Abstract

Vertebrates is a type of animal that has a spine or backbone. Vertebrates are members of the phylum chordata and are bilateral animals (bilateral symmetry).This research aims to identify vertebrate species in the Langsa City Protected Forest which functions as ecotourism. In this research, the Exploration method using direct observation in the field has been analyzed descriptively. The research produced data that there were 22 vertebrate species in the Langsa City Protected Forest. Of the 22 species of vertebrates that are most protected in captivity, there are 3 species from the Acciptriformes order, 3 species from the Artiodactyla order. The results of this study are expected to provide information on the diversity of Vertebrata in the area of Langsa City Protected Forest that is used as an ecosystem.

Abstract

Starch is a type of polysaccharide formed from the polymerization of glucose. Starch is also known as starch which is a widespread reserve polysaccharide in plants. Starch is also defined as a complex carbohydrate which is very important as a food source. The purpose of this research is to determine the shape and type of starch in the tuber family. This research was conducted using descriptive methods. The purpose of this study is to describe and describe the characteristics of the forms and types of starch.Based on the results of observations, it can be concluded that the starch in taro, cassava, porang and jicama tubers has a concentric type and has regular and irregular round shapes, while potato tubers have an eccentric type and are oval or oblong in shape.Potato tubers have the highest starch of the five tubers because potatoes have a dense starch structure and contain a lot of starch or starch.

Abstract

Chlorophyll is the primary pigment in plants. Most chlorophyll is found in leaves, and its content varies among different leaves. Chlorophyll functions as an antioxidant for the body. Plants rich in chlorophyll include spinach and lettuce. Spinach and lettuce are popular vegetables among the public due to their high nutritional value. This study aims to determine the differences in chlorophyll content between these two types of vegetables. The research was conducted in the Basic Laboratory of Universitas Samudra using a spectrophotometer to identify the chlorophyll content in lettuce and spinach, determined through calculation methods. The results showed a significant difference in chlorophyll content between spinach and lettuce, particularly between green and red varieties. Green spinach had the highest chlorophyll content, whereas red lettuce had the lowest. This difference is due to pigment variations, where chlorophyll is more dominant in green varieties, while anthocyanin is more dominant in red varieties. Chlorophyll extracts from these vegetables have great potential as a natural antioxidant source that supports overall health, making them an important part of a daily diet.

Abstract

Penelitian ini bertujuan untuk menginventarisasi dan mengidentifikasi jenis-jenis tumbuhan Angiospermae di Universitas Samudra, Aceh, serta untuk memahami distribusinya dan potensi manfaatnya. Metode penelitian yang digunakan adalah pendekatan eksploratif-deskriptif dengan metode campuran (mixed methods), meliputi pengumpulan data kualitatif dan kuantitatif melalui observasi langsung dan identifikasi morfologi.Hasil penelitian menunjukkan terdapat 8 famili dan 14 spesies Angiospermae di Universitas Samudra. Famili Arecaceae (Palmae) memiliki jumlah spesies terbanyak, dan spesies Polyalthia longifolia (Glodokan Tiang) memiliki jumlah individu terbanyak. Keanekaragaman spesies yang ditemukan relatif rendah dibandingkan dengan penelitian serupa di kampus lain. Studi ini memberikan dasar informasi untuk pengelolaan lingkungan kampus yang lebih baik dan berkelanjutan.

Abstract

Motivasi dan hasil belajar merupakan faktor penting yang menentukan keberhasilan proses pembelajaran. Namun, proses pembelajaran IPA di SMP Negeri 2 Tanjung Pura masih didominasi metode ceramah dengan penggunaan media yang kurang variatif sehingga siswa cenderung pasif, kurang termotivasi, dan hasil belajar belum optimal. Penelitian ini bertujuan mengetahui pengaruh penerapan multimedia interaktif terhadap motivasi dan hasil belajar siswa pada materi sistem pencernaan manusia. Penelitian menggunakan pendekatan kuantitatif dengan metode quasi experiment melalui desain Nonequivalent Control Group Design. Sampel penelitian terdiri atas 32 siswa kelas eksperimen dan 30 siswa kelas kontrol. Pengumpulan data dilakukan menggunakan angket motivasi belajar serta tes pretest dan posttest hasil belajar. Data dianalisis menggunakan Independent Sample t-Test setelah memenuhi uji normalitas dan homogenitas. Hasil penelitian menunjukkan bahwa multimedia interaktif memberikan pengaruh signifikan terhadap motivasi belajar dengan nilai signifikansi sebesar 0,040 (p<0,05) dan mean difference sebesar 4,098. Selain itu, multimedia interaktif juga berpengaruh signifikan terhadap hasil belajar siswa dengan nilai signifikansi sebesar 0,001 (p<0,05) dan mean difference sebesar 10,490. Hasil penelitian menunjukkan bahwa penggunaan multimedia interaktif mampu meningkatkan keterlibatan siswa selama pembelajaran sehingga berdampak pada meningkatnya motivasi dan hasil belajar. Dengan demikian, multimedia interaktif dapat dijadikan alternatif media pembelajaran yang efektif pada materi sistem pencernaan manusia. Implikasi penelitian ini menunjukkan bahwa multimedia interaktif dapat dimanfaatkan oleh guru sebagai alternatif media pembelajaran untuk menciptakan proses pembelajaran yang lebih menarik, meningkatkan keterlibatan siswa, serta mendukung peningkatan motivasi dan hasil belajar, khususnya pada materi biologi yang bersifat abstrak.
