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%.

Soil contains many elements, both macro, micro and metal. Metal elements are generally non-essential. Cobalt (Co) is one of the metallic elements but required in very small amounts for life. At high concentrations of cobalt can cause poisoning. One way to reduce high levels of cobalt in the soil by performing bioremediation plus ameliorant materials. This study consists of two stages. The first stage is the pot scale research with factorial design. The first factor is the bioremediator dose, namely : B0 : Without bioremediator (control), B1 : Bioremediator 20 kg ha-1, B2 : Bioremediator 50 kg ha-1 and the second factor is the application of ameliorant materials, namely: A0 : No ameliorant (control), A1: Biochar + compost (1: 5), A2 : Biochar + compost (2: 5), A3 : Activated charcoal + compost (1 : 5), A4 : Activated charcoal + compost (2 : 5). The second stage is the four best results from the first stage applied in situ on the lysimeter. The results showed that the treatment of bioremediator with a dose of 20 kg ha-1 and activated charcoal + compost (w: w = 2: 5) was able to reduce Co levels in the soil by 76%. The lowest Co level in rice that is equal to 3.06 mg kg-1 was obtained from the treatment of 50 kg bioremediator ha-1 plus active charcoal + compost ameliorant (1: 5).Â

Biofertilizer applications are needed to improve soil quality such as soil productivity and increasing the efficiency of the fertilization. Availability of nutrients in the soil is affected by microbes found in the soil. Soil microbes reproduce themselves and active in supplying nutrients to plants by releasing nutrients that are bound to be available to plants. The aim of this research was to observe and analyze the effect of biofertilizer on sugarcane growth and its effect on the population of potassium solubilizing bacteria. Results showed that The application of basic fertilizer combined with biofertilizer has a significant effect on the growth of sugarcane both in plant height and diameter of the stem. In the parameters of plant height, the best treatment was A5 which was a combination of anorganic fertilizer + 200% biofertilizer same as the other plant growth parameter which was stem diameter. Then on the production parameters, fresh plant weight and root weight, best treatment was A5. As for the parameters of potassium solubilizing bacteria, the best treatment that increased population was treatment A4 which was basic fertilizer combined with 150% biofertilizers. In total soil bacteria, the various application doses of biofertilizers did not have a significant effect. However, there was an increase of 0,49% in treatment A5 (basic fertilizer+200% biological fertilizer) compared to control (A1). The application of biofertilizer also did not have a significant effect on the parameters of organic matter and soil water content

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.

South Sumatra Province has the potential of agricultural land, especially rice food, so it is necessary to manage agricultural land optimally to support the availability in meeting food needs. This research was focused on the carrying capacity of food that aimed to determine the carrying capacity of land/food based on supply and demand of land/food so that it can be known that the carrying capacity of regional food is sufficient or not in meeting food needs. This research method used a quantitative descriptive. The results showed the South Sumatra Province's food carrying capacity based on the incoming category/surplus category with a value of 3.32 or 2,167,003.04 tons of rice, but still included in the budget and deficit areas, would be adjusted to those that entered a large surplus. While the regions that indicated the lowest deficit level at the score limit of 0.93-1.89 were five regencies/cities, while the deficit at the score limit was 0.08-0.95 as many as four regencies/cities. Regions that are indicated deficit become the main priority to be supported by regions indicated by large surpluses.
