Abstract

The Internet of Things (IoT) is a concept aimed at expanding the benefits of continuous internet connectivity. IoT can be utilized for monitoring the intensity of light, temperature, and air humidity in the surroundings to determine suitable locations for the placement of solar panels. Solar panels are made of semiconductor materials capable of converting solar energy into electricity. The primary issue with using solar panels is that the power output they produce depends on the intensity of light captured by the solar panel. Additionally, the temperature and air humidity around the solar panel also influence its performance. The objective of this research is to create a system for measuring the intensity of sunlight, humidity, and temperature for the placement of IoT-based solar panels using LDR and DHT 11 sensors. The development of this system involves the use of the Prototyping Method. The device's design incorporates the NodeMCU ESP32 microcontroller, and monitoring is conducted through a smartphone using the Blynk application. The LDR and DHT 11 sensors are connected to the NodeMCU ESP32's GPIO as data receivers. A WiFi network is used to transmit intensity of light, temperature, and humidity data from the NodeMCU ESP32 to the smartphone, where it is displayed through the Blynk application. This research is beneficial for identifying the most suitable locations for solar panel placement. Keywords : IOT, Solar panel, Monitoring, NodeMCU ESP32, Blynk

Abstract

SatuSehat is a contact tracing application that replaces the PeduliLindungi application initiated by the Government of Indonesia with the aim of tracking the Covid-19 Virus. The success of the application can be known by analyzing sentiment reviews. In addition to the high number of reviews, there are also other things that need to be highlighted, namely the pattern of reviews that are not in accordance with refined spelling and diverse topics, so that identifying a topic from a collection of reviews is very difficult and takes a lot of time if done manually by humans. This research describes sentiment analysis and topic modeling on SatuSehat app user reviews. By applying Support Vector Machine (SVM) method for sentiment analysis and Latent Dirichlet Allocation (LDA) for topic modeling, this study reveals the views and trends expressed by users. The analyzed review data from Google Play Store includes 171,428 positive reviews and 131,246 negative reviews. The sentiment analysis results indicated the dominance of positive responses. LDA modeling resulted in 8 identified topics, from health concerns to app appreciation. However, negative topics included vaccination challenges, access issues, and app functionality. This research provides insight into users' perceptions of the SatuSehat app, providing a basis for further development and improvement of the app. Keywords: Sentiment Analysis; Topic Modeling; OneHealth App; SVM; LDA

Abstract

Along with the times and technology, more and more companies are switching from manual management of business processes to integrated information systems. Perintis Pharmacy is a pharmacy located in the Bandung district. Perintis Pharmacy has been serving its customers since 2010. However, Perintis Pharmacy has experienced several problems, where all business processes are still carried out manually. Errors frequently occur in both the service process and the inventory management system. Errors in stock calculations and ordering are the main obstacles. This causes the Pharmacy to experience losses both in terms of service quality and financially. So it is necessary to implement an integrated system so that inventory management becomes more effective and efficient, namely the application of an Enterprise Resource Planning (ERP) system that is integrated with forecasting simulations to obtain a more accurate amount of drug procurement. Demand forecasting is done using Time Series data with the Single Exponential Smoothing method, given the fluctuating demand every month. Then the forecasting results are integrated with the ERP system using the Odoo 14.0 application in the invoice, purchase, and inventory modules. By using the Odoo 14.0 application, it is expected that Perintis Pharmacy can increase efficiency and effectiveness in managing drug supplies so as to improve service quality and financial benefits.

Abstract

The application of information and communication technology is often not achieved due to the unwillingness of users to accept and use the existing system. The purpose of this study was to analyze the relationship between the determinant factors of SIMAK utilization on the user's behavioral intention, to analyze the relationship between habit and facilitating condition factors to user behavior, and to analyze the relationship between user behavior intention and user behavior. This study used a quantitative method by conducting a questionnaire survey to Digital Business Study Program student, Garut University. Measurements were carried out using the UTAUT 2 model construct, then testing was carried out with the Structural Equation Model (SEM) and SPSS. This finding proves that 1) performance expectancy, effort expectancy, social influence, facilitating condition, and hedonic motivation have no effect on behavioral intention. 2) habit and trust in information have an effect on behavioral intention. 3) habit and facilitating conditions have no effect on user behavior. 4) behavioral intention has an effect on user behavior. The implications of this research can be considered in the application of information and communication technology in improving performance.
