Abstract

The construction industry, particularly in housing development, plays a strategic role in meeting the need for adequate housing, supporting economic growth, and improving the quality of life for communities. However, the implementation of housing projects faces complex challenges, such as pressure to meet high quality standards, tight schedules, and limited budgets. Factors such as communication aspects and leadership competence play a significant role in decision-making to enhance project performance. This study aims to analyze various factors that influence the quality and performance of projects in housing development, including the influence of communication and leadership competence in decision-making to improve project performance. In addition, this research also evaluates the relationship between decision-making and project performance, as well as the mediating role of decision-making in the relationship between communication aspects and leadership competence on project performance. This study uses a quantitative approach with a survey method. Data were collected through a closed-ended questionnaire using a Likert scale and analyzed using statistics. The analysis includes descriptive analysis and PLS-SEM (Partial Least Squares Structural Equation Modeling), covering both the outer model and inner model measurements. The results of this study revealed a significant relationship between communication aspects and project leadership competencies on decision-making, as well as the impact of decision-making on overall project performance with a percentage of 73.6%. Furthermore, decision-making plays an important mediator in strengthening the relationship between the two variables of communication aspects and project leadership competencies with project performance with a percentage of 49.4%.

Abstract

The redesign of the Tiu Spara Dam main dam was carried out in response to changes in technical conditions and operational needs of the project, but this process has the potential to pose various risks that can affect the stability, safety, and performance of the dam. This study aims to identify risk indicators, analyze risk levels and priorities, and formulate risk control strategies in the redesign of the Tiu Suntuk Dam main dam. The method used is a descriptive quantitative approach based on ISO 31000:2018 risk management, with data collection through field observations, interviews, literature studies, and questionnaire dissemination to experienced respondents. Risk analysis was conducted using the Severity Index method to assess the probability and impact of the risk, which was subsequently mapped into a risk matrix. The results showed that the highest risk came from the technical aspects, namely changes in soil carrying capacity, availability of materials for new designs, and suitability of dam design with actual slope conditions, all of which fall under the category of extreme risk. Therefore, it is necessary to strengthen technical investigations, design adjustments, improve work quality control, and implement systematic and integrated risk management. This research is expected to be a reference in risk management in similar dam projects to improve structural safety and the sustainability of dam functions.

Abstract

Simpang Ayam Village is located in Bengkalis District, Bengkalis Regency, Riau Province. This coastal area consists of peatland and faces the Malacca Strait, making it vulnerable to wave-induced abrasion. At the end of 2022, a significant landslide occurred in Simpang Ayam Village, causing substantial shoreline changes and resulting in the loss of dozens of hectares of land to the sea. Conducting manual investigations in the landslide-affected area is not feasible due to continuous land movement towards the sea, posing serious safety risks. Remote sensing technology offers an effective method to analyze shoreline changes using the Modified Normalized Difference Water Index (MNDWI) and vegetation density changes through the Normalized Difference Vegetation Index (NDVI). This study utilizes Sentinel-2 medium-resolution satellite imagery to assess these changes. The results indicate a noticeable shift in the shoreline, marked by landward advancement, and a decline in vegetation density, as evidenced by a vegetation index decrease of more than -0.1. Furthermore, the total landslide-affected area was 36.89 hectares, with the largest landslide occurring at Location 3 (15.96 hectares) and the smallest at Location 9 (0.49 hectares).

Abstract

The coastal area of ​​North Jakarta faces significant pressure due to land subsidence, sea level rise, and complex hydrodynamics. These conditions increase the risk of failure of coastal protection structures, especially in retaining walls with corrugated concrete sheet piles (CCSP). This study aims to analyze risk management in the redesign of the coastal protection tie-back system at the Cengkareng Drain site, DKI Jakarta. The research method combines qualitative and quantitative approaches through field observations, document studies, expert interviews, and risk analysis using Failure Mode and Effect Analysis (FMEA) and Analytic Hierarchy Process (AHP). The analysis results indicate that technical risks in the form of slope instability and lateral deformation of the CCSP are prioritized risks with a very high category. The application of the tie-back system in the redesign was able to reduce lateral deformation from 59.6 cm to 37.1 cm and increase the safety factor to 1.521. This study confirms that an integrated risk management approach is effective in supporting decision-making for more reliable and sustainable coastal protection structure redesign.

Abstract

The accelerating development of Artificial Intelligence (AI) and automation technologies has profoundly transformed the digital business ecosystem, catalyzing the emergence of cyberpreneurship as a dominant model of contemporary entrepreneurship. While AI enables unprecedented opportunities such as enhanced decision making, operational efficiency, personalized customer experience, and scalable business growth it simultaneously introduces critical challenges, including data privacy risks, algorithmic bias, digital inequality, and workforce displacement. This study systematically synthesizes existing research to examine the dualistic impact of AI and automation on cyberpreneurial opportunities and challenges. Employing a Systematic Literature Review (SLR) integrated with Bibliometric Analysis, 525 articles published between 2018 and 2025 were collected from Scopus and Web of Science. Bibliometric mapping using VOSviewer identified five core thematic clusters, technological innovation, business efficiency, digital transformation, startup ecosystems, and AI-driven marketing. The results highlight that AI-driven automation significantly enhances cyberpreneurial innovation and competitiveness, yet its adoption remains uneven due to technical, ethical, and socio economic constraints. This study concludes that future research should prioritize the development of adaptive, human centric frameworks that balance automation benefits with ethical considerations to ensure sustainable and inclusive cyberpreneurial growth in the AI-driven digital economy.

Abstract

Tidung Island, a major tourist destination in the Thousand Islands, faces coastal erosion caused by wave energy, tidal currents, and anthropogenic activities, which threaten coastal ecosystems, marine tourism quality, and residential areas. Coastal protection measures have been implemented through wave protection structures. However, their performance has been suboptimal due to limited maintenance, design incompatibility with local hydro-oceanographic conditions, and the absence of a systematic approach for selecting breakwater types. This study aims to identify the criteria and sub-criteria influencing breakwater selection and determine the most suitable structure for Tidung Island using the Analytic Hierarchy Process (AHP). The AHP model integrates technical, environmental, socio-economic, field condition, and construction method aspects, based on secondary hydro-oceanographic data (tides, wind, wave height, and effective fetch) and expert judgments through pairwise comparisons. The results show that technical aspects have the highest priority (0.312), followed by environmental aspects (0.268), field conditions (0.201), socio-economic factors (0.127), and implementation methods (0.092), with all consistency ratio values below 0.10. The selected structure is a hollow cube breakwater with a filter-coated rockfill foundation, as it provides an optimal balance between technical performance, cost efficiency, ease of implementation in shallow waters, and manageable environmental impacts. This AHP-based model can support sustainable coastal protection decision-making.

Abstract

Urban drainage projects play a strategic role in controlling runoff and mitigating flooding. However, construction quality issues often arise during implementation, leading to channel failure. This study aims to analyze the impact of implementing the ISO 9001:2015 Quality Management System on the quality of drainage projects using the Failure Mode and Effect Analysis (FMEA) approach, through a case study of the Rasuna Said drainage channel in Kuningan, Jakarta. The research methodology combines primary and secondary data obtained through field observations, interviews, questionnaires based on ISO 9001:2015 clauses, and project document analysis. Quality risk identification is conducted using the FMEA method, with severity, occurrence, and detectability parameters assessed to determine the Risk Priority Number (RPN). The results show that the main failure modes with the highest risk levels include mismatched channel elevation and slope, loosely fitting channel element connections, uneven subgrade compaction, and initial sedimentation due to weak work environment controls. These risks are generally related to the field operational stage and the suboptimal application of the risk based thinking principle in ISO 9001:2015. The integration of the FMEA method with ISO 9001:2015 has been proven to identify and prioritize quality risks more systematically and support the development of measurable mitigation actions. This study concludes that the implementation of ISO 9001:2015, integrated with FMEA, can improve the effectiveness of quality control, minimize the risk of construction failure, and support the sustainability of urban drainage projects.

Abstract

Dalam beberapa dekade terakhir, wilayah Daerah Aliran Sungai (DAS) Juwana di Jawa Tengah semakin sering dilanda banjir sehingga berdampak serius, mulai dari kerugian ekonomi hingga gangguan kesehatan pada masyarakat. Perubahan penggunaan lahan dan pengaruh perubahan iklim global diyakini menjadi pemicu utama perubahan pola curah hujan di wilayah ini. Penelitian ini dilakukan untuk memahami bagaimana dinamika curah hujan berkembang di DAS Juwana selama 22 tahun terakhir (1998–2019), serta bagaimana kondisi ini mungkin berubah hingga tahun 2080 berdasarkan dua skenario iklim yaitu pada kondisi RCP 4.5 dan RCP 8.5. Kami menggunakan metode downscaling statistik dengan data curah hujan satelit TRMM yang dikombinasikan dengan model iklim global CMIP5. Hasilnya menunjukkan bahwa DAS Juwana memiliki pola hujan tropis, dengan puncak curah hujan terjadi pada Desember hingga Februari. Beberapa tahun seperti 2006, 2008, dan 2010 mencatat hujan ekstrem yang bertepatan dengan fenomena La Niña. Proyeksi ke depan menunjukkan adanya tren peningkatan intensitas curah hujan, khususnya pada musim hujan. Di bawah skenario RCP 8.5, lonjakan curah hujan lebih tajam dibandingkan RCP 4.5, terutama pada Januari dan Desember. Temuan ini menjadi peringatan penting akan meningkatnya risiko banjir ekstrem di masa depan dan menegaskan perlunya strategi adaptasi serta perencanaan pengelolaan air yang lebih tanggap terhadap perubahan iklim masa depan.

Abstract

Abstract   As consumers and businesses rely on the efficiency, safety, and reliability of transportation networks, the quality of urban life is at risk due to increasing traffic congestion. The current study aims to evaluate the capacity of an intersection by recalculating the existing condition and making changes with geometric improvements, namely symmetrizing the intersection arms and traffic separation islands and widening the intersection arms. Factors that affect traffic congestion at intersections in the Banda Aceh area, such as driver behavior, traffic light capacity, peak-hour drivers, and intersection design. This study compares on-site data with the performance of signalized intersections using various traffic methodologies. With a population of 261,000 in Banda Aceh, Simpang Surabaya is known as a busy route in urban life. Two techniques are used for the analysis: applying the Indonesian Highway Capacity Manual (MJKI) to the road widening and geometric re-planning. The results show that the intersection capacity is close to saturation, with a saturation value of 1.336 which exceeds 0.85 due to asymmetric traffic islands, high volumes, and long cycle times. Geometric changes and wider intersection roads reduce this value to 0.83. The results indicate that Simpang Surabaya (the intersection of Surabaya) needs to be widened immediately and properly. Further research is recommended to evaluate other intersections in the city of Aceh with quite busy traffic density to carry out calculations and handling by using different of MJKI accordingly.   Keywords: Traffic volume; signalized intersection, capacity; degree of saturation; traffic delay   Abstrak   Ketika konsumen dan perusahaan bergantung pada efisiensi, keamanan, dan keandalan jaringan transportasi, kualitas kehidupan perkotaan berada dalam risiko akibat meningkatnya kemacetan lalu lintas. Penelitian saat ini bertujuan untuk mengevaluasi kapasitas persimpangan dengan menghitung ulang kondisi eksisting dan melakukan perubahan dengan perbaikan geometrik yaitu mensimetriskan lengan-lengan simpang dan pulau pemisah arus lalu lintas dan pelebaran lengan simpang. Faktor -faktor yang mempengaruhi kemacetan lalu lintas di persimpangan jalan di daerah Banda Aceh, seperti perilaku pengemudi, kapasitas lampu lalu lintas, pengemudi pada jam sibuk, dan desain persimpangan. Studi ini membandingkan data di lokasi dengan kinerja persimpangan yang dilengkapi sinyal menggunakan berbagai metodologi lalu lintas. Dengan 261.000 penduduk, Simpang Surabaya di Banda Aceh dikenal sebagai jalur sibuk dalam kehidupan perkotaan. Dua teknik digunakan untuk analisis: menerapkan manual kapasitas jalan raya Indonesia (MJKI) pada pelebaran jalan dan perencanaan geometrik ulang. Hasilnya menunjukkan bahwa kapasitas persimpangan mendekati jenuh, dengan nilai jenuh sebesar 1,336 yang melebihi 0,85 akibat pulau lalu lintas yang asimetris, volume tinggi, dan waktu siklus yang panjang. Perubahan geometris dan jalan persimpangan yang lebih lebar mengurangi nilai ini menjadi 0,83. Hasilnya menunjukkan bahwa Simpang Surabaya perlu segera diperlebar dengan baik. Penelitian selanjutnya dianjurkan mengevaluasi simpang dengan kepadatan yang cukup sibuk di daerah Aceh lainnya untuk dilakukan kalkulasi dan penanganan secepatnya.   Kata kunci: Volume lalulintas, simpang bersinyal, kapasitas, derajat kejenuhan, tundaan lalu   lintas
