MODELING OF LANDSLIDE SUSCEPTIBILITY IN THE CORE ZONE OF THE LORE LINDU BIOSPHERE RESERVE USING GIS
Full text linkLandslide is a very dangerous natural disaster and often occurs in many hilly or mountainous areas, it often occurs without warning and causes loss of life and property, marked by the displacement of slope-forming material in the form of rocks, soil, or material down the slope. This study aims to model landslide-prone areas in the core zone of the Lore Lindu biosphere reserve in Central Sulawesi Province using the overlay method with a score between 6 parameters. The research parameters included land cover/use, rainfall, elevation, slope, soil type, and lithology. The weighting analysis produces three variables that determine the level of landslide vulnerability: slope, land use, and rainfall. The results showed that the level of vulnerability to landslides in the study area was divided into 4 classes, namely 17.482,15 ha (8,10%) non-prone areas, 98.372,96 ha (45,60%) low vulnerability areas, 98.032,51 ha (45,45%). moderate hazard area, and 1.832,04 ha (0,85%) high hazard area. In high vulnerability zones small or large-scale landslides often occur due to high rainfall and steep to very steep slopes, the rock forms in the form of sediment. Vegetation conditions are generally lacking. The areas included in this class are the villages of Bulili, Lawua, Sedoa, Katu, and Karunia
WORKING TIME, PRODUCTIVITY, AND COSTS OF MANUAL WOOD EXTRACTION IN PRIVATE FORESTS
Full text linkWood extraction using human power is a popular wood extraction technique in private forest harvesting in Indonesia. The method is used for transporting short logs over a short distance in flat or steep areas, which do not have adequate transport roads. The study aimed to analyze time consumption, productivity, and costs of wood extraction using human power in private forests. The study was conducted in a private forest in Probolinggo, East Java. The study was carried out in two cutting blocks. The first cutting block was 50 m from the landing, while the second was 250 m. The data collected included working time, productivity, and costs of wood extraction using human power. Working time data were obtained through video analysis, diameter, and tree height data were collected through direct measurements in the field, and cost data was obtained through direct measurements and interviews. Work time analysis was carried out for 73 cycles for cutting block 1 and 57 cycles for cutting block 2. The results showed that the workers spent most of their time on loaded trips, followed by empty travel, and for personal purposes. The lowest working time was placing and arranging the wood at the landing. The average wood extraction time per cycle was 4.49 minutes for a skidding distance of 50 m and 16.30 minutes for a skidding distance of 250 m. The results showed that the productivity of wood extraction using human power varied from 0.45 to 1.75 m3/hour. The cost of wood extraction using human power in private forests was IDR. 13.33/m3 for a skid distance of 50 m and IDR 51.85/m3 for a skidding distance of 250

LEAF ARCHITECTURE OF THE AVERRHOA COLLECTION AT BOGOR BOTANICAL GARDEN
Full text linkThe Bogor Botanical Garden (KRB) is a significant conservation site in Indonesia, serving as a sanctuary for a diverse range of plant species, including the genus Averrhoa, which holds both economic and ecological value. Plant morphology studies are essential for species classification and biodiversity conservation. This study aims to identify the morphological characteristics of leaves from three Averrhoa species (Averrhoa bilimbi, Averrhoa carambola, and Averrhoa dolichocarpa) as a tool for field identification. Conducted at the Morphology, Anatomy, and Cytology Laboratory of the Bogor Botanical Garden, the research utilized visual observation and digital microscopy to analyze key leaf traits. Principal Component Analysis (PCA) and cluster analysis revealed significant differences in adaxial leaf color and lamina shape, although certain characteristics, such as abaxial color and leaf margin type, were similar across species. These findings demonstrate that leaf architecture is an effective means of identifying Averrhoa species and contribute to taxonomy and biodiversity conservation efforts. Further research is recommended to expand sampling and explore genetic correlations

Full text linkThe 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
CORRELATION OF KNOWLEDGE AND COMMUNITY PARTICIPATION IN LAND CONSERVATION-BASED AGROFORESTRY: A CASE STUDY IN TANJUNG AGUNG VILLAGE, LAMPUNG
Full text linkThe conversion of forest land to agriculture has affected the ecosystem in the upstream area of Way Betung Watershed, including Tanjung Agung Village. This study aims to analyze the relationship between knowledge, community participation, and agroforestry land conservation. The study was conducted on 30 respondents using a structured questionnaire, the results of which were analyzed using the Spearman Rank correlation test. The results showed that the level of community knowledge was in the moderate category (mean score 2.3), while the level of participation was high (mean score 3.7). The level of agroforestry land conservation was recorded in the moderate to high category (mean score 3.3). Correlation analysis showed a significant relationship between knowledge and community participation (ρ = 0.414, p = 0.023) with sufficient closeness, but no significant relationship was found between knowledge and land conservation (ρ = 0.219, p = 0.245) or participation and land conservation (ρ = 0.291, p = 0.119). This study highlights that increasing community participation has great potential to support the success of agroforestry conservation, although the contribution of knowledge needs to be strengthened. The novelty of this research lies in the in-depth analysis of the level of relationship between social variables in supporting agroforestry-based conservation in the strategic upstream area of the Way Betung Watershed
