Abstract

This study aims at examining the continued intention to use at electronics money consumer. Continued intention to use at electronics money consumer measured by security, trust, and customer satisfaction. This study obtained 162 respondents one of the largest citye in Indonesia, namely the greater city of Malang (including City of Malang, Malang Regency, and City of Batu). This study used SEM PLS and measured by SmartPLS 3.3.3. The result from this study are security and trust have a significant influence on the continued intention to use through consumer satisfaction as a mediation. The implication are the importance of increasing the sense of security, trust, and satisfaction of consumers so that they want to reuse electronic money; most consumers within the productive age who are very concerned about the security of electronic money and trusted electronic money institutions; most consumers are women; and it is also important to increase promotion, innovation, use of electronic money, to consumer loyalty of electronic money.

Abstract

Energy efficiency plays a crucial role in the initial design of chemical plants, as it directly influences operational costs and process sustainability. In sodium hydroxide plants, the substantial thermal energy demand, especially in heating and cooling units, necessitates effective energy optimization strategies. This study seeks to enhance energy efficiency in the preliminary design of a sodium hydroxide plant by incorporating heat exchangers (HE) through a Heat Exchanger Network (HEN) approach, utilizing the HINT application based on the Pinch Analysis method. Process stream data, including temperature, mass flow rate, and heat capacity flow rates of hot and cold streams, were analyzed to identify the pinch point, minimum heating and cooling utility requirements, and the optimal heat exchanger network configuration. The findings reveal that adding heat exchangers significantly boosts internal heat recovery and reduces the need for external utilities. Consequently, applying Pinch Analysis with the HINT application at the preliminary design stage of a sodium hydroxide plant effectively enhances energy efficiency, supporting a more economical and sustainable plant design.
