Abstract

Sayuran hidroponik identik dengan sayuran sehat . Konsumsi sayuran juga dipengaruhi oleh kualitas sayur, baik bobot maupun bentuk fisik sayuran. Serangan hama pada sayuran hidroponik seperti pakcoy mempengaruhi kualitas sayuran hidroponik dari segi fisikUsaha yang dapat dilakukan untuk mengatasi permasalahan ini salah satunya dengan menggunakan pestisida.nabati tithonia. Penggunaan bahan pestisida nabati tersebut tentu perlu dilihat respon tanaman yang dibudidayakan. Penelitian ini bertujuan Pengujian respon pertumbuhandan poduksi tanaman pakcoy hidroponik dengan pemberian berbagai konsentrasi pestisida nabati. Penelitian dilakukan dengan metode Rancangan Acak Lengkap. Sebagai perlakuan yaitu (1) Tanpa pemberian pestisida nabati tithonia, (2) Pemberian 8% pestisida nabati tithonia, dan (3)Pemberian 15% pestisida nabati tithonia. Hasil yang didapatkan pada penelitian ini antara lain Pemberian pestisida nabati tithonia dengan konsentrasi 15 persen setiap dua kali seminggu adalah metode terbaik untuk meningkatkan produksi berat segar dan intensitas serangan hama, namun, efeknya tidak nyata pada panjang, lebar, dan jumlah daun.

Abstract

The pakcoy plant (Brassica rapa L) is an agricultural crop that is relatively short-lived and can be harvested in a short time. The high use of chemical fertilizers that have the potential to damage the soil is the main problem underlying this research because of this, it is important to find fertilizers that are not only effective but also environmentally friendly. This study aims to determine the effect of the combination of gamal leaf liquid organic fertilizer and 50% NPK fertilizer on the growth and production of pakcoy (Brassica rapa L) plants. The method used was Group Random Design with 3 treatments of 100% inorganic fertilizer, 150 ml of POC + 50% NPK gamal leaves, 170ml POC of gamal leaves + 50% NPK, repeated for 9 replications. Observations observed included leaf count, leaf width, leaf length, wet weight, crown weight, root weight, and root length. Based on the results of the study, significant results were obtained in the observation of leaf length (cm) and root length (cm), while insignificant results were obtained in the observation of the number of leaves (strands), leaf width (cm), fresh weight (g), crown weight (g), and root weight (g). This study showed that the application of gamal leaves and NPK liquid organic fertilizer in combination gave results that were not significantly different from the application of pure NPK fertilizer in the observation of leaf count, leaf width, fresh weight, crown weight, and root weight, but showed significant differences in leaf length and width. The results of this research can be used as a reference to improve soil conditions and support sustainable agriculture that is environmentally friendly.
