Abstract

Information on land quality as the basis for land management in maize cultivation at the site level is very important, but generally not always available. Study aimed to determine the distribution pattern of nutrient retention and availability in Pilolaheya Village, Bone Bolango Regency. This study used soil survey and deskwork methods to analyze data of nutrient retention (organic C-OC, pH, base saturation-BS, cation exchange capacity-CEC), total N, P2O5, and K2O for nutrient availability. The result shows that the distribution pattern of nutrient retention in corn topose sequences for soil pH on the lower slopes, base saturation on the lower and middle slopes tended to increase with soil depth, while soil pH on the upper slopes, OC and BS on the upper slopes tended to be the opposite., while the soil pH on the middle slope, OC on the lower and middle slopes, and the CEC of all slopes tended to be irregular with the depth of the soil. The distribution pattern of nutrient availability for Total N on the lower and middle slopes, and P2O5 on all slopes tends to be irregular with soil depth, while the total N on the upper slope tends to decrease with soil depth, while the distribution pattern of K2O on the middle and upper slopes tends to be the same, but inversely proportional to the distribution pattern on the downslope

Abstract

Rice (Oryza sativa) is one of the food commodities that have an important role that is used as a staple food for most of the world's population, especially in Indonesia. Plant Growth Promoting Rhizobacteria (PGPR) is one of the bioorganic fertilizer that can be used to stimulate plant growth. The purpose of this study was to examine the effectiveness of PGPR to support seed germination. The first step is to make PGRP from bamboo roots with 3 methods. PGPR was then tested to see the germination of rice seeds through the rolled paper test method. The provision of PGPR has little effect on the length of the root length of rice sprouts. The root length of the PGPR treatment is 10.68 cm while the control is 10.45 cm. This shows that the PGPR treatment has a fairly good impact on the development of sprouted rice roots. PGPR treatment has an effect on the wet and dry weight of roots and shoots of rice sprouts. The average wet and dry weight of the PGPR treatment were higher than the control treatment. PGPR is recommended to be given to obtain rice yields to obtain better quality and quantity of rice plants.

Abstract

Landslides are common problems in watershed management due to their social and economic impacts. Landslide susceptibility mapping is needed to identify areas that need priority in the mitigation program. In landslide susceptibility mapping, the most commonly used geological map is regional map, which is not suited for small to medium-sized areas such as the Kladen watershed, in Rembang, Central Java. This study aims to improve the available geological map with a more detailed lithological unit than regional geological maps, and produce susceptibility maps using geological, geomorphological, and land cover variables. A comparison was performed between the results obtained with the regional geological map and the improved geological map. The logistic regression was selected as it has provided high accuracy for landslide hazard analysis, and does not depend on the subjectivity of the researcher. The results of the landslide susceptibility analysis with regional geological maps show that the lithological factor is statistically insignificant, while in the analysis with a more detailed geological map, it was significant and has higher relevancy than the geomorphology and land cover. The predictive performance test of both models with the area under the curve method shows that the improvement of the geological map increases the performance value from 0,704 to 0,782, producing more reliable landslide susceptibilty map.

Abstract

Water balance calculations can describe water conditions in an area. Climatic conditions and soil characteristics will affect the water balance in an area, including the karst areas which is vulnerable to droughts. This study analyzes the capacity of the soil to store water and calculates the regional water balance. By using the Soil Moisture Equipment Corp at a pressure of 0.33 atm, the field capacity of the soil and a pressure of 15 atm will be known to obtain the permanent wilting point value. The regional water balance was calculated using the Thornthwaite-Mather method. Research conducted in the karst area of ​​Maros Regency shows that the available water pore value with very low criteria so that it affects the available water capacity. The water balance of the karst region shows a surplus in November-June and a deficit in July-October. The total value of surplus is 1296 mm/year and deficit is 370 mm/year.

Abstract

The need for built-up areas in the City of Makassar has continued to increase in recent years due to the rate of population growth. The reduced availability of land in the center of Makassar City causes the demand for built-up areas to shift to suburban areas. In this shift, there is a process of changing the use of non-built-up land into built-up areas. Reduced use of non-built-up land in suburban areas can cause environmental damage. The aims of this study are: (1) to predict changes in land use in Makassar City until 2034, (2) to develop directions for controlling built-up areas. The method used is visual interpretation (digitize onscreen) to obtain land use maps for 2012 and 2022, the Land Change Modeler (LCM) model to predict land use change in 2034 by comparing two land use scenarios, namely Without Scenario (TS) and Restriction Built-up Area (PAT). Scenarios that are able to reduce the rate of development of built-up areas will be chosen as directions for spatial use until 2034. The results of this study show the same pattern of land use change in the two scenarios used, namely only settlements, built-up land and open land that experience an increase in area during the analysis period. However, this scenario differs in terms of the extent of change. In the TS scenario, settlements increase by 706 ha (34%), built-up land by 272 ha (13%) and open land by 61 ha (3%). This increase reduced the area of paddy fields by 425 ha (20%), mixed gardens by 228 ha (11%), ponds by 222 ha (11%), shrubs by 69 ha (3%), forest by 52 ha (3%) and water bodies by 44 ha. (2%). Whereas in scenario 2, the increase in settlement area is only 265 ha (31%), 114 ha (13%) built-up land and 44 ha (5%) open land, so that the decrease in the area of other land uses is also small, namely rice fields 186 ha (22 %), ponds 109 ha (13%), mixed gardens 88 ha (10%), shrubs 21 ha (2%), ponds 12 ha (1%) and forest 7 ha (1%). The PAT scenario proved to be more effective in restraining the rate of development of built areas so that it was chosen as the direction for controlling built areas in Makassar City until 2034.

Abstract

Nutrients are the most important thing in plant growth, where one of the nutrients in the soil is nitrogen, phosphorus, and potassium. Without nutrients in the soil, the growth process in plants will also experience obstacles. This study aims to determine the percentage of NPK nutrient content in the soil and to provide fertilizer recommendations for nutrient-deficient soils in Metun Sajau Village, Bulungan, North Kalimantan. This research method uses a random sampling technique based on randomization rules, namely, there is no limit to the number of soil samples to be selected by using GPS to determine the sampling point and by using a mineral drill to take soil samples at each location. All sampling points have the same probability and are independent of each other. Soil sampling will be carried out by taking the top layer of topsoil with a depth of about 0-30 cm by taking 12 soil sample points. And with the provisions of 0.5-3 Ha / 3 points of soil samples. Then the soil samples that have been taken are composited and then labeled. Soil samples taken from the field will then be analyzed and tested in the University of Borneo Tarakan soil laboratory for analysis. The results showed that the recommended fertilization recommendations were Urea, SP-36, KCL, and 15-10-12 compound fertilizer with doses according to plant age and class suitability conditions on the land.

Abstract

The use of fish pond mud in improving soil quality is generally still not widely used. This study used various doses of pond mud to determine the effect of pond mud doses on the availability of N and Fe-soluble in Ultisol soil planted with mustard greens. The research was conducted in the Greenhouse in April - May 2022 with a Completely Randomized Design (CRD), five doses of fish pond sludge namely at doses of 0; 0.5: 7.5: 10; and 12.5% applied to Ultisol soil. The results showed that applying fish pond sludge significantly affected soil pH, N-NO3-, N-NH4+ and Fe-soluble. Soil pH decreases due to a reaction between water and Fe compounds that bind OH- and release H+. Whereas N-NO3-, N-NH4+, and soluble-Fe significantly increased due to chemical reactions that produced soluble salts which reacted with water. As for the soil parameters, the effect of pond mud decreases soil pH at all doses of addition of mud and increases N-NO3-, N-NH4+, and soluble-Fe Ultisol, with the best doses of M3 (equivalent to 1 kg mud + 9 kg of soil). There is a relationship between the chemical properties of the soil and the fresh weight of the plants, as evidenced by the increase in the wet weight of the mustard plants.
