Abstract

Implementasi algoritma k-Nearest Neighbor Classifier dengan teknik Data Mining pada prediksi curah hujan dapat membantu mayoritas masyarakat di Kabupaten Bandung yang memiliki mata pencaharian di bidang pertanian. Himpunan data berasal dari BMKG (Badan Meteorologi, Klimatologi, dan Geofisika) Bandung dengan jangkauan waktu antara Januari 2005 hingga Desember 2016 yang terdiri dari enam atribut, yaitu: penyinaran matahari, kelembapan, angin, temperatur, uap dan curah hujan. Hasil pencarian tetangga terdekat adalah atribut curah hujan dari lima kategori kelas, yaitu: tidak hujan, hujan ringan, hujan sedang, hujan lebat dan hujan sangat lebat, yang dihitung menggunakan euclidean distance. Penelitian ini melakukan pengujian akurasi dengan tiga partisi himpunan data dan penggunaan sepuluh nilai k yang berbeda. Akurasi-akurasi yang didapatkan sangat baik dengan akurasi tertinggi sebesar 97,92% untuk nilai k={3,5} pada partisi himpunan data latih dan uji masing-masing 50%. Nilai k, jumlah himpunan data dan data latih berpengaruh dalam pencarian tetangga terdekat.

Abstract

This research was conducted to solve sales data collection problems in the digital marketing business at CV. Icommits Work Solutions. The problem that occurs is that the process of entering data is inefficient and still uses ineffective conventional methods. By doing this research the authors are looking for a way to solve this problem, and the way to solve it is to develop the Closing Register application. The purpose of developing the Closing Register application is to simplify the process of entering data and monitoring sales data so that consumers, customer service and CS admins do not need to expend a lot of energy in the sales data collection process. The Closing Register application is made with the RAD (Rapid Application Development) design model, as well as the technology used in application development, namely ReactJS as a framework in charge of creating web admin views, Flutter as a framework in charge of creating mobile displays, MySQL as a database, and ExpressJS as a framework whose job is to create an API (Application Programming Interface). The results showed that technologies are used to create up-to-date applications and for long-term use, so that later these applications can be used directly and are useful for digital marketing businesses.

Abstract

A strategic plan is an organization's detailed and extensive strategy to effectively manage its resources and achieve its goals within a specified period. Effective implementation of an information system necessitates strategic planning inside an organization to capitalize on the advantages of the information system implementation fully. This also applies to a Vocational High School in Cimahi. The school encounters many obstacles, including managing school data and performance assessments and requiring a unified system across departments to facilitate the school's operational procedures. Strategic planning establishes specific objectives, such as integrating information systems in academic and non-academic operations, overseeing school data management, enhancing infrastructure management efficiency, and boosting competitiveness by developing a web-based school support system for information and promotional purposes. Aligning the information system's strategies with the school's business strategies will aid in accomplishing these objectives. Developing information system strategies necessitates alignment with the organization's existing business strategies. This research examines the strategic information system planning process, specifically employing the Ward-Peppard technique. This approach facilitates a more comprehensive comprehension of the firm before developing a strategic plan. It involves doing a SWOT analysis, Value Chain analysis, Porter's Five Forces analysis, and McFarlan's strategic grid analysis as recommendations for the proposed information system strategies.
