The establishment of Sawangan district, Depok municipality as an urban service sub-centres (SPK) has encouraged urbanization to the zoning. The population increase and the demand for land for the conversion is a consequence. Land-use change has become an environmental issue in the SPK Sawangan, specifically soil degradation. The objectives of this study were to assess the condition of soil degradation based on the criteria for evaluating the parameters of soil physical properties in the SPK Sawangan. Observation method on the soil physical properties were carried out at five sample plots. The assessment technique referred to standard assessment criteria for controlling soil degradation for biomass production. The results showed that the parameters that affect soil degradation are acidity (T1,T3, T5), soil bulk density (T4), permeability: fast (T2,T3) and slow (T4). Overall conclusions, soil degradation at the SPK Sawangan zoning shows the condition of low damage. The policy implications are that stakeholders need to carry out technical management of land, especially on land that has the limiting parameter value that exceeds or is outside the critical threshold value.

Prominent problems in suboptimal land are often only related to the chemical and physical properties of the soil such as low soil pH, available nutrients and the ability of the soil to supply available water. Assessment of soil biological characteristics is needed to look at soil problems on dry land more comprehensively. The purpose of this study was to conduct a preliminary study of the variability of soil biological characteristics in suboptimal dry land. This study was carried out with a field survey accompanied by soil sampling using a composite method in 24 land locations which are the centers of development of the Department of Agriculture commodity development in five districts in Central Java Province that were randomly selected. In addition to soil organic matter, soil biological characteristic studied was the total number of soil microorganisms. The results of the study on both potato and sweet potato commodity lands showed there were intervals of the number of soil microorganisms, namely 1.83 x 105 - 1.63 x 106 CFU g-1 of soil and 3.90 x 105 - 1.10 x 106 CFU g-1 of soil. While the interval of soil respiration value is 4.80 - 10.97 mg C-CO2 kg-1 of soil day-1 for potato commodity land and 5.31 - 10.80 mg C-CO2 kg-1 of soil day-1 for sweet potato land. There was no strong correlation between the number of soil microorganisms and soil respiration, which was indicated by a correlation value of 0.29. The biological characteristics of the soil varied greatly, and they did not affect the type of commodity or location.

Lapindo Mudflow in Sidoarjo in 2006 brought heavy metals cadmium (Cd) that polluted the soil and environment around the affected area. Phytoremediation using water spinach (Ipomea reptans) is one of the alternatives to decrease the heavy metal pollution on Lapindo mud. The organic materials (compost and biochar) can also be used to reduce the contamination of heavy metals in soils. The aim of this study was to obtain the best composition of organic matter and biochar to support phytoremediation using water spinach plant in the cadmium-polluted soil. The study was conducted in a greenhouse with eight treatments consisted of four levels of organic matter application. The parameters measured were plant height, number of leaves, pH, CD content, and uptake of Cd. The results showed that there was a significant effect on the addition of compost and biochar on plant growth, Cd content, and Cd uptake. Results of the study showed that the addition of compost gave better results than that of biochar. The best treatment was on K7 (contaminated soil : compost : biochar; 1:1:1) for all parameters observed. Compared to the K0 (control) treatment, height of the plant increased up to 24%, the number of leaves increased up to 100%, the Cd content in the roots and shoots increased up to 44% and 95%, the content of the Cd in the planting media after the planting period decreased by 61%.

Meru Betiri National Park (TNMB) is a natural conservation area related to land use that impact on the environment. Land-use suitability with land capability is essential so that the impact of the geological environment that can occur can be reduced and controlled. The research aims to determine the aspects of environmental geology and zoning land capability for governance of TNMB. Geological aspects of the environmental order that support this research are morphology (slope), lithology, hydrogeology (river density), and land cover. Each aspect is a parameter in the Analytical Hierarchy Process (AHP) evaluation method. The weight of each parameter of the AHP evaluation result is 26% for slope, 19% for lithology, 11% for river density, and 44% for land cover. The result of overlay parameters yields a score of each zoning and is classified into 4 (four) zoning land capabilities for governance of TNMB. The land use zone for governance of TNMB is divided into high capability zones, medium capability, low capability, and very low capability. High and medium capability zones can be used as conservation of TNMB primary forests.

As the population increases, the need for detergent will increase. This study aimed to determine the value of TDS in detergent solution at different concentrations and detention times. This study was an experimental study using a randomized block design with three treatment factors. The treatments included phytoremediation (presence or absence of plants), detergent concentrations used were 10, 50, and 75 ppm, and detention times were 7 and 14 days, each with three replications. The tool used was the TDS Meter. The data obtained in the form of TDS values were further analyzed descriptively and presented in the form of tables, graphs and descriptive analysis. The results showed that the TDS values fluctuated every day. The lowest average TDS value was found in phytoremediation treatment with a concentration of 10 ppm with a detention time of 7 days which was 174 mg L-1, while the highest average TDS value was found in phytoremediation treatment with a concentration of 75 ppm with a detention time of 14 mg of 237 mg L-1. The higher the concentration of detergent and the longer the detention time in the phytoremediation treatment, the higher the average TDS value.

Each land use has a different vegetation density and the litter input as a source of soil organic matter. Vegetation density index can be analyzed based on the NDVI equation using the GIS approach. This study aims to determine the effect of different land uses and NDVI on soil organic matter content and the mapping of soil organic matter content. This research was conducted from AprilÂ to August 2019 in Turen District, Malang Regency. The survey method used for collecting data in the field (36 observation points) based on differences in landform, relief, slope, land use (irrigated and rainfed rice fields), and vegetation density index classes (low, medium, high). Soil samples were taken at 0-20 cm depth and analyzed for soil organic matter content. Data interpolation using IDW was used for mapping soil organic matter. The results showed that there was a very significant effect between differences in land use and NDVI class on the content of soil organic matter (p <0.001). NDVI value gives an effect of 81.5% on soil organic matter content. The distribution of soil organic matter content is classified into 5 classes, which are very low, low, moderate, high and very high.
