Abstract

This study aimed to describe the level of students 'emotional intelligence, the level of students' mathematical problem-solving abilities, and the relationship between emotional intelligence and mathematical problem-solving skills. This research is a quantitative study using the ex post facto correlation method. The research sample was students of class VIII SMP Negeri 3 Teras Boyolali in the 2018/2019 academic year, and the sample was determined using the purposive sampling technique. Data were collected using questionnaires, tests, and documentation. All data were analyzed using descriptive analysis, research data using the product moment formula, and hypothesis testing. The results of the study show that: (1) The emotional intelligence of students with low emotional intelligence is 28.1%, 37.5% moderate, and 34.4% high, Mathematical problem-solving abilities of students with low math problem-solving abilities with a percentage of 29.7%, moderate 35.9%, and high 34.4%, (3) After the data were analyzed using the product moment correlation technique, the correlation coefficient value was obtained from 0.586 and then compared table r with the number. A significant level of 1%, namely 0.2075. It is proven that the results count tabel r r  in this study are substantial, in the sense of the hypothesis which states, "There is a significant relationship between emotional intelligence and the ability to solve math problems in class VIII students of SMP Negeri 3 District Teras Boyolali Regency".

Abstract

Bullying merupakan permasalahan serius dalam dunia pendidikan yang telah merambah hingga tingkat sekolah dasar dan berdampak negatif tidak hanya pada korban, tetapi juga pada pelaku dan saksi. Masalah ini memerlukan intervensi yang efektif dan sesuai dengan karakteristik perkembangan siswa sekolah dasar. Penelitian ini bertujuan untuk menganalisis efektivitas penggunaan buku cerita "Mutiara Yang Terpendam" sebagai alat intervensi anti-bullying pada siswa sekolah dasar. Penelitian menggunakan pendekatan pra-eksperimental dengan desain pretest-posttest satu kelompok yang melibatkan 28 siswa kelas II. Data mengenai sikap anti-bullying dikumpulkan melalui observasi, wawancara, dokumentasi, serta pretest dan posttest. Hasil analisis menunjukkan peningkatan signifikan rata-rata skor posttest sebesar 12,5 poin (34,8%) dibandingkan dengan pretest, dengan nilai t = -13.132 (p < 0,001). Nilai effect size pada Cohen's d mencapai 1,85, mengindikasikan bahwa intervensi berbasis literasi ini sangat efektif dalam mengubah sikap siswa terhadap bullying. Intervensi menggunakan buku cerita "Mutiara Yang Terpendam" terbukti efektif sebagai strategi anti-bullying di sekolah dasar. Proses membaca sebagai interaksi dinamis antara pembaca dan teks berkontribusi pada peningkatan pemahaman dan perubahan sikap siswa. Hasil penelitian ini memberikan implikasi penting bagi pengembangan intervensi berbasis literasi sebagai alternatif strategis dalam memitigasi perilaku bullying di lingkungan sekolah dasar.

Abstract

This study aims to analyze transportation costs in distributing Mr. Rusman's coffee beans from Candiroto and Bejen plantations to five destination stores: Seleksi, Muneng, Plosogaden, Lancar, and Berkah, using the Northwest Corner Method (NWC), Least Cost Method (LC), Vogel's Approximation Method (VAM), and Modified Distribution Method (MODI). Data were obtained through direct interviews with plantation owners regarding capacity, demand, and distribution costs. The results showed that the NWC resulted in a cost of Rp610,000, the LC Rp538,500, and the VAM Rp524,500. Testing using the MODI showed that the NWC and LC methods were not optimal and required iterations for improvement, while the VAM method was immediately optimal. After optimization, the minimum cost was obtained at Rp524,500. The calculation results also used POM QM for Windows V5 software and showed similar results to manual calculations.
