Abstract

This study examines the comparison of PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) in time management for construction projects through a case study of a 21-story high-rise building project in Yogyakarta. The research is motivated by the need for effective time management in construction projects to avoid delays that may escalate costs and disrupt project execution. The objectives are to determine the estimated duration for completing the building’s structural work, compare the differences between the initial schedule and the results of PERT and CPM analyses. The study employs a case study approach, with primary data collected through direct interviews with project stakeholders regarding activity durations and predecessors, as well as secondary data from project documentation, including schedules and structural drawings. Data analysis involves applying PERT calculations using three-time estimates (optimistic, most likely, and pessimistic) and identifying critical paths through CPM. Data processing and network diagram visualization are conducted using a project management software to comprehensively map critical and non-critical project activities.  Results indicate that the CPM method predicts a project duration of 419 days, 237 days shorter than the initial schedule, while the PERT method estimates 580 days, 76 days shorter than the original timeline, with an 82.98% probability of timely completion.

Abstract

This study investigates the use of T-shaped thermal blocks composed of fine-grained concrete and basalt slabs to enhance the energy efficiency of frame buildings. Although frame structures are widely used in modern construction for their economic and structural advantages, improving the thermal performance of their external walls remains a critical challenge. This research addresses the knowledge gap by analyzing the structural composition, thermal resistance, and condensation prevention properties of multilayer thermal blocks. A combination of experimental assessment and numerical heat transfer modeling was conducted under the climatic conditions of Samarkand using SmartCalc ThermoCalc. The results demonstrate that the use of basalt insulation and thin adhesive joints significantly reduces thermal bridges and enhances heat retention. The calculated heat transfer resistance of the wall sections exceeded the required norm (Ro ≥ 2.2 m²·°C/W), and simulations showed no condensation on the inner surface even at -15°C, ensuring indoor comfort. These findings imply that T-shaped thermal blocks are an effective, locally sourced solution for sustainable and thermally resilient construction. This has practical implications for reducing energy consumption, operational costs, and environmental impact in cold climates

Abstract

This study examines the evolving role of Iranian university technoparks in promoting sustainable development through green technologies and innovations. The research identifies a gap in the global understanding of how academic institutions in the Middle East contribute to climate and environmental challenges. Using qualitative content analysis of national initiatives, university programs, and technology transfer mechanisms, the study highlights key methods by which technoparks foster environmentally friendly solutions. Examples include solar energy innovations at the University of Tehran, hydrogen fuel cell development at IUST, and plastic waste recycling at AUT. Technoparks not only serve as incubators for startups and cleantech solutions but also act as platforms for knowledge-based companies to collaborate with industry and government. Findings reveal that technoparks provide critical infrastructure for R&D, facilitate commercialization of academic research, and promote sustainable entrepreneurship through training, incentives, and public-private partnerships. These institutions also support national climate goals, including emission reductions and water conservation strategies. The results show that despite ecological startups constituting a small percentage of Iran’s knowledge-based firms as of 2018, recent policy shifts (2022–2025) are catalyzing growth in the green tech sector. The implications suggest that university technoparks are central to transforming Iran’s innovation ecosystem toward sustainability and represent scalable models for similar contexts globally. Further research is encouraged to quantitatively assess the long-term impact of such technoparks on regional development and climate resilience.

Abstract

The reconstruction of the Public Housing Project by the Government of Surakarta was initiated in response to structural failure in the previous building. Design modifications during the construction process—particularly in the beam elements—necessitated a reassessment of structural safety. This study aims to evaluate the safety of beams based on the Indonesian National Standard (SNI) 1727:2020, which regulates minimum load requirements for buildings. A quantitative descriptive method was employed using secondary data obtained from project documentation. The analysis focused on beam B45 as a representative sample, considering dead loads, live loads, and their respective combinations. The results indicate that the nominal moment capacity (Mn) of 326.72 kNm exceeds the ultimate moment (Mu) of 219.15 kNm, confirming that the beam is structurally safe under actual service loads. These findings underscore the importance of conducting technical evaluations for every design alteration to ensure continued compliance with safety standards.

Abstract

This study aims to analyze the effect of the CARTRACK application on the productivity and operational efficiency of heavy equipment in the IKN 3A Toll Road Project, Karangjoang–KKT Kariangau segment. CARTRACK is a GPS-based telematics system that records real-time data on equipment operation, including effective working hours, idle time, and work volume. A comparative quantitative method was used by evaluating data obtained from two monitoring methods: manual recording using Daily Time Sheets and digital tracking through CARTRACK. Six types of heavy equipment were observed: Excavator, Dump Truck, Truck Mixer, Truck Trailer, Vibratory Soil Compactor, and Crane. Data were processed using productivity and efficiency formulas and analyzed using linear regression. The results indicate that the use of CARTRACK significantly improves both productivity and efficiency. The Dump Truck showed an increase in productivity from 2.05 m³/hour to 2.98 m³/hour, while the Crane recorded the highest efficiency gain at 41%. Regression analysis demonstrated a strong positive relationship between effective working hours and productivity, with the highest coefficient of determination (R² = 0.5895) and correlation coefficient (R = 0.7678) for the Dump Truck. These findings confirm that CARTRACK enhances monitoring accuracy and contributes to more efficient and productive heavy equipment operations in large-scale infrastructure projects

Abstract

Limbah cair merupakan salah satu penyebab utama pencemaran lingkungan yang dapat mengancam ekosistem, sehingga diperlukan proses pengolahan yang efektif untuk mengurangi dampaknya. Berbagai upaya pengendalian telah dilakukan, dan salah satu alternatif teknologi terbaru adalah penambahan bakteri probiotik ke dalam proses pengolahan. Bakteri probiotik terbukti memiliki kemampuan menurunkan kadar parameter kualitas air limbah, yaitu BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), dan TSS (Total Suspended Solids). Berdasarkan hasil telaah, ditemukan tiga jenis probiotik yang paling banyak digunakan, yaitu Lactobacillus, Bacillus, dan kombinasi keduanya. Penelitian ini bertujuan untuk mengolah data dan menguji apakah penurunan nilai parameter BOD, COD, dan TSS setelah penambahan bakteri probiotik signifikan secara statistik, mengklasifikasikan persentase penurunan nilai tersebut ke dalam kategori rendah, sedang, dan tinggi, serta menguji perbedaan signifikan dalam penurunan parameter antara ketiga jenis bakteri secara statistik. Metode yang digunakan adalah pengolahan data sekunder yang diperoleh dari jurnal-jurnal relevan, kemudian diproses menggunakan IBM SPSS Statistics. Analisis dilakukan melalui statistik deskriptif, uji normalitas, dan ANOVA. Hasil penelitian menunjukkan bahwa: (1) penambahan bakteri probiotik berhasil menurunkan kadar BOD, COD, dan TSS secara signifikan berdasarkan uji Wilcoxon Rank-Test (p < 0,05), dengan BOD turun dari 2.100 mg/L menjadi 70 mg/L dan COD dari 132 mg/L menjadi 38,1 mg/L. (2) Distribusi nilai persentase penurunan menunjukkan bahwa mayoritas data untuk ketiga parameter (BOD, COD, dan TSS) berada pada kategori sedang, yang mencerminkan efektivitas pengolahan yang baik secara umum. Namun, beberapa data di kategori rendah menunjukkan perlunya optimalisasi, sementara kategori tinggi menunjukkan potensi hasil optimal. (3) Hasil uji ANOVA menunjukkan tidak ada perbedaan signifikan antar jenis bakteri (Lactobacillus, Bacillus, dan kombinasi keduanya) terhadap penurunan BOD, COD, dan TSS (p > 0,05), yang mengindikasikan bahwa pemilihan jenis bakteri tidak mempengaruhi efektivitas, sehingga fokus sebaiknya diarahkan pada pengelolaan proses pengolahan limbah cair.

Abstract

This research investigates an alternative structural design for the approach bridge of a pedestrian suspension bridge by replacing reinforced concrete with structural steel to address construction challenges in remote areas. The study focuses on the Lobang Baru Pedestrian Suspension Bridge in Banjar Regency, South Kalimantan, where the Kulur Tengah side faces significant logistical constraints including limited accessibility, frequent river flooding, and inadequate transportation infrastructure for concrete materials. Using finite element modeling analysis, two structural systems were comprehensively evaluated: the existing reinforced concrete design and a proposed steel-based alternative. The steel alternative design employs H-shaped steel sections for main girders (H350x350-12/19), diaphragms (H200x200-8/12), and cross girders (H300x300-10/15), with hollow structural sections (HSS 508x9.5) for columns and 8mm steel deck plates. Results demonstrate substantial improvements: total structural weight decreased by 72.2% from 55.92 tons to 15.55 tons, with the weight per unit length reduced from 3.43 ton/m to 0.65 ton/m. The steel design eliminated 23.79 m³ of concrete from the superstructure while requiring only a single support at the pillar block instead of dual supports at both pillar and anchor blocks, thereby reducing structural complexity and foundation loads. Although substructure concrete volume increased by 27.12 m³ due to the separate abutment construction, the overall design significantly improves constructability through prefabrication, modular assembly, and reduced vulnerability to environmental conditions. These findings validate the technical and practical feasibility of steel-based approach structures for pedestrian suspension bridges in challenging rural environments, offering a replicable solution for similar infrastructure projects across Indonesia and other developing regions facing comparable geographic and climatic constraints.

Abstract

This study investigates the use of the Morlife 300 anti-stripping agent to improve the performance of Asphalt Concrete–Wearing Course (AC-WC) mixtures incorporating local aggregates from Madura Island, Indonesia. The objective of this research is to determine the Marshall characteristics of the mixture and to identify both the optimum asphalt content and the optimum anti-stripping dosage based on the 2018 Bina Marga Specifications (Revision 2). Laboratory testing was conducted using asphalt contents of 5%, 6%, and 7%, resulting in an optimum asphalt content of 5.2%, while additive variations of 0%, 0.1%, 0.3%, and 0.5% were used for performance evaluation. The results show that the incorporation of Morlife 300 enhances mixture performance, as indicated by decreasing Air Voids and Voids in Mineral Aggregate and increasing Voids Filled with Asphalt, along with improved stability and Marshall Quotient values. Compared to the mixture without additive, the use of  0.3% Morlife 300 increases stability by 30.57% and the Marshall Quotient by 29.38%, marking this dosage as the optimum level among all variations tested. Overall, the use of the Morlife 300 anti-stripping agent is proven to improve the volumetric and mechanical performance of AC-WC mixtures.
