Abstract

Innovation and technological progress have significantly impacted various sectors, notably Indonesia's financial and banking industry. This sector has seen remarkable growth, particularly with the rise of digitalization. A prominent development in this context is financial technology, or fintech, which has emerged to address needs and issues not sufficiently met by traditional banking services in Indonesia. Among fintech innovations, Transfer and Payment technologies have become increasingly popular. Despite these technologies' benefits, they are frequently criticized for various usage-related issues. This study uses the Modified E-Servqual and Importance Performance Analysis (IPA) methods to evaluate the service quality of Transfer and Payment applications in Indonesia. It aims to assess user perceptions and expectations, identify areas for improvement, and determine which service dimensions require enhancement. The research involved 400 respondents who used Transfer and Payment applications. To ensure reliability, the Kuder-Richardson (KR-21) formula is applied to the measurement tool, while descriptive analysis and IPA are utilized to evaluate and map service quality. Findings reveal that user perceptions of the Transfer and Payment applications are rated as ‘good,’ with an average score of 4.01 out of 5.00 (80%). User expectations are slightly lower, at 3.93 out of 5.00 (79%), but still categorized as ‘good.’ However, several attributes fall short of user expectations, particularly in Reliability, Personal Needs, User Friendliness, and Responsiveness.

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.
