Abstract

Gunung Halimun Salak National Park (GHSNP) is one of the most biodiversity-rich protected areas in Java, yet it remains highly vulnerable to deforestation and forest degradation. This study examines forest cover dynamics from 1994 to 2024 and projects village-level encroachment risk for 2034. Landsat 5 TM, Landsat 7 ETM+, and Landsat 8–9 OLI imagery were processed in Google Earth Engine to generate the Normalized Difference Fraction Index (NDFI) using spectral mixture analysis of GV, NPV, soil, and shade fractions. Changes in NDFI (ΔNDFI) were used to classify degradation, deforestation, regrowth, and intact forest. Encroachment risk mapping was modeled using a 3 × 3 kernel neighborhood with two analytical approaches: the sum of risk weight and the majority of risks around. Forest cover declined by 19,424 ha between 1994 and 2004, largely driven by illegal encroachment linked to governance uncertainty in 2003. An increase of 6,678 ha during 2004–2014 reflects the impact of restoration initiatives and strengthened area protection, although a subsequent decline of 1,992 ha occurred between 2014 and 2024 due to renewed encroachment. Model evaluation indicates low predictive performance for both kernel methods (Precision 4%). Despite this limitation, areas of elevated risk consistently appeared along forest edges near settlements and footpath access routes. Citorek Kidul was identified as the village most susceptible to encroachment in 2034. Improving the accuracy of encroachment prediction will require the integration of socio-economic drivers and advanced machine-learning approaches capable of capturing the complex and non-linear patterns of forest encroachment.

Abstract

ABSTRACT Leuser Ecosystem Area (LEA) is an essential tropical forest ecosystem with an expansive approximately 2,6 Mha. Baseline data of tree species diversity and structure around LEA is limited, whereas vegetation cover as a portion of forest monitoring in GLNP still needs to be considered. The objectives of this study were 1) to estimate vegetation cover changes in LEA in 2016, 2020, and 2021 and 2) to analyze vegetation composition and structure in the natural forests (NF) of GLNP, as well as in the agroforestry system (AF) of Mude Nosar Village, Central Aceh Province where the parts of LEA. The methods used were the Normalized Different Vegetation Index (NDVI) for vegetation cover estimation and vegetation analysis in both locations. NDVI analysis resulted in 5 classes of vegetation cover in LEA, to be specific non-vegetation (class 1), very low dense vegetation (class 2), low dense vegetation (class 3), moderately dense vegetation (class 4), and highly dense vegetation (class 5). LEA vegetation cover in 2016, 2020, and 2021 is dominated by class 5 (highly dense vegetation). The most frequent seedling, sapling, pole, and tree species that grew in NF of GLNP in order were Geseng tanduk (Quercus sp.), Geseng minyak (Lithocarpus lucidus), Geseng pagar anak (Lithocarpus sp.), and Geseng batu (Lithocarpus conocarpus). The dominant species in AF were rumput kerbau (Paspalum conjugatum) at the understory and seedling level, coffee (Coffea arabica) at the sapling level, lamtoro (Leucaena leucocephala) at the pole and tree level. Tree structures in the NF of GLNP are reverse J-curves, while in AF of Mude Nosar Village are not fully reverse J-curves. The success of AF depends on considering tree species composition and structure, along with the specific needs and goals of the landowners. Consequently, enrichment planting in AF is necessary for biodiversity improvement.   Keywords: agroforestry, Gunung Leuser National Park, Mude Nosar Village, species composition, tree structure         ABSTRAK Kawasan Ekosistem Leuser (KEL) merupakan ekosistem hutan tropis yang penting dengan luas sekitar 2,6 juta hektar. Data dasar mengenai keanekaragaman dan struktur spesies pohon di sekitar KEL masih terbatas, sementara tutupan vegetasi sebagai bagian dari pemantauan hutan di Taman Nasional Gunung Leuser (TNGL) masih perlu diperhatikan. Tujuan penelitian ini adalah 1) memperkirakan perubahan tutupan vegetasi di KEL pada tahun 2016, 2020, dan 2021 serta 2) menganalisis komposisi dan struktur vegetasi di hutan alam (NF) TNGL serta sistem agroforestri (AF) di Desa Mude Nosar, Kabupaten Aceh Tengah, yang merupakan bagian dari KEL. Metode yang digunakan meliputi indeks vegetasi berbasis Normalized Difference Vegetation Index (NDVI) untuk estimasi tutupan vegetasi dan analisis vegetasi di kedua lokasi. Analisis NDVI menghasilkan lima kelas tutupan vegetasi di KEL, yaitu tanpa vegetasi (kelas 1), vegetasi sangat jarang (kelas 2), vegetasi jarang (kelas 3), vegetasi sedang (kelas 4), dan vegetasi sangat rapat (kelas 5). Tutupan vegetasi KEL pada tahun 2016, 2020, dan 2021 didominasi oleh kelas 5 (vegetasi sangat rapat). Spesies yang paling sering ditemukan pada tingkat semai, pancang, tiang, dan pohon di NF TNGL secara berurutan adalah geseng tanduk (Quercus sp.), geseng minyak (Lithocarpus lucidus), geseng pagar anak (Lithocarpus sp.), dan geseng batu (Lithocarpus conocarpus). Spesies dominan di AF adalah rumput kerbau (Paspalum conjugatum) pada tingkat bawah dan semai, kopi (Coffea arabica) pada tingkat pancang, serta lamtoro (Leucaena leucocephala) pada tingkat tiang dan pohon. Struktur pohon di NF TNGL mengikuti pola kurva J-terbalik, sementara di AF Desa Mude Nosar tidak sepenuhnya mengikuti pola J-terbalik. Keberhasilan AF bergantung pada pertimbangan komposisi dan struktur spesies pohon, serta kebutuhan dan tujuan pengelola lahan. Oleh karena itu, penanaman pengayaan dalam sistem AF diperlukan untuk meningkatkan keanekaragaman hayati.   Kata kunci: agroforestri, Desa Mude Nosar, komposisi spesies, struktur pohon, Taman Nasional Gunung Leuser

Abstract

The agroforestry system is a land management approach that considers social, economic, and environmental factors. Gayo coffee (Coffea arabica) is the primary commodity for the residents of Mude Nosar Village in Central Aceh, where the agroforestry technique is applied. However, pest and disease attacks on coffee plants reduce productivity. Pest and disease identification research has yet to be completed. The purpose of this study was to identify the different types of pests and diseases to determine the attack intensity and control potential in the Gayo coffee agroforestry system. Purposive sampling, vegetation analysis, and pest and disease attack calculation were the methods used. The Forest Pathology Laboratory detected symptoms of the attack by examining the fungus’ macroscopic and microscopic structure. The pests discovered included fleas (Heteropsylla cubana) and caterpillars (Hyposidra talaca). The diseases discovered were anthracnose and leaf rust. The intensity of fleas, anthracnose, and leaf rust attacks was less than 30% each. Using coffee skin waste, livestock manure, and natural enemies, may control pests and conditions in the Gayo coffee agroforestry system while also implementing organic agroforestry management. Natural enemies include Trichoderma harzianum, weaver ants (Oecophylla smaragdina), and spiders (Araneae) are suggested. Keywords: agroforestry, Central Aceh, disease, Gayo coffee, pest

Abstract

The Subur farmer group is located in Sugihwaras Village, Maospati District, Magetan Regency, East Java which develops sugarcane (Saccharum officinarum) and teak (Tectona grandis) with a monoculture pattern. Monoculture cultivations produce a single income for farmers, hence other adaptive intolerant commodities and sites that generate alternative income are needed. One of them is Porang (Amorphophallus muelleri Blume). The farmer group’s knowledge and skills related to porang cultivation are very limited. The aims of this activity were: 1) To train farmer groups related to porang cultivation planted with agroforestry patterns; 2) To analyze knowledge changes of farmer groups regarding porang cultivation; and 3) To evaluate the implementation of the training program. The results showed that training on porang cultivation and making agroforestry demonstration plots were able to increase the knowledge of the Subur farmer group. The pre-test score was 65,1 (55%) while the post-test was 88,6 (75%). Based on the evaluation of the assessment of training activities by farmers, as many as 74,3% of farmers stated that they strongly agreed that the porang cultivation training was very useful and suitable for their needs. In addition, the activity feasibility analysis showed that this training is categorized as very feasible to be implemented with a score of 94%. Porang cultivation training for the Subur farmer group was able to increase knowledge and the potential to earn additional income for the people of Sugihwaras Village, Magetan Regency, East Java.

Abstract

Article Highlights- Pohpohan (Pilea melastomoides) is the main commodity cultivated by using traditional agroforestry in the traditional zone of Gunung Halimun Salak National Park as a fresh vegetable.- There is a limited database of plant species diversity in the traditional zones, which is dynamic and needs further research.- This study found 54 tree species from 37 families with the dominant family being Rubiaceae.- Most farmers cultivated Pohpohan by conducting plant spacing, maintenance, and harvesting. Their income is USD 154 – 256/month. AbstractGunung Halimun Salak National Park (GHSNP) is Java's largest tropical mountain forest. GHSNP is still facilitating community grounds around GHSNP with the existence of a traditional zone. Pohpohan (Pilea melastomoides) is the primary commodity in the traditional zone cultivated by the local people around GHSNP. Pohpohan is planted using traditional agroforestry planting patterns. The traditional zone has a limited plant species diversity and management database, so further study is necessary. This study was conducted in the traditional zone of GHSNP, specifically at the agroforestry system in Tamansari Village, Bogor Regency. Data collection of tree diversity was conducted by establishing 25 plots. This study also interviewed 30 local farmers belonging to the Mandiri farmer group. There are 54 species from 37 families. Rubiaceae, Malvaceae, Fabaceae, and Phyllanthaceae families are the most common families. Pinus merkusii, Agathis dammara, and Maesopsis eminii have the highest important value index (IVI) values. Understorey and seedlings have a low category on H' due to the dominant planting of Pohpohan. Most respondents are people aged 35-55 (70%) with a farming area of 1000 m2. They cultivate Pohpohan by conducting plant spacing, plant maintenance (e.g., soil cultivation, weeding, fertilization), and harvesting. Most farmers conduct fertilization 9 times/year. Farmers produce 30.000-50.000 bunches/harvest. The price of a bunch of Pohpohan is 0,00054 USD. Their income is about 154 USD – 256 USD/month.

Abstract. Hartoyo APP, Khairunnisa S, Pamoengkas P, Solikhin A, Supriyanto, Siregar IZ, Prasetyo LB, Istomo. 2022. Estimating carbon stocks of three traditional agroforestry systems and their relationships with tree diversity and stand density. Biodiversitas 23: 6137-6146. One of the important sectors as a strategy for climate resilience and low carbon development in Indonesia is Forestry and Other Land Uses (FOLU) including the agroforestry sector. Carbon stock and tree diversity in an ecosystem are dynamic over time and still need to be investigated. This study was aimed: i) to estimate aboveground carbon stocks in the traditional agroforestry of Mount Halimun Salak National Park (MHSNP), in Kampung Birang and Kampung Merabu, East Kalimantan, as well as ii) to analyze the correlation between carbon stock with tree diversity and stand density in traditional agroforestry of Mount Halimun Salak National Park (MHSNP), in Kampung Birang and Kampung Merabu, East Kalimantan. The total plots were 75 plots (a plot size of 50x50 m), and carbon stock estimation was focused on pole and tree levels. The average carbon stock in the traditional zone of MHSNP, Kampung Birang, and Kampung Merabu respectively was 51.02 Mg C/ha, 96.25 Mg C/ha, and 82.17 Mg C/ha. The carbon stock in traditional agroforestry of all study sites was very significantly affected by the basal area (m2/ha) (p-val<0.05) with a strong correlation (r = 80% and 97%). The carbon stock was affected by stand density (p-val<0.1) with a very low correlation (r = 27.3%). The carbon stock was very significantly affected by total species (p-val<0.05). However, it had a weak correlation (r = 28.0%). In agroforestry systems, how to manage the agroforestry, socio-economic aspects, ecological site, and market are the main factor in species selection and species maintenance by landowners that indirectly influence biodiversity conservation effort and carbon stock value. The agroforestry system has the potential to become a target and priority location for Indonesia’s FOLU Net Sink 2030 by providing non-timber forest products, which can avoid leakage in forest conservation efforts and carbon stock.

Abstract. Usman AHA, Hartoyo APP, Kusmana C. 2022. The growth performance of Rhizophora apiculata using the cut-propagule method for mangrove rehabilitation in Indonesia. Biodiversitas 23: 6366-6378. A high decrease in the size of Indonesia's mangrove forests requires effective and efficient rehabilitation efforts. One of the efforts is using Rhizophora apiculata as the adaptive and fast-growing mangrove species and its cut-propagule seedling method for accelerating plant propagation. The objectives of this study were to analyze the growth performance of R. apiculata propagules with various treatments of propagule cutting, seedling media, and giving growth regulators (PGR), as well as to determine the best combination of treatment for the growth of R. apiculata. An experimental study was conducted in a greenhouse using a randomized design with 3 factors (propagule cutting, seedling media, and giving PGR) and 3 replications. The interaction of the combination of cut-propagule treatment, planting media, and growth regulator (AxBxC) only had a significant effect on the increase in the number of leaves of R. apiculata. Complete propagules and the lower part of cutting propagules with a combination of mud+sand seedling media and 10,000 ppm PGR (a0b1c1 and a2b1c1) resulted in the best value on the growth of R. apiculata. The cut-propagule seedling method of R. apiculata still showed good growth so it can be used as an alternative to mass vegetative reproduction in mangrove rehabilitation activity.

Abstract. Nugraha LA, Kusmana C, Hartoyo APP. 2024. The growth performance of Kandelia candel hypocotyl cuttings seedlings for mangrove rehabilitation in Indonesia. Biodiversitas 25: 2683-2695. Kandelia candel (L.) Druce is one of the mangrove species threatened with extinction and continues to decline in number yearly in Indonesia. Effective and efficient propagation techniques are urgently needed to reduce the risk of extinction and accelerate the rehabilitation of this mangrove species. This study aimed to analyze the growth performance of K. candel hypocotyl cuttings and determine the best combination treatments. The type of this study was experimentally carried out in a greenhouse. The experimental design was a completely randomized three-factor factorial design with three factors and three replications for each factor: hypocotyl cuttings, planting media, and growth regulators. Based on the variance test resulted in the interaction between the hypocotyl cutting, planting media, and plant growth regulator had a significant effect on seedling height, number of leaves, total weight biomass, sturdiness quotient, and Dickson Quality Index at the 5% test level. The experiment was a success, with all combinations of treatments showing a survival rate of 100%. The best growth of hypocotyl cuttings was found by combining the bottom part of hypocotyl, mud + sand planting media, and a plant growth regulator of 15,000 ppm. The hypocotyl-cutting method can be an alternative method to provide quality seedlings for mangrove rehabilitation activities.

Abstract. Akdah RD, Wijayanto N, Hartoyo APP. 2024. Species composition, stand structure, and carbon stock in the agroforestry system of Wana Lestari Community Forestry, West Nusa Tenggara, Indonesia. Biodiversitas 25: 3350-3358. Climate change is characterized by shifting climate patterns that result in erratic weather phenomena. One of the major consequences of climate change is the reduction in biodiversity and the increased concentration of greenhouse gases (GHGs), primarily carbon. Agroforestry systems (AF) have emerged as a potential solution to mitigate these effects by conversing biodiversity and enhancing carbon stocks. This study aims to analyze the species composition and structure of tree stands and estimate the carbon stock in the AF of the community forest (HKm). The methods used employed included vegetation analysis, stand structure measurement using the Spatially Explicit Individual-based Forest Simulator (SExI-FS), and carbon stock estimation using allometric equations and destructive approaches for seedlings and understory levels. A total of 25 plots, each measuring 20×20 m, were used for data collection. The results show that the species composition in HKm Wana Lestari consists of 63 plant species from 40 families. The highest importance value index (IVI) was recorded for durian (Durio zibethinus Murray) at the pole growth level (90.34%), while coffee (Coffea robusta L.Linden) emerged as the dominant species within the agroforestry system. The diversity index (H') ranged from 0.40 to 2.29, indicating a medium category of diversity. The stand structure did not follow the expected "J" curve pattern. The total biomass and carbon stock across all growth levels were found to be 228.35 and 107.22 tons/ha, respectively. In conclusion, the agroforestry system in HKm Wana Lestari demonstrates notable species diversity and carbon storage potential, although its stand structure deviates from the ideal "J" curve, suggesting opportunities for further forest management improvements.
