Authors: Ihsani Ulynnuha Aulia , Siswono Tatag Yuli Eko
Published: August 2024

This study aims to understand the metacognition processes of students in solving math problems with the assistance of Chat-GPT using a qualitative method and a case study approach. The research subjects are two eighth-grade students from a junior high school in Surabaya, selected through purposive sampling, with one subject representing successful students and the other representing unsuccessful students in the initial problem-solving test (PST). Data were collected through the initial PST, Chat-GPT-assisted PST, and interviews, then analyzed using metacognitive indicators: planning, monitoring, and evaluation. The successful subject actively engaged with Chat-GPT's answers, using metacognition processes to rethink their understanding, connect with prior knowledge, consider strategies, check steps, adjust errors, and verify solutions. Their errors stemmed from misunderstandings and incorrect information from Chat-GPT, but they adjusted and corrected their work upon prompt. In contrast, the unsuccessful subject only showed metacognitive engagement at the planning stage, struggling to understand the problem and prerequisite algebra material. They relied solely on Chat-GPT's answers without understanding or evaluating them, leading to ineffective problem-solving. The difference in metacognition processes between the subjects was attributed to cognitive factors, such as information received from Chat-GPT's answers, understanding of prerequisite material, and ability to comprehend the mathematical problem

Authors: Anugrawan Kevin , Rosyidi Abdul Haris
Published: August 2024

Analogical reasoning is a process of identifying two problems that aim to produce knowledge by associating relevant concepts and facts and adapting them so that they can solve more complex problems. Low surface similarity does not play a significant role in solving analogical reasoning. This type of research was carried out descriptively with qualitative methods with the aim of describing students' reasoning in solving analogy problems with low surface similarity. The research was conducted at one of the junior high schools in Sidoarjo with three selected students. Research data were analyzed using indicators that had been made by researchers. The data from the research results gave rise to three students who have uniqueness in analogical reasoning. There are two peculiarities found, namely the peculiarities with general cases and the peculiarities with special cases. The low surface similarity in analogy problems has an impact on students in the form of different stages of analogical reasoning that are passed by the three students. Students with general characteristics have stages of linear analogy reasoning. Students with special case characteristics have dynamic analogical reasoning stages. Identifying is done by students by identifying characteristics and concluding the relationship between the two problems. Mapping is done by students by mapping information related to analogy problems. At the time of applying the answers to the source problem to the target problem, there were two students with special characteristics who returned to the previous stage because they found it difficult. Verifying has been done by each student, but students with special cases have beliefs that are contrary to the results of the answers. So, the use of source problems and target problems that have low surface similarities can be used with the condition that the structure of the answers between the two problems must be analogous to each other.

Este ensayo académico examina el impacto de las redes sociales académicas e identifica las inquietudes actuales sobre su uso en el ámbito de la investigación científica. Las redes sociales académicas surgieron como respuesta a las limitaciones de la comunicación científica convencional y se adaptaron a las necesidades actuales de la comunidad académica. Las principales redes sociales académicas son ResearchGate, Academia.edu y Mendeley. Las tres comparten características enfocadas a la comunidad científica y también han mostrado un crecimiento sustancial en cuanto a su número de usuarios. Las ventajas en el uso de estas plataformas son encontrar contenidos científicos, compartir las investigaciones realizadas y crear grupos de colaboración. Como limitaciones y preocupaciones se encuentran las relacionadas con la privacidad, la seguridad y la desorientación de las actividades de investigación, que podrían repercutir en la calidad de las investigaciones y en la esencia de la labor científica. Como investigaciones futuras, se propone analizar la aplicación de políticas para la utilización de las redes sociales académicas en diversos ámbitos, así como estudios sobre la evaluación de estas plataformas a lo largo del tiempo. Además, buscar su eficaz adecuación a las prácticas y principios de la Ciencia Abierta.

Published: August 2024

PT. XYZ is a company that focuses on exporting marine products, especially products for surimi products, PT. XYZ experienced problems in cold chain system activities such as declining quality of fish raw materials, limited cold storage capacity, diversity of supply quality and the risk of overloud storage, resulting in the inhibition of cold chain system activities. The purpose of this study is to identify the causes and provide appropriate mitigation strategies so that risks can be minimized by the Company. This study uses an integration method between ANP and FMEA, so that a WRPN (Weighted Risk Priority Number) value can be produced. Based on the results of the analysis using the integration of the two methods, WRPN was obtained with the highest priority on quality risk factors of 170.713 and storage risk factors of 153.087 so that both risk factors are classified as high risk and need to be mitigated. The mitigation measures provided include separation of contaminated fish, monitoring, microbiological testing, compliance with standards, SOP training, cold storage maintenance, cold storage forecasting, using the FIFO method, supervision of the use of cold storage.

Blood Clam (Anadara granosa) contains high calcium carbonate which can be utilized in various fields by being used as nanotechnology. The shell contains 98.7% CaCO3 making it a sustainable material source. The research aims to synthesize and characterize of calcium oxide nanoparticles by precipitation methods. This method begins with crushing the shell into 100 mesh as sample. Each sample is mixed with HCl solute. After mixing, each filtrate is precipitated with KOH solute to multiple pH (7 ; 9 ; 11). The method continues with neutralizing the precipitate with water until it reach pH 7 and drying it with oven in 100oC for 1 hour. The sample will be calcinated for 3 hours in various temperature (300oC ; 500oC ; 900oC). Samples will be analyzed with SEM-EDX and XRF Analysis. Research indicates that The degree of acidity and calcination temperature do not have a significant effect on calcium oxide content. The calcium oxide content is ranged between 82,58% - 87,47% with the sizes being ranged between 550 nm - 20mm.

One of the common causes of infant death is infectious diseases which can be prevented by immunization also called PD3I (diseases that can be prevented by immunization). The three domains of behavior knowledge, attitude, and action, play a big role in mothers completing their child’s immunization status to fulfill immunization coverage by a minimum of 80%, according to the Universal Child Immunization (UCI) standards. Successful immunization coverage is believed to help achieve the highest level of public health. The purpose of this research is to identify the relationship between maternal knowledge, attitude, and action toward basic immunization and the basic immunization status of children at Permata Depok Hospital in 2023 for further improvement of immunization coverage and reduce infant mortality rates. This research is an analytical survey with a cross-sectional approach. The research population was mothers of toddler patients at Permata Depok Hospital who visited on the recruitment day and met the inclusion criteria using consecutive sampling techniques. The sample size in this study was 52 participants. The Chi-Square statistical test was used in bivariate data analysis with a confidence level of 95% (α=5%). Based on the research results, it was found that there was a significant relationship between maternal knowledge and the child's basic immunization status (p=0,010), there is a significant relationship between the maternal attitude and the child's basic immunization status (p=0,006), there is also a significant relationship between the maternal action regarding basic immunization and the child's basic immunization status (p=,0001).
