How Does Computational Thinking Affect Mathematical Complex Problem-solving?
No full textVocational High School graduates represent the highest proportion of unemployment in Indonesia. One key factor is the mismatch between graduates’ competencies and industry demands, particularly in complex problem-solving skills. Computational thinking has great potential to enhance such abilities; however, limited studies have examined its direct effect on mathematical complex problem-solving in vocational education. This study aimed to determine the significance and magnitude of the effect of computational thinking on students’ mathematical complex problem-solving abilities and to explore how students with different levels of computational thinking approach complex mathematical problems. A mixed-methods approach with a sequential explanatory design was applied, involving 99 informatics engineering students in the quantitative phase and 15 purposively selected students in the qualitative phase. Simple linear regression revealed a positive and significant effect of computational thinking on complex problem-solving, accounting for 69.2% of the variance. Qualitative findings showed that students with higher computational thinking demonstrated systematic and logical reasoning through structured problem-solving processes, whereas those with lower levels relied on trial and error. The findings underscore the importance of explicitly integrating computational thinking into vocational curricula to enhance students’ complex problem-solving abilities and prepare them for industrial demands
Analisis Pemodelan Matematika dalam Menentukan Strategi Optimasi Laba pada UMKM Keripik Tahu Yuka
No full textSetiap pelaku usaha, termasuk Usaha Mikro Kecil dan Menengah (UMKM), tentunya ingin memperoleh keuntungan maksimal. Namun, seringkali produksi dilakukan tanpa pertimbangan proporsional terhadap permintaan pasar, yang dapat menyebabkan kelebihan produksi dan kegagalan mencapai laba optimal. Penelitian ini berfokus pada UMKM Keripik Tahu Yuka di Kota Magelang, yang memproduksi berbagai olahan kedelai seperti tahu pong, keripik tahu, pilus tahu, dan rolade tahu. Tujuan penelitian adalah untuk menentukan jumlah produksi optimal dari masing-masing produk guna memaksimalkan laba melalui penerapan model matematika berupa pemrograman linier. Data primer dikumpulkan melalui wawancara semi terstruktur dengan pengelola UMKM, yang mencakup data bahan baku, biaya produksi, harga jual, dan permintaan pasar. Model pemrograman linier yang disusun diselesaikan menggunakan perangkat lunak POM-QM for Windows. Hasil penelitian menunjukkan bahwa untuk mencapai laba maksimum sebesar Rp 2.604.114,00 dalam satu hari, UMKM Keripik Tahu Yuka disarankan untuk memproduksi 291 pak tahu pong, 150 pak keripik tahu, 250 pak rolade tahu, dan 20 pak pilus tahu
