Abstract

The objective of this paper is to describe the relationship between CG (Cloud Ground) lightning observation data to rainfall in Java region. CG lightning data obtained by using Lightning Detector that is able to track low frequency of radio signals from electrical processes lightning discharge and installed in Bandung Geophysics Station. For better resolution, data is limited within a radius of 10 km square of study area. The results showed a strong relationships between CG and rainfall (r2 = 0.9) and the dominance of CG+ compared with CG- throughout the season with a peak in the MAM (March-April-May) for Bandung (40.6%) and DJF ( December-January-February) for Semarang (48%). Understanding of the peculiarities of lightning activity will provide important information in the structure, the growth of clouds, atmospheric labilitas or as a warning extreme weather. Therefore, it is possible to utilize CG lightning as predictors for rainfall prediction.

Abstract

The purposes of the research are to know the composition, distribution, and dominantspecies of vegetation at Batukaru forest conservation area (RTK-4). This research usedtransect method done by systematic plot sampling. Five transects were made, that was thedistance of 1 km each transect line. In each transect line there were 10 plots with the dictanceof 100 m each plot.The result of the experiment found 33 kinds of higher plant to cover the field on Gesingvillage and 18 kinds on Bukit Catu village, with Podocarpus imbricatus Blume is thedominant species on the both villages, with each the important value index of 88,82 % and99,47 % for the higher plant, so that species not stable yet. The lower vegetations thatidentificated on each location are 27 and 34 kinds of speciesDiversity Index on some level of plant growth at Gesing and Bukit Catu villages arearound 1,88 (sedling) – 2,77 (tree) and 1,77 (sedling) – 2,11 (tree), so the communitycondition is in the term of stable.

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

AbstractDevelopment of crude palm oil industry in Indonesia and Malaysia have been able tochange the map of world vegetable oil in a short time. In 1985, Indonesia palm oil productionreached 1.3 million tons. However, in 2007 Indonesia has surpassed the total production ofCPO Malaysia. Indonesia’s CPO total production in 2011is 23 million tons. To producethat amount of production volume, there are at least 4 million ha of land to produce rawmaterial for the factory. With the next target of 50 million tons of production will of coursebe a lot of land to be prepared or converted. However, the increasing of CPO production isnot always have a positive impact. Forest damage caused by the opening of oil palmplantation and is still a lack of consideration to increase CPO production through increasedproductivity of the land received many responses from various parties environmentalists.Approximately 400,000 ha of forests in Indonesia per year be converted into oil palmplantations. The use of forest land for oil palm plantations is one of the growing threat ofIndonesia’s CPO production so necessary to control the development of this industry.Thispaper provides an alternative optimal solution to the development of palm oil industry bybuilding a decision support system that integrates GIS with spatial analysis modelsesspecially multicriteria decision making. This spatial based decision support system has acapability to accommodate the limitations of land development, environmental constraints,transportation facilities and transportation networks as well to get the optimal CPO industrydevelopment decision.

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

Efforts made to achieve clean and healty environment should not merely put on the responsility of executive institutions only, but also all stakeholders who have concerned on environment including house of representatives. The Environmental Caucus of the house representative are expected to improve survailance, budgetting, as well as release of pro-environment regulations which are predominantly related to environmental management. On carrying out sustainable development, providing main attention on environment on any decisions and regulations made is a must. Therefore the existence of Environmental Caucus of the house representative is important because the institution can push any parties to make decission which are pro to the environment on the parliament levels. If we look at the challenge and chance faced by the Environmental Caucus of the house representative, strong commitment needed by their members to fight for pro-environment supporters and take environmental problems as priority on their political agenda.

Abstract

A study on evaluation of implementation of concept of environmentally and culturally friendly tourism based on Balinese life phylosophy of the “Tri Hita Karana” (THK) has been undertaken at Fivelements (Puri Ahimsa) hotel, in Mambal, Badung Regency, Bali between September and October, 2011. Data were collected based on on site observation by reserarchers accompanied by conducting interview to management and employees and checking documents. Evaluations were undertaken refering to evaluation checklist measures of the THK Tourism Awards. Results of the evaluations were then classified into excellent, good, moderate, fair/pass and fail (affiliate). Results of the study showed that the implementation of the THK phylosophy at Fivelements were classified into excellent with overall performance score of 93.33. The score acchieved by Fivelements in general was better than those of hotels participants of the THK Awards in Bali in 2009 (86). From the three aspects, achievements of implementation of THK for community aspects (pawongan) at Fivelements was the highest among others, with the performance score of 96.67. This better that performance of cultural aspects ‘parhyangan’ with achievement score of 96.00 and environmental aspects ‘palemahan’ with achievement score of 85.56. Accross the three aspects of THK (culture, community, and environment), achievements for environmental aspects were observed to have most number of points need to be improved, that was on 50 % of its existing checklist measures. Meanwhile for the culture and community aspects, the hotel performance may still able to be improved on 13 % of its measure checklist points. On environmental aspects, the lowest score achieved was 2 out of maximum 5, ie. on checklist L.13 whcih refering to handling of hazardous materials. On culture aspects, the performance of the hotel which got the lowest score of 3 was on checklist point H.2, which was dealing with availability of shrines within the temple. On ‘pawongan’ (community) aspects, the lowest score achieved was 3 on checklist point W.16. W.16 checklist point was dealing with length of stay. Length of stay of guests in the hotel in average was between 4 and 8 days, the parameter of which was expected should be more than 12 days.

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

Marine life and natural scenery - in the category of nautical tourism - are the potentials of the Kelapa Lima, Kupang beach. However, there are problems that; construction progress, residentials and bussines activities nearby coast of Kelapa Lima, Kupang, indicated that there are contamination by wastewater into the waters of this beach. Then, this issue is adjusted to the standards Environment Minister Regulation number 51 of 2014 and in 2013 number 115 on the sea water quality standard. The method used is the equation written by Sumiotomo and Nerow (1970) in the Minister of Environment No. 115 of 2003. The formula that is used to calculate the results of studies measuring the location parameter with the default value determined by the Ministry of Environment in 2004. Later, research shows that the quality of the waters of the Pantai Kelapa Lima Kupang has begun to decline in the presence of contamination by sewage. Liquid waste is already affecting marine life that corals and mangroves, while the beauty of the sea coast, the liquid waste is already reducing the amount of oxygen for the oxidation process that takes coastal sea to the decomposition of waste into the sea, causing sedimentation affect water clarity sea shore. Therefore, there needs to be immediate action from the government to educate more people about the importance of maintaining the beauty of the beach, and helped make the disposal of liquid waste discharges in coastal areas to reduce the causes of liquid wastes into the coastal sea.
