Abstract

Covid 19 has become a pandemic that has hit all over the world. Almost all sectors are affected by this pandemic, not only in the health sector. The economic and industrial sectors have also suffered severe impacts due to the coronavirus pandemic. This spreading virus does not support economic growth either nationally or globally. Finally, it has an impact on various industrial sectors in the country, from manufacturing to finance. The industry was one of the largest contributors to Indonesia's Gross Domestic Product (GDP) last year. The contribution given from this industry to the 2019 GDP was recorded at 19.62%. Due to this pandemic, according to the Central Statistics Agency (BPS), during February 2020, the importance of all categories of goods decreased compared to January 2020. This stunted industrial development was due to the government's appeal for social distancing; social distancing made it difficult for industry players to make transactions. Several obstacles require re-engineering of business processes in the industry. In general, the industry already has an Enterprise Resource Planning (ERP) system used in the related production process. However, ERP does not enter into the realm of buying and selling or the process of procuring goods with consumers. Therefore we need a Business Process Reengineering as an engineering process to integrate the ERP and the bidding system or quotation system. Using the moving average method as a forecasting method, we can get sustainable sales even during the Covid period, even seen an increase in transactions in the new period, along with the implementation of the quotation information system applied in the re-engineering business process.

Abstract

Abstract. Humans have limitations in processing and analyzing large amounts of data in a short time, including in terms of analyzing bankruptcy data. Bankruptcy data is one of the data that has complex information, so it requires technology that can assist in the process of analyzing and processing data more quickly and efficiently. Data science technology enables data processing and analysis on a large scale, using parallel processing techniques. Parallel processing can be implemented in machine learning models. Purpose: Using parallel processing techniques, data science technologies enable data processing and analysis at scale. Parallel processing can be implemented in machine learning models. Therefore, this study aims to implement a machine learning model using the Light Gradient Boosting Machine (LightGBM) classification algorithm which is optimized using Extreme Gradient Boosting (XGBoost) Feature Importance to increase the accuracy of bankruptcy prediction. Methods/Study design/approach: Bankruptcy prediction is carried out by applying LightGBM as a classification model and optimized using the XGBoost algorithm as a Feature Importance technique to improve model accuracy. the dataset used is the Taiwanese Bankruptcy dataset collected from the Taiwan Economic Journal for 1999 to 2009 and has 6,819 data. Taiwanese Bankruptcy is unbalanced data, so this study applies random oversampling. Result/Findings: The results obtained after going through the model testing process using the confusion matrix obtained an accuracy of the performance of LightGBM+XGBoost Feature Importance of 99.227%. Novelty/Originality/Value: So it can be concluded that the implementation of XGBoost Feature Importance can be used to improve LightGBM's performance in bankruptcy prediction.

Abstract

The sentiment is an assessment of attitudes towards certain events or things. Collecting opinion is known as a sentiment from existing data. This technique can also help analyze the opinions given by people in assessing certain objects. The best available source for gathering sentiment is the internet. In the era of the Covid-19 pandemic, many people access social media, especially Twitter to give their opinion on certain objects. Twitter is known as the social media that is accessed by users to post their opinions online. By using soft computing, especially fuzzy logic, it is possible to design, create and build bots that can analyze user opinions on Twitter. This model is used for data sentiment analysis on Twitter.

Abstract

The financial sector has been significantly impacted by informationtechnology, with digital banks emerging to provide services throughdigital platforms. SeaBank Indonesia, a digital bank, offers convenienceslike online account opening, free interbank transfers, and various digitalpayment options. However, some users have reported issues with theapplication, such as login problems and slow processing times.Additionally, some conventional customers remain hesitant to adoptdigital banking due to inexperience and security concerns. This studyaims to explore factors influencing users' adoption of SeaBank Indonesiaby applying the Technology Readiness and Acceptance Model (TRAM).Using a quantitative approach with purposive sampling, the researchcollected 421 valid responses from SeaBank Indonesia users throughonline questionnaires. Data analysis employed partial least squaresstructural equation modeling (PLS-SEM). The results accepted 8 out of12 hypotheses, revealing that intention to use is directly influenced byperceived usefulness, perceived ease of use, and perceived security.Perceived usefulness is directly affected by optimism, innovativeness,and perceived ease of use, while perceived ease of use is directlyinfluenced by optimism and innovativeness. These findings provideinsights into the factors driving digital banking adoption in Indonesia,highlighting the importance of user-friendly interfaces, perceivedsecurity, and technological readiness in shaping users' intentions to usedigital banking applications like SeaBank Indonesia.

Abstract

In the industrial world, distribution activities are one of the important things in the flow of a business process. The role of advances in information technology also has a considerable good impact on the process of exchanging information in business processes. The XYZ agency is responsible for organizing the distribution of plant seeds to all communities and farmer groups as an effort to improve the economy in the agro-industrial sector. However, there are obstacles in the distribution process activities carried out by the XYZ agency such as the lack of harmonization of information exchange with regional posts. This causes the distribution process to be hampered and also not even distributed. Therefore, it is necessary to describe the process flow using the Supply Chain Management (SCM) method to manage seeds distribution management appropriately. SCM elaborates each supply chain process in detail by categorizing each process with the attributes of plan, source, make, deliver, and return. In addition, performance measurement using the Supply Chain Operations Reference (SCOR) model is carried out to determine and provide recommendations for improvements needed for each related performance metric. There are 31 Key Performance Indicators (KPI) that are in accordance with the distribution process and validated in XYZ agency. The result of performance measurement based on the Key Performance Indicator reached 83.12, which indicated the performance monitoring of the actual seeds distribution process by XYZ agency at the Good level.

Abstract

One of the efforts in handling educational challenges in the era of technological development is the development of the Thesis Information System for Dissertation Thesis (SITEDI). SITEDI is an information system that facilitates the thesis administration process starting from the presentation of the subject matter to the final exam managed by Universitas Negeri Semarang (UNNES). Therefore, it is necessary to measure the quality of SITEDI performance based on user satisfaction to facilitate the evaluation process of SITEDI as a quality student service in the future. The research method used in this study is a combination of WebQual 4.0 and End-User Computing Satisfaction (EUCS). The variables used include usability quality, information quality, service interaction quality, format, and timeliness. The sample used was 135 respondents with purposive sampling technique. The results of the analysis that have been carried out conclude that simultaneously the variables of usability quality, information quality, service interaction quality, format, and timeliness have an influence on user satisfaction by 62.5%. WebQual 4.0 variables, namely service interaction quality, information quality, and usability quality sequentially have a significant influence on user satisfaction with an effect size of 0.092, 0.069, and 0.028. Meanwhile, the EUCS variables, namely format and timeliness, do not have a significant influence on user satisfaction.
