      Abstract
      Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian pupuk pelengkap cair (PPC) terhadap produksi dan kualitas buah stroberi (Fragaria × ananassa). Faktor perlakuan yang diuji meliputi waktu aplikasi (umur buah 5 hari dan 12 hari) serta konsentrasi PPC (0%, 0,5%, 0,6%, dan 0,8%). Parameter yang diamati meliputi persentase fruit set, jumlah buah, bobot panen, ukuran buah, tingkat kelunakan, tingkat kemasaman, tingkat kandungan gula, dan kandungan vitamin C. Hasil penelitian menunjukkan bahwa waktu aplikasi tidak memberikan pengaruh nyata terhadap semua parameter yang diamati. Namun, konsentrasi PPC memberikan pengaruh signifikan pada beberapa parameter, yaitu tingkat kelunakan, tingkat kemasaman, dan tingkat kandungan gula buah. Konsentrasi PPC 0,8% menghasilkan tingkat kandungan gula tertinggi (12,40 oBx), tingkat kemasaman terendah (322,17 mg/100 g), dan buah dengan tekstur lebih padat. Parameter lainnya, seperti persentase fruit set, jumlah buah, bobot panen, ukuran buah, dan kandungan vitamin C, tidak menunjukkan perbedaan signifikan antarperlakuan. Secara keseluruhan, konsentrasi PPC 0,8% memberikan hasil terbaik dalam meningkatkan kualitas buah stroberi, terutama dari segi kandungan gula, tekstur, dan keseimbangan kemasaman. Hasil ini mendukung penggunaan PPC sebagai strategi untuk meningkatkan mutu buah stroberi dengan tetap memperhatikan faktor genetik dan lingkungan.
       
      This study aims to evaluate the effect of liquid supplementary fertilizer (PPC) on the production and quality of strawberry fruit (Fragaria × ananassa). The treatment factors tested included application time (fruit age 5 days and 12 days) and PPC concentration (0%, 0.5%, 0.6%, and 0.8%). The parameters observed included the percentage of fruit set, number of fruits, harvest weight, fruit size, softness level, acidity level, sugar content level, and vitamin C content. The results showed that the application time did not have a significant effect on all observed parameters. However, the concentration of PPC had a significant effect on several parameters, namely the level of softness, acidity, and sugar content of the fruit. The concentration of PPC 0.8% produced the highest sugar content (12.40 oBx), the lowest acidity (322.17 mg/100 g), and fruit with a denser texture. Other parameters, such as the percentage of fruit set, number of fruits, harvest weight, fruit size, and vitamin C content, did not show significant differences between treatments. Overall, the concentration of PPC 0.8% gave the best results in improving the quality of strawberries, especially in terms of sugar content, texture, and acidity balance. These results support the use of PPC as a strategy to improve the quality of strawberries while still considering genetic and environmental factors.
