Abstract
Central Java province has the highest disaster risk index (score 203) of 33 provinces in Indonesia. In 2022, the Province was most affected by floods with 203 incidents. Kudus Regency is one of the regencies in Central Java that is often affected by floods. Mejobo sub-district is the sub-district with the most flood events in the last 5 years. The frequent occurrence of floods triggers various emerging problems such as social vulnerability. Hence, the purpose of this study is to examine social vulnerability and population analysis in the Mejobo sub-district. The calculation of vulnerability classes uses 5 parameters, namely population density, people with disabilities, vulnerable age groups, poor people, and women. which is then scored for each parameter and classified into 3 vulnerability classes (low, middle, and high vulnerability). The results obtained for low vulnerability were found in 3 villages, namely Jojo, Temulus, and Tenggeles Villages. Moderate vulnerability is in the villages of Hadiwarno, Kirig, and Mejobo. In the high vulnerability class, there are 5 villages, namely Golantepus, Jepang, Gulang, Kesambi, and Payaman.

Abstract
Indonesia has a long history of social forestry (SF). The essence of this scheme is to involve the community in managing state forests. The agroforestry system is the main choice, with trees already on forest land. The combination of trees and crops provides an alternative livelihood for the community. Coffee plants are one of the choices for undergrowth plants. This study aims to explain the management of coffee agroforestry in social forestry programs. The method used was direct observation in the field combined with a focus group discussion involving six Forest Village Community Institutions (LMDH) with 15 respondents for each LMDH. The results showed that farmers mainly chose coffee because it was shade-tolerant, allowing it to grow well under tree stands. Coffee management in SF with an agroforestry system differs from a monoculture cultivation system in terms of spacing, number of coffee plants per hectare, land preparation techniques, planting, maintenance, and productivity. The government can encourage the management of coffee agroforestry systems in state forests through social forestry schemes by providing training and facilities to increase the added value of coffee in advanced products, providing access to production facilities, capital, and markets, and institutionally strengthening farmer groups.

Published: March 2024

Abstract
Agroforestry technology in forest area land management aims to increase land productivity sustainably. The aims of the study were to: (1) examine the effect of compost from leaf litter on three different tree species on the growth of arrowroot seedlings, (2) examine differences in arrowroot growth given various types of compost from leaf litter on three different tree species, and (3) to determine the best type of leaf litter compost for the growth of arrowroot seedlings. Observations were made on plant height, number of leaves, clumps, tuber productivity, and total dry weight in 20 observation units using a completely randomized design (CRD). The research data were then analyzed for variance. Then if there were significant differences, the DMRT (Duncan Multiple Range Test) follow-up test was continued. The results showed that the use of compost had a considerable effect on plant height and number of leaves. However, compost did not affect the number of clumps, total dry weight, and arrowroot tuber productivity. The results showed that gamal compost had the highest tuber productivity, namely 37.73 gr/plant, followed by lamtoro compost at 33.98 gr/plant, and calliandra compost at 23.05 gr/plant.

Abstract

Araucaria cunninghamii is a coniferous tree that has high commercial value for tropical and sub-tropical regions and is used as an alternative raw material for the pulp and paper industry. In order to get a good yield from this species, a progeny test was established in Bondowoso, East Java, and the variation in growth was investigated. This trial included 6 populations, 80 families, and 4 replications of 4-tree row plots spaced 4 m x 2 m. A range of percent survival of 98.81%–99.41%, with an average of 99.20%, was reported for adaptability, showing no significant variations between populations or between families. Significant differences existed between populations and between families in terms of growth in height, diameter, and volume. The best diameter was from the Manokwari population (4.93 cm), while the best height and volume characteristics were from the Jayapura population (5.32 m; 0.0051 m3). Height, diameter, and volume characters have moderate to high heritabilities. The genetic and phenotypic relationships between height and diameter, height and volume, and diameter and volume features were all high and positive. With the family selected at a 30% proportion, the predicted genetic gain for height, diameter, and volume were 3.14%, 5.79%, and 0.00073%, respectively.

Abstract
As a bioindicator of soil quality and controller of soil dynamic (fertility), soil fauna is influenced by various environmental factors like climate and edaphic elements. This research aimed to examine the abundance of soil fauna in a lower montane forest ecosystem at different elevations and analysed how the environment affects their abudance. The study used purposive sampling in Gunung Halimun Salak National Park, specifically at altitude of 1,100 masl; 1,200 masl; 1,300 masl; and an open area (1,230 masl) as a control. LSD test revealed a significant difference on soil fauna abundance between the 1,100 masl elevation and the control group. However, there was no significant difference of soil fauna abundance between altitude of 1,200 masl and 1,300 masl. The highest abundance of soil fauna was found at 1,100 masl, with 156 individual/m2. Conversely, the lowest abundance of soil fauna was recorded in the open area at 1,230 masl, with 3 individual/m2. The Pearson correlation analysis showed that soil fauna had positive correlation with light intensity and air temperature, and negative correlation with air humidity. Furthermore, Soil fauna abundance had also positive correlation with edaphic parameters (CEC, C-org., litter weight, soil respiration, porosity, and soil temperature, except soil pH and bulk density.

Abstract
Microplastic contamination of soil is increasingly impacting soil performance in agriculture. This research studied the relationship between microplastic contamination with the physical properties of Inceptisols at different slopes in the horticultural production center of Banuhampu, Agam, West Sumatra. The determination of soil samples was carried out by purposive random sampling with a quantitative survey method. Sample testing using randomized completely block design (RCBD) with five treatments and three replications: 25-45% in forests and 0-8%, 8-15%, 15-25%, and 25-45% in fields at a depth of 0-20 cm. Characteristics of physical properties of Inceptisols contaminated with microplastics have a moisture content of 31.69%, a bulk density of 0.78 g cm−3, a total pore space of 70.67% (without considering the importance of soil organic matter), and a soil texture class of sandy loam (68.19% sand, 19.55% silt, and 12.26% clay). The value of microplastic concentration in Inceptisols was 438.33 particles kg−1. The slope does not significantly affect the physical properties of Inceptisols contaminated with microplastics. The effect of microplastic contamination has a significant relationship with the physical properties of Inceptisols, namely clay with a value of r = 0.650** and a linear equation: Microplastic = 15.474 (Clay) + 248.57; R2 = 0.4228.

Published: March 2024

AbstractThe Jasinga Silviculture Teaching Industry (JSTI) area is a research forest with ecosystem conditions that have yet to be widely known. Research on the local ecosystem is needed, especially regarding vegetation, soil, and the hydrological cycle. Vegetation densities in the JSTI area are uneven, which affects groundwater absorption (infiltration rate). This study aimed to identify the infiltration rate and soil physical properties at different vegetation densities. The research plot was determined through purposive sampling techniques based on the level of vegetation density. The research methods carried out were analysis of vegetation density and composition, identification of soil physical properties (such as organic matter content, bulk density, porosity, and moisture content), measuring field infiltration rates using a double-ring infiltrometer, and analyzed the Spearman correlation. The results showed that dense vegetation has the highest score of organic matter content (> 4%), the bulk density is moderate, the porous category dominates the porosity, and the water content and infiltration rate were greater than sparse vegetation plots. Therefore, it is recommended to carry out planting activities at sparse vegetation density in the JSTI area.

Abstract
Undoubtedly, the agroforestry system is the best land use strategy. Still, if it is linked to the success of land rehabilitation, it needs to be re-examined, especially in cases of rapid deforestation. The agroforestry in rehabilitation activities will contribute to the FOLU carbon net sink as one of the climate crisis mitigation programs to support government goals. This research was conducted at Register 38 of Gunung Balak using a qualitative approach through case studies. In-depth interviews were conducted with key informants to obtain data and information. The long struggle for restoring the protected forest area registers 38 of Gunung Balak through various policies ranging from coercion to persuasion, but facing various obstacles has made success very difficult. BPDAS Way Sekampung Way Seputih, in collaboration with the Forestry Service, has recently made breakthroughs in rehabilitating land. In recent years, new ideas on productive and sustainable agro-forestry patterns, with local communities as key stakeholders, are bringing economic, social, and environmental benefits to local communities. This success is expected to help pioneer forest restoration elsewhere.

Abstract
Jatinangor district, located in Sumedang regency, is experiencing forest degradation due to rapid development spurred by its designation as a transport hub between Bandung, Garut, and Sumedang. In order to facilitate more environmentally sustainable developments in Jatinangor, approaches involving local communities in land rehabilitation is essential. One such proposal is the development of 8.18 ha of land in Jatiroke Village. In collaboration with Jatiroke locals and Geulis Mountain Communications Forum (GMCF) and PT. Kahatex, the land is planned to be transformed into a green open space for ecotourism complex based on the DEWA (Desa Edukasi Wisata Agro or Agro-tourism Educational Village) concept ensuring sustained benefits for the environment and the local populace. The complex is planned to have intensive and non-intensive zones. The intensive zone facilitates the visitors and supporting utilities while the non-intensive zone facilitates vegetation cultivation. The area’s planned main conservation facility is the Arboretum of Textile Dyeing Trees which hosts 20 tree species, 2 bush species, and 4 herb species traditionally used as dyes and are native to Western Java. This forest restoration project, involving collaboration with villagers and a corporation, is slated to exemplify the importance of environmental sustainability through ecotourism and education for all involved.

Abstract
Forest and land fires are one of the main environmental challenges in Riau, that majority of its land covered by peatland. Therefore, the main challenge is to introduce fire-free alternatives to clearing agricultural land, while recognizing that local people lack the resources, knowledge, and technology on potential alternatives to zero-burning agriculture. A community-based business model for fire prevention and peatland restoration is urgently needed by making the community the main actor capable of generating value. This study aims to develop the alternative livelihood to support peatland restoration through Sustainable Business Model for the Community (SBMC) by applying Participatory Action Research (PAR). We conducted surveys, focus group discussions (FGDs), and field interviews as well as implemented Canvas Business Model (CBM) to identify the business component. Our finding showed that community groups were able to develop an agrosilvofishery business model that not only implement sustainable practices for land preparation without fire but also determined varieties of commodities that are ecologically and economically suitable for agroforestry techniques on peatlands. Hence, CBM is a suitable tool that helps in developing an integrated sustainable business model for community and can be applied in participative setting. CBM also ensured equity by identifying and agreeing on a cost structure and benefit sharing.

Abstract
Forest and land fires in indonesia occur almost every year, one of the districts that often experience forest and land fires is Ogan Komering Ilir District, South Sumatra Province. One indicator of forest and land fires is hotspots. This study aims to create a classification model for the forest and land fire risk in Ogan Komering Ilir District using four attributes, namely hotspot density, distance to rivers, distance to settlements, and distance to roads. The decision tree C5.0 algorithm is used to develop a classification model. The decision tree C5.0 produces a model that can be used to classify new data based on the rules formed by the tree. The results of modeling using C5.0 with 80% training data and 20% test data show that the performance of the model can correctly classify around 86.49% of the total sample in the data. This shows that the model has a relatively high level of accuracy in classifying. The modeling decision tree shows that forest and land fires are most affected by distance to settlements

Published: March 2024

Abstract
Analyzing the fuel characteristics of a forest is essential when creating fire danger rating system (FDRS) and understanding how forest fires behave. In this study, the researchers predicted the intensity of forest fires by examining the amount of fuel present Berbak and Sembilang Natinal Park between November 2020 and December 2021. The fuel load measurement was carried out on surface fuel in the burned peatland area by modifying the line-intersect method (triangular plot - Van Wanger 1982) and the method developed during the Kalimantan Forest Climate Project (KFCP). We assessed the possibility of forest fires occurring, based on the fuel conditions. Variations were found in the fuel quantity and composition on the forest’s surface layer across different regions. Consequently, the intensity and type of forest fires changed accordingly. The Berbak Sembilang National Park area proved more intense surface fires. These results underscore the importance of understanding regional fuel characteristics and analyzing the predicted intensity and type of forest fires to take timely preventive measures against early fire occurrences.

Authors: Afifah R , Wulandari A S , Tambunan I R 
Published: March 2024

Abstract
Parica culture has the potential to overcome problems in parica seed germination. One factor that influences the successful initiation of parica culture is the process of sterilization and pre-treatment in the form of breaking seed dormancy. This paper aims to analyze the effect of the immersion time of parica seeds on the germination rate of parica seeds. The explants used were parica seeds with a size of ± 2 cm. Seeds are given pre-treatment, the seeds are immersed in hot water at around 70°C for 10 minutes, the immersion time in hot water is 3, 6, 12, and 24 hours according to treatment. The variables observed were the first time the parica seeds germinated, the percentage of germinated seeds, the percentage of contamination (fungi, bacteria), and the percentage of browning. The results showed that the immersion time for pre-treatment affected the success of parica seed initiation, especially seed germination. The 3-hour immersion treatment used resulted in the highest germination of parica seeds (55%) and significantly differed from the germination rates in other immersion times. Based on the high germination rate and low level of contamination, this becomes prospectively to provide optimal in vitro parica germination.
