<![CDATA[ABSTRACT This study was motivated by the low accuracy of back serve skills among sepak takraw extracurricular participants at SMAN 1 Plampang, as indicated by inaccurate service direction, balls going out of bounds, and serves that were easily anticipated by opponents. The study aimed to analyze the effect of pecing pad training and peer-toss training, the effect of leg length, and the interaction between both variables on back serve accuracy in sepak takraw. The study employed a quasi-experimental method using a 2×2 factorial design. The sample consisted of 24 sepak takraw extracurricular participants who were divided into four treatment groups based on training model and leg length category. The research instruments included a leg length measurement test and a back serve accuracy test with 20 serving attempts. Data were analyzed using normality testing, homogeneity testing, two-way ANOVA, and Tukey’s post hoc test at a significance level of 0.05. The results showed that peer-toss training produced greater improvement in back serve accuracy compared to pecing pad training. Participants with longer legs also demonstrated better serve performance than those with shorter legs. In addition, there was a significant interaction between training model and leg length on back serve accuracy. These findings indicate that dynamic training methods are more effective in improving motor adaptation and serve accuracy when adjusted to participants’ anthropometric characteristics. ABSTRAK Penelitian ini dilatarbelakangi oleh rendahnya ketepatan servis punggung peserta ekstrakurikuler sepak takraw SMAN 1 Plampang yang ditunjukkan melalui kesalahan arah servis, bola keluar lapangan, dan servis yang mudah diantisipasi lawan. Penelitian bertujuan menganalisis pengaruh latihan pecing pad dan lambungan teman, pengaruh panjang tungkai, serta interaksi kedua variabel terhadap ketepatan servis punggung sepak takraw. Penelitian menggunakan metode eksperimen semu (quasi experimental) dengan rancangan faktorial 2×2. Sampel penelitian berjumlah 24 peserta ekstrakurikuler sepak takraw yang dibagi ke dalam empat kelompok perlakuan berdasarkan model latihan dan kategori panjang tungkai. Instrumen penelitian menggunakan tes pengukuran panjang tungkai dan tes ketepatan servis punggung dengan 20 kesempatan servis. Analisis data dilakukan menggunakan uji normalitas, uji homogenitas, analisis varians dua jalur (two way ANOVA), dan uji lanjut Tukey pada taraf signifikansi 0,05. Hasil penelitian menunjukkan bahwa latihan lambungan teman memberikan peningkatan ketepatan servis yang lebih baik dibandingkan latihan pecing pad. Peserta dengan tungkai panjang juga menunjukkan hasil servis yang lebih tinggi dibandingkan peserta bertungkai pendek. Selain itu, ditemukan adanya interaksi antara model latihan dan panjang tungkai terhadap ketepatan servis punggung. Temuan ini menunjukkan bahwa latihan dengan karakter dinamis lebih efektif dalam meningkatkan adaptasi gerak dan akurasi servis apabila disesuaikan dengan karakteristik antropometri peserta.]]>
