Published: April 2022

AbstractClimate change especially in agriculture, have a serious impact on soil fertility. Low soil fertility can affect the quality and quantity of agricultural produce. Biochar is one of the soil-fixing materials that can be used to increase soil fertility i.e. physical, chemical and biological fertility especially in vertisol soil. The purpose of this research was to find out the influence of various types of biochar and the best dose of biochar on the growth of soybean plants. The research was conducted at Screen House, Faculty of Agriculture, Universitas Sebelas Maret, Surakarta on March to June 2021. The research was designed in randomized complete block design (RCBD) with two factors. The first factor is the type of biochar consisting of three levels, which consist of coconut shell biochar, rice husk biochar, and biochar corn cob. The second factor is the biochar dose consisting of five levels, which consist of 0 ton.ha−1, 5 tons.ha−1, 10 tons.ha−1, 15 tons.ha−1, and 20 tons.ha−1. Each experiment was repeated three times. The results showed no interaction between the type and dose of biochar in all variables. Treatment of the type of biochar rice husk with a dose of 20 tons.ha-1 can increase the plant height by 14.6%. Treatment of the type of rice husk biochar with a dose of 15 tons.ha-1 can increase the number of leaves by 11.345%, the number of branches by 36.63%, wet weight by 17.74%, dry weight by 15.9%. Biochar treatment of coconut shell with a dose of 5 tons.ha-1 can increase the leaf area by 63.45%.

Published: April 2022

Abstract

Flickingeria angulata (Blume) A.D.Hawkes is one of the species of orchids found in natural habitats in Wilis Mountain, Ponorogo, East Java. This study was aimed to explore, document, and analyze the diversity of Flickingeria angulata at a natural forest area in Wilis Mountain. The method used is an exploratory method by exploring the forest area in the study site. All data of Flickingeria angulata was recorded including its number, host trees and zone at the host tree where this orchid is attached. The result shows that orchid epiphytic F. angulata was found in 6 host tree species, with the two most important species being Pinus merkusii and Schima wallichii. Zone three (bottom part of the branches) was noted as the most preferred zone at host trees to be attached by Flickingeria angulata. Evaluation of these orchid species in natural habitats needs to be done at the same location to determine the impact of climate change.

Published: April 2022

Abstract
The increased frequency and intensity of flooding and related disasters result from changing climatic conditions and other socio-economic factors. As flooding can be highly destructive and negatively impact human lives, this study attempts to estimate the population, capital stock and disparities in exposure to flooding hazards in Nigeria using GIS and Statistical methodologies. First, the study assessed the spatial distribution of the population and capital stock exposed to flood by utilising population and socio-economic datasets. Then, the distribution of the vulnerable groups affected is estimated by superimposing the population and socio-economic datasets onto the flood hazard maps. The results show that approximately 24.7 million (8.3%) of Nigeria’s Population were exposed to floods in 2015. Most exposed groups were primarily in urban areas irrespective of the income class. Additionally, the clusters of communities within the high-risk flood hazard zones had significantly increased, evident in the number of residents exposed to flood within the 15 years (2000-2015) growing exponentially. These findings further highlight a disturbing state of localities where people are generally less responsive to climate change and natural hazards. Overall, this study provides essential information for disaster risk management and policy formation at different levels of administration and identifies areas where varied and informal strategies are needed to mitigate flood risk and climate change in regions with diverse socio-economic conditions. In addition, this study provides empirical proof of the socio-economic disparities associated with flood exposure in Nigeria and presents valuable insights into the underlying factors.

Abstract
It is necessary to apply modern approaches to prevent the spread/toxic effects of pollution caused by a changing climate; especially metal pollutants to the soil. Thus, the present investigation was aimed to examine chemical speciation of soil samples collected from the River floodplain and its effects on native plant species; Phragmites australis. Synchrotron radiation (SR) tools for Zn speciation in soil and scanning electron microscopy for anatomical changes in plants were applied. Speciation of Zn was a dominant pollutant in Technosols. Two local surroundings were observed for Zn corresponding to its coordination by O and by S, close to ZnS. Whereas, the mixed local surrounding was noted with Zn–S and Zn–O bonds. The analysis of X-ray absorption fine structure results revealed that Technosols contained 70 and 30% of Zn–S and Zn–O bonds, respectively. SR results could be summarized that the main contribution in Technosols was from the authigenic minerals of metals with S: würtzite (hexagonal ZnS), sphalerite (cubic ZnS), bornite (Cu5FeS4), and covellite (CuS). The investigation on growth and modifications in the ultrastructure of P. australis roots and stems showed changes in cellular tissues such as in epidermis and mesoderm, and in subcellular organelles: mitochondria, chloroplast, cell membrane, etc. It is established that the soil contamination with exceeded limits slows down the ontogenetic developments of P. australis. Our findings could provide insight into the physiochemical characteristics of polluted soil as well as information on the toxic effects of pollutants on plants based on non-destructive approaches.

AbstractNitrogen is one of the essential nutrients for rice plants. However, the inappropriate use of nitrogen fertilizers can pollute the environment caused by the loss of N to groundwater and the atmosphere so that it can increase the nitrate content in the soil and greenhouse gas emissions. Therefore, optimal management of N nutrients is needed so that fertilization is in accordance with the needs of rice plants. This research aims to determine the estimation of nitrogen uptake in full organic, semi organic, and conventional rice fields. This research was conducted in Kab. Madiun, East Java. The research was conducted using qualitative, descriptive, and comparative methods as well as survey methods. Soil sampling used a stratified random sampling approach. Nitrogen uptake analysis was carried out by the Kjeldahl method. Data analysis was carried out by T-test. The results showed that the application of a fully organic system had a higher response than a semi organic system to plant biomass. The increase in plant biomass in full organic reached 20.36%, while semi-organic reached 2.91%. The highest tissue N content was in semi-organic. The application of semi-organic was able to increase the N uptake by 11.67% compared to the conventional system, while the full organic system was able to increase the N uptake by 1.87%.

Abstract
Heavy metal pollution from anthropogenic sources is a serious problem for the environment, one of these Pb. Besides industrial waste, the use of chemical fertilizers and pesticides in the agriculture sector can increase heavy metal concentration in the soil. One impact of climate change is the change of rainfall patterns. Some areas suddenly experienced a long drought, forcing farmers to irrigate their fields using industrial wastewater which contains hazardous compounds such as Pb. Bioremediation technology using the plant in combination with microorganisms and organic matter as the bioremediation agent is one way to restore polluted soil as an effort to improve the environment carried out in this study. The purpose of this study was to study the effect of inorganic fertilizers and bioremediation agents on efforts to reduce soil Pb levels with Biduri and the ability of Biduri as Pb hyperaccumulator plants. This study used a factorial experimental design with a completely randomized design with three factors and three replicates. The use of Biduri with a combination of inorganic fertilizers, bioremediation agent, and doses of Pb is able to reduce Pb levels in the soil so that it can be used as an alternative to reduce soil pollution, one of the consequences of climate change which has an impact on agriculture and Biduri in this study have potential as hyperaccumulator plants for Pb.

Abstract
Climate change is causing many environmental problems that impact human health. Extreme environmental conditions affect the immune of the human body. It is easily exposed to the disease. The community takes various precautions to improve the immune system. One of them is to use medicinal plants as an endurance enhancer because some medicinal plants contain immunomodulators. Biduri (Calotropis Gigantea) is one of the medicinal plants that allegedly serves as an immune stimulator or immunosuppressive antibody production. Biduri has not been cultivated by the community, growing wildly. Research using Azolla and mycorrhizal was conducted as an effort to domesticize Biduri and prepare the source of medicinal raw material. The research aims to study the effect of Azolla and mycorrhiza on the vegetative growth of biduri. The study used 5 levels of Azolla, namely 0, 5, 7.5, 10, and 12.5 tons ha−1, and 4 levels mycorrhizal, namely 0, 5, 10, and 15 tons ha−1. Treatment combinations are arranged based on a Randomized Complete Block Design and repeated 6 times. The vegetative growth including the plant height, number of leaves, number of leaves, leaf width, leaf length was measured at 12 weeks after transplanting. The response of vegetative growth on Azolla and mycorrhizal application showed the same pattern, the application of mycorrhizal has not shown a difference in height or development of biduri leaves, while the application of Azolla 12.5 tons ha−1 increases the height of plants and leaves development significantly compared to without Azolla.

Published: April 2022

AbstractPlants have an important role in mitigating climate change because plants are able to absorb carbon dioxide which is one of the greenhouse gases. Good plant growth and high yields are a reflection of its ability to absorb carbon dioxide gas, so various efforts aimed at this, such as fertilization can contribute to reducing greenhouse gas levels in the atmosphere. This research aims to determine the use of liquid organic fertilizers and inorganic fertilizers on nutrient uptake and growth of corn plants. This research was conducted in the Jumantono experimental field, Karanganyar. The research used the Randomized Block Design method, 9 treatments (A = Control, B = NPK standard, C = ¼ NPK + 1 POC, D = ½ NPK + 1 POC, E = ¾ NPK +1 POC, F = 1 NPK + 1 POC, G = ¾ NPK + ¼ POC, H = ¾ NPK + ½ POC, I = ¾ NPK + ¾ POC) with 3 replications, so we get 27 samples. The results showed that the application of liquid organic fertilizer doses of 1/4, 1/2, 3/4 and 1 combined with inorganic fertilizers gave no different results on nutrient uptake and increased plant growth, especially in the number of leaves and stem diameter, but differed in plant height. The application of 1 dose of liquid organic fertilizer and 3/4 dose of inorganic fertilizer gives higher yields compared to standard inorganic fertilizers.
Learning invention using satellite observations to support sustainable development goals (SDG): A use case on disaster risk reduction in Sei Serelo Indonesia
Authors: Setiawan B , Hastuti E W , Saleh E 
Published: April 2022

Abstract
The morphological pattern of the Sei Serelo was investigated to infer the impact of land use and climate change. Two sets of areal Landsat (1990 and 2019) identified the morphological changes to reduce the disaster risk and ideally reverse this prevailing situation. This paper presents a scalable and flexible approach to monitoring land-use change at the local level using various components of the Global Earth Observation System of Systems (GEOSS) platform. Increasing mining area has contributed to land-use change and the loss of agricultural land in many rural areas. In many cases, it worsens the poverty levels of smallholder farmers who depend on subsistence farming – an issue that Sustainable Development Goals number one seeks to address. A multi-criteria evaluation is applied using morphometric indicators, geology, and contours to identify the areas vulnerable to drainage and relief conditions. This learning invention has developed decision tools to apply GIS utilization to support disaster risk reduction. The devices are iterative and can be updated as new events occur to maximize GIS benefit, reducing disaster risk reduction and their potential consequences.

Authors: Shirakawa Hiroaki , Suanpaga Weerakaset 
Published: April 2022

Abstract
There is no doubt about the warming of the climate system, and it is widely accepted by a society that adaptation measures are important to reduce the negative impact of climate change on society. However, there are socio-economic obstacles to the promotion of climate change countermeasures. In other words, to implement climate change adaptation measures, not only the economic efficiency of the measures, but also fairness, consistency with existing policies, and cultural acceptability must be considered. Moreover, future forecasts contain uncertainty. Therefore, it is very difficult to formulate adaptation measures and consider policy priorities. The purpose of the study is to create a web application that shows the risk of natural disasters and the socioeconomic status of the region, targeting Thailand, which is one of the countries affected by climate change to solve the above problems. We basically developed web applications using freeware. As the result, the user can grasp the risk situation of natural disasters in Thailand as a whole, and grasp the industrial structure, agricultural production structure, and poverty situation in each region. This application is expected to promote understanding of the impacts of climate change among stakeholders and to support discussions on policy priorities.

Abstract
Agriculture is one of the sectors affected by climate change. Gunungkidul is one of the areas in Indonesia vulnerable to climate change because most of its population depends on the agricultural sector. Some of the agricultural land in this region is dryland with low food crop productivity. Therefore, research aiming to analyze local food development strategies in hilly areas is necessary. The sample in this study consisted of several households and key figures in three districts of Gunungkidul Regency: Semin, Wonosari, dan Saptosari. Descriptive analysis was applied to identify the potential of local food, consumption, and processed products. The results discovered 11 food commodities in Gunungkidul, encompassing rice, brown rice, cassava, sweet potato, corn, soybean, peanuts, green beans, vegetables, fruits, and animal foods. The strategies are (1) increasing the productivity of local food ingredients, (2) farming assistance in improving the quality of harvested raw materials for local food products, (3) increasing farming technology for local raw material, (4) increasing technology in IKM local food products, (5) massive promotion of local food products, (6) creating a brand identity for superior local food products, (7) developing local food industry groups, (8) massive socialization of food diversification, (9) developing microfinance institutions, and (10) formulating regulations for the use of local food as consumption in agencies or institutions in Gunungkidul. Meanwhile, the priority strategy that should be carried out is to create a brand identity for superior local food products.

Pollution load capacity of the Larangan/Premulung River Sukoharjo Regency, Central Java Province, Indonesia in 2020
Authors: Edi Minarno Purwo , Suprapto Agus , Harsono  
Published: April 2022

Abstract
Climate change has a negative impact on surface water quality. This is influenced by the increase in human activities in the use of water. The resulting water output is discharged directly into water bodies and can increase the pollutant load of river water. One of the recipients of the burden of surface water pollution is the Larangan/Premulung River, which is indicated to have decreased quality due to liquid waste originating from domestic, industrial, and agricultural activities. The purpose of this study was to determine the load carrying capacity of water pollution in the Larangan River in the upstream, middle, and downstream parts. The water samples taken amounted to 10 sample points. The data was collected in the form of physical parameters (flow rate, water temperature, and TSS) and chemical parameters (pH, COD, BOD, and DO). The method of calculating the carrying capacity of the pollution load uses the mass balance method. Data analysis used quantitative descriptive analysis. The results showed that the carrying capacity of the Larangan/Premulung River pollution load: (1) the upstream part could no longer accept the pollutant load in the moderate to the heavy category in the quality standard class II; (2) the middle and downstream parts for COD and BOD parameters are no longer able to accept the pollutant load in the medium to large category.

Abstract
Variations in soil structural and physiochemical properties can impact earth system models related to climate change. However, in most of the countries including Malaysia, soil data are available as low resolution and semi-detailed soil series maps, which hinder their applicability. Therefore, the objective of this study was to develop a framework to compare the conventional soil mapping with digital soil databases and to determine the accuracy of digital soil mapping. Kedah province located in the northern region of Peninsular Malaysia was selected as the study area. Observed soil (Cation exchange capacity – CEC, pH, organic matter as chemical and clay, sand and silt content as physical properties) data published by the Department of Agriculture, Malaysia was compared with SoilGrid (soillgrid.org) dataset. The depths of observed data were harmonised to international standard soil depths as; 0-5, 5-15, 15-30, s30-60, 60-100, and 100-200 cm using the equal quadratic spline approach. Global data were compared with harmonised 16 selected soil series data in Malaysia. Observed soil chemical properties (CEC, pH, and organic carbon) were within the range of SoilGrids data which allows the selected chemical properties to be used where observed data are limited or not available. In contrast, most of the soil physical properties from SoilGrids were not accurate when compared with the observed data. The developed framework in this study can be used to strengthen the accuracy of the available soil data in Earth system models, particularly those that are related to organic carbon and soil structural properties.
