Abstract

Critical land is caused by unsustainable land use and has an impact on decreasing the function of the land ecosystem. An effort to rehabilitate critical land can be carried out through the implementation of four-dimensional agroforestry (4D Agroforestry). The aims of this research were i) to design a 4D Agroforestry design, and ii) to analyze the growth of ginger (Zingiber officinale), pepper (Piper nigrum), cardamom (Amomum cardamomum), and grass jelly (Cyclea barbata) under the shade of mahogany (Swietenia mahagony) . The number of plants used was 67 ginger seeds, 44 pepper seeds, 187 grass jelly seeds, and 65 cardamom seeds, so the total was 363 plant seeds with an observation duration of 4 WAP. Implementation of 4D Agroforestry is an alternative effort to optimize land management by utilizing 4 dimensions, namely i) length dimension by planting mahogany, ii) width dimension by planting grass jelly (C. barbata), iii) height dimension by planting pepper ( P. nigrum), cassava (M. esculenta), ginger (Z. officinale), and cardamom (Amomum cardamomum), as well as iv) time dimensions for short-term production (production from cassava, grass jelly, ginger and cardamom plants ), medium (production from pepper plants), and long (production from mahogany wood) to achieve sustainable production. Cardamom plants produced the best growth in the parameters of height increase (15.28 cm) and percent survival (98.46%) after 4 WAP. Keywords: agroforestry, farmers, rehabilitation

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

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

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.
