Abstract

Togean the islands are cluster of the small islands located in the district of Tojo Una-una and the very excited tourist attraction in Central Sulawesi Province. Some of the cluster of the islands is the settled place Bajo communities who occupied the coastal areas and the small islands. The islands are formed from the volcanic activity with the fertile plants as well surrounded by the rocks formations. Piles of the rocks to forms and functions as a place to living. Togean the islands has an area of ±362,000 ha and has been designated as one of the Marine National Park in the Indonesia. Case study research approah used with multiple cases, naturalistic quantitative data collection with analysis techniques in exploration.The islands in the islands Togean as a shelter the coastal communities particularly in the settlements on the islands of Enam/Enau (district Togean) and the island Kabalutan (district Walea the island). The two these islands setting show a very specifically lived spaces because it is strongly influenced by of nature physical factors, socio-economic conditions, and the local wisdom there. The development of the settlement spaces setting formal due to : (a) the limited land areas as a dwelling allocation, (b) presense of land potential that can be developed to support the economic life and the preservation of natural environment, and (c) the environmental suistainability of its settlement that a unique and specific. Keywords : Setting Space, Housing, Development Settlement

Abstract

Earthquake, tsunami and volcanic eruption are some of the various disasters that frequently hit in Indonesia. These disasters impact damage from small to large. These disasters also have a major impact on the balance of community lifes who are victims. Various efforts of reconstruction, rehabilitation and reconstruction are undertaken by governments, communities and various stakeholders. To succeed as expected, these efforts should be based an a spatial plan which is suitable and comprehensive. The spatial planning in disaster prone areas is indispensable in dealing with disasters before, during and after a disaster. Formulation and implementation of spatial plans are turned to face many problems such as limited and the loss of data due to disasters, as well as social and cultural conditions in disaster prone areas. To streamline the implementation of spatial plans and land use control need zoning regulation as a land use control instrument. Therefore, it is necessary to study the role of zoning regulation in the utilization of space and rebuilding in disaster areas prone.This study used a descriptive approach with literature sources. The results show that: (1) The Making of spatial plan on the basis of disaster mitigation in disaster prone areas is indispensable in dealing with disasters, before, during and after a disaster and should be complemented with zoning regulations, (2) The making of spatial plan and zoning regulations in the region after the disaster requires a special approach by modifying the normal procedure, and (3) zoning regulation as a land use control instrument control instrument guides the implementation of various activities related to disaster mitigation and need to be adjusted to the social, economic, cultural and characteristics of each disaster prone areas.Keywords : spatial plan, zoning regulation, disaster prone areas, disaster mitigation.

Abstract

The dynamic of land utilization is related to changes of land function. In this contect, the morphological study is impemented to uncover the changes in land functions in Kampung Luar Batang, Nort Jakarta, Indonesia. Kampung Luar Batang is a historical Kampung which was estabished by VOC in Batavia under the influence of existence of a Moslem missionary, Al-Habib Husein bin Abubakar Allaydrus, and accelerated by the its strategic geographical location close to urban economic centers, Historically, Luar Batang has been a place for laborers' settlement, VOC defense port, port of transit for migrants, pilgrimage center and rental dwelling that is surrounded by illegal housing. Each function was not chronologically appeared, but developed in multi-layered manner.In fact the historical meanings of Luar Batang were not obtained through in depth literature study, since the availability of references about the kampung is very limited. This study is an effort to uncover the physical elements of the kampung from historical perspective, based on the maps documentatin and empirical study. The graphical abstraction model presented at this paper is an attempt to clarify the dynamic of land utilization.Keywords : Morphology, Kampung bersejarah, Luar Batang.

Abstract

In this research, we exctract and identify MRI brain images based on eigbrain image.  MRI barain images are used to be input for feature exctraction and identitication. Feature exctraction is done by using the eigbrain image. For all reference image, we find image mean and eigbrain image, and the results are stored. If there is test image, we will find the nearest distance of eigenbrain between test image and reference images. The feature extraction is used to identify the image is whether the normal brain image or the brain image with tumor.The results show that the method successfully classifies MRI images into tree clusters: normal,  glioma, and metastase. The input test images can be identified accurately 100% for image  sizes from 256 x 256 pixels to 64 x 64 pixels.Keywords : feature extraction, image identification, MRI medical image, eigenbrain image.

Abstract

     The aims of the experiments are to characterize of the cooling tower by using the bank of the pipes as the fluid distributor. The cooling tower is constructed by rectangle of glasses which it has 9 cm x 9 cm in cross section and 100 cm in height. The fluid distributors are constructed by pipes in 5/8 inch of nominal diameter. There were five types of the packing namely the fluid distributor without baffle, fluid distributor with one baffle, the fuid distributor with two baffles, the fluid distributor with there baffles and the fluid distributor with four baffles.     The experiment have been done by flowing the hot water from the top of cooling tower through the fuid distributor, on the other hand, the air cooler is flown above through the fluid distributor opposite to the water flow direction. This process makes the exchanging of the heat between air and water on the fluid distributor. The variables varied in this experiments are the inlet water temperature, Twi (45, 50, 55 and 60 °C), the height of fluid distributor, Z (30.5, 61 and 91.5 mm), the ratio of water/air mass flow, mw/ma (3.624, 5.888 and 7.700) and the number of baffle (without baffle,  one baffle, two baffles, three baffles and four baffles).     The experimental results show that in the ratio of water/air mass flow rate which is lower, the increasing of the numbers baffle cause the decreasing of characteristic. Mean while, in the ratio of water/air mass flow rate which is higer, the increasing of the numbers of baffle cause the increasing of the characteristic. The cooling tower without the fluid distributor has the average characteristic is 13.4% and the average effectiveness is 16.2%. For the cooling tower with the fluid distributor has the average characteristic is 31.5% and the average effectiveness is 25.0%. Keywords : Cooing tower,  characteristic, fluid distributor.
