The housing environment problem is the inreased population and housing density  in certain areas, as a consequence of the high population growth rate. This situation has brought about the unavailability of the existing public facilities. Such as the evironmental problem is also faced by Bantul regency. Starting from those stated environment problems, this study has in phased its general objectives on to comprehend the variation of housing environmental quality within various topographical, and to comprehend environment factors influencing the housing environmental quality within various topographial background.this study employs so-called sampling technique. Area sampling is carried out aording to topographical condition. Ten villages are randomly selected representing the sampling areas. The number of respondent is 300 households, selected proportionally based on the area stratification. Primary data is collected direct communication with informants are key persons. Data analysis employed simple correlation technique, multiple regression analysis, and one way variance analysis. The study reveals that differences in topographical characteristics are strongly associated with the differences in the quality of housing environment. The level of village development is also the main variable determining the quality of housing environment. A significant different of housing environment quality both among various topographical zones and various level of village development is reported. The achievement of programs oriented to village environment improvement is varying according to the distribution of village on the topographical zone. A greater success is commonly achieved by villages located in the upland and low land than those in the hilly areas. The social-economic condition of the dwellers is determining the quality of housing environment. Nevertheless, differences in the contribution of various variables to housing environment are encountered. In the whole areas, whether it is lowland, hilly or uplands areas, the family inome to be the first important facctor determining the housing environment quality.

Published: January 2017

The Alabio polder irrigation which area of 6000 ha is situated at the Negara river basin in Kalimantan Selatan province, consist of agricultural land which major part is approximately used for paddy-fields (60%), swamp zone (30%), and other (10%). During rainy season are usually flooded, which water level of 0,50 – 1,50 m above the ground surface. The flooding is due to the slight slope of the Alabio, Panggang, and Negara river. During field investigatiton period from Desember 1989 to Pebruary 1990, inflow discharge measured in the Tabukan intake was 14,9 – 17,1 m3/det, which water elevation was 2,62 – 2,74 m MSL, in Mahar intake was 0,52 – 2,67 m3/det, which water elevation was 2,94 – 3,25 m MSL. The outflow discharge measured in the Kalumpang drainage main canal was 1,68 – 17,1 m3/det, and in the Luang drainage canal was 13,62 – 16,92 m3/det. The Alabio Polder outside slope was 0,00011 – 0,00025, the inside slope was 0,00002 – 0,00010. The difference of water level elevations for the various discharge in the Alabio canals network is due back water in the downstream Polder area. Sedimentation was accour in the intake and drainage canals. The chemical analyze show that surface water meet to the standard for irrigation. The hydrologycal optimation and water balance study should be necessary.

The Effectiveness of Canopy Trees to Reduce Rainfall Acidity in the Industrial Area at Medan
Authors: Basuki Tyas Mutiara
Published: January 2017

The term of acid rain is referred to the mean rainfall with a pH less than 5,65. The element of Sox and Nox are the major sources of aid rain. These two elements are oxidized into SO4 and NO3 respectively in the air. Sulfate and Nitrate are water soluble and the primary sources of hydrogen ions in acid precipitation. Rain passing through a tree canopy may lose or gain mineral elements trough some combination of natural process of absorption and leaching. By this process, the canopy may reduce rainfall acidity and negatif effects of the acid rain which will enter into the soil. Due to characteristic differences among tree canopies, a study to evaluate effectiveness of the trees in reducing rainfall acidity was done. In this study, rainfall and troughfall were collected every single rain and the pH measure by portable pH-meter. Based on data collection during 3 months in Medan Industrial Estate, it found that the mean pH of rainfall was 5,15. The highest pH of throughfall was found from Gnetum gnemon, that was 5,70; following by Mimusops elengi, Filicium decipiens, Acacia mangium, and the lowest was Nephelium lappacum. G. Gnemon was able to reduce 11% of rainfall acidity, but N. Lappacum caused 13% increasing rainfall acidity. In this study, the main source of rainfall acidity was hidrogen from sulfate acid (54%), following by chloride acid (30%), and nitrate acid (16%).

Land is natural resources within processing needs to the wise action in order to give good returns for human and being prevented it’s conservation. In the utility of it’s land this land is proper to the agriculture land have sometime emergedthe environment problems, namely the balance of nature is disturbed. It doesn’t mean that land is forbidden to use, but in the it’s utility purposes this land must be considered it’s capability or it’s balance. If form and manner of using this land doesn’t disturb the natural balance, it means to be guaranted. In the countrary, if form and remain to be guaranted. In the contrary, if form and manner of  using this land disregard with it’s capability, then the natural balance is disturbed, the land is called asland within dangerous condition or critical land. The coresponding  problem that arises in Kecamatan Cepogo under Boyolali district on the surface level land and southern land resembles the critical land that the most erosion appearance can be found assuch sheet erosion, gully erosion, erosion in the other side, vallage forest, settlement land. Mixing estate and the infertile land. This recent exploration purpose is to understand physical factor that affects the critical land as well as to collect and to clarity the critical land. The used method is survey and laboratory analysis by land unit approach ascartography unit. The adopted data of this research is used the effectively width of soil, texture, soil permeability, soil slope, and soil appearance. From this research is understood that the explorated land has three critical land levels, namely; the medium critical land level is 4411,09 are or 17,48%, the wight critical soil level is 7909,74 are or 12,86% of the whole exploration area wide.
Identification of Environment Chase in Surround of Sermo Reservoir; and the Inﬂuence Possibility for Function and at the Age of Reservoi
Authors: Sudarmadji Sudarmadji
Published: January 2017

Sermo reservoir is the only one belongs to Yogyakarta Special Province; it is relatively a new reservoir with the area of 1.9 kilometer square and its capacity of 25 million cubic meter: It started to operate since 1996 as flood control, irigation, water supply, tourism and ﬁshery purposes. As a reservoir it could be considered to be a manmade lake, as its condition nearly similar to a lake. Since it operated (even during construction period) there were some significant environmental changes within the reservoir and in the area around the reservoir due to the human activities. These changes could threat the sustainability of the reservoir itselfThis research aims to identiﬂr the human activities living around the reservoir and visitors coming to the area, and to evaluate the potensial of the activities to produce wastes which is discharging in into the reservoir; which may threat the sustainability of the reservoir: The observatorium in the ﬁeld has been conducted in the area of the reservoir and its sorrounding. I t was ﬁrund ﬁom the observation that activities o f ﬁshery using net (karamba), tourism altogether with its facilities, land use around the reservoir for agriculture purposes, mining of class C ore, have given a lot of contribution to wastes (liquid and solids) and sediments into the reservoir: Those activities may cause water quality of the reservoir lo decrease as well as reducing the reservoir depth. Those situation was observed in the northern and north western parts of the reservoir Water quality degradation of the reservoir may threat reservoir as source of domestic water supply, while the sedimentation may reduce the life time of the reservoir The fishery and tourism activities was estimated as a main cause of water quality degradation, beside agricultural and domestic wastes originated from sattlement area around the reservoir: Sediments coming into the reservoir are derived ﬁom transported and movement of materials from land slide occuring around the reservoir; due to distruction of land in constructing the relatively new ring-road close to the shore line of the reservoir: Of course, the sediment is also coming from rivers enteringdie reservoir. Sermo reservoir is a relatively young reservoir; the early observation of environmental changes of the reservoir could hopely be used as indicator to study ecological changes of the area within and around of the reservoir; and could be used as a comparison to other reservoirs, as well as basic environmental management of the reservoir and its surrounding.
Occupation Change of Farmer to Fishermen: A case in Coastal Rural Area in Gunungkidul District
Authors: Ritohardoyo Su
Published: January 2017

Utilization of marine resource is one of type of farmer coping with critical land in coastal 47% The consequence of this, is the change in their occupation status from the farmer to ﬁsherman However the change does not always mains that their poverty status may also changes. This factual problem is the base for research objectives, with the main emphasis on understanding farmer motives of changing occupation to fisherman, process variation of occupation change, and the impact of this process to household incomeThe research was carried out in six coastal village of Gunungkidul Distric. Survey method was employed by collecting data from respondents. The population of respondents amounted to 341 households (HH) working as ﬁsherman Sampling technique was proportionally simple random in which 120 HH was taken as mpondents sample. They were representazivis of Kanigoro, Pucung, Kemadang, Ngestiharjo, Sidoharjo, and Purwodadi villages. Data on socio economic structure of the household, the process of occupation change, and household income were collected by mean of structured interview. Data analysis was performed through descriptive technique in which frequencies and cross tabulation were mostly used.The research results indicate that the motive of local farmer to become fisherman are various, but the main motive (81,7%) to increase household income. The major cause of this is physical environment pressure of the area (ie. critical land and backward village). This leads ﬁirmer to low level of accissebility to socio-economic inﬁasructure, and low level of economic status or very poor category. The majority of farmer (58,3%) carried out transitional occupation beﬁare becoming ﬁsherman. This encompass activities as ﬁshing or collecting sea shell and lsea algaemn the sea front Intermediary activitis being perﬁmned a form of adaptation to marine environment (sea water) from agricultural land environment. This means that most farmers search and gain skill and experiences related to fishery. Occupation change from farmer to ﬁsherman has significant impact in the betterment of income. In average, the ﬁsherman monthly income is Rp 531,375 which is much higher than the minimum level of basic need in Yogyakarta Povince (Rp 266,870.). In the other word the occupation change from farmer to ﬁsherman driven by motive to increasses household income is proven to be capable to statisfy the need if household economy.

The objective of this study is to ﬁgure out whether it is true that there is a relationship and influence between family education, occupation, family income, religion, orientation, society institution (LKMU) and also nature resource such as land and water toward the indication of dwelling environment development which are also as a cultural changing.The method that is used in this study is Purposive Sampling which determines the location survey. The source in this study can be divided into two parts, those are the primary data and secondary data The primary data are obtained by applying interview to 40 heads of family from Kampung Gemblalean Bawah and Cokrodirjan, and 40 heads of family from kampung Ledok Tukangan. The secondary data are from the related institutions.In the analisys the writer needs to employ the multiple regresion and correlation technic to deﬁne the relationship and influence between the social economy factors and the culture. The result of this study shows that since 1965, during the development order, the development of houses that is considered as the culture phenomenon is in progress.The analisys shows that there is a significant relationship on the family income factor in Tegalpanggung but there is not in Suratmajan. The multiple regression analisys displays that it has a positive relationship on all factors including social economy factor in both locations, but it becomes doubtful after each R Square analisys contributes more or less 20 percent only. It is because of the historical background of society in both locations. They were migrants and now live in their ancestral hams. One of their typical characteristics is that they still have an orientation to their origin places. Therefore the houses they live in now tend to he temporary houses for short-term settlement.TheAMD Program (one of Indonsian Government Program which concerns Indonesian Army/ABRI to make a community service in the village), could manipulate the condition by guiding the people to carry out the public necessity such as ﬂood preventive. The ﬂood always threatens the sojourn, dwelling house and their environment with destruction. This program is eﬂective to inﬂuence the people mattitude and behavior to make a forward movement in house renovation and environment maintenance. The rsult emphasizes a new atmosphere of cultural dimension, which is caused by a power distance, in this case, interest group, so that enables the people to have culture progress.

Emerging concentration of COx gas as an emision gases that was caused by vehicle will create that air quality degradation in urban area. Air quality mapping was needed as a based map to solved on air quality problem in urban area. The aim of this research are mapping of air quality in Surakarta Municipality and to select the cartographic symbols which optimum to represent of air quality data especially Cox for more readable and analysis. Data collecting based on field survey in some observation point that derived purposively on several roads and dense traffict. Field data plotting on the map are used in some symbols such as pie-graph, bar-graph, and text. The mentioned symbols are usual in cartography to represent of point symbol. The result of this research is distribution map of COx concentration in Surakarta Municipality. The road which has high COx concentration are cross jucntion in downtown (west side of Pasar Klewer), cross junction of Yos Sudarso street, Slamet Riyadi Street, and cross junction of Hay Lay (Wates). The used of pie-graph and bar-graph symbols produce more interesting map visually, but unfortunately the symbols cover up the information in their based map. The used of text symbol is more easy to handle for lay out, so the background object in based map is uncovere, but visually the map is not interesting.
The Hierarchy of Earthquake and Tsunami: The Cases of Aceh, Nias, Bantul, Pangandaran, and Sunda Staits
Authors: Hardjono Imam
Published: January 2017

Indonesia is vulnerable to earthquake and tsunami disaster because it is located in the fracture zone between the continental and oceanic lithospheres, running from the west of Sumatera, though the south of Java, NTB, Sulawesi to Papua. In the theoretical framework of Indonesian tectonic lithosphere, this zone is known as Sula-spuur. The frequent earthquake and tsunamis in Indonesia justify the theory that the earth will always seeks for dynamic self-balance through oceanic basin as well as continental basement expansions. Based on the tectonic lithosphere analysis, the anatomy of earthquake and tsunami disaster in Java falls into two different paths. The first is northwestward path in Western Java following the Semangko fault trend, from Pangandaran/Cilacap through Kadipaten, Subang to Jakarta. The other is the northeastward path in Central Java and East Java running from Bantul through Prambanan, Klaten to Rembang. The two hats correspond to the seventeen-kilometre-deep-underground fracture involving basement rocks resulted from the area shifting evolution during the limestone age prior to the existence of limestone in Indonesia. Based on the evidences found in Bantul- Klaten earthquake, the question necessary to raise is whether similar earthquake may happen in Jakarta.
Changes of Groundwater Quality in the Sorrounding Pollution Sources Due to Earthquake Dissaster
Authors: Sudarmadji Sudarmadji
Published: January 2017

Groundwater is the main domestic water supply of the population of the Yogyakarta Special Region, both in the urban and as well as in the rural area due to its quantity and quality advantages. The rapid population growth has caused an increase of groundwater demand, consequently it is facing some problems to the sustainability of groundwater supply. Lowering of groundwater level has been observed in some places, as well as the degradation of groundwater quality. Earthquake which stroke Yogyakarta on 27 May 2006, damaged buildings and other infrastructures in the area, including roads and bridges. It might also damage the underground structures such as septic tanks, and pipes underneath the earth surface. It might cause cracking of the geologic structures. Furthermore, the damage of underneath infrastructures might create groundwater quality changes in the area. Some complains of local community on lowering and increasing groundwater level and groundwater quality changes were noted. Field observation and investigation were conducted, including collection of groundwater samples close to (the) pollution sources. Laboratory analyses indicated that some parameters increased to exceed the drinking water quality standards. The high content of Coli form bacteria possibly was caused by contamination of nearby septic tanks or other pollution sources to the observed groundwater in the dug well.

There are three objectives of this research. First, to build the model of groundwater usage and conservation in the research area. Second, to identify the behaviour of model in various usages and conservations. Third, to formulate the policy of groundwater resources management that suitable with the region caracteristic. As a result, show that the programme Powersim 2.5c can be used dan applied in hydrologis, especially in building groundwater conservation model. The conservation model that significantly suitable are to decrease the usage of water in domestic and industrial sector. Relationship by the third objectives, the some policies that can be carried out to conservations, namely decreasing water usage, restricting industrial growth, restricting settlement growth (especially in recharge area) and increasing the capacity of PDAM production.

Published: January 2017

Landslide Hazard Zonationin South Sulawesi. Landslides are natural disasters that can cause substantial loss in the form of life and properties. Therefore, it is necessary to inventory landslide-vulnerable areas. A weighted summation model (Dibyosaputro, 1998) was applied to determine the landslide-vulnerable areas in the Geographic Information Systems (GIS). Factors that trigger the landslides are geology (rock properties, stratigraphy, structural geology, weathering level and earthquake), climate (rainfall), soil (solum thickness), topography (slope), vegetation (vegetation density) and human (land use); Siagian & Sugalan (in Sutikno, 1991) in combination with Dibyosaputro (1998). There are five classes of landslide vulnerability i.e. invulnerable, fairly vulnerable, quite vulnerable, vulnerable, and very vulnerable. In general, South Sulawesi is quite vulnerable to landslides, but there are three regencies very vulnerable for landslides; Luwu, Northern Luwu and Northern Toraja.Keyword : landslide, South Sulawesi.

Urbanization and Slum Residential Area in Cities: a Theoretical Review
Authors: Musiyam Muhammad
Published: January 2017

This paper aims to explain the inter relationship between urbanization and slum and squatter settlement phenomena in urban areas, focusing on two cases in Jakarta and Yogyakarta. Marginality theory and dependence theory are to explain the two phenomena above, because these theories have different assumption and different explanations about slum areas. Thus, the solutions offered are different too. The result of Tadjuddin and Taylor research into the slum and squatter settlement in Yogyakarta and Jakarta suggest that the phenomena of the slum settlement in this cities could not be explained by a single theory, either marginality theory or dependence theory.

Published: January 2017

Geomorphology as a part of earth sciences has a already known  for along time, however the development and application is relatively slow, especially in Indonesia. There is a tendency that the concept as well as the application of geomprphology will increase rapidly. The aims of this paper are to discuss the concept of geomorphology. The role of geomorphology in the physical geography studies and its application research activities. Geomorphology deal with land form as  subject of study and stressed on relief, processes, materials (lithology and its structure), and chronology has important role in the physical geography. Geomorphology be able to support of other sciences related to physical environment such as geology, pedology, hydrology, and archaelogy. In the practical application, geomorphology can be used in engineering purposed and regional development planning. In the research activities geomorphology can be used as basic frame work to determine sample areas, and also can be used as frame work to land resources evaluation with land form unit as land mapping unit or evaluation unit.
