Abstract

Deaf is fourth in the list of persons with disabilities in Indonesia at 7.03%. Deaf people communicate using sign language both when communicating with fellow deaf people and with normal people. The problem that arises is that few normal people master sign language, especially the Indonesian Sign System (SIBI) so that it becomes an obstacle when they have to communicate with deaf people. This study aims to classify the alphabet in SIBI except the letters J and Z with a total of 24 classes. Classification is done by comparing three CNN architectures, namely MobileNetV2, MobileNetV3Small and MobileNetV3Large to get the best model. The results showed that the MobileNetV3Small architecture produced the best model at batch size 32 and the number of epochs 30 with an accuracy of 98.81% for testing data.

Abstract

Ownership of weapons throughout the world, especially firearms, is increasing sharply, giving rise to problems in terms of security and safety. The public must be aware of the risks and threats associated with the misuse of illegal weapons. That way, the public can have a better understanding of gun control and increase awareness of the dangers of violence and crime caused by weapons. The application that will be designed aims to apply Android-based Augmented Reality (AR) as a medium for military weapons education by getting to know various types of weapons and the dangers they pose by presenting more interesting and interactive information. The Augmented Reality (AR) method used in this application is the markerless and markerbase method. The markerless method does not require special markers to display virtual objects, making it possible for AR to be used anywhere. The markerbase method requires an image medium (marker) to display virtual objects by recognizing the position and orientation of the marker. Application Programming Interface (API) allows applications to communicate efficiently and easily with other applications via the Web Dashboard. By using API, it can be easy to update the content of military weapons information databases and quizzes automatically via an internet connection. In this research, the Multimedia Development Life Cycle (MDLC) approach was used as the method to be applied. By considering the results of testing that has been carried out through black box testing, angle testing, distance testing, and light intensity testing, it shows that the designed application can run well according to the expected goals, namely as an interactive educational medium that attracts various types of weapons and the dangers they cause. .

Abstract

To accommodate large amounts of data, a structured data warehouse is needed to produce more accurate information and support decision making for organizational stakeholders. To build a data warehouse, software such as Microsoft SQL Server can be used which has advantages in the aspects of data security, scalability, collaborative capabilities and extendability. Serial data on population, health personnel, economics and various continuous primary and secondary data can be uploaded into SQL Server so that it can be stored in a structured and periodic manner. Data stored in the database is processed using certain data mining algorithms to produce information, knowledge and wisdom. This data warehouse and data mining approach can be applied to various sectors, for example health. This research aims to apply a data warehouse and data mining approach to analyzing the ratio of health worker needs in West Java Province, Indonesia using a single moving average algorithm and semi-automatic classification using empirical statistics on SQL Server and SQL Server Agent as well as visualization using Microsoft Power BI. Classification based on forecasting analysis of population data and determining the health worker gap ratio was successful in finding patterns through data mining on SQL Server efficiently and easily visualized using Power BI. Thus, SQL Server can be one of the practical tools chosen for implementing sustainable data mining.

Abstract

Applications of artificial intelligence, such as Chat-GPT and Bard, have become common in various aspects of life today. One of the main aspects is the use of the Question Answering (QA) model to meet specific domain needs. However, in some cases, models like Bard may not be able to provide specific information, such as registration procedures at a particular company or lecturer schedules at a university. To overcome this challenge, an Indonesian QA model called IndoBERT-QA has been developed. This research aims to evaluate the capabilities of IndoBERT-QA in a specific domain context using the Mean Reciprocal Rank (MRR) evaluation method. The evaluation results show that the IndoBERT-QA model is able to achieve an MRR of 0.91 with an approach to creating a customized context for each question. These results indicate that this model has good performance in providing relevant answers. The benefit of this research is that it serves as a valuable reference for the development of QA systems that will be created by other parties in the same environment. By utilizing a well-tested and evaluated approach, this research provides a strong foundation for the development of a high-performance QA system in Indonesian, so that it can meet domain-specific needs. Besides that, this research also provides insights for further development. One approach that can be explored is the use of Information Retrieval or Passage Retrieval as an initial step in the QA process. This can help the model in getting more precise and relevant context, thereby allowing further improvement in the quality of the answers provided by the model.
