Handa Rivaldi Husal, Rosnani Ginting, Anizar Anizar — Mon, 29 Jan 2024 00:00:00 +0700

Value engineering is an organized, rigorous strategy that assesses the performance, noise, quality, safety, and compatibility of systems, outfits, installations, services, and inventories to deliver necessary functionalities at the lowest life cycle cost. Eliminating unnecessary expenses from design, testing, production, operations, procedures, accounting, conservation, and other areas is the best course of action. The purpose of the paper's initial investigation was to list the drawbacks of value engineering in product creation. These transgressions highlight the necessity for alternative methods when implementing value engineering techniques. To address critical inverse issues throughout the process, from the stage of product demand analysis to product design, product, and operation, value engineering is combined with various engineering methods. The results demonstrate that there are distinct paths in which the benefit of integration engineering using QFD or DFA may be used. Even so, this integration is providing a better option for the planning of products or services through a process that not only means providing a better value for client satisfaction but also lowers expenses, shortening development times, and reducing the need for rework conditions—all without compromising performance, reducing anxiety, or lowering the quality of the final product.

A Trust Model for Electrical Stove Technology Acceptance of Indonesian Stereotype

Mon, 29 Jan 2024 00:00:00 +0700

The surge in LPG consumption within Indonesian households, coupled with stagnant LPG production, has compelled the government to import 75% of LPG by 2022. Despite initial plans for a transition to electric stoves in 2023, the program was halted due to widespread public resistance to electric stove technology. The rejection was attributed, in part, to low trust in this emerging technology, emphasizing the pivotal role of trust in influencing technological acceptance. In response, this research endeavors to construct a robust and reliable model capturing trust in the acceptance of electric stove technology. Utilizing the PLS Structural Equation Model method for data analysis, the focus centers on two trust indicators: propensity trust and human-machine trust. In the quest for a valid model, the statistical modeling technique considers five initial hypotheses developed with 32 trust-related items. Upon analysis, one hypothesis is rejected, while four are accepted. Notably, the trust human-machine (THM) variable emerges as a significant influencer of trust for electric stove technology (TTK), substantiated by a path coefficient of 0.917 and p = <0.001. Thus, the resulting model takes on a reflective form, offering insights into the intricate dynamics of trust in the acceptance of electric stove technology.
