Published: January 2017

To comprehend the factors which influence on the juvenile water, it needs paying attention to the rocks permeability, the thickness of the aeration zone, the type of the material composition and the depth of the ground water. The grade of the ground water quality, both ground water in general and juvenile water in the urban, is dependent upon the natural physical, man made physical, and the condition of the local inhabitant besides the another factors. The influence grade of the factors are undersirable yet because among of them there are cross-linkages. The linkage of the ground water quality condition, besides another factor, inconfirmed by the inhabitant and the settelement. The aspect of the man made physical, both sanitation condition and the population density with their activity effect i.e. sewage by product, should fully determine the ground water quality. There is a closed connection between the juvenile water quality and the settlement condition, mainly, in the case is the domestic sewage disposal. It is estimated that the unit of settlement associates with the grade of the juvenile water quality. Some of the variabilities which are desirable to sustain the settlement condition and constitutes the influence variability i.e. the density of the population and buildings, and the condition of the drainage system for sewage.

Geomorphic Hazard Map for Spatial Planning Purposes
Authors: Taryono T
Published: January 2017

In the planning of spatial lay-out oriented to environmental concept, it requires the information input conneting with the condition of local environment. This condition constitutes the features characteristic of the living space which consist of natural and social environment. One of the natural environment elements, neede to the spatial lay-out planning, is the dynamis geomorphology. The process of the dynami is some times accelerated and increased by natural and anthropogenic factors. The abnormality in both acceleration and the increase will cause a natural disaster, which is based on the landscape approach it is called the geomorphologic hazard. In connection with such event thematic map of geomorphologic hazard describes the disaster susceptibility of an area. The geomorphologic hazard map is an output map whose information is obtainable from thematic map conneting with population, land use, topography, geomorphology, rainfall, hydrological data, and slope classification. Both land use and population maps desccribes the anthropogenic factors. The role of the geomorphologic hazard map, in the planning of spatial lay-out and environmental management, i.e. preventive, represive, rehabilitative, and serves as the basis for interpretation and management of living spere. By putting geomorphologic hazard into map compilation of spatial lay-out (cultural and non cultural area map) a footstep advance is the reached to guarantee human security and their treasures, and human well-being as an integral part of human living prosperity.

Published: January 2017

This paper is an outcome of research concerning spatial differences in forms and coverage of land use in the Progo River Basin. At present the watershed is facing the problem of land use changes from agricultural to non-agriultural ones, leading to the situation of decreasing staple foods. This research is aimed at studying regional variation in the potentials of the research area of the production of staple foods according toland use forms and coverage. Informastion on land use forms and coverage are obtained from the statistical record issued by the Statistical Office of Central Java province and Yogyakarta Speial Provine. As the productivity data on every land use forms are not readily available, the assement on the regional potential is executed on the basis of land use intensity and its apability to produce staple foods. The research reveals that the greatest portion (59 %) of lands in 54 subdistrict in the watershed are highly potential for staple foods production and the rest (41 %) are not potential to moderately potential for staple foods production purpose. The potential for staple foods production in the upper part of the Progo river basin are higher than that in lower part ones. The presence on irrigated land is not always highly potential for staple food production. Although the availability of irrigation water is strongly decisive factor for food prodution (r = 0.661 significant at 99.99 percent), but the presence of built up areas are strongly dictated the potential for food production (r = -0,787 significant at 99.99 percent). The research further shows that the higher the potential for food production, the higher population size (r = 0.791) significant at 99.99 percent). In general it can be concluded that 1) the potentials for food production are determined by the available of irrigation water and the size of the built areas, and 2) the number of population is dictated by the presence of water and potentials for food production.

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.

The crowd of Yogyakarta urban has impacted its surrounding area, including Depok sub district, which is indicated by the rising of physical development, for example education facilities and settlements. The progress does not only bring positive impact, but also negative impact for instance the rising of crime number i.e. motor vehicle robbery. The aims of this research are 1) mapping motor vehicle robbery data as the distribution map and identifying motor vehicle robbery hot spot base on distrbution map; and 2) studying the correlation of motor vehicle robbery hot spot with physical environment phenomena, i.e. land use type and settlement pattern. The research method consists of two parts; they are motor vehicle robbery cluster analysis and the relation of motor vehicle robbery and physical environment analysis. Motor vehicle robbery cluster analysis is using distribution data, which analyzes the distribution into motor vehicle robbery hot spot with nearest neighbor tehnique. Contingency coefficient and frequency distribution analysis is used to analyze the correlation of motor vehicle robbery hot spot and physical environment. Contingency coefficient is used to study the relation of motor vehicle robbery hot spot polygon with physical environment condition, whereas frequency distribution is used to study the distribution of motor vehicle robbery in the hot spot with physical environment condition. Physical environment which consists of land use type, housing density, house regularity pattern, and the average of building size, are obtained from interpretation of black and white panchromatic aerial photograph year 2000, in the scale 1 : 20.000. the most motor vehicle robbery hot spot is found on the settlement area, 68,3% from 378 motor vehicle robbery cases in the hot spot. The seond level is found on the education area (16.4%). The most motor vehicle hot spot in the settlement is found on the hight density and irregular settlement, which have big size buildings. The calculation of contingency coefficient shows that there was a significant correlation between motor vehicle robbery hot spot with land use type and settlement pattern, but it has low correlation value. It means that land use type and settlement pattern have weak influence to the hot spot existence.

Published: January 2017

In 2000, the area of DAS critical land in Indonesia is approximately 23,242,881 ha which consists of forest area 8,136,646 ha (35%) and non forest area 15,106,234 ha (65%). In the contrary, the fact shows that in 1989/ 1990 (the beginning of ‘Pelita’/ the five years development planning owned by the government), the area of DAS critical land in Indonesia was 13,180,000 ha only that consists of forest area 5,910,000 ha and non forest area 7,270,000 ha. The cause and its location of negative improvement of the above DAS has not been predited yet. The one of the causes is the weakness of information system on very DAS management system in the aspect of biophysical, soial, eonomical, and cultural. Therefore, it needs the improvement of DAS management which is supported by the result of research and development. The purpose of this research is to get the potency information and the possibility of sensitivity of the land resources in the frame of DAS management with biophisical land as the parameter. Sub DAS of Merawu (21,860 Ha) isas one of the parts of ‘bulu’ DAS Serayu with stream flow minimum 0,81 m3/second and maximum 108 m3/second. The sub DAS of Merawu as the part of ‘bulu’ Serayu has the type of climate A and B with annual rainfall approximatelly >2,000 mm and it can support everything in the stream flow of in order to prevent the flood. This ondition is caused by the permanent vegetation such as forest, underbrsuh or srub, tea garden, as well as multi – plantgarden that has around 40% happen in the ineptisol land, although precipitous slope and very precipitous (>25%). The technique of land conversation is good enough in its development, mainly in the dry section of the field by using ‘teras gundul’ and ‘teras bangku’ the society near Sub DAS of Merawu is densely populated, its is around 517 up to 827 persons/ square with their main profession as farmer and their income is around Rp 2.000.000 per year. Bya analysing the above DAS management, it an show that sub DAS of Merawu has the potency of water both for internal and external DAS consuming. The potency of using the land for farimng one season in length (class II, III, and IV) consists of around 50,8%. The development multy plant garden (25% area of DAS) is as the type of potential farming effort because of the diversity of both the result and time; besides it is also as the form of protection toward the effetive land. The possibility of sensitivity is too wide land which is susceptible toward the slide (land slide), mainly in the middle part of the DAS. The live dependee of land which strong enough is as the threat toward the future resoures conservation.

There are some characteristics and distributions of unconfined groundwater variation in the research area. Those are related to a system of water supply and consumptive use for drinking water. Variation of the groundwater characteristic depends on variation of morphology. Therefore, it is needed to delineate hydromorphology units of the regions as a base on groundwater resources management, especially for drinking water. The aims of the research are: (1) to study of the characteristic and distribution of unconfined groundwater variations base on landform units, (2) to study the factors that affect such variations, and (3) to establish the hydromorphology units of the regions for groundwater resources management, especially for drinking water. The method used in this research is landform approach and field survey. The sampling method is stratified sampling, based on landform as the analysis approach. Result of the research shows that there are some variations of groundwater characteristic at each landform. Landforms which have good groundwater characteristic are Hydromorphology Unit of Fluvio Volcanic Plain of Young Merapi (except Bayat region) and Hydromorphology Unit of Volcanic Foot Plain of Young Merapi. At those units, there are good quality of groundwater, bicarbonate water (hydrochemical type I), having low electric conductivity, shallow of water table, low in fluctuation, and middle to fast class in aquifer permeability. Those units are the most potential unconfined groundwater resources management for drinking water. The units which have poor groundwater characteristic are Hidromorphology Unit in Bayat Region, including Undulating Alluvial Plain, Fluvio Volcanic Plain of Young Merapi, and Swamp Alluvial Plain. Generally, the groundwater quality is medium to poor, the hydrochemical type is Va (initiation process of connate water) and type III (evaporate water), shallow up to medium of water table, and low to middle class of aquifer permeability. The taste of groundwater is brackish to saline with high concentration of chloride.

The objective of the research is to find the most suitable soil conservation practice that may be applied to control landslide hazard. In order to achieve that objective, some research steps must be done, are: (1) to identify the land characteristics of the study area that is based on the understanding of some factors that caused and triggered the landslide hazard, i.e.: slope morphology, rocks/soils characteristics, climatic condition, and landuse; (2) to study the types of landslide that occurs in every landforms and determine the area having ideal landslide form; The proposed landslide in this research is the process of masswasting down-slope as a result of the gravitation action on materials being sliding. The landslide types is including creep, slide, slump, and rocks/soils fall. The methods that being applied in the research include field survey methods and the method for determining landslide hazard by using geographic information techniques. Field survey method was intended to characterize the location of every landslide that have been happened in the study area. The results of field survey were applied as materials for determinating the grade of landslide hazard. Scorring and weighting methods of factors that influence landslide was apllied to determine the grade of landslide hazard. Scor and weight were not same for every parameters used for evaluation. The result of field research shows that landslide happen in every landform unit The study area can be devided into 9 landform unit. The landform units are differentiated into the landslide hazard classes, the study area there were found 5 classes of landslide hazard, namely: (1) vary low hazard equal to 16,65% (1 landform unit); (2) low hazard equal to 7,63% (1 landform unit); (3) medium hazard equal to 37,58% (3 landform unit); (4) high hazard equal to 25,41% (2 landforms unit); and (5) highest hazard equal to 12,73% (2 landform unit). Evaluation of landslide hazard shows hat most of study area have high risk to slide as a result of complex interaction between many factors of landslide.

The wetland has a strategic role in national development. The potential uses of the wetland are varied such as for agriculture, fisheries, industries, and forestry. The intensive use of the wetland for agricultural development in Sumatera, Kalimantan, Sulawesi, and Papua through transmigration projects has been run since in 1973. Unfortunately, not all the projects were well developed, causing the social, economic, and physical environmental problems. These problems resulted in the negative impact for the life of the transmigration people. For that reason, the community empowerment for the unlucky transmigration people by handling the physical and non physical aspects is very important. This paper will describe the importance of providing spatial data and information biophysical wetland as an initial step in empowering people who live in the wetland resource.

One of the impacts of coastal region development is settlement change. Because of that, this article presents a result of research about changing of settlement land area, house buildings, settlement facilities since 1996 up to 2003, and several factors which influence to the changing. This research was carried out in 20 karst villages borders on Indian Ocean so-called coastal villages in of Gunungkidul Regency as analysis units. Data analysis employs so-called secondary data analysis method, using Village Potentials Cencus (PODES) data were published in Statistics Central Bureau. Data analysis employs frequency, cross tabulations, and statistical analysis. Result of this research shows that as long as 1996 up to 2003 the settlement land area increases on 0.24 % per annum on an average, while the house building number on 6.14 % per annum. Spatially several coastal rural villages are near or as a tourism object or as a district office locations are higher developing than the others of coastal rural villages. It means that the development of tourism objects as long as 1996 up to 2003 has influenced the coastal rural settlement development. Generally, the development of coastal rural settlement is significantly also influenced by thirteen of physical and socio-economical factors (R=0.903; Sig.=0.05). In detail however, among the 13th of physical and socio-economical factors are only five factors significant influence to the development of coastal rural settlement. The 5th factors are the average of place elevation, well number, propotion of agriculteral land area, household densty, and population density. Based on that findings in order to develope of coastal rural settlement especially in karst region, besides the development of tourism objects, the five factors should be taken in consideration.

Settlement is the most important area in the activity of disaster mitigation. The Biggest detriment caused by disaster is generally placed at the settlement or residential area. Thereby, the identification of the settlement characteristics is required to be able to recognize the disaster risk. This research aim to identify the characteristics of the rural settlement on the coastal area in the District of Kulonprogo. This area is chosen based on the consideration of coastal morphological characters. This area have slopeslightly coastal zone which face to Indonesian Ocean. In this situation, hence in the event of tidal wave, there will be wide spread overflowing run up water. Two approaches is used in this research, they are; (1) Morphological Approach, and (2) Behaviour Approach. Both of the approaches is conducted with comparative perspective. The existance of the settlement which have been filtered through settlement and coastal tipology are compared. The data are collected and analyzed through: (1) Mapping and GIS tools; (2) survey method; (3) Indepth interview; and (4) statistical analysis. Thirty household are selected proportionally to setlement unit as a respondent in indepth interview. In order to analyze the data, descriptive analysis (frequency tables) and crossed tables are used. This research indicate that rural settlements on the coastal area in the District of Kulonprogo are spatialy distributed as a ribbon pattern. This pattern are coincident with the shape of the coast and the linearity of the road as well. Most of the buildings are in good condition, and they characterized by moderate housing density. In the term of coastal morphology, the research area is dominated by sandy coast with slopeslightly relief. Generally, the socio economic condition of the peoples living there are low to medium economic level, low education, and rarely medium income. Related to tidal flood vulnerability, this research area is the second level (moderate) hazardeous zone.

Published: January 2017

137Cs radiogenic content in the soil can be used to estimate the rate of erosion and deposition in an area occurring since 1950’s, by comparing the content of the 137Cs in observed site with those in a stable reference site. This experiment aimed to investigate the influence of cultivation type on distribution profile of 137Cs and distribution of erosion and deposition rate in cultivated area. A study site was small cultivated area with slope steepness <10o and length 2 km located in Bojong – Ciawi. For this purpose, the top of a slope was chosen for reference site and three plot sites were selected namely Land Use I that using simple cultivation, Land Use II that using simple cultivation with ridge and furrow, and Land Use III using machine cultivation. The results showed that cultivation could make a movement of 137Cs to the deeper layer and ridges and furrows cultivation system could minimized an erosion process. The net erosion and deposition for land Use I, II and III were -25 t/ha/yr , 24 t/ha/yr and -58 t/ha/yr, respectively.
