Abstract

High population density is the main factor in environmental problems, where the high speed of human growth caused the vegetation area became deminishing. The aims of this research was to functionized the ALOS/AVNIR-2 image satellites and GIS to calculate the percentage of vegetation in Denpasar city with three index vegetation formulas: NDVI, SAVI dan MSAVI in order to get one formula to build the distribution map based on the percentage of vegetation. This map was used to evaluate the urban planning map 2003 in Denpasar city. Result showed that there was relationships between vegetation index of ALOS/AVNIR-2 images and percentage of vegetations, where the vegetation index of NDVI and SAVI had the highest coefficient determination. The formula of “Percentage Vegetation = 132.71 (NDVI)2 + 3.461 (NDVI) + 5.6775” was used to generate the percentage distribution vegetation map. Based on that map, the dominant vegetation distribution found in settlement area (with percentage vegetation area) lower than 25%. The urban planning for green open area “KDB” 0% was dominated by the area which had a percentage of vegetation between 25-50% and 50-75%. In the other hand, the urban planning for “Tahura”, was dominated by the area which had a percentage of vegetation of more than 75%.

Abstract

In this study, the use of SPI (Standardized Precipitation Index) combined with remote sensingdata is performed to map vulnerable drought areas in Bali-Nusa Tenggara regions. Analysisalso carried out to find the relationship between Vulnerable drought areas in Bali-NusaTenggara with El Niño phenomena. Bali-Nusa Tenggara islands are a chain of islands thathas a semi-arid climate type and resulted vulnerable to meteorological drought. Therefore,mapping of vulnerable drought areas in the region necessary to be carried out. The spatialpattern of the annual average value of SPI-6 in Bali Nusa Tenggara areas in 1998-2010indicates the spatial distribution follows the ENSO events. It also indicated in the spatialpattern relationship between ENSO and SPI in Bali-Nusa Tenggara islands. This studyindicates that remote sensing data such as TRMM 3B43 has the capability to be used as adata source to analyze the spatial patterns of vulnerable drought areas, particularly in theBali-Nusa Tenggara Islands. In addition, the TRMM data also possible to be used as a datasource to analyze the vulnerable drought areas in other parts of Indonesia.

Abstract

The research aims to reveal the trens population growth over the 10 years (2002-2012) inTabanan Regency, as well as their impact on the land conversion of subak as well as otherchanges in environmental and cultural aspects of subak. Research conducted through thestages of data collection and data analysis. The technique of data collection was done bythe library research, observation, and structured interviews with questionnaires and indepthinterviews (depth interview).The data collected was analyzed by descriptivequalitativeand quantitative analysis with the help of cross-tables and analysis of satelliteimagery.Resultsof the study showed, the number of inhabitants of TabananRegency in 2012 reached441.900people, consisting of 220. 002-sex guy men and 221.898 women. The livelihoods ofinhabitants,mostly working in the agricultural sector (110.449people) and plantations(45,326people). Based on analysis conducted, it was revealed that within the last 10 years(2002-2012)population growthreached26,10% or = 2.61% per year.The highest growthoccurredin the district of Kediri 5,76%, then followed by district of  Baturiti 5.13%, Marga4.05%,and district of  Tabanan,3,69%. The lowest population growthoccurredin districtPenebel0.34%, then followed by the district of Kerambitan 0,56% and district of EastSelemadeg0.82%. The population growth seems to be more of a factor caused by migration(peoplecoming) 62,24% (1294 inhabitants) (from the difference in population that comes3293with people out 1999 inhabitants), if compared with population growth naturallyonlyachieve 37,76% (785 inhabitants).Thepopulation growth indirectly affects the occurrence of changes in the environment andcultureof subak. In the past 10 years occurred the shrinking land subak (fields) 672,89 ha,or2.95% of the total area of paddy fields in 2002 (22.842 fare ha). Other environmentaleffects,i.e. reduced water supply and the breakdown in some irrigation farmers, pollutionandthe impact of irrigation channel blockage by garbage plastic and aesthetic degradationofthe environment. Socio-cultural impact of subak, which tendency to the occurrence ofsocialconflict, disruption in the silent  ritual of rice fields (penyepian carik) and theabandonment of cultural heritage (pura subak) due to the occurrence of function fields intohousing and tourism facilities.The protection needs to be done to the environment and subak culture through the populationgrowth control with government policy, the formulation of customary law of subak (awigawig),and improve the welfare of farmers through the development of ecotourism that basedonsubak ecosystem.

Abstract

The Unda River (Tukad) is the second largest river in Bali Province after the Ayung River. The Unda River has been used for various activities, such as tourism activities for white water rafting and agricultural irrigation activities. In addition, Unda River water is planned to be used as a raw water source in the planned construction of the Bali Cultural Center (PKB) which is planned to be built in the lower reaches of the Unda River. Therefore, it is necessary to conduct research related to the water quality of the Unda River, especially in the Lower Unda River. Water quality analysis refers to class II water quality standards according to the Bali Governor Regulation Number 16 of 2016. Meanwhile, the analysis of water quality status uses the pollution index (IP) according to the Decree of the Minister of the Environment Number 115 of 2003. The results of the analysis show that water quality parameters that exceed the highest quality standard is downstream (sampling point 3) with 4 (four) parameters, namely Total Dissolved Solid (TDS), chemical oxygen demand (COD), total coliform and fecal coli. While the sampling points 1 (one) and 2 (two), the parameters that exceed the quality standard are total coliform and fecal coli. In addition, the results of this study also show that the pollution index value downstream is increasing, where at sampling point 1 which is a DAM location has a pollutant index of 3.78 (light pollution) and at sampling point 2 of 6.27 (moderate pollution) and at sampling point 3 of 7.67 (medium polluted).

Abstract

Peningkatan CO2 di atmosfer yang berpotensi menghasilkan pemanasan global telah menjadi perhatian bagi kehidupan manusia. Lautan mengandung lima puluh kali lebih besar CO2 daripada atmosfer dan menjadi penyangga yang membatasi konsentrasi CO2 dalam atmosfer. CO2 mengalami perubahan secara terus menerus antara udara-lautan dan konsentrasi CO2 di dalam laut dikendalikan oleh parameter fisika, kimia, dan biologi. Perubahan konsentrasi CO2 antara udara-lautan dapat ditentukan dari interaksi gas dan perbedaan konsentrasi CO2 antara udara-lautan. Perubahan CO2 antara udara-lautan dapat dikaji dari studi kecepatan angin, koefisien gesekan kecepatan angin yang diperoleh dari satelit ALOS/PALSAR di daerah Selat Badung dan Selat Lombok, salinitas, dan juga dengan SST yang diperoleh dari satelit MODIS. Hasil analisis menunjukkan bahwa koefisien perubahan CO2, perbedaan tekanan CO2 antara udara-lautan, dan CO2 flux antara udara-lautan secara berturut-turut yaitu 0.303±0.006 (rata-rata±standar deviasi) (mol m-2 month-1µatm-1), 17.94±10.79 ?atm, and 5.35±3.26 (mol m-2 month-1), dengan nilai maksimum dan minimum dari koefisien perubahan CO2 secara berturut-turut terjadi pada bulan Agustus dan Februari.

Abstract

The issue dealing with climate changes has been becoming more stressed out along with more frequent of the occurrence of extreme weather as a consequence of anomaly climate. Examples of anomaly climate that often related to extreme weather are El Nino and La Nina. One of methods to find out the condition of El Nino and La Nina is by observing SOI values. Methods utilized in this research were by collecting rainfall data and SOI values along with regresion analyses to observe the determination coefficient values (R2). Results of this research showed that the rainfall variability on the research area did not affect fluctuations of SOI values on rainy seasons except in Munduk, while on dry seasons it was very clear shown, except in Gitgit. On the transition period, the influence of SOI values on rainfall variability was seen differ on every rain stations. On the first transition period (April), the fluctuation of SOI values had seen clearly being influenced on Baturiti’s rain station and was not influenced on Gitgit’s rain station. On the second transition (October), the influence of SOI values has affected Munduk rain station and did not influence that on Candikuning rain station. The research’s location that covered an area with monsoon rain paterns, the presence of Walker cycles, and ITCZ were also affected the results.The position of rain stations on a certain topography or location also influenced rainfall variability, so it can cause the difference on SOI values on each season.

Abstract

Aquatic organisms or nekton have an important role in supporting the stability of the aquatic environment and human life. This study aims to determine the nekton type community, ecological index, and their conservation status in the Unda River area and around Jumpai Beach, Klungkung Regency, Bali. The study was conducted in July - August 2020. The study was conducted in 2 communities, namely Macrozoobenthos and Nekton. Macrozoobenthos samples were collected using the quadratic method in the Jumpai Beach area and the direct observation method along the Unda River. Nekton communities are collected through primary data using "survey methods" and secondary data through interviews with fishermen and local communities. The ecological index data were analyzed using the Shannon-Weiner diversity index (H'), dominance index (C), and uniformity index (E), while the data on Nekton type and conservation status were analyzed descriptively. The nekton species community in the waters of the Unda River and Jumpai Beach areas was obtained as many as 26 species in 21 families which were dominated by Kepala Timah (Aplocheilus panchax) and sepat rawa (Trichogaster trichopterus), while Nautica sp for the Macrozoobenthos community. The ecological index of the aquatic community is the Shannon-Weiner Diversity Index (H') value of 2.98 (moderate), the wealth index (R) of 3.95 (moderate), and the evenness index (E) of 1.21. (High). The highest percentage ratio of nekton communities was obtained by the Macrozoobenthos community, namely 53%, while the nekton species was 46%. Conservation status shows that 13 species are included in the LC (Least Concern) category, 12 species are included in the NE (Not Evaluated) category, and 1 species are included in the VU (Vulnerable) category.
