Abstract

Estimation of Rice Production Using Landsat 8 Satellite in Tabanan District Agricultural sector is currently a very important sector considering that everyhuman being needs food to survive and as a source of energy to carry out dailyactivities. Production estimation that are accurate and timely can provide informationfor planners and decision-makers to formulate appropriate policies when conditionsare inadequate or overstocked. The technology that can be used is remote sensing usingthe Landsat 8 satellite. The greenness level parameters of plants (Vegetation Index)obtained through satellite image analysis can be used to estimate rice production. Theresearch area is located in Tabanan Regency. Estimation of rice production is done bythe equation y = 2.0442e1.8787x, where x is the NDVI value from the Landsat 8 imageand y is the result of rice production. The estimation results using Landsat 8 are oneseason production in tons/ha. The accuracy test is done by paired t-test and correlationanalysis. Paired t-test shows that there are no significant differences between riceproduction estimation from BP3K and rice production estimation using Landsat 8.Correlation analysis results show that there is a linear relationship between statisticalresults and estimation results with R2value 0.9682 with the equation y = 1.0099x -0.0794, where y and x are Landsat 8 estimates in tons/ha and BP3K data respectively,with a Standard Error (SE) of 0.1984.

Abstract

Analysis Of Need For Green Open Space Based On Oxygen Needs Using Remote Sensing Technology In Badung Regency Badung Regency is one of the regencies in Bali Province which has a quite rapid development. Total population of Badung regency in 2018 was 656.90 thousand people with population growth rate of 4.64 % which is the highest growth rate in Bali Province. The objective of this research is (1) to map the percentage of green open space in Badung Regency using Sentinel-2A satellite imagery, (2) to analyze the oxygen needs of Badung regency, and (3) to evaluate the need of green open space in Badung regency based on availability of green open space and the need for oxygen. This study was a descriptive quantitative research who utilize remote sensing technology using the satellite imagery of Sentinel-2A and Gerarkis methods. The methods of sample collection was stratified random sampling with the number of sample is 76. The estimated density of vegetation derived from a comparison between the five indices of vegetation that is NDVI, RVI, DVI, TVI, and SAVI. The result of study shows that the SAVI is the best vegetation index for green open space estimation based on the determination coeffecient (R2) value. The t-test paired confirm as well that there are no significant different between green open space obtaining from estimation using Sentinel-2A satellite imagery and direct measurement on high-scale images. The estimation result of vegetation density indicates that the vast green open space in Badung Regency in 2019 was 22.930,67 ha. The extent of the need of green open space based on oxygen demand by residents, vehicle, and livestock in 2019 is 7.516,34 ha.

Abstract

Estimation of Rice Production Using Sentinel-2a Image in Tabanan Regency Rice is strategical commodities because rice is a primary food in Indonesia. Thus, the estimation of rice production becomes crucial to do before the time of harvest to determine the availability of food. The objectives of this study were (1) developing of estimation equation model using Sentinel-2A imagery, (2) estimating rice field production using Sentinel-2A imagery, and (3) testing the accuracy of rice production estimation results using images Sentinel-2A. The research area is located in Tabanan Regency. Analysis of the research is done by the analysis of the single band and vegetation indices of Sentinel-2A satellite imagery. Estimation model of rice production developed by finding out the relationship between the satellite imagery data and the rice production data. Finally, accuracy test of the rice production estimation model is done using t test and regression analysis. The result of the study shows that the Normalized Difference Vegetation Index (NDVI) has the best relationship with the rice age and then used for the rice production estimation. The equation of rice production estimation is y = 7,7429ln (x) + 11,147, where y is the rice production in ton/ha and x is the value of NDVI of Sentinel-2A imagery in rice age range of 57 to 67 day after transplanting. The results of the accuracy test showed that the model obtained is suitable for estimating rice production with the accuracy level of 84,59% and a standard error of estimated production of ± 0,7463 ton/ha. Based on the research results, it can be concluded that the Sentinel-2A satellite imagery can be used to estimate the rice production with the enough accuracy. The results are expected to be a reference in estimating rice production in Tabanan Regency.

Abstract

ABSTRACT Classification and Mapping of Soil Family Based on Soil Taxonomy System at Penatih Dangin Puri Village, District of East Denpasar. The research at Penatih Dangin Puri Village, aims to classify and mapping the soil at Penatih Dangin Puri Village based on Soil Taxonomy System up to soil family category. This research was using soil survey method at the field to observed soil morphology, soil test at laboratory for the properties of physical, chemical, and clay fraction mineralogy. Soil classification was conducted until soil family category, semi detailed soil mapping with the scale of 1 : 25.000. The result of soil classification showed that the soil at Penatih Dangin Puri Village is classified into the order of Inceptisol and Mollisols, sub-order of Aquepts and Udolls, great group of Epiaquepts and Hapludolls, sub-group of Typic Epiaquepts, Typic Hapludolls, and Aeric Epiaquepts, family of Typic Epiaquepts, very fine, mixed, isohyperthermic; Typic Hapludolls, fine, mixed, isohyperthermic and Aeric Epiaquepts, fine-loamy, mixed, isohyperthermic. Semi detailed soil mapping with the scale of 1: 25.000 at Penatih Dangin Puri Village generates 5 SPT (Soil Mapping Unit), namely: 1) Association of Typic Epiaquepts, very fine, mixed, isohyperthermic with Aeric Epiaquepts, fine-loamy, mixed, isohyperthermic; 2) Typic Epiaquepts, very fine, mixed, isohyperthermic; 3) Typic Hapludolls, fine, mixed, isohyperthermic; 4) Typic Hapludolls, fine, mixed, isohyperthermic; and 5) Typic Hapludolls, fine, mixed, isohyperthermic.

Abstract

The Mapping of Soil Quality Under Mixed Dry Land Farming Using Geography Information System (GIS) at Tegallalang, Gianyar Regency Mapping of soil quality undermixed dry land farming area using GIS was held in Tegallalang, Gianyar Regency on October 2016 – January 2017. This research implementing exploratory method on the purposive land use followed by laboratory soil analysis. Soil samples were randomly taken on each homogeneous land units on the map developed by overlaying slope, soil type, and land use maps. The following soil quality indicators as the minimum data set (MDS) were measured: soil bulk density, porosity, field capacity water content, texture, pH, C-Organic, CEC, base saturation, nutrients (N, P and K), and C-biomass. The values of soil quality were mapping using QGIS 2.18.0 and refer to land management direction. The results showed that the soil quality in the research area considered being good and medium level. The good soil quality present on land units laid down on the wavy slope had different land cover vegetation, different land management systems (fertilizer, without fertilizer, soil tillage and without soil tillage). The medium soil quality was including land units that present on steep slope, had different land cover vegetation without land managements. The limiting factors of soil quality were texture, C-Organic, CEC, base saturation, N and C-biomass. It was recommended to tillage the soil using hoe and applying organic fertilizer, Urea, and dolomite on the farming area.
