Abstract

Mycorrhiza is a form of mutualistic symbiosis between plant roots (rhiza) and fungi (mykes). Plants will get various kinds of nutrients, especially phosphorus (P) from their mycorrhiza, while mycorrhiza will get carbon (C) from plants. Phosphorus is a macro nutrient that plants must have. Phosphorus has important functions in plants, namely during respiration, photosynthesis, energy transport, energy storage, cell enlargement, cell division, as well as processes within plants, stimulating plant root development and germination. Mycorrhiza is grouped into three types, namely ectendomycorrhiza, ectomycorrhiza, and endomycorrhiza. This journal review uses the SLR or Systematic Literature Review method with the aim of knowing the meaning of mycorrhiza, characteristics, enzymes that play a role, the mechanism of phosphorus absorption in mycorrhiza, mycorrhizal colonization, and mycorrhizal symbiosis in cassava plants. This article discusses mycorrhiza, one of the mycorrhizal genera, namely Acaulospora, which is included in the endomycorrhiza or Vesicular Arbuscular Mycorrhiza (VAM). The spores are characterized by a brownish yellow color and a rough surface like orange peel. The phosphatase enzyme is produced by Acaulospora hyphae. This enzyme helps increase the amount of P nutrients that are useful for plants by releasing the fixation of P nutrients from Al, Fe, and Ca in the soil, so that phosphate elements are available to plants.

Abstract

Population growth and urbanization pose challenges in maintaining sufficient land carrying capacity. This research aims to analyze land carrying capacity and urban development in Sirimau District, Ambon City. Data collection methods involve direct observation and document collection. Data analysis utilizes a quantitative descriptive approach and spatial analysis with overlays of relevant parameters. The results show that the most significant growth occurs in Batu Merah Village. Land carrying capacity calculations reveal an average decrease in residential land carrying capacity. In 2022, Ahusen Village, Rijali Village, and Galala Village recorded a decrease in land carrying capacity below 1, indicating that these areas can no longer accommodate the population residing there. This suggests that population pressure and unchecked urban growth negatively impact land carrying capacity. Sustainable management measures, such as prudent urban spatial planning, protection of green areas, and appropriate infrastructure development, must be implemented.

Abstract

Former solid waste disposal at Talang Gulo TPA Jambi City implements a waste management system using a controlled landfill. Leachate and rainwater absorb into the soil and accumulate to become polluted groundwater. Furthermore, the polluted water flows into the dug well water and can reduce the quality of the dug well water. The aim of this study is to determine the heavy metal pollution index of residents' dug well water and the influence of the distance between the ex-TPA and dug well water. This research method is purposive sampling based on the distance of heavy metal sample points, namely 70 m, 230 m and 300 m. Sample analysis used an Atomic Absorption Spectrophometer (AAS) in the laboratory. The results were classed and indexed (C/P), the groundwater was very lightly contaminated with Cd (<0.1), heavily contaminated with Fe (0.51-0.75), very lightly contaminated with Cr (<0.1), and moderately contaminated with Cu (0.26-0.50). Based on the R value of the four metals, it shows that there was a very high influence between the distance between the well water sample and the former solid waste disposal leachate product.

Abstract

The plantation sector, especially tobacco plants, is the biggest contributor to the country's foreign exchange value non-mining through tobacco excise and export. With the increasing number of active smokers in Indonesia, the need for tobacco continues to increase, emphasizing the role of this crop in the economy and providing large profits for farmers. However, along with the growing issue of land use change, recently many tobacco plants have been planted on unsuitable land. The research was conducted on all rice fields in Bondowoso Regency from October 2022 to March 2023. The land suitability evaluation method was used to assess land characteristics that affect tobacco plant growth. The parameters used were soil pH, soil texture, C-organic, electrical conductivity, cations bases (K, Ca, Na, Mg), cation exchange capacity (CEC), base saturation, total N, available and exchangeable K, slope, temperature, and rainfall. Data analysis was carried out by matching techniques, namely matching land characteristics with the growing conditions of tobacco plants to get some suitable land suitability classes for tobacco plants. The results of the analysis showed that the area of ​​land currently planted with tobacco reaches about 12,155.06 hectares, with a suitable class (S2) reaching 897.82 hectares, marginal (S3) reaching 1,614.44 hectares, and not suitable (N) reaching 9,642.79 hectares. Land that has the potential to grow tobacco is S2 (quite suitable) and S3 (marginal).

Abstract

The community in Central Bangka Regency carried out an increase in illegal mining in 2021, which could potentially threaten the loss of strategic natural resources. Rocking table miners in Central Bangka Regency produce zircon sand, tin sand, monazite, ilmenite, and tailings, which are potential natural resources containing rare earth metal elements. This research aims to analyze the radioactive content of the minerals zircon sand, tin sand, monazite, ilmenite, and tailings as a threat to human health. The research showed that monazite samples from all villages still had a lot of rare earth metals in them, like yttrium (Y), lanthanum (La), cerium (Ce), samarium (Sm), neodymium (Nd), and gadolinium (Gd). The test results showed that monazite had the highest average concentrations of Rare Earth Elements (REEs), with values of 10.27±3% for La, 12.15±3% for Ce, 24.40±3% for Sm, 7.37±3% for Nd, and 0.69±3% for Gd. For tin samples, the average (Ce) was 2.79±3%, zircon samples had an average (Ce) of 4.33±3%, and (Nd) 1.04±3%. In the ilmenite samples, the average value (Y) was 6.64 ± 3%. Monazite has the most rare earth metal elements, but it has a very low selling price. Monazite plays a crucial role in safeguarding and preventing the loss of strategic natural resources and health threats. It provides policy advice to related institutions through various roles and functions, including investigation, early prevention, and forecasting of these threats.

Abstract

Farmers began to implement organic systems when the quality of rice fields decreased. Indonesia has several active volcanoes so that the agricultural land was formed by generally Entisols. Several natural and synthetic soil conditioners were starting to be used to decompose the litter and increase the availability of Entisol nutrients. The research aimed to study the effect of providing biological soil amendments on the chemical properties of Entisols. The demonstration plots scale research were used a completely randomized design with a combination of treatments: (P1) Flooded dolomite control, (P2) Non-flooded dolomite control, (P3) Flooded bio soil-neutralizer, and (P4) Non-flooded bio soil-neutralizer. Parameters of soil chemical properties observed were pH, C-organic (%), N-total (%), P2O5-total (%), K2O-total (%), CEC (c mol + kg-1), total bacteria (CFU mL-1), and total fungi (spores g-1). The chemical properties of Entisols before treatment showed slightly acidic pH, low C-organic, low N-total, low K-total, low P-total, and very high CEC. After applying the soil neutralizer, there were an increase in chemical properties including pH becoming alkaline and neutral, medium C-organic, standards to moderat NPK-total, and high CEC. Flooding treatment did not increase the chemical properties of the Entisols.

Abstract

Maize is one of the most important food commodities after rice and is widely cultivated because it has a high protein value. The purpose of this study was to determine the effectiveness of the coating material on the growth and yield of maize under saline stress. This research was conducted in the Agroecotechnology greenhouse of the Faculty of Agriculture, University of Trunojoyo Madura from August 2022 to January 2023. This study used a factorial Completely Randomized Design (CRD) with 10 treatment combinations and 3 replications with a factor of one coating material (P) and a factor of two salinity (K). The coating material factor consisted of 5 treatments namely control (P0), bentonite (P1), biochar (P2), light coal (P3), and biochar compost (P4), the saline stress factor consisted of 2 treatments namely control (K0) and saline (K1). The results showed that the application of coating material to saline stress had a significant effect on all growth parameters. The interaction between treatments only had a significant effect on plant height at 1 MST, leaf area at 6 MST, and 100 seed weight. Treatment (P2K1) with biochar and saline showed the best results on all growth and yield parameters of maize. Saline stress reduced the percentage of growth and yield of maize by about 50%.

Abstract

Critical land is a condition of land that is no longer able to carry out its functions properly because it has experienced physical, chemical, and biological damage. One area that has the potential to experience critical land problems is the Cikapundung Sub-watershed, West Java. This research aims to identify the existence of critical land in the Cikapundung Sub-watershed area by integrating the Geographic Information System, Sentinel-2 Imagery, and DEMNAS as well as mapping the distribution of land criticality levels in the Cikapundung Sub-watershed at a detailed scale (1:25,000). The research was carried out from May to August 2023. The research was carried out using spatial analysis methods by overlaying thematic maps of each critical land parameter consisting of maps of land cover, erosion, and slope. The results of overlaying all critical land parameter maps were then analyzed using a scoring method to classify the level of land criticality and create a critical land distribution map in the Cikapundung Sub-watershed area. The results of identifying critical land in the Cikapundung Sub-watershed area produced five classes of land criticality, namely uncritical, potentially critical, rather critical, critical, and very critical. The identification results show that there are 4210.94 ha (13.83%) of land identified as critical land in the Cikapundung Sub-watershed area. The results of mapping the level of land criticality in the Cikapundung Sub-watershed show that the Cikapundung Sub-watershed area which is included in the forest area is dominated by the moderately critical land criticality class, while the Cikapundung Sub-watershed area which is outside the forest area is dominated by the uncritical land criticality class.

Abstract

Changes in rice fields are an important phenomenon that affects the sustainability of agriculture and the environment. This study aims to analyze the pattern of changes in rice fields in Makroman Village, using a Geographic Information System (GIS) approach. The method used is spatial analysis which involves such as spatial data creation, spatial data conversion, spatial data clustering, and mathematical calculation of spatial data. The spatial data used in this study include Ikonos Satellite Images of Makroman Village in 2011 and UAV Aerial Photos of Makroman Village in 2019. The results showed that the area of rice fields in Makroman Village increased from 96.196 ha to 129.343 ha in 2011-2019. Spatially, the increase occurred due to the presence of new rice fields and existing rice fields that did not decrease in number. Shrubs become land uses that have the potential to be converted in rice field extensification activities. GIS application is a method that can be used to answer the problems in this study to the level of detail, but some things that need to be considered in the application of this method are the quality of spatial data, especially remote sensing data used.
