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

Letak Candi Mendut - Candi Pawon  -Candi Borobudur berada dalam satu garis (imajiner)yang dikenal dengan tiga serangkai. Rangkaian tersebut merupakan sistem tanda yangoleh masyarakat Mataram Kuna abad IX Masehi diberi makna sesuai dengan konvensiyang berlaku pada waktu itu.Membuktikan ketiga candi yang merupakan sistem tanda dengan sebuah makna dapatdijelaskan dengan pendekatan semiotika struktural (Ferdinan de Saussure) yangmendasarkan pada elemen- elemen semiotika yaitu tanda (penanda-petanda), dan porostanda (sintagmatik dan paradigmatik). Elemen tanda dari lingkungan yang dapat dirunutyaitu penanda ruang, elevasi, jenis tanah, dan sumber air, sedangkan elemen tanda daricandi yaitu  arsitektur, arca, dan relief cerita. Tanda tersebut tidak dapat dilihat secaraterpisah-pisah tetapi dilihat dalam relasi dengan  tanda yang lain dalam poros sintagmatikdan paradigmatik. Untuk itu urutan tanda dimulai dari Candi Mendut-Candi PawonCandiBorobudur yang tersusun dalam susunan tertentu (jukstaposisi) dengan masingmasingmakna simbolisnya.Tanda-tandapada Candi Mendut – Candi Pawon – Candi Borobuduryaitu lokasi, tanahbatuan,sumber air,elevasi, arca,dan reliefcerita, tersusun dalam rangkaian yangmemperlihatkansebuah struktur yang bermakna. Susunan tersebut  bersifat linier yaknimengikutiaturan tertentu. Apabila aturan penataan tersebut berubah maka maknanyapunakanberbeda. Hal inilah yang membuktikan bahwa ketiga candi tersebut membentukkesatuanrangkaian perlambang yang mengacu pada makna simbolis berdasarkan konsepajaran agama Buddha pada masa Mataram Kuna abad IX Masehi.

Abstract

Jatiluwih Village and Subak Jatiluwih have been established by the United Nations Educational,Scientific and Cultural Organization (UNESCO) as a part of the World Cultural Heritage (WCH).In addition, the village and the subak (Balinese irrigation cooperative) also have the status asa tourist destination having the potential to conversion of paddy fields. This paper examinesthe knowledge and understanding of the Jatiluwih Village community on the belief and customsbehind the pemali of animal cages in paddy fields, garden in the paddy fields and the mergerof paddy field plot activities in the subak area becoming the part of the world cultural heritage,namely the Subak Jatiluwih. In this case, pemali (customary prohibition) along with the beliefand customs serving as the background is seen as an environmental wisdom.The conclusion in this paper confirms that the pemali mentioned above are still relevant andimportant to be understood and actualized in order to preserve the Subak Jatiluwih and tostrengthen various regulations having been enacted to protect and preserve the elements ofBalinese culture that need protecting and preserving. This strategic measure is to adoptcultural values   contained in the belief and customs that underlie the pemali in the regulationsmade by relevant government authorities and in bylaws (awig-awig) of the Jatiluwih CustomaryVillage and bylaws (awig-awig) of the Subak Jatiluwih.

Abstract

The study area consists of 2 (two) landforms, the hill and the ridge. The hill and the ridge  withslope varied have different rock composition, such as igneous and metamorphic rocks. Besidesthat the landcover of the two landforms also has different variety. These characteristics areexpected to affect the rate of erosion. The purpose of this study were (i) To analyze thecharacteristics of the land parameter from both landforms with different rock units, as thefactors that influence the differences in the level of erosion (ii) To determine the difference ofthe rate of erosion at the igneous and metamorphic bed rocks.Research methodology that have done were survey and mapping. The level of erosion isknown from the results of direct measurements by the method of small plots on each land unit.The survey results revealed that the rate of erosion on the rock units schist (metamorphicrocks) is greater than the unit gabbro rock (igneous). Differences in the level of erosion isinfluenced by rock units, thick soil, slope, and land use.

Abstract

The research was conducted at Badung Regency from May  to  August  2012. BadungRegency determined as the  study  sites intentionally  (purposive  sampling)  withconsideration  Badung Regency is utilizing the highest Ayung river water for irrigation thananother regencies/city in Bali. Water pricing were  analyzed by the Value Marginal Product(VMP) which derived from equation of the Cobb- Douglas production function.  The analysisshowed that the size of area plantation, seed, fertilizer, pesticide, labor and water (irrigation)have real impact on rice production and by using the VMP analysis found that the price ofwater for irrigation is Rp 314.000/ha/season. The price paid is higher than the water fee forSubak, that is Rp 100,000/ha/season for active members and two-time for inactive members.Even the results of the calculations show that the maximum water price paid by farmers isgreater than subak fees, the government can not impose the maximum water pricing approachto the farmers. It is based on the consideration that the agricultural sector is still the sectorthat needs to be subsidized because it involves the interests of a political, economic, social,cultural and religious.

Abstract

The purpose of this study was to determine the effect of the use of rice husk ash as a landfillcover on the quantity and characteristics of leachate generated from landfill lysimeter. Threelysimeters with diameter and height of 0,15 and 2 m, respectively, were prepared. Two lysimeterswere filled with municipal waste and two different cover types i.e. soil (lysimeter A) andricehusk ash (lysimeter B) while another lysimeter was filled solely with municipal waste(lysimeterC). Leachate quantities and characteristics were measured and determined once aweek.The cumulative leachate quantity from the lysimeter B was found to 69,33% and 43,93%lessthan the lysimeter C and Arespectively.Therewereno any differencesof the pH value oftheleachate generated from all lysimeters. The comparison of the leachate characteristicsshowedthat the lysimeter B generate the TSS concentrations 45,95% and 52,93% less thanthelysimeter C and Arespectively,however the TDS concentrations were130,73% and 60,91%morethan lysimeter C and Arespectively.In addition, the use of rice husk ash as a landfillcovercould reduce ± 85% of organic matter in the leachate generated.
