Abstract

PT Batra Alam Sejahtera is a company engaged in water drilling services and clean water management. The clean water distribution system carried out by the company is to collect water flowed from several boreholes by submersible pumps to the storage tank, so that damage to one of the submersible pumps will affect the amount of water supply produced and have an impact on the water discharge that can be flowed to consumers. Submersible pump well 2 has the highest downtime among the 3 submersible pumps used, the engine performance should be maintained to ensure all consumers can be supplied with clean water, so an analysis of pump maintenance is needed so that pump performance can be maintained. To overcome this problem, this research aims to find the cause of damage to the pump with the Fault Tree Analysis method and determine the maintenance schedule time with the Reliability Centered Maintenance method. The initial step is to find the cause of the damage by creating a fault tree structure, followed by the calculation of TTR, TTF, MTTR, MTTF, Reliability and maintenance time intervals so that the final goal of the research is to create a maintenance schedule for both submersible pump components, namely Electromotor and Impeller. Based on the results of the fault tree structure analysis, the causes of submersible pump damage can be caused by the use of inappropriate electromotor, impeller, and cable specifications, damaged bearings, interference from the electricity network used, no protection system, inappropriate automatic radar settings, damaged electromotor seals, no regular maintenance schedule, workers lack of understanding and lack of thoroughness when installing. Based on the results of this study with a reliability value of 80%, the inspection interval time for the Electromotor component is 1002.2 hours and the Impeller component is 1637.7 hours with maintenance actions taken, namely inspection, cleaning, and component replacement.

Abstract

This paper proposes a joint-fusion multi-modal Artificial Intelligence of Things (AIoT) framework for precision horticulture on chili and tomato. We fuse time-series IoT signals (air/leaf temperature, humidity, soil moisture, pH, EC, PAR) with RGB/multispectral images of leaves, fruits, and canopy via an attention-based shared representation. In a 500 m² field trial in Majalengka with >5,000 labeled images and synchronized IoT streams (10-minute interval), our model outperforms single-modal baselines. For chili leaf disease detection, joint fusion reaches 90.0% accuracy (IoT-only 72.0%, vision-only 81.0%). For tomato maturity classification, it achieves 92.0% accuracy (IoT-only 68.0%, vision-only 84.0%). For yield estimation, the multi-modal regressor attains R² = 0.89. We detail data synchronization, train/validation/test splits, baseline configurations (IoT-LSTM, CNN/ViT, early/late fusion), and deployment on an edge-cloud pipeline. The results indicate that modeling cross-modal interactions improves robustness and decision support for irrigation, fertilization, and harvest scheduling. We conclude with ablation analyses and practical implications for Indonesian precision agriculture.

Abstract

Cats are pets that are susceptible to various diseases if not properly cared for, especially if the owner does not recognize the symptoms of disease in cats, potentially leading to incorrect treatment and worsening the cat's health condition. This study uses an expert system website to diagnose diseases in cats, using the Certainty Factor (CF) method. Certainty Factor is a method used to determine whether a fact has certainty or uncertainty, in the form of a metric that is generally applied in expert systems. This method is used to predict the possibility of disease based on symptoms inputted by the user, so that it can provide initial diagnosis results. The results of the study then conducted a questionnaire to see the usefulness of the system and obtained the results that 91.32% of respondents felt this system was appropriate and useful. In the future, it is hoped that this system can be developed with suggestions for initial treatment or appropriate medication for cats.

Abstract

Bullying in schools remains a serious issue that requires prompt and systematic handling. One of the main challenges in reporting cases is the absence of an integrated system that facilitates both students and school authorities in submitting and following up reports. This study aims to design and implement a web-based bullying case reporting system using the Extreme Programming (XP) development methodology. The research stages include planning, system design with Unified Modeling Language (UML) and Entity Relationship Diagram (ERD), implementation using PHP, HTML, CSS, JavaScript, AJAX, and MySQL database management system, as well as testing through the black box testing method. The results indicate that the developed system effectively supports the reporting process, improves transparency, and simplifies follow-up actions by the school. The black box testing results demonstrate that the system’s functionalities run as expected without significant errors. Therefore, the application of the XP methodology proves to be effective in accelerating the system development process, maintaining flexibility in addressing changing requirements, and delivering a system that meets user expectations. This research is expected to provide a practical solution to support bullying prevention and management in schools through web-based technology.
