Abstract

This study aims to develop effective policies and strategies to promote the adoption of IoT technologies, particularly smart home usage in Indonesia, in light of the rapid increase in internet usage and to address the digital divide due to varying education and income levels. Utilizing the Technology Acceptance Model (TAM) and a quantitative methodology, the survey was conducted with 427 smart home users via a digital form distributed on social media. Data was analyzed using TAM variables and additional variables like privacy, compatibility, perceived ease of use, perceived usefulness, attitude towards using, behavioral intention to use, and actual system use, with demographics (income and education) as moderating variables. The results show that privacy, perceived ease of use, and perceived usefulness significantly influence attitudes towards using smart homes, which in turn positively affects users' intention to use them, while compatibility does not. Education and income levels weaken the relationship between external factors and intention to use smart homes. This research highlights the impact of demographic factors on IoT adoption and provides insights for technology providers and policymakers to enhance smart home device adoption in Indonesia.

Abstract

Traveling salesman problem (TSP) is the problem of a salesman to visit the city of each city connected to each other and there is the weight of travel between the cities so as to form a complete weighted graph. Departing from a certain initial city, a salesman had to visit (n-1) another city exactly once and return on the initial city of departure. The purpose of TSP is to find the route of all cities with minimum total weight.Many algorithms have been found to solve the TSP, one of which is the Cheapest Insertion Heuristic (CIH) algorithm in the process of inserting weighted steps obtained from the equation c (i, k, j) = d (i, k) + d (k, j) - d (i, j). This algorithm provides different travel routes depending on the order of insertion of cities on the subtour in question.In this final project, the writer took the problem of distribution route of mineral water of al-ma'some 240 ml cup type, with vehicle capacity to meet 1200 carton and have different customer / agent demand that is the distance of depot and agent far from each other, distribution costs.

Abstract

Most developers still use the monolithic architecture, where all components of an application are combined into one integrated system, so each part depends on other components. The monolithic architecture has weaknesses, such as when a failure occurs in one component, all parts cannot be executed because each component relies on one other component. Microservices can be a solution to this, considering that in the microservices architecture, each element or service is created and put separately, so when a failure occurs in one component, other components will not be affected and can still run normally. This research aims to determine the implementation and performance comparison between monolithic architecture and microservices Architecture in the Agreeculture Market web app. Agreeculture Market is a web application that aims to facilitate the transaction process of agricultural commodities and make it easier for agricultural commodity producers to market their products. The measurement method used to measure the performance of both architectures is load testing using JMeter and performance tools from task manager and comparing the response time, throughput, disk usage, CPU usage, and memory usage of both used architectures. With two measurement schemes with Docker and without Docker, the result of this research is a performance comparison between the two architectures, where the backend application Agreeculture Market, which uses microservices architecture with Docker and API gateway, performs better than the monolithic architecture version. Conversely, the monolithic architecture performs better than the microservices architecture in the scheme without Docker and API gateway.

Abstract

User privacy and security concerns hinder the adoption of biometric authentication technology in Indonesia, especially when consumers are still determining how their biometric data will be stored, accessed and used. This research aims to investigate the variables that influence the adoption of biometric authentication technology in Indonesian society. The Technology Adoption Model is used in this research to estimate the impact of different parameters and investigate the importance of novel elements in adopting biometric authentication. Several factors are examined to see how they affect Actual System Use (ASU), including Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Trust & Security (TS), Perceived Privacy (PP), Attitude towards Using Technology (ATU), and Behavioral Intention to Use (BIU). New theories are presented in this study, focusing on the relationship between PP and BIU, which is supported by respondent data. The results show the rejection of two hypotheses: first, the effect of PU on BIU may not be strong enough to influence user intention, and other variables may be at play; second, the effect of PEOU on BIU implies that perceived ease of use alone may not be sufficient to influence user intention. BIU has a major impact on the adoption of biometric authentication technologies. Furthermore, this research found that compared to PU and PEOU, the original components of TAM BIU are more influenced by variables such as ATU, PP and TS. These results suggest that new considerations such as privacy, trust, and security are more influential in shaping usage intention in biometric authentication.

Abstract

Purpose: The study investigates the fast-evolving fintech landscape, specifically the impact of digital wallets on the financial industry. It focuses on the competitive digital wallet market in Indonesia, examining how service quality influences user satisfaction and loyalty in a saturated market. By integrating a Security variable into the E-Servqual method, this research aims to offer a new perspective on assessing the effects of digital wallet services on user satisfaction and loyalty. Methods: This study employs the Modified E-Servqual model with an added Security variable to explore how service quality variables like Site Organization, Efficiency, Personal Needs, Privacy, Reliability, Responsiveness, Security, and User’s Friendliness impact customer satisfaction and loyalty in digital transactions. Surveying 287 digital wallet users, mostly GoPay, OVO, ShopeePay and DANA, the research provides a detailed analysis of these variables' effects on E-Customer Satisfaction and E-Customer Loyalty. Result: The findings show that digital wallet users value certain service quality aspects differently in terms of their impact on satisfaction and loyalty. While variables like Reliability, User’s Friendliness, Personal Needs, Privacy, Security, and Efficiency significantly influence user satisfaction, Site Organization and Responsiveness do not. This highlights the importance of security and efficiency in enhancing user satisfaction and loyalty in digital wallets. Novelty: The study's novel contribution is integrating a Security variable into the E-Servqual method, enhancing the assessment of digital wallets' inherent security risks. This integration provides a detailed analysis of how security impacts user satisfaction and loyalty, alongside other service quality factors. This systematic evaluation offers new insights for improving service quality, benefiting companies in the competitive digital wallet market, and informing future research on customer loyalty and provider success.
