ANALISIS PERBANDINGAN METODE REGRESI LINIER DAN NON-LINIER PADA SAMBUNGAN MATERIAL PELAT BAJA KARBON ASTM A36
Get PDFThe joining of ASTM A36 carbon steel plates using the Shield Metal Arc Welding (SMAW) technique is influenced by the tensile strength and hardness of the joint. To improve the quality of ASTM A36 carbon steel plate joints in the future, prediction methods are used. The prediction results play a significant role in determining the quality of the material connection.The method used in this research was descriptive quantitative, by predicting linear regression and non-linear (quadratic) regression models. The purpose of the discussion in this article was to determine the best prediction model for current variations on the tensile strength of future material connections. The analysis of the correlation coefficient showed a strong relationship in both models discussed. This indicates that the current strength variable had a strong relationship with tensile strength. Meanwhile, the highest R-square score was obtained in the non-linear regression model. The determination of the best prediction method was found in the non-linear regression model on tensile strength, with a MAPE value of 3.57%. These results indicate that the non-linear regression model better describes the relationship between current strength and tensile strength in ASTM A 36 carbon steel plate joining.The joining of ASTM A36 carbon steel plates using the Shield Metal Arc Welding (SMAW) technique is influenced by the tensile strength and hardness of the joint.

STRATEGI PENGELOLAAN DANA BEASISWA KIP KULIAH GUNA MENGATASI PERILAKU KONSUMTIF DAN MENINGKATKAN PRESTASI AKADEMIK DI FAKULTAS EKONOMI UNIVESITAS NAHDLATUL ULAMA SIDOARJO
Get PDFThis study aims to analyze the strategy of managing KIP Lecture scholarship funds to overcome consumptive behavior and improve the academic achievement of students of the Faculty of Economics, Nahdlatul Ulama University of Sidoarjo. The research method used is qualitative with a descriptive approach. Data were obtained through interviews with scholarship recipient students and the Head of Student Welfare. The results showed that although the scholarship aims to support education, some students tend to allocate funds for consumptive needs. The university implemented various strategies such as financial reporting mechanisms, financial literacy education, and the provision of student cooperatives as a means of saving. However, challenges such as late reporting and lack of financial awareness are still faced. Therefore, stricter supervision and increased student awareness in financial management are needed. With the right strategy, it is hoped that students can be more optimal in utilizing the scholarship to improve their academic performanc

THE EFFECTIVENESS OF QUIZLET IN TEACHING VOCABULARY TO EFL STUDENTS TO ELEVENTH-GRADE STUDENTS AT SMA NEGERI 1 CIKANDE SERANG
Get PDFThis study examined the effectiveness of the Quizlet application in teaching vocabulary to eleventh-grade students at SMA Negeri 1 Cikande, Indonesia. The study addressed the persistent challenge of limited vocabulary mastery in English classrooms, where traditional teaching methods often dominate and technology integration remains minimal. Using a quantitative approach with a quasi-experimental design, two classes participated: the experimental group (n = 42) received vocabulary instruction through Quizlet, while the control group (n = 42) was taught using conventional methods. Both groups completed pre-tests and post-tests to measure vocabulary knowledge, including meaning, form, and usage. Statistical analyses, such as normality, homogeneity, and independent sample t-tests, were conducted using SPSS version 30. Results showed that the experimental group’s mean score increased from 54.64 to 83.57, while the control group improved from 66.43 to 75.60. Despite starting from a lower baseline, the experimental group achieved greater gains, indicating a significant difference (p < 0.05) between the two groups. These findings confirm the positive impact of Quizlet on students’ vocabulary learning. The study concludes that Quizlet proved to be an effective and engaging tool for improving students’ vocabulary mastery and recommends integrating Quizlet into English vocabulary instruction to enhance motivation and learning outcomes.Penelitian ini menyelidiki efektivitas aplikasi Quizlet dalam mengajar kosakata kepada siswa kelas sebelas di SMA Negeri 1 Cikande, Indonesia. Penelitian ini dimotivasi oleh tantangan yang terus-menerus berupa terbatasnya penguasaan kosakata di kelas bahasa Inggris, di mana metode pengajaran tradisional sering mendominasi dan integrasi teknologi masih minim. Mengadopsi pendekatan kuantitatif dengan desain kuasi-eksperimental, penelitian ini melibatkan dua kelas: kelompok eksperimen (n = 42) menerima instruksi kosakata menggunakan Quizlet, sedangkan kelompok kontrol (n = 42) diajar menggunakan metode konvensional. Kedua kelompok menyelesaikan tes awal dan tes akhir untuk mengukur penguasaan kosakata. Analisis statistik, termasuk normalitas, homogenitas, dan uji-t sampel independen, dilakukan menggunakan SPSS versi 30. Hasil penelitian menunjukkan bahwa kelompok eksperimen mencapai peningkatan substansial dalam skor rata-rata dari 54,64 menjadi 83,57, dibandingkan dengan peningkatan yang lebih kecil dari 66,43 menjadi 75,60 pada kelompok kontrol. Uji-t menunjukkan perbedaan yang signifikan secara statistik (p < 0,05) antara kedua kelompok, yang menegaskan dampak positif Quizlet terhadap pembelajaran kosakata. Temuan ini sejalan dengan penelitian sebelumnya yang mendukung penggunaan perangkat digital interaktif dalam pembelajaran bahasa. Penelitian ini menyimpulkan bahwa Quizlet merupakan platform yang efektif, menarik, dan mudah diakses untuk meningkatkan penguasaan kosakata, dan merekomendasikan integrasinya ke dalam praktik mengajar untuk meningkatkan motivasi dan hasil belajar sisw
