Abstract

Lesson Study is an approach to improving the quality of learning carried out by teachers collaboratively, with the main steps of designing learning to achieve goals, implementing learning, observing the implementation of the learning, and reflecting to discuss the learning studied and improve it and plan the next lesson. The main focus of implementing lesson study is student activities in class, with the assumption that student activities are related to teacher activities while teaching in class. In implementing PPL Education at UNTAD, the implementation of Lesson Study is integrated with the implementation of clinical supervision. The aim is to improve the quality of student learning outcomes and learning products. However, what is still experienced by the world of education today is that more than 50% of teachers do not understand and pay less attention to achieving and improving pedagogical and professional competence, including in schools in Palu City. To teach teachers to implement LS, it is not enough if teachers are introduced to what and how to implement it, but they also need to be introduced to why, what the long-term and short-term goals of implementation are. Teachers also need to be introduced to what the requirements are, what the difficulties and obstacles are in implementation, and that the main requirement for implementation is a commitment to benefit the nation's children. One of the critical characteristics of intelligent humans is that they not only know something but also how to respond and act on it.AbstrakLesson Study merupakan suatu pendekatan peningkatan kualitas pembelajaran yang dilaksanakan oleh guru secara kolaboratif, dengan langkah-langkah pokok merancang pembelajaran untuk mencapai tujuan, melaksanakan pembelajaran, mengamati pelaksanaan pembelajaran tersebut, serta melakukan refleksi untuk mendisukusikan pembelajaran yang dikaji tersebut dan menyempurkannya dan merencanakan pembelajaran berikutnya. Fokus utama pelaksanaan Lesson Study adalah aktivitas siswa di kelas, dengan asumsi bahwa aktivitas siswa tersebut terkait dengan aktivitas guru selama mengajar di kelas. Dalam penyelenggaraan PPL Kependidikan di UNTAD, penerapan Lesson Study diintegrasikan dengan penerapan supervisi klinis. Tujuannya untuk meningkatkan kualitas hasil belajar dan produk belajar siswa. Namun yang masih dialami oleh dunia pendidikan sampai saat ini adalah lebih besar 50% guru yang kurang memahami dan kurang memperhatikan pencapaian dan peningkatan kompetensi pedagogik dan professional, termasuk di sekolah-sekolah yang ada di Kota Palu. Untuk membelajarkan guru melaksanakan LS tidak cukup bila guru dikenalkan pada apa dan bagaimana melaksanakannya, tetapi juga perlu dikenalkan mengapa, apa tujuan jangka panjang dan jangka pendek pelaksanaan. Guru juga perlu dikenalkan pada apa persyaratannya, apa kesulitan dan hambatan pelaksanannya, dan bahwa persyaratan utama pelaksanannya adalah adanya komitmen untuk memaslahatkan anak bangsa. Salah satu ciri kritis manusia cerdas yakni tidak hanya mengetahui sesuatu tetapi juga bagaimana menanggapi dan menindaklanjutinya.

Abstract

Stunted growth remains a critical public health concern, particularly in developing regions. This study investigates the potential of active compounds derived from Sauropus androgynus as dietary supplements for preventing growth stunting, employing a network pharmacology approach. Fifteen phytochemicals were analyzed, leading to the identification of 11 growth-related target proteins. Among them, protein tyrosine phosphatase nonreceptor type 11 (PTPN11) emerged as a key regulatory protein related to cell growth, as determined by protein-protein interaction network analysis. Functional enrichment and pathway analyses further highlighted the relevance of these targets in growth-related mechanisms. Molecular docking was performed to investigate the molecular interactions between the active compounds of S. androgynous and PTPN11. The findings revealed that all compounds could form a complex at the active site of PTPN11. Furthermore, the top five ligands were subjected to MD simulation to evaluate the structural stability of all complexes. Among them, only two lead compounds, such as paeonol and phenylacetaldehyde, are stable in complex with PTPN11 during simulation. The findings suggest that S. androgynus contains promising active compounds that may serve as functional food supplements for preventing stunted growth, highlighting their potential role in improving child growth outcomes among at-risk populations.

Abstract

Yogurt is a fermented milk product produced by Lactobacillus bulgaricus and Streptococcus thermophilus, which confer a distinctive sour taste. Lactic acid bacteria require a carbohydrate source during growth, which can be obtained from purple sweet potatoes. This study aimed to determine the effect of fermentation time on carbohydrate and protein levels in purple sweet potato yoghurt. This study comprises 3 samples: sample A (yoghurt fermented for 7 hours), sample B (yoghurt fermented for 14 hours), and sample C (yoghurt fermented for 21 hours). The study employed a quantitative design, with carbohydrate testing using the Luff-Schoorl method and protein testing using the Kjeldahl method. The carbohydrate content was 10.36% in sample A, 10.41% in sample B, and 10.02% in sample C; the protein content was 2.23% in sample A, 3.93% in sample B, and 4,03% in sample C.

Abstract

Banana tape is one of the innovations in processing bananas into new processed products that can be enjoyed by the community, which is almost the same as making tape in general. The purpose of this study was to determine the right variation of ragi concentration on the physical and chemical characteristics of kepok banana tape. This type of research is experimental with the Completely Randomized Design (RAL) method with variations in ragi concentration, namely 0.5 grams, 1 gram, 1.5 grams, 2 grams and 2.5 grams with a fermetation time of 3 days. The parameters of this study include physical analysis (taste, flavor, color and texture) and chemical analysis (glucose, alcohol and pH). The results showed that ragi concentration of 0.5 gram produced the best organoleptic test of taste 3.75, aroma 3.4, color 3.6 and texture 3.45. Chemical tests showed that a ragi concentration of 1.5 grams produced the best results in glucose levels of 7.9%, alcohol 1.24% and pH 4.41. This study has the potential to be used as a contextual chemistry learning medium, particularly in understanding fermentation processes, pH changes, and biochemical transformations in everyday food products.

Abstract

Ketapang seed tempeh (Terminalia catappa) is made from ketapang seed waste through a fermentation process using Rhizopus sp., as with soybean tempeh. This study used a quantitative descriptive method to determine the content of primary metabolites, including fat, protein, and carbohydrates. Laboratory analysis was conducted at the Chemistry Education Laboratory, Tadulako University, using the Soxhlet method for fat, the Kjeldahl method for protein, and the phenol-sulfur method for carbohydrates, as well as organoleptic tests by 15 panellists. The results showed that ketapang seed tempeh had very low fat content (0.1714%), low protein (0.0189 g per 100 g sample), and moderate carbohydrate (10.06%). Fried ketapang tempeh was preferred by the panellists, although its acceptance level was still lower than that of soybean tempeh. The novelty of this study lies in the quantitative evaluation of primary metabolites in tempeh made entirely from ketapang seeds, which has not been previously reported. These findings indicate that ketapang seeds have the potential to serve as an alternative ingredient in the production of low-fat tempeh.

Abstract

Background: Students’ mathematical reasoning is often limited by their difficulty in linking abstract mathematical concepts with meaningful real-life contexts. In many classrooms, mathematics is perceived as disconnected from students’ sociocultural experiences, which can hinder the development of deeper reasoning processes. Aims: This study aims to profile students’ mathematical reasoning abilities within the Alkhairaat sociocultural context and to examine how contextual integration influences reasoning across different ability levels. Method: A sequential explanatory mixed-methods design was employed involving 33 eighth-grade students in a madrasah. Quantitative data were collected through a mathematical reasoning test embedded in the Alkhairaat context and analyzed using the Rasch measurement model (Ministep 5.10.4.0) to evaluate the instrument’s psychometric quality and map students’ reasoning abilities. Qualitative data were then obtained through clinical interviews to explore students’ cognitive processes when solving contextual problems. Results: Rasch analysis indicated acceptable psychometric properties, with item reliability of 0.67 and person reliability of 0.58. Wright Map analysis categorized students into three ability levels: high (12.12%), medium (66.67%), and low (21.21%). The findings show that the Alkhairaat context functions differently across ability levels: as a cognitive tool for abstraction among high-ability students, as procedural scaffolding for medium-ability students, and primarily as an affective anchor for low-ability students. Conclusion: Integrating sociocultural contexts such as Alkhairaat values can support mathematical reasoning by providing meaningful entry points for abstraction. However, its effectiveness depends on students’ initial proficiency, indicating the need for additional instructional support for lower-ability learners.
