Cabai hias (Capsicum annuum L.) merupakan salah satu komoditas hortikultura yang memiliki nilai estetika tinggi serta dapat dimanfaatkan sebagai tanaman hias maupun tanaman konsumsi. Keragaman bentuk tanaman, warna buah, dan produktivitasnya menjadikan cabai hias semakin diminati. Peningkatan pertumbuhan dan hasil tanaman dipengaruhi oleh penerapan teknik budidaya yang tepat, salah satunya melalui pemberian pupuk organik cair (POC). POC Aminosan Gold Nutrisi mengandung unsur hara makro, mikro, serta asam amino yang berperan dalam mendukung pertumbuhan vegetatif dan generatif tanaman. Namun, informasi mengenai respons beberapa varietas cabai hias IPB terhadap aplikasi POC tersebut masih terbatas. Oleh karena itu, penelitian ini bertujuan untuk mengetahui pengaruh pemberian POC terhadap pertumbuhan dan hasil cabai hias (Capsicum annuum L.). Penelitian ini dilaksanakan di Desa Blang Krueng, Kecamatan Baitussalam, Kota Banda Aceh dan Laboratorium Genetika dan Pemuliaan Tanaman Fakultas Pertanian Universitas Syiah Kuala. Penelitian menggunakan Rancangan Acak Kelompok (RAK) nonfaktorial dengan empat varietas cabai hias IPB yaitu Nazla, Ayesha, Violeta, dan Syakira. Penelitian dibagi menjadi dua seri, yaitu seri tanpa pemberian POC Aminosan Gold Nutrisi dan seri dengan pemberian POC Aminosan Gold Nutrisi. Pada setiap seri terdapat empat perlakuan varietas yang diulang sebanyak tiga kali sehingga diperoleh 12 satuan percobaan, dengan empat tanaman pada setiap satuan percobaan atau 48 tanaman per seri. Dengan demikian, jumlah keseluruhan penelitian terdiri atas 24 satuan percobaan dengan 96 tanaman. Peubah yang diamati meliputi tinggi tanaman, diameter batang, tinggi dikotomus, lebar tajuk, panjang daun, lebar daun, jumlah buah per tanaman, panjang buah, panjang tangkai buah, diameter buah, berat per buah, dan berat buah per tanaman. Hasil penelitian menunjukkan bahwa pada kondisi tanpa pemberian POC Aminosan Gold Nutrisi, perlakuan varietas berpengaruh sangat nyata terhadap tinggi tanaman, panjang buah, dan diameter buah, serta berpengaruh nyata terhadap diameter batang. Varietas Violeta menghasilkan tinggi tanaman tertinggi dan diameter buah terbesar, sedangkan varietas Nazla menghasilkan panjang buah tertinggi. Pada kondisi pemberian POC Aminosan Gold Nutrisi, perlakuan varietas berpengaruh sangat nyata terhadap diameter batang, panjang buah, panjang tangkai buah, diameter buah, berat per buah, dan berat buah per tanaman, serta berpengaruh nyata terhadap tinggi tanaman dan jumlah buah per tanaman. Varietas Syakira menunjukkan berat buah per tanaman tertinggi dan diameter batang terbesar, sedangkan varietas Ayesha menghasilkan jumlah buah per tanaman tertinggi. Hasil penelitian ini menunjukkan bahwa respons pertumbuhan dan hasil cabai hias terhadap aplikasi POC Aminosan Gold Nutrisi berbeda pada setiap varietas sehingga varietas memiliki peranan penting dalam menentukan efektivitas aplikasi POC.

Ornamental pepper (Capsicum annuum L.) is a horticultural commodity with high aesthetic value and can be utilized both as an ornamental plant and for consumption. The diversity in plant architecture, fruit color, and productivity has led to its growing popularity. Improving plant growth and yield is influenced by appropriate cultivation techniques, including the application of liquid organic fertilizer (LOF). Aminosan Gold Nutrisi LOF contains macro- and micronutrients as well as amino acids that support both vegetative and generative plant growth. However, information regarding the response of several IPB ornamental pepper varieties to the application of this LOF remains limited. Therefore, this study aimed to determine the effect of LOF application on the growth and yield of ornamental pepper (Capsicum annuum L.). This research was conducted in Blang Krueng Village, Baitussalam District, Banda Aceh City, and at the Plant Genetics and Breeding Laboratory, Faculty of Agriculture, Syiah Kuala University. The study used a non-factorial Randomized Block Design (RBD) with four IPB ornamental pepper varieties: Nazla, Ayesha, Violeta, and Syakira. The experiment was divided into two series: a series without the application of Aminosan Gold Nutrisi LOF and a series with the application of Aminosan Gold Nutrisi LOF. Each series consisted of four variety treatments replicated three times, resulting in 12 experimental units with four plants per unit (48 plants per series). Thus, the total study comprised 24 experimental units with 96 plants. The parameters observed included plant height, stem diameter, dichotomous height, canopy width, leaf length, leaf width, number of fruits per plant, fruit length, fruit pedicel length, fruit diameter, weight per fruit, and fruit weight per plant. The results showed that without the application of Aminosan Gold Nutrisi LOF, the variety treatment had a highly significant effect on plant height, fruit length, and fruit diameter, as well as a significant effect on stem diameter. The Violeta variety produced the tallest plant height and the largest fruit diameter, while the Nazla variety produced the longest fruit length. Under the condition with Aminosan Gold Nutrisi LOF application, the variety treatment had a highly significant effect on stem diameter, fruit length, fruit pedicel length, fruit diameter, weight per fruit, and fruit weight per plant, as well as a significant effect on plant height and the number of fruits per plant. The Syakira variety exhibited the highest fruit weight per plant and the largest stem diameter, whereas the Ayesha variety produced the highest number of fruits per plant. These findings indicate that the growth and yield responses of ornamental pepper to the application of Aminosan Gold Nutrisi LOF vary among varieties, highlighting the key role of plant variety in determining the effectiveness of LOF application.
