User Interface Design With User Centered Design (UCD) Method on Bread Sales Mobile Application PT.Nippon Indosari Corpindo, Tbk

PT. Nippon Indosari Corpindo,Tbk. is one of the companies engaged in the food industry with its flagship product, namely bread with the brand "SARI ROTI". PT Nippon Indosari Corpindo,Tbk has been established since 1995. At PT Nippon Indosari Corpindo,Tbk, according to the author, the online buying and selling system used is not yet effective and efficient, because customers have to click the link to whatsapp to order, if the order has been entered then from the agent The center provides information to the nearest agent according to the location of the order ordered by the customer, and afterthat the nearest agent canonly send the order. Therefore, there is a lack of efficiency in the purchasing system. The problem isthat it does not yet have a prototype user interface for the Sari Roti mobile application. Based on these problems, user interface design was carried out and produced a prototype of the Sari Roti mobile application using a user centered design (UCD) model and for evaluation of the initial design using a usability scale (SUS) system to 11 respondents. This research is successful in designing a user interface that can view product lists, product details, make transactions, and order status. The initial design evaluation uses a usability scale system with initial calculations showing an average valueof 82,withGrade B

Static strength prediction of adhesive joints: A review

The use of adhesive joints has gathered increasing interest in recent years due to their advantages over conventional bonding techniques, namely lighter structures and decreased stress concentrations. Consequentially, the strength prediction of adhesive joints has been studied extensively. This review aims to describe and compare the most relevant methods for the strength prediction of adhesive joints. These methods can be divided into analytical and numerical methods. Analytical methods are generally limited to initial design evaluations or to simple joints. Numerical methods are more commonly used, especially when joint design is complex. Between the different numerical methods, Cohesive Zone Models (CZM) are the most popular method to predict the strength of adhesive joints. This approach is able to predict the strength of a wide range of joint designs with minimal errors. However, it requires the determination of cohesive laws that generally change depending on different geometrical parameters of the joints. Advanced numerical techniques, such as the eXtended Finite Element Method (XFEM) or Meshless Methods have been used to study adhesive joints, but their application needs improvements before they can be more extensively used.

CFD Study of Tidal Current Turbine Shroud for Initial Design Evaluation

CFD simulation of a tidal current turbine shroud was performed using Ansys FLUENT commercial code and comparison was made with experimental data. The simulation result obtained was in good agreement with the experimental data. The coefficient of velocity, Cv was in the range of approximately 1.2 to 1.4 for both simulation and experiment. The present study gave useful information on the viability of CFD simulation for the initial evaluation of shroud design performance.
