Abstract

This PKM activity was carried out to support the marketing digitization process at Karunia MSMEs located in South Tegal District. These MSMEs previously conducted traditional marketing without utilizing sufficient digital technology. Through this program, the implementation team provided intensive assistance for 12 weeks with a focus on developing digital promotional media in the form of a WordPress-based website, as well as business visual identity design in the form of logos and banners. In addition, training on the basics of digital marketing and social media optimization was also delivered to improve the ability of business actors to manage promotions independently. The results of this activity include the creation of digital tools that can expand market reach, strengthen brand image, and increase the competitiveness of MSMEs in the digital transformation era. It is expected that the results obtained can make a sustainable contribution in supporting business growth and strengthening the presence of local products in a wider market. This program also opens up opportunities for collaboration between businesses and digital communities in the future.

Abstract

Penelitian ini bertujuan menghadirkan proctoring ujian daring yang ringan dan menjaga privasi dengan memindahkan seluruh inferensi ke sisi klien, menjawab masalah integritas ujian berbasis web yang kerap mengandalkan perekaman/unggah video server-side berbiaya dan berisiko. Kami membangun prototipe berbasis TensorFlow.js dan BlazeFace (single-stage CNN) yang menggabungkan kebijakan safe-area terkonfigurasi, adaptive screen-lock berbasis state machine, serta heuristik client-side anti-cheat; evaluasi dilakukan pada dataset beranotasi (offline) dan simulasi CBT in-situ (3×20 menit, perangkat heterogen), dengan metrik deteksi (AP/mAP, F1), kepatuhan safe-area, dan kinerja runtime. Hasil menunjukkan AP@0,5 sebesar 0,95 (pencahayaan normal), 0,91 (low-light), dan 0,93 (variasi pose), mAP@[0,5:0,95] masing-masing 0,66/0,59/0,61, serta F1 0,92/0,87/0,90; safe-area compliance median mencapai 0,86/0,92/0,95 pada perangkat rendah/menengah/tinggi; profil kinerja berada pada 22–48 FPS dengan latensi ujung-ke-ujung 28–58 ms; dan skor penerimaan privasi 4,5/5 (Likert). Kebaruan utama terletak pada integrasi utuh on-device single-stage CNN, kebijakan safe-area, adaptive screen-lock, dan metrik baru safe-area compliance ke dalam proctoring murni-peramban yang plug-and-play dan minim paparan data. Nilai praktisnya adalah penegakan integritas mendekati waktu nyata tanpa perekaman video; sementara keterbatasan mencakup penurunan recall pada low-light/occlusion dan belum adanya liveness lanjut, yang membuka arah riset untuk liveness/fairness, auto-tuning berbasis perangkat, dan uji lapangan berskala besar.

Abstract

Penelitian ini bertujuan untuk mengembangkan sistem prediksi instrumen finansial yang inovatif menggunakan pendekatan algoritma Information Retrieval. Dalam era digitalisasi pasar keuangan yang semakin kompleks, investor membutuhkan alat bantu pengambilan keputusan yang akurat dan berbasis data. Tiga metode yang dibandingkan adalah Term Frequency-Inverse Document Frequency (TF-IDF), Best Matching 25 (BM25), dan Cosine Similarity. Data dikumpulkan dari Yahoo Finance mencakup 18 instrumen finansial dari berbagai kelas aset termasuk saham teknologi Amerika Serikat, saham blue chip Indonesia, Exchange Traded Funds, dan mata uang kripto. Metodologi penelitian merepresentasikan setiap instrumen sebagai dokumen tekstual berdasarkan indikator teknikal. Hasil penelitian menunjukkan ketiga metode memiliki korelasi peringkat tinggi dengan Spearman Correlation di atas 0.94. Metode BM25 memberikan performa terbaik dengan NDCG sebesar 0.8756 dan MAP sebesar 0.8124. Instrumen yang diprediksi mengalami kenaikan meliputi NVIDIA, AMD, Bitcoin, Amazon, dan Microsoft.

Abstract

Mas Andi Red Brick Store in Bengle Village faces marketing challenges due to its continued reliance on conventional methods such as direct promotion and face-to-face sales. This strategy is considered less effective in today’s digital era, where consumers are more active in using online platforms to search for information and make purchases. To address this issue, a Community Service Program (PKM) was carried out with the aim of helping the business partner develop their enterprise through the implementation of digital marketing strategies to increase sales.The PKM activities were conducted in several stages, including initial observation, website usage training, intensive mentoring, and direct implementation of digital strategies. The training materials included the creation of social media accounts such as Instagram and Facebook, the development of promotional content, and the management of digital interactions with consumers. This was done because many potential customers search for red brick products via social media platforms.The results of this activity show that the business partner has started to understand the importance of digital marketing. The partner is now able to independently create and upload promotional content and expand their market reach through digital means. This activity not only improved their technical skills but also encouraged a change in mindset regarding the consistent use of digital technology to build a business image.The close collaboration between the service team and the partner created a participatory and practical learning environment. It is hoped that the skills gained can continue to be developed, allowing the partner’s business to grow and compete in an increasingly digital marketplace
