Abstract

Pendidikan merupakan gerbang utama dalam memajukan suatu negara. UU SPN No. 20 Tahun 2003 Pasal 1, pendidikan adalah usaha sadar dan terencana untuk mewujudkan suasana belajar dan proses pembelajaran agar peserta didik secara aktif mengembangkan potensi dirinya khususnya pada SMK 12 Saentis. Permasalahan yang ada saat ini adalah masyarakat khususnya pelajar tingkat SMK khususnya pada SMK 12 Saentis yang telah menggunakan teknologi komputer ini tidak mengetahui atau mengenal Hardware atau komponen penyusun dari komputer tersebut yang menyebabkan mereka tidak dapat melakukan troubleshooting jika terjadi kerusakan pada hardware komputer, untuk mempelajari Hardware komputer dapat dengan menggunakan media-media seperti buku, tetapi cara ini dianggap kurang efektif, karena untuk mempelajari Hardware komputer diperlukan suatu alat peraga. Seperti halnya yang dilakukan di SMK 12 Saentis, mereka menggunakan Hardware komputer secara langsung sebagai alat peraga dalam pembelajaran mereka. Tetapi untuk melakukan hal itu tidak mudah, kita harus memiliki komputer atau laptop sendiri yang harus siap untuk menjadi bahan praktek yang sudah pasti memerlukan biaya yang tidak sedikit.

Abstract

Indonesia is one of the countries located in the Pacific Ring of Fire, where three tectonic plates meet. This makes Indonesia very vulnerable to natural disasters such as earthquakes, volcanic eruptions, and tsunamis. These natural phenomena occur very frequently, as evidenced by events such as those that have occurred on the island of Sumatra. This study aims to classify earthquake data in the Sumatra Islands based on hypocenter using the Naive Bayes Algorithm. The study uses earthquake datasets specifically from the Sumatra Islands, which are divided into training and testing data. The results of the study indicate that classification can be performed using the Naive Bayes Algorithm based on three categories, ranging from shallow earthquakes, moderate earthquakes, to deep earthquakes.

Abstract

The administrative and service division is in charge of handling and administering services that can be provided to the community at the Muara Kintap village hall. However, the public service data recording system is still manual by recording it in a book. This requires a lot of paper and of course requires a lot of budget and there is a risk of data loss, for example in the event of a fire, the book is tucked away, lost and so on. In this study, the authors built a system entitled Web-Based Muara Kintap Village Hall Service Documentation Application. This system aims to assist employees in recording community service data in a computerized manner, storing data safely using a database so that the data search process will also be easier. This system helps the public in submitting service requests easily online. The community can access the system, see what types of services are available and can submit requests for services by filling out form data through the system without having to come to the Muara Kintap village hall. The system development model uses the waterfall model. This system was built using a web-based software development approach using a MySQL database. The designs used are Entity Relationship Diagram (ERD) and Unified Modeling Language (UML). The programming language used is Hypertext Preprocessor (PHP) and the framework used is codeigniter 3. System testing using blackbox testing shows that all system functionality can run well and as expected by 100%.

Abstract

The government continues to encourage the government to accelerate Small and Medium Enterprises (SMEs) flagship products to enter the digital market, because the current digitalization of SMEs cannot be ignored, SMEs must be able to change their business to the digital realm. The strategy for developing superior SME products needs to be well planned, because a good and measurable strategy is very important for policy making. Development uses an approach that emphasizes that the driving force of development is commodities that are considered to be superior, both at the domestic, national and international levels. Superior products that have quality and are needed by customers require the right selection process, so we need a method to produce this information. Business Intelligence (BI) is a global term for all processes, techniques, and tools that support business decision making based on information technology. The strategy for developing superior products for SME products uses the criteria of production data, income, and SME respondent data in determining the priority list. A good product assessment based on priority can be done by BI using the classification method with the Support Vector Machine (SVM) algorithm. The research method carried out for planning the development of superior products for MSMEs in Tasikmalaya City is a research development research. To complete the classification of the right superior product development strategy, then Support Vector Machine algorithm can be used with test results using the Confusion Matrix with an average accuracy of 97%.
