Abstract

Bahasa Inggris menjadi salah satu materi yang sulit diterima oleh siswa/i. Pendampingan ini berfokus pada peningkatan speaking skill siswi SMP Nurul Jadid yang berada di wilayah Al Hasyimiyah. Pembelajaran konvensional masih digunakan oleh para tutor di wilayah Al-Hasyimiyah. Untuk itu, metode yang digunakan adalah TROPIG (Total Physical Response, Role Play, Peer Tutoring dan Jigsaw). Keempat metode ini telah membantu dalam meningkatkan kemampuan berbicara siswa. Total Physical Response membantu siswa untuk melatih kemampuan psikomotorik siswa. Role Play dan Peer Tutoring merupakan metode yang melatih kemampuan kognitif siswa, sedangkan metode Jigsaw melatih kemampuan interpersonal dan intrapersonal siswa. Secara umum, siswa merasa terbantu dalam pembelajaran dengan menggunakan empat metode ini. Terbukti, siswa lebih percaya diri dalam berbicara didepan umum dan juga efektivitas pembelajaran terjadi

Abstract

Fenomena perubahan iklim dan kerusakan lingkungan mendorong adanya peningkatan eco parenting  untuk menumbuhkan generasi yang pro lingkungan. Tujuan dari penelitian ini adalah untuk mengetahui faktor-faktor yang memengaruhi eco parenting berdasarkan perspektif Teori Perilaku Terencana. Metode yang digunakan adalah kuantitatif survey dengan populasi orang tua di Jawa Timur yang memiliki anak dengan usia di bawah 17 tahun dan didapatkan 400 responden dengan teknik random sampling. Instrumen yang digunakan dalam penelitian ini terdiri dari instrumen eco parenting, sikap, norma subjektif, persepsi kontrol perilaku, serta literasi terkait eco parenting. Analisis data dilakukan dengan uji regresi berganda dan uji sobel. Hasil penelitian menunjukkan bahwa secara parsial hanya norma subjektif dan persepsi kontrol perilaku yang berpengaruh positif terhadap eco parenting. Secara simultan keempat variabel bebas berpengaruh sebanyak 86.2% terhadap eco parenting. Variabel norma subjektif dan persepsi kontrol perilaku dapat menjadi mediator untuk pengaruh dari variabel literasi terhadap eco parenting. Dapat disimpulkan bahwa norma subjektif dan persepsi kontrol perilaku memiliki peranan yang signifikan dalam penerapan eco parenting pada orang tua di Jawa Timur.

Abstract

This paper implements the extended MacWilliams theorem for linear codes, revisiting the MacWilliams theorem for the Complete Weight Enumerator (CWE) of codes with q = 3, 4, 5, and 7. Linear codes are a mathematical concept that can be described through the distribution of weights in each codeword. CWE serves to provide a complete representation of the symbols in each codeword. This article discusses how the MacWilliams theorem can be efficiently used to calculate the CWE of codes and optimize the design of error-correcting codes. The results of this research include the calculation of CWE for and . This study contributes theoretically to the understanding of linear code structures while opening up opportunities for the development of more efficient error-correcting code algorithms in modern communication systems.

Abstract

This paper presents the explicit forms of complete weight enumerators (CWEs) for ternary self-dual codes of lengths 4, 8, 12, 16, and 20. Complete weight enumerators polynomials describe the distribution of the symbols 0, 1, and 2 in each codeword, making them essential for analyzing non-binary codes. The results focus on the complete weight enumerators polynomials that form a basis for each code. This documentation serves as a concrete reference for further research in ternary code theory.

Abstract

This study proposes a steganography method based on the bicover concept by utilizing Max-Plus algebra through matrix multiplication operations without inverse. The proposed method uses two cover images to embed one secret image, namely the first cover image to store the MSB (Most Significant Bit) bit and the second cover image to store the LSB (Least Significant Bit) bit. The test results show that this method is able to reconstruct the secret image completely with good stego image quality. The PSNR value obtained is 31.18 dB in Stego 1 and 31.77 dB in Stego 2, while the MSE value is 49.5457 in Stego 1 and 43.2352 in Stego 2. These results indicate that the visual changes in the container image are relatively small so that the existence of the secret image is difficult to recognize. Thus, the proposed method can be an alternative in improving the security of digital data exchange.

Abstract

Penelitian ini membahas segmentasi sekolah berdasarkan pola perubahan jumlah pendaftaran mahasiswa baru Universitas Nurul Jadid selama periode 2023–2025 menggunakan metode regresi linier dan algoritma K-Means Clustering. Data yang digunakan berupa data jumlah mahasiswa baru berdasarkan asal sekolah yang diperoleh dari bagian Penerimaan Mahasiswa Baru (PMB) Universitas Nurul Jadid. Tahapan penelitian meliputi pengolahan data pendaftaran, perhitungan regresi linier untuk memperoleh nilai gradien perubahan jumlah pendaftar, evaluasi jumlah cluster menggunakan metode Silhouette Score, serta proses pengelompokan sekolah menggunakan algoritma K-Means Clustering. Hasil penelitian menunjukkan bahwa sebanyak 141 sekolah berhasil dikelompokkan berdasarkan pola perubahan jumlah pendaftar. Berdasarkan pengujian menggunakan Silhouette Score, jumlah cluster sebanyak 3 dipilih karena menghasilkan kualitas pengelompokan yang baik dengan nilai Silhouette Score sebesar 0,6039 serta memiliki interpretasi yang sesuai dengan tujuan penelitian. Hasil proses clustering menghasilkan tiga kelompok sekolah berdasarkan kecenderungan perubahan jumlah pendaftar, yaitu kelompok dengan tren peningkatan, kelompok dengan tren relatif stabil, dan kelompok dengan tren penurunan. Nilai centroid yang diperoleh pada masing-masing cluster berturut-turut adalah -0,320388, 1,896552, dan -4,055556. Metode K-Means Clustering efektif mengelompokkan sekolah berdasarkan tren pendaftar untuk evaluasi dan strategi penerimaan mahasiswa baru.

Abstract

This study aims to analyze the numerical characteristics of the number of verses in all suras of the Quran based on the concept of prime numbers using a number theory approach. This study is a library research study using a descriptive analytical approach. The research data consists of the number of verses in 114 suras of the Quran sourced from the Indonesian Standard Quranic Manuscript published by the Ministry of Religious Affairs of the Republic of Indonesia, Improved Edition, 2017. Prime numbers were identified using the remainder (modulo) method, then analyzed through frequency of occurrence, descriptive statistics, and distribution patterns. Furthermore, a structural analysis of the ruku' (bowing) was conducted by comparing the Indonesian Standard Quranic Manuscript and the Holy Quranic Manuscript.The results show that 32 suras have verses that are prime numbers, while 82 suras have verses that are composite numbers. The prime numbers that appear as the number of verses in a surah are 3, 5, 7, 11, 13, 17, 19, 29, 31, 37, 43, 53, 59, 73, 83, 89, 109, and 227, with the prime number 11 having the highest frequency of occurrence. The results of the descriptive statistical analysis show an average value (mean) of 33.625, a median of 18, a mode of 11, a minimum value of 3, and a maximum value of 227. The analysis of the ruku' structure reveals that out of 114 surahs, 107 surahs have the same number of ruku' in both mushafs, while 7 surahs show differences in the number of ruku'. These differences do not reflect differences in content, number of verses, or the arrangement of the verses of the Qur'an, but rather represent variations in the system of dividing reading themes between mushafs. This research is expected to contribute to the development of interdisciplinary studies between mathematics and Qur'anic studies, as well as become a basis for further research that examines the numerical aspects of the Qur'an using other mathematical concepts.
