The investigation demonstrates that spin splitting is found when a favoured orientation of organic cation align along the [111], the [101] and the [011] directions. We show that Rashba splitting is induced with the anisotropical character of spin polarization in [111] directions, whereas the unidirectional out-of-plane of spin polarizations are achieved in [011] and [101] directions. By employing   perturbation theory based on symmetry consideration, we find a large spin-orbit strength from these splitting. These findings show that the bulk HOIP CH3NH3PbX3 is a promising material for the development of perovskite-based spintronic devices.","PeriodicalId":229685,"journal":{"name":"Jurnal Teknik Transportasi","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124202958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Argo Parahyangan train and freight train are passing through this track. Therefore, it is crucial to build double track lane. However, it is difficult to execute due to a wide and deep river which requires a new bridge with a complex high cost construction. That is the reason why, an in-depth evaluation of the bridge design is needed. In selecting the bridge design, the Analytical Hierarchy Process  was used as the selection method. The method would applied a four-level developed structure: the first level was the goal of choosing the Optimum Bridge Design, the second level was the people involved, the third level was the evaluation criteria, the last level was the alternative bridge to be built. The data was taken from the questionnaires filled by six respondents of the railway bridge's construction experts. The results show that the order of the bridge's design selection is as follows: 0.395 for concrete bridges; 0.213 for steel arch bridges; 0.199 for steel frame bridges; and 0.194 for cable bridges.","PeriodicalId":229685,"journal":{"name":"Jurnal Teknik Transportasi","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116044302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Camplong Beach has a coastline that is very close to the highway. The existing beach protector is less able to resist erosion so that in some locations the Camplong Highway is damaged due to coastal erosion. Coastal protective structures needed are revetments and groins to resist erosion and poorly distributed distribution of sediment transport. The calculation starts with collecting wind data, tidal data, and bathymetric maps. Then the location survey, fetch calculation, repeat period analysis, refraction analysis, break wave calculation, shoreline change, layout planning, and detailed structural design.

The percentage of downtime when the design is calculated to be distributed in a period of time can last for several weeks and cause a break in the supply of coal to the power plant in a long period of time. Regarding this condition, it is necessary to use bigger ship capacity. The size of ships served in some PLTU must be evaluated. This article discusses a case of port capacity evaluation in one of PLTU in Southern Coast of Java if it was able to serve a ship with bigger size. An evaluation to the capacity of pier pole structure was done by using SAP2000 software and the evaluation of pier dimension, fender and bollard capacity, as well as the depth and the area of existing turning basin that have been done by using port design standards. The result of the evaluation is an early indication for the size of ships which still can be served by the existing port PLTU.      ","PeriodicalId":229685,"journal":{"name":"Jurnal Teknik Transportasi","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117184421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
