Abstract

Arkem Coffee Cirebon is an MSME coffee shop located on Jalan Arya Kemuning, Kesambi District, Cirebon City. The sales process for Arkem Coffee Cirebon is carried out conventionally/offline. The problem of the unavailability of the online sales process requires an information system to overcome this problem, namely by using ERP implementation through social commerce. The ERP implementation method uses a social commerce approach, which is a system created using data and procedures to provide products and services through social media applications. This method was chosen because the owner experienced obstacles in developing products and services. This method was deemed able to overcome these obstacles because he saw that the development of sales through online media was accelerating rapidly and could be easily operated by the coffee shop. This research method uses descriptive research methods, interviews and observations. Designing an overview of online business processes is carried out using the business process re-engineering method. Through the implementation of this information system and design, Arkem Coffee Cirebon can implement online business processes in its business.

Abstract

Rice is a type of plant that is very essential for humans. Rice is used as a staple food by a large portion of people, especially in Asia. Therefore, proper care and management of rice plants are crucial to maximize crop yields and meet the food needs in Indonesia, particularly for the staple diet. One of the common factors that hinder rice production is diseases that affect rice plants. If left untreated, it can have a detrimental impact on the much-needed rice production in Indonesia. Some common rice diseases include Bacterial Leaf Blight, Brown Spot, and Leaf Smut. Hence, early detection is required as a preventive measure against these diseases. One way to address this issue is by applying artificial intelligence, where AI can play a significant role in disease identification in rice plants. This allows farmers to take clear actions in disease management. Identification is performed using leaf images and an Artificial Neural Network (ANN) algorithm with an accuracy of 83%.

Abstract

This study undertakes a comparative analysis of machine learning and deep learning models for forecasting the impacts of climate change, utilizing Cross-Validation Root Mean Squared Error (CV RMSE) to gauge performance. Analyzed models include Long Short-Term Memory (LSTM) networks (CV RMSE: 0.155), Linear Regression (CV RMSE: 5647815244.91), Random Forest (CV RMSE: 0.159), Gradient Boosting Machine (GBM) (CV RMSE: 0.164), Support Vector Regressor (SVR) (CV RMSE: 0.159), Decision Tree Regressor (CV RMSE: 0.199), and K-Nearest Neighbors (KNN) Regressor (CV RMSE: 0.166). The study rigorously processes climate change time series data to ensure accurate, generalizable results. LSTM networks demonstrated exceptional performance, indicating their strong capacity for modeling complex temporal sequences inherent in climate data, while Linear Regression lagged significantly behind, revealing limitations in addressing non-linear patterns of climate change. The promising results of Random Forest and SVR models suggest their applicability in environmental science forecasting tasks. Our findings offer valuable insights into the efficacy of various predictive models, aiding researchers and policymakers in leveraging advanced analytics for climate change mitigation strategies

Abstract

PT Dyandra Promosindo is a company that operates in the event organizer sector, when carrying out their daily business processes they will always be in contact with important information from their clients. Therefore, it is necessary to carry out a risk assessment to avoid loss of confidentiality, integrity and availability of an information asset. The author wants to know how big the risk impact that threatens the security of information assets and provide control recommendations over these assets. The risk assessment process can be divided into three stages, namely, risk identification through interviews and document review, risk analysis using asset valuation and vulnerability and threat ratings, and finally risk evaluation using risk impact measurements. The results of this research showed that 10 critical information assets were identified and only 1 was in the Tolerable risk mitigation group where the other assets were in the Acceptable group. Recommendations for controls for PT Dyandra Promosindo information assets risk based on Annex A ISO/IEC 27001:2022 show 15 controls consisting of 4 Organizational control, 5 People control, 1 Physical control, and 5 Technological control

Abstract

The application of interactive media and the use of technology in supporting learning activities in schools is very important, but based on the initial interview with the Head of High School, YPK Tabernakel Nabire Central Papua, through the telephone in WA, the application of interactive learning media has not been thoroughly done. There are some obstacles, such as insufficient facilities, and not all teachers implement interactive learning media, resulting in a lack of interest among students in following the learning process. Based on this, the study aims to look at the use of Marvel as an interactive learning media to increase the interest of students in high school at YPK Tabernakel Nabire Central Papua, especially in class X MIA I. The research uses qualitative methods and purposive sampling techniques. The collected data will then be analyzed using one of the data analysis techniques of the Creswell Model. Based on the results of the observations and interviews, it is concluded that the interactive media of Marvel can increase the student's interest in learning, as seen from the indicators of the observation results and the source's answers during the interview.

Abstract

Every company that has employees who sare not gathered in one place must want speed and efficiency for good information exchange. To elevate quality of company management, it is essential to understand the shortcomings of the employees management. Pelita Mas Otobus Company is a bus company based in Malang City, East Java, which conducts its management system still running conventionally. This has shortcomings in terms of efficiency and accuracy of data on information exchange between employees. From the existing issue, it is important to redesign the business processes at Pelita Mas Bus Company by applying BPR (Business Process Reengineering). BPR is a strategy aimed at redesigning deficient business processes to improve their efficiency. The research begins with data collection, involving observations, process identification, case studies, interviews with Pelita Mas Bus Company, and relevant literature review. Mapping a business process using the ASME (American Society of Mechanical Engineers) standard process map. Utilizing the ASME standard process map, the business process performance is assessed through the throughput efficiency test. Subsequently, the focus shifts towards enhancing and refining the business process redesign to make it more efficient. The ultimate outcome of this study is the redesign of the business process

Abstract

Managing drug supplies is very important because it minimizes drug losses in institutions such as health centers, pharmacies and hospitals, so that drugs of any type are in accordance with the quantity needed. The research aims at grouped drug data, where this case study was carried out at the Curug Health Center UPTD which will be used as a guide in submitting a drug import plan at this health center. The data processed in this research is the 2022 annual report, drug needs plan and proposed drug needs (RKO 2023) at the Curug Health Center UPTD. The data in this research was processed by the K-Means algorithm with the rapidminer tool, where this technique data is grouped by collecting data into clusters. The results obtained were that Cluster 0 was a very low cluster which contained 14 drug items, then Cluster 1 with 12 drug items was a low cluster, Cluster 3 with 2 drug items was a high cluster and Cluster 2 was the highest cluster with 2 items drug.
