ABSTRACT
One of the problems concerning food security existing in Banyumas Regency is the level of paddy production. The production of rice produced fluctuates but tends to decrease when the rate of population growth increases. This condition demands the use of the latest knowledge and technology, namely Remote Sensing and satellite imagery data. Grounded on such an explanation, the research was conducted. The purpose of research is: (1) To find out the growth phase of paddy. (2) To find out the results of using the Maximum EVI method to estimate paddy production. (3) To analyze the accuracy of paddy production estimation. The research used the Enhanced Vegetation Index (EVI) method applied to Landsat 8 satellite images and made the variations of EVI value as a source of data processing analysis. The proportionate stratified sampling method was used at the sampling and in the field survey stage. The results of this research are first, the growth phase of the paddy was categorized into four (4) classes, namely water phase at -0.77 - 0.196, vegetative phase at 0.196 - 0.726, generative phase at 0.726 - 0.217, and fallow phase at 0.197 - 0.216, with overall accuracy value at 80.20 %, and which value of the Cohen’s Kappa coefficient accuracy value is 0.7%, meaning that the closeness value of the agreement in each phase is strong (good). Second, the estimation of rice production is 149.120 tons, which is based on the results of multiplication between the harvest area (generative phase) and production value. Third, the results of the test of the accuracy of the comparison of estimates of paddy rice production based on the EVI method in Banyumas Regency, which amounted to 101.05%.

ABSTRACT
Sanddunes in Parangtritis is a unique geomorphological appearance, barchan type particularly can be found in tropical area. Barchan is a type of sanddunes with crescent shaped in both tips like a horn which is a natural uniqueness that should be preserved. Landuse dynamics happened in sand dunes area of Parangtritis during a certain period will affecting the development of sanddunes area. Actual data and information towards landuse appearances in sanddunes area in a certain period is needed for monitoring the sanddunes area development as a part of optimization of land resources utilization. The objectives of this study are (1) to knowing the landuse dynamics in sanddunes area of Parangtritis year 2003-2014, (2) to analyze the landuse dynamics in sanddunes area of Parangtritis year 2003-2014.
This study used qualitative method and concerned at the satellite imagery data processing, in addition, in-depth interviews conducted to gain more valid and precise data also accountable information.
Based on the results that conducted in the conservation area of sanddunes in Parangtritis of 412, 80 hectares. The landuse dynamics map showed the degradation of sand dunes from 216, 11 hectares on 2003 became 37, 98 hectares on 2014 with the sum of degradation area of 178, 13 hectares. The area distribution decreased in the center or core zone of barchan sanddunes because of the unfolded dry land forests. These unfolded dry land forests happened due to the greening programs, settlements, bushes, and shrimp fishponds as the results of local’s activities in sanddunes area of Parangtritis.

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
The Use of Springs by PDAM for Regional Water Supply in Ungaran, Semarang District
No full textThe study was carried out in Ungaran. The goals of this study are to know and to evaluate the potential spring to add drinking water of Ungaran population. This study uses observation and secondary data analysis. The collected data are meteorology data, the water production of Municipal waterworks, the quality and the quantity of springs, the number of population and the customers. The result of the study shows that there are eight springs with the total debit 157 liter/ second or 6739 m3/ day. The Municipal Waterworks uses 65 liter/ second or 5616 m3/ day with the leaking rate 7% or 5222,88 m3/ day and the rest is used for irrigation. The quality of spring is qualified for drinking water requirement. The need of drinking water for per capita of the population is 136.7 liter/ capita/ day. In 2003 the prediction of the number of consumers is about 20.745 persons, so the total need of drinking water is predicted about 2835.8 m3/ day. The total need of drinking water added with the leak water is 3032.36 m3/ day. The Municipal Waterworks fulfils the need of drinking water for the population especially for the consumers of Municipal Waterworks. However, if the number of customers is accounted based on the number of the population in the pipe sope (+ 48246 persons), the Municipal Waterworks will not fulfil the need of drinking water for population, therefore it needs to add volume production of drinking water
