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

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

Changes in the landscape and management of natural resources from forest areas to agricultural land are currently an issue, so agroforestry is the right concept to apply to converted land.. The concept of agroforestry offers a solution, whereby the implementation of agroforestry is a land use system that integrates forestry and agricultural crops to create balanced ecological conditions, economic benefits, and local wisdom within the community. The community of Bilalang Baru Village has implemented an agroforestry system with a composition of plants aimed at boosting the community's economy. The purpose of this study is to identify the composition of agroforestry plants in promoting economic improvement in the community. The research method used was descriptive qualitative and quantitative through the exploration of data and facts in the field. Data collection methods included in-depth interviews, observation, and literature study. The results showed that the composition of plant species in agroforestry to promote economic improvement in the Bilalang Baru community was found in agroforestry land consisting of 3 types of timber forestry plants, 8 types of fruit plants, 3 types of industrial plants, 3 types of industrial plants, 2 types of cereal plants, 8 types of vegetable plants, 3 types of tuber plants, and 5 types of rhizome plants.

Abstract

This study aims to analyze the diameter distribution and its relationship to biomass, carbon stock, and carbon sequestration in mahogany trees in the Bonawang urban forest of Kotamobagu. This is a quantitative study that employs the non-destructive sampling method, which allows data collection without permanently damaging the trees, thereby enabling the reuse of the same study subjects. Data collection techniques included both primary and secondary data. Primary data were collected through observations and measurements along a transect, where the starting point of the transect was determined using purposive sampling within a 20-meter-wide area. Secondary data were obtained from journals, books, as well as theories and the results of previous research. The results of the study indicate that the mahogany (Swietenia mahagoni) population consists of 77 individuals with diameter classes ranging from 20 cm to 160.82 cm. The largest number of mahogany individuals was found in the 30 cm to 40 cm diameter class. The total mahogany biomass was 337.98 metric tons, carbon stock was 158.77 metric tons of C, and carbon sequestration was 583.7 metric tons of CO?, with the highest values occurring in the diameter class above 100 cm. The correlations between diameter class (based on the midpoint of the diameter class) and biomass, carbon stock, and carbon sequestration in mahogany trees is very strong, with a positive correlation, and is statistically highly significant. Given that the diameter class > 100 cm (large) accounts for the largest contribution to carbon sequestration, it is recommended that area managers prioritize the protection of these trees from logging activities, as they serve as highly effective carbon sinks in mitigating climate change.
