Abstract

This study presents a low-cost and scalable multi-channel power data acquisition system for real-time solar photovoltaic (PV) panel monitoring, addressing the limitations of conventional single-channel approaches that provide only aggregate system measurements. The proposed system enables simultaneous per-panel measurement to support detailed performance analysis and improved fault localization. The system is implemented using an ESP32 microcontroller integrated with multiple calibrated INA219 sensors, which are connected via the I²C protocol to measure voltage, current, and electric power. A modular hardware design supports three independent PV channels, while data handling is achieved through dual-mode operation, consisting of local microSD card storage and wireless data transmission to the ThingSpeak IoT platform for real-time visualization. Calibration results demonstrate high measurement accuracy, with average errors below 1%, a voltage root mean square error (RMSE) of less than 0.07 V, and a current RMSE of less than 7 mA. Field testing conducted over two consecutive days confirms stable and uninterrupted operation, achieving 100% data acquisition reliability. The recorded data clearly reveal per-panel performance differences under real operating conditions, enabling effective identification of mismatch behavior among panels. The proposed system provides an affordable, reliable, and scalable solution for distributed PV monitoring, making it suitable for multi-panel and remote photovoltaic installations. Future improvements will involve temperature-based efficiency analysis and the integration of thermal management strategies to enhance photovoltaic performance.

Abstract

Music has a significant impact on the way a person thinks and feels in their daily activities. This study aims to categorize the types of music that are suitable for learning activities by using Spotify's audio feature, to create a more flexible and personalized music recommendation system. The dataset used comes from Spotify Study Music which consists of 172,819 songs with 12 audio features, which are grouped into three main categories, namely Pop tracks, Classical soundtracks, and Lo-fi tracks. The research process includes data pre-processing, handling class imbalances using SMOTE, data normalization, feature significance Analysis, Cross Validation, and feature reduction. Normalization results show that all features have been in the range of 0.0-1.0 without changing the characteristics of the original distribution. The Random Forest Model performed exceptionally well with an average accuracy rate of 99% on cross-validation and 99.9% on training data, indicating the model's ability to efficiently recognize musical patterns. Important Feature Analysis shows that energy, loudness, acousticness, instrumentalness, and liveness have the most significant influence in distinguishing music characteristics for learning, while mode, popularity, duration_ms, and danceability when removed using Feature Reduction analysis show a significant decrease in accuracy. This study recommends maintaining the features of acousticness, instrumentalness, and liveness because it plays an important role in maintaining the stability and accuracy of music classification models that support the learning process.

Abstract

Indonesia’s population continues to grow each year, including in Jember Regency, which reached 2,584,771 people in 2023. Population density contributes to various health issues, such as the high maternal mortality rate (MMR) and infant mortality rate (IMR), with 17 maternal deaths and 81 infant deaths recorded in 2023. The primary causes of MMR include pregnancy at too young or old an age, short birth spacing, and delays in referral, while IMR is mainly caused by asphyxia and low birth weight (LBW) due to premature birth. The government has implemented a midwife and traditional birth attendant partnership program to address this issue. However, information regarding high-risk areas remains inadequately conveyed. Therefore, this study develops a Geographic Information System (GIS)-based system using the K-Means Clustering method with a predefined number of clusters to classify high-risk maternal and infant mortality areas. The results show that the K-Means Clustering method with a fixed number of clusters (k = 5) successfully groups Jember Regency into five risk-level clusters, namely very high, high, medium, low, and very low. Visualization through GIS facilitates effective access to spatial information and supports the identification of priority areas for targeted health interventions, aiming to reduce maternal and infant mortality rates more effectively.

Abstract

Diabetic retinopathy (DR) is a leading cause of preventable blindness worldwide and is becoming a significant public health concern in Indonesia due to the rising prevalence of diabetes. Early detection is critical, yet access to ophthalmologists and conventional fundus cameras remains limited in many primary healthcare facilities. To address these challenges, this study proposes a cost-effective, web-based intelligent system for early detection of DR using smartphone-based fundus adapters and deep learning.A hybrid dataset was employed, combining publicly available fundus image repositories with locally collected retinal images from Indonesian healthcare facilities, annotated by ophthalmologists. Images were preprocessed through normalization, cropping, artifact removal, and augmentation to address variability, particularly from smartphone acquisitions. A DenseNet-121 convolutional neural network was fine-tuned on this hybrid dataset to classify DR into five severity levels according to the International Clinical Diabetic Retinopathy Disease Severity Scale. Model performance was evaluated using accuracy as the primary metric, with results compared against ophthalmologist annotations.The proposed system demonstrated promising performance in classifying DR severity levels, showing that combining public and local datasets improves contextual relevance and model robustness. Furthermore, integration into a web-based platform enables healthcare workers in primary care to upload fundus images, obtain real-time classification results, and facilitate referral decisions for severe cases.This study contributes to the development of an accessible and scalable screening tool for DR in Indonesia by integrating affordable imaging hardware, locally relevant datasets, and an AI-powered classification system. The approach has the potential to reduce reliance on expensive equipment and specialists, supporting national efforts to prevent diabetes-related blindness.

Abstract

This paper presents an Improved Blue Monkey (IBM) optimization algorithm for enhancing voltage stability and reducing power losses in distribution networks through optimal placement and sizing of Distribution Static Var Compensators (D-SVCs). The IBM algorithm modifies the original Blue Monkey metaheuristic by incorporating a random inertia weight to accelerate convergence and improve exploration-exploitation balance. Benchmark function tests demonstrated the IBM’s superiority over the original BM and Particle Swarm Optimization (PSO) in solution accuracy, stability, and convergence speed. The proposed method was applied to the IEEE 33-bus system under varying load conditions, achieving optimal D-SVC placements at buses 7, 14, and 31, with reductions of 22.17% and 18.15% in active and reactive power losses, respectively, and an increase in minimum voltage from 0.9131 p.u. to 0.9590 p.u. Comparative analysis with the Modified Artificial Rabbit Optimization (MARO) method confirmed the IBM’s consistent performance advantage, including better Fast Voltage Stability Index (FVSI) values. The results validate the IBM algorithm as an effective and robust tool for reactive power compensation optimization in modern power distribution systems.

Abstract

This study presents the design and implementation of an Internet of Things (IoT)–based feed control system for gamefowl (fighting chickens) to ensure consistent rations when the breeder is away. The system combines a load cell with an HX711 weight-sensor interface to measure dispensed feed, an Arduino Uno microcontroller to execute control logic, and an ESP8266 Wi-Fi module to exchange data with a cloud service. An Android application allows users to set the target feed mass in grams, start or stop dispensing, and monitor real-time weight feedback. A prototype development method was applied, covering requirement elicitation, hardware and software design, implementation, and functional testing. Performance was evaluated through 20 dispensing trials using a 10 g tolerance limit derived from breeder practice. The prototype achieved successful dosing in all trials, with measured outputs remaining within the defined tolerance and providing immediate feedback to the mobile interface. The results indicate that the proposed system can automate portioning, reduce the risk of overfeeding or underfeeding, and support remote feed management for small-scale poultry operations.

Abstract

Teacher performance appraisal in Madrasah Diniyah Hidayatul Mubtadiin was previously carried out manually using spreadsheets and paper archives, leading to slow processing, input errors, and weak traceability of historical results. This study proposes and implements a web-based Decision Support System (DSS) to automate the appraisal process and support transparent ranking using the Profile Matching method. Teacher performance is assessed on five aspects pedagogic, professional, personality, discipline, and social using a 1–5 rating scale, with an ideal target profile set to 5 for all factors. For each factor, the system computes a GAP between actual and target values, converts the GAP to a weight via a predefined mapping, and aggregates scores by separating Core Factors and Secondary Factors. Aspect scores are calculated using a 60%:40% composition between core and secondary components, and overall rankings are produced through inter-aspect weighting. The DSS is developed with the Laravel MVC framework and supports three roles (admin, teacher, and principal), including principal verification and automatic generation of signed PDF reports for each appraisal period. Functional validation using black-box testing across ten key scenarios shows that all critical modules—data management, scoring input, computation, verification, ranking, and reporting—operate as expected. The proposed system reduces manual workload, accelerates semester appraisal activities, and improves auditability of appraisal decisions for madrasah management.
