作者： F Bari J A Repadi F A Ismail riani A Hakam Doctoral Program Dept. Of Civil Eng Faculty Of Engineering Andalas University Indonesia. Lecturer Dept. Of Civil Eng Faculty Of Engineering Andalas University Indonesia.

Many failure cases of retaining walls caused by some factors, which are soil condition, planning design that did not meet the safety requirements, and the lack of knowledge or indecisiveness towards the selection of the retaining walls type for a specified height. In this research, the optimum height of a retaining wall of gravity wall type for sandy soil was planned. The research methodology was done by calculating external and internal stability from a stone gravity retaining wall. From the external stability analysis of 4 - 14 meters heights, it is known that the retaining wall still safe. The internal stability analysis obtained from 8 meters heights did not meet the safety requirements. Therefore, it is recommended from the research to use the height of 7 meters for the stone gravity retaining wall. The optimum height of retaining wall is planned in this research as the guidelines for engineers in planning the right retaining wall for the height as planned.

This paper examines the thermal condition aspects of traditional Acehnese houses (Rumoh Aceh) in Indonesia. This study highlights the importance of considering traditional architecture in achieving comfortable living conditions. Through the integration of cultural values, architectural design, and environmental factors, this research evaluates the prediction of thermal conditions within Rumoh Aceh based on building orientation and location, serving as guidelines for architects in designing buildings in the Aceh region. The study employs an ANN (Artificial Neural Network) algorithm to predict thermal condition parameters including indoor: temperature, humidity, and wind speed. The sample data used to train the ANN model consists of thermal data from five different rooms and meteorological data. The ANN model is employed to predict the thermal conditions in the Rumoh Aceh building based on its orientation and location. In this study, two models were developed, namely MODEL_01, for predicting indoor temperature and humidity, and MODEL_02, for predicting indoor wind speed. In MODEL_01, the error tolerance level obtained is ±1.05, and in MODEL_02, it is ±0.03. The prediction results based on the building orientation show the lowest average indoor temperature value of 29.19 °C, occurring at an angle of 292.19°. Furthermore, the lowest average indoor humidity value is 74.57 %, which also occurs at an angle of 292.19°. However, for indoor wind speed, the angle of 260° records the lowest average value of 0.125 m/s, while the highest average value is observed at 292.19°, at 0.132 m/s. The prediction results based on the building's location show the lowest average temperature value, which is 29.44 °C in the Aceh Besar region. Furthermore, the lowest average humidity value is 75.11 % in the North Aceh region. Meanwhile, the highest average wind speed value is 0.174 m/s in the Sabang region. This study reveals that at the orientation angle of 292.19° (the qibla direction), it pr

引用

IOP Conference Series: Materials Science and engineering 2018年第1期434卷

作者： N Fadhly R Matondang Department of Civil Engineering Engineering Faculty of Syiah Kuala University Darussalam Banda Aceh Indonesia Doctoral Program in Regional Planning University of North Sumatra Indonesia

The occurrence of spatial and road network changes, increased traffic volume approaching road capacity, causing congestion due to urban sprawl phenomena as well as lack of public facilities and social facilities. From this background problem considered to be solved by a concept that is Transit Oriented Development (TOD), concept of transportation development in co-operation with spatial. The TOD concept can eliminate urban sprawl, which transforms urban sprawl into a compact city area. Pull model are obtained from the results of the analysis is, Oi = -37,126 + 58,723 X9 + 17,968X2, where road performance, land use, the coefficient indicates the number of additional trip generation. Trips pull obtained by model Dd = -20,351 + 30,903X2 where only one significant variable causing attraction of land use that is dominant. With concept of TOD, the model obtained is Oi = 32.180 + 0.002X7-7.017X3 where travel and distance travel costs indicate the number of additional trips generation, the generation will decrease over the base year. Objects obtained with the model Dd = 48.474-0.671X11 + 0, 003X7-9,299X3, meaning travel attraction in the absence of population density, travel expenses, and travel distance, then travel appeal that occurs on 48 journeys influenced by variable population density and distance travel will decrease, it can be interpreted this independent variables can influence the drag on the concept of Banda Aceh City and TOD can be applied in the city of Banda Aceh.
