Dhimas Fajarwibowo — 2024-03-31

Trends in interior design, modern lifestyles, and increasing consumer awareness about the beauty and comfort of the home have driven the ever-increasing demand for quality furniture products. In this context, furniture companies are required to not only produce attractive products but also provide superior and personal service to customers. To overcome various challenges in the furniture industry, this research developed a CRM-based furniture sales application on the Android platform. The application is expected to be a solution to improve service to customers. The features provided include displaying furniture stock info along with prices, search features, furniture ordering features, transactions, purchase history, features for analyzing customer preferences based on product type criteria, and shipping. The methods used include literature studies, site surveys where the application will be used, needs analysis, application design, application development, implementation, and testing. The results of functionality testing show that the application has functioned as expected.

Prediksi Penjualan HT Motorola XiR C2660 Menggunakan Algoritma Support Vector Regression (Studi Kasus: CV. Alfacoms)

Wildwina — 2024-03-31

In carrying out a business that operates in the field of selling goods, predictions are very necessary. Predictions are very necessary because making predictions can help predict what will happen in the future so that the risks that will occur can be minimized as small as possible. This research focuses on sales predictions in 2023 for the HT Motorola XiR C2660 brand using the SVR (support vector regression) algorithm and using linear type kernel parameter testing and c(cost) with a test value of 0.1. To obtain parameter types and parameter test values, use the GridSearchCV technique. Apart from that, this research uses error value testing with mean absolute percentage error (MAPE). So the results of the HT Motorola XiR C2660 sales prediction for 2023 with the SVR algorithm were obtained. In 2023, 209 units were sold with an error value of 11.23%, which means the forecasting ability with the SVR algorithm is good.

Sistem Pakar Kerusakan Mesin Kopi Espresso Lamarzocco di Kopi Daripada dengan Metode Forward Chaining

Rizal — 2024-03-31

Each tool and part contained in a coffee maker has its own level of importance and may not function optimally. This problem often becomes a problem for users or bartenders on duty at work. To overcome this problem, this can be done by someone who has basic knowledge of Lamarzocco coffee makers. However, sometimes these problems also require a high level of expertise from the components so that special technicians are needed to repair them. How to design an expert system application with the forward chaining method to diagnose failures in Lamarzocco coffee machines. In this research the author used the PHP programming language and MySQL database. The research method used by the author is data collection, analysis and object-oriented programming. The program can then be accessed on the website for ease of use, which will then be black box tested with the manager or supervisor of the relevant point of sale. The results of research on the design and application of an expert system using the forward chaining method can diagnose damage to an espresso coffee maker (Lamarzocco coffee maker), this expert system application can be used to assist employees in handling damage to a Lamarzocco espresso machine very well without any problems occurring, and From the results of trials using black box testing on the Lamarzocco coffee machine damage expert system application, we got good results

Pengujian Algoritma Inception V3 dalam Mengidentifikasi Penyakit Tuberculosis dan Pneumonia

Alvin Widyadhana Kosman — 2024-03-31

According to the World Health Organization (WHO), Tuberculosis and Pneumonia are two of the 10 biggest causes of death in the world. To reduce the risk of contracting both diseases, early and accurate diagnosis is needed. One way to achieve early and accurate diagnosis is to integrate image processing into the diagnosis process. The aim of this research is to test the CNN Inception V3 algorithm in identifying a case of Tuberculosis and Pneumonia disease by using a photo of electromagnetic radiation from a person's body wavelength. From the photos, the results obtained were the percentage of accuracy of x-ray photos of normal lungs is 99.63%, the percentage of accuracy of x-ray photos of tuberculosis lungs is 99.82% and the percentage of accuracy of x-ray photos of lungs with pneumonia is 99.69%.

Analisis Kebutuhan Arsitektur dan Desain Antarmuka Sistem Manajemen Risiko Berbasis Penelitian House of Risk pada Institusi Pendidikan

Intan Dzikria — 2024-03-31

Risk management in educational institutions plays an important role because the educational environment will always change and become increasingly complex. Risk management can provide support to educational institutions to identify, assess and manage risks in a systematic and structured way. House of Risk (HOR) is an approach used to manage risk and focuses on formulating preventive actions and handling the causes of risk, by combining FMEA and HOQ principles. This research aims to design an architectural requirements analysis and risk management system interface design using the design thinking stages. This research produces an architectural design, software requirements, and interface design for a higher education risk management system. The user interface design was tested using usability testing with a score of 87.5, which shows that the interface design is useful for various system actors. The results of this research can be a reference for further research in implementing the creation of a HOR-based risk management system in web-based educational institutions.
