Abstract

Ergastic objects are one of the non-protoplasmic components besides vacuoles. Ergastic objects in protoplasts can be solid and liquid.The purpose of the study was to determine how the structure and type of ergastic substances in plants of order poales. This research method includes descriptive research that describes the type and structure of ergastic substances in plants of order poales, the parts observed are bulbs, grains, stems to fruits that contain ergasticsubstances.Based on the results of research on the order of poales found that the order of poales has a diverse type of solid ergastics, such as amylum (starch) found in teapot grass plants (Cyperus rotundus), rice (Oryza sativa) and corn (Zea mays) with various shapes and types, there are also types of ergastic substances in the form of ca-oxalate crystals found in pineapple plants (Ananas comusus) and types of sugar-shaped egastic substances in sugar cane plants (Saccharum officinarum Linn).

Abstract

This study was motivated by the essential ecological role of macroscopic fungi in maintaining forest ecosystem balance and the lack of biodiversity data in the Protected Forest of Langsa City. The aim of this research was to identify and describe the morphological characteristics of macroscopic fungi and to assess their species diversity as a basis for scientific information. An exploratory survey method was used with direct field observation; sampling was conducted by exploring the forest area, and fungal identification was based on morphological characteristics such as cap shape, color, surface texture, lamella structure, attachment of the fruiting body, and habitat. The results showed that 15 species of macroscopic fungi were found, including Pycnoporus sanguineus, Ganoderma applanatum, Microporus xanthopus, and others, which were found growing on various substrates such as dead wood, soil, and animal dung. The observed cap shapes ranged from semicircular, fan-shaped, and umbrella-like to irregular oval, with diverse colors and textures. These findings indicate a high potential for fungal biodiversity in the area. This research provides essential baseline data to support conservation efforts and can be utilized for further exploration in pharmaceutical, food, and environmental education fields sustainably.

Abstract

Pesatnya perkembangan teknologi dalam dunia pendidikan menuntut inovasi media pembelajaran yang mampu meningkatkan pemahaman dan keterlibatan siswa. Salah satu materi yang memerlukan pendekatan visual dan interaktif adalah sistem pencernaan manusia di kelas XI SMA. Penelitian ini bertujuan untuk mengetahui tingkat validitas media pembelajaran berbasis flipbook, PowerPoint, dan games interaktif. Metode yang digunakan adalah penelitian dan pengembangan (R&D) dengan model 4-D (Define, Design, Develop, Disseminate), yang difokuskan hingga tahap develop. Subjek penelitian terdiri dari dua validator ahli, yakni ahli materi dan ahli media. Data diperoleh melalui lembar validasi dan dianalisis menggunakan skala Likert yang dimodifikasi. Hasil penelitian menunjukkan bahwa media flipbook memperoleh presentase validasi akhir sebesar 92% (materi) dan 94,6% (media), PowerPoint sebesar 90% (materi) dan 96% (media), sedangkan games memperoleh skor 88% (materi) dan 92,7% (media). Seluruh media dikategorikan sangat layak dan dapat digunakan tanpa revisi lebih lanjut. Pengembangan media flipbook, PowerPoint, dan games ini dinyatakan valid serta memiliki potensi besar dalam mendukung pembelajaran sistem pencernaan secara lebih efektif dan menyenangkan.
