Abstract

This study aims to identify and explain language errors in a scientific journal article entitled "Analysis of Language Errors in Expository Texts on the Digital Platform 'Ruangguru', August 2024 Edition as a Reading Resource for High School Students," published in the Semantik Journal, Issue 3, Number 4. The method applied in this study is descriptive qualitative using a literature study approach. For data collection, observation and recording techniques were used, while data analysis was carried out using the content analysis method. The findings of this study revealed 27 language errors divided into five categories, including 12 spelling errors (typos) (44.4%), 5 word choice errors (18.5%), 4 punctuation errors (14.8%), as well as ineffective sentence structure errors and errors in the bibliography (3 each) (11.1%). The causes of these errors include minimal editing process, inadequate understanding of PUEBI (Indonesian Standards for Ethics and Education), and inaccuracies from the author. This study shows that articles analyzing language errors still contain errors, so there is a need for improvements in the quality of editing by the author and the journal's editorial team.

Abstract

This paper critically examines Jacques Rancière's rejection of Althusser's concept of interpretation in epistemological rupture, and explores its implications for character education at SMA St. Thomas 1 Medan. Rancière's critique stems from his rejection of hierarchical epistemological structures in the dichotomy between science and ideology. For Rancière, this approach constrains the division of social aesthetics of class outside of power as an ideological object, rather than as an autonomous political subject. By connecting this epistemological critique to the practice of character education, this paper argues that Rancière's principle of epistemic equality provides a theoretical foundation for building more inclusive and emancipatory learning environments. At SMA St. Thomas 1 Medan, character education that is grounded in critical reflection, autonomous thinking, and the equal recognition of all students as active moral agents aligns with Rancière's post-structural vision. The author uses a qualitative hermeneutic method to analyze primary works of Rancière and Althusser and relate them to current educational practice. Results affirm that the interpretation of Marxism must be grounded within social aesthetics, and that this framework offers a progressive, emancipatory model for character formation in secondary schools.

Abstract

Abstract: This study aims to optimize the profit of Mr. Muhammad Safwan's tofu and tempeh business in Medan City using a linear programming graphical method assisted by Autograph software. The type of research used is quantitative with a case study approach. Data were obtained through direct interviews, observations, and documentation in May 2026. The results of the study indicate that the actual condition of the business produces 48 tofu trays and 1,000 tempeh pieces per day using 546 kg of soybeans from a total availability of 600 kg, and generates a net profit of Rp1,585,800 per day. Based on the formulation of the objective function to maximize gross profit Z' = 9,600x₁ + 2,345x₂ and the main constraint 2x₁ + 0.45x₂ ≤ 600, the optimal solution obtained by the graphical method is at point B (0; 1,333.33), which is producing 1,333 tempeh pieces per day without producing tofu. The maximum gross profit reached Rp3,126,665 per day, and after deducting fixed costs of Rp1,220,000, the maximum net profit was Rp1,906,665 per day. Thus, the potential profit increase was Rp321,533 per day, or approximately 20.27% compared to the actual situation. This study demonstrates that the linear programming graphical method with the assistance of Autograph software is effective in solving profit optimization problems in MSMEs involving two decision variables. Keywords: Profit Optimization, Linear Programming, Graphical Method, Autograph, Tofu and Tempeh MSMEs Abstrak: Penelitian ini bertujuan untuk mengoptimalkan keuntungan usaha tahu tempe milik Bapak Muhammad Safwan di Kota Medan dengan menggunakan metode grafik program linier berbantuan software Autograph. Jenis penelitian yang digunakan adalah kuantitatif dengan pendekatan studi kasus. Data diperoleh melalui wawancara langsung, observasi, dan dokumentasi pada bulan Mei 2026. Hasil penelitian menunjukkan bahwa kondisi aktual usaha memproduksi 48 loyang tahu dan 1.000 pcs tempe per hari dengan penggunaan kedelai 546 kg dari total ketersediaan 600 kg, serta menghasilkan keuntungan bersih sebesar Rp1.585.800 per hari. Berdasarkan perumusan fungsi tujuan memaksimalkan keuntungan kotor Z' = 9.600x₁ + 2.345x₂ dan kendala utama 2x₁ + 0,45x₂ ≤ 600, solusi optimal yang diperoleh dengan metode grafik adalah pada titik B (0; 1.333,33), yaitu memproduksi 1.333 pcs tempe per hari tanpa memproduksi tahu. Keuntungan kotor maksimum mencapai Rp3.126.665 per hari, dan setelah dikurangi biaya tetap Rp1.220.000, keuntungan bersih maksimum menjadi Rp1.906.665 per hari. Dengan demikian, potensi peningkatan keuntungan sebesar Rp321.533 per hari atau sekitar 20,27% dibandingkan kondisi aktual. Penelitian ini membuktikan bahwa metode grafik program linier dengan bantuan software Autograph efektif untuk menyelesaikan permasalahan optimalisasi keuntungan pada UMKM yang melibatkan dua variabel keputusan.
