Abstract

Smart services are vital for economic development and improved user experience, yet digital inequality continues to constrain their effective deployment in emerging economies. While prior studies emphasize smart technologies and digital connectivity, limited evidence explains how connectivity is transformed into value-creating smart services. This study addresses this gap by examining the relationship between digital connectivity and the smart service value chain through a digital inclusion lens. Using a qualitative approach, a systematic literature review guided by the PSALSAR framework is conducted. Academic and international regulatory sources are analysed through content analysis and pattern recognition. The findings show that political, economic, social, and technological (PEST) factors embedded in the connectivity ecosystem are critical to smart service value creation, with socio-economic factors exerting greater influence than technology alone. The study informs conceptual development, service design, and digital policy reform for inclusive smart service ecosystems.

Abstract

This study investigates the methane (CH4) content generated through the anaerobic fermentation of cattle manure waste in a biogas digester, in support of biogas-based electricity generation development in Indonesia. A qualitative approach with a case study strategy was employed, conducted through direct field observation. The digester used was a floating dome/balloon-type unit with a slurry capacity of 300 liters, fed with 25 kg of fresh cattle manure. Primary data collected included measurements of methane gas content, hourly gas production volume, substrate pH values, and digester temperature profiles over a 10-day observation period. A comparative analysis was performed between two treatment conditions: a digester supplemented with EM4 (Effective Microorganism 4) liquid inoculant and a control digester without EM4 addition. Results indicated that the average digester temperature during the observation period was 34.18°C, which falls within the optimal mesophilic range. The measured substrate pH ranged from 6.0 to 6.7, slightly below the optimum range of 6.8–8.0 for biogas production. The floating dome digester construction was demonstrated to be capable of maintaining the anaerobic conditions required for methane gas formation.

Abstract

This study aimed to identify the causes, evaluate, and quantify the magnitude of voltage drop at SMK Ponpes Manba'ul’Ulum Cirebon. A descriptive quantitative approach using a single case study strategy was applied. Data were collected from PT PLN ULP Sumber, Cirebon, and through direct field measurements using a Digital Earth Tester, Digital Insulation Tester, and monitoring of a three-phase kWh meter. The findings revealed that the main cause of voltage drop was transformer overload at Distribution Substation CKPB, with a loading level of 91.20%, exceeding the 80% limit specified by the Indonesian Electricity Supply Standard (SPLN). Additional contributing factors included a 710-meter conductor length with a 70 mm² cross-sectional area, inter-phase load imbalance (I₁ = 105 A, I₂ = 149 A, I₃ = 141 A), and insulation resistance anomalies detected at several test points (0 MΩ at N-T, T-G, and N-G). Before transformer uprating, the voltage drop reached 28.49 V (14.92%), exceeding the SPLN 72:1987 tolerance range of 5–10%. After uprating the transformer capacity from 100 kVA to 160 kVA combined with load splitting, the voltage drop decreased to 13.57 V (6.33%) and transformer loading declined to 57.10%.

Abstract

Purpose — This paper presents a novel adaptive protection scheme for networked microgrids (NMGs) based on the Self-Organizing Map (SOM) clustering technique, addressing critical challenges in multi-microgrid protection  coordination. Design/Methodology/Approach — An SOM-based framework automatically classifies eight distinct NMG operating conditions and adapts relay settings in real time. The method is validated comprehensively on the IEEE benchmark test system for networked microgrids using PSCAD/EMTDC simulations across normal, fault, disturbance, and emergency scenarios. Findings — The proposed scheme achieves 94.7% classification accuracy on test data, reduces fault clearing times by an average of 34.3%, decreases miscoordination events by 45%, and improves the overall protection reliability index by 10.7% compared to conventional overcurrent protection. Practical Implications — The framework includes hardware specifications, commissioning procedures, and economic analysis demonstrating a 1.75-year payback period, providing a viable roadmap for real-world deployment. Originality/Value — This is the first comprehensive implementation and validation of SOM-based adaptive protection on the standardized IEEE benchmark NMG system, covering all major operating modes and transition states within a unified framework.
