Modeling Complexity of Urban Land use and Transportation In Semarang City
Authors: Widjonarko  , Maryono  , Fauzia  
Published: May 2021

Abstract
The development of urban areas will increase the travel demand of its population. Travel demand is often associated with the type of activity indicated by the type of land use. Travel demand can be predicted with developments in land use. The development of increasingly complex land uses will result in higher trip generation, so we need a model that can be used to estimate trip generation. The research objective is to understand the relationship between trip generation and travel attraction as a travel request with land use characteristics in the city of Semarang. The method used is spatial regression using variables Y (trip generation), X1 (housing area), X2 (trade area), X3 (industrial area), X4 (office area) and X5 (education area). All data uses spatial units in the kelurahan. Spatial regression results indicate that the movement in the city of Semarang is strongly influenced by housing activities, trade activities and offices. Industrial and educational activities make less significant contribution. The mathematical model of spatial regression of population movements in the city of Semarang can be denoted as follows Y = 626,41 + 28,69X1 + 0,06X2 + 5,49X3-18,84X4-10,71X5.

Abstract
Located in the heart of the so-called ‘paradise island’ Bali, a medium-sized city, Denpasar is facing unprecedented transformation. As the capital city of Bali Province, which is the highest contributor for tourism sectors in Indonesia, it has experienced rapid economic and population growth. Coupled with pressures from global forces in the tourism industry, Denpasar could perceive both negative impacts as well as challenges due to the urban transformation. This paper concerns how a city deals with the unprecedented urban transformation and globalisation, a city in the developing world such as Denpasar can survive and achieve some progress. It aims to document and assess, in particular, local government’s innovations and leadership in ensuring the sustainability of the city. It is a descriptive and exploratory, based on field works, interviews, FGDs, and the available secondary data. This paper has successfully explored that Denpasar has launched many innovations to deal with current problems and to ensure its sustainability. Aside from that, it argues that innovations and local leadership are keys for the city to be able to respond to an unprecedented urban transformation and a changing world, as the answer for lacking the empirical experiences of local context for advancing urban sustainability.
Urban Form Factors that Play Important Roles on UHI Spatial-Temporal Pattern: A Case Study of East Surabaya, Indonesia

Published: May 2021

Abstract
Urban Heat Island (UHI) has a negative effect on the local climate and ecological environment. On the other hand, urban form has an impact on the urban thermal environment. However, the relationship between UHI’s temporal spatial pattern and the urban form is still unclear. Our research explores the distribution patterns of UHI in East Surabaya based on surface temperature data calculations from Landsat imagery in 2001-2019 every 5 years. The results show that have been inconsistencies in the UHI pattern over the past 18 years and the most significant change occurred in 2016 and 2019. There is a difference in the intensity of UHI between built up area and non-built up area. Factors that are characteristic of urban form include urban green infrastructure, urban geometric and urban material with their respective variables. Using spatial regression OLS (Ordinary Least Square) variables that affect UHI include albedo type, sky view factor, building density, urban green space and urban water space. The mean building high variable has a negative correlation with UHI, this explains that the higher the building does not necessarily affect the increase in urban temperature. Our research can be a reference in formulating UHI adaptations.

Abstract
Malaysia is situated at Sunda plate that experience highly dynamic of earth’s crust with frequent earthquake and volcano activities. The effect of plate motion causing the static-based geodetic reference frame in Malaysia is no longer relevant to support the centimeter level of Global Positioning System (GPS) application. Therefore, an updated Sundaland plate motion model is necessary to cater to the effect thus preserving the reliability of the geodetic reference frame. This study aimed at determining regional plate motion of Sundaland in support of dynamic reference frame. The work involved in generating precise Position Errors Time Series (PETS) from GPS Continuous Operating Reference System (CORS) data in Malaysia and neighbouring country. The Coordinates Time Series (CTS) were then used to estimate velocity vector and the precision form the results depicted at -8.0429±3.0215mm, 3.873±3.288mm, and 0.913±7.775mm for component northing, easting and up, respectively. From the velocity vector, location of Euler pole of Sunda plate was found at latitude 5.8482 ° N and longitude -95.1017 ° E with estimated angular momentum of 0.201Ω/Myr± 0.0389. It can be expected that the result will be useful for maintaining the reliability of the reference frame in South East Malaysia.

Published: May 2021

Abstract
The eKadaster system depended solely on the use of coordinated cadastral database known as the National Digital Cadastral Database (NDCDB) with an expected accuracy of ±10cm. Till date, there is an approximately of 7.8 million land parcels and 21.9 million boundary markers in the NDCDB that covers the total area of 132,183 km2. However, the NDCDB accuracy of ±10cm is still not at a satisfactory acceptance level and the adjustment keeps continuing without carrying out verification to the data sources weakness of varying accuracy and input errors. Thus, the foremost important corrective is to ensure the adjustment input files to have the exact value of the sources by further divided the existing adjustment blocks into smaller blocks to verify the input data line by line. A well distributed cadastral control points and latest NDCDB accessibility are also extensively needed to plan and to strengthen the adjustment network. The comparison result of the randomly picked ground truthing points in the field has shown a significant impact on the displacement accuracy that meet the expected tolerance of ±10cm or better after the data input file is cleaned without input error. And to further strengthen the adjustment network in order to make NDCDB accuracy better, the current cadastral control points shall need to tie to a highest accuracy fundamental network.

Published: May 2021

Abstract
The emergence of low-cloud and low-visibility can affect air activities, and bring huge economic losses to airlines. Based on the aviation meteorological observation, forecast and airport alert of Pudong and Hongqiao airports, this paper analyses the meteorological service effect of a low-cloud and low-visibility weather process in Shanghai from January 27th to 28th, 2016. The results show that: (1) The absolute error between forecast and actual situation of Pudong and Hongqiao airport presents an obvious normal distribution and the forecast accuracy of Pudong is higher than that of Hongqiao. (2) For the airport with cloud ceiling of 30m∼60m and prevailing visibility of 600m∼800m, the alert of Pudong airport is more accurate and advanced, but for the airport with cloud height of less than 30m and prevailing visibility of 400m∼600m, the airport alert is quite different from the actual situation, and lacks lead time. (3) The alert of Hongqiao airport is accurate for the airport with visibility less than 800m from 03:30 to 10:30 on 28th, and the lead time is relatively high. However, it lacks the lead time for the airport with prevailing visibility greater than 1000m at 11:00 on 28th.

Published: May 2021

Abstract
Movable fluid parameter is an important index to evaluate the seepage characteristics of tight sandstone reservoir. Combined with high-pressure displacement and nuclear magnetic resonance movable fluid testing principle, the nuclear magnetic resonance movable fluid characteristics of six typical tight sandstone core samples of Xujiahe Formation in Central Sichuan Basin were studied. Based on mercury injection capillary pressure curve, the nuclear magnetic resonance T2 spectrum distribution was converted into pore throat According to the radius distribution, the minimum pore throat radius of the movable fluid and the contribution of different pore sizes to the movable fluid are determined. The research shows that the movable fluid saturation of the tight sandstone reservoir in the second member of Xujiahe Formation in Central Sichuan is closely related to the pressure difference, with good logarithmic correlation, and the main contribution to the movable fluid saturation is the reservoir space > 0.1 μm. 70% of the total movable fluid saturation is injected at a lower pressure (about 5MPa). In the later stage, high pressure injection can only enter the reservoir pore with small pore size, and the total amount is small and increases slowly. Therefore, the total contribution of high pressure drive to gas saturation in the later stage is small.

Published: May 2021

Abstract
With the continuous development of the Internet of Things (IoT), the application of blockchain technology to the Internet of Things has become a trend of the times. As we all know, the core of the blockchain lies in the consensus mechanism. In order to apply the blockchain to the Internet of Things, and for subsequent research needs, this research proposes a lightweight, high-throughput consensus mechanism system. Using scalable technology, any number of nodes and gateways can be set up. The experimental results show that the system throughput increases synchronously with the increase of the test load; in addition, when the test load is 800tps, the system throughput reaches the maximum value, which is close to 600tps. When the test load exceeds 800tps, the actual system throughput begins to drop, and about 90% of transactions have a delay time of 5000ms. This blockchain consensus system can be used for the simulation of lightweight IoT systems.
