UPN “Veteran” Yogyakarta’s Land Asset Area Planning in Semanu Gunung Kidul, Yogyakarta

Land is an asset in today’s era of development. A patch of land’s management must be planned so that its utilization can be done proportionally and professionally. The Special Region of Yogyakarta, namely Gunung Kidul Regency, has yet to have a reliable base map with high accuracy for each patch of land within its area, which results in the hampering of land use due to the lack of spatial information available. The lack of clear status and spatial information is felt by UPN “Veteran” Yogyakarta that has several patches of land in Gunung Kidul Regency, namely Kuwon Kidul, Pacarejo, Semanu, Gunung Kidul Regency. This research will create a base map scaled to 1:500 accompanied with information about height differences of said area and a recommended planning area considering three different aspects: geology, environment, and agriculture. The creation of a topographic map is useful for construction planning that will be conducted in the area. During this research, the topographic measurement and data processing were done in 11 days on field. The topographic measurement and data processing were conducted through five stages: initial survey, GNSS measurement, detail measurement, and data processing using software to produce a topographic map. The map result and measurement on field using Total Station showed that UPN “Veteran” Yogyakarta does not have a level surface and has good data density.

AN INVESTIGATION OF THE ASPECTS THAT AFFECT THE QUALITY OF REVITALIZED PUBLIC SPACES : With special reference to the city of Colombo, Sri Lanka

Public spaces are the places where all people can come together and spend their time without any restriction and it can be defined as the “City Living Room”. Therefore, these spaces can foster social cohesion, reduce psychological stress and provide physical activities. Public spaces have unique historic and architectural values and such places can be used to enhance the place making character of the area. Planning agencies often use revitalization, restoration, regeneration, refurbishment or redevelopment as Placemaking tools which can improve the quality of such public spaces in a city. It is often acknowledged that “revitalization” can be identified as one of the viable alternatives instead of demolition of historical buildings. “Revitalization” and “Adaptive re-use” can be identified as the tools for creating public spaces which are livable, accessible and convivial places for all. The previous studies have researched on the aspects an essential method to make places functional, attractive and convivial spaces. Although researchers studied the general functional aspects of revitalized public spaces, a few studies have focused on the quality and the barriers for such revitalized public spaces. This study attempts to fill this research knowledge gap and investigates what are the barriers and areas that need to be improved in the revitalization process within the Sri Lankan context by using three case studies in Colombo. As our framework of this study, we used access & linkages, comfort & image, uses & activities to assess the quality of revitalized places. This study further found that barriers associated with the process of revitalization are regulatory, social barriers, and technical barriers.

Causes of Landslide and its Socio-economic Effects: a study on Chattogram City and Surrounding Areas, Bangladesh

Landslide is a regular hazard in Bangladesh especially in Chattogram, the South-Eastern part of the Country. In 2007 and 2008 there happened two massive landslides in Chattogram. As a result, a huge number of people (130 and 11 respectively) died with heavy loss of properties affecting thousands of people in the region. Most of the landslides happened after torrential rain. Combined effect of rainfall and hill cutting induced slope instability adding Earthquake-triggered landslide in Chattogram. Some influential people are involved in hill cutting and developing hilly settlements in Chattogram. In some places, Government and non-Government authorities are developing settlements by razing hills there. A detailed area planning, landslide vulnerability zoning, landslide database development, geophysical analysis, and strictly implementation of Government’s existing rules are recommended to ensure avoiding further tragedy in Chattogram like 2007 and 2008.

Assessment of Influence of Residential Area Planning Structure on Air Quality Using Numerical Modeling

Numerical study of the aeration of a new urban microdistrict located along a highway in Novosibirsk, Russia, was performed. The main goal of the paper was to assess whether the architectural and planning structure of the new microdistrict is optimal in terms of aeration and air quality. A scenario of particulate matter (PM10) transfer in the vicinity of the microdistrict is reproduced. Numerical modeling is performed for the prevailing wind direction. 3D numerical simulation was carried out using the Revit software to build the CAD model of the residential area and the ANSYS software was used to perform a computational experiment. Based on the calculations, numerical data were obtained on the wind speed and on PM10 concentration fields in the residential area. Favorable and unfavorable zones of the microdistrict in terms of high concentrations of PM10 at the pedestrian zones were described.

Prinsip Perencanaan dan Kriteria Pengendalian Pengembangan Fasilitas Rest-Area pada Jalan Tol di Indonesia

Stopovers and relaxing facilities are important in intercity travel on toll roads. Long distances travel times in toll roads increase the supply and demand of these facilities in Indonesia. Not only the needs for refueling and resting, but also new support facilities demanded in rest area are often found, such as shopping, restaurant, worship place, and others. This phenomenon has attracted many investors to establish rest area with those complex facilities in term of business profit. To prevent negative impact of development and to protect main function of toll roads, this paper will discuss the planning and development control principles of rest areas located on toll roads in Indonesia. Analysis of components and criteria for rest areas on toll roads are generated by analyzing problems occurred. Site location, site area, accessibility, and main facilities specification are absolute factors, while zoning, circulation, road signage, and site utilities are conditional factors. The planning principles is to guarantee safety, security, and convenience of all activities in and around rest area and toll road. This research describes several criteria and components that should be controlled in order to achieve rest area planning principles that determined by qualitative methods.
