Abstract

Commercial mayonnaise currently available is full fat mayonnaise with high oil content (70-80%) which can be harmful to health when consumed in the long time. Reduced fat mayonnaise (RFM) as an alternative mayonnaise, which reduces the oil content causes the emulsion changes so a stabilizer is needed. The stabilizer that can be used is porang flour which rich in glucomannan. This study aimed to determine the physicochemical and sensory of RFM with variations in oil (M) (40%, 50%, and 60%) and porang flour concentration (P) (0.1%, 0.2%, and 0.3%). This study used a Completely Randomized Design. Physicochemical parameters include water content, ash content, fat content, protein content, pH, viscosity, emulsion stability, color and emulsion droplets. The result showed that RFM has water content content 26,14 - 44,25%, ash content 0,52% - 0,60%, fat content 37,61% - 64,11%, protein content 3,35% - 3,76%, pH 4,07 - 4,17, viscosity 639,90 cP - 9250,00 cP, emulsion stability 99,98% - 100%, and color L* 83,92 - 85,72, a* 2,67 - 5,92, b* 20,28 - 29,25, and chroma 20,75 - 29,48. M2P3 was the selected formulation with higher acceptance for parameters such as color, aroma, texture, taste, and overall compared to the control mayonnaise.

Abstract

This paper presents a hardware inference accelerator architecture of quantized deep neural networks (DNN). The proposed accelerator implements all computation in a quantize version of DNN including linear transformations like matrix multiplications, nonlinear activation functions such as ReLU, quantization and dequantization operation. The hardware accelerator of quantized DNN consists of matrix multiplication core which is implemented in systolic array architecture, and the QDR core for computing the operation of quantization, dequantization, and ReLU. This proposed hardware architecture is implemented in Verilog Hardware Description Language (HDL) code using modelsim. To validate, we simulated the quantized DNN using Python programming language and compared the results with our proposed hardware accelerator. The result of this comparison shows a very slight difference, confirming the validity of our quantized DNN hardware accelerator.

Abstract

XYZ Sugar Factory is a manufacturing company that produces processed sugar cane with the main product being white crystal sugar of the Super High Sugar (SHS) type. The problem found at the XYZ Sugar Factory was that there were defects in white crystal sugar products amounting to 7,359.1 tons with a defect percentage of 11.12%. This study aims to determine the types and causes of defects, as well as suggestions for improvements. The methods used are Fault Tree Analysis and Failure Mode and Effect Analysis. The results of the research show that the types of defects that occur in white crystal sugar products are sugar color defects and sugar grain size defects. One of the causes of sugar color defects is excessive levels of additional raw materials, while one of the causes of sugar grain size defects is the insufficient cooking duration of the sugar crystals. The results of FMEA calculations obtained the highest RPN value, namely sugar color defects with an RPN value of 140 and then grain size defects with an RPN value of 120. Proposed improvements for the company are to make appropriate measurements for additional raw materials to help with the production process and provide more routine training to employees regarding the use of machines. production.

Abstract

The rapid evolution of technology has reshaped the educational landscape, ushering in ubiquitous learning environments that provide learners with unparalleled access to educational resources at any time and location. This study aimed to investigate the impact of delayed feedback on student engagement and problem-solving skills in ubiquitous learning programming environments. The purpose was to understand how different forms of student engagement—behavioral, emotional, and cognitive—influence problem-solving abilities and how students perceive and handle delayed feedback. A quantitative method was employed using a cross-sectional survey design. Data were collected from 293 students enrolled in the Department of Informatics and Computer Engineering, Faculty of Engineering, Makassar State University, who had studied web and mobile programming courses. Standardized questionnaires were administered to measure variables. Quantitative data analysis involved descriptive statistical analysis and structural equation modeling (SEM) using SmartPLS 4.0. The research results revealed that behavioral engagement (BE) significantly improves problem-solving skills and helps students better handle delayed feedback. Emotional engagement (EE) has the strongest influence on problem-solving abilities and responses to delayed feedback. Cognitive engagement (CE), while not directly enhancing problem-solving skills, significantly aids in the management of delayed feedback. These findings underscore the importance of fostering behavioral and emotional engagement to enhance problem-solving skills and mitigate the adverse effects of delayed feedback. Strategies such as gamification, real-time collaboration, and immediate feedback mechanisms are essential to improve learning outcomes in ubiquitous learning programming environments.
