Abstract

In Indonesia, there are several forms of exports, one of which is oil and gas exports. The Double Exponential Smoothing method is a forecasting method that can be used to forecast oil and gas export data. This method uses two smoothing parameters, namely the average smoothing parameter alpha (α), the trend smoothing parameter beta (β). In this study, the population used is data on oil and gas exports in Indonesia. And the sample used is Indonesia's oil and gas export data from January 2020 to October 2021, we get 22 data sourced from the Central Statistics Agency (BPS). The Double Exponential Smoothing method is used because the data to be processed has a trend, both an up and a down trend and gas exports in Indonesia have an up and down pattern. The Double Exponential Smoothing method can also predict the prediction of oil and gas exports in Indonesia in the next months, November 2021 to February 2022. To process the data, the researcher used the Holt Double Exponential Smoothing method .

Abstract

Indomaret and Alfamart are minimarket businesses that are currently experiencing significant growth, especially in the city of Salatiga. Each company strives to achieve maximum profit, and thus, it is essential to determine the most optimal competitive strategy to attract customers. This research was conducted using a questionnaire to understand what influences consumers in choosing a minimarket for shopping, providing valuable insights for determining minimarket strategies. Game Theory is employed to represent the respondents. The results of the study indicate that Alfamart will employ a location-based strategy in their stores, while Indomaret will utilize discount and promotion strategies for their easily accessible minimarkets.

Abstract

The rapid advancement of information technology has significantly impacted various sectors, including public service. The Indonesian government's M-Paspor application, designed to streamline the passport application process, has faced several user experience challenges, such as complicated registration processes, inaccurate location selection, and difficulty in finding queue schedules. This study aims to analyze and redesign the M-Paspor application using the Design Thinking method, a user-centered approach involving empathy, problem definition, ideation, prototyping, and testing stages. Through a thorough literature review and usability analysis, we identified key issues affecting the application's performance based on four usability indicators: learnability, efficiency, errors, and satisfaction. The redesigned interface, developed using the Design Thinking framework, addresses these issues by improving clarity, navigation, and overall user experience. Our findings indicate that the redesigned M-Paspor application significantly enhances user satisfaction and efficiency, ultimately supporting the government's vision of effective and efficient e-governance. This study not only provides practical solutions for improving the M-Paspor application but also offers insights into the application of Design Thinking in public service technology design.
