Abstract

Measuring the quality and health of water in a decorative fish tank can be simplified by regularly monitoring the water pH. However, this pH monitoring is often neglected by aquarium owners due to work commitments, household responsibilities, or when they have to leave home for an extended period of time. This research designed a water pH monitoring system in an ornamental fish aquarium using a pH sensor and an ESP-32 microcontroller that can remind users through a telegram Bot message and can be seen through the LCD using the waterfall development method as a method of making tools in this study. Based on the research that has been done, the automatic pH reading system has been successfully built by being accessed via telegram and can be seen on the LCD display. pH Sensor testing has an accuracy value of 90% with testing using litmus paper comparison.

Abstract

Tomkids Children's Clothing Store Bandung is a store engaged in the sale of children's clothing in Cimenyan-Bandung Regency. So far, activities in the store can be said to be less than optimal, because the transaction process is still carried out conventionally or buyers come directly to the Tomkids Store. This makes it difficult for customers who live far from the Tomkids Store. Customers find it difficult to find out what information is still offered by the Tomkids Store, therefore a website design is needed that can help increase sales at the Tomkids Store. The method used in designing a website at Toko Tomkids is using the Lean UX model based on the website. From the analysis and design process, a UI/UX E-commerce application will be produced at Toko Tomkids which can help in the promotion and sales process, and make it easier for customers to make online children's clothing purchases. And the data analysis and processing techniques use a questionnaire by giving statements to respondents. To reach respondents, 40 people were selected, consisting of two groups, the first is 20 respondents who are lay with e-commerce and experienced in online shopping. Second, there are 20 respondents who have or have a trading business. The results of this study are in the form of a better and optimal User Interface and User Experience design for the e-commerce application at Toko Tomkids Baju Anak Bandung based on the website. The purpose of designing this application is to display the interface and experience pages so that it can provide information to customers, make orders and also be able to make purchases so that customers can make transactions online.

Abstract

Evolusi teknologi digital memberikan efek yang baik sekaligus tantangan, terutama untuk remaja yang mudah terpengaruh oleh praktik taruhan online dan pinjaman online ilegal. Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk menggugah kesadaran dan pemahaman siswa SMK Assalaam tentang risiko judi online dan pinjaman online  yang tidak sah, serta mempromosikan perilaku cerdas dalam penggunaan internet. Metode pelaksanaan terdiri dari sosialisasi, pembahasan interaktif, penyajian studi kasus, dan distribusi materi edukasi. Peserta terdiri dari 100 siswa yang menjalani pre-test dan post-test untuk mengevaluasi peningkatan pengetahuan. Hasil evaluasi mengindikasikan peningkatan yang signifikan dalam pemahaman peserta tentang risiko finansial, hukum, dan psikologis terkait judi online dan karakteristik pinjaman online yang ilegal. Selain itu, peserta juga semakin kritis dalam merespons iklan dan penawaran pinjaman daring. Peran guru dan orang tua dalam mendukung remaja di era digital juga menjadi perhatian dalam kegiatan ini. Sebagai kesimpulan, sosialisasi ini efektif meningkatkan literasi digital siswa SMK Assalaam yang bertempat di Jl. Situ Tarate, Kelurahan Cangkuang Kulon, Kecamatan Dayeuhkolot, Kabupaten Bandung dengan tujuan untuk menghindari praktik berbahaya di dunia maya. Kegiatan ini diharapkan dapat menjadi contoh pendidikan digital untuk remaja di sekolah-sekolah lain.

Abstract

Transformasi digital pada pendidikan tinggi menuntut tata kelola sistem akademik yang terstandar dan terukur, namun banyak institusi menhadapi tantangan dalam dokumentasi formal dan standarisasi proses teknologi informasi. Penelitian ini bertujuan untuk mengaudit Sistem Informasi Akademik (SIAKAD) Universitas Kebangsaan Republik Indonesia (UKRI) menggunakan framework COBIT 2019 guna mengidentifikasi kesenjangan kapabilitas dan strategi perbaikan terstruktur. Penelitian menggunakan pendekatan kuantitatif dengan metode triangulasi, seperti observasi, wawancara, dan kuesioner, yang melibatkan 23 responden, diantaranya 4 internal stakeholder dan 19 mahasiswa. Berfokus pada enam subdomain, yaitu APO02, APO05, APO12, DSS04, MEA01, dan MEA03. Penilaian capability level menunjukkan seluruh subdomain berada pada level 1 – performed process dengan nilai rata-rata berkisar 3,4-4,0 dalam skala Likert (1-5), yang setelah triangulasi data mengonfirmasi proses telah berjalan namun belum terdokumentasi formal. Analisis gap menunjukkan kesenjangan 3 level antara kondisi aktual (level 1) dan target (level 4 – predictable process). Penelitian menghasilkan rekomendasi perbaikan komprehensif yang meliputi penyusunan dokumentasi formal, pembentukan sistem pengelolaan terstruktur, dan implementasi pengukuran kinerja berbasis data. Roadmap pengembangan lima tahun (2026-2030) dirancang melalui lima fase, yaitu Assessment dan Awareness, Dokumentasi dan Integrasi, Implementasi dan Uji Proses, Penetapan dan Integrasi Audit, serta Standarisasi dan Prediktabilitas. System blueprint memetakan transformasi dari kondisi as-is menuju kondisi to-be dengan strategi perbaikan spesifik untuk setiap subdomain. Penelitian ini memberikan kontribusi praktis berupa panduan terstruktur untuk meningkatkan kapabilitas SIAKAD UKRI dari level 1 ke level 4 dalam periode lima tahun, sekaligus menyediakan instrumen audit yang dapat direplikasi oleh institusi pendidikan tinggi lain untuk mewujudkan tata kelola sistem informasi akademik yang berkelanjutan dan terukur.
