Abstract

Nata is a gel-like material (agar) that floats on a medium containing sugar and acid formed by the microorganism Acetobacter xylinum. This study aims to compare the addition of sugarcane juice (Saccharum officinarum) with palm wine (Arenga pinnata) as a sugar substitute on the quality of Nata de Coco. The population in this study were all (Saccaharum officinarum) and (Arenga pinnata) in open land. This type of pure experimental research using Completely Randomized Design (CRD) seven treatments and four replications. Measurable parameters in the form of texture, color, and taste were assessed by means of organoleptic tests. The results show that Nata de Coco using coconut water as the basic ingredient (A) is better than that using sugar cane juice and palm wine with an average total texture of 3.3, color 2.76, and taste 3.12. Then the concentration of sugarcane juice with treatment of 75% sugarcane juice + 25% coconut water (B), is better than the concentration of sugarcane juice and palm wine (C,D,E,F,G). The data obtained were then analyzed using the Analysis of Variance (ANOVA) significant level 5%. The quality of Nata de Coco which uses a mixture of sugarcane juice concentration is better than that of using sweet palm wine.

Abstract

The main problem in learning in formal education (schools) today is the low quality of student learning. One of the factors is the teacher's ability to manage, develop methods and select learning media. In this case the researcher tried to use the mind map method with comic media. This study aims to determine the effect of the mind map method with comic media on reading interest and cognitive learning outcomes of class VIII students in biology science subjects at SMPN 10 Mataram. This type of research is a quasi-experimental. The population in this study were all eighth grade students of SMPN 10 Mataram. This sample was taken using a simple random sampling technique, namely class VIII F as the experimental class and class VIII G as the control class. Data collection in this study was taken by giving pre-test and post-test to the sample class students. Data collection techniques using a reading interest questionnaire and objective tests that have been tested for validity and reliability. Based on the results of the study showed that the students' reading interest obtained an average of 60.54 for the experimental class with a percentage of 75.67%, while the control class was 51.79 with a percentage of 64.74% which indicated that students were included in the interested category, indicating that the reading interest of students who using the mind map method with comic media is higher than the reading interest of students who use conventional methods. Based on the results of the study, it was shown that the pre-test data obtained an average value of 51.03 for the experimental class and 51.55 for the control class. The post-test results showed an average of 77.93 for the experimental class and 68.96 for the control group. The post-test data of the sample class students were analyzed using t-test. Based on the results of data analysis using t-test obtained t count > t table, which is 4.33 > 2.00 at an error level of 5%. This indicates that the mind map method with comic media has an effect on cognitive learning outcomes for class VIII students in biology science subjects. at SMPN 10 Mataram.

Abstract

Peanut (Arachis hypogaea L.) is a legume crop and is one of the second highest yielding secondary crops after soybeans. Peanut production in Indonesia tends to fluctuate and is still not able to meet the needs of the community every year. To produce quality seeds, one of the ways that plant breeders do is by crossing. The cross in this study was a peanut cross between the national variety and the local Bima variety. The purpose of this study was to determine the vigor and viability of peanut sprouts from crosses between national and local varieties of Bima. This research is included in pure experimental research. The design used in this study was a completely randomized design. The data in the research that has been collected through observation and documentation methods are then analyzed using ANOVA One Way. Based on the results of the study, the data on viability parameters were obtained, namely: the highest percentage of germination was obtained by F1A seeds (Rhinoceros Variety x Local Bima) with a value of 86.66% while the lowest percentage of germination was F1C seeds (V. Kancil x Local Bima) with a value of 20%. For the parameter of germination speed, the F1 seed which had the highest seed germination speed was F1E (V. Pelanduk x Local Bima) with a value of 2.33/day while the lowest germination rate was F1C (V. Kancil x Local Bima) with a value of 0.58/day. From all research data, it was found that data from all parameters experienced significant variations or differences with P Value < 0.05 in each treatment.

Abstract

Differences in the characteristics of students cause teachers to find it difficult to choose learning methods so that teachers often use conventional learning methods. This results in a lack of interaction between students, and has an impact on the low social skills and cognitive learning outcomes of students. The purpose of this study was to describe the effect of the talking stick learning model combined with the snowball drilling learning method on the social skills of class X SMA Negeri 1 Kerambitan students and to determine the effect of the talking stick learning model combined with the snowball drilling learning method on the cognitive learning outcomes of class X SMA Negeri 1 students. kinship. This type of research is a quasi-experimental research, the design in this study using a pretest-posttest control group design, with a sampling technique using purposive sampling. The sample of this research is class X A as the experimental class and class X B as the control class. The instruments used in this study were the RPP implementation observation sheet, social skills observation sheet, and cognitive learning outcomes test. The data analysis technique used is descriptive quantitative and t-test. After analyzing the students' social skills data, the average percentage was 16.97 with a good category, while the post-test scores for the control class were 57.1 and the experimental class was 67.4. After testing the hypothesis, the price is obtained (tcount > ttable) or (3.102 > 1.671), so that the hypothesis is accepted, so it can be concluded that there is an effect of the talking stick learning model combined with the snowball drilling learning method on the cognitive learning outcomes of grade X students of SMA Negeri 1 Kerambitan in the academic year 2017/2018, and students' social skills are classified as good.

Abstract

This research was conducted at SMA Wiyata Dharma in the 2018/2019 academic year. This study aims to increase students' motivation and cognitive learning outcomes in biology subjects by using the concept mapping learning method. The type of research used in this research is quasi-experimental or quasi-experimental. The population of this study were students of class XI SMA Wiyata Dharma 2018/2019 academic year. The samples used were 39 students of class XI IPA 5 as the control class and 39 people of class XI IPA 6 as the experimental class taken with cluster random sampling technique. Data collection techniques using observation sheets and test sheets of cognitive learning outcomes. The observation sheet was given after the learning took place in the experimental class. The observation sheet aims to determine the increase in students' learning motivation. The cognitive learning outcomes test sheets are given before and after the learning process takes place, aiming to determine the increase in students' cognitive learning outcomes. Data on students' cognitive learning outcomes in this study were taken by giving pre-test and post-test to the sample class students. The test sheet used has been tested by the validator so that it can be used in this study. The results showed that the average percentage of student learning motivation in the experimental class after using the concept mapping method was 79.67 with a high motivation category. While the value of the students' cognitive learning outcomes showed that the experimental class obtained an average score of 97.43 while the control class was 98.58. The final test data of the sample class students were analyzed using t-test. based on the results of data analysis, it was obtained that tcount was 2.57 and ttable 1.46 so that tcount was greater than ttable at an error rate of 5% and dk was 76. Therefore, from the t-test analysis it can be concluded that there is a significant effect on the results. Cognitive learning of class XI SMA Wiyata Dharma students.
