Abstract

Fakta menunjukkan kesulitan dalam belajar geometri di universitas yaitu kesulitan menentukan fungsi Trigonometri untuk sudut negatif atau lebih besar dari 90 derajat, dan kesulitan menerjemahkan beberapa representasi fungsi Trigonometri. Masalah yang melibatkan kemampuan berpikir Trigonometri dapat diselesaikan dengan menampilkan perekayasaan informasi gambar, diagram atau animasi. Salah satu media dengan yang dapat menstimulasi berpikir Trigonometri adalah PhET Simulation. Media digital dapat menunjukkan performa yang lebih baik jika didukung lembar kerja untuk memandu proses pengikatan ilmu pengetahuan. Tujuan penelitian ini adalah bagaimana proses perancangan worksheet yang mengintegrasikan pemanfaatan media interaktif Phet Simulation. Penelitian pengembangan dijadikan sebagai pendekatan penelitian yang meliputi tiga bagian yakni problem and design solution analysis, product specification and development, serta prototype evaluation and limited test. Pengujian validator ahli memiliki indikasi bahwa lembar kerja yang dikembangkan memenuhi standar pengujian ahli untuk digunakan dalam menyelesaikan masalah Trigonometri. Pengujian terbatas pada subjek penelitian menunjukkan instrumen yang diuji memenuhi standar valid dan reliabel. The facts show that the difficulties in learning geometry at university was difficulty to determine Trigonometry functions for negative angles or greater than 90 degrees, and difficulty to translate some representations of Trigonometry functions. Problems involving Trigonometry thinking skills are most likely solved by presenting manipulated images, diagrams and animations. One media to stimulate Trigonometry thinking is PhET Simulation. Additionally, a digital media is believed to improve the performance if it is supported by worksheets to guide the knowledge construction process. Therefore, the purpose of the study was to investigate the designing process of integrating the use of interactive media Phet Simulation. Developmental research was used as the research approach encompassing three sections, namely problem and design solution analysis, product specification and development, and prototype evaluation and limited test. The expert validator tests indicated the worksheet developed met the requirement as a solution in solving Trigonometry problems. Limited test to the research subjects confirmed that the instruments were tested valid and reliable.

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

Trigonometry learning often presents challenges as students struggle to apply mathematical concepts in real-world contexts. Traditional instruction tends to emphasize procedural fluency over conceptual understanding, limiting the development of students’ adaptive thinking skills. Digital tools like PhET simulations offer interactive visualizations that support conceptual learning, but their role in enhancing adaptive thinking remains underexplored. This study investigates the comparative effectiveness of PhET-based worksheets versus traditional paper-based worksheets in fostering adaptive thinking in trigonometry. The study involved 80 first-year students from Universitas Serang Raya’s Mathematics Education and Informatics Engineering programs, enrolled in the 2023–2024 Calculus course. Participants were divided into an experimental group using PhET-based worksheets and a control group using paper-based worksheets. Data were collected through pre-tests, post-tests, and student preference questionnaires, and analyzed using independent t-tests. Results show that the PhET group outperformed the control group, with a 35% improvement in adaptive thinking skills versus 20% in the control group (p < 0.05). Students using PhET-based worksheets demonstrated greater flexibility in applying trigonometric concepts, creative problem-solving, and knowledge transfer to real-life situations. In contrast, the paper-based group showed moderate gains, particularly in structured and procedural problem-solving. Questionnaire responses revealed that students appreciated the interactivity and engagement of PhET-based media, while also valuing the focus and clarity offered by paper-based worksheets. These findings highlight the potential of a blended learning approach that combines digital interactivity with structured offline tasks to enhance adaptive thinking. Future research should explore the long-term effects and broader applications of such strategies in mathematics education.
