Kemampuan pemecahan masalah merupakan salah satu aspek penting dalamrnperkembangan kognitif anak usia dini yang perlu dikembangkan melalui kegiatanrnpembelajaran yang melibatkan pengalaman langsung. Penelitian ini bertujuanrnuntuk mengetahui pengaruh kegiatan eksperimen fenomena alam terhadaprnkemampuan pemecahan masalah anak usia 5–6 tahun di TK Dharma WanitarnPersatuan 2 Kesek. Penelitian ini menggunakan pendekatan kuantitatif denganrnmetode quasi experimental dan desain Nonequivalent Control Group Design.rnSampel penelitian berjumlah 25 anak, yang terdiri atas 13 anak kelompokrneksperimen dan 12 anak kelompok kontrol. Teknik pengumpulan datarnmenggunakan observasi, sedangkan analisis data menggunakan uji Mann-WhitneyrnU Test. Hasil penelitian menunjukkan bahwa diperoleh nilai Asymp. Sig. (2-tailed)rnsebesar 0,000 < 0,05, sehingga H₀ ditolak dan Hₐ diterima. Selain itu, nilai meanrnrank kelompok eksperimen sebesar 18,88 lebih tinggi dibandingkan kelompokrnkontrol sebesar 6,63. Dengan demikian, dapat disimpulkan bahwa kegiatanrneksperimen berpengaruh signifikan terhadap kemampuan pemecahan masalah anakrnusia 5–6 tahun di TK Dharma Wanita Persatuan 2 Kesek.

Problem-solving ability is one of the important aspects of cognitive developmentrnthat needs to be developed from an early age. One effort to improve this ability isrnthrough natural phenomenon experiment activities, which provide children withrndirect learning experiences. This study aimed to determine the effect of naturalrnphenomenon experiment activities on the problem-solving abilities of children agedrn5–6 years at TK Dharma Wanita Persatuan 2 Kesek. This study employed arnquantitative approach using a quasi-experimental method with a NonequivalentrnControl Group Design. The sample consisted of 25 children, including 13 childrenrnin the experimental group and 12 children in the control group. Data were collectedrnthrough observation using a valid and reliable research instrument. Data werernanalysed using the Mann–Whitney U Test because the sample size was fewer thanrn30 children. The results showed that the Asymp. Sig. (2-tailed) value was 0.000 <rn0.05, indicating that H₀ was rejected and Hₐ was accepted. In addition, the meanrnrank of the experimental group (18.88) was higher than that of the control grouprn(6.63), indicating that experiment activities had a significant effect on the problem-rnsolving abilities of children aged 5–6 years at TK Dharma Wanita Persatuan 2rnKesek.
