Fast, transparent, and easily accessible public services are essential in government agencies, particularly in managing public complaints. This study aims to develop a web-based public complaint service information system at the ATR/BPN Mentawai Islands Office to make complaint submission, handling, and monitoring more effective and efficient. The system design applies the Unified Modeling Language (UML) with use case, class, activity, and sequence diagrams to illustrate system needs and workflows, alongside the System Development Life Cycle (SDLC) as a phased development approach. The system is built using PHP and a MariaDB database for user and complaint data storage, with functionality tested through the Black Box method. Key features include user registration, login, complaint submission, and status tracking. All features operate as intended, delivering a transparent and responsive complaint service process. This system prioritizes accessibility, data security, comprehensive features, and structured documentation, successfully improving service quality at the ATR/BPN Mentawai Islands Office.

Autonomous decision-making systems increasingly rely on complex artificial intelligence models to operate in dynamic and safety-critical environments. While these models provide strong predictive capabilities, their black-box nature limits transparency, trust, and accountability. This study proposes a structured research methodology for integrating Explainable Artificial Intelligence (XAI) into autonomous decision-making systems. The research adopts a conceptual–analytical approach to develop an explainability-oriented framework that embeds transparency across perception, decision-making, and action execution stages. The methodology includes literature-driven problem identification, conceptual framework construction, classification and mapping of XAI methods, and formulation of explainability evaluation criteria. The results demonstrate that effective explainability in autonomous systems requires a hybrid integration strategy, combining in-model transparency with post-hoc explanation mechanisms. A structured mapping of XAI techniques to autonomous system components and a conceptual decision-flow diagram are presented to illustrate explainability integration. The findings highlight that layered and context-aware explainability enhances system interpretability, supports human oversight, and improves safety relevance without compromising autonomous operation. This study contributes a reusable methodological foundation for the design and evaluation of explainable autonomous systems, offering practical guidance for future empirical validation and real-world deployment in safety-critical applications.

The government's initiative to enhance energy resilience and independence includes the augmented use of green energy. PLTA Singkarak is a renewable energy facility that harnesses water from Lake Singkarak to operate its turbines, featuring an average tailrace discharge of 30 m³/s. The Singkarak Hydroelectric Power Plant receives its energy from PLN's Singkarak Substation, utilizing a 5 MVA transformer for distribution to meet its own consumption needs. Consequently, each month, the Singkarak Hydroelectric Power Plant must reduce its total kWh output by its own use, averaging 4,127.8 kW each day. A small-scale Micro Hydro power plant will be developed to utilize the potential water source at the outflow of the Singakrak Hydroelectric Power Plant, serving as the primary supply for the facility, and so decreasing the company's performance target for its own consumption. A sufficiently big outflow tailrace discharge is likely to be repurposed for a micro-hydropower plant. The initial elevation of the Singkarak Hydroelectric Power Plant tailrace exit is 71 meters above sea level, whereas the end elevation is 67 meters above sea level, as measured by hand. A micro-hydropower plant (PLTMH) can be engineered with a net head of 3.8 m and a flow rate of 10.618 m³/s, yielding a maximum power output of 327.8 kW. The turbine employed is a Kaplan turbine, while the generator utilized is a 3-phase synchronous generator, with both components functioning at 1000 rpm . This PLTMH design can supplant the self-consumption of the Singkarak hydropower plant (PLTA), hence enhancing the system's energy efficiency.

Kegiatan pelaporan pada Perumda Tirta Sakti Kabupaten Kerinci Jambi masih bertumpu pada pencatatan manual yang menyisakan celah, mulai dari keterlambatan informasi hingga ketidaksinkronan data. Situasi ini tidak hanya memperlambat alur kerja, tetapi menyulitkan penelusuran laporan ketika dibutuhkan secara cepat. Penelitian ini menghadirkan sistem informasi pelaporan pertama di Perumda Tirta Sakti yang menyatukan tiga modul utama yaitu data pelanggan, pemakaian air, dan pengaduan pelanggan dalam satu platform digital terpadu. Integrasi ketiga modul tersebut belum pernah dikembangkan sebelumnya di Perumda Tirta Sakti, sehingga menjadi solusi yang efektif untuk mengatasi fragmentasi data yang selama ini yang masih menggukan metode pencatatan manual. Pendekatan yang digunakan mengacu pada System Development Life Cycle (SDLC) dengan model Waterfall, dimulai dari tahap analisis kebutuhan hingga pengujian sistem. Perancangan dilakukan menggunakan UML dan ERD, kemudian diimplementasikan dengan PHP dan MySQL. Sistem yang dihasilkan menunjukkan kemampuan dalam mereduksi kesalahan pencatatan sekaligus mempercepat akses informasi. Di sisi lain, pelanggan tidak lagi bergantung pada kunjungan langsung untuk menyampaikan keluhan. Perubahan ini cukup signifikan, terutama pada efisiensi kerja dan respons layanan yang sebelumnya belum sepenuhnya terefesiensi.

Indonesia is located within the Pacific Ring of Fire, one of the most seismically active regions in the world due to the interaction of multiple major tectonic plates. Understanding the spatial distribution of earthquakes and accurately estimating their magnitudes is essential for effective disaster risk assessment and mitigation planning. This study aims to analyze earthquake distribution patterns and develop a machine learning-based approach to predict earthquake magnitude using seismic data from the Meteorology, Climatology, and Geophysics Agency (BMKG). The study employs two machine learning methods: K-Means Clustering to identify spatial groupings of earthquake events and Random Forest Regression to predict magnitude based on spatial and temporal features. The dataset consists of 67 earthquake events recorded in February 2026, including attributes such as latitude, longitude, depth, magnitude, and occurrence time. Clustering results indicate that the optimal number of clusters is k = 4, with a Silhouette Score of 0.3444, suggesting a moderate clustering structure. This implies that spatial patterns are present, although cluster separation is not yet well-defined. The Random Forest model achieved an R² of 0.7382 on training data and 0.0975 on testing data, indicating overfitting likely due to the limited dataset size. Feature importance analysis reveals that longitude contributes the most (43.7%), followed by depth (29.6%), latitude (20.6%), and time (6.0%). These findings highlight the dominant role of spatial factors in Indonesia’s seismic activity. However, the limited dataset restricts model generalization; therefore, future studies should use larger datasets and incorporate additional geophysical parameters to improve predictive performance.
