Abstract

Kemampuan problem solving merupakan keterampilan penting yang dibutuhkan peserta didik dalam menghadapi tuntutan pembelajaran dan dunia kerja pada abad ke-21. Namun berdasarkan hasil pra-riset yang dilakukan di SMKN 31 Jakarta, kemampuan problem solving peserta didik masih perlu ditingkatkan, dengan self-efficacy (77,8%) dan komunikasi interpersonal (72,2%) teridentifikasi sebagai faktor yang paling dominan memengaruhinya. Penelitian ini bertujuan untuk menganalisis pengaruh self-efficacy dan komunikasi interpersonal terhadap problem solving peserta didik kelas XI SMKN 31 Jakarta, baik secara parsial maupun simultan. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei. Populasi penelitian sebanyak 208 peserta didik kelas XI SMKN 31 Jakarta dari enam program keahlian, dengan sampel sebanyak 137 responden yang ditentukan menggunakan teknik proportional random sampling. Pengumpulan data dilakukan melalui kuesioner skala Likert yang disebarkan secara daring. Analisis data menggunakan Structural Equation Modeling berbasis Partial Least Square (SmartPLS 4.0). Hasil penelitian menunjukkan bahwa self-efficacy berpengaruh positif dan signifikan terhadap problem solving dengan koefisien jalur sebesar 0,455, t-statistic sebesar 7,843, dan p-value sebesar 0,000. Komunikasi interpersonal juga berpengaruh positif dan signifikan terhadap problem solving dengan koefisien jalur sebesar 0,452, t-statistic sebesar 7,606, dan p-value sebesar 0,000. Secara simultan, self-efficacy dan komunikasi interpersonal mampu menjelaskan 40,7% variasi kemampuan problem solving peserta didik, ditunjukkan oleh nilai R-square sebesar 0,407 yang termasuk dalam kategori moderat. Temuan ini menunjukkan bahwa semakin tinggi self-efficacy dan semakin baik komunikasi interpersonal peserta didik, maka kemampuan problem solving mereka juga akan semakin meningkat. ***** Problem solving is an essential skill that students need to meet the demands of learning and the world of work in the 21st century. However, based on a preliminary study conducted at SMKN 31 Jakarta, students' problem solving skills still need improvement, with self-efficacy (77.8%) and interpersonal communication (72.2%) identified as the most dominant factors influencing it. This study aims to analyze the influence of self-efficacy and interpersonal communication on problem solving skills of grade XI students at SMKN 31 Jakarta, both partially and simultaneously. This study employed a quantitative approach with a survey method. The population consisted of 208 grade XI students from six study programs at SMKN 31 Jakarta, with a sample of 137 respondents selected using proportional random sampling. Data were collected through an online Likert scale questionnaire. Data analysis was conducted using Structural Equation Modeling based on Partial Least Square (SmartPLS 4.0). The results show that self-efficacy has a positive and significant influence on problem solving, with a path coefficient of 0.455, t-statistic of 7.843, and p-value of 0.000. Interpersonal communication also has a positive and significant influence on problem solving, with a path coefficient of 0.452, t-statistic of 7.606, and p-value of 0.000. Simultaneously, self-efficacy and interpersonal communication account for 40.7% of the variation in students' problem solving skills, as indicated by an R-square value of 0.407, which falls into the moderate category. These findings indicate that the higher students' self-efficacy and the better their interpersonal communication, the better their problem solving skills will be.
