  • The Determination of the Fuzzy Membership Sets for a Hybrid Coffee Bean Dryer Temperature Controller

    Authors: Yusrila Kerlooza; Ari Ramadhani

    DOI: 10.1109/INCITEST59455.2023.10396975

    Abstract

    Traditionally in Indonesia, post-harvest processing of coffee beans is usually done by drying them in the sun. This method will produce coffee beans with uncertain quality. The use of sophisticated industrial-scale dryers is not easy to implement in rural areas due to the limited supply of electricity or gas as a source of heating energy. In this paper we present the design of a coffee bean dryer temperature controller using the fuzzy logic method. This device can regulate the temperature inside the drying chamber by adjusting the opening size of the hot air valve without changing the amount of heat supply from the heating components. In this way, various heat sources can be used according to their availability in the field. This research tested several fuzzy membership function scenarios in the form of several variations of valve opening sizes and measured the speed and stability of each variation in reaching the desired temperature. Based on the dryer model developed in this study, the most stable control scenario at the ideal coffee bean drying temperature is the fuzzy control scenario with 5 membership functions. The fastest time from 28°C to reach a temperature set point of 40°C is 10 minutes 26 seconds and the fastest temperature drop from 42°C to the same set point takes 3 minutes 19 seconds. © 2023 IEEE.

    Authors: Diana Effendi ; Rani Puspita  Dhaniawaty ; Mufti Muhammad Pratadina ; Rahmat Hidayat ; Muhammad Alghani ; Bella Hardiyana

    DOI: 10.1109/INCITEST64888.2024.11121459

    Abstract:

    This research aims to build a multimedia-based learning application program for the history of a colonial war in Indonesia. The object of research was conducted at SMAN 24 Bandung, class XI as many as 8 classes. The problem faced at this time is that students get material on the history of war in Indonesia only by capitalizing on materials from books and or PowerPoint soft files as references. In delivering the material by the teacher only face to face in class, lecturing, holding question and answer sessions, and not having a variety of interactive learning media, learning history becomes less interesting. Multimedia is an innovative learning system that requires teachers to be more creative in combining multimedia elements such as text, images, sound, video, and animation to unite and achieve learning objectives. The method used in developing this application is the Multimedia Development Life Cycle (MDLC). In the alpha and beta testing stages, testing was carried out by 4 evaluators, namely learning material experts (vice principal), learning design experts and communication media experts from multimedia industry practitioners, and users represented by history teaching teachers. Three aspects are assessed, namely audio media, video media, and multimedia with a value > =3, multimedia applications are said to be suitable for use as learning aids. From the results of the evaluator’s assessment, the three aspects are obtained around the average value of the evaluator 5.18, which means that this application is feasible to use as a learning media in the history of colonial wars in Indonesia. © 2024 IEEE.

  • Comparison of K-Nearest Neighbor and Multiple Linear Regression for Beauty Product Sales Prediction

    Authors: Ade Ismayani Rahman, Rahma Wahdiniwaty

    DOI: 10.1109/INCITEST64888.2024.11121461

    Abstract

    Sales predictions constitute a critical component in establishing and expanding a business entity. Accurate sales projections enhance the quality of decisionmaking processes, increase profitability, and improve customer service results. The main objective of this research is to assess the efficacy of K-Nearest Neighbor and Multiple Linear Regression methodologies in predicting beauty product sales. The methodological approach employed in this research is of a quantitative method. The dataset incorporated encompasses variables such as product specifications, pricing, stock, and number of sold. Data preprocessing methodologies are employed to clean the data, handle missing data and detect outliers. The research findings show that both methods can predict product sales. However, the Multiple Linear Regression model has a better advantage than K-Nearest Neighbor. The Multiple Linear Regression method has smaller average values of RMSE, MAE, and MAPE than K-Nearest Neighbor, which are 4.637, 3.990 and 0.077. Meanwhile, the average value of R2 generated by Multiple Linear Regression is greater than K-Nearest Neighbor, which is 0.820. This proves that the Multiple Linear Regression method is more suitable for predicting beauty product sales. © 2024 IEEE.

  • Prediction of Raw Material Usage for Hijab Production Using k-Nearest Neighbors and Random Forest Methods

    Authors: Luthfi Rifqi Zulfiqar, Geraldi Catur Pamuji, Hengky Saputra, Fithrah Syawaludin

    DOI: 10.1109/INCITEST64888.2024.11121429

    Abstract

    Accurate demand forecasting will optimize the supply chain management in the hijab industry, since demand forecasting is highly required for maintaining efficient and effective production and inventory processes. This study investigates the k-Nearest Neighbors (k-NN) and Random Forest (RF) for the purpose of predicting demands regarding raw materials in the hijab production process. Key performance metrics considered for evaluating both models include the RMSE, MAE, MAPE, and R2. These findings indicate that k-NN outperforms RF in terms of superior prediction accuracy with K=2. In this respect, the root mean square error from k-NN was 1.768 against the RF’s RMSE of 1.801, proving that it is always more reliable in capturing local variations in data. On top of this, even incomplete data or those occasions when demand shifts all over the place were handled well by k-NN with more consistent and thus more accurate results. These results offer valuable insights for hijab manufacturers, allowing them to optimize their supply chain management by optimizing material shortages and overstock inventory. This research further highlights the importance of choosing the right predictive model according to the context and data characteristics to improve operational efficiency and enhance customer satisfaction. © 2024 IEEE.
