PENGARUH PENDEKATAN BEHAVIOR TERHADAP PERILAKU PROSOSIAL SISWA SMA

Abstract

ABSTRACT

The levels of social concern, sharing tendencies, and peer cooperation among 107 eleventh-grade Social Sciences students at SMA Negeri 7 Mataram in the 2025/2026 academic year were identified as suboptimal. Addressing this issue, a group counseling intervention based on a behavioral approach was designed to examine the extent to which shifts in students' social responses could be achieved through the integration of modeling and positive reinforcement. Using purposive sampling, a sample of 10 students exhibiting low prosocial characteristics was involved in a quasi-experiment employing a one-group pretest-posttest design. Measurement utilized a 20-item Likert-scale questionnaire, reinforced by triangulation through observation, interviews, and documentation. Post-intervention evaluation revealed an increase in the mean score from 35.80 to 54.10. A paired samples t-test yielded a t-value with 9 degrees of freedom of 11.546 (p less than 0.001), indicating a very large effect size (Cohen's d = 3.65). These findings indicate a distinct contrast in behavioral performance before and after treatment. Nevertheless, the limitations of a design without a control group warrant caution against asserting absolute causal relationships. This approach remains a potential, applicable option for school guidance and counseling practices.

ABSTRAK

Kondisi kepedulian sosial, kecenderungan berbagi, serta kerja sama rekan sebaya pada 107 siswa kelas XI IPS SMA Negeri 7 Mataram T.P. 2025/2026 teridentifikasi berada pada tingkat yang belum optimal. Berangkat dari persoalan tersebut, intervensi bimbingan kelompok berlandaskan behavioral approach dirancang untuk menguji sejauh mana pergeseran respons sosial siswa dapat dicapai melalui integrasi modeling dan positive reinforcement. Melalui purposive sampling, sebanyak 10 siswa berkarakteristik prososial rendah dilibatkan dalam eksperimen kuasi berdesain one-group pretest-posttest. Pengukuran menggunakan instrumen angket skala Likert (20 item) yang diperkuat oleh triangulasi observasi, wawancara, serta dokumentasi. Evaluasi pascaintervensi memperlihatkan kenaikan rerata skor dari 35,80 menjadi 54,10. Kalkulasi paired samples t-test menghasilkan nilai t dengan derajat kebebasan 9 sebesar 11,546 (p kurang dari 0,001) dengan ukuran efek yang sangat kuat (Cohen’s d = 3,65). Temuan ini mengindikasikan adanya kontras performa sikap yang nyata antara sebelum dan sesudah perlakuan. Kendati demikian, keterbatasan desain tanpa kelompok kontrol menuntut kehati-hatian dalam mengklaim relasi kausalitas secara mutlak. Pendekatan ini tetap berpotensi menjadi opsi aplikatif dalam praktikum bimbingan dan konseling sekolah.
