Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kemandirian ekonomi ibu rumah tangga melalui pelatihan dan pendampingan usaha berbasis potensi lokal di Kampung Keganteran. Program dilaksanakan dengan pendekatan berbasis riset melalui tahapan observasi awal, identifikasi kebutuhan, analisis potensi lokal, pelatihan teknis, pembentukan kelompok usaha, serta evaluasi hasil kegiatan. Pelatihan meliputi penyuluhan kewirausahaan, praktik produksi keripik pisang dan keripik bawang, pengemasan, serta strategi pemasaran sederhana. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan dan keterampilan peserta sebesar 65% berdasarkan hasil pre-test dan post-test. Sebanyak 83% produk yang dihasilkan telah memenuhi standar mutu dasar, meliputi tekstur renyah, warna merata, dan kemasan yang rapi. Selain itu, terbentuk kelompok usaha yang mampu membagi peran produksi dan mulai melakukan pemasaran melalui sistem titip jual di warung sekitar. Program ini juga berdampak pada meningkatnya kepercayaan diri, motivasi berwirausaha, serta inisiatif pengembangan produk lanjutan. Dengan demikian, pelatihan dan pendampingan usaha berbasis potensi lokal terbukti efektif dalam meningkatkan keterampilan teknis, kemampuan manajerial, serta memperkuat kolaborasi kelompok sebagai upaya mendukung keberlanjutan usaha pangan lokal masyarakat.

Abstract

This study addresses university students’ persistent difficulties in developing geometrical thinking, defined as the ability to interpret slopes, understand tangent behavior, and coordinate graphical and symbolic representations, when learning derivative concepts. The study investigates changes in students’ geometrical thinking following instruction supported by graphic visualization. A one-group pretest–posttest quasi-experimental design was conducted with 30 students in mathematics education, limiting causal inference due to the absence of a control group. Data were collected using a six-item open-ended geometrical thinking test and structured classroom observations, which served as triangulation. The results showed significant improvement after the visualization-based instruction. The average pretest score increased from 48.12 to 67.51, with a normalized gain (N-gain) of 0.39, indicating moderate improvement. A paired-sample t-test confirmed a statistically significant difference (p < 0.001). Although the effect size was large (d = 4.17), this finding should be interpreted cautiously given the study design and sample size. Observation data supported these results by revealing improved graphical reasoning, representational coordination, and student engagement. These findings indicate the potential of graphic visualization to support students’ geometrical thinking in derivative learning, rather than to demonstrate definitive instructional effectiveness.
