Abstract

Transformasi digital di industri ritel menghasilkan akumulasi data pelanggan berskala besar yang memerlukan analisis cerdas untuk ekstraksi insight bernilai. Segmentasi tradisional berbasis demografi sering kali tidak memadai untuk menangkap kompleksitas perilaku konsumen modern. Penelitian ini bertujuan mengembangkan model segmentasi pelanggan supermarket yang akurat dan dapat ditindaklanjuti dengan mengintegrasikan teknik reduksi dimensi Principal Component Analysis (PCA) dan algoritma clustering K-Means. Metodologi yang diterapkan mencakup tahapan preprocessing data, reduksi dimensi dengan PCA, determinasi kluster optimal menggunakan pendekatan multi-metrik (Elbow Method, Silhouette Score, Davies-Bouldin Index), pelatihan model K-Means++, serta evaluasi dan interpretasi hasil. Dataset yang digunakan adalah Mall Customer Segmentation Data (200 sampel, 5 fitur). Hasil eksperimen menunjukkan bahwa integrasi PCA dan K-Means berhasil mengidentifikasi lima segmen pelanggan yang berbeda secara signifikan (p-value < 0.001) dengan karakteristik unik: The AffluentYouth (19.5%), The Budget-Conscious Middle-Aged (17.5%), The Moderate-Spending Seniors (11.0%), The High-Spending Low-Income Youth (22.0%), dan The Wealthy Savers (30.0%). Model mencapai Silhouette Score 0.55 dan Davies-Bouldin Index 0.71, menunjukkan kualitas clustering yang baik. Analisis komparatif mengungkap peningkatan kinerja sebesar 14.6% dibandingkan penerapan K-Means tanpa PCA. Temuan ini memberikan dasar berbasis data untuk strategi pemasaran terpersonalisasi, manajemen inventaris, dan pengembangan program loyalitas di supermarket.

Abstract

Kehadiran siswa merupakan indikator penting kedisiplinan dalam proses akademik. Di SMA IT Yapira, sistem pencatatan kehadiran saat ini masih dilakukan secara konvensional dengan memanggil nama siswa satu per satu (manual roll call). Metode ini sangat tidak efisien karena memakan waktu efektif pembelajaran, rawan kesalahan pencatatan, dan menyulitkan proses rekapitulasi data. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk merancang dan membangun sistem absensi berbasis barcode (QR Code) serta memberikan pelatihan penggunaannya kepada guru dan siswa. Metode pelaksanaan meliputi perancangan sistem selama tiga minggu dan pelatihan intensif selama satu hari. Hasil dari kegiatan ini adalah tersedianya sistem absensi digital yang memungkinkan pencatatan kehadiran secara instan melalui pemindaian kartu pelajar, menggantikan metode pemanggilan manual yang lambat. Penerapan sistem ini terbukti meningkatkan efisiensi waktu jam pelajaran dan validitas data absensi.

Abstract

This community service program aims to enhance the efficiency and productivity of hydroponic kale cultivation by leveraging the Internet of Things (IoT) technology. The activity partners are greenhouse managers in Beurawe Village, Kuta Alam District. The primary challenges faced by partners include limited monitoring tools for pH and EC levels of nutrient solutions, minimal technical expertise, and a lack of knowledge about plant nutrition and digital marketing. The solutions offered include training in the installation and use of an IoT System implemented using pH and TDS sensors connected to a Wemos D1 Mini microcontroller and displaying data in real-time through a digital dashboard, the preparation of a kale nutrient module, the implementation of a data-based automation system, and digital marketing training. This program is expected to increase the efficiency and productivity of hydroponics, especially in nutrient monitoring and control. Increasing the efficiency and productivity of hydroponics, especially in nutrient monitoring and control and being able to increase water use efficiency by up to 15%, reduce nutrient use by 20%, and increase plant productivity by 20%. This activity involves lecturers and students and supports MBKM policies and the development of sustainable technology-based precision agriculture in the community.

Abstract

Purpose: This community service initiative aims to assist Warung Kopi Pak Haji, a small-to medium-sized coffee establishment in Banda Aceh, by improving its cash management strategies and financial literacy competencies.  Methodology: Project case assignments, mentoring, and lectures were chosen to allow participants to feel that they were part of the decision-making process for their day-to-day operations. Additionally, it allows participants to gain and enhance their understanding of handling cash and finances. Results: The coffee shop's unique characteristic, financial unpredictability, necessitates the development of skills in cash management and strategic planning to ensure daily operations and reduce uncertainties. Cocnclusion: This community service program demonstrates that enhancing financial literacy and cash management skills is crucial for the sustainability of small and medium-sized enterprises. Through training, mentoring, and project-based learning, the coffee shop staff and owner gained practical knowledge of managing daily operations, planning future investments, and reducing financial uncertainty. These outcomes highlight the importance of continuous capacity building to strengthen SMEs’ resilience and promote long-term growth. Limitations: Long business hours, participants’ work schedules, and capabilities make constant participation in training exceedingly difficult for all employees. Contribution: This community service supports the financial capacity, entrepreneurship, and skills of small and medium-sized businesses, particularly focusing on enhancing cash management effectiveness and financial literacy in a small-to-medium coffee shop in Banda Aceh. Managing finances effectively for daily operations is essential for the success of SMEs.
