Adi Sutjipto International Airport is the airport currently operated in Special Region of Yogyakarta (SRY), located near the city centre area. SRY needs to construct a new airport due to the increase in air passengers. The proposed airport, named New Yogyakarta International Airport (NYIA) is located in the undeveloped area, away from the city centre. This study is aimed to investigate the impact of airport relocation to the road network and to assess several developments of transportation infrastructures to the new airport.  The analysis was conducted by developing a transport network model using PTV Visum. The secondary data collected from the local government to develop the transport network model, including the development of origin-destination matrices and forecasting purpose.  The scenarios of road infrastructures development and new rail service to the airport in 2025 are then modelled. The results showed that the road infrastructure developed can reduce the number of congested main roads from 9.47% into 5.94%. Rail service to the airport is effective to decrease the traffic congestion at two NYIA roads access and able to increase their average speed from 49.45 and 44.29 km/h into 66.45 and 62.66 km/h.

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.

Continuous, automatic measurements of road traffic volume allow the obtaining of information on daily, weekly or seasonal fluctuations in road traffic volume. They are the basis for calculating the annual average daily traffic volume, obtaining information about the relevant traffic volume, or calculating indicators for converting traffic volume from short-term measurements to average daily traffic volume. The covid-19 pandemic has contributed to extensive social and economic anomalies worldwide. In addition to the health consequences, the impact on travel behavior on the transport network was also sudden, extensive, and unpredictable. Changes in the transport behavior resulted in different values of traffic volume on the road and street network than before. The article presents road traffic volume analysis in the city before and during the restrictions related to covid-19. Selected traffic characteristics were compared for 2019 and 2020. This analysis made it possible to characterize the daily, weekly and annual variability of traffic volume in 2019 and 2020. Moreover, the article attempts to estimate daily traffic patterns at particular stages of the pandemic. These types of patterns were also constructed for the weeks in 2019 corresponding to these stages of the pandemic. Daily traffic volume distributions in 2020 were compared with the corresponding ones in 2019. The obtained results may be useful in terms of planning operational and strategic activities in the field of traffic management in the city and management in subsequent stages of a pandemic or subsequent pandemics.

Post Disaster

The purpose of this study is to identify and describe the impact and behavior of the community on post-disaster economic conditions in the city of Palu and to know the local government's public policies in handling these cases. Using qualitative methods with a case study approach, literature study, and secondary data processing from various social elements. In addition, data collection was carried out by interviewing informants who felt the direct impact of the earthquake, tsunami and liquefaction in Palu, Sigi and Donggala. The results showed that the post-disaster impact felt by the people of Palu City was generally in the "severe" classification. The socio-economic conditions of the people of Palu include several aspects, ranging from the geographical conditions that are in disaster-prone zones, to the extremely poor health conditions after the disaster. The conclusion of this research shows that the escalation of natural disasters in the city of Palu is considered quite large because it consists of three types of disasters, namely the Earthquake, Tsunami and Liquifation in the same time period. Palu City is the capital of the Province as well as the economic and administrative center of Central Sulawesi Province. Damage to warehousing infrastructure coupled with massive looting from unscrupulous people in logistics supply warehouses resulted in goods that were supposed to be distributed both to the city and the district finally unable to be implemented.Tujuan penelitian ini yaitu mengidentifikasi dan mendeskripsikan evaluasi dampak dan perilaku masyarakat terhadap kondisi perekonomian pasca bencana di kota Palu dan mengetahui kebijakan publik pemerintah setempat dalam menangani kasus tersebut. Menggunakan metode kualitatif dengan pendekatan  studi kasus, studi literature, dan pengolahan data sekunder dari berbagai elemen sosial. Selain itu pengambilan data dilakukan dengan cara wawacara kepada narasumber yang merasakan dampak langsung dari bencana gempa,tsunami dan likuifaksi di Palu,Sigi dan Donggala. Hasil penelitian memperlihatkan bahwa dampak pasca bencana yang dirasakan oleh masyarakat Kota Palu secara umum berada pada klasifikasi “berat”. Kondisi sosial ekonomi masyarakat kota Palu meliputi beberapa aspek, mulai dari kondisi geografis yang berada pada zona rawan bencana, kondisi kesehatan sangat memprihatinkan pasca bencana. Kesimpulan penelitain ini menujukkan bahwa eskalasi bencana alam kota Palu dinilai cukup besar karena terdiri dari tiga macam bencana yaitu Gempa Bumi, Tsunami dan Liquifasi dalam kurun waktu sama. Kota Palu merupakan ibukota Provinsi sekaligus sebagai pusat ekonomi dan pemerintahan Provinsi Sulawesi Tengah. Rusaknya infrakstruktur pergudangan ditambah dengan adanya penjarahan yang massiv dari oknum masyarakat pada gudang-gudang suplai logistik mengakibatkan barang yang semestinya didistribusikan baik ke kota ataupun ke kabupaten akhirnya tidak dapat dilaksanakan.

Several works have investigated the impact of urbanisation on carabid activity density using urban-rural gradients. Such works compared activity density recorded from green spaces located in different parts of a city and assigned to categories of increasing urban intensity, which poses two problems: (1) since the gradient is divided into categories, it is impossible to model continuous variations in biotic responses, and (2) sites representative of different urbanisation levels are not true segments of the same ecological continuum. To surpass these problems, we modelled variations in carabid activity density along an urban-rural transect within a single green space extending from the city centre of Rome to rural environments. Carabids were sampled by pitfall traps from sites distributed along the entire gradient. We used breakpoint regressions to model how (1) carabid activity density, (2) carabids/beetles ratio, (3) carabids/insects ratio and (3) carabids/arthropods ratio varied along the gradient. As already observed for various organisms in urban environments, we found that activity density of carabids and their contribution to the abundance of beetles, insects and arthropods, peaked in the middle of the gradient. This supports the intermediate disturbance hypothesis, according to which moderate urbanisation may favour diversity by increasing habitat heterogeneity.

In Tanah Grogot district, precisely on the KM 6 road which is the city boundary roads of Tanah Grogot City-Lolo Kuaro it has an important role as the only access for road users. Because at the side of the roads does not have a drainage channel, resulting in water overflowing and the seepage flowed on the surface, causing a landslide. The length of the landslides is 50 meters, with a width of 5.5 meters and the highest height is 9.6 meters. The result of this landslide is very disturbing for the road users. The delivery of goods and services can not be accommodated properly. Therefore, it is expected that this path must be handled properly, so the road can be functioning again safely and comfortably. How to handle this problem is by making a design of retaining walls construction which is safe in form of sheet pile.The planning for this anchored sheet pile begins with analyzing the secondary data in form of data sondir, laboratory data, and topographic measurement data. This then followed by the calculation of the forces acting on the sheet pile, the calculation of moments in the sheet pile, the calculation of the carrying capacity of the pile on the anchor, capacity calculations for the mast against a lateral load, and the slope stability analysis using GeoStudio2007 application. After that designing the sheet pile construction, tierod, the pile, planning the budget, and makes the Detail Engineering Design (DED).From the planning, the profile of concrete sheet pile obtained is CCSP W-500-A-1000 with a total length of the sheet pile is 12.2 meters. On tierod using dimensions of 6.32 m long with a diameter of 5 cm. On the pile is using a steel pipe with a diameter of 40 cm which penetrated into 10 m depth. For the stability of the slope with the reinforcement of piles obtained SF = 5.5> 1.25, which can be said as safe.Keywords:  designing sheet pile, anchored sheet pile, steel pipe piles.

ObjectivesTo compare the proportions of emergency department (ED) attendances following self-harm that result in admission between hospitals, examine whether differences are explained by severity of harm and examine the impact on spatial variation in self-harm rates of using ED attendance data versus admissions data.SettingA dataset of ED attendances and admissions with self-harm to four hospitals in South East London, 2009–2016 was created using linked electronic patient record data and administrative Hospital Episode Statistics.DesignProportions admitted following ED attendance and length of stay were compared. Variation and spatial patterning of age and sex standardised, spatially smoothed, self-harm rates by small area using attendance and admission data were compared and the association with distance travelled to hospital tested.ResultsThere were 20 750 ED attendances with self-harm, 7614 (37%) resulted in admission. Proportion admitted varied substantially between hospitals with a risk ratio of 2.45 (95% CI 2.30 to 2.61) comparing most and least likely to admit. This was not altered by adjustment for patient demographics, deprivation and type of self-harm. Hospitals which admitted more had a higher proportion of admissions lasting less than 24 hours (54% of all admissions at highest admitting hospital vs 35% at lowest). A previously demonstrated pattern of lower rates of self-harm admission closer to the city centre was reduced when ED attendance rates were used to represent self-harm. This was not altered when distance travelled to hospital was adjusted for.ConclusionsHospitals vary substantially in likelihood of admission after ED presentation with self-harm and this is likely due to the differences in hospital practices rather than in the patient population or severity of self-harm seen. Public health policy that directs resources based on self-harm admissions data could exacerbate existing health inequalities in inner-city areas where these data may underestimate rates relative to other areas.

Changes in land use, which accompany the development of towns, generate a transitional zone on the border between areas of urban and rural use, which—due to its complex (unspecified, fuzzy) land use—cannot be identified either as a rural or an urban area. In order to prevent the unplanned development, it should go according to plan, in line with the spatial order principles, making a coherent whole, taking into account all functional, socio-economic, cultural, as well as aesthetic factors and requirements. This paper describes studies and analyses of the fuzzy set theory applicability in studies of land use in areas around towns. The main aim of the study was to present the methodology, which employs fuzzy logic to identify and locate a transitional zone between rural and urban areas. This study dealt with the transitional zone at the junction of the urban and rural area and its parameters, which affect the type of land use. The attributes of the transitional zone were defined based on an analysis of current land use methods in areas under direct urbanisation pressure. The study was conducted in the city of Olsztyn (Poland) and on its outskirts, directly exposed to the impact of the developing city, with an area of 202.4 km2, within an 8-km radius of the city centre. The study determined the impact of individual forms of land use on the development of urban or rural use. The degree of each type of use—urban or rural—allowed for developing a fuzzy town and country model, identifying the urban investment border and its spatial dispersion, as well as identifying and locating the transitional zone between urban and rural areas. Moreover, land cover models based on the Corine land cover (CLC) data as well as high-resolution layers (HRL) impervious and canopy data were developed. The borders of urban investment determined on the basis of the fuzzy set theory assumptions, CLC, and HRL data were also identified and verified.
