Abstract

Introduction: The Meliaceae family is a group of flowering plants that are widely distributed in tropical and subtropical regions around the world. Some of its members have important economic value. Based on initial surveys in the Bogani Nani Wartabone National Park area, especially the Hungayono tourist attraction area of Gorontalo Province, it is known that there are various species of Meliaceae familli plants. However, it has not been identified what types of Meliaceae plants are and how the value of diversity index in the tourist attraction area. Methods: The purpose of this study was to determine how the diversity of Meliaceae plant species in the Hungayono tourist attraction area of Gorontalo Province. Data collection techniques using exploratory or cruising methods using sampling techniques Probability Sample. Findings: The results of the study found 10 species of Meliaceae familli plants in the Hungayono tourist attraction area. The index value of plant diversity of Meliaceae familli found in the Hungayono tourist attraction area is 1.91 with moderate criteria which indicates a fairly stable ecosystem condition. Conclusion: these findings provide valuable baseline data on the Meliaceae family in the region, contributing to future conservation and biodiversity management efforts in the area. Novelty/Originality of this article: The novelty of this research lies in the first recorded identification and diversity assessment of Meliaceae species in the Hungayono tourist attraction area.

Abstract

The development of Limboto Lake  Site as the pilot area of Gorontalo Geopark is one step  in rescuing the lake. This research aims to analyzed  the vegetation structure, estimate biomass, and assess the carbon stock value of the vegetatio at the Limboto Lake site. This study employed a purposive sampling method. Important Value Index, a measure used to evaluate plant vegetation structure, was calculated based on Realtive Density, Relative Dominance, and Relative Frequency values. Biomass estimation and carbon stock assessment were conducted using allometric equations. The study’s finding showed that the vegetation surrounding Soekarno's landing area exhibited the highest IVI (sawlogs) scores for Swietenia mahagoni tree at 82.86%, Leucaena leucocephala saplings at 79.56%, and Manihot esculenta seedlings at 46.33%. Leucaena leucocephala consistently achieved the highest IVI score within the Limboto Lake area with a score as high as 76.90%, followed by Leucaena leucocephala on the sapling level with a score as high as 70.03%, and Nauclea orientalis on the seedling level with a score as high as 53.06%. Swietenia mahagoni, Samanea saman, and Leucaena leucocephala are three species with stems that predominate at the sawlog level and sapling, and these stems have high carbon absorption values.
