Abstract

The rapid proliferation of digital communication has exponentially increased the volume of Short Message Service (SMS) spam, exposing mobile users to systemic convenience disruptions, productivity drops, and severe financial losses through sophisticated fraudulent schemes. To construct a highly dependable filtering mechanism, this study presents a rigorous dual-pipeline machine learning framework that systematically addresses the challenges of class imbalance in statistical text mining. Utilizing a verified dataset of 5,572 Indonesian-context short messages, the raw textual corpus is subjected to uniform case normalization, structural URL extraction, and character filtering before feature projection via Term Frequency–Inverse Document Frequency (TF-IDF) vectorization. To overcome the inherent accuracy paradox of skewed class distributions, the experimental design evaluates a baseline pipeline (imbalanced data) against a synthetic data augmentation pipeline leveraging the Synthetic Minority Oversampling Technique (SMOTE) across four distinct classifiers: Logistic Regression, Naive Bayes, Linear Support Vector Machine (Linear SVM), and Random Forest. Empirical results demonstrate that while the baseline Linear SVM serves as the optimal standalone model for overall balance, achieving a peak accuracy of 98.11% and a dominant F1-Score of 92.83%, the SMOTE-augmented Random Forest configuration yields an exceptional high-security alternative by securing a flawless 100.00% precision envelope alongside an 83.89% recall rate. Advanced post-hoc evaluations including McNemar's statistical significance tests (,  for Random Forest), qualitative error analyses of semantic edge cases, and runtime profiling confirm that the developed architecture establishes a highly scalable, mathematically verified, and low-latency solution suitable for integration into real-time telecom filtering gateways.

Abstract

The National Zakat Amil Institutions (LAZNAS) play a vital role in Indonesia's zakat ecosystem as independent non-governmental organizations connecting muzakki with beneficiaries nationwide, and official websites have become a primary medium through which they communicate identity, programs, and fund management accountability to the public. This study examines digital disclosure patterns across all 15 nationally licensed LAZNAS websites through qualitative content analysis conducted in June 2026, using a five-dimensional rubric adapted from global NPO web disclosure frameworks and enriched with Islamic accountability principles. Findings reveal considerable variation across dimensions and websites, with program reporting the most consistent and financial transparency the most varied. A fund efficiency summary is not yet explicitly available on any website in the sample, reflecting the absence of sectoral norms or regulatory provisions encouraging this type of public digital disclosure, and more than half of the websites face technical barriers that limit public accessibility. The study proposes technical website accessibility as a distinct analytical dimension in Islamic philanthropy web disclosure research and identifies innovative practices with potential for broader sectoral adoption.

Permasalahan utama yang dihadapi mitra adalah belum tersedia katalog produk digital dan website yang dapat digunakan sebagai media branding dan promosi usaha, sehingga pemasaran masih dilakukan secara konvensional melalui penjualan langsung dan komunikasi personal melalui WhatsApp. Kegiatan ini bertujuan meningkatkan kapasitas digital mitra melalui pelatihan pengembangan katalog produk digital berbasis website menggunakan Google Sites. Kegiatan melibatkan empat peserta yang terdiri atas satu orang pemilik usaha dan tiga karyawan. Kegiatan dilaksanakan melalui beberapa tahapan, yaitu sosialisasi, pelatihan branding dan pemasaran digital, pelatihan pengelolaan Google Sites, penerapan teknologi, serta pendampingan dan evaluasi. Hasil kegiatan berupa website katalog produk yang memuat profil usaha, katalog produk, dan informasi kontak yang terhubung dengan WhatsApp. Selama pendampingan, mitra berhasil menambahkan 15 produk ke dalam katalog secara mandiri. Mitra juga telah mampu melakukan pengelolaan dan pembaruan informasi produk pada website. Dengan adanya website katalog tersebut, mitra memiliki media promosi digital yang dapat dikelola secara mandiri untuk mendukung pemasaran produk UMKM. Kata kunci: UMKM; katalog digital; google sites; pemasaran digital; pelatihan Abstract Tata Production, a bead-based craft business, is an MSME located in Gudo District, Jombang Regency, specializing in accessories made from self-crafted beads derived from recycled bottles. The primary challenge facing the partner was the absence of a digital product catalog or website to serve as a platform for branding and promotion; consequently, marketing relied on conventional methods such as direct sales and personal communication via WhatsApp. This initiative aimed to enhance the partner's digital capabilities through training on developing a website-based product catalog using Google Sites. Four participants is the business owner and three employees took part in the program. The activities were conducted in several stages: an initial briefing, training on branding and digital marketing, Google Sites management training, technology implementation, and ongoing mentoring and evaluation. The outcome was a product catalog website featuring the business profile, product listings, and contact information linked to WhatsApp. During the mentoring phase, the partner successfully added 15 products to the catalog independently and gained the ability to manage and update product information on the site. With this catalog website, the partner now possesses a digital promotional tool that can be managed independently to support the marketing of their MSME products. Keywords: SME; digital catalog; google sites; digital marketing; training
