Abstract

Gen 16S rRNA dapat digunakan untuk identifikasi spesies bakteri secara molekuler. Pada penelitian telah dilakukan identifikasi molekuler gen 16S rRNA isolat bakteri pendegradasi inulin dari rizosfer umbi Dahlia yang diberi kode RZ-01. Penelitian ini bertujuan untuk menentukan spesies isolat bakteri RZ-01. Isolasi DNA kromosom bakteri dilakukan sesuai metode yang dimuat pada Wizard Genomic Purification Kit by Promega. DNA kromosom isolat bakteri RZ-01 diidentifikasi dengan elektroforesis DNA. Gen 16S rRNA diamplifikasi dengan metoda Polymerase Chain Reaction (PCR) menggunakan primer BactF1 dan UniB1. Amplikon produk PCR adalah gen 16S rRNA isolat bakteri RZ-01, kemudian ditentukan urutan basa nukleotidanya berdasarkan metoda dideoxcy-Sanger menggunakan primer UniB1. Urutan basa nukleotida gen 16S rRNAisolat bakteri RZ-01dibaca menggunakan progam DNASTAR dan dianalisis menggunakan program BLASTn, Clustal Omega dan Mega 6. Ukuran fragmen gen 16S rRNAisolat bakteri RZ-01 yang diperoleh 724 bp.Konsentrasi DNA kromosom isolat bakteri RZ-01 diperkirakan 50 ng/µL. Hasil identifikasi menunjukkan isolat bakteri RZ-01 termasuk kedalam kelompok spesies Enterobacteraerogenes.

Abstract

This study aimed to produce the development of proper volleyball games learning for students. The research method used in this study was Research and Development. The development steps were done by using Analysis, Design, Development, Implementation and Evaluation which were often referred to the ADDIE model. The subjects in this study were the students of Physical and Health Education Study Program of Teacher Training and Education Faculty of Sriwijaya University. The results of this study indicated that overall the development of volleyball games learning is feasible to be used. The data analysis technique used was quantitative descriptive analysis. The results of this study included the development of facilities, infrastructure, and rules of volleyball games. In the facilities aspect was by changing the height of the net to 2.15 meters. In the infrastructure aspect modified the size of the field to be 16x9 meters. While in the rules of the game aspect combined female and male students. The feasibility of the development was obtained from the results of the assessment of material experts which were obtained an average of 80.67% included in the good category while the effectiveness was obtained from the learning outcomes of the implementation phase of students with the outcome on the psychomotor aspect was 77.08% included in the sufficient category. The implementation of this development research was that the educators could use as an alternative in teaching and could improve the students’ learning outcomes on psychomotor aspect.

Abstract

The purpose of this research is to produce learning techniques for volleyball service for class IX Junior High School so that by producing new learning techniques, the learning outcomes of student service will be better, this research and development is intended to be a solution to the problem of volleyball game service at junior high school students. This research uses the Research and Development (R&D) method using the ADDIE development procedure (Analyze, Design, Development, Implementation, and Evaluation). Data was collected through documentation, observation, questionnaires and top service assessment tests. Data analysis was carried out descriptively, qualitatively and quantitatively. The product implementation stage was carried out in class IX.2 totaling 32 students and IX 4 totaling 32 students at Junior High School No 1 Palembang using the development results in the form of 8 top service drill learning techniques that had been declared valid. The learning outcomes of student service in the realm of attitudes, knowledge and skills obtained an average of 88.58% of students passed the minimum completeness criteria. Based on these learning outcomes, it can be concluded that 8 top service drill learning techniques are said to be effective in learning to serve volleyball games in junior high school students. The findings in this study are that the 8 drill learning techniques developed for top service can be used as a reference for learning techniques that can improve learning outcomes for volleyball service learning.

Abstract

The aim of this study was to determine the anthropometric profile data and physical fitness of elementary school children aged 10-12 years 11 Tanjung Batu public elementary school 2020-2021. The method used in this research is quantitative descriptive method by measuring and testing TKJI 2010, the total sample is 25 students. The results of the research obtained on the anthropometric profile to see the body mass index obtained the nutritional status of 18 underweight students, 7 normal people, on the physical fitness test, 5 people were in good category, 16 people were enough, and 4 people were enough, and there was a relationship between anthropometric profiles. with students' physical fitness. After the data has been obtained, the teachers at the 11 Tanjung Batu public elementrary school can review and make a reference in the upcoming learning process, so that anthropometric data and the level of student’s physical fitness can improve from before and will be even better.
