Published: March 2024

AbstractThe forest land has great potential to provide food and also contributes to achieving Indonesia’s forest and other land uses (FOLU) Net Sink 2030, as a concrete contribution of the forestry sector to addressing national and global needs, which can be done by promoting smart agroforestry. This research aims to provide smart agroforestry model ofsengon(Falcataria moluccana) with arrowroot and cardamom, to analyze thesengongrowth, the arrowroot and cardamom biomass productivities under the agroforestry models. The split-plot design was employed with six cropping pattern as the main plot, in three agroforestry models (sengon-arrowroot;sengon-cardamom;sengon-arrowroot-cardamom) and three monoculture plots, and three levels of the dosage of manure as subplots (0; 250; 500 g). The results showed that higher growth ofsengonwas found in the three agroforestry models (3.0-3.5 m3.ha−1) compared to monoculture (2.1 m3.ha−1). The highest dry weight of leaf, stem, root, tuber, fruit bunch and total biomass of arrowroot and cardamom was produced in the monoculture. These agroforestry models have the potential to support food security and Indonesia’s FOLU Net Sink 2030, which will be prospective mainstreaming in implementing Social Forestry programs.

Abstract
Agroforestry is an agricultural system that integrates primary trees and alternative crops on the same land to provide economic, social, and ecological benefits. One of the agroforestry planting patterns is called Persilan. The purpose of this paper is to investigate the concept of persilan carried out by pesanggem (forest farmers) in several blood types in Java. Researchers observed agroforestry activities in three districts in Java, namely Rembang, Blora, and Tuban. To see agricultural patterns in several regions of Java, we used secondary data studies and Google Maps. In addition, we also collect data through stakeholder surveys to find out the philosophy, land plot, calendar, and ecological function of persilan patterns. The results showed interesting facts related to land parcels in the context of agroforestry which were widely developed in several regions, including Pati, Grobogan, Rembang, Blora, Tuban, to Bojonogoro. Persilan is a form of agriculture where people use Perum Perhutani production forests as their planting land. They plant in the empty parts between the trees by combining primary plants with interstitial plants for 5 years. The concept of Persilan plays a role in maintaining the ecological balance of forests, economic prosperity, and social welfare of local communities.

Abstract
This study investigates the viability of coffee agroforestry systems in supporting Indonesia’s Social Forestry Program and contributing to climate change mitigation efforts. Conducted in the KUPS Kopi Data Baringin management area of West Sumatra, this research assesses the potential of coffee cultivation within an agroforestry system in Baringin Village, Agam District. Data collection encompassed a comprehensive census for social and economic aspects and purposive sampling for vegetation analysis. Findings revealed a diverse range of 29 tree species from 16 families, alongside eight types of agricultural crops from five families. Tree species exhibited lower diversity and abundance indices, while herbaceous and shrub categories demonstrated moderate diversity. Notably, Coffea canephora, the coffee species, exhibited a carbon content of 3.49 tons per hectare, contributing to climate change mitigation efforts and functioning as a valuable CO2 equivalent sink estimated at approximately 13 tons per hectare. Furthermore, the adoption of coffee agroforestry systems resulted in a notable increase in monthly income for KUPS members. These findings underscore the potential of coffee agroforestry systems as a sustainable land-use practice, supporting the Social Forestry Program objectives and making substantial contributions to climate change mitigation in Indonesia’s forest and land management strategies.

Abstract
Peat swamp forest (PSF) provides vital environmental benefits, including carbon storage. However, almost half of the Indonesia’s PSF areas are extensively degraded. Internal threats such as drainage contribute to peat drying, vegetation damage and heightened fire risk. Equally, forest edges are threatened from human activity and fire spread, leading to forest edge regression. This study assesses biophysical changes within an area of intact tropical PSF and along their edges in Central Kalimantan. To assess these threats, we established seven transects perpendicular to the forest edge, transitioning from degraded to intact forest. Forty-nine dipwells, and three loggers were installed to assess drainage and subsidence. We established seed traps and seedling plots along three transects at three distances from the forest edge (three replicates per distance) to assess forest edge regeneration potential. Furthermore, we are analysing historic remote sensing data from the last two decades to study land cover change and forest edge loss related to fire. Equipment was established February 2022, with data collection underway for 12 months. Here, we present our initial findings. The results will provide quantitative and qualitative data analysis to describe potential threat levels facing this forest and give recommendations for developing a targeted conservation action plan.

Abstract

Saurauia pendula Blume is a species of genus Saurauia and belong to Actinidiaceae family. Saurauia pendula spread over on several highlands or mountains in Java Island. Mount Slamet is the second highest mountain on Java with naturally good vegetations. The existence of several threats such as forest fires, destruction, deforestation and forest degradation has caused the condition of these plant species to begin to require attention. This study aims to determine the population of S. pendula, its potential regeneration and spatial distribution model in Mount Slamet area. The study was conducted on four (north, south, west and east) slopes in 2019-2020. Research on population conditions was carried out by following hiking trails and making new paths around the center of suitable habitat. Coordinate data is taken to make spatial analysis using Maximum Entropy (MaxEnt). The results showed that the number of S. pendula was found on the north, west and south slopes at an altitude of 1010-2024 masl. This species has a significant association with Saurauia microphylla de Vriese., Glochidion obscurum (Roxb. ex Willd.) Blume and Castanopsis argentea. The number of mature plants is 106 individuals, which have important role in the distribution of this plant. Analysis of the spatial distribution model shows that S. pendula is estimated to be widely distributed on the western slopes of Mount Slamet.

Published: March 2024

Abstract
Kalimantan possesses diverse local fruit potentials, including the genus Artocarpus (local name: Tarap). There are approximately 13 Artocarpus species in Kalimantan, two of which are endemic to the region: Artocarpus nitidus Trecul ssp. borneensis (Merr.) Jarrett and Artocarpus odoratissimus Blanco. A. odoratissimus, commonly known as Binturung in South Kalimantan, is a less frequently encountered local fruit than other Tarap species. The destruction of natural habitats, mainly due to land use conversion from natural forests to other purposes, has led to a decline in Binturung populations in the wild. This study comprehensively reviews relevant literature on A. odoratissimus, encompassing fruit characteristics, potential benefits, and conservation status. Expert interviews, including botanists and biodiversity specialists, are conducted to gather additional information on the commercial potential and conservation challenges associated with Binturung fruit in Kalimantan. This research provides a comprehensive overview of the potential and challenges in utilizing A. odoratissimus fruit in Kalimantan. The findings are expected to serve as a foundation for sustainable conservation strategies and commercial utilization, promoting the conservation of natural resources and enhancing the well-being of local communities.

Abstract
Forest fragmentation has emerged as an important driver of habitat loss and biodiversity degradation, but research on this topic has been limited, particularly in island areas. The aim of this study is to address this research gap by investigating forest fragmentation in the islands of Bali, Nusa Tenggara and Maluku. To identify the potential for forest fragmentation in these regions, Simmon’s Index was used. Land cover maps derived from the Sentinel-2 dataset for the period 2017-2022 were obtained from Google Earth Engine. They were combined with forest area maps to generate the fragmentation index. Our results show that Maluku has the highest fragmentation index with an average of 0.32. This is followed by East Nusa Tenggara with 0.31, North Maluku with 0.21, West Nusa Tenggara with 0.13 and Bali with 0.04. During the period 2017-2022, the average number of developed land, expressed in polygons, was 2533 in Maluku, and 3706, 1412, 1878, and 637 in East Nusa Tenggara, North Maluku, West Nusa Tenggara, and Bali, respectively. The development of a methodology to quantify the potential extent and drivers of forest fragmentation is essential to inform policy makers and guide strategies to protect forest areas and prevent further habitat loss.

Published: March 2024

Abstract
Plant diseases attack all parts of the plant, such as leaves, stems, and roots. The cause of pest attacks is due to several factors, namely environmental conditions that support pathogens, selected plant conditions that are susceptible to disease, and poor maintenance. Disease attacks on the roots include attacks that are harmful to plants, so it is necessary to have effective control carried out by considering the ecology and economy. One of the techniques for controlling plant-disturbing organisms (OPT) can be carried out by utilizing endophytic microbes. This study aimed to explore the types of endophytic bacteria found in balsa and mindi, which have the potential as biological control agents, as well as the effect of using endophytic bacteria in suppressing the growth of root diseases in vitro. The study found that as many as 20 endophytic bacteria were purified from balsa, and 25 individuals were purified from mindi. The hemolysis test and plant hypersensitivity test results showed seven pure isolates with endophytic potential, namely three isolates from balsa and four from mindi.

Abstract
Ameliorant based on local resources is an alternative solution to farmers in sustainably optimise agricultural waste. This study aimed to determine the residual ameliorant formulation from a local resource on the chemical properties of Inceptisols and the production of green beans (Phaseolus vulgaris L.) in central horticultural production of Banuhampu Agam, West Sumatra. This study used a Randomized Complete Block Design (RCBD) with eight treatments and three replications, namely: [A]=Control; [B]=Bamboo biochar (BB)+Tithonia Green Fertilizer (TGF)+Chicken Manure (CM)+Agam Compost (CA); [C]=BB+TGF+CM; [D]=BB+TGF+CA; [E] = BB+CM+CA; [F]=TGF+CM+CA; [G]=Farmer’s tradition (FT) and [H]=Ministry of Agriculture recommendations (MAR). Residual formulation of ameliorant from local resources had a significant effect on chemical properties of Inceptisols (pH, EC, CEC, OC, total N, available P) and total yield (kg plot−1) and % P in green beans, compared to control. Residual ameliorant formulation from local resources (TGF+CM+CA) had improved OC (0.88; 0.72 and 0.56% C) in Inceptisols and total yield (8.30; 5.10 and 4.90 kg plot−1) and 0.002; 0.007 and 0.006% P in green beans, better than the control, FT and MAR. The application of local resource-based amelioration technology is very significant to land optimisation, especially OM.

Abstract
Forests have an important role in the carbon cycle and in the dynamics of storing and releasing carbon in growth, decay, and disturbance processes. Timber harvesting initially reduces the amount of carbon in the forest. This study aims to analyze the magnitude of changes in carbon mass due to timber harvesting. It was conducted in a forest concessionaire located at Siberut of West Sumatra on a natural forest covering about 48,000 hectares. Selective cutting was implemented for logging where the harvestable trees were over 50 cm in diameter. The amount of carbon mass was obtained based on laboratory tests on tree parts, including trunk, branches, twigs, and bark. The average carbon content in each part of the tree is different. The trunk contains 53.86% of carbon mass, the branches are 51.98%, the twigs are 31.58%, the leaves are 27.91%, and the bark is 32.01%. Timber harvesting was conducted at the forest compartment with an average forest stand density of 71.5 trees ha−1 and a felling intensity of 8.8 trees ha−1, causing damage to 16.17 trees ha−1 stands. Timber harvesting causes a decrease in carbon mass reserves of 43.26% from forest carbon mass of 141.89 tons C ha−1 before harvesting to 80.00 tons C ha−1 after harvesting.

Abstract
Forestry and Other Land Uses (FOLU) is one of the critical sectors in low carbon and climate resilience development. Gunung Halimun Salak National Park (GHSNP) can potentially mitigate climate change by increasing carbon stocks. This study aimed to estimate vegetation density using the Normalized Difference Vegetation Index (NDVI), estimate biomass and aboveground carbon stocks, and analyze the relationships of NDVI with vegetation diversity and carbon stocks in the utilization zone of GHSNP. The method used was vegetation analysis and carbon estimation using allometric and destructive testing for seedling and understory levels. The total plots were 15 (a plot size of 50 × 50 m). NDVI was categorized into three classes, specifically class 1 (0,147 - 0,276), class 2 (0,276 - 0,321), and class 3 (0,321 - 0,493). The utilization zone of GHSNP consists of 56 plant species from 40 families. The research location was dominated by Pinus merkusii. The average biomass and carbon concentrations were 131,14 Mg/ha and 61,64 Mg C/ha, respectively. Carbon concentration strongly correlated with the basal area (r = 95,2%). The NDVI value strongly correlated with the number of individual trees per hectare. NDVI can be used as an approach to estimating forest cover.

Published: March 2024

Abstract
Postmining land reclamation and revegetation activities play an important role in restoring vegetation, degraded land and controlling climate change because CO2 is sinking from the atmosphere due to the impact of mining activities. This study aims to estimate the potential for above-ground and below-ground carbon and CO2 absorption capacity at the Binungan Mine Operations Site (BMO), PT Berau Coal, Berau, East Kalimantan. Vegetation analysis was used to estimate the potential carbon stock and CO2 absorption capacity at plant ages 1-10 years using the purposive sampling method of 5 plots (20 x 20 m) each in the post-mining area studied. Biomass and carbon stocks were estimated using existing allometric models. The results showed 14 tree species from 10 families dominated by Fabaceae. Biomass was estimated at 1.13 - 128.31 Mg ha-1, carbon stocks were 0.53-60.3 Mg ha-1, and CO2 absorption was 1.95 - 221.32 Mg ha-1. Reclamation and revegetation in 10 year-old plants on reclamaied land can restore biomass, carbon stock, and CO2 absorption capacity of 70% from the initial baseline.
