Abstract

Tujuan penelitian ini adalah untuk Menganalisis stabilitas lereng yang ada di ruas Jalan Poros Tabang dan menganalisis keandalan struktur dinding penahan tanah apabila diaplikasikan pada penanganan longsoran yang ada di ruas Jalan Poros Tabang. Penelitian ini dilaksanakan pada ruas jalan Poros Kembang Janggut–Tabang di Kabupaten Kutai Kartanegara, sebagaimana ditunjukkan pada Gambar 3. Data yang digunakan merupakan data primer yang diperoleh melalui survei langsung di lapangan, meliputi hasil pengukuran topografi pada titik longsor 1 serta data uji tanah dari masing-masing titik longsor. Dari 15 titik yang diidentifikasi memiliki potensi longsor berdasarkan hasil investigasi, penelitian ini difokuskan pada satu titik, yaitu titik 1, yang dipilih sebagai sampel untuk analisis. Untuk memberikan gambaran umum mengenai tahapan pelaksanaan penelitian, disusun kerangka pikir dalam bentuk diagram alir yang menjelaskan alur dan skema penelitian secara sistematis. Dari hasil analisa terhadap mekanisme longsoran toe circle dengan metode irisan pada penampang kondisi eksisting, didapat nilai faktor keamanan sebesar 3,798 atau lebih besar dari 1,5 yaitu nilai faktor keamanan sesuai dengan ketentuan dalam SNI 8460:2017.  Sedangkan dari hasil analisa terhadap mekanisme longsoran toe circle dengan metode Bishop pada penampang kondisi eksisting, didapat nilai faktor keamanan sebesar 4,885 atau lebih besar dari 1,5 yaitu nilai faktor keamanan sesuai dengan ketentuan dalam SNI 8460:2017. Berdasarkan hasil ini, dapat disimpulkan bahwa kondisi lereng eksisting yang berada pada ruas jalan poros Tabang berada dalam kategori stabil, sehingga memenuhi persyaratan keandalan stabilitas lereng.

Abstract

This study aims to examine the effectiveness of the Peer-Supported Practice Strategy (PSPS) in reducing PSA among university students enrolled in a Public Speaking class, as well as to explore how students with different speaking proficiency levels respond to the strategy. Using a mixed-method approach, the research employed a quasi-experimental one-group pretest–posttest design complemented by qualitative interviews. Thirty students participated in the study and completed a 12-item PSA questionnaire administered before and after the PSPS intervention. Quantitative data were analyzed using descriptive statistics, paired sample t-tests, and independent t-tests. The results showed a notable decrease in PSA, with mean scores dropping from 45.93 (pretest) to 39.28 (posttest). The paired sample t-test revealed a statistically significant reduction, indicating that PSPS effectively lowered students’ anxiety levels. Furthermore, the independent t-test showed that both beginner and advanced proficiency groups benefited from the strategy, although beginners experienced a greater reduction. Qualitative interview findings further supported the quantitative results. Students reported feeling more comfortable, less fearful of making mistakes, and more confident when speaking with peers who offered supportive feedback. They emphasized that practicing in a non-judgmental environment, receiving constructive correction, and engaging in repeated speaking tasks helped them manage anxiety more effectively. Overall, the integration of peer support within structured speaking practice proved beneficial in reducing anxiety and increasing students’ speaking confidence. The findings suggest that PSPS can serve as an effective pedagogical approach for public speaking courses, particularly for students who struggle with communication apprehension.
