Upaya Meningkatkan Kepercayaan Diri Anggota PMR Melalui Teknik Self-Disclosure di SMAN 11 Banjarmasin

Kepercayaan diri berperan penting dalam mendukung partisipasi sosial dan keterlibatan peserta didik dalam kegiatan ekstrakurikuler. Asesmen awal pada anggota Palang Merah Remaja (PMR) SMA Negeri 11 Banjarmasin menunjukkan keraguan dalam mengemukakan pendapat, berdiskusi, dan tampil di depan kelompok. Penelitian ini bertujuan meningkatkan perilaku kepercayaan diri melalui teknik self-disclosure berbantuan kartu Truth or Dare dalam layanan bimbingan kelompok. Penelitian menggunakan desain Penelitian Tindakan Bimbingan dan Konseling (PTBK) model Kemmis dan McTaggart dalam tiga siklus, masing-masing meliputi perencanaan, tindakan, observasi, dan refleksi. Delapan anggota PMR dipilih secara purposif berdasarkan asesmen kebutuhan. Data dikumpulkan melalui angket kepercayaan diri pada pra-siklus, observasi perilaku pada setiap tahap, dan dokumentasi, kemudian dianalisis secara deskriptif komparatif. Angket pra-siklus menghasilkan rata-rata 58,67%, sedangkan observasi awal menunjukkan 56,7%. Hasil observasi meningkat menjadi 60,0% pada Siklus I, 62,5% pada Siklus II, dan 70,3% pada Siklus III. Pada akhir tindakan, tujuh dari sepuluh indikator mencapai ambang ketercapaian minimal 70%, sehingga kriteria keberhasilan operasional terpenuhi. Peningkatan paling menonjol terjadi pada inisiatif mengangkat tangan, mobilitas aktif, dan ketangguhan terhadap kesalahan. Temuan ini menunjukkan bahwa teknik self-disclosure berbantuan kartu Truth or Dare berpotensi mendukung pengembangan perilaku kepercayaan diri anggota PMR melalui interaksi kelompok yang terstruktur. Strategi ini juga memberikan kesempatan berlatih berbicara secara bertahap dan sukarela. Namun, temuan terbatas pada delapan peserta didik tanpa kelompok pembanding sehingga tidak memungkinkan kesimpulan kausal atau generalisasi luas.

Efforts to Increase the Self-Confidence of PMR Members Through Self-Disclosure Techniques at SMAN 11 Banjarmasin

Abstract

Self-confidence plays an important role in supporting students’ social participation and engagement in extracurricular activities. Preliminary assessments of Youth Red Cross (PMR) members at SMA Negeri 11 Banjarmasin revealed difficulties in expressing opinions, participating in discussions, and speaking in front of groups. This study aimed to improve students’ self-confidence through self-disclosure techniques assisted by Truth or Dare cards in group guidance services. The study employed a Guidance and Counseling Action Research (PTBK) design based on Kemmis and McTaggart’s model, conducted in three cycles involving planning, action, observation, and reflection. Eight PMR members were selected through purposive sampling based on a needs assessment. Data were collected using a pre-cycle self-confidence questionnaire, behavioral observations across all stages, and documentation, then analyzed using descriptive comparative analysis. The pre-cycle questionnaire yielded an average score of 58.67%, while initial behavioral observations indicated 56.7%. Observed behavioral confidence increased to 60.0% in Cycle I, 62.5% in Cycle II, and 70.3% in Cycle III. By the final cycle, seven of ten behavioral indicators had reached the minimum achievement threshold of 70%, meeting the predefined success criteria. The greatest improvements occurred in volunteering to participate, active mobility, and resilience when making mistakes. These findings suggest that self-disclosure techniques supported by Truth or Dare cards may promote self-confidence through structured group interactions and gradual communication practice. However, the small sample size and absence of a comparison group limit causal interpretation and generalizability.
