Abstract

The utilization phase of Green Building (BGH) plays an important role in ensuring the sustainability of building performance through effective control of energy consumption, water efficiency, and operational management. RSUD Tanjung Redeb, Berau Regency, as a healthcare facility operating 24 hours a day, has a high level of energy and resource consumption, requiring an operational management strategy based on green building principles. This study aims to analyze the operational performance of Green Building implementation during the utilization phase at RSUD Tanjung Redeb and evaluate the potential for energy efficiency, water conservation, and green building certification achievement. The research method used is descriptive qualitative with a technical analysis approach through observation of mechanical, electrical, and plumbing (MEP) systems, interviews with facility management personnel, and review of supporting documents such as utility logbooks, maintenance standard operating procedures, and green building assessment regulations based on the Minister of Public Works and Housing Regulation No. 21 of 2021 and the Ministerial Circular Letter No. 01/SE/M/2022. The analysis was conducted using Energy Consumption Intensity (IKE), water efficiency performance, and Green Building assessment score accumulation parameters. The results indicate that the implementation of high-efficiency chillers, LED lighting systems equipped with occupancy sensors, greywater recycling systems, and rainwater harvesting technology can improve operational efficiency at RSUD Tanjung Redeb. The building is projected to achieve an IKE value of 280.78 kWh/m²/year, representing an energy efficiency improvement of 26.11% compared with the standard limit for hospital buildings. Furthermore, water conservation strategies are projected to reduce water consumption by 26.92% compared with the baseline condition. From the financial perspective, the implementation of Green Building strategies provides potential operational cost savings of approximately IDR 2.55 billion per year with an estimated investment payback period of 5–7 years. Based on the performance assessment model, the operational achievement score is projected at 73.04%, indicating the potential to meet the criteria for a “Madya” level Green Building certification. This study demonstrates that optimizing the utilization phase is a key factor in maintaining green building performance while supporting cost efficiency, resource conservation, and sustainable healthcare facility development.

Abstract

Derawan Island is one of the leading tourism destinations in Berau Regency that is vulnerable to coastal erosion, particularly along the eastern to northeastern parts of the island. Continuous coastal erosion poses a significant threat to tourism areas, local settlements, and coastal infrastructure located along the shoreline. This study aims to analyze the coastal erosion conditions and determine the most appropriate coastal protection structure as a mitigation measure to reduce erosion and protect the tourism area of Derawan Island. The research employed shoreline change analysis using the Digital Shoreline Analysis System (DSAS), hydro-oceanographic condition analysis, coastal erosion vulnerability and risk assessment, and evaluation of alternative coastal protection structures based on technical and environmental criteria. The results indicate that the eastern to northeastern coast of Derawan Island has experienced coastal erosion covering approximately 1.4 ha, with a shoreline change rate of -1.71 m/year. Hydro-oceanographic analysis shows that waves and ocean currents play a significant role in sediment transport processes, thereby influencing shoreline dynamics. Based on the evaluation of alternative coastal protection structures, an offshore breakwater was identified as the most suitable option due to its superior ability to reduce wave energy, control coastal erosion, and accommodate environmental considerations while maintaining tourism activities. The proposed coastal protection concept consists of a series of offshore breakwaters connected by a causeway, strategically located in areas experiencing the most severe erosion. The findings of this study are expected to provide a scientific basis for coastal protection planning and contribute to the sustainable management of the coastal tourism area of Derawan Island.

Abstract

Material distribution is one of the important factors affecting the successful implementation of road construction projects. Delays in material distribution can disrupt construction activities, reduce the productivity of labor and equipment, and potentially increase project costs and completion time. This study aims to analyze the impact of material distribution delays on time and cost performance in the Kasai–Semanting Road Construction Project, Berau Regency. The research method was conducted through the collection of primary and secondary data, including work volume data, material requirements, construction schedules, and project implementation data. The analysis was carried out by identifying the dominant materials used in the project, calculating material requirements, and simulating the effect of material distribution delays on effective daily working hours. The results indicate that delays in material distribution cause a reduction in effective working hours, which directly affects labor and equipment productivity, resulting in decreased daily work output and longer project completion time compared to the initial schedule. Material distribution delays also have the potential to increase project costs due to extended resource utilization duration and reduced construction efficiency. Under significant delay conditions, the project completion duration may experience delays of up to 90 days beyond the planned schedule. Based on the findings, it can be concluded that effective material distribution management plays an important role in maintaining project cost and time performance. Therefore, proper material planning, distribution management, and adequate monitoring systems are required to minimize the risk of construction project delays.

Abstract

Derawan Island District is an archipelagic area with continuously developing marine tourism potential; however, its road infrastructure faces technical challenges due to coastal subgrade characteristics, water inundation, and increasing tourism-related traffic loads. This study aims to design an appropriate pavement structure to support road reconstruction in the area by comparing two design alternatives, namely flexible pavement and rigid pavement. The method employed includes a review of secondary data consisting of soil characteristics, traffic volume, and climatic conditions, which were subsequently analyzed using the Indonesian Highway Design Manual (Bina Marga) pavement thickness design guidelines and the AASHTO 1993 design references. The results indicate that rigid pavement is technically more suitable for road sections with low soil bearing capacity and high inundation risks, while flexible pavement remains applicable for segments with more stable soil conditions and faster construction requirements. This study is expected to serve as an initial technical reference for planners and stakeholders in determining effective, durable, and geographically appropriate road reconstruction strategies for small archipelagic regions.

Abstract

The Labanan–Tepian Buah Main Road is one of the strategic road segments in Berau Regency that plays an important role in supporting community mobility and the distribution of goods and services. Along with increasing traffic loads and the demand for better road services, a pavement structure with higher durability and longer service life is required. This study aims to analyze the implementation of a design review from flexible pavement to rigid pavement for the reconstruction project of the Labanan–Tepian Buah Main Road in Berau Regency. The research method was conducted through a design review analysis of the initial pavement design, evaluation of alternative pavement structures, and comparison of construction costs and implementation duration between the two pavement types. The results show that the application of rigid pavement provides improved structural performance and a longer service life compared to flexible pavement. In terms of construction costs, flexible pavement requires a cost of IDR 3,128,558,000, while rigid pavement requires IDR 8,565,765,765. Regarding construction duration, flexible pavement requires approximately 8 working days, whereas rigid pavement requires around 20 working days. Although rigid pavement requires higher initial costs and longer construction time, it is considered more suitable for roads with high traffic loads due to its better structural durability, lower maintenance requirements, and improved efficiency in road management throughout its service life. The results indicate that the design review process can serve as an effective approach for determining more sustainable and efficient pavement alternatives in road infrastructure development.

Abstract

Sleman Regency has a high population density, requiring adequate transportation facilities to prevent traffic congestion and excessive fuel consumption. One of the intersections that frequently experiences long vehicle queues during peak hours is located at Jl. Wates Km 5, west of Gamping Market. This study aims to evaluate the performance of the intersection and propose appropriate improvement measures. The research method refers to the Indonesian Highway Capacity Manual (MKJI) 1997. Primary data were collected through field surveys conducted over three days (Monday, Wednesday, and Saturday) during morning, midday, and evening peak hours, while secondary data on population were obtained from relevant government agencies. The analysis of the existing condition indicates a degree of saturation (DS) of 1.249, which exceeds the recommended limit specified in MKJI 1997 (DS < 0.80). To address this problem, two improvement alternatives were evaluated. The first alternative involved installing a median barrier and reducing roadside friction from a medium to a very low level, resulting in a reduction of the DS to 0.921. The second alternative combined the first measure with a 2.5-meter widening of the minor-road approach, further reducing the DS to 0.894 and decreasing the average intersection delay to 15.236 seconds. Although the final degree of saturation remains above the ideal threshold of 0.80, both alternatives significantly improve traffic flow by reducing congestion and vehicle delay at the intersection.

Abstract

Construction projects often encounter challenges that influence schedule, cost, and quality performance. One significant issue is material distribution delay, which may occur due to logistical problems, supplier dependency, and inadequate material management. Such delays can reduce productivity, extend project duration, and increase costs because of additional resource utilization. This study aims to analyze the impact of material distribution delays on time and cost performance in the Road Area Improvement Project of Jl. Manunggal Jaya Provincial Road Section Kampung Kayu Indah (HTI) by PT. Wana Kaltim Lestari in Berau Regency. The research method involved primary and secondary data collection, including work volume, material requirements, project schedules, and implementation data. Analysis was conducted by identifying dominant materials, calculating requirements, and simulating the effect of distribution delays on effective working hours. The results show that delays in material distribution decrease effective working hours, reducing labor and equipment productivity. Consequently, daily work output decreases and project completion becomes longer than planned. Significant delays may extend project duration up to 90 days and increase costs due to prolonged resource use. Effective material distribution management is therefore essential to maintain project performance and minimize delay risks through proper planning, monitoring, and control systems during construction activities.

Abstract

This study investigates the marketing communication strategies employed by Airy School in establishing its brand image as a specialized provider of school documentation services in Pasuruan. In a crowded creative industry dominated by general retail photography, many local educational institutions lack standardized, high-quality visual documentation due to fragmented project execution and limited market awareness. Building a clear specialized brand identity is therefore critical to earning institutional trust within bureaucratic school environments. Using a qualitative descriptive approach, data were gathered through in-depth interviews with Airy School's owner, marketing personnel, operational staff, and school clients, supplemented by field observations and document analysis. The analytical framework integrates Kotler and Keller's Marketing Communication Mix with Keller's Customer-Based Brand Equity (CBBE) model. The findings reveal that Airy School effectively executes an Integrated Marketing Communications (IMC) strategy, with personal selling serving as the most dominant and decisive channel to navigate school bureaucracies. Educational presentation tactics, value-driven all-in-one project structures, and interactive digital marketing successfully demonstrate perceived quality and operational reliability. Consequently, this approach constructs strong, favorable, and unique brand associations across the brand attribute, benefit, and attitude dimensions of the CBBE pyramid. This research underscores the importance of service specialization and consultative communication in transforming routine educational documentation into a strategic visual branding asset, offering a practical model for creative agencies operating in business-to-business regional markets.
