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.

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.

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.

ABSTRACT Inventory of Medical Plants used as Landscape Elements From the Lowlands to the Highlands of Tabanan Regency Tabanan regency is one district that has lowland and highland. Besides, Tabanan still very strong Balinese culture that is still many people who use medical plants not only as a raw material cuisine, but also as an infrastructure for prayer, ritual raw materials, and also as a treatment for balian, but these plants also have beautiful stem, leaves, flowers, and fruits so it can be used as an ornamental plant or as landscape elements, especially at home, in hotels and government offices. Results from this study can be useful for people who want to know the medical plants in the area of the Tabanan regency and the suitability of areas where the growth is suitable in highland or lowland areas. Methods used in this study are literature studies, surveys, observation and identification (observation), survey using list name of plants and data analysis. Research conducted in three sub-districts such as Kediri, Marga, and Baturiti. Results indicated that, based on the altitude there was found several number of medical plants species i.e. in sub-districts of Kediri 43 species, in sub-districts of Marga 26 species, and in sub-districts of Baturiti 15 species. Medical plants in the area usually found in the garden, telajakan, or in tegalan land unit. Keywords: landscape elements, medical plants, Tabanan regency

Potential Study of Yellow Maracujá (Passiflora flavicarva) Suitability on Alfisol Soil The objectives of this study was to determine land characteristics and land suitability for maracujá (Passiflora flavicarva) on Alfisols soil in District of Melaya, Jembrana Regency. The study used the land unit with homogeneus on climate, terrain, and landuse as sampling units. The climate data was analysed by classifying the rainfall degree based on Oldeman and Schmidt-Ferguson system.The characteristics of land were fixed based on the field survey and the soil analysis in the laboratory. Class or sub class of land suitability is based on matching system between land qualities and crop requirements. The results show that land suitability for maracujá (Passiflora flavicarva) commodities is categorized as moderately suitable (S2) with two limiting factors i.e. C-organic and total nitrogen of the soils. Corganic in the soils is needed to keep the balance of the elements and humidity of the soils. The cultivation of this plant, needed at least 74 kilograms organic matter/plant/year.
