Abstract

Title : The Uptake and Tolerance of Azolla to Chromium on Vertisols and Entisols at Various Water Levels. This research aims to study the effect of water level, soil kind, chromium concentration (Cr), and their interactions on uptake and tolerance of azolla to Cr. The research was done in March to May 2009 in the green house of Faculty of Agriculture, Sebelas Maret University, Surakarta. The research used completely randomized design (CRD) factorial with three treatment factors, they were: soil kind (Vertisols of Jatikuwung and Entisols Colomadu, Karanganyar), water levels (0; 2; and 7 cm) and Cr concentrations (0; 5; 10; 15; and 20 ppm). There were 191 g of Vertisols and 200 g of Entisols pass to 2 mm sieve put into plastic pot and watering at various levels according to the treatments. A gram of fresh azolla was spread on each pot and incubated for three weeks. Each treatment combinations were replicated three times. Sampling was taken at 1, 2, and 3 weeks after planting for azolla biomass, Cr uptake of azolla, available Cr, and Cr toxicities symptoms of azolla. The data analyzed statistically by Kruskal Wallis test at 95% level significant, followed with Mood Median test. The result shows that soil kind has no significant effect, while water level, Cr concentration, and treatment interaction contribute highly significant influence on uptake and tolerance of azolla to Cr. The highest uptake of Cr at the Vertisols was taken at 7 cm water level and 15 ppm Cr concentration, while at the Entisols was in 2 cm of water level and 15 ppm Cr concentration. Azolla most tolerance to Cr at treatment combination of 2 cm water level and 10 ppm Cr concentration in Vertisols, and at 2 cm water level and 5 ppm Cr concentration at Entisols.

Abstract

Ratoon system is a method of rice cultivation that produces new tillers after the mother plant is harvested and is continued by maintaining and caring for the shoots of the mother plant. In Indonesia, SALIBU and SINGGANG, which are types of rice ratooning, have been developed for Sumatra and Java regions, respectively. SALIBU is an innovation or a modification of the rice ratoon system that focuses on maintaining the time of fertigation and cutting of plant height. SINGGANG, on the other hand, is a rice ratoon system in which the management of fertigation and cutting is not considered. Both systems have not yet been implemented outside their places of origin. This study aims to compare the conventional and modified rice ratoon systems considering parameters such as soil properties, nutrient uptake, and the growth and yield of rice. The effects of rice ratoon systems (SALIBU and SINGGANG,), soil types (Inceptisols, Alfisols, and Vertisols), and cultivars (Pandan Wangi and Mekongga) were evaluated. All treatments were evaluated in a completely randomized design with three replicates in the net house. The results showed that the soil porosity in SINGGANG (48.89%) and SALIBU (46.78%) systems was higher than the conventional system (43.17%) in the Inceptisol soil and Pandan Wangi cultivars. Moreover, SINGGANG had a positive effect on the physical properties of soil (porosity and permeability); whereas, SALIBU had a positive effect on the chemical properties of soil (pH and organic carbon). In contrast, the agronomic parameters showed that the weights of dry matter and dry yield for SINGGANG were 44.96 and 23.09 g per plant clump, respectively, while those for SALIBU were 55.54 and 25.74 g per plant clump, respectively. These were lower than the conventional system (63.18 and 31.21 g per plant clump, respectively). Thus, we concluded that the SINGGANG and SALIBU ratoon systems had a positive impact on soil properties, but both systems could not promote higher rice production than the mother plant in all soil types and cultivars.

Abstract

The Standardized Precipitation Index (SPI) and the Standardized Precipitation Evapotranspiration Index (SPEI) are used to monitor and identify different types of drought, including meteorological, hydrological, and agricultural droughts. This study evaluates the accuracy of estimating soil moisture levels using the two indexes. The analysis correlated the SPI and the SPEI over three years (November 2016–October 2019) using Rstudio, with average monthly soil moisture taken using a Soil Moisture Sensor; 3-, 6- and 12-months SPI and SPEI showed a positive correlation for soil moisture (Sig <0.05), whereas 1-month SPI and SPEI results did not.  A regression test was used to get an equation model for estimating soil moisture content. The correlation for soil moisture between the 1-month SPI and SPEI results was insignificant (p-value >0.05). In contrast, the 3-, 6-, and 12-months indexes were significant (p-value <0.05). Estimating soil moisture content using the SPEI (50–59.09%) had a higher accuracy value than the SPI (36.36%), which indicates the SPEI can more reliably predict soil moisture.

Abstract

Indonesia is the world’s third largest rice producer, with most rice being cultivated (estimated 3.1 million ha) in Central Java. However, one of the environmental challenges in producing rice is greenhouse gas (GHG) emissions from rice fields. Therefore, understanding the GHG emissions (methane and nitrous oxide) from the rice farming system is important for better management practices. The objective of this study is to estimate the GHG emissions supported by a satellite database, namely, the DeNitrification DeComposition (DNDC) model, at three regencies at Central Java, Indonesia, Cilacap, Karanganyar, and Pati, as well as the factors determining the emissions. The DNDC model was obtained from https://www.dndc.sr.unh.edu, which consists of three main submodels that worked together in simulating N2O and N2 emissions: (1) the soil-climate/thermal-hydraulic flux submodel, (2) the decomposition submodel, and (3) the denitrification submodel. The results showed that the N2O emissions from rice farming in Karanganyar, Cilacap, and Pati were 19.0, 18.8, and 12.8 kg N ha−1 yr−1, respectively, while they were 213.7, 270.6, and 360.6 kg C ha−1 yr−1 for CH4 emissions, respectively. Consecutive dry or high precipitation, which resulted in cumulative depleted or elevated soil moisture, respectively, along with warmer temperature likely promoted higher methane and nitrous oxide. Experimental fields for validating the model in accordance with various agricultural practices are suggested for further study. Overall, the DNDC model has successfully estimated the CH4 and N2O emissions in Central Java when incorporated with various secondary climatic and land management big data resources.

Abstract

Evapotranspiration data are considered important to determine volume and schedule of the irrigation. The purpose of this study is to determine the actual evapotranspiration model based on the volume of the irrigation to obtain an accurate evapotranspiration value on Alfisols with maize plantation. This research is conducted in the experimental field Jumantono subdistrict, Karanganyar regency by the experiment of the maize (Zea mays) on Alfisols. The evapotranspiration model uses the soil correction factor (x) and the irrigation volume (% ETc). The soil correction factor (X) is calculated by linear regression on actual evapotranspiration (ETa) with crop evapotranspiration (ETc). ETc using reference evapotranspiration (ETo) using the Penman-Monteith model. The results showed that ETa was smaller than ETc in all treatments. The models that can be produced in this study are 3 models. All models applied to produce a determination coefficient > 90%, which all models have a positive relationship. The best actual evapotranspiration model was in total model uses ETa = {0.0403 + (0.0085 × Irrigation volume)} × ETc, for daily estimation and total one planting estimation;  weekly estimation using the weekly model using ETa = {0.4428 + (0.0054 ×Irrigation volume)}× ETc. The errors of both models are ± 1%.

Abstract

Himawari 8 satellite image, which was launched in October 2014 and began the operational in July 2015, serves to identify and track the phenomenon of rapid changes in weather. The purpose of this research was to determine the model of local air and soil temperatures using Himawari 8 satellite image. Local air and soil temperatures information was collected from the Climatology Station of Semarang district, Central Java, Indonesia. Interpretation of the Himawari 8 satellite image was performed, as well as the statistical tests of correlation and regression, according to the sun's pseudo motion. Pair correlation and regression analysis on satellite image with air temperature; and air temperature with soil temperature (bare and grass). The results showed the satellite imagery of Himawari 8 could predict the air and soil temperatures, especially bare soil. In specific, the accuracies were higher on soil temperature at 0 (surface) and 5 cm depth. But each period produced vary accuracy, due to many weather elements had may affect the air and soil temperatures.

Abstract

Soil organic matter (SOM) is one of the important parameters in agriculture management, thus estimating its distribution on the land will be essential. Remote sensing can be utilized to map the SOM distribution in the large-scale area. The objective of this research was to determine the estimation of SOM distribution on the paddy field in Sukoharjo Regency, Indonesia using Landsat 8 OLI imagery. The sampling points were determined by purposive sampling based on an overlay of land use classification map of paddy field, NDSI (Normalized Difference Soil Index) map, and soil type map. The analysis method was used simple linear regression (SLR) and multiple linear regression (MLR) between SOM content and a digital number of Landsat 8 OLI imagery. The SLR analysis resulted that all band except band 1 and 5 of Landsat 8 OLI Imagery have the capability to estimating SOM. The MLR model based on best subset analysis resulted in the combination of bands 3, 4, 6, and 7 was the best model for estimating SOM distribution (R2=0.399).  The MLR model was used to create SOM distribution map on paddy field in Sukoharjo Regency and resulted in the SOM range of the area is distributed from very low (<1%) to moderate (2.1–4.2%) with the largest area was on low level (1–2%) about 11,028 ha. The result indicates that Landsat 8 OLI Imagery could be used for mapping the SOM distribution.
