Abstract

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.

Abstract

This study is carried out in Nusukan, Banjarsari, Surakarta. The problems that are related to economic crisis in Indonesia are the supply of contraception, the weakening of people purchasing power so they influence the realization of family planning program. The goals of the study are: to know the supply of contraception for poor household, to study the influence of the effect of economic crisis for the participant of family planning, to study the change of birth control and its effective strategy and to know the quality of family planning service. The data are collected using observation, and questionnaire. The study takes the area in which it has more productive couple, the percentage of poor families and the prosperous families I that belong to productive couple whose age 20 to 49 years old, at least they have two children, and participant of family planning or ever followed it. The result of the study shows that 82% respondents can get contraception easily before and at economic crisis. It is one of the important factors, for which the participant of family planning is still high. Although the economic crisis influences the price of contraception and family Income, it does not affect the participant of family planning. 87% respondents participate actively the family planning. This shows that the people have realized the importance of family planning program. There is an impact of economic crisis for the change of the ways of birth control. 38% respondents have changed over their strategy from modern to traditional contraception and the contrary, and from modern contraception to the other one. Some of them are abstention. The level of the people adaptation is high enough. They use various ways to prevent of being pregnant. 92% respondents do not want to be pregnant. If it happens an unwanted pregnancy, 15% of the respondents will abort their pregnancy. This is the challenge for the officers and the government to supply safe and accurate contraception and to give clear explanation about the effect of abortion from healthy and religious aspect. The service of family planning by the government and private institution is good enough (81%). Respondents can get contraception (especially tablet) easily; cheap and free of charge, but the other ones such as spiral is more difficult because it is more expensive and limited.

Abstract

The purpose of this study was to determine the Erosion hazard, to look for conservation of bio - mechanical techniques are appropriate . Research methods with overlies topographic maps, soil maps, land use maps, to obtain a Land Unit Map. Determined soil physical properties (texture, structure, permeability) and chemical properties of soil (soil organic matter), slope, slope length, broad of land unit, crops factor and value conservation factors that have been there for Land Unit. Each land unit is determined the amount of land erosion and erosion hazard level. Erosion hazard level is determined based on soil erosion, and soil depth. Erosion hazzard level is used to determine the bio-mechanical conservation, according Hardjowigeno and Sukmana (1995). The results showed that the highest erosion hazard level with an area of 12.947 ha is classified weight (Land unit 15A), and the classification of an area of 14.665 ha is clssified moderately (Land unit 6A). Soil conservation is done in areas with highest erosion hazard level by making individual terraces and “kerandang” planted as a cover crops.

Abstract

This article is about development a regression equation to determine the perception of thermal comfort for pedestrians in the humid tropical climate. Methods used was field studies and questionnaires to 60 samples as respondents in Manado. Each of the respondents was asked to act as pedestrian but walked on a treadmill for 2 minutes 5 five times. They regrouped into two parts, one who walked under open-sky and another group was under the shade of trees. Measurements of climate variables include air temperature, air humidity, radiation temperature, land surface temperature and solar radiation. Measurements to the respondents were their height, weight and skin temperature. By using statistical approach it is obtained a regression equation "Y=- 6.1369 + 0.479 Adu + 0.1143 Ta + 0.0376 Trm + 0.2541 RH + 1.6793 clo". The equation was then validated by comparison with other equations of non-tropical humid climate case. It is found that the empirical regression equations of outdoor thermal comfort developed by means of field studies in a certain climatic conditions could not be applied for a wide range of climate.

Abstract

Ketidakmerataan penguasaan lahan merupakan sumber utama ketidakmerataan pendapatan. Satu hal yang tidak dapat diabaikan ialah masalah penguasaan lahan bukan pemilikan dapat pula menentukan pendapatan petani. Penguasaan lahan bukan milik sendiri misal lewat sewa atau penyakapan. Lahan yang dimiliki seseorang di pedesaan belum tentu digarap sendiri, pemilik lahan yang terlalu sempit ada kalanya menyewakan lahannya pada petani luas dan mereka cenderung menjual tenaganya sebagai buruh tani. Dengan demikian dimungkinkan terjadi penguasaan lahan yang timpang serta distribusi pendapatan menunjukkan hal yang sama.

Abstract

The objetive of this research were conducted in Kulon Progo Regency were to know how far utilization of farm technology (hand tracctor, tresher, benguk arver, and cassava rapier) will inreasing income farmer and works diversification on different topography and accesibility. The data included primary and secondary data. The primary data were collected from respondents by filling questionnaires, while the seondary data were collected from the governmental officer. Region samples are Lendah sub regency which low land plain area, Sentolo sub regency which hilly area, and Kalibawang  sub regency which mountain range area. Respondents sample was taken by snow ball sampling, who utilized of farm technology and they are 58 respondents from low land plain area, 38 respondents from hilly area, and 38 respondents from mountai range area. The data were processed by using computer, while hypothesis was tested by crosstab and hi quadrate to compare result of research in the three different topography areas. The result of the research shows that there are difference significant utilization of farm technology aording to the topography bakground. Hand tractors and tresher are much  utilized in the hilly areas, benguk carvers are much utilized in the low land plain areas, and cassava raspiers are much utilized in the mountain range areas. They aren’t difference signifiant the utilization of farm technology aording to accesibility. The low land plain areas and the hilly areas produce same activities, while the mountain range areas produce only four kind of same ativities. Diversification of works in the hilly areas absorbed a lot of manpower than those and the rest areas. Income generating from the utilization of farm technology in the hilly areas is more than that in the rest areas.

Abstract

The research was conducted at the Upper Bengawan Solo Catchment, which was categorized as critical catchment. The problems of flood and drought became the main issue, and need to be handled sooner, therefore it need hydrological modelling to coupe the problems. As we know that the role of rainfall as an input to the model is very significant parameter in generating output (discharge), then the objective of this research is to know the rainfall characteristics. The rainfall distribution in the research area can be known by doing the spatial analysis, especially using Kriging method. It does the rainfall mapping for a certain duration to describe the spatial rainfall distribution. It uses the rainfall data from 20 rainfall stations with 5 minutes interval recording. It does the inter-stations correlation analysis on the amount of rainfall and the distance of inter-stations. The significant level used in this study is 5%. The result shows the tendency that the more of the station number decreased, the smaller the rainfall correlation coefficient inter-stations are. It can be meant that the numbers of the rainfall stations in catchment area have optimum number of gauge. The coverage area for each station is 13 km2 when we use 5’s minute interval data. Most of the rainfall which have intensity 30 mm/hr occur at minute 20th to 125th. As much as 17.5% of these rainfall have randomly distribution. There is a significant relationship (R2=65.2%) between daily maximum rainfall and minimum values of inter-stations correlation coefficient Base on above results it is very important to consider that in chosing the size of catchment area for hydrological modeling it should be related with its rainfall chracteristics.
