Abstract

This study explores how lecturers across five departments at Narotama University—Early Childhood Education (PG PAUD), Civil Engineering, Economics and Business, Computer Science, and Law—interpret and apply andragogical principles within project-based learning (PjBL). Using a qualitative phenomenological design, data were collected through semi-structured interviews with five purposively selected lecturers who had at least two semesters of PjBL experience. Thematic analysis revealed four major themes: (1) the shifting role of lecturers from information transmitters to facilitators; (2) increased student autonomy and engagement; (3) challenges related to students’ readiness for self-directed learning; and (4) the role of reflection in lecturers’ professional growth. The findings indicate that while andragogy aligns strongly with PjBL, its implementation is highly contextual, requiring adaptations based on disciplinary demands and student characteristics. This study contributes to the discourse on contextualized andragogical practice in higher education, highlighting implications for lecturer training, curriculum design, and institutional policy.

Abstract

Rapid motorization in Indonesia has intensified congestion not only in metropolitan areas but also in secondary urban centers such as Genteng District, Banyuwangi, where a single arterial corridor supports commercial and inter-district mobility. However, research addressing congestion mitigation in semi-urban road networks through strategic traffic diversion remains limited. This study evaluates the effectiveness of an alternative road routing strategy in reducing congestion along Jalan Gajah Mada using VISSIM-based microscopic simulation. Two scenarios were compared: the existing condition and a diversion strategy rerouting vehicles through Jalan KH Wahid Hasyim. Key performance indicators—average travel time, speed, queue length, and level of service (LoS)—were analyzed. Results reveal significant performance improvements despite a longer physical route: travel time decreased by 25.8%, speed increased by 143.6%, queue length reduced by 44.9%, and LoS improved from E to D. These findings highlight the potential of strategically planned traffic diversion to enhance mobility in semi-urban settings. The study is limited to peak-hour traffic and a single diversion scenario, suggesting the need for further evaluation with multimodal and multi-scenario analyses.

Abstract

Efficient project delivery is a critical requirement for rural road rehabilitation programs, yet empirical evaluations of implementation efficiency remain limited. This study analyzes the time and estimated cost efficiency of the Papring Hotmix Road Rehabilitation Project in Kalipuro District, Banyuwangi, using a descriptive quantitative case study approach based on weekly and monthly project documentation. Project performance was measured by comparing baseline planning with field realization, supported by calculations of time efficiency, deviation analysis, and cost implication estimation derived from work-weight distribution. The project was completed in 55 days, significantly faster than the 120-day planned duration, resulting in a time efficiency of 54.17% and a maximum positive deviation of +76.32% at completion. Major work components: AC-WC (65.616%), AC-BC (18.249%), and aggregate base layer (12.436%), were executed intensively between Weeks 4 and 7, enabling a shortened execution period that suggests potential savings in indirect project costs such as overhead, labor, and field operations. Acceleration was driven by effective technical scheduling, early resource mobilization, optimized labor deployment, and strong contractor–consultant coordination. The findings highlight the importance of structured progress evaluation for improving scheduling and cost control in rural road rehabilitation projects. Future work should incorporate financial realization data and risk-productivity modelling to strengthen efficiency assessment in accelerated infrastructure delivery.

Abstract

Assessing the insulation condition of power transformers is crucial for maintaining the reliability of electrical power systems. This research aims to predict the remaining life of the transformer at PLTU Suralaya Unit 6 by integrating the measurement of the dissipation factor (tan δ) using Dielectric Frequency Response (DFR) testing at ultra-low frequency (1 mHz = 0.001 Hz) and estimating the Degree of Polymerization (DP) through empirical correlation. The DFR measurements were performed with the OMICRON DIRANA device (frequency range 0.1 mHz–1 kHz) and validated against tan δ measurements at 50 Hz using OMICRON CPTD equipment. The dissipation factor at 1 mHz was extracted and converted to an estimated DP value through a validated regression model. Results show a DP value of approximately 302, indicating advanced degradation of the cellulose insulation. This corresponds to an estimated remaining life percentage of 29.68%, equivalent to an operational lifespan of roughly 11.87 years before reaching the end-of-life threshold. The study confirms that ultra-low-frequency DFR testing combined with DP estimation provides a non-destructive and effective approach for transformer remaining life prediction. It is recommended to implement condition-based monitoring and supplement with oil chemical analysis (e.g., furan compounds) and other diagnostic methods to enhance prediction accuracy and support proactive asset management.

Abstract

The grounding system is a crucial element in lightning protection because it channels current to the ground for the safety of buildings, equipment, and humans. This study evaluated the grounding resistance at the JoMA Boutique Villa & Resort project and assessed its effectiveness based on the SNI 03-7015-2004, IEEE Std 80-2013, and NFPA 780 standards, which stipulate a maximum limit of 5 Ω. Measurements at four electrode points using an earth tester yielded values of 2.41 Ω, 0.23 Ω, 0.11 Ω, and 0.22 Ω. All results were well below the standard, with effectiveness ranging from 207.47% to 4545.45%. Variations in values were influenced by soil conditions, where embankment soil had higher resistance than wet clay soil. Overall, the grounding system at the study site proved to be highly effective and reliable in protecting buildings and electronic equipment, as well as reducing the risk of step and touch voltages that endanger human safety.

Abstract

Livestock Gaduh is an activity that has been carried out for generations, where the Gaduh giver entrusts his livestock to be cared for by the Gaduh recipient with a profit-sharing agreement. The absence of an agreement between the 2 (two) parties by only relying on trust has caused various conflicts, one of which is the crime of embezzlement or fraud. The purpose of this study is to make Gaduh givers more careful in entrusting their livestock to be entrusted to someone (the Gaduh recipient). The method in this writing uses normative juridical with a statutory and conceptual approach. The results of this study are that many people only rely on customary law to place trust in the Gaduh giver so that when the Gaduh recipient has bad intentions to sell his livestock without the knowledge of the Gaduh giver, it cannot be processed administratively, because there is no written evidence. Therefore, criminal law as an ultimum remidium is one solution to resolve this problem

Abstract

Technological development is advancing at a very rapid pace. This progress affects various aspects of life, including the field of Islamic education. Islamic Boarding School Islamic Boarding School Mihrob Maryam Garum is an institution based on Qur’an memorization (tahfidz), which enforces very strict rules prohibiting the use of gadgets to maintain the retention of Qur’anic memorization. However, a serious challenge arises when students complete their education and return to a society that is fully digitalized. They are faced with the need to adapt to technology while preserving the values of the Islamic Boarding School amid the overwhelming flow of information. This study aims to describe the forms of adaptation of tahfidz students to the digital era through the lens of the Islamic education paradigm. The research uses a descriptive qualitative approach, with data obtained through observations and interviews with the students and caretakers of the Islamic Boarding School. The findings show that tahfidz students are able to adapt selectively to the digital world by applying the values instilled during their time in the Islamic Boarding School, such as discipline, responsibility, and sincerity. The Islamic education paradigm serves as the foundation for shaping the students’ character so that they can utilize technology as a means of da’wah (religious propagation) and reinforcement of memorization, rather than merely for entertainment.

Abstract

This study stems from a question: “How should the foundation of a 2,000 m3 water tank be designed using standard penetration test (SPT) data for earthquake loads in accordance with SNI 1726:2019?” With a capacity of 2,000 m3, this tank has a significant volume and weight, making foundation analysis, especially regarding the effects of earthquakes, crucial, given that Indonesia is a region with high  activity. SNI 1726:2019 provides technical guidelines for earthquake-resistant design for building and non-building structures, including tank foundations. The objective is to determine the detailed dimensions of a foundation that can withstand earthquake loads in accordance with SNI 1726:2019, thereby obtaining the dimensions of the pile cap along with the required reinforcement details, as well as the sufficient bearing capacity of the piles based on standard penetration test (SPT) data. To determine the bearing capacity of the piles, the empirical formula proposed by Terzaghi and Mayerhof is used. The planning results yielded pile cap dimensions of 1600 cm in diameter and 80 cm in thickness, using fc' 30 MPa concrete and D19-150 threaded reinforcement steel. There are 50 pile foundation points with 50 cm diameter spun piles at a depth of 16 m.
