Abstract

This research aims to know the roles of the elders as authority holders in the means of health communication for stunting prevention implemented in Trenggalek Regency, East Java. Stunting is the failure of growth and development caused by malnutrition at the first 1000 days of a child’s life. This problem can be prevented by providing nutrition needed by pregnant women and toddlers, but for preventing this the efforts of health communication are needed so that the mindset and behaviors of the society can change according to the health standards. Therefore, at Trenggalek Regency Kenek Beraksi program was implemented involving elders who may have authority to distribute knowledge and intervene behaviors which cause stunting to children. This research is qualitative research using case study method, by data gathering using in depth interview and document study. The result of this research shows that elders have significant roles in health communication for stunting prevention at Trenggalek Regency. Elders hold authorities because of the culture in society giving them privilege as respected and trusted figures. Furthermore, their knowledge and experience give them expert power and referent power making their family follow their guidance. In health communication, their health acts as a communicator delivering health messages. The effects felt from the elders’ involvement in this health communication program include the decrease of pregnant women having anemia, the increase of the toddlers’ nutritional adequacy achievement, and the increasing weights of toddlers, which altogether reduce the number of stunting at Trenggalek Regency

Abstract

Wireless technology based on the IEEE 802.11 standard and in accordance with the KEMINFO 2019 regulations requires antennas that can adapt to changing environments. Microstrip antennas are a good solution to meet the current technological advancements because they have several advantages, such as a simple design, lightweight, easy manufacturing, and low cost. When designing a microstrip antenna, bandwidth parameters must be observed. The bandwidth of a microstrip antenna is narrow. In order to work properly, some simple techniques can be used to increase antenna bandwidth. This research proposes a reconfigurable microstrip antenna polarization using a U-slot at a frequency of (2.4– 2.485) GHz for WLAN applications. The proposed antenna reconfiguration utilizes two (2) switching mechanisms that can be turned on and off individually or simultaneously. The results of the simulation showed that Ant. 1 and Ant. 2 have a linear polarization (LP), Ant. 1 has a bandwidth of 85 MHz (2.399 – 2.484) GHz, and Ant.2 has a bandwidth of 87 MHz (2.398– 2.485) GHz, both with S-parameter values ≤-9.54 dB. Then, Ant. 3 has a right circular polarization with a bandwidth value of 124 MHz (2.397 – 2.484) GHz, and Ant. 4 has a left circular polarization with a bandwidth value of 87 MHz (2.398 – 2.485) GHz at the Axial Ratio (AR) limit of ≤ 3 dB.

Abstract

Quality feed in aquaculture is very important to increase the growth and health of fish. Low feed efficiency can be overcome by feed supplementation using catalytic enzymes. One of the enzymes that can stimulate digestion is protease in red ginger plants. The protease enzyme in red ginger plants plays a role in breaking peptide bonds in place of carboxyl groups so that peptides are formed from complex compounds into simpler compounds. This study aims to determine the profile of amino acids and proximate in feed given red ginger enzymes. This research uses descriptive method. The feed sample used was commercial feed with 4 treatments namely Control (without red ginger enzyme), treatment A (1%), treatment B (3%), and treatment C (5%). The analyzes carried out included red ginger enzyme extraction, protease enzyme purification, proximate and amino acid analysis of each type of feed. The results showed that the results of the SDS-Page analysis on the red ginger protease sample contained at 67.1 kDa. The results of the proximate analysis showed the highest value in feed containing 3% red ginger protease (B) with a percentage of 42.69%. The resulting amino acid content consists of 8 non-essential amino acids namely, L-serine, L-glutamic acid, L-alanine, L-arginine, glycine, L-aspartic acid, L-tyrosine and L-proline. While the essential amino acids consist of 7 types of amino acids namely, L-Phenylalani, L-Isoleucine, L-Valine, L-Lysine, L-Leucine, L-Threonine and L-Histidine. The best type of feed is feed B, which is feed with the addition of 3% red ginger protease.

Abstract

Learning physics through the investigation of phenomena using practicum equipment in the laboratory is the real core of learning physics. The basic competence of prospective science teachers towards understanding concepts through investigating phenomena is well developed. The achievement of other, more abstract concept representation competencies such as numerical, graphical, and mathematical representations requires new methods or ways in the learning process. The development of computer technology as part of further investigation of learning in the laboratory needs to be developed to facilitate learning. The purpose of this research is to investigate how to improve competence in understanding concepts based on verbal representations (Verb Rep) in the form of investigations of phenomena, to achieve multiple representations (MR) (Formal Representation, Numerical Representation, Graphical Representation, Pictorial Representation) with computer-based learning. The results showed that the conventional group (N=30; M=72.87; SD = 7.03; SE = 1.28) had a lower average score on the test results than the experimental group (N = 30; M = 83.27; SD = 4.93; SE = 0.89). Independent mean statistical tests showed significant differences (t (30) = -6.63; p <0.001; r = 0.78) between groups learning to use one representation (conventional) and those using MR to solve problem-solving cases of lens content and curved mirrors, with the category of effect size (r)0.78 exceeding 0.50 (large effect).

Abstract

This article is the result of a literature survey on Ethno pedagogy and education in the Society 5.0 era from various sources, including digital books, journal articles, and reports on the internet. In the field of education, Society 5.0 can utilize technology to provide more interactive and personalized learning, such as online learning or the use of Augmented Reality (AR) and Virtual Reality (VR) in learning. This era demands that education must be properly prepared to help individuals develop the skills and knowledge needed to face future challenges. The purpose of this paper is to examine more deeply the ethno-pedagogy approach and how this approach can be applied in preparing education in the Society 5.0 era. The culture-based educational approach is called Ethno pedagogy. The approach is very relevant in preparing education in the increasingly complex and diverse era of Society 5.0. This approach allows teachers to develop learning content that reflects students' cultural values. Technology can be a very useful tool in supporting an ethno-pedagogy approach

Abstract

The ability to think critically is one of the profiles of Pancasila students that students must possess in the independent curriculum. Critical thinking skills are one of the abilities that students need in solving problems. This research aims to describe the implementation of interactive Science ebooks based on PBL to enhance the critical thinking skills of students in the topic of environmental pollution. The research design used is quantitative descriptive. The research design used a one-group pretest-posttest design. The population of the study is all seventh-grade students of SMPN in Yogyakarta. The sample of this research is the seventh-grade student’s one of the junior high schools in Yogyakarta, selected through simple random sampling technique. The research instrument used is a multiple-choice critical thinking test with five indicators. Indicators of critical thinking abilities are explaining, evaluation, concluding, analysis, and designing strategies. The results showed an improvement in critical thinking skills through the N-gain test of 0.8, indicating a high category. The average indicator of students' critical thinking skills who obtained the highest score was the explaining indicator with an average of 90.5%, while the indicator with the lowest average among students' critical thinking skills was the analysis indicator with an average of 70.01%. This indicates that the use of Science Ebook Innovation Based on Project-Based Learning (PjBL) can enhance the critical thinking skills of students. It is expected that this research can provide references for future researchers, and innovations related to interactive teaching materials can be developed not only for one subject but for all subjects in middle school science.

Abstract

Sound is one of the most critical components of singing. A lack of sound understanding can affect students' ability to sing due to the lack of use of learning media in class. The study aimed to determine the effectiveness and feasibility of Powtoon-based animated video learning media on singing abilities in third-grade students using the 10-step Research and Development (R&D) research method developed by Borg and Gall. Data collection techniques using observation, interviews, questionnaires, and documentation. The results of product data analysis in the form of learning media validation were carried out by experts in the field of materials and media with a percentage of 83.75% and 87.5% with the criteria of "very feasible." The effectiveness of the developed media is known based on the increase in the percentage of students' pretest and posttest scores on the knowledge aspect of 0.43% in the "moderate" category and 0.31% in the skills aspect in the "moderate" category. The results of the teacher and student response questionnaire to the media obtained a percentage of 79.57% with the "very decent" criteria. Based on this, portion-based animated videos can improve students' sound understanding and ability to sing and are suitable for use as a support for the learning process in elementary schools.

Abstract

The Independent Curriculum is a curriculum with diverse intra-curricular learning where the content will be optimized so that students have enough time to explore concepts and strengthen competencies. The purpose of this study was to identify and obtain information about the level of readiness of education units in Depok City in implementing the independent curriculum. The research method used is the descriptive qualitative method, which describes the subject the situation, and data obtained during observations and questions so that it becomes useful information and is easily understood by readers. The results of this study indicate that the level of readiness for implementing an independent curriculum in schools in high school education units in Depok City, West Java, is still not optimal. Two of the three schools have not implemented an independent curriculum, although the school has received socialization and understanding related to the independent curriculum. The key to the success of implementing an independent curriculum is good collaboration between school principals and teachers. In addition, the principal as a leader must be able to change the mindset of the Human Resources in the school to want to make changes so that the independent curriculum can be applied. Likewise, in the project of strengthening the profile of Pancasila students, it is still limited and has not led to a local culture-based learning model
