Abstract

This classroom action research aimed to improve students’ ability to understand multiplication and the composition method through the application of the demonstration method at MI Negeri 40 Pidie. The research was conducted in two cycles, each consisting of the stages of planning, implementation, observation, and reflection. The subjects of this study were 26 fifth-grade students, including 14 boys and 12 girls. Data were collected through observation, tests, interviews, and documentation, and analyzed using both qualitative and quantitative descriptive methods. The results revealed that the demonstration method significantly improved students’ understanding of multiplication and number composition. Before the implementation, only 48% of students achieved the minimum mastery criterion (70). After the first cycle, this number increased to 72%, and in the second cycle, it reached 92%. The improvement occurred because the demonstration method enabled students to observe concrete examples, manipulate learning materials directly, and engage in hands-on learning that fostered conceptual understanding. Moreover, students became more active, motivated, and confident in solving multiplication problems. In conclusion, the use of the demonstration method proved effective in enhancing both cognitive achievement and learning engagement among students in mathematics learning at the elementary level.

Abstract

Permintaan terhadap beton ramah lingkungan mendorong pemanfaatan limbah sebagai bahan substitusi dalam campuran beton. Penelitian ini bertujuan mengevaluasi pengaruh penggunaan limbah granit sebagai substitusi agregat kasar dan abu bonggol jagung sebagai substitusi semen dengan penambahan Sikacim terhadap sifat mekanis dan fisik beton. Metode yang digunakan adalah eksperimen laboratorium dengan mutu rencana f’c 30 MPa. Variasi campuran meliputi LG 3%, 5%, dan 8% serta ABJ 4% dan SC 0,7%. Hasil menunjukkan bahwa nilai slump meningkat seiring persentase limbah, berkisar antara 10–11 cm, dan masih memenuhi standar. Kuat tekan tertinggi dicapai pada variasi LG 5% dengan nilai 44,46 MPa, meskipun lebih rendah dari beton normal (49,80 MPa), tetapi tetap di atas mutu rencana. Daya serap air meningkat pada beton variasi, namun tetap di bawah batas maksimum 6%. Dapat disimpulkan bahwa kombinasi limbah granit, abu bonggol jagung, dan Sikacim masih menghasilkan beton dengan kualitas baik. Penelitian ini merekomendasikan batas substitusi optimal limbah granit sebesar 5% untuk menjaga keseimbangan antara kekuatan, kelecakan, dan ketahanan terhadap air.

Abstract

Ectoparasite infections frequently affect gourami fish during the seed (juvenile) phase. Immersion in piper betle extract can be a natural alternative treatment to reduce ectoparasitc infections by utulizing its bioactive compounds. This study aims to identify and analyze the prevalence and intensity of ectoparasite infecting juvenile gourami. The experimental design consisted of four treatments with three replications each. Treatment P1 (control), treatment P2 (piper betle extract at 150 mg/L), treatment P3 (piper betel extract at 200 mg/L), and treatment P4 (piper betle at 250 mg/L). The findings indicated that treatment P3 was the most effective in reducing the prevalence of Trichodina sp. (40%) and Dactylogyrus sp. (53%), and also achieved a survival rate of 90%. Treatment P4 was able to reduce the prevalence of Gyrodactylus sp. by 20%, as well as the Trichodina sp. (%), Gyrodactylus sp. (%), and Dactylogyrus sp. (%). However, the growth in length, absolute weight gain, and feed conversion ratio (FCR) were not significantly affected. The types of ectoparasite were found to infect juvenile gourami: Trichodina sp. (prevalence 40% and intensity 5 ind./fish), Gyrodactylus sp. (prevalence 20% and intensity 1 ind./fish), and Dactylogyrus sp. (prevalence 53% and intensity 2 ind./fish).

Abstract

The Pelung chicken is known for its distinctive crow, which is the main criterion for judging in contests. However, the correlation between bioacoustics and morphometrics has rarely been studied. This study aims to describe the characteristics of Pelung chicken (Gallus gallus domesticus) crowing and its correlation with morphometrics. A survey method with a purposive sampling technique was used on 20 chickens in the general category and 20 chickens in the Jajangkar category at the 7th Rector Cup contest at Garut University on November 10, 2024. The observed variables were bioacoustics, including the number of syllables, vocalization duration, volume, and frequency, as well as morphometrics, including neck length, neck circumference, and body weight. The data were analyzed using the Mann-Whitney U test and the Spearman correlation test. Results showed that chickens in both categories had three syllables with a crowing duration of 10.10 seconds, a volume of 39.28 dB, and a frequency of 456.95 Hz in the general category. The Jajangkar category had a crowing duration of 9.15 seconds, a volume of 39.90 dB, and a frequency of 459.35 Hz. The Mann-Whitney U test revealed significant differences: the general category had a higher total duration and second syllable than the Jajangkar category. A significant positive correlation was found between body weight, voice volume, and voice frequency in the general category. In the Jajangkar category, neck length showed a significant positive correlation with duration and frequency. However, there was a significant negative correlation between body weight and frequency and between neck circumference and volume.

Abstract

In Indonesia, many industrial companies still pay little attention to the physical fitness of their employees. If physical fitness is not maintained properly, there could be chronic physical illness, which seems to cause middle age to depend on others in their lives, thus affecting their quality of life. Therefore, in order to maintain physical fitness with a small risk of sports injury, it is better to choose water sports because they are safer than sports on land and allow for increased amplitude of movement and energy expenditure for middle age, one of which is aquarobics. Therefore, the researcher aims to examine the effect of aquarobics on the level of physical fitness of industrial employees. This study uses a quantitative approach with an experimental method with a One Group Pretest-Posttest Design research design. The population in this study involved industrial employees in Sindang Palay, Rahayu Village, Bandung Regency, totaling 30 people, then the sample used was 7 people selected using purposive sampling techniques. The instruments used are the Harvard step test, sitting standing from a chair for 30 seconds, sit and reach, time up and go, to find out how much the level of physical fitness is. Based on data analysis through paired t test at Alpa 0.05, it can be concluded that there is a significant effect of aquarobic exercise on physical fitness. Thus because of this significance, it can be known that aquarobics can affect the physical fitness of industrial employees.
