Abstract

City development plays a very important role in the city environment itself because of the large influence it can have, one of which is the loss of the natural environment resulting in its function in the ecosystem also continuing to be lost. The purpose of this research is to analyze the types of protective trees and their health in the green belt in Kotamobagu City. The method used in this research is the survey method. There are 2 general data collection stages in this research, namely primary data and secondary data and using a percentage formula as a benchmark to see the health level of protective trees in Kotamobagu City. This requires intensive activities to minimize damage to the protective trees. As a result of the research, it was found that intensive activities were needed, including the maintenance and management of protective trees on the green lane of the road. Maintenance of protective trees includes pruning, felling (for trees that are old and have the potential to fall), wound care, staking, controlling pests, diseases and invasive plants and replanting. The management includes making boards prohibiting the sticking of advertising banners on protective trees, prohibiting burning and dumping rubbish near trees, recording planting times, using tree seeds that are suitable for urban areas, conducting outreach to the community and monitoring regularly to prevent accidents or material loss due to fallen trees.

Abstract

Ethnoecology is a science that studies the relationship between humans and the environment. This relationship is related to the use of natural resources around them to continue life using local wisdom, namely the agroforestry system. Ecologically, economically, and socially, the agroforestry system planting patterns can help reduce soil fertility degradation due to human activities that exceed the carrying capacity of the land. The aim of the research was to determine land management and manifestations of land management for durian plants that implement the agroforestry system. The research used qualitative methods with techniques namely collecting data, analyzing data, and drawing conclusions. Data collection used snowball sampling techniques with an unlimited number of respondents. The results explain that (1) land management, tillage, fertilization, crop rotation, and fallow periods on durian plantations have not been managed optimally, resulting in the production of durian plants not being optimal; (2) the manifestation of land management is divided into two, namely traditional and semi-traditional agroforestry systems and these two systems have differences in land management, namely organic and non-organic. Keywords: agroforestry systems, durian, ethnoecology, land management

Abstract

The purpose of this study was to determine the distribution of natural growth at each growth level of matoa (Pometia pinnata) based on altitude in the forest group of Badaro Village, Modayag District, East Bolaang Mongondow Regency. The method used in this study is the survey method, while data collection uses the plot sampling method technique in the research area. The results of the study showed that in the Badaro Village Forest Group, natural stands of Pometia pinnata were spread from an altitude of 300 - 700 m above sea level. The largest number was in the sapling phase with 15 individuals, while the smallest number was in the tree phase with 6 individuals. The number of Pometia pinnata individuals in the seedling phase was 2 individuals at an altitude of 300 m above sea level, 3 individuals at an altitude of 400 m above sea level, 2 individuals at an altitude of 500 m above sea level, 2 individuals at an altitude of 600 m above sea level, and 1 individual at an altitude of 700 m above sea level. The number of Pometia pinnata individuals in the sapling phase was 1 individual at an altitude of 300 m above sea level, 4 individuals at an altitude of 400 m above sea level, 4 individuals at an altitude of 500 m above sea level, 2 individuals at an altitude of 600 m above sea level, and 4 individuals at an altitude of 700 m above sea level. The number of Pometia pinnata individuals in the pole phase was 2 individuals at an altitude of 300 m above sea level, 1 individual at an altitude of 400 m above sea level, 1 individual at an altitude of 500 m above sea level, 1 individual at an altitude of 600 m above sea level, and 2 individuals at an altitude of 700 m above sea level. Meanwhile, the number of Pometia pinnata individuals in the tree phase is 1 individual at an altitude of 300 meters above sea level, 2 individuals at an altitude of 400 meters above sea level, 1 individual at an altitude of 500 meters above sea level, 1 individual at an altitude of 600 meters above sea level, and 1 individual at an altitude of 700 meters above sea level. The distribution of natural growth of matoa (Pometia pinnata) at each growth phase based on altitude is the same or even at each altitude, but the higher the location, the fewer individuals are found.

Abstract

Bogani Nani Wartabone National Park (BNWNP) is the largest land national park area in Sulawesi. There are so many potential medicinal plants found in this area, but data regarding medicinal plants is still very minimal. Therefore, it is very necessary to carry out identification activities related to medicinal plants in the BNWNP area. This research aims to find out what types of medicinal plants exist, how they are known and used by the community, and how medicinal plants are distributed in the research location. This research was carried out at the Toraut location in the BNWNP area. This research is exploratory research where primary data was taken by direct survey and secondary data was obtained through interviews and literature study. The research results showed that there were 13 types of plants from 11 families. The parts of plants that have medicinal properties that have been used by local communities in the toraut location for generations include bark, stems, leaves, flowers, fruit, roots and sap. The most used part is the bark. Medicinal plants scattered in the Toraut BNWNP location are then clustered into 4 quadrants with the largest/dominant distribution in quadrants 2 and 3, namely in the north and east.
