Abstract

Land suitability is one method used to assess the suitability of a commodity to be cultivated sustainably on land. This research aimed to highlight the issue of agricultural land for maize in Kulah Hilir District, Labuhan Batu Regency, North Sumatra. The method used in this research is the matching evaluation method (weight factor match). The data used in this research is secondary data sourced from research data in the form of rice agricultural land suitability data with the title Evaluation of Land Suitability for Rice (Oryza sativa L.) in Kualuh Hilir District, Labuhanbatu Regency. North, North Sumatra. This research showed that the land suitability class of corn in Kualuh Hilir District, North Labuhanbatu Regency, North Sumatra, using the weight factor matching method, is in class S2, "quite suitable" for planting corn plants. There are two limiting factors in land adjustment from rice plant data for corn plants; namely, the limiting factor for nutrient retention (nr) is only (base saturation (%)) and pH H2O with a land suitability level of "marginal suitability" S3 but improvements can be made to increase the class. The suitability of the land with the addition of organic materials and lime ameliorant materials with low to medium input can increase the potential suitability class of the land to S2.

Abstract

The level of land suitability for lowland rice can be determined by conducting a land suitability evaluation. Information related to land suitability classes can be used as a reference in taking appropriate action in managing rice fields so that production targets can be achieved. The aim of this research is to determine the actual land suitability class for lowland rice crops in Suka Maju Village, Malind District, Merauke Regency. This research used a survey method and soil sampling was carried out on two types of land, namely paddy fields and grasslands. Data collection was carried out by direct observation, laboratory analysis and data analysis. The data analysis technique to determine the subclass of land suitability is to match the growing requirements for lowland rice plants with the quality and characteristics of the land according to the Technical Guidelines for Land Evaluation for Agricultural Commodities, 2011 Revised Edition. The results of the research show that the land suitability class for lowland rice plants is on both types of land. (rice fields and grasslands) are classified as marginal suitability class (S3) with the limiting factors being rooting media (rc), nutrient retention (nr) and available nutrients (na). Basically, the limiting factors in this research can be improved by liming, fertilizing and adding organic materials.

Abstract

With increasing concerns regarding water resource management and environmental sustainability, understanding land use change and the hydrological health of watersheds is critical for informed decision-making. This study aimed to explore the effect of land use changes on hydrological health resilience in the Rejoso watershed, East Java, using remote sensing techniques and geographic information system tools to characterize the various land cover types. Landsat ETM 7+ satellite imagery was used to describe land cover classes. Hydrological health indicators such as water transmission, water availability during the dry season, and peak rainfall buffer events were systematically analyzed in relation to land cover change conditions. Regression statistical methods were used to measure the impact of land cover changes on hydrological parameters. The study results showed that the area of forest land in the Rejoso watershed tended to increase from 2011 to 2021; on the other hand, the area of agroforestry land tended to decrease along with the increase in upland land. In general, the hydrological health of the Rejoso watershed is decreasing from year to year. The increase in forest area, agroforestry, settlements, and ponds provides a positive response to the hydrological health of the watershed. On the other hand, the increase in moorland and rice fields has a negative impact on the hydrological health of the watershed.

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

The occurrence of flood disasters is an annual unavoidable event in the Mejobo District, Kudus Regency. This study aims to map the vulnerable areas to floods in the Mejobo District using spatial modelling. The parameters used to determine the vulnerability areas include soil type, elevation, population density, river buffer, rainfall, and land use. The research location is situated in the Mejobo District. The research method employed is the models and multicriteria decision-making (MCDM) techniques, with the assistance of ArcGIS software for data processing and analysis. The research findings yield a final map depicting flood vulnerability, which indicates the distribution of flood-prone areas. Areas with a high level of flood vulnerability are dispersed across agricultural fields and areas adjacent to rivers, covering an area of 1,770 hectares. Meanwhile, areas with a moderate level of vulnerability are predominantly distributed in residential areas, covering an area of 1,907 hectares.
