Abstract

One important climate factor for tropical area is rainfall. Changes in rainfall pattern will cause numerous problems especially in agricultural activities and it could also lead to either flood or drought; problems which will not only affect agricultural activities but also socio-economic situation of broad community. Therefore, study of local climate variability focusing on rainfall related to the global warming is important. Time series analysis ( correlogram and periodogram) of daily rainfall was chosen to investigate the phenomena of global warming in local scale. Data (1974-2004) was collected from Sumberjaya, Air Hitam and Fajar Bulan; three stations located inside one of the important watershed in Lampung Province. From the correlogram, in general daily rainfall in this upland and forest area shows independency up to the year of 1990. No seasonal pattern could be an indicator that rains in this area are controlled more by local topography and land cover condition then by larger scale of climate system such as monsoon. After 1990 there were some weak sign of seasonal pattern. This could be interpreted as a sign that larger climate system started influence the local rainfall and as the global warming increases, it could be predicted that local rainfall pattern will be controlled more by the larger climate system. The periodogram shows that rainfall in this area has weak annual periodic. Data from Sumberjaya on 1990-1994 and 1999-2006 showed that annual periodic were getting stronger; a sign that larger climate system started dominating the area.

Abstract

The research conducted in villages in Badung District due to their existence as safeguarder of adat and culture which indicate the changes in the implementation of Tri Hita Karana (THK) concept. It aimed at (1) identifying forms of change in the implementation of THK concept in village settlements in Badung, Bali Province, (2) identifying factors causing the change, (3) analyzing the process of change, and (4) studying the impact of change. In order to achieve its objectives, the research utilized a survey. The methods of sampling consist of: (1) areal sampling, which was based on landscape unit feature and administrative which were selected proportionally, and (2) subject sampling, which consists of the Head of the family determined through stratified sampling technique based on sosial stratification of triwangsa group and jabawangsa. The analysis was carried out using a qualitative technique supported by quantitative data on change in village settlements which were based upon the THK concept. The research results indicated that four elements have changed . First, forms of change in the implementation of THK concept in the mesoscale village settlements occured in the element of parhyangan, pawongan, and palemahan in mountainous and plains are relatively the same. The lay out are in the forms of trespassing the circle of holly areas and the placement of temple in vertical orientation. In microscale, the spatial function of biotic component and social culture is transformed into social and economic function for jabawangsa group, whereas triwangsa still maintains the existence of facilities, lay out, and spatial function on abiotic, biotic and social culture component. Second, factors causing the change in the mesoscale village settlement based on THK concept in mountainous and plains were the form of land exploitation, the vegetation availability, income, and the large of land ownership. Meanwhile, in microscale, the limit of land is the only factor. Third, the process of change in mountainous and plains both the mesoscale and microscale were evolutionary and revolutionary. Fourth, the impact of change existed in the mesoscale mountainous and plains were the decrease of preservation area [biotic] and spiritual degradation, whereas in microscale were decrease of space availability for social component [abiotic], donation pattern, and the transformation from primary to secondary and tertiary sector [social culture] on triwangsa and jabawangsa group. The THK concept as manifestation of local wisdom in village settlements is adaptive to changes and advancement of time as indicated by compromising the kahyangan tiga part as the soul of the settlement while the territory as the physical body of the village as well as the residents. Such a harmony will assure preservation of harmonious environment.

Abstract

One of the most important challenges is preventing and controlling pest and diseases problems, which can partly or completely ruin agricultural crops. Survey done in Bali at three main vanilla growing areas indicated that the stem rot disease was the main and the most destructive disease on vanilla. The objective of the research is to control the vanilla stem rot disease caused by pathogenic fungus Fusarium oxysporum f, sp.vanillae. The test for antagonistic activity by fungi was done through side by side culture and antifungal activity test on vanilla seedlings. Results of this study showed that Saccaromyces sp.effectively suppressed the growth of fungi on Potato Dextrose Agar medium and vanilla seedlings.

Abstract

As a built environment, architecture had faced the challenges that must be answered in 21st century. The most ever whelmingly urgent crisis facing mankind is the degradation of the natural environment. The fragility of the natural environment comes to the fore as a compelling principle for the revitalization of architecture. This study intended to formulate theory or principle that leads architecture to faced the challenge. This is a library research, with logical argumentation & critical methods and Jurgen Habermas strategy. The result hope to be a theoretical alternative in architecture, especially for revitalization in nature and architecture.

Abstract

For water demand, people use dug well getting groundwater stored in aquifer at Pasir Panjang, Kecamatan Kelapa Lima, Kota Kupang, NTT. It situated close to Kupang Bay. Thus the aquifer potentially being seawater intrusion when excessive groundwater pumping. Pattern of groundwater salinity distribution is important data for groundwater management. In this study we applied Electric Conductivity (EC) method to measure saline in dug wells. Location, deep of well and groundwater table data took also. Linier regression analysis show that low salinity found on dug well far from coastline and high saline found nearby coastline. The map with contour line show spatial distribution which different on western and eastern of map. Indicating that high intrusion happened on eastern

Abstract

Plants, especially species of trees, have an important role in modifying the microclimate, particularly temperature and humidity. This study was aimed to evaluate the effectiveness of trees in modifying the temperature and humidity and their interaction in forming the microclimate amenities. There are two methods in the study, first by comparing the temperature and humidity between open space free of shading and under the shade of tree canopies. Sample trees used as many as three trees which are Bunga Sapu tangan (Maniltoa schefferi), Bauhinia (Bauhinia purpurea), and Tanjung (Mimusops elengi). The second method is by making the observation grid which sized 50 x 50 meters that is divided into grids of smaller-sized grid of 10 x 10 meters, then analyzed the air temperature to make the isotherm lines. The study shows that trees can significantly lower the temperature (2.9-7.4 OC) and increase the humidity (0.1-3.9%). Nevertheless, the tree has a limited role and can’t stand alone in order to form microclimate amenity in the environment (THI> 26).

Abstract

Baduy community is a Sundanese ethnic isolating themselves around Kendeng Mountains, South Banten. They occupy an area about 5101.8 hectares of land in which the property rights were granted from the government. The people strictly adhere to their customary rules and norms. The increase of population has resulted in changes in social and cultural aspect of this community. Hence, this study aimed to investigate social and cultural dynamics of Baduy community in managing its forests and environments. The technique of Partisipatory Rural Apraisal surveys were employed in the study. Data were collected by conducting participating observations and open in-depth interviews in the Kanekes Village, Leuwidamar, Lebak, Banten. The results showed that there have been some dynamic changes in terms of social and cultural of the community in managing their forests and environment. These changes were believed to be initiated by the decrease of availability of cultivated areas due to the population growth. The Baduy community started adjusting their ways of life in order to survive. Customary rules (pikukuh karuhun) which were originally applicable to all people have been shifting. The evidence was clear from the obvious differences in the life of the people of Baduy-Luar and Baduy-Dalam. There has been, for example, an alteration in the people’s status in the society. It was all community members that have to obey the pikukuh karuhun rules. However, currently Baduy-Luar community has also been helping to maintain the persistence of Baduy-Dalam’s pikukuh karuhun. Basic rules that must be followed by Baduy’s people include farming procedures and post-productions, the treatment to the forest and environment, and the implementation of the Sunda Wiwitan pillars. These customary rules were absolutely compulsory for the Baduy-Dalam’s people. However, there are some exceptions for Baduy-Luar community members, particularly in relations to fulfilling their daily life necessities. Some socio-cultural changes in the life of Baduy’s people include dress codes, the use of manufactured goods, land preparation methods, variety of cultivated crops and plantations, the use of transportation means, and the design of residential buildings.

Abstract

Untintegrated management and complicated factors lead to problem in Citarum watershed management. The main problems of the research are the management of Citarum’s watershed has been fragmented and conflict among stakeholders. There is need a new concept and approach for managing Citarum watershed so that management of Citarum Watershed more effective. The base proposition of research is Citarum watershed management requires a concept about cooperation among stakeholders than can settle the conflict among them as consequence of fragmented-sectoral management. Based on research analysis, this research formulated some finding. Citarum watershed management are independent, it caused the absence of an institution which functions as leader. Relationship among organizations is ill-structured, caused by overlapping role and function among them. The most appropriate collaboration model for Citarum Watershed management is interdependent model. Research recommendation to rearrangement core task and function of organization base in term collaborative governance.

Abstract

The rapid growth of cruise ships has encouraged the Indonesian government and Bali’s local governments in particular, to compete in developing and upgrading their existing ports. It needs a holistic and integrated transportation system before a decision to locate a port can be made. In order to avoid unconstructive local exploitation to the whole system and given the fact that cruises’ visits are usually only for a short period, requirement for a synergized system is fundamental, in order to measure the whole chain of factors and values involved in the decision making process. Traveling Salesman Problem (TSP) Model implemented in this study is expected to be able integrate tourist destinations and transportation system. Findings derived from this research will be used as guidance in managing many tourist destinations, which include the organization of local traffic and accessibility by introducing alternative routes; managing demands for transportation infrastructures, facilities, and services; reducing traffic congestion; controlling speed limit; mitigating air pollution; and synchronising location of the port and tourist destination. The strategic Environmental Sustainable Transportation is urgently needed to implement in Bali as the major tourist destination in Indonesia in order to minimized CO2 emission

Abstract

Genetic structure and phylogeni of 37 sequences control region DNA mitochondrial cytocrome oxidase I of yellowfin tuna (Thunnus albacores) have been downloaded from GeneBank and analised using Maximum Likehood (ML), Pairwise Genetic Distance and Bootstrapping Phylogeni Model of Kimura 2 Parameter. The result shows that the corrected value of the data was 5,5% and the mean of genetic distances was 3,7 %, where the shortest distance was 0.0% and the longest was 5%. The genetic distances with the out group (Thunnus obesus) ranged between 7,8 % – 9,8 % and with the Thunnus thynus ranged between 10,4% – 12,5%. The value of bootstrap phylogeny of 37 sequences of yellowfin tuna was less than 50%. All those results shows that there was no significant genetic differences of 34 samples sourced from Philipines and 3 from Spain based on sequence region DNA mitochondrial cytocrome oxidase I.
