In selling packaged rice products, Perum BULOG needs to implement the right marketing strategy in order to increase the buying interest of prospective consumers. This study aims to analyze factors that affect brand equity and purchasing decisions of packaged rice products. The research design uses a descriptive approach through surveys by disseminating questionnaires online. The research was conducted in September-October 2020 on 270 rice consumers in DKI Jakarta and Bodetabek who were selected using nonprobability sampling method through convenience sampling technique. The variables studied in this study were product, price, place, promotion, brand equity, and purchasing decisions. Data analysis method using SEM analysis with Lisrel 8.80 software. The results showed that product, price, place, and promotion had a significant positive influence on brand equity and purchasing decisions. The variables that most influence purchasing decisions are product, place, and brand equity. Based on the results of the study, it can be concluded that product, place, and brand equity are factors that should be a top priority for manufacturers to make improvements and development. In addition, rice products sold using brands and packaging are more attractive to consumers than rice products sold without brands and packaging. In this regard, in addition to the marketing mix strategy, manufacturers must implement brand and packaging strategies well to improve consumer purchasing decisions on their rice products.

The aerodynamic aspect is one of the most important things in the automotive sector which is used to find information on the performance of an aerofoil model design. The performance of an aerofoil through streamflow associated with fuel consumption which means the higher the air speed, the greater the resistance received, so that the fuel consumption will be greater. At this case, fuel consumption can be reduced by creating an aerofoil model design that maintain great aerodynamic to minimize drag forces. The affects of streamflow around the vehicle are discussed in this papper. This research simulated 3D electric vehicle Tobacco Style M-164 in steady condition with various velocities, i.e. 50 km/h, 60 km/h, 70 km/h, and 80 km/h. This simulation use the Tethahedron mesh model and run in SST k-omega turbulence model. The affects can be observed with the quantitative and qualitative data. The quantitative data used as measurable data were Maximum Fluid Pressure, Drag Force, and Coefficient of Drag (CD). The quantitative data is shown to provide a better visual explanation of the streamflow affects. The qualitative data shown in this paper are velocity contours, vectors, and pathlines. The value of the maximum fluid pressure and drag force is directly proportional to the increase in velocity stream. The coefficient of drag decreased as the free stream increased with a percentage decrease of 2.48%. The average value of the coefficient of drag (CD) from this research was 0.318.
