In planning residential development, this should not be underestimated, because apartment construction involves the safety of its residents. To build a house in a residential area, it must also meet government regulatory standards. The Subsidized Housing Project in Taktakan District, Serang City, was built on an area of ±103.870 m 2 , consisting of 913 units of type 27. To assess the investment costs and benefits to be obtained by the developer, a feasibility study is necessary. The housing feasibility study was analyzed from various aspects including technical aspects, government policies and financial aspects. Analysis of the financial aspects of this study using Net Present Value (NPV), Cash Benefit Ratio (BCR), Profitability Index (PI) and Internal Rate of Return (IRR) referring to the Serang City Spatial Plan (RTRWK Guidelines) 2010-2030.

Penurunan jumlah kendaraan berpengaruh pada kinerja simpang Pertigaan Pendem. Metode yang digunakan untuk mengetahui kinerja simpang yaitu berdasarkan manual kapasitas jalan Indonesia tahun 1997. Parameter kinerja simpang adalah derajat kejenuhan, tundaan, probabilitas antrian. Dari perhitungan didapatkan nilai DS adalah 0,31 dengan nilai tundaan berkisar antara 2,39 sampai 7,06. Sehingga kinerja simpang berada pada level B yaitu Baik. Selama masa pandemic Covid 19, terutama pada saat diberlakukannya PPKM level 1-4, dan pada saat survei dilaksanakan, Malang Raya sedang berada pada PPKM Level 3.

The analysis of the deflection that occurs due to the load needs to be carried out so that it does not exceed the permit deflection requirements because the deflection can affect the stability of the structure, the performance of rigid pavement, and the design life of the road. The purpose of this study was to determine the deflection of rigid pavement with variations in plate thickness and variations in loading positions. This research method uses the finite element method. The variation of plate thickness used is 150 mm; 200 mm; 250 mm; 300 mm; and 350 mm with center, end, and edge loading positions. Pavement deflection for center loading and edge loading meets the permit deflection requirements, while for end loading, only 150 mm thick slabs meet the permit deflection requirements. That can be caused by the low bearing capacity of the soil. Plate thickness is influential on the deflection; the thicker the plate, the higher the stiffness of the plate, the smaller the deflection will be.","PeriodicalId":52898,"journal":{"name":"Teras Jurnal Jurnal Teknik Sipil","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47246148","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}
