Abstract

The development of digital payment systems has increasingly exposed elementary school students to electronic money cards, digital wallets, and QR-code payments through their families and everyday experiences. However, familiarity with payment technology is not always accompanied by an adequate understanding of digital balances, personal-data protection, and transaction security. This community service program aimed to improve elementary school students’ digital financial literacy through the introduction of electronic money and safe transaction practices. The program was conducted at SDN Margahayu XIII, Bekasi City, on June 15, 2026, involving 30 fifth-grade students. The program applied a Digital Financial Safety Lab model consisting of a diagnostic test, learning-station rotations, case-based games, balance-management exercises, confidential-information identification, and safe digital-transaction simulations. Evaluation was conducted using pre-tests and post-tests, student worksheets, performance assessments, and behavioral observations. The results showed that the students’ average digital financial literacy score increased from 48.2 in the pre-test to 88.3 in the post-test, representing an improvement of 40.1 points. The percentage of students achieving the minimum competency score increased from 13.3% to 93.3%, while 96.7% of participants demonstrated improved scores.

Abstract

Maraknya pinjol ilegal dan rendahnya literasi keuangan digital meningkatkan kerentanan remaja terhadap keputusan berutang yang impulsif dan risiko keamanan data. Penelitian ini bertujuan mengevaluasi efektivitas program Abdimas berbasis keterampilan keputusan “baca–hitung–cek sebelum klik setuju” dalam meningkatkan literasi keuangan digital, kemampuan deteksi pinjol ilegal, dan perilaku preventif pada remaja. Metode yang digunakan adalah kuantitatif dengan desain pra-eksperimen one-group pretest–posttest. Kegiatan dilaksanakan pada 2 Januari 2026 di Yayasan Rahmatan Lil Alamin JT Cab. Cibubur bekerja sama dengan ASOSIASI DOSEN MUDA INDONESIA(ADMI) dengan 25 peserta remaja. Data dikumpulkan menggunakan kuesioner pretest–posttest yang mengukur pemahaman komponen biaya dan risiko pinjaman, kemampuan menghitung total kewajiban, kemampuan mengenali red flags serta verifikasi legalitas, dan indikator perilaku keamanan digital (OTP, phishing, izin aplikasi), kemudian dianalisis secara deskriptif dan uji beda berpasangan. Hasil menunjukkan peningkatan literasi keuangan digital, peningkatan akurasi deteksi pinjol ilegal, serta penguatan perilaku preventif, terutama kebiasaan mengecek legalitas dan komitmen menjaga keamanan data pribadi. Implikasi penelitian menunjukkan bahwa model edukasi praktis berbasis simulasi dan checklist dapat direplikasi pada komunitas/sekolah untuk pencegahan pinjol ilegal dan penguatan perlindungan konsumen digital pada remaja. Orisinalitas penelitian terletak pada integrasi literasi pinjol (biaya–risiko–legalitas) dengan literasi keamanan digital dalam satu alur tindakan yang operasional dan dievaluasi secara terukur melalui pretest–posttest pada konteks pengabdian masyarakat.

Abstract

Rice threshers and straw choppers are essential to improve post-harvest efficiency, yet small-scale machines often experience capacity loss and wasted motor power due to non-optimal V-belt–pulley transmission design (e.g., incorrect pulley ratio, belt length, and speed matching), which reduces speed stability and increases mechanical losses. Objective: This study aims to analyze and optimize the V-belt–pulley transmission system of a combined rice thresher–straw chopper to improve power utilization and achieve target operating speeds for both processes. Methodology: A quantitative engineering approach was applied using analytical transmission design calculations and design verification through mechanical layout/simulation. Key parameters were derived from machine requirements and transmission relations, including processing capacity, force and torque, shaft speed, power demand, pulley diameters, transmission ratios, belt speed, belt length, center distance, and wrap angle. Findings: Using a 1 HP (750 W), 1450 rpm electric motor, the designed system achieved a calculated threshing capacity of 90 kg/h and straw chopping capacity of 84 kg/h under a 2-minute batch assumption. The required output power was 270.60 W (threshing) and 245.97 W (chopping), while the motor-side power demand was 308.27 W and 280.30 W, respectively, resulting in a total requirement of 588.57 W (≈78% motor power utilization). With an 80 mm driver pulley, the selected driven pulleys were 105.45 mm for the thresher (1100 rpm; ratio 1.32) and 116 mm for the chopper (1000 rpm; ratio 1.45). The belt speed was 6.06 m/s, with belt lengths of 2110 mm (A83) and 1480 mm (A58). Implications: The results provide practical parameter benchmarks for designing low-cost small-scale agricultural machines that better match motor power to required speeds and torque, reducing transmission mismatch. Originality: This study presents a parameter-complete V-belt–pulley design framework for a dual-function thresher–chopper, explicitly linking capacity targets to transmission sizing and motor power utilization.
