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. Penelitian ini di susun dalam Rancangan Acak Kelompok (RAK) dengan analisis Faktorial 3 x 3 dengan 2 faktor 3 ulangan di peroleh 27 polybag sebagai berikut : Faktor pertama menggunakan ekstrak bawang merah (B) sebagai Zat Pengatur Tumbuh yang terdiri dari 4 taraf, yaitu : M150 : 150 gram/liter air, M200 : 200 gram/liter air, M250 : 250 gram/liter air, M300 : 300 gram/liter air. Faktor kedua menggunakan pupuk organik kotoran ayam dan sekam padi sebagai media tanam (M) yang terdiri dari 3 taraf, yaitu : TT : Tanah (Kontrol), TA : Tanah + Pupuk Kotoran Ayam (1 : 2), TP : Tanah + Pupuk Kotoran Ayam + Sekam Padi (2 : 1 : 1). Berdasarkan hasil analisis data menunjukkan bahwa Pemberian ekstrak bawang merah pada sambung pucuk tanaman kopi berpengaruh nyata pada hari muncul tunas, panjang tunas dan diameter batang. Interaksi pupuk Urea dan pupuk organik cair daun gamal berpengaruh nyata pada paremeter tinggi tanaman dan diameter batang. Kata Kunci : Robusta, Allium, Ekstrak

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

This study aims to determine the effect of liquid organic fertilizer (POC) from cocoa pod waste and NPK fertilizer on the growth of cocoa seedlings. The study was conducted experimentally with a completely randomized design (CRD) consisting of 5 treatments: control (without fertilizer), 100 ml/liter POC, 0.5 g/plant NPK, a combination of low-dose POC + NPK, and a combination of high-dose POC + NPK. The parameters observed included plant height, number of leaves, and stem diameter for 8 weeks. The results showed that the combination of POC from cocoa pod waste and NPK fertilizer had a significant effect on the growth of cocoa seedlings compared to single treatments. The high-dose combination gave the highest growth in all observed parameters. The use of POC from cocoa pod waste can be an environmentally friendly alternative to support the growth of cocoa plants. Keywords: Cocoa, cocoa pod skin POC, NPK fertilizer, seedling growth

Abstract

The purpose of this study was to determine the effect of Banana Peel Waste POC and Urea Fertilizer and the interaction of the two treatments on the growth of oil palm seedlings in the Pre-nursery. The study was conducted for 4 months, starting from March 2025 preparation to June 2025 the final data collection and took place at the Research Field of the Faculty of Agriculture, Widya Gama Mahakam University Samarinda, Jalan Wahid Hasyim, Sempaja Village, North Samarinda District, East Kalimantan. The research method used a Factorial Randomized Block Design (RAK) consisting of 2 factors with 3 replications. The first factor is Banana Peel Waste POC (P) which consists of 4 levels, namely: P0 (Control), P1 (50 ml/polybag), P2 (75 ml/polybag) P3 (100 ml/polybag The second factor is Urea Fertilizer (U) which consists of 4 levels, namely: U0 (Control), U1 (8 g/polybag), U2 (10 g/polybag), and U3 (12 g/polybag). The observation variables are plant height growth, stem diameter and number of leaves. The results showed that Banana Peel Waste Liquid Organic Fertilizer (POC) significantly affected all parameters at 90 days after planting (HST) with the best dose of 50 ml/polybag. Urea fertilizer significantly affected all parameters at 60 and 90 days after planting at a dose of 12 g/polybag. Meanwhile, the interaction between Banana Peel Waste Liquid Organic Fertilizer (POC) and Urea did not significantly affect all observed parameters.
