Abstract

The current industrial implementation process is required to be carried out efficiently and environmentally friendly, this can be done with the presence of a heat exchanger. However, heat exchangers in the production of aluminum nitride nanoparticles are still rare. The purpose of this research is to analyze and improve the heat exchanger design in the production process of aluminum nitride nanoparticles at low cost. The heat exchanger can be designed based on several parameters of the TEMA standard by dimensional specification and specifications of hot and cold fluids. The method is calculated using a Microsoft excel application to evaluate the heat exchanger design according to the TEMA standard. The results showed that the shell and tube heat exchanger was designed with 39 tubes and an effective value of 85.72%. These results have met the TEMA standard and it is hoped that the design and evaluation of this heat exchanger can be used as a reference in the aluminum nitride nanoparticle production industry.

Abstract

Curriculum changes become the realization of ideas and the design of a learning process that emphasizes aspects of knowledge, skills and attitudes. SMAN 1 Mertoyudan implements several curricula in processing its grades which have been adjusted to Kemendikbud decisions. Currently, the scoring system is still done manually and processed by the homeroom teacher so that student guardians have difficulty monitoring children's grades during the teaching and learning process. Therefore, it is necessary to have a value monitoring system that can be accessed by student guardians online so that student guardians can find out from an early age student learning achievements. The monitoring system also provides easy access for subject teachers and homeroom teachers to manage grades, find out student learning achievements and provide assistance to students through student guardians. The system is designed to have a responsive display so that it is easily accessible from smartphones and laptops according to the web view on devices used by student guardians. This research builds a school academic monitoring system using a web-based dashboard. The results of the tests that have been carried out show that the user satisfaction level is 87.5% which can be concluded that users feel that the system created is easy to understand and understand.

Abstract

Social media as a means of communication can also be a place for branding, entrepreneurship and marketing. Various apps are very easy to access including online dating apps. The Tinder app is an online dating platform that came into existence in 2012 and has the highest percentage in 2022 compared to other online dating apps. Communication plays an important role in the message exchange that occurs in the Tinder app. The established communication patterns will affect the first impression when meeting in the media. Every human being has expectations of non-verbal messages or behaviors from others. This study aims to analyze the theory of violation of expectations of tinder app users as a communication intermediary to establish relationships. This study used a qualitative descriptive method by conducting structured interviews with active users of the Tinder application. Interviews were conducted to find out the informant’s perspective when using the application. Assumptions arising from the violation of expectations result in the non-occurrence of the same expectations. Based on the results of research, the tinder application is not only to find a partner but also can add relationships both in the world of lectures and in the world of work. Then, two out of three tinder app respondents managed to achieve expectations in using the tinder app.

Abstract

Education is very important along with the advancements in technology that required people to have in-depth and quality knowledge. A person who can get a job usually has a good educational background. How long it takes a person to get a job is affected by many factors. In statistical sciences, factors affecting how long a person gets a job after graduating from college can be studied using survival analysis. Survival analysis is a regression method used to examine the factors that influence the occurrence of one or more events. Several survival models can be used to estimate the impact of survival factors on how long a person gets a job, including the cox proportional hazard model and the accelerated failure time model. The cox proportional hazard model belongs to the semi-parametric approach where the hazard function essentially follows the non-parametric model while the independent variables follow the parametric model. The accelerated failure time model is a parametric model based on data distribution that can predict the time of the event in observed data. This study was conducted by comparing the cox proportional hazard model and the accelerated failure time model with the logistics distribution to determine if the conditions or data types are better identified with the cox proportional hazard model or the failure time model. time. The results obtained by considering the minimum AIC value, the accelerated failure time model has a better logistics distribution than the cox proportional hazard model.
