Abstract

Produksi tanaman kopi robusta yang tinggi sangat bergantung terhadap kualitas dan kuantitas dari bahan tanam (bibit) yang ada. Oleh karena itu selama proses pembibitan seperti media tanam dan pemupukan sangat diperhatikan untuk mendapatkan hasil yang lebih maksimal kedepannya.Pupuk organik dapat berbentuk padat maupun cair. Kelebihan pupuk organik cair adalah unsur hara yang dikandungnya lebih cepat tersedia dan mudah diserap akar tanaman. Selain dengan cara disiramkan pupuk cair dapat digunakan langsung dengan cara disemprotkan pada daun atau batang tanaman (Pardosi ddk, 2014). Jayanti dkk (2019) berdasarkan hasil penelitian menunjukkan bahwa ekstrak bawang merah dengan konsentrasi 200 gram / liter air berpengaruh nyata terhadap pertumbuhan tinggi, jumlah daun dan indeks mutu bibit gaharu. Faktor lain sebagai pendukung pertumbuhan sambung pucuk bibit kopi adalah media tanam. Perlakuan komposisi media tanam 2:1:1 (tanah: pupuk kandang kotoran ayam: sekam padi) menghasilkan pertambahan tinggi tanaman, berat basah akar, berat kering akar, berat berangkasan basah dan berat berangkasan kering memberikan hasil terbaik terhadap pertumbuhan bibit kopi di polybag. (Nora dkk. 2015). Tujuan Penelitian mengetahui bagaimana pengaruh pupuk orgnik cair daun gamal dan urea terhadap pertumbuhan bibit kopi. Penelitian dilaksanakan selama 16 minggu (4 bulan) terhitung bulan Januari – Juli 2023. Penelitian dilaksanakan di Kebun Percobaan Agroteknologi Universitas Widya Gama Mahakam Samarinda.

Abstract

The growth of oil palm plants is greatly influenced by the availability of nutrients in the soil. The availability of nutrients is determined by the physical, chemical and biological properties of the soil. Marginal soils such as Ultisol have very low levels of nutrient availability. This is caused by intensive weathering processes. Therefore, it is necessary to improve soil fertility. One effort that can be made to improve the fertility of Ultisol soil so that oil palms can grow well is by adding natural fertilizer. Natural fertilizer can come from the use of plant or animal remains. One of them is the use of cow blood waste, this waste has not been widely used as a source of natural fertilizer. One type of mineral soil that is widely used as a medium for growing seeds is ultisol soil. This happens because this type of soil is spread quite widely in Indonesia. The weakness of Ultisol soil as a growing medium is that this soil generally reacts very acidly. Therefore, to increase the growth of plant seeds, a good growing medium is needed for plants. To create a good growing medium, fertilizer is needed that contains alkaline reacting substances such as Potassium (K). One type of fertilizer that contains potassium is KCl fertilizer (Nugroho, 2000). The aim of the research is to determine the effect of liquid organic fertilizer from cow's blood and gamal leaves on the growth of oil palm seedlings. The research was carried out for 20 weeks (5 months) starting from February – June 2024. The research was carried out at the Agrotechnology Experimental Garden at Widya Gama Mahakam University, Samarinda. This research was organized in a Randomized Group Design (RAK) with Factorial analysis of 2 factors with 3 replications and obtained 48 polybags as follows: Cow Blood Liquid Organic Fertilizer consisting of 4 levels, namely: D0 (No Control Treatment), D1 (80 mL /L water), D2 (100 mL/L water) D3 (120 mL/L water). The second factor is KCl (K) fertilizer which consists of 3 levels, namely: K0 (0 g/tan), K1 (0.15 g/tan) and K2 (0.30 g/tan). Data were analyzed using analysis of variance based on the F test 5% and 1%. If it has a real effect, continue with the 5% BNT test. Keywords: Cow Blood, Elaeis, KCl, Liquid Organic Fertilizer,

Abstract

Suboptimal soil conditions can lead to reduced latex production and quality. One of the main factors influencing latex production is soil fertility, where fertile soil with adequate nutrient content can enhance latex yield. One of the efforts to improve production is through proper fertilization, where the dosage and timing of phosphorus (P) and potassium (K) application must align with the needs of the rubber plant and the condition of the soil. By using appropriate P and K fertilizers, rubber farmers can increase both latex yield and quality. This research was conducted using a factorial experiment with a randomized complete block design (RCBD) and three replications. The first factor was the amount of TSP fertilizer, divided into four categories: P0 = without TSP application per tree, P1 = 175 g per tree, P2 = 200 g per tree, and P3 = 225 g per tree. The second factor was the dose of KCl fertilizer, consisting of four categories: K0 = control, K1 = 200 g per tree, K2 = 250 g per tree, and K3 = 300 g per tree. The findings indicated that TSP fertilizer application had a significant effect on dry rubber content, while KCl doses did not show a significant effect on latex volume, wet latex weight, dry latex weight, or dry rubber content. Keywords: Hevea brasiliensis, latex production, phosphorus, potassium
