Published: March 2024

Food production in much of the world relies on groundwater resources. In many regions, groundwater levels are declining due to a combination of anthropogenic extraction, localized meteorological and geological characteristics, and climate change. Groundwater in India is characteristic of this global trend, with an agricultural sector that is highly dependent on groundwater and increasingly threatened by extraction far in excess of recharge. The complexity of inputs makes groundwater depletion highly heterogeneous across space and time. However, modeling this heterogeneity has thus far proven difficult. Using two ensemble tree-based regression models, we predict district level seasonal groundwater dynamics to an accuracy of R
2 = 0.4–0.6 and Pearson correlations between 0.6 and 0.8. Further using two high-resolution feature importance methods, we demonstrate that atmospheric humidity, groundwater groundwater-based irrigation, and crop cultivation are the most important predictors of seasonal groundwater dynamics at the district level in India. We further demonstrate a shift in the predictors of groundwater depletion over 1998–2014 that is robustly found between the two feature importance methods, namely increasing importance of deep-well irrigation in Central and Eastern India. These areas coincide with districts where groundwater depletion is most severe. Further analysis shows decreases in crop yields per unit of irrigation over those regions, suggesting decreasing marginal returns for largely increasing quantities of groundwater irrigation used. This analysis demonstrates the public policy value of machine learning models for providing high spatiotemporal accuracy in predicting groundwater depletion, while also highlighting how anthropogenic activity impacts groundwater in India, with consequent implications for productivity and well-being.

Published: March 2024

In the 20th century, with the intensification of human activities, the Earth is experiencing unprecedented warming. However, there are certain differences in the sensitivity of temperature changes to anthropogenic forcings in different regions and at different altitudes of the troposphere. The time of emergence (TOE) is the key point at which the anthropogenic climate change signal exceeds from the internal climate variability serving as a noise. It is a crucial variable for climate change detection, climate prediction and risk assessment. Here, we systematically analyzed the spatiotemporal characteristics of the TOE of temperature changes over the past century by calculating the SNR based on the selected CMIP6 multi-model outputs. The results show that the temperature TOE, particularly in the lower and middle troposphere, shows distinct latitude dependence, displaying an ‘M-type’ distribution from the Antarctic to the Arctic: it first appears in low-latitudes, followed by high-latitudes, and last appears in the two mid latitude bands. For the tropics, the TOE of tropospheric temperatures becomes earlier with increasing altitude: the TOE of air temperatures at the surface, mid-tropospheric 500 hPa and upper-tropospheric 200 hPa occurs in 1980 ± 15, 1965 ± 20, and 1930 ± 30, respectively. The TOEs of tropospheric temperatures in eastern equatorial Pacific are 10–30 years later than those in the western equatorial Pacific. For the regional TOEs of surface air temperature diverse differences exist on land and ocean in various latitudes of two hemispheres.

In urban areas situated along busy waterways like the Yangtze River, the diesel engines of inland navigation ships emerge as significant contributors to air pollution. Among these vessels, certain high-emission ships exhibit considerably higher levels of nitrogen oxides (NOx) emissions compared to others. To effectively identify such ships, this study employed a cost-effective ship emission monitoring sensor platform, comprising high-precision gas sensors, automatic identification system receiver, and sensitive meteorological sensors, along the Yangtze River in Wuhan City. By combining multi-source shore-based monitoring data, we identified ship emission signals and proposed a high-emission ship detection method using inverse modeling. Using this method, we successfully detected inland high-emission ships based on two months of monitoring data. Furthermore, the relationship between different ship types, sizes, speeds, and ship NO
x
emission rates were investigated. The results of this study are beneficial for strengthening the regulation of high-emission vessels in inland waterways, thereby reducing the adverse impact of ship emissions on the environment and climate. It also encourages the inland shipping industry to adopt more environmentally friendly technologies and fuels, as advocated by the International Maritime Organization.

Coastal Demak has a wealth of potential coastal resources because the condition of the Demak coastal area through mapping the potential of capture fisheries reaches 840 tons, and production fisheries reach 1,166 tons. In other aspects, there are conditions of changes in the coastline of accretion and abrasion that affect population activities followed by rob. The majority of the population activities in the Demak coastal area are in the fisheries sector, which, based on the analysis of the typology of the community, the population has a livelihood of fishermen and shrimp paste makers. The main ingredient of shrimp paste is easy to obtain, but shrimp paste makers need help in terms of product innovation and marketing. So, the empowerment of Demak coastal fishing communities needs to be done, one of which is through product branding strategies. The objectives of this research include 1) mapping the potential of coastal Demak; 2) identifying constraints in its development, and 3) finding a suitable empowerment model to improve the economic welfare of the community. Data collection methods include field surveys, structured interviews, and literature studies. Then, the data was analyzed using a qualitative descriptive approach with SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) and mapping. The results showed that: 1) This area is experiencing abrasion; in the morning, the tide reaches a depth of 0.46 - 0.53 meters on the road. The mapping of coastal resources has two forms, namely in the form of aquaculture ponds and marine catches in the high seas, which 5,694 fishermen cultivate; 2) Mobilizing shrimp paste makers to expand market reach by using packaging that is easy to store and prioritizes the principles of hygiene; 3) The development of the Community Empowerment Model based on the results of the SWOT analysis in this study is in Quadrant 1, namely expansion using strengths by utilizing high market demand.

Climate Model is a tool for studying climate and climate change, In climate models there is uncertainty that occurs due to the inability of the model to simulate climate in an area. This study aims to find the best CMIP6 model in the IMC and look at the uncertainty of the model. The data used in this study are precipitation data on the CMIP6 model, as well as the use of CRU data as reference data and observation data. Uncertainty is calculated for historical periods using CDF to see random values from the model. Validation of historical CRU and CMIP6 data is performed by performing statistical calculations that include Pearson correlation, standard deviation, RMSE, KGE, TSS, and relative bias. CRU model testing in Indonesia shows quite good performance at all points, the CRU model has a pattern that follows observational data based on correlation values. the uncertainty of CMIP6 is large in high precipitation and low in moderate precipitation, and there is moderate uncertainty in low precipitation, The analysis of historical data indicates that the EC-Earth3-Veg-LR model has greater performance in simulating precipitation within the IMC region, closely aligning with the values and patterns observed in the CRU model. Furthermore, the EC-Earth3-Veg-LR model displays a strong correlation, as well as good values for the KGE and relative Bias, measuring at 0.33, 0.175, and 1.101% respectively.

One way to mitigate the decrease in shallot production during the off-season is preparing an early warning system and the management of crops planting. This system needs a mathematical model to assist in decision-making. This paper presents a modeling of the relationship between rainfall and planting area and pest attacked area of shallot. The results of the modeling analysis between rainfall and planted area illustrate that an increase of rainfall up to 137.5 mm/month in the lowland area at Brebes, or up to 247.0 mm/month in rainfed or upland area at Garut, is correlated with an increase in the planting area, however then above that rainfall intensity, an increase of rainfall is correlated with a decrease in the planting area. Regression analysis between the Spodoptera exigua attacked the area of the shallot and climate variables illustrates that the attacked area of the shallot decreases if there is an increase in the minimum temperature up to 25.5 °C. Conversely, an increase in the S. exigua attack area of shallot occurs if there is an increase in the duration of solar irradiation of up to 8 hours/day or an increase in a means air humidity of up to 77%. Regression analysis between the Trotol attack area and climate variables illustrates that the Trotol attack area decreases if there is an increase in the average wind speed of up to 5.7 knots. Conversely, an increase in the attacked area of Trotol occurs if there is an increase in rainfall of up to 205 mm/month or an increase in a means air temperature of up to 29.0 °C. This illustrates that climate conditions that are sunny, cool, dry, and calm can reduce the area of attack by S. exigua and Trotol. The threshold values obtained through the above analysis are then used in decision support in the EWS SIPANTARA, namely the Early Warning System and Planting Schedules Management for Horticulture.

Semarang City, situated along the northern coastal region of Java Island, Indonesia, grapples annually with the dual challenges of tidal flooding and urban inundation. Establishing a comprehensive flood disaster zoning for both tidal floods and urban inundation to identify priority areas for effective flood mitigation and reducing disaster risk. This study aims to assess the potential inundation of tidal floods, urban floods, and their combined impact on Semarang City, using an integrated approach that combines Geographic Information System (GIS) technology with the Analytic Hierarchy Process (AHP). By leveraging data from Digital Elevation Model Nasional (DEMNAS), Google Earth, Rupa Bumi Indonesia (RBI) maps, and the Open Street Map (OSM) database, we obtained elevation, landcover, distance to the river, buildings, and administration data, which were used as criteria in the analysis. The research findings unveil three distinct flood inundation scenarios within Semarang City: tidal floods, urban floods, and a combination of both. Each scenario is categorized into low, medium, and high levels of inundation, providing a granular assessment of flood risk across the city. Importantly, the study extends beyond spatial analysis to evaluate the impact of inundation on affected buildings. The results indicate that the area inundated by the combination of tidal and urban floods is as follows: 86.87% high inundation, 13.12% moderate inundation, and 0.01% low inundation.

Local disaster knowledge plays an essential role in efforts to reduce disaster risk. Meaningful lessons about post-disaster coping mechanisms cover a lot of traditional experience and knowledge regarding warning signs and evacuation sites. However, the changing nature of the eruption and the enormous impact in 2021 resulted in a heavy loss of life due to a lack of local knowledge and disaster awareness. This study aims to analyze local disaster knowledge on disaster risk reduction in Disaster Prone Area III (KRB III) of Semeru Volcano. This study uses a quantitative and qualitative approach with data collection techniques through surveys, observations, and in-depth interviews. The survey was conducted among 30 residents affected by the eruption of Mount Semeru. Respondents completed a questionnaire about their knowledge and actions taken when Mount Semeru erupted. Furthermore, in-depth interviews were conducted with several key figures in the field, including 1) Oro-Oro Ombo village officials; 2) the Volcano Observation Post at Mount Sawur; 3) the Head of BPBD Field Post, Curah Kobokan; and 4) the Regional Disaster Management Agency in Lumajang Regency. The aspects assessed are aspects of triggers, impacts, and forms of disaster mitigation carried out. The research results show that the public’s limited knowledge regarding the unpredictable characteristics of Mount Semeru’s eruption and which locations are safe to pass through is the cause of the large number of fatalities. The level of local disaster knowledge is directly proportional to the distribution of education and transportation facilities in Candipuro and Pronojiwo sub-districts. Belief in God causes good mental resilience so that people do not continue to be pushed down by circumstances.

Published: March 2024

The increase in global tourist activities triggers the emergence of physical change phenomena known as tourism gentrification. This phenomenon is famous for its negative impact, especially on low-income people, until this process is considered a cascading hazard from disaster. Unfortunately, researchers find difficulties when trying to start research on this topic due to the absence of an overview of research trends in bibliometric studies. This research uses bibliometric analysis to analyse the effect and significance of the nations, publications, organizations, and authors that have contributed the most to this subject matter. The Scopus database was used to collect bibliographic information on pertinent studies. The selection process resulted in choosing a total of 220 articles that were published between 1990 and 2023. A bibliometric study of these publications was carried out using VOSviewer version 1.6.19 as the primary software application. Regarding tourism gentrification, the most prolific institution was located in Portugal, Universidade de Lisboa, while the most productive journal is Sustainability (Switzerland). The most prosperous nation in terms of production and cooperation was Spain. The effects of tourism gentrification, including over-tourism and touristification, have been the primary focus of research published in recent years. The link between tourism development or planning and the tourism gentrification process needs to be examined.

Published: March 2024

The expansion of human activities, driven by population growth and various societal needs, has led to significant land-use changes, resulting in microclimate modifications. These changes have a crucial impact on land surface temperature (LST), particularly in urban areas. Urbanization, transportation, industrialization, and urban settlements are the main factors contributing to LST variations. This study focuses on the distribution of industries and their influence on land surface temperature in Sukoharjo Regency, Central Java, during the years 2001, 2009, and 2021. The research utilizes Landsat satellite imagery to analyze the industrial distribution and LST in the study area. The images were acquired on August 27, 2001, June 14, 2009, and July 25, 2021. The methodology includes land-use classification, LST extraction, and regression analysis to assess the relationship between industrial land area and land surface temperature. The results show a significant increase in the number of industries in Sukoharjo Regency over the studied period, with a growth rate of over 100% from 2001 to 2010 and further expansion until 2021. The industrial areas exhibited a clear spatial distribution in all years, indicating the impact of industrialization on land use. The regression analysis revealed a relationship between the industrial land area and land surface temperature, suggesting that expanding industries contributes to higher land surface temperatures. These findings provide valuable insights for urban planning and environmental management in Sukoharjo Regency to mitigate the impacts of climate change and promote sustainable development.

Authors: Partini Dwi , Hidayaht Achmad Nur
Published: March 2024

Indonesia is a country that is prone to natural disasters, such as earthquakes, floods, volcanic eruptions and tsunamis. To reduce the risk of disasters, efforts through education are important. This article aims to conduct a literature review regarding disaster risk reduction through education in Indonesia. Education has an important role in increasing public awareness, increasing knowledge, and developing the skills needed to reduce the impact of disasters and increase responsiveness in dealing with them. This research wants to find out other forms of approaches that have been implemented to reduce disaster risk in education in Indonesia and find out what the results are. A review of existing literature shows that there are 3 efforts to reduce disaster risk through education, namely formal education, informal education and non-formal education. The research results show that the three educational pathways are implemented quite well in Indonesia. Forms of disaster risk reduction through education include integration of learning in schools, local wisdom, training, outreach and disaster mitigation simulations from disaster awareness activist groups and from certain institutions/institutions to the community, as well as disaster mitigation programs from community groups themselves. To reduce disaster risk in Indonesia, sustainable and coordinated efforts are needed between the government, educational institutions and the community. Increasing the role of education in protecting and preparing people for disasters is important to minimize the negative impacts of disasters in the future.

Large wood remobilization in Asakura (North Kyushu, Japan): Adapting strategies to climate change and rural population depletion
Authors: Gomez C , Shimizu M , Kinoshita H
Published: March 2024

In the aftermath of the heavy rainfall events of 2017 in North Kyushu, Asakura (Japan), driftwood-related disaster risk has proven to be as real as it was in 1933, when wood-laden debris-flow invaded the city centre of Kobe City near Sannomiya station. Despite a temporary truce obtained thanks to extensive Sabo dam constructions, climate change, the return of forest on agricultural land due to rural exodus and an ageing population are once again increasing driftwood hazard and disaster risk. In the face of these novel challenges, new management strategies may need to be considered, and the present contribution aims to propose a new approach to driftwood hazards and disaster risk. For this purpose, the present contribution is analysing the 2D hydrodynamic of scenario-based floods on driftwood deposited after the 2017 heavy-rainfall event in Asakura. The boundary conditions for the simulation were generated using UAV photogrammetry calibrated against existing DEM data to generate a DEM at 25 cm horizontal resolution and an orthophotographs at 5 cm resolution. The results show that with the new river configuration (post-2017), an instantaneous peak flow of 90 m3/s is necessary to flood the areas where the driftwood has stopped with a water depth of >40 cm. This is 9 times the mode discharge calculated from the inlet geometry. The majority of the driftwood is thus not an immediate hazard, and leaving the wood instead of removing it should be considered as a management strategy whenever it is feasible. Recent research in Western Europe and Northern America has already shown the importance of driftwood for biodiversity and wildlife, and combining both environmental and hazards and disaster risk objectives may be a solution. For this purpose, the authors propose that medium-size ditch and artificial “abandoned channels” could be created in order to trap the wood in the floodplain, so that the cost from removing the wood can be alleviated, horizontal trapping could complement vertical trapping at slit dams, and the local wildlife could benefit from the wood decomposition in the floodplain.

Increased population growth is one of the driving factors for land use change because it is to meet the needs of the population, especially in settlements or residences. Land use changes occur as a result of improving the quality of human life which has an impact on land use changes that are difficult to control. This study aims to analyze the distribution of land use in 2013 and 2022, and analyze the relationship between population density and land use change. The research method used is the Overlay Method and Liner Regression. The results of this study show that land use change in Karangmalang Subdistrict in 2013 and 2022 amounted to 197.7 hectares, dominated by residential land of 154.4 hectares. There was an increase in population in 2013 and 2022 of 2,280 people/square kilometer. The results of the linear regression calculation show an R2 value of 0.697 which means that there is a positive relationship between land use change and an increase in population density.

Authors: Albayani Thoriq , Fikriyah Vidya N.
Published: March 2024

Many factors drive land use and land cover change (LULC) including biophysical and socio-economic conditions. Since Ngawi Regency is one of the areas passed by the toll road, in this study we selected Ngawi as the study area to provide an understanding of the land use/cover dynamics caused by economic factors. This study aims to (1) analyse the distribution of land use/cover change before and after the toll road exists and (2) investigate its relationship with population growth. Data on land use/cover was visually interpreted from satellite imageries (2012 and 2020). Population data was taken from the regional statistics bureau. LULC was detected using a Geographic Information System (GIS). The results show that rice fields dominated land use (44.43% and 42.71% of all existing land use in 2012 and 2020, respectively). A land conversion from a rice field to a toll road has been observed covering 45.45 Ha. Although there was an increase in population from 2012 to 2015, the population number gradually decreased from 2016 to 2020. This result indicates that despite the existence of a toll road, it has less relation to the population dynamic in the study area in which other factors may play a role.

The Sub-District of Giriwoyo, located on the southern edge of Wonogiri District, is classified as an agricultural land. This subdistrict is located in the Keduang sub-watershed. This geographical condition makes this subdistrict extremely vulnerable to flooding. This research seeks to determine the distribution of flood-prone areas and categorize the level of flood vulnerability in the Wonogiri Regency, with Giriwoyo as a research site. Quantitative descriptive research employs a scoring procedure based on environmental conditions-related scoring parameters. These variables include slope, soil type, rainfall, altitude, land use, and buffers for river flow. The measured parameters are then layered in a geographic information system (GIS) application to generate a flood vulnerability map. The data analysis procedure employed a descriptive approach. The results indicate that the dispersed, areas of Giriwoyo are classified into 4 vulnerability catogeries such as not vulnerable, vulnerable enough, vulnerable and very vulnerable. Areas with vulnerable categories are scattered throughout the giriwoyo area which is dominated by rice fields and settlements with a flat slope. The very vulnerable area dominates the western part of the giriwoyo which has a lower elevation and flat slope. The parts of giriwoyo that are not prone to flooding are in Selomarto, Tukulrejo, and Girikikis.

Birobuli is located South Palu, Indonesia. In Indonesia, earthquakes are frequent events. Consequently, it is crucial to consider the safety of building structures against earthquakes when calculating the factor of safety of the building. It is important to not only analyse the impact of earthquakes on the superstructure but also take into account their effect on the substructure. One potential substructure failure caused by earthquakes is soil liquefaction, which refers to a decrease in soil bearing capacity resulting from seismic activity. To assess this phenomenon, a quantitative approach was employed in this study, involving soil investigations and sampling from the field. The findings from the soil investigation were used to calculate the susceptibility of soil liquefaction in different soil layers and the axial bearing capacity of single pile foundations both before and during earthquake and liquefaction. The study site predominantly consisted of silty sand with ground water table (GWT) level at -4m with low CPT value, making it susceptible to liquefaction from depths ranging between -4 meters and -12 meters. Two single pile models were simulated in the study, with respective reductions in their axial pile bearing capacity of 71,6% and 38,9%

The map is a complete picture of phenomena in a particular area or location within a certain period. It can explain the distribution, interactions, and associations that occur. Success in reading maps is required for two things, namely, the quality of the map and the competence of map readers. This study analyzed students’ ability to read maps of Merapi Volcano hazardous areas by students at SMA Negeri 1 Cangkringan, Sleman Regency. This study used a quantitative approach using primary data obtained through tests. This study used a non-probability sampling technique with a sample of 64 students of class XI Social Sciences at SMA Negeri 1 Cangkringan. The analysis technique used was descriptive statistical analysis. The results showed that the level of ability to read the Merapi Volcano hazard map by students at SMA Negeri 1 Cangkringan 14 students (21.9%) belonged to the moderate category, and 50 students (78.1%) were in the high category. Therefore, the average score for the student’s ability to read the Merapi Hazardous map was 76.23 (moderate category). The results of the ability to read maps when viewed by gender showed that out of 28 male students, six students (21.4%) belonged to the moderate category, and 22 students (78.6%) were in the high category. Meanwhile, for female students, there were eight students (22.2%) in the moderate category, and 28 students (78.8%) were in the high category.

Published: March 2024

Toll road construction is a vital infrastructure connecting the two economic centers on Java Island. However, given the potential disaster risks in the region, it is essential to assess the geological and geotechnical conditions to determine the potential for liquefaction in the area. The special region of Yogyakarta is susceptible to earthquakes and associated disasters. One of the most significant earthquakes occurred on May 27, 2006 with a magnitude of 6.3 Mw resulting from the Opak Fault. Furthermore, the toll road is constructed above the Mataram Irrigation Canal, characterized by a shallow groundwater level and young volcanic deposits that are vulnerable to liquified. The study aimed to determine the potential for liquefaction in the area and predicted the vertical settlement caused by liquified soil. The analysis of liquefaction potential utilized the simplified procedure to obtain factor of safety and Liquefaction Severity Index (LSI) to assess the vulnerability index of liquefaction. Results indicated the research area had a very low to medium liquefaction susceptibility index. In addition, the calculation of vertical settlement using Idriss and Boulanger (2008) equation showed a predicted vertical settlement range of 0.4 cm – 44.64 cm. The predicted vertical settlement range underscores the importance of considering the potential for liquefaction to mitigate any adverse effects on the toll road’s construction and operation.

Disaster mitigation studies with a geographical, social and cultural approach can be carried out on a system of place names known as toponymy. Toponomy generally has a relationship with the characteristics of the region. Sumberagung Village, located in Pracimantoro District, Wonogiri Regency, Central Java, has a unique character as a karst area. This study aims to analyze the toponymy of Sumberagung Village which is related to the spatial, social, and cultural context as a study of disaster mitigation in the region. The research method uses descriptive qualitative analysis with interview techniques, documentation and field surveys. The results of the study show that the Toponymy of Sumberagung Village contradicts the factual conditions of the environment. The name “Sumberagung” which means a large water source has the characteristics of an area that is prone to drought. The history of the name Sumberagung Village comes from deep contemplation, prayer and hope to find a large source of water that can be used in mitigating drought. The expectation of a large supply of water forces the community and the government to make efforts which are manifested as policies, tracing karts water sources that are below the surface, and providing water resources infrastructure. These efforts show that toponymy indirectly has a relationship with disaster mitigation in Sumberagung Village.

Published: March 2024

To protect natural resources and maintain the normal functioning of hydrological processes, the upper slope of the Manguan Sub-watershed should be designated as a conservation area. However, agricultural activities in the upstream have disrupted the watershed’s hydrological function, triggering high rates of erosion, sedimentation, and flooding. The aim of this research was to estimate the level of erosion hazard on Manguan Sub-watershed’s Upper Slope and its conservation directives to mitigate it. This study adopted a land unit approach to flow occurrence land units with the prediction of MUSLE (Modified Universal Soil Loss Equation) by integrating rainfall and run-off erosivity. The direction of land conservation will be evaluated through the perspectives of land rehabilitation and soil conservation. Based on the result, the prediction of erosion hazard levels is classified into four groups: Low, Moderate, High, and Extremely High. The Manguan Sub-Watershed’s Upper Slope has a significantly high level of erosion and necessitates soil conservation improvement measures on approximately 79% of its area.

Located in Purworejo Regency, Pituruh is an area that prone to a landslide. Disaster mapping was a strategy that has been done so far by the government institutions and academia. According to its topography, Purworejo has been dominated by slope with more than 30 degree. The creation of landslide vulnerability map was carried out through several stages, namely, calculating rainfall at 6 stations located in Pituruh district, then producing average rainfall data to be used as a reference to create a rainfall map, then overlay process. Referring to the 4 parameters used, slope became an important parameter to determine the level of landslide vulnerability in Pituruh. The development of Geographic Information Systems can provide various types of spatial data related to the earth’s surface, and has the ability to perform accurate spatial analysis. Mitigation aims to reduce risks that have the potential to become disasters or reduce the effects of disasters. This study represents the level of vulnerability in Pituruh district by classifying the existing level. The results of this study have 5 classifications with different areas, namely highly vulnerable that covers 240.27 ha, moderately vulnerable for about 2237.81 ha, moderate with 3322.68 ha, vulnerable by 3040.14 ha, and not vulnerable area of 24.72 ha.

Oil palm biomass is one of the most abundant wastes in Indonesia. The biomass can be used as fertilizer for increasing plant growth, such as paddy Inpara-2 variety and peatland rehabilitation. The study on the application of oil palm biomass as fertilizer on paddy Inpara-2 growth and its potency in agroforestry systems for accelerating peatland rehabilitation is limited. This study aimed to analyze the application of oil palm-based fertilizers on paddy Inpara-2 and investigate the scientific literature on the use of oil palm biomass as fertilizer in agroforestry systems for peatland rehabilitation. The method used was a completely randomized design with a factor (oil palm-based fertilizer) and scientific literature from the search engine database. Application of micro-lignocellulose 1% resulted in the best paddy germination percentage (100%), abnormal sprout percentage (0%), maximum growth potential (100%), mean germination time (1.95 days), seedling survival rate (100%), and seedling height (13.67 cm). We found 993 articles on oil palm biomass as fertilizer in supporting peatland rehabilitation and only three articles (0.003%) used the agroforestry system as the selected approach. Application of oil palm biomass as fertilizers can accelerate paddy Inpara-2 variety growth, and agroforestry system application could accelerate peatland rehabilitation.
