Abstract

Land subsidence in the areas of Pademangan, Ancol, Penjaringan, Cengkareng, Tanjung Priok, Cilincing, and Pulogadung is still ongoing. The land subsidence is influenced by the condition of the groundwater table and the effect of consolidation. The purpose of this research is to know the result of soil subsidence/ consolidation using conventional calculation methods and geodetic GPS observations on R.E. Martadinata Street on Bore Hole 3 with Point BM.CP.1 and Bore Hole 6 with Point BM.DKI.11 and to find out the results of the comparison of subsidence/ consolidation analysis methods between conventional calculations and geodetic GPS observations. The amount of soil subsidence/ consolidation with conventional calculation methods at Bore Hole 3 with Point BM CP.1 obtained 8.5 cm with a period of 2.3 years and at Bore Hole 6 with Point BM DKI.11 obtained 5.6 cm with a period of 0.4 years. The amount of soil subsidence/ consolidation with GPS Geodetic observations BM CP.1 point was obtained at 16.8 cm with a period of 3 years and at the DKI.11 BM Point obtained 17.5 cm with a period of 3 years. The results of soil subsidence/consolidation calculations using conventional calculation methods and GPS Geodetic observations there was a difference or deviation in Bore Hole 3 with Point BM CP.1 obtained 8.3 cm with a period of 0.68 years and in Bore Hole 6 with Point BM DKI.11 obtained 11.9 cm with a period of 2.64 years.

Abstract

Many things influence consumer purchasing decisions, both internal and external factors, especially with the shift in several purchasing methods in the digitalization era. Theory of planned behavior analyzing important components that have a direct impact on consumer decisions, namely attitude, subjective norms, and perceived behavioral control. Through this literature, usage will be explained theory of planned behavior on purchase offline and online, as well as its development through analysis of several academic journals. Use Systematic Literature Review (SLR) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), this research synthesizes scientific evidence and answers the objectives of the research. The time period chosen for this international standard journal is 2019-2022. Found 47 eligible journals according to the selected keywords. Next, process screening with theories and concepts carried out, so that the detailed analysis reviewed focuses on the 30 selected academic journals. The research results stated that the components Perceived Behavior Control on Theory of Planned Behavior, has the most influence on purchasing decisions. Apart from that, socio-demographic characteristics can also be added as supporting variables that can influence consumer purchasing behavior.
