Abstract

There are 69 species of Mangifera distributed worldwide, and approximately 35-40 of these species are found in tropical Asia. This widespread distribution naturally affects the functional characteristics of Mangifera species. This research aims to determine the variation in leaf functional traits of Mangifera species based on their subgenus (Mangifera and Limus) and the differences in elevation locations (Bogor Botanical Garden/lowland and Cibodas Botanical Garden/highland). The leaf's functional traits were measured through ten parameters: Fresh Weight (FW), Dry Weight (DW), Leaf Area (LA), Specific Leaf Weight (SLW), Specific Leaf Area (SLA), Leaf Dry Matter Content (LDMC), Chlorophyll Content (CC), Stomata Density (SD), Stomata Length (SL), and Stomata Width (SW). The observational data were analyzed using Pearson Correlation, One-Way ANOVA, and Post Hoc Test with Duncan’s Multiple Range Test (DMRT). The results showed differences in Mangifera species' leaf functional traits between subgenus and locations. It was observed that DW, LA, SLA, and CC were higher in the subgenus Mangifera than in the subgenus Limus. The results also show that the SLW, SLA, LDMC, and CC values are influenced by altitude. The differences in the functional traits of Mangifera species are driven by environmental factors that induce phenotypic changes through plasticity, reflecting their adaptation to different environments.

Abstract

Penelitian ini bertujuan untuk menghitung jumlah mikroalga di Sungai Kampai dan diiaplikasikan kedalam suplemen penuntun praktikum Mikrobiologi materi perhitungan mikroorganisme. Metode penelitian yang digunakan adalah metode Penelitian dan Pengembangan (Research and Development). Hasil perhitungan jumlah mikroalga yang ditemukan di Sungai Kampai yaitu stasiun hulu sebanyak 124 ind/ml stasiun tengah 140 ind/ml dan stasiun hilir sebanyak 220 ind/ml. Spesies mikroalga yang ditemukan sebanyak 34 spesies, terdiri dari 5 divisi yaitu Crysophyta (14 genus), Cyanophyta (5 genus), Chlorophyta (12 genus) dan Euglenophyta (3 genus). Hasil penyusunan suplemen penuntun praktikum yaitu cover, kata pengantar, daftar isi, pendahuluan, topik, glosarium, dan daftar pustaka. Hasil rata-rata uji validasi ahli yaitu 91,4% dengan kategori sangat valid dan uji keterbacaan terhadap mahasiswa Pendidikan Biologi UNIB dengan persentase 90,13% berkatagori sangat layak untuk bahan ajar mata kuliah Mikrobiologi materi perhitungan mikroorganisme.
