Abstract

The aim of this research is to reduce household organic waste through the use of organic waste as a natural detector of formaldehyde content in food snacks. The organic waste used in this study was red garlic skins, dragon fruit skins and purple sweet potato skins. This research is an experimental research. The stages of the research started with the extraction of anthocyanins from the three organic wastes, direct detection of formalin and detection of food ingredients. The formalin concentrations tested were 0.5%, 1%, 2%, 5% and 25%. Detection ability can be seen from the color change between control and formalin treatment. Garlic skin produces a red extract, dragon fruit skin produces an orange extract, and purple sweet potato skin produces a deep red extract. Test results on 20 samples of food snacks around the campus using the three organic waste extracts proved that all samples contained formaldehyde in varying concentrations. The highest 50% formalin content was found in yellow noodles and meatballs. The conclusion is that purple beetle skin, dragonfruit skin, and red garlic skin can be used as natural detectors for formalin in campus snacks.

Abstract

This study aims to produce learning media in the form of a Leafcapture Identification Application Based on Augmented Reality (AR) in plant morphology courses with accuracy, user interface, and good content. The research method used in this study is Research and Development (R&D) with the The ADDIE approach involves a systematic process for designing learning media. In the Analyze stage, the focus is on identifying the need for new learning media, specifically the Leafcapture Identification Application Based on AR, and assessing its feasibility and requirements. In the Design stage, activities include application design, interface design, 3D image creation, and marker design. The Development stage involves gathering relevant content, such as plant leaf images and names, and setting up the application interface. During Implementation, the developed media is used and evaluated by experts and users to assess its impact on learning quality. Media experts validated the product with a 75% approval rating, while subject matter experts found it 88.89% valid. Evaluation was conducted by surveying students in plant morphology courses, with results confirming the product's effectiveness. Through AR, students can directly engage with three-dimensional (3D) models of various parts of plants, such as roots, stems, leaves, flowers, and fruits. They can manipulate and examine each part more deeply, enhancing their understanding of the relationships between parts and the functions of each component. Additionally, AR makes learning plant morphology more engaging and lifelike.Keywords: Augmented Reality; biology; Leafcapture identification.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilatar belakangi oleh rendahnya keterampilan merancang eksperimen pada siswa SMP IT Syamsul Huda, yang disebabkan oleh dominasi praktikum verifikasi berbasis resep dalam pembelajaran biologi. Tujuan kegiatan ini adalah untuk meningkatkan keterampilan siswa dalam merancang eksperimen melalui pendampingan praktikum berbasis proyek. Metode yang digunakan meliputi ceramah, demonstrasi, dan pelatihan. Ceramah diberikan untuk menyampaikan konsep merancang eksperimen secara ilmiah, demonstrasi dilakukan untuk memperkenalkan teknik penggunaan alat dan bahan laboratorium, serta pelatihan dilaksanakan melalui praktikum berbasis proyek menggunakan Lembar Kerja Siswa (LKS) yang telah dirancang secara sistematis. Hasil kegiatan menunjukkan peningkatan kemampuan siswa dalam mengidentifikasi masalah, merumuskan hipotesis, merancang prosedur eksperimen, dan menarik kesimpulan ilmiah. Selain itu, respon siswa terhadap kegiatan ini sangat positif, dengan seluruh indikator kepuasan peserta berada pada kategori sangat baik. Kegiatan ini membuktikan bahwa pendampingan praktikum berbasis proyek efektif dalam mengembangkan keterampilan ilmiah siswa.
