Egg production was 49,127 eggs/d during the pandemic, which was previously 46,520 eggs/d. The average family consumption was 3-8 eggs/week, which was higher than the average regional consumption. The COVID-19 pandemic has no effect on production and consumption of chicken eggs. Expensive feed prices are the biggest problem faced by farmers during the COVID-19 pandemic

The focus of the study was on moods and modality in virtual communication. The purposes of the research were to analyze the moods and modalities used by the lectures for virtual teaching to evaluate the manner of the moods and modalities realized in virtual teaching and to investigate reasons underlying the use of moods and modalities in virtual teaching. The sources of data for this research were verbal and nonverbal language from the interactions of virtual teaching. The data were utterances and gestures produced by the lecturers. The research design was qualitative research. The data were collected through recorded videos, observations, interviews, and questionnaires. The techniques of analyzing the data were applying interactive data analysis: data condensation, data display, and drawing and verification conclusion. It was found that the lectures used various kinds of moods. The declarative mood was dominantly used. In terms of modality, both modalization and modulation types of modality were used. The value of the modality selected was low, medium, and high. The manner of the mood system was realized by both marked and unmarked ones. The modalities were realized through the integration of verbal and verbal modalities. The modalities were used to manage the classroom and create a pleasant and understandable teaching and learning atmosphere. The result of this study gives a new insight into the function of language in teaching through online mode.

The objective of this study was to get the empirical evidence of the effect of using small group discussion technique on students’ achievment in reading narrative text at the third year students of MTS AL-Washliyah 30 Pematang Guntung. The method used in this study was quantitative through quasi experimental research. The population was all the third year students of MTS AL-Washliyah 30 Pematang Guntung. The total sample was 60 students that were taken by using lecturing technique Instrument of this study was multiplechoise test. Before doing the treatment, the students in experimental class were given the pre-test. Then, the students were taught by using small group discussion technique. At the end of the treatments, the students were given a post-test. T-test was used to analyze the data. Value of tobserve is 4.75 and the degree of freedom (df) is 58, whereas the value t-table on the degree of significance of 5% is 1.67. The T-test revealed that the result is significant; it is determined by the value of t Obsever which is bigger than t table. Thus, Ha is accepted because there is significant effect of using small group discussion on students’reading narrative text ability. Therefore, it can be concluded that using small group discussion is effective to improve students reading narrative text ability at the third year students of MTS AL-Washliyah 30 Pematang Guntung.

The objective of the research was to determine whether there was a significant effect of the use of digital systems on the speaking skills of the students in Seventh Grade Junior High School. This research was a quantitative research with a quasy experimental design. It was conducted in seventh grade SMP Negeri 5 Tanjungbalai in the academic year 2020/2021. The total population was 93 students and researchers took 30 students for the experimental class and 30 students for the control class which meant 60 students as a total sample. In collecting data, researchers used orraly tests by speaking about the plot of the cartoon as instruments. Tests were pre-tests given before treatment and post tests given after treatment. Then, the data obtained were analyzed using t-test ar SPSS 16 with a significance level of 5% (0.05). Furthermore, the researcher found that the post –test mean score in the experimental class was higher than the control class (6.484 > 1.688). At a significant level of 5% (95% confidence level) which shows the score 18,976. The t-test result also showed that t0 (6.484) was higher than t table as a significance level of 5% (1.688). Therefore, the results of t0 > t table result that H0 (null hypothesis) was rejected and Ha (alternative hypotheiss) was accepted. The calculation of the effect size was 1.68 which was within the range of effect criteria including the strong effect. Thus, the use of the cartoon movie has a signficant effect on students’ speaking ability in the seventh grade students of SMP Negeri 5 Tanjungbalai in academic year 2020/2021.

The addition of biofuel to diesel increases the fuel's stability, density, viscosity, energy content, and cetane number Blending biodiesel and diesel improves the viscosity of the combined fuel in comparison to diesel fuel. Recently, studies on optimizing the use of biodiesel diesel fuel have begun to examine the effects on diesel engine components and the energy conversion efficiency of biodiesel fuel use. The addition of supplements from other natural fuels is an effective option to improve energy conversion efficiency, but the blending effect causes changes in fuel properties. Therefore, further analysis is needed to meet the fuel standards used in diesel engines. This study is to obtain a clearer analysis of the effect of biofuel addition on diesel engine performance and exhaust emissions. Measurements of experiment variables such as Torque, thermal efficiency, power, bsfc, and gas emission obtained from sensors installed in each part of the laboratory scale of diesel engine. The result shows blends of biofuel and diesel can be used as alternative fuels in conventional diesel engines. The variation of power generated by both of fuel mixture shows average power without any major changes. The thermal efficiency of 30% biofuel average is better across all engine speed variations whereas the carbon monoxide variation decreases towards the same amount at 3000 rpm.
