Abstract

This research aims to provide an influence on the use of Student Worksheets (LKPD) based on Project Based Learning (PBL) on improving 21st century skills in fifth grade elementary school students. The problem raised is the low development of critical thinking, creativity, collaboration and communication skills in students who use conventional learning methods. This research uses quantitative methods with a quasi-experimental design. The research sample consisted of 60 students who were divided into two groups: 30 students in the experimental group who used PBL-based LKPD and 30 students in the control group who used conventional LKPD. The instruments used include skills tests, observation sheets, and student perception questionnaires. Data were analyzed using the t test (t-test). The research results showed that the experimental group experienced a significant increase in critical thinking skills by 18.53%, creativity by 16.82%, collaboration by 19.31%, and communication by 14.21%. Meanwhile, the control group only experienced an increase of 9.11%, 7.62%, 8.43% and 6.71% respectively. In conclusion, PBL-based LKPD is significantly more effective in improving 21st century skills in elementary school students compared to conventional learning methods. These findings support the implementation of PBL as an effective learning strategy at the basic education level.

Abstract

This study aims to identify the differences between saltwater, freshwater, and imitation pearls based on their morphology and topography. Samples were collected from the pearl trading center in Sekarbela, Mataram, Lombok, Nusa Tenggara Barat. The methods employed included physical analysis focusing on origin, formation process, shape, weight, color and light reflection, as well as price. Additionally, morphological and topographical scanning was conducted using Scanning Electron Microscopy (SEM)-EDS to obtain more detailed data. The research findings revealed significant differences among the three types of pearls, particularly in color reflection and luster. Saltwater pearls exhibited the strongest and most radiant color reflection compared to freshwater and imitation. Morphological examination showed pearl grains were irregular in shape and varied in size. Bright colors were predominantly associated with elements having high atomic numbers, whereas dark colors were linked to elements with low atomic numbers. The EDS analysis indicated distinct differences in the chemical composition of each pearl type. Calcium was found to dominate in saltwater pearls, carbon in freshwater pearls, and silicon in imitation. These findings provide deeper insights into the morphological characteristics and chemical compositions of each type of pearl, enhancing the identification of quality differences and the unique traits of each variety.

Abstract

The study explores the potential of utilizing talas tuber flour (Colocasia Esculenta L. Schott) and katuk leaf flour (Sauropus androgynus L. Merr) in biscuit production to enhance nutritional value and promote lactation in breastfeeding mothers. Talas, rich in complex carbohydrates, fiber, minerals, and vitamins, and katuk leaves, high in protein, vitamins A and C, iron, and lactogenic active substances, were used to develop biscuits in three different formulations: F1 (95%: 5%), F2 (90%: 10%), and F3 (85%: 15%). The organoleptic test identified F1 as the best formulation, and proximate analysis showed that F1 contained 6.14% moisture, 2.52% ash, 27.04% fat, 8.59% protein, 50.3% carbohydrates, and 6.70% crude fiber. The biscuits also contained 0.209% phosphorus, 80.4 mg/kg iron (Fe), and 142 mg/kg calcium (Ca). These findings suggest that biscuits made from talas tuber and katuk leaf flour can be a valuable nutritional supplement, potentially aiding in the improvement of breast milk production.

Abstract

Waste is one of the polemic problems that occurs in Indonesia. Almost every region has savings in the form of waste in large amounts and is spread throughout Indonesia. Not a few people do not care about the use of plastic waste which can cause environmental pollution. This study highlights the teaching of microplastic material, a new global environmental problem, in science learning. The novelty lies in the emphasis on topics that are relevant to current environmental conditions and offer innovative learning strategies, such as project-based methods, experiments, and digital technology, to improve students' understanding. This research aims to analyze science learning strategies in integration with microplastics. The method used in this research is a literature review using the PRISMA approach. The data source was taken from Sinta 1-3 via the Google search engine over the last 6 years. The results of the review found that the learning model most frequently used as Problem Based Learning (PBL), then the second most frequently used was the Guided Inquiry model. These two learning models are often used because they are most relevant to the nature and complexity of environmental problems, while the learning model that is rarely used is the Discovery Learning model because this model gives students the freedom to find information independently so that if students are not guided it will cause unnecessary misunderstandings. adequate regarding environmental pollution problems.

Abstract

One of the genetic improvement efforts to improve the performance of Bali cattle offspring production is crossbreeding Bali cattle with exotic bulls. This study aimed to identify markers of body size and shape of Bali cattle and its crosses with exotic bulls using principal component analysis. The materials used in this study were 91 heads of Bali, Simbal, Brahmbal, Limbal, and Pobal cattle, consisting of 34 males and 57 females. The variables observed were body measurements (morphometrics) consisting of shoulder height, body length, chest circumference, chest depth, chest width, hip height, and hip width. Data analysis used Principal Component Analysis in the Minitab Release 19 statistical application. The results showed that Bali, Simbal, Brahmbal, Limbal, and Pobal male cattle had the same body size markers, namely chest circumference. The body shape markers of male cattle are hip height for Bali cattle, chest length for Simbal and Pobal cattle, chest depth for Brahmbal cattle, and hip width for Limbal cattle. The body shape markers in female cattle are body length for Bali, Simbal, Brahmbal, and Pobal cattle, and hip height for Limbal cattle. These body size and shape markers have a strong correlation with the first principal component and the second principal component, so they can be used as selection criteria to improve the production performance of Bali and Bali crossbred cattle.

Abstract

Innovative learning models are essential to enhance students' cognitive abilities and address misconceptions in physics learning. This study aims to provide an overview of the influence of implementing the Synectics learning model with mind mapping assignments on the quantity of misconceptions and the cognitive learning outcomes of senior high school students. The research employed a quasi-experimental method using a randomized control group pretest-posttest design. The study was conducted on 11th-grade students at a senior high school in Palu, Central Sulawesi, during the 2023/2024 academic year. A cluster random sampling technique was used to select the sample. Data collection was carried out using pretests and posttests to measure the improvement in cognitive learning outcomes, while posttests were used to assess misconceptions experienced by students during learning with the Synectics model with and without mind mapping assignments. Observation sheets were also used to monitor the implementation of the learning process. The results showed an improvement in cognitive abilities for the experimental class, with an average normalized gain (N-Gain) of 0.63 (high), compared to 0.50 (moderate) for the control class. Based on a significance test at the 0.05 level, the findings revealed that the Synectics learning model with mind mapping assignments significantly outperformed the Synectics model without such assignments. Additionally, descriptive analysis of the misconceptions indicated that the Synectics model with mind mapping assignments resulted in fewer misconceptions compared to the model without mind mapping assignments.
