Abstract

CV. Anugerah Alam Indonesia is a company engaged in the production and sale of herbal medicines. The main issue faced by the company is the inaccuracy in estimating production quantities, which often leads to either overstocking or stock shortages. This research aims to develop a sales forecasting application for herbal products using the simple linear regression method as part of data mining techniques. The sales data used in this study spans from 2020 to 2025 and focuses on ten selected herbal products. The application is web-based, developed using the PHP programming language and Laravel framework, with MySQL as the database. The forecasting process involves calculating regression constants and coefficients based on historical sales data and evaluating the prediction results using the Mean Absolute Percentage Error (MAPE) metric. The test results show that the forecasting model demonstrates varying levels of accuracy, ranging from very good to acceptable, depending on the product. By implementing this system, the company can optimize its production and distribution processes, avoid resource waste, and improve operational efficiency.

Abstract

The procedure of recording the attendance of casual workers at the Secretariat of the Regional People's Representative Council (DPRD) of Minahasa Regency is still carried out manually, which is easily exposed to recording errors, manipulation of data, and requires ineffective time and energy. To solve this problem, this research aims to design and develop a web-based attendance recording system by applying the Prototype method. This method was chosen because it supports the development of a system that is interactive and responsive to user needs through a series of iterations between developers and users. The designed system enables electronic attendance recording, employee data management, as well as the presentation of attendance reports automatically and precisely. The pilot test shows that the system is able to increase efficiency and accuracy in the attendance administration process, as well as facilitate supervision by the authorities. Therefore, the system is expected to serve as an effective solution to support a more modern and transparent administrative management within the Secretariat of Minahasa Regency Parliament.

Abstract

Medical records are documents containing patient identity data, examination, treatments, procedures, and other services provided to patient. The management and storage of medical records at Advent Hospital are still conducted manually, leading to data duplication, input errors, and time-consuming data retrieval processes. This study aims to develop a web-based medical record information system to enhance the efficiency of patient data processing. The system was build using PHP and MySQL with Software Development Life Cycle (SDLC) cascade model (waterfall model). Black box testing results indicate that all functions of the medical record system operate efficiency and validly. The system is effective in reducing data duplication and accelerating data retrieval.

Abstract

This research analyzes the efficiency comparison between the Auxiliary Power Unit (APU) and Ground Power Unit (GPU) on the Airbus A320 aircraft's electrical system during ground operations. Aircraft operations require a stable power supply, provided by either an internal APU or an external GPU. Although the APU offers flexibility, its high fuel consumption and significant environmental impact are considerable concerns. Conversely, the GPU is deemed more efficient and environmentally friendly. The study aims to calculate energy consumption, analyze efficiency, and recommend the most efficient and environmentally sound electrical power source. The method employed is a quasi-experimental field observation, involving direct data collection from a Houchin LTD model C690 GPU unit. Data collection was conducted over 7 days, from June 1 to June 7, 2025. Data analysis includes mathematical calculations for energy efficiency and operational economic analysis. Research findings indicate that the GPU significantly outperforms the APU. The diesel GPU exhibits an energy efficiency of approximately 31.30%, considerably higher than the APU's around 1.54% (based on 7 days of data). The GPU also presents superior electrical power quality, characterized by a higher Power Factor and lower Total Harmonic Distortion (THD). It is recommended that airlines prioritize GPU usage, and airport authorities expand Fixed Electrical Ground Power (FEGP) infrastructure to enhance energy efficiency and reduce operational costs.

Abstract

Switched Reluctance Generators (SRGs) have attracted attention due to their robust construction, low cost, and high fault tolerance, suitable for extreme environments. However, SRGs suffer from torque ripple and acoustic noise due to the non-linear torque-excitation current relationship. Although SRG component optimization has been investigated, a gap exists in the analysis of the effect of stator excitation current on the drive torque in a single-phase "6/6" SRG design with external amplification. This study analyzes the impact of varying stator excitation current on the drive torque of a single-phase 6/6 SRG. The methodology includes design, finite element analysis (FEA), and testing of an initial drive torque prototype. Results show that increasing the stator coil supply voltage results in a greater magnetic force, which counteracts the mechanical torque on the rotor shaft. This understanding is crucial for optimizing torque performance, mitigating ripple, and improving SRG efficiency for future applications.
