Abstract

A research to study biomass classification by using GIS has been conducted at forest area in Ambon, Province of Maluku. The aims of this research were to find out composition of forest vegetation with its distribution, to determine biomass potency distribution of vegetation and to make classification of biomass potency, air temperature and light intensity distribution. This research used survey method. The vegetation biomass was measured by using allometric and weighted scoring method. By using GIS, definite score can be formatted. The result showed that composition of forest vegetation could be determined, and its biomass potency could be measured and presented on digital map. The digital map of biomass potency, air temperatures and light intensity distribution can be arranged successfully with 3 classifications: low 0.15 ha (17%), moderate 0.31 ha (37%) and high 0.39 ha (46%).   Keywords: biomass classification, LULUCF, CDM, GIS, allometric equation

Abstract

This study aims to determine the structure and composition of plant species in Dusung land management in Luhu Village, discover the combination of plant species at various altitudes, and compare MPTS (Multi-Purpose Tree Species) plants and woods in the Dusung pattern. The sampling used the Stratified Sampling method, i.e., selecting locations based on altitude according to the research objectives and vegetation analysis carried out by the plot line method. For each altitude, 15 plots were made for each growth stage for vegetation sampling by recording the species, number, diameter at breast height (dbh) for the stage of poles and trees. The combination of the Dusung pattern plant species in Luhu Village is distinguishable at each altitude. Cloves are dominant at an altitude of >300-500 masl and >500 masl. The Sago tree stage is dominant at an altitude of 0-300 masl, while the dominant pole stage is Cocoa at 0-300 masl. The higher the site, the smaller the combination of plant species found in the Dusung Pattern in Luhu Village. The community prefers the combination of MPTS plants over wood species on Dusung in Luhu Village. The combination of plants in the Dusung Pattern research plot did not find short-lived plants (annual). It only found long-lived plants, i.e., trees (perennial) with a vegetation structure similar to a forest; therefore, it is more suitable to be called "Forest Garden".

Abstract

Manual measurements to estimate the height and diameter of sago stems can be performed directly. However, estimates of height and diameter from land cover using remote sensing or aerial photographic coverage have not been widely featured in articles at home or abroad. To determine the potential and distribution of sago plant species that can be produced per area in the sago forest area, we mapped the sago land area using drone aircraft to cover the sago land area. We determined the diameter and height classes of sago plants using a Digital Surface Model (DSM) data application method. The results of the analysis showed that there was a distribution of diameter and height of sago plants varying according to height, namely for strata-level seedlings (0 to 6 m) as much as 100, saplings (6 to 12 m) as much as 818, poles (12 to 18 m) as much as 3,332, and trees (> 18 m) as much as 3.79. for the area of sago land mapped, and can be processed into an orthomosaic covering an area of 126,883 ha.

Abstract

Agroforestry, commonly referred to as wanatani in Indonesia, can be simply defined as the practice of planting various types of trees on agricultural land, typically carried out by farmers. Agroforestry studies are not only analyzed from technical and biophysical aspects but also from socio-cultural and economic perspectives. This study examines the traditional agroforestry system, particularly the dusung farming pattern that combines forestry and agricultural crops in Negeri Hatu, Central Maluku Regency. The purpose of this research is to determine the income of farmers practicing the dusung agroforestry pattern and to identify the factors influencing their earnings. Data collection in the field was conducted using purposive sampling. The characteristics of respondents managing dusung agroforestry systems were determined based on age, education level, land area, number of land units, and land ownership status, ensuring they represented the target farmer population for the study. The results of the study showed that the income of agroforestry farmers in the hamlet in Negeri Hatu was Rp 353,955,000,-, but the per capita income per month was only Rp. 14,211 below the Provincial Minimum Wage. Three factors that affect the income of agroforestry farmers in the hamlet in Negeri Hatu are land area, production costs, and market prices.

Abstract

The pitih wood plant (Melaleuca leucadendra) is a type of plant that belongs to the guava tribe (Myrtaceae) which can produce one of the essential oil products in Indonesia. Eucalyptus plants can be cultivated by generative (seed) and vegetative propagation methods (shoot cuttings with rejuvination techniques, branch cuttings, shoot cuttings, root cuttings, grafts).  However, related to the root structure of the rhizome and the value of the biomass content of this plant, it has not been widely published. This is the impetus to conduct research related to the root structure of the rhizome and the biomass content and stored carbon content of the eucalyptus plant section by direct measurement methods in the field and analysis in the laboratory. From the plot of eucalyptus plants, it can be seen that the selected sample has sturdy rhizome roots with similar plant height characteristics, both for the growth rate of the mother plant and the saplings of the mother plant which generally have an even height and are not too.

Abstract

Agroforestry management plays a crucial role in ensuring the sustainability of the dusung system by supporting both the local economy and environmental conservation. This study aims to examine the management of nutmeg-based agroforestry and to analyze the economic value of the dusung agroforestry farming system as a source of household income for farmers. A descriptive-exploratory method with a non-experimental approach was used, employing data collection techniques such as observation, interviews, questionnaires, literature review, and documentation. The data were analyzed descriptively through tabulation and interpretation, in line with the objectives of the study. The results show that dusung management is carried out hereditarily by farming families using a mixed cropping system that combines nutmeg with other crops on the same plot of land. Maintenance, harvesting, and post-harvest processing activities are conducted independently and still rely on local knowledge. This management model reflects a form of traditional agroforestry that is adaptive to the social and ecological conditions of the community.
