Abstract

A computational thinking approach is an approach to thinking and reasoning by computer scientists. Computational thinking skills can be adopted as an approach to solving a problem and analyzing the solution. The computational thinking approach is not limited to computer science but can also be applied to other disciplines through problem-solving. The computational thinking approach has been integrated into various instruments and learning media. The purpose of this research is to see the potential of the computational thinking approach to be integrated into learning media to improve problem-solving skills and to discuss the integration of computational thinking in various learning tools and media. This research method uses literature studies with 6 international articles as the main source from scopus.com and 19 articles as supporting articles from scholar.google.com. The results of the study show that the computational thinking approach has the potential to be integrated into various learning tools and media as a means of increasing problem-solving skills.

Abstract

Fish crackers are one of the most popular snacks in Southeast Asian countries, including Malaysia. Traditionally, the process of fish crackers drying usually uses sun drying method. The problem of this method is uncontrollable weather conditions. Drying of fish crackers requires an alternative in the drying process. The heat pump is the most effective and controllable alternative dryer in reducing the moisture content of the material. Air Conditioning (AC) is one type of heat pump. The heat produced by the AC condenser can be used to dry fish crackers. In this study, the AC utilization as a heat pump system to dry fish crackers has an Evaporate Capacity (EC) of 1,838kg/h, a Specific Moisture Extraction Rate (SMER) of 1,998kg/kWh, and a Specific Energy Consumption (SEC) of 0.425kWh/kg of dry crackers. This drying machine is also economically feasible because it has an NPV> 0 which is RM28201.58 with an investment period of 1 year.

Abstract

This research aims to determine the influence of cognitive style on students' critical thinking abilities. This research uses a quasi-experimental method with a factorial design research design. The research subjects consisted of class XI MAN 1 Central Lombok students who were divided into experimental classes and control classes. The experimental class uses the PBL model, while the control class uses a conventional learning model. Research instruments include critical thinking ability tests and the Group Embedded Figures Test (GEFT) cognitive style test. Before the critical thinking ability test instrument is given, a test of the instrument is first carried out, namely a validity and reliability test. level of difficulty, and distinguishing power. The research results show that the significant level value is 0.001 which is smaller than α which is equal to 0.05 (0.000<0.05). These findings indicate that there is an influence of cognitive style on students' critical thinking abilities.

Abstract

The review article focuses on the potential of bio-based plasticizers to enhance the mechanical properties of polymer membranes, addressing the critical issues of fragility and brittleness. It highlights the environmental and health risks associated with traditional plasticizers like phthalates and also advocates for the adoption of sustainable and non-toxic bio-based alternatives. In doing so, it emphasizes the significant advancements in bio-based plasticizer research, aiming to stimulate further scientific inquiry into their application in membrane synthesis. By advocating for the adoption of green polymers, the article underscores the critical necessity for the development of environmentally benign and mechanically robust membrane technologies. These advancements hold considerable promise for a wide array of applications, notably within biomedical domains and separation processes, heralding a new era of sustainability and functionality in membrane technology

Abstract

This study aims to describe the profile of student learning outcomes in the affective, cognitive, and psychomotor domains through the application of the Problem Based Learning (PBL) model supported by three-dimensional media and interactive games in grades V and VI of SD Negeri 29 Ampenan. This type of research is a case study with a descriptive approach. Data collection was carried out using observation sheets to assess the affective domain, a final learning test to assess the cognitive domain, and a performance sheet to assess the psychomotor domain. The learning topics include 4 topics, namely Listening to folk tales., Pancasila in my life, Diseases affecting the musculoskeletal system, and Hearing because of sound. The learning implementation was carried out on July 23, 24, 25, and 26, 2024, respectively. The results showed that the application of PBL with three-dimensional media and interactive games had a positive effect on the three domains of learning outcomes. In the affective domain, students showed increased cooperation, responsibility, and discipline. The cognitive domain recorded a good understanding of the learning concept according to the topic. In the psychomotor domain, students were able to complete practice-based tasks with satisfactory results. These findings support the constructivism theory, which emphasizes the importance of hands-on and interactive experiential learning to enhance deep conceptual understanding. This study recommends the use of innovative media such as three-dimensional and interactive games in the PBL model to enhance students' learning outcomes holistically.

Abstract

Research has been done on thin films by mixing TiO2 with cobalt doping and adding HCI as a solar cell material. The aim of this research is to produce a thin layer that is good for use in solar cells. This research has several stages, namely: 1) weighing cobalt and titanium; 2) glass substrate preparation; 3) making a sol-gel solution; 4) thin layer deposition; and 5) heating the sample. From these several stages, the result was that a pure TiO2 solution without doping obtained a thick white solution, whereas the more doping used, the fainter the color of the solution obtained. The thin-layer synthesis process uses a spin-coating method assisted by a modified centrifuge to evenly distribute the sol-gel solution on the surface of the glass substrate
