      Abstract
      MUHAMAD FARID. Pengaruh Aplikasi POC Limbah Kulit Kopi terhadap Pertumbuhan Bibit Setek Sambung Kopi Robusta. Dibimbing oleh MUHAMMAD IQBAL NURULHAQ. Kopi robusta (Coffea canephora) merupakan komoditas perkebunan penting di Indonesia yang memerlukan bibit berkualitas untuk mendukung peningkatan produktivitas. Pupuk organik cair (POC) limbah kulit kopi berpotensi dimanfaatkan sebagai sumber hara alternatif yang ramah lingkungan. Penelitian ini bertujuan mengetahui pengaruh aplikasi POC limbah kulit kopi robusta terhadap pertumbuhan bibit setek sambung kopi robusta serta membandingkan dosis aplikasi POC. Penelitian dilaksanakan pada Agustus–Desember 2025, di PTPN 1 Regional 5 Kebun Bangelan, Malang, Jawa Timur. Penelitian ini menggunakan Rancangan Acak Kelompok satu faktor dengan lima taraf dosis POC, yaitu 0 ml, 15 ml, 30 ml, 45 ml, dan 60 ml per tanaman dengan empat ulangan. Parameter yang diamati meliputi tinggi batang atas, jumlah daun, dan diameter batang atas. Hasil penelitian menunjukkan bahwa aplikasi POC limbah kulit kopi robusta tidak berpengaruh nyata terhadap seluruh parameter pertumbuhan bibit setek sambung kopi robusta selama periode pengamatan. Hasil ini menunjukkan bahwa pengelolaan konsentrasi dan teknik aplikasi POC masih perlu dioptimalkan untuk mendukung pertumbuhan bibit kopi robusta.
       
      MUHAMAD FARID. Effect of Coffee Cherry Peel Waste Liquid Organic Fertilizer Application on the Growth of Grafted Robusta Coffee Seedlings. Supervised by MUHAMMAD IQBAL NURULHAQ. Robusta coffee (Coffea canephora) is an important plantation commodity in Indonesia that requires high-quality seedlings to support productivity improvement. Liquid organic fertilizer (LOF) derived from coffee husk waste has the potential to serve as an environmentally friendly nutrient source. This study aimed to evaluate the effect of coffee husk LOF application on the growth of grafted robusta coffee seedlings and to compare the application rate. The experiment was conducted from August to December 2025 at the PTPN 1 Regional 5, Bangelan Estate, Malang, East Java. This research using a randomized complete block design with five LOF doses: 0 mL, 15 mL, 30 mL, 45 mL, and 60 mL every plant, with four replications. Observed variables included scion height, leaf number, and stem diameter. The results indicated that coffee husk LOF application had no significant effect on all growth parameters of grafted robusta coffee seedlings during the observation period. These findings suggest that dosage management and application techniques need further optimization to improve the growth of robusta coffee seedlings.
