Gedung Kuliah Bersama is located at the UPN “Veteran” East Java in the city of Surabaya. Geologically and tectonically, Surabaya City is in an active fault zone, so that the tectonic activity that occurs can cause damage to building structures and construction materials. Pushover analysis is an analysis that can be used to determine the pattern of structural collapse when an earthquake occurs. Based on the results of the analysis, precast pretension slabs (hollow core slabs) with segments of 1500 mm × 7000 mm × 150 mm with PC Wire reinforcement ϕ7-121 mm and cast in situ (steel deck) slabs with a thickness of 120 mm with wiremesh reinforcement M8-150 mm. The difference in the bending strength of the two types of slabs is 38.73%. The results of the pushover analysis show that the structural performance at the Damage Control (DO) level shows that the building is able to withstand the earthquake that occurs and the risk of casualties is very small. \u0000 \u0000 \u0000 \u0000","PeriodicalId":265863,"journal":{"name":"CI-TECH","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126014405","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}

As technology develops, people's desire for good telecommunications technology is enhancement. The writer analyzes the tower with type v bracing and type x bracing using the SAP 2000 application. BTS towers are used with a height of 25 meters, width of 6 meters, length of 6 meters, height of each segment of 2.5 meters. Then analyze the strengths using the SAP 2000 application based on the TIA / EIA 1991 standard with displacement not exceeding H/200. After the SAP 2000 application is finished running, the results of the building's own weight output are used for economic comparisons. The results of type v bracing analysis obtained a displacement of 0.4 millimeters with a building own weight of 123.668 KN. The result of type x bracing analysis obtained a displacement of 0.6 millimeters with a building weight of 143,440 KN. The results of this analysis recommend the BTS tower to use type v bracing instead of using type x bracing. \u0000 \u0000 \u0000 \u0000","PeriodicalId":265863,"journal":{"name":"CI-TECH","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132428557","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}

Payments method by using this plastic waste of drinking bottle in order to complying the objectives of Surabaya Municipality is reducing plastic wastes also citizens shouldn’t make a littering anywhere. This research is conducted to calculate how much Suroboyo Bus fares that sufficient with existing payments method due to Suroboyo Bus operations needs with using Willingness To Pay (WTP) analysis and Vehicle Operations Cost regulations.As the research results value of Willingness To Pay on weekday is IDR 4.784,12 and then on weekend is IDR 4.602,50.
