PT. Dian Fajar Cahaya Gemilang is a company engaged in the sale of medical equipment. To improve the quality of service to consumers, the company is required to be able to overcome problems that often arise, including changes in order requests for certain products so that the company cannot provide product stock quickly and accurately. Lack of stock in a company will have a very negative impact on the success and smoothness of sales and purchase transactions. This can be caused by customer sales patterns that are always changing and cannot be predicted. This study implements data mining using the apriori algorithm stage to find valuable information in the form of purchasing patterns by customers by utilizing the large amount of sales transaction data so that the company can prepare stock quickly and accurately to prevent accumulation and lack of product storage that will later result in losses.

Gangguan pencernaan pada anak merupakan masalah kesehatan serius di seluruh dunia, dengan diare menjadi penyebab utama kematian balita. Di Kota Batam, tingginya insiden diare akut dan gangguan pencernaan lainnya pada anak-anak menggarisbawahi urgensi untuk penanganan yang lebih baik. Faktor-faktor yang berkontribusi meliputi sistem kekebalan tubuh yang belum matang, pola makan yang tidak sehat, sanitasi yang buruk, rendahnya pemahaman orang tua tentang Perilaku Hidup Bersih dan Sehat, serta terbatasnya akses terhadap informasi dan fasilitas medis. Masalah ini semakin diperparah oleh gejala gangguan pencernaan yang tumpang tindih, sehingga menyulitkan diagnosis dini.
Untuk mengatasi tantangan ini, penelitian ini bertujuan untuk merancang dan membangun aplikasi sistem pakar berbasis web yang mampu mendeteksi gangguan pencernaan pada anak-anak. Sistem ini menerapkan metode Rule-Based Reasing dengan algoritma Forward Chaining, yang secara logis mencocokkan gejala yang dimasukkan pengguna dengan aturan dalam basis pengetahuan ini untuk menghasilkan diagnosis awal yang cepat. Aplikasi ini berfokus pada tiga indikator utama gangguan pencernaan: Diare, Konstipasi, dan GERD, untuk anak usia 5 bulan hingga 12 tahun. Dengan demikian, sistem pakar ini diharapkan dapat menjadi sarana interaktif yang dapat meningkatkan pemahaman orang tua, memudahkan dalam mendiagnosis gangguan pencernaan pada anak sejak dini, serta menjadi referensi bagi tenaga kesehatan dan pengembangan sistem informasi kesehatan.

Learning to read the Qur'an is a fundamental aspect of early Islamic education for children, with the Iqro’ method being one of the most widely adopted approaches in Indonesia. However, conventional implementations often lack engaging delivery, making it less appealing to young learners. In the digital era, with the increasing exposure of children to gadgets, there is a growing need for interactive educational media tailored to their characteristics. This study aims to develop an educational game application based on Construct 2 as a supplementary tool for teaching Iqro’ reading skills to first-grade students at SD IT Al-Jauharotunnaqiyah Ciajeng. The application presents Iqro’ Volume 1 content interactively, equipped with audio pronunciation, quizzes, writing simulations, and real-time visual and audio feedback. Implementation results show that the application meets both functional and non-functional requirements, and black box testing confirms that all features operate as expected. This application is deemed suitable as an enjoyable and effective self-learning tool, with the potential to shift children's screen time towards productive and religious activities.

The issue of waste accumulation has become a critical environmental concern that requires early educational intervention. Conventional waste education methods in elementary schools are often ineffective in fostering students' awareness and behavioral change. This study aims to design and develop an interactive educational game using Construct 2 and the Multimedia Development Life Cycle (MDLC) framework to enhance elementary students’ understanding of waste types, including organic, inorganic, and hazardous (B3) waste. The game, titled "Saving the Earth from Waste", adopts an educational adventure genre, integrating storyline, challenges, and reward systems to provide an engaging and meaningful learning experience. Validation results from teachers and parents indicated positive responses regarding the game’s interface, navigation, and educational content. The game is distributed in .apk format for easy access and installation and is considered suitable as a learning media for environmental education at the elementary level. The main contribution of this research is the provision of an effective, interactive, and contextual adventure-based educational game to support environmental education for young learners.

Proses seleksi siswa berprestasi di SMK TI Bali Global Singaraja menghadapi tantangan terkait objektivitas, terutama ketika dihadapkan pada beberapa kandidat dengan kualifikasi yang tampak setara. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sebuah Sistem Pendukung Keputusan (SPK) berbasis web guna memitigasi subjektivitas dan meningkatkan transparansi dalam proses pengambilan keputusan. Pengembangan sistem mengadopsi kerangka kerja Software Development Life Cycle (SDLC) dan mengintegrasikan model hibrida Multi-Criteria Decision-Making (MCDM). Metode Pivot Pair-wise Relative Criteria Importance Assessment (PIPRECIA) diaplikasikan untuk menentukan bobot dari tujuh kriteria penilaian yang telah diidentifikasi, berdasarkan masukan dari lima orang pengambil keputusan. Selanjutnya, metode Measurement of Alternatives and Ranking according to Compromise Solution (MARCOS) digunakan untuk melakukan perangkingan terhadap 73 alternatif siswa. Hasil penelitian menunjukkan bahwa SPK yang dikembangkan berhasil diimplementasikan secara fungsional, yang divalidasi melalui pengujian black-box dengan tingkat keberhasilan 100%. Selain itu, evaluasi kebergunaan melalui kuesioner System Usability Scale (SUS) menghasilkan skor rata-rata 75, yang mengindikasikan sistem dapat diterima dengan baik oleh pengguna akhir. Kombinasi metode PIPRECIA-MARCOS terbukti efektif dalam memberikan rekomendasi peringkat yang terstruktur dan dapat dipertanggungjawabkan.
