SMART POSTPAID ELECTRICITY METER USING ARDUINO Revanda, Teuku Hilman; Ghofir, Abdul; Roestam, Rusdianto Manually dealing with electricity meters takes time because someone needs to access the postpaid electricity customer premises. Dealing with customers who fail to pay their electricity bills will be more complicated because specific action needs to be taken to cut off the power lines. A smart postpaid electricity meter is proposed in this research to overcome the above problems. This system is designed not only to record data of the amount of electricity usage but also to take action to cut off the electricity when the customer is in arrears. Arduino as a microcontroller is applied as the main control process. Internet of Things (IoT) technology is adopted to make the meter be controlled remotely through internet access. Required features and functionalities of the system are identified first before designing the system. Coding is written base on the design result. Unit test followed by integration test will be conducted to measure whether iteration steps are required or not. The test result shows that all proposed meter functions work well, so it can be said that the project works as expectations and the meter is ready to be used nationwide replacing the previous one.

THE ROLE OF PURCHASE INTENTION ON INTERNATIONAL FOOD BRANDS DURING COVID-19 PANDEMIC Liewin, Sant Louis; Genoveva Since the earlier of 2020, Indonesia has been fighting against Covid-19 and currently there have been more than four thousand people infected by Covid-19 per day. This raises fears of all sectors especially in business. All regulations and policies such as social distancing, health protocols, work from home, travel restrictions, and self-isolation at home have been implemented by the government. As a result, all workforce must be reduced in all economic sectors, which causes an increase in the number of unemployed. If schools and offices are closed, some of the populations are influenced to change their life into a healthy lifestyle in order to prevent any disease that will come to them. This case will impact to their trust towards the food-seller and they will decide whether they purchase or not. Hence, this research explains about the influence of the lifestyle towards purchase decision through customer trust as the mediating variable. The variables of this research such as the dimensions of lifestyle (activity, interest, and opinion) as independent variables, purchase decision as dependent variable,and customer trust as the mediating variable. This research is a quantitative research which using SmartPLS 3.0 (Partial Least Square Structural Equation Model). The online questionnaire spread to 171 respondents by snowball sampling. The result show that the positive influence of lifestyle (activity, interest, and opinion) on purchase decision. In additional, the lifestyle positive influence on purchase decision trough trust as the intervening variable.

THE CHANGE OF INDONESIANS LIFESTYLE TOWARDS FOOD PURCHASE DECISION DURING COVID-19 PANDEMIC Azmi, Amira Nurul; Genoveva The corona virus has attacked human life by taking away their freedom. Since the spread of the corona virus throughout the world at the end of 2019, every country has issued social distancing policies, including in Indonesia. The impact of this viral pandemic has damaged various existing businesses, including food franchises with international brands. The purpose of thisstudy isto analyze purchasing decisions at fast food franchises with international brands, assuming international brands already have cleanliness standards, high quality and a more comfortable environment (location), so that consumer confidence is more than other local brands. The trust factor is also used in this study as an intervening variable. This research is a quantitative study using an online questionnaire as a data collection tool. The valid questionnaires are filled in by 180 respondents. The sample used was non-purposived sampling with simple random sampling. Hypothesis testing uses the Structural Equation Model (SEM). The results showed that Food Safety, Food Quality and Environment had a significant effect on Purchasing Decisions during the COVID-19 pandemic. Meanwhile, Quality and Environment have a significant effect on trust, which is an intervening variable in this study. This study concludes that Food Safety, Food Quality, and Environment have a positive and significant effect on consumer confidence so that it affects purchasing decisions.

DEVELOPMENT AND VALIDATION OF THERMOCOUPLE FOR THERMODYNAMICS EXPERIMENT Anggraini, Lydia; Hernawan, Rendi Undergraduate students often struggle with Thermodynamics due to a lack of hands-on experience with the devices and sensors discussed in coursework. Traditional experimental setups—such as engine test benches and HVAC systems—are prohibitively expensive and maintenance-intensive, limiting student access and requiring large group work that can reduce individual engagement. To address this issue, we developed and implemented a costeffective thermocouple calibration apparatus for use in undergraduate Thermodynamics laboratories. The equipment utilizes affordable, readily available components, enabling the creation of multiple identical setups within a constrained budget. This allows students to work in smaller groups, increasing interaction and individual learning opportunities. The apparatus supports instruction in key Thermodynamics concepts, including temperature measurement, sensible and latent heat, and the Seebeck effect. Results from implementation show improved student comprehension and engagement. This approach offers a scalable, practical solution for enhancing Thermodynamics education, with potential applications across engineering curricula seeking to improve experiential learning within limited resources.
