Abstract

This study aims to determine the profile of interest of high school students in grade XII to become prospective biology educators in the Gen-Z era. The method used in this study is a descriptive method. To achieve this goal, a study has been conducted using a descriptive research design with a quantitative approach. The population of this study was taken from two schools, namely SMA Negeri 8 Pekanbaru totaling 454 students consisting of 12 classes and SMA Negeri 15 Pekanbaru totaling 241 students consisting of 7 classes. The number of samples was taken using the Purposive Sampling technique. The instruments used were questionnaires and interview sheets. Data were obtained by distributing questionnaires, as well as interviews, then the data obtained were analyzed descriptively. the results of the study on the profile of interest of high school students in grade XII to become prospective biology educators in the Gen-Z era were obtained from the analysis of each indicator, namely cognition (knowing) was in the interested category with a percentage of 84%, emotion (feeling) was in the less interested category with a percentage of 73%, and conation (will) was in the less interested category with a percentage of 58%. Meanwhile, in students of SMA Negeri 15 Pekanbaru, it was obtained from each indicator, namely cognition (knowing) was in the interested category with a percentage of 85%, emotion (feeling) was in the less interested category with a percentage of 74%, and conation (will) was in the less interested category with a percentage of 65%. The conclusion of this study is that students of SMA Negeri 15 Pekanbaru are 1% more interested in becoming prospective biology educators than students of SMA Negeri 8 Pekanbaru.

Abstract

Telah dilakukan kegiatan pengabdian kepada masyarakat berupa pelatihan pembuatan yoghurt kulit buah naga kepada masyarakat Desa Bukit Lembah, Kecamatan Kerumutan, Kabupaten Pelalawan. Kegiatan ini merupakan aplikasi dari Pengabdian Bina Desa yang bertujuan meningkatkan kegiatan ekonomi masyarakat desa dengan produksi produk Yoghurt buah naga yang khas dan bernilai jual. Kegiatan pengabdian dilakukan dalam tiga tahap yakni; tahap sosialisasi kepada masyarakat, tahap pelatihan dan tahap bimbingan pembuatan yoghurt dari kulit buah naga. Tahap sosialisasi dilakukan dengan bekerja sama dengan pemerintah desa, Tim Penggerak PKK, serta guru – guru sekolah dari Desa Bukit Lembah Suburl. Tahap pelatihan dilakukan dengan metode demonstrasi langsung, bimbingan dan diskusi terbuka berkaitan dengan pembuatan Yoghurt dari kulit buah naga.

Abstract

The Nibung (Oncosperma tigillarium (Jack) Ridl.) is a plant that serves as the floral mascot of Riau and symbolizes the spirit of unity and brotherhood among its people. Genetic diversity research is essential for the conservation of this species, with DNA extraction being a critical initial step. This study compared three types of buffers: CTAB, Alkyl Benzene Sulfonate (ABS) surfactant detergent, and Sodium Laureth Sulfate (SLS) surfactant detergent. The aim of this research was to identify alternative buffers to replace CTAB and simplify the extraction of genomic DNA from Nibung. Parameters measured included the presence of DNA and DNA concentration, using electrophoresis and a nanodrop spectrophotometer. The results showed that clear genomic DNA bands were successfully obtained for 24 Nibung accessions, with only two accessions, Nibung2s and Nibung6s, showing smeared bands when using the SLS surfactant detergent buffer. The genomic DNA concentrations ranged from 526.2 to 3,829.2 ng/µl. These concentrations are suitable for use as DNA templates in further research. Thus, both ABS and SLS surfactant detergent buffers can be considered viable alternatives to CTAB for extracting genomic DNA from Nibung.  Key words: Buffer; DNA bands; DNA extraction; DNA Concentration; Extraction optimization.

Abstract

Penelitian ini bertujuan mengembangkan Booklet materi keanekaragaman hayati berbasis hasil kajian keanekaragaman vegetasi bawah di Hutan Lindung Sentajo sebagai sumber belajar kontekstual bagi peserta didik kelas X SMA. Penelitian dilaksanakan Agustus 2025 dengan metode survei deskriptif kuantitatif menggunakan transek sabuk pada dua stasiun yang mewakili kawasan terbuka dan ternaung. Data yang dikumpulkan meliputi Indeks Nilai Penting (INP), indeks keanekaragaman (H’), serta parameter fisika-kimia lingkungan. Hasil penelitian ditemukan 39 jenis tumbuhan bawah yang tergolong ke dalam 27 familia dengan total 938 individu. Indeks keanekaragaman menunjukkan kategori sedang, baik pada kawasan terbuka (H’ = 2,621) maupun ternaung (H’ = 2,980), dengan nilai lebih tinggi pada kawasan ternaung yang didukung pH netral, suhu tanah stabil, intensitas cahaya rendah, dan kandungan bahan organik lebih tinggi. Data tersebut kemudian diintegrasikan ke dalam Booklet melalui tahapan pengembangan R&D sederhana yang meliputi analysis, design, dan development serta divalidasi oleh ahli materi dan media dengan hasil validasi 3,74 yaitu sangat valid. Booklet yang dihasilkan dinyatakan layak sebagai media pembelajaran dan berpotensi mendukung pemahaman konsep keanekaragaman hayati serta menumbuhkan kepedulian terhadap pelestarian Hutan Lindung Sentajo.
