Abstract

In today's increasingly complex life situations, mental health problems can increase, especially among students in Indonesia. Mental health problems that occur in students are related to Self-efficacy regarding the potential they have in achieving something and in dealing with pressure in certain situations. Low Self-efficacy in adolescents can cause emotional and mental disorders. Based on this, this study aims to develop a mentor application to help improve students' mental health through Self-efficacy in solving algebraic form problems. This research was conducted at SMP Negeri 2 Kedungtuban, and the subjects of this study were 30 seventh-grade junior high school students. The research method used is Research and Development (R&D), and the ADDIE Model design is used. The results of data analysis show that the mentorika application is proven to be valid because it has a significant level of 0.000 < 0.005, feasible because all variables (statements) have a value of r count > r table, and effective because it meets the individual completeness test and classical completeness test, so it can be said that the mentorika application developed is effective in improving students' mental health through Self-efficacy in solving algebraic form problems. The evaluation results show that the effect of student confidence on improving mental health in solving algebraic form problems has increased significantly after using the Mentorika application. Keywords: Mental Health, Self-Efficacy, Algebraic Forms.

Abstract

Tujuan penelitian adalah untuk mengetahui apakah model PBL berbantuan google sites dapat berpengaruh terhadap kemampuan berpikir kreatif matematis siswa. Penelitian ini dilakukan di SMA Islam Sultan Agung 3. Penelitian ini menggunakan pre-experimen design dengan one grup pretest-posttest design. Pengambilan sampel dilakukan dengan teknik purposive sampling dan terpilihlah kelas X.2 sebagai sampel penelitian. Instumen penelitian adalah pretest dan posttest yang masing-masing terdiri empat soal uraian sesuai dengan indikator kemampuan berpikir kreatif matematis. Analisis data menggunakan uji-t dan uji paired t-test dengan persyaratan uji normalitas. Hasil uji normalitas diperoleh data berdistribusi normal. Hasil uji-t didapat 0,000 < 0,05 maka  ditolak. Artinya, nilai rata-rata KKTP kemampuan berpikir kreatif matematis siswa dengan model PBL berbantuan google sites lebih dari 70. Hasil uji paired sample statistic didapat nilai rata-rata pretest sebesar 25,88 dan rata-rata posttest sebesar 80,65 kemudian dilakukan uji paired sample test didapat nilai sig. (2-tailed) sebesar 0,000 artinya < 0,05 maka   ditolak.  Artinya, ada perbedaan rata-rata kemampuan berpikir kreatif matematis sebelum dan sesudah menerapkan model pembelajaran PBL berbantuan google sites. Hasil penelitian menyatakan ada pengaruh setelah penerapan model PBL berbantuan google sites terhadap kemampuan berpikir kreatif matematis siswa.
