No full textAs an archipelagic nation, ships are essential for maritime transportation. Currently, almost all ships use 2-stroke or 4-stroke diesel engines as their main engines due to their advantages over other engine types. Diesel engines generate power through a fuel combustion system called an internal combustion engine (ICE). ICE motors are one of the most common types of motors used on ships due to their substantial power output as prime movers. However, changes in load will cause the motor speed to change, affecting the ship's power output. To regulate the speed of an ICE motor, a control system and various types of controllers are required, including fuzzy logic methods. This research aims to develop a fuzzy logic-based control system for ICE motor speed control on a trimaran vessel. The design of ICE motor speed control on ships using the Fuzzy Logic method is very suitable for controlling non-linear systems. The controller is implemented on an STM32 microcontroller to regulate the ICE motor. The control performance shows very stable and efficient results in various wave conditions, with stability in meeting the set point. The Fuzzy Logic method has proven effective in maintaining RPM and fuel consumption. Tests show that the components used have good accuracy with an average error of less than 5%, and the control system is more stable than without control
Analysis of Metacognitive Failures when Using ChatGPT in Solving Mathematical Problems: An Islamic Educational Perspective
Get PDFMathematics contributes significantly to the advancement of various fields of science, knowledge, and technology. In today’s digital transformation era, technology plays an essential role in shaping the way students think and learn. One of the most influential technological innovations in education is artificial intelligence (AI), exemplified by ChatGPT. However, the ease of accessing solutions through AI may reduce students’ awareness of their own thinking processes and lead to a decline in independent reasoning. Therefore, this study aims to analyze metacognitive failures among first-year university students when using ChatGPT to solve mathematical problems through an Islamic educational lens. From an Islamic perspective, thinking (tafakkur) and reflection (tadabbur) are acts of worship that cultivate intellectual and spiritual awareness. Islam emphasizes the responsible use of knowledge and technology, guiding learners to maintain amanah (intellectual honesty), avoid ghurur (deceptive dependence), and practice muhasabah (self- reflection) in the pursuit of understanding. Metacognition, in this sense, extends beyond cognitive control to include moral and spiritual accountability before Allah. This study employs a qualitative approach with a descriptive exploratory design. The instruments used include mathematical problem-solving tests, MAI (Metacognitive Awareness Inventory) questionnaires, and open-ended interviews. The research stages consist of identifying the problem, determining the focus of the study, specifying data needs, collecting data, and analyzing data. The results reveal that three participants experienced distinct forms of metacognitive failure: S1 experienced metacognitive blindness, S2 experienced metacognitive vandalism, and S3 experienced metacognitive mirage, as they perceived warning signs that were not actually present. Viewed through Islamic education, these failures illustrate an imbalance between rational and spiritual awareness. Overreliance on AI tools without critical reflection may weaken ijtihad (independent reasoning) and hinder sincere learning (ikhlas). Therefore, integrating Islamic values such as tawakkul (trust in Allah after effort) and amanah ilmiyyah (intellectual integrity) can help students use technology ethically and purposefully in their quest for knowledge

This study aims to determine the effect of various concentrations of colchicine on yield and changes in stomata characteristics of sweet corn (Zea mays L. saccharata) Paragon variety. Yield and quality of corn plants D4 treatment (600 ppm) is the best treatment for yield parameters and quality of corn plants, on the characteristics of the stomata of corn plant leaves the D4 treatment (600 ppm) is a good treatment for the parameters of length, width, and area of stomata sweet corn plant leave
The Effect of Washing Treatments and Natural Adsorbent Application to the Quality of Fresh Cassava (Manihot utilissima)
Get PDFA research to know the influence of washing treatments and various natural adsorbent as storage media of fresh cassava has been done in Agriculture laboratory of the University of Islam Malang. The research was done using 2 factors (washing treatment and of natural adsorbents). The first factor consisted of 2 levels: no washing and washing treatment. The second factor consisted of 5 levels (without natural absorbent, river sand, charcoal husk, wood charcoal, and ashes). The storage was done for 2 weeks. The parameters observed were weight loss (%), moisture content (%), total soluble solid, total microbes, and sensory test (colour, aroma, and taste of the cassava). The result showed that quantitatively the cassava stored in the river sand without water treatment gave the best performance. It had the highest water content (33,40%) at the last observed (2 weeks storage). Respondents liked the cassavas which were stored in the river sand as adsorbent media. Further research using river sand l as the natural adsorbent in cassava storage should be done accurately to know the effect of the adsorbent to the nutrition change and economic value of the storage system
Would you be willing to pay more if AI robot waiters were introduced? The pivotal role of the need for uniqueness and perceived uniqueness
Get PDFService robots have the potential to enhance customer experiences with their innovative technology, but many people still feel uncomfortable around them. While some customers are open to being served by robots, most still prefer interacting with humans. This inconsistency highlights the need to explore why consumers choose robotic service restaurants over conventional ones. This study aims to extend the existing literature by examining the need for uniqueness and perceived uniqueness as critical determinants of attitudes and willingness to pay more. To the best of the author's knowledge, there are few studies that explore these factors in the context of service robots, particularly in Indonesia. We surveyed 308 customers who dined at restaurants with robot waiters. Our analysis, using regression and Sobel, revealed that the need for uniqueness doesn't significantly affect how consumers feel about these restaurants or their willingness to pay more. However, perceived uniqueness positively affects both consumer attitudes and willingness to pay more, both directly and indirectly. This means that while the need for uniqueness can motivate consumers to explore novel experiences like dining at a restaurant with robot waiters, restaurants must ensure that the overall experience meets or exceeds customer expectations to enhance positive attitudes and willingness to pay more
