Abstract

This study aims to determine the effect of work climate on teacher performance at MTs Swasta Cerdas Murni. The work climate here includes physical, social, and psychological conditions in the teacher's work environment, which includes aspects such as managerial support, communication between colleagues, and the level of perceived security. This research method is quantitative using a questionnaire as a data collection tool and other supporting data. The population in this study were all teachers at MTs Swasta Cerdas Murni, so that the entire population in this study was a sample of 30 teachers (population study). Based on the results of the study and the hypothesis, it shows that there is a significant influence between work climate on teacher performance at MTs Swasta Cerdas Murni. Based on the results of the study and calculations, it was found that there was an influence between work climate variables on teacher performance at MTs Swasta Cerdas Murni. The results of the hypothesis test with the T test showed that t count = 2.976, df = n-2 = 30-2 = 28. The t table value = 2.048, at the 0.05 level. Because t count ≥ t table, namely = 2.976 ≥ 2.048, with a significance value of 0.006 (6%) it can be concluded that Ho is rejected and Ha is accepted. This is supported by the results of a simple regression test which states the relationship between the two variables, Y = 30.705 + 1.456X. The meaning of this regression equation is if the work climate value is 0, then the teacher's performance value is 30.705. The regression coefficient value of the teacher performance variable (b) is 1.456; this can be interpreted that for every 1% increase in work climate, teacher performance increases by 1.456. Furthermore, in the determination coefficient test, the R square value is obtained = 0.240, this means that the work climate variable affects the teacher performance variable by 24%. Thus, teacher performance at MTs Swasta Cerdas Murni is 24% influenced by the existing work climate and 76% is influenced by other factors or causes other than the variables studied. Nevertheless, it can be suggested for teachers and school principals to continuously improve their performance in order to achieve the school's goals effectively and efficiently.

Abstract

This study was chosen because it is believed to be able to provide a positive impact on the mathematics learning process, especially in improving students' mathematical concept understanding abilities and reducing mathematical anxiety which is often an obstacle in learning. This is to analyze the effect of the Learning Start With A Question (LSQ) strategy with the Quizizz Application on students' mathematical concept understanding abilities and mathematical anxiety at SMP Negeri 2 Bilah Barat. This study used a quasi-experimental design with the Single Group Interrupted Time Series Design approach. The study population was all students of grade VII with a sample of class VII-1 totaling 32 students, selected using the Cluster Random Sampling technique. The results showed that the LSQ strategy with the Quizizz Application had a significant effect on improving students' mathematical concept understanding abilities and reducing students' mathematical anxiety. Based on the hypothesis test using the Paired Sample T-Test, a significance value of 0.001 was obtained, which was smaller than 0.05, so that the alternative hypothesis (Ha) was accepted and the null hypothesis (H0) was rejected. This study concludes that the application of LSQ with the Quizizz Application is effective in improving students' mathematical concept understanding and reducing students' mathematical anxiety at SMP Negeri 2 Bilah Barat.

Abstract

The lack of waste management in the community of Kampung Benar Dusun VI Village, Kota Pari, Pantai Cermin District, Serdang Bedagai Regency is due to the limited knowledge and understanding of waste management in general. People still think that waste management is not important because people think that their waste will decompose by itself without thinking that this will have a huge impact if the waste continues to be left unmanaged. One way to support this waste management program is through a waste bank. A waste bank is a place that is used to make it easier for the public to sort waste, then the sorted waste will be deposited at a factory that makes crafts from waste or at a waste collection point. The aim of this research is to determine community knowledge regarding waste management, analyze existing waste management in the community and find out what strategies are effective for waste management. The method used by researchers is an integrated counseling method and systematic training. Data was collected by observing in the field and conducting in-depth interviews with informants. The results of the research show that after providing outreach to the community that waste management is important, the community also understands better about good waste management and knows effective waste management strategies to implement using the 3R system.

Abstract

Peserta didik sering merasa kesulitan dalam memahami konsep yang ada dalam matematika. Kebanyakan dari mereka merasa sulit untuk berkonsentrasi, serta mudah menyerah untuk memahami konsep matematika. Mengenai hal tersebut, adversity quotient sangat diperlukan dalam diri peserta didik. Adversity quotient merupakan faktor internal siswa yang berbentuk kegigihan, tanggung jawab, pengendalian, serta pandangan dalam menghadapi permasalahan. Kegiatan memorize Al-Qur’an diketahui dapat melatih seseorang untuk menjaga ketenangan hati, mudah konsentrasi, serta mengontrol emosi yang ada dalam diri. Tujuan dari penelitian ini yaitu mendeskripsikan kemampuan pemahaman konsep matematis dan adversity quotient siswa ditinjau dari kemampuan menghafal Al-Qur’an (Al-Qur’an memorize ability). Penelitian ini merupakan penelitian deskriptif kuantitatif dengan subjek penelitian yaitu siswa kelas VIII salah satu SMP Swasta di Binjai. Teknik pengumpulan data dalam penelitian ini menggunakan angket, dokumentasi dan wawancara. Analisis data dilakukan dengan statistik deskriptif, yaitu menarasikan/mendeskripsikan hasil angket dan wawancara.
