Abstract

This paper is under in-depth investigation due to suspicion of possible plagiarism on a high similarity index. This paper presents the computational of two-way fluid structure interaction technique by using Mesh based Parallel Code Coupling Interface for the visualization of wiresweep in the electronics packaging. Polymer rheology models with Castro-Macosko model have been used in the fluid flow model and Volume of Fluid technique was applied to melt front tracking of the fluid. The numerical analysis used User-Defined Function to allow curing kinetic model. Wiresweep profiles and pressure distribution within the mold are presented. The numerical results of melt front patterns and filled volume were compared with the previous experimental results and found in good agreement.

Abstract

The integrated circuit should be encapsulated for protection from their intended environment. This paper presents the flow visualization of the plastic ball grid array (PBGA) chip encapsulation process considering of the rheology effect. In the molding process, encapsulant flow behavior is modeled by Castro-Macosko viscosity model with considering curing effect and volume of fluid technique is applied for melt front tracking. The viscosity model is written into C language and compiled using User-Defined Functions into the FLUENT analysis. Three types of Epoxy Molding Compound namely case 1, 2, and 3 were utilized for the study of fluid flow inside the mold cavity. The melt front profiles and viscosity versus shear rate for all cases are analyzed and presented. The numerical results are compared with the previous experimental results and found in good conformity. In the present study, case 1 with greater viscosity shows the higher air trap and higher pressure distributions.

Abstract

The Unbalanced load with a significant difference in the electricity distribution system causes the emergence of a neutral current, causing losses due to the flow of neutral current to the ground, overheating in one phase, and resulting in a decrease in quality and damage to the distribution transformer if it lasts for an extended period of time.  The goal of this research is to design and build a monitoring prototype for measuring current, voltage, and percentage of unbalance on a distribution transformer prototype, with the goal of providing measurement data from the prototype via the internet. The Arduino Uno serves as a data processor from current and voltage sensors, and the ESP8266-01 serves as a wifi module, sending current measurement data for each phase, line to neutral voltage, and the percentage of load imbalance to the Thingspeak Web Server in the form of seven graphic displays that PC/ smartphone users can access online. The overall performance of this tool can work well by improving the measurement accuracy of the current sensor SCT 013-000 using a tuning approach, so that the resulting error meets the standard error of the measuring instrument.

Abstract

The COVID-19 pandemic has made indonesian people have to follow all health protocols made by the government, to overcome this virus requires movement of all sectors, including the research sector. The research sector is not only engaged in vaccines and drugs but also in efforts to reduce the spread of COVID 19 in Indonesia. This study aims to produce an RFID body temperature and attendance detection tool system using a web-based NodeMcu and produce a program that will send data to the web server. This tool is designed to be able to check body temperature and attendance more accurately and can be monitored directly by the user. The results of the study can directly detect body temperature using the MLX90614 body temperature sensor when someone approaches the sensor, the proxymity sensor will directly order the pump to remove the hand sanitizer liquid, and the RFID Reader detects the presence or attendance using the RFID Card. All data will appear on the LCD and enter the cloud server and will appear on the web page so that it can make it easier for users to carry out attendance activities in daily activities.

Abstract

Injection molding is one method that is widely used because of the lower cost required. The resulting plastic product is inseparable from the problem of product defects. This research uses quantitative methods and data collection or field on the subject of research, after that analyzing each parameter. The results of this study the occurrence of several defects in the product, namely short molding product defects have the most defects, namely 3, while over mold, sink mark and weldmark or flow product defects are 2 and the least is the hole product defect, namely 1. The setting at temperature determines the quality, especially in terms of appearance, at a temperature of 190 0C gives a much better product quality compared to temperatures of 180 and 200 0C. Analyze the optimal screw speed of 8 Rpm so that the resulting product can become a desired bottle product. Analysis of product defects that occur are Sink Mark, Weldmark or flow mark, Shrinkage and Over Mold which occurs at temperatures of 180 - 200 0C. The defects that most often arise because the mold has uneven lines so that defects occur in bottle products.

Abstract

At present, the need to use plastics and the advancement of manufacturing technology for the material itself drive people's demand for plastics, and the development of technology has further increased competition in all fields of industry. Therefore, the plastics industry needs to increase production in terms of quality and quantity. In this way, plastic can slowly replace iron and steel due to its good moldability and light weight. In this research, as a research method, we use quantitative methods by conducting surveys, data collection and field research related to the research theme. After the data is collected, the next step is the fabrication of the test equipment. From the mold fabrication results, the mold is in the shape of a 30 ml bottle with dimensions of 105 mm x 40 mm, inlet ø 6 mm, outlet 3 mm, and the mold is made of aluminum. This mold is called the 3 plate system and the mold consists of 3 main parts which are divided into 3 parts. Good and ideal molding results were obtained with HDPE (High Density Polyethylene) material with injection speed parameters of 8 rpm and temperature of 190°C.
