Abstract
Penelitian ini bertujuan untuk menganalisis pengaruh stres akademik dan manajemen waktu terhadap prokrastinasi akademik dengan cyberloafing sebagai variabel intervening pada siswa SMKN 8 Jakarta. Metode yang digunakan adalah pendekatan kuantitatif. Sampel terdiri dari 257 siswa yang dipilih dari populasi kelas X dan XI berjumlah 715 siswa menggunakan rumus Slovin dan teknik proportional random sampling. Data dianalisis menggunakan Structural Equation Modeling (SEM) berbasis Partial Least Squares (PLS) dengan perangkat lunak SmartPLS 4.0. Hasil uji outer model menunjukkan bahwa instrumen telah memenuhi kriteria convergent validity, discriminant validity (HTMT < 0,90), serta reliabilitas dengan nilai composite reliability dan cronbach's alpha > 0,70. Evaluasi inner model menghasilkan nilai R-Square sebesar 0,082 untuk cyberloafing dan 0,445 untuk prokrastinasi akademik. Pengujian hipotesis pengaruh langsung membuktikan bahwa stres akademik (β = 0,402; t-value = 8,259; p-value = 0,000) dan cyberloafing (β = 0,331; t-value = 4,702; p-value = 0,000) berpengaruh positif terhadap prokrastinasi akademik. Sebaliknya, manajemen waktu berpengaruh negatif terhadap prokrastinasi akademik (β = -0,294; t-value = 5,651; p-value = 0,000). Selain itu, stres akademik memengaruhi cyberloafing secara positif (β = 0,238; t-value = 3,802; p-value = 0,000), sedangkan manajemen waktu memengaruhinya secara negatif (β = -0,166; t-value = 2,742; p-value = 0,006). Pada pengujian efek mediasi, cyberloafing terbukti memediasi pengaruh stres akademik terhadap prokrastinasi akademik secara positif (β = 0,079; t-value = 3,558; p-value = 0,000) dan memediasi pengaruh manajemen waktu terhadap prokrastinasi akademik secara negatif (β = -0,055; t-value = 2,104; p-value = 0,035). Sehingga dapat dipahami bahwa cyberloafing bisa menjadi titik terjadinya prokrastinasi akademik; dimana stres akademik berpengaruh positif dan manajemen waktu berpengaruh negatif terhadap kedua variabel tersebut, dengan cyberloafing yang terbukti memediasi hubungan keduanya terhadap prokrastinasi akademik.***** This study aims to analyze the effect of academic stress and time management on academic procrastination with cyberloafing as an intervening variable among students of SMKN 8 Jakarta. The method used is a quantitative approach. The sample consists of 257 students selected from a population of 10th and 11th grade with total of 715 students using the Slovin formula and proportional random sampling technique. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) via SmartPLS 4.0 software. The outer model test results indicate that the instrument has met the criteria for convergent validity, discriminant validity (HTMT < 0.90), and reliability with composite reliability and cronbach's alpha values > 0.70. The inner model evaluation yielded an R-Square value of 0.082 for cyberloafing and 0.445 for academic procrastination. Direct effect hypothesis testing proves that academic stress (β = 0.402; t-value = 8.259; p-value = 0.000) and cyberloafing (β = 0.331; t-value = 4.702; p-value = 0.000) have a positive effect on academic procrastination. Conversely, time management has a negative effect on academic procrastination (β = -0.294; t-value = 5.651; p-value = 0.000). Furthermore, academic stress positively affects cyberloafing (β = 0.238; t-value = 3.802; p-value = 0.000), while time management affects it negatively (β = -0.166; t-value = 2.742; p-value = 0.006). In the mediation effect testing, cyberloafing is proven to mediate the effect of academic stress on academic procrastination positively (β = 0.079; t-value = 3.558; p-value = 0.000) and mediate the effect of time management on academic procrastination negatively (β = -0.055; t-value = 2.104; p-value = 0.035). Ultimately, cyberloafing serves as the starting point that triggers academic procrastination; whereas academic stress positively affects and time management negatively affects both variables, with cyberloafing proven to effectively mediate these relationships toward academic procrastination.
