Abstract

The Electricity Infrastructure Control and Maintenance (P2TL) program aims to increase efficiency and effectiveness in the installation of electricity meters, both postpaid and prepaid. This study analyzes the performance of the P2TL program by focusing on the comparison between the installation of postpaid and prepaid electricity meters, as well as their impact on operational efficiency and customer satisfaction. Objective: To assess the effectiveness of the P2TL program in the implementation of electricity meter installation, and to analyze the performance differences between postpaid and prepaid systems. The P2TL (Penertiban Pemakaian Tenaga Listrik) Performance Program plays a crucial role in ensuring the proper installation and regulation of postpaid and prepaid electricity meters. This program is designed to monitor, control, and prevent electricity usage violations, ensuring that energy distribution remains efficient, fair, and compliant with national electricity regulations. This study aims to evaluate the effectiveness of the P2TL program in enhancing the accuracy and security of electricity meter installations. By analyzing installation procedures, technical challenges, and consumer compliance, the research highlights key performance indicators that determine the success of P2TL in both postpaid and prepaid systems. Data collection was conducted through field observations, interviews with technical personnel, and analysis of customer feedback to understand the program’s impact on service quality and electricity loss prevention.

Abstract

Pembangunan berkelanjutan saat ini menjadi prioritas global untuk menjaga kelestarian lingkungan sekaligus memenuhi kebutuhan energi masyarakat. Penggunaan sumber daya energi yang dapat diperbarui, seperti energi matahari dan angin perlu dioptimalkan, khususnya di wilayah yang memiliki potensi besar seperti kawasan pesisir Danau Tondano. Fokus penelitian ini adalah untuk memaksimalkan pemanfaatan energi secara efisien. terbarukan melalui pemanfaatan pembangkit listrik hybrid kombinasi antara energi matahari dan eneri angin, di kawasan pesisir Danau Tondano. Dalam penelitian ini digunakan dua pendekatan, yaitu eksperimen dan simulasi. Proses eksperimen dijalankan dengan cara melakukan pengujian langsung terhadap sistem PLTS dan PLTB skala kecil di lokasi penelitian, sedangkan simulasi digunakan untuk membandingkan hasil aktual dengan hasil estimasi berbasis data sekunder dan perhitungan manual menggunakan perangkat lunak spreadsheet (Microsoft Excel). Hasil observasi menunjukkan bahwa kombinasi PLTS dan PLTB dapat meningkatkan efisiensi sistem, berdasarkan data pengujian sistem PLTS dapat menghasilkan 297 Wh / hari dan data pengujian sistem PLTB dapat menghasilkan 431 Wh / hari sehingga didapat hasil dari kombinasi kedua sistem ini adalah 729 Wh / hari.

Abstract

The digital transformation of education has led to the widespread adoption of e-learning platforms, with Google Classroom becoming one of the most widely used tools globally. However, high adoption rates do not automatically guarantee service quality, necessitating a systematic quality management approach. This study analyzes the application of Quality Management System (QMS) principles to the Google Classroom e-learning service based on ISO 9001:2015. The research employs a literature review method, mapping Google Classroom features to the seven QMS principles: customer focus, leadership, engagement of people, process approach, continual improvement, evidence-based decision-making, and relationship management. The findings indicate strong support for user-centered design, structured instructional workflows, and continual improvement. However, gaps remain in formal quality documentation, internal audit mechanisms, and structured management review processes. Full ISO 9001:2015 compliance requires educational institutions to complement Google Classroom’s operational capabilities with formal quality documentation, audit mechanisms, and structured vendor relationship management.

Abstract

The demand for self-powered systems has driven the development of piezoelectric-based smart floors. This study evaluates the performance of a 60 x 60 cm smart tile prototype integrating 20 units of Lead Zirconate Titanate (PZT) piezoelectric modules in a parallel configuration. The primary objective is to analyze the effects of dynamic user mass 47 kg, 56 kg, 81 kg, and 106 kg and loading duration 1 minute, 2 minutes, and 3 minutes via continuous stepping on the electrical charge retention of a 470 µF electrolytic filter capacitor under a 1.000 Ω resistive load. Temporal data collection was conducted to measure the maximum voltage (Vmax) and the transient decay time (tdischarge) to 0 V. Experimental results indicate that an increase in user mass is directly proportional to Vmax elevation, where a 106 kg mass over a 3-minute duration yielded the highest peak voltage of 6.9 V. The charge depletion characteristics revealed a physical anomaly where the actual discharge duration extended from 200 seconds to 1.872 seconds, significantly exceeding the theoretical RC circuit time constant τ = 0.47 seconds. This phenomenon confirms a strong dielectric absorption effect alongside the dominant influence of the instrument's high internal input impedance during the open-circuit phase. This study provides crucial empirical insights for designing practical-scale power management systems in smart floors.

Abstract

This study investigates the influence of variations in load position on the mechanical response of simply supported beams using a web-based computational modeling approach. As structural analysis increasingly shifts toward accessible, browser-based simulation platforms, understanding how such tools represent classical beam behavior is essential for both educational applications and preliminary engineering design. A prismatic beam with a uniform cross-section was modeled and subjected to a concentrated point load applied at several positions along its span, namely 0.25L, 0.50L, and 0.75L, where L denotes the total span length. Web-based finite element analysis was used to compute the deflection, bending moment, and shear force distributions for each loading scenario, and the results were verified against analytical solutions derived from classical beam theory. The findings indicate that load position significantly affects the magnitude and distribution of internal forces and deflection. The maximum deflection and bending moment occur when the load is applied at midspan, whereas eccentric load positions produce asymmetric bending moment and shear force diagrams, with lower peak deflections and shifts in the locations of the maximum responses. The web-based model showed close agreement with the analytical results, with deviations of less than 5% across all tested configurations, confirming that browser-based computational tools can provide reliable and rapid insights into beam behavior without requiring specialized desktop software. These findings support the use of web-based computational modeling as a practical and accessible tool for structural analysis education and preliminary design evaluation.
