Abstract

Penelitian ini bertujuan untuk mengidentifikasi dan mendeskripsikan keanekaragaman dan potensi tumbuhan obat yang terdapat di wilayah kampus Universitas Samudra. Metode yang digunakan dalam penelitian ini meliputi eksplorasi lapangan langsung dan telaah pustaka untuk mengetahui manfaat dan bagian tumbuhan yang umum dimanfaatkan sebagai obat. Hasil penelitian mencatat 27 jenis tumbuhan obat dengan jumlah individu tumbuhan sebanyak 1.676 individu. Jenis tumbuhan yang paling dominan adalah Rhoeo discolor sebanyak 763 individu. Bagian tumbuhan yang paling sering dimanfaatkan adalah daun (63,89%), diikuti bunga dan buah. Penyakit yang paling sering diobati adalah batuk (18,18%), hipertensi (10,91%), serta demam dan luka (masing-masing 7,27%). Nilai indeks keanekaragaman Shannon-Wiener sebesar 2,15 menunjukkan tingkat keanekaragaman jenis sedang. Temuan ini menunjukkan bahwa wilayah kampus memiliki potensi yang signifikan sebagai sumber tumbuhan obat untuk pengembangan obat herbal berbasis lokal. Selain itu, hasil penelitian ini berfungsi sebagai referensi ilmiah yang berharga untuk pendidikan, pelestarian lingkungan, pengembangan kebun obat kampus, dan pelestarian pengetahuan tradisional.

Abstract

Stomata are openings in the epidermis that are lined by two special epidermal cells known as guard cells. In sugarcane (Saccharum officinarum) leaves, stomata are found on both the upper (adaxial) and lower (abaxial) surfaces, making them amphistomatous. Stomata are classified into several types, including anomocytic, anisocytic, and parasitic. Studies on the structure of stomata in plants of the genus Saccharum are still limited. This study aims to provide scientific information about the types of stomata in Saccharum plants. This study was carried out from October to November 2023 at the biology laboratory. Qualitative descriptive method with the type of stomata considered under the microscope. Data collection techniques using observation. The results of this investigation show that the genus Saccharum has Graminae type stomata, guard cells shaped like a halter. Stomata size in sugarcane species is generally larger than in barnyard grass species.

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.
