Abstract

AbstractLand use change is one of phenomena which have relation to various environmental issues.Global warming, loss of biodiversity and impact to human life are main issues related toland use change. Those issues have been drive international organizations to developparticular program to study land use change. One of the well known programs is Land Use/Cover Change (LUCC).Working group of LUCC suggested three core subject of researchrelated to land use change. Those are situation assessment, modeling and projecting andconceptual scaling.This research aimed to modeling dynamic of land use change based on spatial simulation.Integration of cellular automata and geographic information system were used to performspatial simulation. Modeling of land use dynamic was focused on conversion from agricultureland to non agriculture land. Three sub districts which are situated at urban fringe ofYogyakarta had been selected as research area. Those three sub districts were Depok,Mlati and Gamping.Time series of land use maps comprising year 1982, 1992 and 2000 as well as populationdata were used to generate input of spatial simulation. Several maps which denote qualityof land were used to develop transition rule. Results of simulation were spatial predictionof land use change for year 2001 toward 2007. It was then validated using land use 2007as reference. Validation test show that predicted and actual condition have fair agreement.

Abstract

Development on each sector would gived negatife effect for environment quality, such as agriculture development to be agroindustry. One of the negative effect of intensification effort through using of pesticide is donate contaminant to water. Identification of suitability agriculture landuse and water polution level by pesticide using is the one effort to save a resource from intensification agriculture efforts. The methods that we was used are analysis spatial for determined of suitability agriculture landuse and contamination indeks for describe how far the water contamination. The result showed that the area where suitable for agriculture in Batu is 1333, 54 Ha or 6,78% and the evaluation result showed there is unsuitable landuse in existing condition is 25,67% from total area, and 32,05% for spatial planning condition. The increased of unsuitable landuse on spatial planning caused by agriculture sector development which the area for agriculture more larger than the land capability, planing for agriculture area is 3289, 76 Ha. Contamination level for water river in Brantas from good condition with IP value is 0.92 on Sumber Brantas and the higest level in Ngujung’s river with IP value is 245,39 with weigh level status. Agriculture intensification efforts also have contribution to reduction water quality on the upper of Brantas.

Abstract

As part of our efforts to move towards sustainable development, it is very importantto encourage the tourism industry to be more environmentally conscious because itconsumes large amounts of resources. One way of achieving greater sensitivity is to identifybenchmarks for energy and water use and for other aspects of hotel operations like theamount of solid waste generated. Benchmarks can be defined using data from existinghotels. The research project focused on tourist accommodation on Southern Part of BaliIsland. It conducted a survey by mailed questionnaire of about 50% of the hotels on theisland. The questionnaire obtained annual data on several sustainability criteria that areenergy and water consumption, biodiversity conservation, resource conservation, cleaningchemical use, solid waste management and wastewater management. The data were usedto derive baseline and best practice thresholds to improve the performance of touristaccommodation on Bali Island.The benchmarks, both baseline and best practice standards were developed mainlyusing the study results which established the average and the average of the top 25% ofperformers. The average of the top 10% of performers was also considered in selecting thebest practice standard for indicators that required stricter standards. Within thebenchmarking process, Green Globe 21 standards and some other studies were also beingused for comparison purpose.In this survey, the difficulties were found in obtaining complete set of data from eachrespondents as well as gaining sufficient responses. Few hotels provided complete set ofdata. Data on energy and water consumption is the easiest to obtain, while data for otherindicators only provided by less than 75% of respondents. Most of the survey resultsshowed reasonable value compared to Green Globe 21 standards. Good performance oftourist accommodation in the survey was found in energy consumption indicator that theaverage and the average of the top 25% of performers were far stricter than the Green Globe21 standards. The study concluded with benchmarks recommendation for each indicatorthat can be applied to tourist accommodations in Southern Part of Bali Island.

Abstract

The purpose of this study was to identify soil contamination by leachate from a landfill (TPA) using geoelectric method. Leachate is the liquid waste arising from the introduction of external water into the garbage heap, dissolve, and rinse the dissolved materials, including organic materials are also the result of biological decomposition process. Leachate contained heavy metals and many other organic pollutants that can contaminate soil and groundwater. Geoelectric method is one of the geophysical methods that exploit the variation of resistivity based on the measurement of potential differences caused by electrical currents injected into the earth. The study began by examining the landfill soil type, then check its resistivity with level of leachate varied, ranging 0-100%, in the laboratory. Furthermore, resistivity measurements in the field to determine the spread of leachate. In addition, examination of pollutant content in the leachate was done. The result showed the soil type of landfill was high plasticity clay (CH). Resistivity value of soil with varies level of leachate was 13.5 to 30 Ωm. On the field, it found value of resistivity soil ranged from 13.5 to 30 Ωm has spread along the 37 m to the east with an average depth of 0 to 1.60 m and 29 m to the south with an average depth of 0 to 1.85 m.

Abstract

AbstractThis research was aimed to analyze the CO2emissions due to forest fires that occurred inSiak Regency, Riau Province Indonesia in 2010 and to analyze the probability of forest fireoccurrence in Siak Regency using the available data. Fire and CO2 emissions in the area ofplantation forests are greater than in the area of natural forests. The amount of CO2emissionsdue to forest fires in 2010 varied between 107.260 Ton CO2 yr-1 in natural forests and151.600 Ton CO2 yr-1 in plantation forests. The amount of CO2emissions due to forest fires inthe peat land was 2.176 Ton CO2 yr-1. This value is mainly depending on the extent of theburned area in the year of 2010. Results of the logistic regression show the forest fires aremore likely to occur in degraded forests.

Abstract

This article aims to look at how market failure can lead to pollution of the turn, cause high costs and how cleaner production program and the creative economy can ensure the improvement of quality of economic growth through green economy with the calculation of Green GDRP performance. This article was written based on information obtained through various sources, environmental journals, teksbook, and some of the research. From the conclusion of this article can be known that market mechanisms fail to prevent environmental risks as a result of failures in the prevention aspect of externalities, public goods and goods the ownership of common property. Implementation of the green economy, in the short term will impact the decline in economic growth, but in the long term economic performance measurement approach green GDRP will impact on the improvement of sustainable environmental quality. Implementation of cleaner production that are more preventive in preventing environmental risks and synergy with the creative economy program will be able to more quickly improve the quality of economic growth through green economic approach. Synergy of four pillars in a participatory manner is necessary in the implementation of a green economy that supported the cleaner production program and the creative economy is the government, business, academic, and community.

Abstract

The living monument in Bali (candi, pura/temple, hermitage cave, etc) has various functions. Since it was built, its function was dominated for religious purpose, especially to pay homage for god/goddess, ancestors, and other holy spirits. The praying purposed to ask for safety and peace, fertility, prosperity, welfare of the followers and the villagers. Besides that function, monument and its environment also utilized to enhance the historical and socio-cultural awareness and science development, and it is also useful for social integration, economic and ecological function. Recently those functions are still maintained and developed on line with socio-cultural and environmental changes. Related to socio-religious function with all of its rituals, later on cultural heritage become a prominent of tourism interest ( destination) in Bali. Besides that, the sacred value of the monument indirectly brings impact to environmental conservation. The conservation of natural environment then contributes to fulfill the monument needs for ritual and building construction. But recently, there is a new trend arising to communities related to cultural values which is showed by behavioral change on heritages conservation. The carelessness of environmental control and conservation, has caused degradation on quality of heritage and its environment. The degradation of ecological and magic-religious values, indirectly will affect the degradation of peace, prosperity and welfare of local communities , and then they are followed by lack of awareness and concern on cultural and natural heritages conservation. In order to cope with the problem, an holistic-integrated approach needs to be applied to manage living monument and its environment in Bali by appreciation on stability and proportional functions of socio-cultural, economic, and ecological aspect in frame of sustainable development.

Abstract

The objective of this research is to develop a system dynamics model that represents the relationship between population sub system and land conversion sub system with freshwater availability sub system in Bekasi Regency. The models are used to predict the relationship until 2025. The models are designed, both with and without intervention factors to population behavior toward water. The purpose of this study is to strengthen water resources management planning in Bekasi Regency. The method of the research was system dynamics. Water availability as a system was represented as a simple model in line with the factors in this research, so that the model represents the real world. The Causal Loop Diagram showed that factors in sub system and inter sub system formed balancing causal feedback loop. Model behavior simulation showed that freshwater availability (i.e. surface water and shallow ground water) decreased substantially (collapse) from 2003 until 2025. The decrease was caused by water pollution rather than the population growth and land conversion increasing. Population numbers increased slowly (growth), while land carrying capacity decreased gradually (decay). It is predicted, if the condition does not change, water crisis will happen in 2018. When community's behavior for water (i.e. thrifty and sanitation behavior) increase begin 2008, it is predicted that beginning from 2009, the freshwater availability will increase, the water crisis can be suspended, and the freshwater inventory can be reserved. Based on those findings, it could be suggested that water resources management planning should consider water as a system and integrate supply side management, demand side management, and governance side management.

Abstract

Sustainable development is a must for Bali. It is due to the fact that one of the negative impact of development is the change of the land use from agriculture into other functions. As a result most of medicinal plants will be extinct. In another hand there is a trend of people to plant horticultures in their house yards. The main issue: is there any relationship between horticulture and sustainable development? In answering it, a field study was conducted in Petiga Village, Tabanan, Bali Province. Observation and  interview were carried out to respondents consisted of five Balinese farmers who nurse cultivate the horticultural plants for their daily activities. Results show that: 1) there are about 159kinds of plant totally used as horticultural plants; 2) amongst those plants, about 67 plants belong to the medicinal plants and 80 plants belong to ceremonial plants; 3) number of horticultural plants in every house sampled ranged from 63-94 kinds; 4) the popularity of any horticultural plant is affected by the market’s demand. The conclusion which could be drawn is that the medicinal plants as well as the ceremonial plants are used for horticultural plants. It is due to their wonderful colors, nice stems, flowers or leaves, special odors, economical values and magical values as well. Horticulture could be used as a strategy for preservation and conservation program of the medicinal plants in Bali. It is recommended that for the sustainability, all medicinal plants which exist in Bali should be invented and planted in a form of medicinal plant park.
