Abstract

The Internet of Things (IoT) is a concept a imed 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 pla cement of sola r panels. Sola r panels are made of semiconductor materia ls capable of converting sola r energy into electricity. The prima ry issue with using sola r panels is that the power output they produce depends on the intensity of light captured by the sola r panel. Additiona lly, the temperature and air humidity a round the sola r panel also influence its performance. The objective of this resea rch is to create a system for measuring the intensity of sunlight, humidity, and temperature for the placement of IoT-ba sed sola r 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 sma rtphone 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.

Abstract

Along with the times and technology, more and more companies are switching from manual mana gement of business processes to integra ted information systems. Perintis Pha rmacy is a pha rmacy located in the Bandung district. Perintis Pha rmacy has been serving its customers since 2010. However, Perintis Pha rmacy has experienced severa l problems, where all business processes a re still carried out manually. Errors frequently occur in both the service process and the inventory management system. Errors in stock ca lculations and ordering a re the ma in obstacles. This causes the Pha rmacy to experience losses both in terms of service quality and financia lly. So it is necessa ry to implement an integra ted 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 Exponentia l 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 Pha rmacy can increase efficiency and effectiveness in managing drug supplies so as to improve service quality and financial benefit s.

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.

Abstract

As many smartphone users with the Android operating system in this digital era applications become one of the tools that can help users in various ways, one of which is to buy necessities, this can be used in companies that usually sell their products in stores that often need effort for consumers to get products. CV. Cipta Rahayu is a company enga ged in the sa le of agricultura l materia ls, the manual sales process often causes problems such as in processing transa ction data, and it takes a long time to make reports, and at least customers because customers have to come directly to the location to order goods, after that it is processed and delivered to the customer's location, this will be difficult for customers whose position is far from the CV location, Often customers also choose to buy goods in the nea rest pla ce at a much more expensive price. Therefore, the company needs a mobile application sales system with the name Tani Rahayu application that can facilitate the sales process. The purpose of this research is to design and build an Android-Based Rahayu Fa rmer Application Using the Extreme Programming (XP) Method. The result of this study is the creation of the Android-ba sed Tani Rahayu application, which will make it easier for customers to order goods without having to go to stores that take distance and time, then solve problems with shop owners or CVs in the process of customer orders and bookkeeping, then overcome customers switching to purchasing agricultura l materia ls at other stores due to the remote location of the store, and attra ct many more other customers.

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 wa s to analyze the relationship between the determinant factors of SIMAK utilization on the user's behaviora l intention, to ana lyze the rela tionship between habit and facilitating condition factors to user behavior, and to ana lyze 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, Ga rut University. Measurements were carried out using the UTAUT 2 model construct, then testing wa s carried out with the Structura l Equation Model (SEM) and SPSS. This finding proves that 1) performance expectancy, effort expectancy, socia l influence, facilitating condition, and hedonic motivation have no effect on behaviora l intention. 2) habit and trust in information have an effect on behaviora l intention. 3) habit and facilitating conditions have no effect on user behavior. 4) behaviora l intention has an effect on user behavior. The implications of this resea rch can be considered in the application of information and communication technology in improving performance.

Abstract

Currently, the development of Information Systems (IS) and Information Technology (IT) is progressing very quickly. The development of IS/IT cannot be separated from the role of humans who continue to improve and look for new innovations at all times so that technology can make people's daily work easier. The rapid development of IS/IT and the use of IS/IT in aspects of life has resulted in the integration of computerized systems that are not limited by time and distance via the network.internet. SI/IT also provides data accuracy in processing data compared to manual methods. The positive impact of IS/IT in the business world is not only felt by large-scale businesses but is also felt by medium and small businesses, where involving IS/IT in running their business will make business easier, faster and minimize human error.Main Quality (Qu Cuci) Garut is a service that operates in the service sectorlaundry kilos such as carpets, daily clothes and other types of fabric.
