Tujuan dari penelitian ini yakni mengetahui kesulitan siswa secara konseptual dan secara prosedural dalam pemecahan masalah matematis dalam keliling dan luas segitiga. Subjek berjumlah 28 siswa kelas IV SDN Jatibatur 3. Metode yang digunakan yakni deskriptif tipe cross sectional survey. Instrumen yang digunakan yakni tes kemampuan dasar dan tes diagnostik. Simpulan menyatakan bahwa kemampuan prosedural siswa terbagi menjadi dua kesalahan, kesalahan konsep perhitungan dengan persentase sebesar 63,33% dan kesalahan konsep keliling dan luas segitiga dengan persentase sebesar 58,33%. Kemampuan pemecahan masalah tertinggi yang dicapai siswa yakni tahap memahami masalah dengan persentase sebesar 53,7%, sedangkan kemampuan terendah yaitu tahap penafsiran solusi dengan persentase sebesar 10%.

Abstract

Shigella dysenteriae merupakan bakteri penyebab infeksi terutama di daerah saluran  pencernaan. Efek toksin yang dihasilkan menimbulkan diare yang encer dan muntah-muntah, lebih lanjut dihasilkan feses disertai nanah dan darah. Umumnya diare berdarah atau disentri dapat disembuhkan menggunakan antibiotik, namun penggunaan yang tidak tepat dapat menyebabkan resistensi. Pemanfaatan rimpang bangle (Zingiber purpureum Roxb), yang diketahui memiliki efek antibakteri, merupakan salah satu alternatif yang menjanjikan dalam mengatasi permasalahan resistensi bakteri. Penelitian ini bertujuan untuk mengetahui efektivitas antibakteri ekstrak etanol rimpang bangle terhadap bakteri penyebab diare berdarah atau disentri Shigella dysenteriae. Metode eksperimental digunakan sebagai metode difusi cakram dengan varian konsentrasi 25%, 50%, 75% dan 100%, Ciprofloxacin sebagai kontrol positif dan akuades sebagai kontrol negatif. Penelitian menunjukkan ekstrak rimpang bangle terdeteksi adanya senyawa alkaloid, flavonoid, fenol, dan tanin dengan diameter zona hambat yang dihasilkan sebesar 8,8 mm (25%), 12,8 mm (50%), 13,8 mm (75%), 14,3 mm (100%), dan 25,3 mm (ciprofloxacin). Adanya aktivitas antibakteri ekstrak etanol rimpang bangle (Zingiber purpureum Roxb) terhadap pertumbuhan Shigella dysenteriae.

Abstract

The development of digital technology offers significant opportunities for Micro, Small, and Medium Enterprises (MSMEs) to expand their market reach and enhance product competitiveness. However, many MSMEs still face challenges in effectively utilizing technology for marketing purposes. This study aims to design a marketing system based on the OpenCart platform tailored to the needs of three MSMEs in Agam Regency: Ay-la Goat Milk, 3 Saudara Nursery, and Nirwana Flower Studio. The research method applied in this study is Research and Development (R&D) with the ADDIE model approach, encompassing five stages: needs analysis, design, development, implementation, and evaluation. The findings indicate that the developed system effectively supports MSMEs in managing product marketing more efficiently, featuring product management, transaction processing, and promotional tools. The implementation of this system not only enhances MSME operational efficiency but also broadens their market access in the digital realm. Therefore, this research contributes positively to accelerating the digital transformation of MSMEs in Agam Regency.
