Abstract

Makassar City as the core city in the Mamminasata National Strategic Area (KSN) has continued to experience population growth since its establishment in 2011. This increase has triggered an increase in demand for land for settlements and other built-up land. Due to the limited availability of land in the city center, there is a phenomenon of land use change in suburban areas. The purpose of this study is to analyze land use changes in Makassar city in the period 2011-2019 and analyze the factors driving changes in land use. The method used is visual interpretation of satellite imagery to obtain land use classes, overlay method to determine land use change and logistic regression method to determine the driving factors of land use change. The results of this study indicate that only three types of land use have increased in area, namely settlements as well as the largest with 29% built-up land by 16% and open land by 5%. While the land uses that experienced a decrease in area from the largest to the smallest respectively were rice fields 18%, ponds 13%, mixed gardens 11%, water bodies 4%, bushes 3%, fields 1%, forests 0.4% and garden 0.1%.

Abstract

One of the main factors that play an essential role in controlling CH4 flux in wetlands is water management through the formation of aerobic and anaerobic soil conditions. Rice plants act as an intermediary medium for the CH4 flux release from the soil to the atmosphere through aerenchyma and trigger CH4 production. Therefore, this study had designed to study the effect of inundation and rice planting on CH4 emissions and the chemical properties of acid sulfate soil. The study had arranged by a randomized block design with two factors, i.e., inundation (not flooded/ponding water layer of 0.5 cm and flooded/ ponding water layer of 5 cm) and rice planting (not planted and planted with rice). The CH4 flux in the flooded treatment was greater than that of the not flooded. Consumption of CH4 occurs in a not flooded condition which had indicated by a negative flux value. Rice cultivation triggered a large CH4 flux. Soil pH and soluble Fe were higher in flooded conditions, while soil Eh had lower.

Abstract

One of the efforts to optimize the growth and production of corn is by potential mapping areas for its development. Minerals are the main elements that have an important role in soil formation and determine the physical and chemical properties of the soil. Minerals are one of the essential indicators related to soil weathering, so the presence or absence of minerals in the soil can indicate how soil formation occurs, especially soil fertility on the land. Jeneponto is one of the corn-producing districts in South Sulawesi, so it is imperative to map its soil fertility based on soil mineral content to be sustainable. The research method used purposive sampling on cornfields in Jeneponto Regency. Soil mineral analysis was carried out using a thin section method, while the analysis of the physical and chemical properties of the soil, including pH, C-organic, and soil texture, followed the BPT procedure; the map was generated using the weighting method and processed by kriging. The results showed that the pH value of the soil was in the slightly acidic to neutral range; C-organic soil had low status in the eastern area and moderate status in the western area of ​​the study site. The soil texture is dominated by clay, silty clay, and silty clay loam. The dominant easily weathered minerals are calcite, pyroxene, and hornblende. Soil fertility status based on nutrient-carrying minerals is in the moderate to the good range with a value of 55-75%. The potential for developing corn plants with priority status is in the Districts of West Bangkala and Bangkala. The second priority is in the Districts of Tamalatea, Batang, Kelara, Rumbia, and parts of Bontoramba, Tarowang, and Arungkeke

Abstract

Cocoa is one of the plantation commodities that has an important role in economic activities in Indonesia. Cocoa can also be used as an alternative source of biohydrogen energy and is very beneficial for health such as reducing the risk of heart attack and stroke, reducing symptoms of depression, lowering blood pressure, maintaining healthy teeth and bones and protecting the body from cancer. The method used in this research is the SPKL application (version 2.0). The results obtained from this study are S3 (marginally appropriate) at the observation points of soil profiles 1 and 4, while the land suitability class N (not suitable) is found in profiles 2, 3 and 5. Limiting factors such as annual temperature, slope, soil depth and coarse fragments, is a limiting factor that is difficult to repair, while soil chemical properties such as K2O can be overcome by fertilization.

Abstract

Abstract Fulfilment of nutrients in the land must be cultivated by increasing the physical and biological properties of the soil so that the presence of nutrients in the ground will be more maintained. The application of technology often used in land use efforts is mostly only focused on chemical fertilization activities. One alternative to reduce the use of chemical fertilizers is to use liquid organic fertilizer (POC) in thitonia and calotropis plant extracts and cow urine. This study aims to obtain a combination of plant extracts that can increase the growth and yield of maize plants and the best blend of biourin and plant extracts in suppressing pests and diseases in maize. The research was carried out on the land of the Faculty of Agriculture, Hasanuddin University (Eksfarm), Makassar City, South Sulawesi, from September to December 2019. The research was arranged using a split-plot design with the first factor as the main plot. The application consisted of 4 levels namely without spraying (K), a combination of bio urine, tithonia extract, calotropis extract, pineapple MOL (B1), bio urine, tithonia extract, calotropis extract (B2) and bio urine (B3) with each application dose of 40 ml/1 liter of water. The second factor as a sub-plot was the spraying interval at the age of 14 DAS which consisted of 3 levels, namely without application, once a week, once in two weeks. The results showed that the application of biourin could increase the growth rate and yield of corn plants. The combination of biourin with plant extracts had a significant effect on the level of pest attack that attacked the leaves and cobs of corn plants and the best interaction between the intervals of application of biourin in increasing the productivity of spraying plants per two weeks.     Keywords: Biourine, Spodoptera litura, Tithonia, Calotropis, Pest attack rate

Abstract

As a natural resources that must be maintained for its sustainability, land with all its functions and roles has an essential position in the ecosystem. As a growing medium for producing biomass, soil has the potential to experience quality degradation due to uncontrolled human activities, especially the production of biomass itself. The first step in overcoming soil damage is to carry out an inventory of the potential soil damage in an area. Inventory can be done by mapping spatially, especially on the potential factors of soil damage. The unavailability of information on potential soil damage, both in terms of area and distribution, is an obstacle in monitoring and controlling soil damage in various areas, including Polewali Mandar District. The purpose of this study was to map the distribution and extent of potential soil damage in Polewali Mandar District. This research was carried out by referring to the technical guidelines for compiling soil damage status maps for biomass production. This map is based on the main thematic maps and other supporting data and information. The potential for soil damage was analyzed using two approaches, namely the superimpose/overlay method or overlapping thematic maps and the scoring method for factors considered to have an effect on soil damage. Based on the results of the weighting analysis of all potential soil damage variables, information is obtained that the research area has 3 classes of potential soil damage. Potential damage II (PR II) with a low class area of ​​49,288.1 Ha or about 23% of the research area. The potential for damage III (PR III) with moderate class is 147,553.7 ha or about 70.7% of the research area. The potential for damage IV (PR IV) with high class area is 613.6 Ha or about 0.3% of the research area.

Abstract

Management of peat soil for pineapple cultivation in Kualu Pineapple Village is still very traditional. In planting not using spacing, fertilization only uses fertilizers containing N, namely urea. In addition, there are differences in principles in managing peat, namely that there are farmers who add ameliorant ingredients and some do not. The purpose of this study was to determine the chemical properties of the soil, and nutrient uptake of pineapple plants in Kualu Nenas Village where the soil was given dolomite lime ameliorant and without ameliorant. This research method uses qualitative (survey) and quantitative (laboratory analysis) methods. A sampling of plants whose soil was given dolomite lime ameliorant and soil without ameliorant was carried out by purposive sampling technique. The research data were analyzed by a T-test to determine the difference between the chemical properties and nutrient uptake of pineapple plants. The T-test was analyzed using the SAS program (SAS User Manual Version 9, 2004). The results of this study were that the soil PH, P-available, K-dd, Ca-dd, Mg-dd, CEC, and base saturation content in pineapple plantations where the soil was treated with dolomite lime ameliorant had a significantly higher value based on the T-test compared to pineapple plantations with no ameliorant. Nutrient uptake of N, P, K, Ca, and Mg in pineapple leaves was not significantly different between plants whose soil was treated with dolomite lime ameliorant and those without ameliorant.
