Abstract

The information system in a music school business will be crucial in driving the success and progress of the company. Where customer satisfaction can be achieved when the right strategy can be realized in achieving organizational goals. So it is deemed necessary to have an information system to increase business competitiveness for a music school. In information system planning, it is very necessary to use SWOT analysis to get a company's view regarding strengths, weaknesses, opportunities and threats. Which is used to be able to see more comprehensively for decision making purposes. The research carried out aims to analyze external and internal factors. External factors influence opportunities and threats. Factors that occur outside the company that will influence decision making in the company and internal factors which include strengths and weaknesses. In this research, the author made observations at one of the music schools to obtain data, documents, and conducted interviews with business people as sources of information needed by the author. The final results of this research are the SO Strategy (strengths opportunities), the ST Strategy (strengths threats), the WO Strategy (weaknesses opportunities) and the WT Strategy (weaknesses threats). SWOT analysis in the design of an Information system will be very helpful in making decisions on the design of Information Systems and Information Technology in the future for music schools. The suggestion from this research is that the results of the SWOT analysis are only the first step in designing a business strategy. And what will really influence the success of achieving company goals is the next step in determining company decisions regarding Information Systems and Information Technology.

Abstract

Value chain analysis in planning a music school system can complement a company's strategy to compete in the music school business. Where action will focus on product elaboration and service processes. So in order to increase success in music school business competition, it is necessary to use value chain analysis to determine the costs associated with organizational activities from providing facilities to product design and marketing. Which can be used for decision making purposes in business strategy. The research carried out aims to obtain competitive factors such as level of integration, industry panorama, segment panorama and geographic panorama. Where it will influence decision making in the company. In this research, the author carried out observations at a music school to study data, documents, and also conducted interviews with company owners as a source of information data needed by the author. The final result of this research is a mapping of the work process at a music school, which consists of main activities and supporting activities. Value chain analysis within the scope of a business system design will be very helpful in decision making when designing Information Systems and Information Technology for music schools. The suggestion from this research is that the results of the value chain analysis are expected to contribute to the design of a business strategy. Which will greatly influence the achievement of company goals. Also helps in making company decisions on Information Systems and Information Technology planning.

Abstract

Cardiovascular health and blood oxygen levels are critical indicators for monitoring a person's physical condition, especially during activities or exercise. Monitoring these two parameters is essential to ensure that an individual remains within safe limits to continue physical exertion. Therefore, a portable device capable of accurately and in real-time measuring blood oxygen saturation (SpO₂) and heart rate (BPM) is required. This study aims to design and develop a pulse oximeter device based on the Arduino Uno microcontroller using the MAX30102 sensor, equipped with LED indicator lights and a keypad as a user input interface. Users can input their age through the keypad, and the system calculates their maximum BPM as a safe threshold for physical activity. The LED lights serve as visual indicators to signal whether the user's SpO₂ and BPM values are within the normal range. Testing results show that the device is capable of measuring blood oxygen saturation with an accuracy of 99.97% and heart rate with an accuracy of 98%. With its compact size, this device has the potential to be used practically in various situations, both by individuals and healthcare personnel for preliminary health monitoring.

Abstract

This study aims to analyze and predict carbon dioxide (CO₂) concentration in parts per million (PPM) based on temperature and humidity using DHT22 and MQ135 sensors integrated with an ESP32 microcontroller as an Internet of Things (IoT) system. Data were collected in two measurement sessions. The first session was conducted from 16:00 to 20:00 with a one-second sampling interval, during which significant spikes occurred due to exposure to insecticide fumes. The second session was carried out from 00:00 to 08:00 with a two-second sampling interval, producing approximately 13,000 more stable data points suitable for machine learning analysis. The collected data were processed using several machine learning algorithms, including Linear Regression, Random Forest, CatBoost, LightGBM, XGBoost, and Neural Network (Keras). The results indicate that the CatBoost model achieved the best performance, with an accuracy of 98.9%, a Mean Absolute Error (MAE) of 2.75, and a Mean Relative Error (MRE) of 1.08%. This study demonstrates that an ESP32-based IoT implementation using integrated gas and temperature sensors can be utilized as a simple air quality prediction system and serve as a foundation for developing future intelligent environmental monitoring devices.
