Pengaruh School well-being Terhadap Grit Dengan Growth Mindset Sebagai Mediator Pada Siswa SMK Harapan Bangsa Tanjung Morawa

Abstract

Siswa Sekolah Menengah Kejuruan (SMK) dituntut untuk memiliki grit dalam menghadapi berbagai tantangan, seperti persiapan kerja dan praktik industri. Namun, fenomena di lapangan menunjukkan bahwa sebagian siswa mengalami penurunan semangat, ketidakpastian karier, serta kecenderungan mudah menyerah saat menghadapi tekanan akademik. Penelitian ini bertujuan untuk menguji pengaruh school well-being terhadap grit dengan growth mindset sebagai mediator pada siswa SMK Harapan Bangsa. Penelitian ini menggunakan pendekatan kuantitatif dengan metode Structural Equation Modeling (SEM) berbasis Partial Least Square (PLS). Populasi penelitian adalah seluruh siswa SMK Harapan Bangsa sebanyak 493 orang, dengan sampel terpilih sebanyak 151 siswa kelas XII yang dipilih melalui teknik purposive sampling. Instrumen penelitian menggunakan skala school well-being, growth mindset, dan grit. Hasil penelitian menunjukkan bahwa school well-being berpengaruh positif dan signifikan terhadap grit (β = 0,392; t = 3,363; p = 0,001), dan growth mindset (β = 0,826; t = 19,770; p = 0,000). Growth mindset juga berpengaruh positif signifikan terhadap grit (β = 0,496; t = 4,202; p = 0,000). Selain itu, growth mindset secara signifikan memediasi hubungan school well-being terhadap grit (t = 4,125; p = 0,000) dengan sumbangan pengaruh tidak langsung sebesar 41,0%. Kesimpulan penelitian ini menunjukkan pentingnya peran school well-being dalam membentuk grit siswa secara langsung maupun melalui pengembangan growth mindset. Students of Sekolah Menengah Kejuruan (vocational high schools) are required to possess grit in facing various challenges, such as career preparation and industrial internships. However, in reality, some students experience decreased enthusiasm, career uncertainty, and a tendency to give up easily when dealing with academic pressures. This study aims to examine the effect of school well-being on grit with growth mindset as a mediating variable among students of Sekolah Menengah Kejuruan Harapan Bangsa. This research employed a quantitative approach using Structural Equation Modeling (SEM) with Partial Least Square (PLS). The population consisted of 493 students of Sekolah Menengah Kejuruan Harapan Bangsa, with a sample of 151 twelfth-grade students selected through purposive sampling. Research instruments included the school well-being scale, growth mindset scale, and grit scale. The results showed that school well-being had a positive and significant effect on grit (β = 0.392; t = 3.363; p = 0.001) and on growth mindset (β = 0.826; t = 19.770; p = 0.000). Furthermore, growth mindset had a positive and significant effect on grit (β = 0.496; t = 4.202; p = 0.000). Growth mindset also significantly mediated the relationship between school well-being and grit (t = 4.125; p = 0.000), with an indirect contribution of 41.0%. This study concludes that school well-being plays an important role in fostering grit both directly and indirectly through the development of a growth mindset.
