regression analysis showing a negative coefficient (-0.450).

Abstract

In the Kutai Basin area, seasonal changes such as high rainfall can significantly increase groundwater content, so that the effect of water content on the shear strength of claystone, increasing water content in rocks tends to decrease shear strength. Water in the pores or fractures can increase pore water pressure and reduce effective normal stress. Shear strength is one of the most important mechanical parameters used to assess soil and rock stability, this parameter is very important in slope stability analysis, foundation planning, and various civil engineering and mining applications. Therefore, this study was conducted to determine whether the water content in rocks can affect the strength of rocks in receiving shear forces. The method used in this study is more quantitative and specific to the effect of water content on the shear strength of claystone in this area. Increasing water content in rocks tends to reduce shear strength. This study was conducted by taking claystone samples from several locations in the Kutai Basin. Data collection in the form of primary data and secondary data for testing physical properties and testing mechanical properties, in testing physical properties, the water content value will be taken as supporting data which is one of the factors that affect rock strength, in testing mechanical properties, claystone shear strength data will be taken. From the results of the physical properties test calculations, the air content in each Formation is obtained, namely, in the Kampungbaru Formation the minimum air content value is 15.54% and the maximum is 20.17%, in the Balikpapan Formation the minimum air content value is 10.21% and the maximum is 12,88%, in the Palaubalang Formation the minimum air content value is 10.49% and the maximum is 22.87%. The results of the strength of the claystone in receiving shear forces in the Kutai Basin are the Muara Jawa location 0.486MPa, Tanah Datar location 0.500 MPa, Sanga-sanga location 0.333 MPa, Muara Badak location 0.269, Air Putih location 0.711MPa, Mugirejo location 0.021 MPa and Lempake location 0.092 MPa.

Abstract

Durability is defined as a measure of a rock's resistance to weathering and disintegration when the rock undergoes weathering processes over a short period of time. The susceptibility of rocks to disintegration is related to their low durability. Rock durability is often measured using the slake durability test. The slake durability test is widely used to assess physical changes resulting from wetting-drying processes (Franklin and Chandra, 1972). Therefore, slake durability testing is conducted to understand the weathering of rocks caused by heat and water, particularly clay stones which are one of the constituent rocks on a slope. The sampling location is around Sanga-sanga and Muara Badak. Sampling was conducted with coordinate points and the Balikpapan and Kampungbaru formations. The claystone samples taken were then brought to the Mineral and Coal Technology Laboratory of the Engineering Faculty of Mulawarman University for Slake Durability tests. In this study, the lowest index value obtained was 45.7% and the highest value was 93%, indicating high to very high durability. The difference in the durability index values of claystone at the research locations indicates the presence of variables that can affect the slake durability index values of the claystone in the Balikpapan and Kampungbaru formations, including grain size and mineral content as well as geological conditions at the research site. Based on the results of the claystone durability tests, the durability index value (Id2) was obtained, indicating that the sandstone at the research location falls into the classification of high to low.

Abstract

This study aims to analyze the implementation of compensation for flight delays at Sultan Aji Muhammad Sulaiman Sepinggan International Airport, Balikpapan. This study uses a qualitative descriptive approach, with data collection techniques through direct observation, in-depth interviews with airline staff, and documentation during On the Job Training (OJT) activities. The main focus of the study is to evaluate the extent to which passenger rights have been fulfilled by airlines in accordance with applicable regulations, specifically the Regulation of the Minister of Transportation of the Republic of Indonesia Number PM 89 of 2015 concerning Handling Flight Delays. The results of the study indicate that the implementation of compensation by several airlines is still not optimal. There are discrepancies between regulatory provisions and implementation in the field, such as late delivery of information, disproportionate compensation, and uneven service among airlines. Passengers often do not receive clarity regarding their rights, and complaint mechanisms are still limited. Factors causing delays include technical problems, bad weather, inefficient operational management, and limited number and capacity of human resources on duty. This study emphasizes the need to improve the internal and external communication systems of airlines so that information related to delays and compensation can be conveyed transparently and in a timely manner. In addition, airlines need to conduct regular evaluations of standard operating procedures (SOPs), strengthen customer service training for staff, and foster synergy between work units to improve responsiveness to unforeseen situations. Regulators and airport authorities need stricter oversight and the implementation of strict administrative sanctions for violations of passenger rights. These findings provide important contributions to the formulation of public policy in the air transportation sector and provide input for improving services that are more humane, accountable, and oriented toward customer satisfaction.

Abstract

This study aims to analyze the potential utilization of empty space on the second floor of the domestic terminal of Zainuddin Abdul Madjid International Airport (ZAM) Lombok to increase revenue from the non-aeronautical sector. The background of this study is based on the importance of optimizing airport assets to support long-term financial sustainability. This is crucial considering that the aeronautical sector is highly dependent on fluctuating flight traffic. Therefore, the development of the non-aerospace sector is a strategic alternative that needs to be seriously addressed. The research method used is descriptive qualitative, with data collection techniques through direct observation on site, interviews with airport management, and documentation studies. The results of the observation indicate that there is an empty space on the second floor of the terminal, specifically between the waiting room and a row of commercial tenants, which has not been optimally utilized. This area is considered to have a strategic position and quite high passenger traffic, so it has the potential to be developed into a new commercial facility. One of the proposed developments is a photobox service business unit with a local Lombok cultural theme. This concept is considered interesting because it combines digital technology with elements of cultural tourism promotion, in line with the trend of tourist needs for documentation and unique experiences. A feasibility analysis was conducted using the Business Model Canvas approach and the 7P marketing strategy (product, price, place, promotion, people, process, and physical evidence). The results showed that this idea is feasible from both an operational and marketing perspective. The study concluded that developing a photo booth business in an empty airport area has the potential to become a new, stable, efficient, and market-relevant source of revenue. Recommendations are given to airport management to immediately realize the utilization of this area to support the airport's role as a regional economic and tourism hub.

Abstract

This study aims to analyze the role of the Terminal Inspection Service (TIS) Unit in supervising landside facilities at Minangkabau International Airport. Landside facilities include passenger terminals, drop-off areas, parking lots, and other public spaces that serve as key interaction points between airport services and users. Effective supervision of these areas is essential to ensure safety, comfort, and order within the airport environment. A qualitative descriptive approach was employed in this research, with data collected through field observations, in-depth interviews with TIS personnel and related stakeholders, as well as documentation analysis of existing regulations and supervision procedures.The findings reveal that the TIS Unit plays a strategic role in maintaining service quality and the security of landside facilities. This role is carried out through regular monitoring activities, early detection of potential disruptions, and the handling of various violations in public areas. However, the implementation of TIS duties still faces several challenges. These include limited personnel, which restricts comprehensive supervision of all areas; slow response from relevant units when operational issues are reported; and low discipline and compliance among service users, which further complicates enforcement efforts.To enhance the effectiveness of supervision, this study proposes several recommendations. These include strengthening inter-unit coordination within the airport, providing ongoing training for TIS personnel to improve competency and responsiveness, and implementing an integrated digital reporting system to streamline reporting and follow-up processes. Such measures are expected to support more optimal and sustainable supervision of landside facilities at the airport.

Abstract

The Cargo oil pump is one of the auxiliary units on board a ship, used to transfer cargo from one location to another during loading and unloading operations. On the MT Pangrango vessel, an issue occurred with the cargo oil pump: its performance declined, resulting in slow suction during the unloading process. This problem hindered efficient cargo operations, as the pump was not functioning properly.This study aims to identify the contributing factors, impacts, and countermeasures for the decreased performance of the cargo oil pump. The research methodology applied in this thesis involved a descriptive approach combined with Miles and Huberman’s analytical method, with data validity tested via triangulation. Data collection techniques used to identify the problem included observation, interviews, documentation, and literature review.The results revealed that the pump’s shaft was worn due to excessive friction, and the ball bearing s exhibited wear and disintegration caused by lack of lubrication (grease). The recommended corrective actions were to add material to the shaft , perform realignment to correct any shaft misalignment, and implement routine maintenance—specifically, monthly grease lubrication. These measures, when properly applied, can significantly reduce the risk of Cargo oil pump damage.

Abstract

The rapid pace of urbanization has intensified competition among businesses, prompting the adoption of innovative strategies to enhance sales performance and customer engagement. PT Inspirasi Bisnis Nusantara, under the HAUS! brand, introduced “Huling,” a hyperlocal distribution service utilizing electric bikes (e-bikes) equipped with integrated storage boxes to improve delivery efficiency and environmental sustainability. This study aims to evaluate customer acceptance of the Huling service by applying the Technology Acceptance Model (TAM). The model incorporates five core variables: Perceived Ease of Use (PEOU), Perceived Usefulness (PU), Attitude Towards Usage (ATU), Behavioral Intention (BI), and Actual Usage (AU). A quantitative research approach was employed, collecting data from 258 respondents through structured questionnaires. The data were analyzed using the Partial Least Squares Structural Equation Modeling (PLS-SEM) method to assess the relationships among the TAM variables. The findings reveal that PEOU has a significant positive effect on both PU and ATU, indicating that ease of use not only improves perceptions of usefulness but also fosters favorable attitudes toward adoption. PU significantly influences ATU and BI, suggesting that perceived benefits drive both positive attitudes and intentions to use the service. Furthermore, BI has a direct and significant effect on AU, confirming that stronger behavioral intentions translate into actual utilization. The analysis highlights the strongest impact along the pathway PEOU → ATU → BI → AU, underscoring the critical role of user-friendly design and positive attitudes in driving customer adoption. This research contributes to the literature by demonstrating the applicability of TAM in the hyperlocal distribution sector, offering practical implications for service providers seeking to enhance user acceptance through improved usability and perceived value. The findings suggest that optimizing ease of use and communicating tangible benefits can significantly increase customer engagement and sustained usage of innovative delivery services.

Abstract

This study aims to analyze the factors influencing passenger satisfaction at airports through three main perspectives: service, technology, and operations. The background of this research is based on the increasing competition between airports in providing an optimal travel experience amidst the development of the aviation industry and the increasing passenger demands for service quality. This study uses a literature study approach by analyzing ten selected scientific journals that specifically discuss airport service quality from various perspectives. The results of the study indicate that the service perspective, specifically those encompassing SERVQUAL dimensions such as reliability, responsiveness, empathy, assurance, and tangibles, has a significant contribution in shaping the perception and satisfaction of airport service users. The technology perspective also plays a significant role, particularly through the implementation of self-services such as self-check-in, Flight Information Display Sistem (FIDS), e-gates, and digital service applications that simplify the travel process. One of the studies analyzed shows that the application of technology can contribute up to 96.8% to user satisfaction, indicating the significant role of digitalization in this industry. From the operational side, factors such as speed of service at the check-in counter, queue time management, completeness and cleanliness of public facilities, and ease of access to the terminal have an equally important influence. These findings underscore that passenger satisfaction is influenced not only by service quality at the point of direct interaction, but also by the smoothness of the overall operational flow. The study's conclusions emphasize the importance of integrating these three perspectives in strategic planning for airport service improvement.
