Abstract

Orangutan Sumatera merupakan salah satu kera besar yang hanya ditemukan di Indonesia. Menurut data IUCN (International Union for Conservation of Nature), keberadaan Orangutan Sumatera (Pongo abelii L.) saat ini termasuk satwa dengan status kritis yang merupakan status kepunahan tertinggi. Kepunahan Orangutan Sumatera ini salah satunya disebabkan konflik dengan manusia akibat rendahnya tingkat pemahaman sehingga memunculkan suatu keterbatasan ilmu pengetahuan tentang pentingnya keberadaan Orangutan. Konflik ini dapat di hindari dengan mengetahui sikap masyarakat sekitar habitat Orangutan sesuai dengan tujuan penelitian ini yaitu mengetahui sikap masyarakat Gampong Jalin, kota Jantho Kabupaten Aceh Besar terhadap keberadaan pusat reintroduksi Orangutan Sumatera di Jantho. Instrumen yang digunakan dalam penelitian ini adalah tes dan angket sikap. Data sikap masyarakat dianalisis dengan rumus penskoran data sikap. Hasil penelitian diperoleh bahwa nilai rata-rata sikap masyarakat Gampong Jalin terhadap keberadaan pusat reintroduksi Orangutan Sumatera (Pongo abelii L.) yaitu 65 dengan kategori netral.

Abstract

Learning media based on qur'anic values significantly contribute to student outcomes. One reason for low learning outcomes in classes is that teaching materials rooted in Islamic values connect students with moral principles and shape their character, thereby strengthening the integration of science and religion. This research aims to improve student learning outcomes through e-magazine learning media based on qur'anic values. The research design is a quantitative experimental study with a pre-experimental method, specifically the One Group Pretest-Posttest Design. The sample consists of one class, X-3, totaling 30 students, selected using purposive sampling. The instrument used is a test consisting of 20 multiple-choice questions. Data were analyzed using the N-gain formula. The results showed an increase in student learning outcomes, with an average pretest score of 30.19. After instruction with e-magazine learning media based on qur'anic values, the posttest average improved to 80.19. The N-gain value was 0.72, indicating a high level of improvement. It can be concluded that the application of e-magazine learning media based on qur'anic values in biodiversity material significantly enhances student learning outcomes

Abstract

Symphalangus syndactylus is a long-armed primate that plays a crucial ecological role as a pollinator and seed disperser. However, this species is currently classified as endangered. According to the IUCN (International Union for Conservation of Nature) in 2021, Siamang populations have been declining due to extensive deforestation, which has reduced the availability of their natural food sources.This study aimed to identify the diversity of plant species consumed by Siamangs. We conducted an exploratory survey using the line transect method across three trails. Data on food plants were collected along 1000-meter transects in each trail. Plant diversity was analyzed using the Shannon-Wiener diversity index (H' = -∑ Pi ln Pi).The results revealed 56 species of food plants from 22 families. The overall diversity index value of H'=2.74 indicates that the diversity of Siamang food plants at Soraya Research Station is at a moderate level.

Abstract

Sungai Krueng Lamnyong merupakan kawasan perairan yang berpotensi mengandung bakteri kitinolitik karena menjadi habitat bagi organisme bercangkang seperti udang, kepiting, tiram, dan kerang. Kitin merupakan biopolimer alami yang umum ditemukan di lingkungan perairan dan dapat terdegradasi oleh enzim kitinase yang dihasilkan oleh mikroorganisme, seperti bakteri kitinolitik. Enzim kitinase berperan dalam proses daur ulang kitin, sehingga mencegah terjadinya akumulasi limbah cangkang organisme perairan. Penelitian ini bertujuan untuk mengkarakterisasi morfologi bakteri kitinolitik yang diisolasi dari perairan Sungai Krueng Lamnyong, Banda Aceh. Sampel diambil dari tiga lokasi berbeda, yaitu Jembatan Lamnyong, Jembatan Krueng Cut, dan Muara Alue Naga. Dari setiap lokasi diambil tiga sampel, masing-masing dari sisi kiri, kanan, dan tengah sungai. Isolasi menggunakan media agar kitin Congo red berbahan dasar limbah cangkang udang. Pengamatan morfologi bakteri dilakukan secara makroskopis dan mikroskopis. Hasil penelitian menunjukkan keberagaman morfologi koloni: 3 koloni berbentuk circular dan 6 irregular; warna koloni terdiri atas putih (5), putih susu (2), kuning (1), dan merah muda (1). Tepian koloni bergelombang (5), bergerigi (2), dan rata (2). Hasil pewarnaan Gram menunjukkan 2 isolat Gram positif dan 7 Gram negatif, dengan bentuk sel berupa 3 kokus kecil, 2 kokus, dan 4 basil pendek. Bakteri kitinolitik ini berpotensi dimanfaatkan dalam bioteknologi lingkungan, khususnya bioremediasi limbah kitin.
