Abstract

The aim of this experiment is to evaluate the impact of chitosan-NPK slow-release fertilizer (CS-NPK SRF) on the germination and growth of silk tree and rice in different planting patterns, as well as to assess the nutrient release rate of the SRF. The germination test followed a complete randomized design, incorporating a single factor (fertilizer type), namely no fertilizer (F0), SRF CS 0.5% weight 0.03 g (F1), SRF CS 0.5% 0.01 g (F2), SRF CS 0.7% 0.03 g (F3), SRF CS 0.7% 0.01 g (F4), and conventional NPK fertilizer (F5). The growth test utilized a 2-factor split-plot design, with the primary factor being the planting pattern (sengon/rice monoculture-SM/RM and sengon-rice agroforestry-AF) and the second factor being the fertilizer type. Results indicate that F2 and F4 yielded the highest germination and growth values in both plants, although not significantly different from F0. These findings suggest that CS-NPK SRF has the potential to enhance plant growth. The AF pattern exhibited lower growth compared to SM/RM, attributed to plant competition. CS-NPK SRF demonstrated a slower nutrient release (47.65% N; 85.01% P; 31.80% K) compared to conventional fertilizers. This slow release could potentially reduce nutrient loss to the environment while enhancing plant nutrient absorption.

Abstract

Land use changes in forest areas for specific purposes (KHDTK)in Mandiangin, South Kalimantan affect the vegetation diversity loss and physical soil properties changes. This study aimed to analyze vegetation characteristics and soil physical properties across different land cover types (rubber/RB, bare land/BL, simple agroforestry/SA, complex agroforestry/CA, and natural forest/NF) on various slope positions (above, middle, and bottom). The method used was purposive sampling for vegetation analysis in 5 land cover types and 3 slope positions with three replications (45 plots). Parameters observed for soil physical properties were Bulk Density (BD), Particle Density (PD) and Porosity The total number of individuals in NF, SA, CA, RB, and BL in order is (1,713,333, 1,035,000, 768,333, 444,167, 375,000 individuals/ha individuals). The dominant species in natural forests are alaban and bangkal gunung, complex agroforestry namely rambutan, durian, nangka, avocado, matoa and mahoni, simple agroforestry namely jengkol, kemiri and mahoni, rubber plantations namely karet, bare land namely karamunting. The highest bulk density was found in natural forest and rubber (1.21 g/cm³). The highest porosity was found in bare land (53.34%) and the lowest in rubber (44.57%). These findings indicate that variations in land cover and slope significantly affect soil physical properties, which is important for sustainable land management.

Abstract

Mitigation actions to address climate change are essential to prevent future adverse impacts, with woody species in forests playing a pivotal role in carbon storage, as exemplified by the agroforestry systems commonly practiced in community forests of Bogor Regency, which integrate woody species and crops. This study aimed to analyze changes in vegetation density using the Normalized Difference Vegetation Index (NDVI) approach, analyze stand structure and composition, and estimate above-ground carbon stocks in the agroforestry land of community forest in Tenjolaya Sub-District, Bogor Regency. The methods used were spatial analysis with NDVI, vegetation analysis, and carbon stock estimation using allometric and destructive methods. The plot size was 50 m × 50 m, totaling 21 plots. NDVI analysis resulted in low density (0.59–0.67), moderate density (0.67–0.78), and high density (0.78–0.85). This study found 178 plant species across 40 families, with Fabaceae and Myrtaceae being the most dominant. The carbon stock is 27.69 tons carbon/ha. Carbon stock is significantly influenced by tree density, number of species, and basal area values. A well-managed community forest has high ecological, economic, and social potential through the development of agroforestry, which can maintain biodiversity and environmental sustainability while storing carbon stocks. Keywords: above-ground carbon, agroforestry, community forest, normalized difference vegetation index, vegetation density

Abstract

ABSTRACT Sawah Luhur Village, Banten community has a fishery cultivation livelihood using silvofishery system. Silvofishery systems have high potential in storing carbon stocks in climate change mitigation. However, baseline data related to blue carbon reservoirs and sources of community income from the silvofishery system are still limited. This research aims to estimate carbon stocks (blue carbon reservoir) and calculate community income in the silvofishery system in Sawah Luhur Village, Banten. The method used was an allometric approach to estimate the amount of potential carbon stocks, analysis of vegetation on 100 plots, and interviews with the community. Biomass and carbon stock data were collected using non-destructive sampling on 20 transects perpendicular to the shoreline with 5 square plots measuring 10 m x 10 m for each transect line. The silvofishery economic assessment in Sawah Luhur Village uses the total economic value approach which is calculated from the sum of the direct benefits of the presence of mangrove resources. It is estimated that the average carbon stock stored in 10 ponds at the stake and pole level yields 94.67 tons/ha. The silvofishery system in fish farming ponds is dominated by milkfish with yields from each pond ranging from IDR 1,500,000 to IDR 7,000,000 per harvest (mangrove and fish components).   Keywords: biomass, carbon, mangrove, Rhizophora mucronata   ABSTRAK Masyarakat di Desa Sawah Luhur, Banten memiliki mata pencaharian budidaya perikanan dengan sistem silvofishery.

Abstract

Climate change poses a threat in the form of temperature elevation, which can alter weather patterns and ecological balance, necessitating urgent mitigation strategies, such as emission reduction and enhanced carbon sequestration in the urban forest. This research aimed to analyse vegetation density through the NDVI approach, assess tree stand structure and composition, and approximate aboveground carbon stocks in the urban forest, specifically in Eduforest, Bekasi Regency, Indonesia. The methodology involved vegetation analysis and carbon stock estimation, utilising allometric and destructive estimation for seedling and understory levels. The high-density class in Eduforest had the highest area increase in 2023, from 0.64 ha in 2013 to 1.31 ha in 2023. There are 36 species found in all growth levels and the understory. The dominant species, such as Swietenia mahagony, Acacia mangium, and Falcataria falcata, are fast-growing. The tree-growth level has the highest carbon stock (39.90 tons/Ha) of the other growth levels. Eduforest can be an alternative effort to maintain vegetation diversity and carbon stock in addressing climate change.

Abstract

Gayo coffee has many benefits in terms of the environment, economy, and socio-cultural aspects, especially for the Gayo tribe. Recently, Gayo coffee has been the main commodity for the plant cultivation of the Gayo tribe, including the Mude Nosar as local farmers. One of the ways to cultivate Gayo coffee is through an agroforestry system. However, limited reports on the tree species composition and its management in Gayo coffee-based agroforestry needs to be explored. This study aims i) to identify the tree species composition and structure, as well as 2) to analyze the management of Gayo coffee-based agroforestry system in Mude Nosar Village. The study method used plot establishment for vegetation analysis, and interviewed the Gayo coffee farmers. The results showed that the number of tree species at all growth stages was 26 species. The highest Important Value Index (IVI) at the understory and sapling level in order was rumput kerbau (Paspalum conjugatum) and Gayo coffee (Coffea arabica), while at the seedling, pole, and tree levels were dominated by lamtoro (Leucaena leucocephala). The local farmers often use lamtoro as a shade tree for Gayo coffee in agroforestry system. The species diversity index (H') showed low values at all growth levels, except for understory plants with moderate values. The horizontal structure of the tree stand showed an inverted J curve, meaning that the regeneration rate is normal. The vertical structure of the tree stand belongs to strata C and D. The local farmers have applied good Gayo coffee management practices through an agroforestry system including land and seed preparation, planting, maintenance, and harvesting techniques. Coffee seeds and seedlings are from natural regeneration. Plant maintenance techniques are carried out by weeding, pruning, organic fertilization, and controlling pests and diseases. The harvest coffee season is generally twice a year. The management of Gayo coffee using an agroforestry system impacts the ecological, economic, and social aspects.
