Abstract

Klaten Regency is a regency that owning very strategic situation, that is lay between 3 (three ) metropolis (Jogjakarta, Surakarta, and Semarang). This Regency is having immeasurable properties, there are agriculture area, tourism, mining, and so on. This condition is obliging that this regency have to make an inventarisation of their properties to make a profile so thisregency can make a good decision to their region especially to their peoples. This research use secondary data analisys that collected from region statistics and by collecting data from many related institution and than it can gives some resource balance of this sub-province. Topographic condition of Klaten Regency predominated with flat and landuse which is rice field areal still majority, designate that this area is compatible used for agriculture. This condition is proved with big paddy supply which reach 300 ton per year while other agriculture product just only about tens of thousand ton. Agriculture sector is a potential sector to buils but the condition is worsed by the degradation of rice field areal with 26 hectare per year and also the increasing of the amount of resident every year that is proving the high requirement of land. Besides agriculture, this sub-province is also supported with mine and tourism sector. Mining sector are stone, clay, and sand are caused by the location of this area is in volcanic hill side. Tourism sector also contribute big Region Original Income to this Regency which progressively mount every year. By 3 (three) tourism object type, this sector can contribute Region Original Income equal to 773.674.000 rupiahs and supported with hotel facility, restaurant, and accessibility which mounting every year. However, amount of terminal which in this time there is not yet supported the demand.This Regency also experience of the increasing of economic sector, that is the financial that is the amount of Foreign Capital Proyect and Nation Capital Proyect, Region Original Income , and Brotto Regional Domestic Product that designating the increasing of people level live.

Abstract

Sedimentologi adalah cabang dari ilmu geologi yang khusus yang mempelajan batuan sedimen, sifat-sifat fisisnya, tempatnya dalam kerangka geologi, dan proses pembentukannya, terutama cara dan lingkungan pengendapannya. Salah satu dari mekanisme sedimentasi, adalah sedimentasi sistem arus turbid (arus pekat), yaitu material sedimen yang beronggok pada suatu lereng samudra, kemudian secara tiba-tiba terkena hentakan dan meluncur dengan kecepatan tinggi bercampur air berupa suatu aliran padat ("density current"). Pada mekanisme ini, partikel-partikel sedimen bergerak tanpa benturan/seretan air, tetapi "energi potensial" dirubah menjadi "energi kinetis". Pengendapan terjadi setelah energi kinetis habis, misalnya pada tempat yang datar atau pada lekukan-lekukan. Arus turbid ini terjadi di laut dan merupakan mekanisme penting dalam mentrasfer material sedimen dari daerah bathyal dan abisal ke daerah hadal. Formasi Halang, yang terdiri dari perselingan antara lapisan-lapisan batu pasir dan batu lempung, berumur Miosen Awal, Miosen Tengah, dan diketemukan di daerah Ciawigebang, Kabupaien Kuningan, Jawa Barat, merupakan salah satu contoh endapan hasil sedimentasi oleh arus turbid.

Abstract

This research was carried out in the Coastal Area of North Java, District Brebes, Central Java. It aims at finding the mechanism of factor that influence the dinamics of coastal geomorphological process and the distribution of the dynamics of the geomorphological process. The primary data consist of coastal forms, coastal building/ human activity, sea current, and distribution of the coastal sediment were collected by field observation and measurement. The secondary data consists of the climate, wave, bathimetry, tide, and regional sea current were collected from the related institutions. The technique of data analysis includes Beaufort Scale is employed to find out the characteristics of wind and wave. The laboratory analysis is used to find out the distribution of the coastal sediment. The discriptive analysis is used to desribe the sea current, tide, bathimetry, and human activity.The outcome of this research indicates that Mousoon wind making waves and longshore current can transport sediments which come from Cisanggarung and Pemali river. The small range tide (95 cm), the fine coastal sediment (clay), the shallow bathimetry (0 – 5 m), and human activity (building coastal pand) to provoke the dynamical changing of coasline. The dynamics of the geomorphologycal process from 1944 to 1964 indicates that the coastal area progressed dynamicly; from 1964 – 1997 indicates that the some coastlines (location 1, 4, 5, and 6) progressed, some coastline (location 2, 3, 7, and 8) regressed, and some coastlines (between location 3 to 4 and location 6 to 7) were relativelly stable.

Abstract

Borobudur is a famous tourism destination which is listed as a World Heritage Site listed in 1991. Recently the condition of the temple is threatened with many problems related to tourist behaviors, overcrowded vendors and traders, as well as managerial issues. This research was carried out with literature study, field observation, peer discussion and seminar. Reflecting the history, this research tried to explain the rise and fall of civilization. This research tried to explain Borobudur as magnet for tourism destination and tourism as locomotive for community and regional development. There are five reasons why glory of civilization can fall even dramatically: (1) horizontal conflicts among social groups; (2) intrigue and struggle for power among elite leaders; (3) expansion and occupation from foreign power; (4) environmental degradation; and (5) disasters like volcanic eruption, earthquake and tsunami. Borobudur has many enigmas, when and why the fall of its civilization. It is not easy to explain these enigmas. The results of this research are: (1) it is possible combination of causes the fall of Borobudur civilization, but the most possible was volcanic eruptions of Merapi. (2) Borobudur has problems related to the tourist number who disturb the stone relief and statues when they climb up the temple (3) Tourists disappointed to lack of hospitality and low quality of services provided by the management as well as the vendors and traders. (4) The problems of conservation related to environmental changes. Among others, prime recommendation is “Rethinking Borobudur” to get new alternative and strategy to manage this world heritage.

Abstract

Settlement means a place (spatial) or an area where population conentrated on and live in together to make use of the environment to survive direct and develop their living. Pattern and distribution of the settlement constitute a closed connection. The settlement distribution deliberates the fact of where the settlement exists or is not obtainable in an area; while the settlement pattern constitutes a distribution characteristic which has much more connection with the effect of the economical historical and cultural factors. There are some measurement methods of the distribution pattern i.e with the neighborhood analysis formula (t) where if t = 0 it means the settlement pattern conentrates, t = 1 shows the random settlement pattern (uneven distribution), while if t = 2,15 shows the uniform (homogeneous) settelement pattern. The second method is the Demangoens Index (C) which only considers the total of the population, besides C score of the concentration, random, and uniform of the settlement pattern are not detected. Another measurement method is score per “grid square”. The method of R scale is also applicable in the measurement, in which R score is concerned with 0 – 2,1491; if score of R = 0,7 it shows that the settlement pattern would be in group; R = 0,7 – 1,4 means an uneven distribution and R = 1,4 – 2,1491 shows the evenly distribution of the settlement pattern.

Abstract

Medium resolution satellite data such as Landsat is very potential for mixed pixel (mixel) to occur. Indonesian land use diverse especially urban areas makes high potential mixel in the first Landsat pixel size of 30 meters x 30 meters on the actual condition. Aircraft multispectral aerial photo data LAPAN Surveillance Aircraft (LSA) with a spatial resolution reached 58 cm can display objects in more detail in these sizes. The purpose of this research is to study mixel on Landsat data with multispectral data LSA as a complement Landsat data. The method proposed in this study is a visual interpretation with GEOBIA method for classification of land cover, and then test the validity of the sample to be used in research, and the use of such vegetation index NDVI to see the connection between vegetation index data of vegetation index LSA with Landsat data. The results showed that the regression equation obtained by regression between NDVI of Landsat data and NDVI of  LSA with a significance of less than 0.05 is y = 0.732x - 0102 with a value of R2 = 0.887. Through these results we can conclude that the NDVI values on both the data related to one another.

Abstract

In recent years, heavy rainfall leading to floods, landslides and debris-flow hazards have had increasing impacts on communities in Japan, because of climate change and structural immobilism in a changing and ageing society. Decreasing rural population lowers the human vulnerability in mountains, but hazards can still leave the mountain to the plains and sea, potentially carrying drifted-wood. The aim of the paper is to measure the distribution of wood-debris deposits created by the 2017 Asakura disaster and to rethink the distribution and spatial extension of associated disaster-risk zoning. For this purpose, the authors: (1) digitized and measured the distribution of drifted-wood, (2) statistically analyzed its distribution and (3) calculated the potential impact force of individual drifted timber as a minimal value. The results have shown that there is a shortening of the wood debris as they travel downstream and that the geomorphology has an important control over deposition zones. The result of momentum calculation for different stems’ length show spatially differentiated hazard-zones, which limit different disaster-risk potentials. From the present finding, we can state that we (1) need to develop separate strategies for sediments and wood debris (2) and for wood hazards, zonations can be generated depending on the location and the size of the deposited trees that differs spatially in a watershed.

Abstract

Not only does poverty in developing country face decline of relative imbalance, but they face the increasing of absolute poverly as well. One of the characteristic of developing country is signed by growth population rapidly. Economic development prospect doesn’t apart from ratio between quantity of population and land suitability. The limitedness of land that be done by farmer cause the decline of agriculture production, besides, the growth of wotk opportunity increase, the employment is restricted. Some main  problems that must be faced by now are; the distribution of income, work opportunity, man power quality, and many alternative approach to be sub mitted to reach the economic growth by distribution.
