Abstract

This study was aimed at investigating the sustainability of subaks in the dynamics of regional development in the metropolitan area of Badung Regency, Bali Province. The data on subak sustainability were collected by using survey method in 69 subaks as the units of analysis, and the secondary data on the factors of regional development were collected by using document recording method. The data were analyzed by using quantitative decriptive technique, Analytical Hierarchy Process (AHP), and multiple linear regression. The results showed that the spatial distribution of subak sustainability levels forms cluster pattern with different dominations in short-, trantitional- and long- distance zones from the  tourism center. The components/elements of Tri Hita Karana (THK) that constitute the first priority in subak sustainability protection are wet land conversion control and guarantee for irrigation water adequacy. It was found that five factors ot regional development have a strong influence on subak sustainability with 87.8% contribution, and the rest (12.2%) is acounted by other factors outside the scope of this study.

Abstract

Recently, the long term development in Indonesia has changed agricultural sector to the industrial sector. This development can apparently harm our own people. This is due to the waste that is produced from factories. The waste from various factories seems to have different characteristics. This defference encourages us to be able to find out different of methods of managing waste so that cost can be reduced, especially in water treatment. In order that industrial development and environmental preservation can run together in balance, many institutions involved should be consider, especially in the industrial chain, the environment, and human resource, these three elements can be examined in terms of their tolerance to waste.

Abstract

The researh is carried out at the basi pillar in Surakarta that is estimated has a clear different at ground water quality. The goals of the research area 1) to know actually the distribution of arial zoning at pollution level of the groundwater; 2) to determine the priority scale of clean water supply. Data analysis used in the researh are tendentious analysis and geographical information system. The result shows that groundwater quality at the research place decreases. It can be proved by tendentious analysis that most of the groundwater quality conentration parameter – after being examined – the lower plae, the higher conentration. There are 21 quality parameters used for that research, 15 out of those have an inclining tendency, while the others are flat and decline. The result of 2 overlapping maps, atual zoning and potential zoning, shows that there is mismatching of risky polluted area. It is caused by human fators, some of them are population density, well construction, bad sanitation, individual septi tank, and industrial disposal from irrigation. Based on the result of the research, clean water district corporation is expected to be able to determine priority scale of clean water supply to Surakarta and its surrounding.

slope of Merapi Volcano in Boyolali. The aims of this study are first to know the characteristic of groundwater in every morphological unit, second to know supplying system of fresh water in every each unit.The method used is survey method. The sampling use to know the characteristic groundwater both quality and quantity of the water, and supplying system of fresh by using area sampling. As basic of stratification of its region is morphological unit. Analysis method used is tabulation, laboratory analysis, and graphic analysis to describe its space.The result of the study shows that the quality of groundwater in every morphological unit is good enough, but in general the contents of element Ca, Mg, N03, CI, SO4, HCO3 shows that the lower the region is, the higher the content of the element . But if it is seen from the depth of its groundwater, so that the fluvial volcanic plain is the shallowest, then the fluvial volcanic foot plain and the last the volcanic foot area. Supplying system of fresh water, which derived from the dominant of well water, is especially used in morphological unit in fluvial "volcanic foot plain. The spring water is used by the population in the morphological unit in volcanic foot plain and then in morphological unit of fluvial volcanic foot plain. The population uses much rainwater in the morphological unit of volcanic foot plain.

Abstract

The development of GPS (Global Positioning System) technology which is measuring position by satellite, has taken a great metodology aspect of position on surface of earth. The standard GPS measurement takes an absolute positioning. To develop the accurate abd precision, it is used the differential method. Differential GPS measurement can be much more accurate than standard GPs measurement, wherever the method uses one receiver as base station/ reference and the other receiver as field station in a same time. That could reduce and eliminate drifts and errors. The aim of research is use the differential method of GPS survey to map the ocean boundary of Central Java Province. Physical data which neede are base line and base point. Base line were taken from obsrvation of longtime Landsat TM image band 5th based o opinion that shore line are clear seems and easy to interpreted at 10.00 am according to Landsat satellite reording time and the lowest tide time as base line. Location of lowest tide were selected at conspicuous place, such as cape, dry shore, etc and measured base on the BPN (Badan Pertahanan Nasional) base/ reference point (orde 2 and 3) on the district, with GPS differential metod. Twelve miles distance from base line of ocean bounddary is belong to province and 1/3 of is belong to district. Characteristic of marine landform as cape, bay, estuaria, attended to international rules. Final report of the research were 1) oean boundary map of Center Java Province, 2) the location and base/ reference points (orde 2 and 3) that could be reference as a base point differential method.
