Abstract

Root rot disease caused by the Ganoderma boninense fungus is a serious problem in oil palm cultivation. Initially this disease attacks mature plants, plants of the 3rd generation; but at this time Ganoderma disease has attacked immature plants and nurseries. Ganodermapathogens are soil borne. Improvement of growing conditions needs to be improved with the application of chemical fertilizers and the use of biological agents such as Trichoderma and Mycorrhizae. This study aims to determine the resistance of oil palm seeds with KCl, Trichoderma, and Mycorrhizal fertilizer treatments. The Ganoderma inoculum is infused in the form of a Rubber Wood Block (RWB). The research design was a factorial randomized block design consisting of 3 treatments, namely Trichoderma (T0, T1,T2), Mycorrhizae (M0, M1, M2), and KCl fertilizer (K0, K1, K2). There were 18 treatments with 3 replications. Observation parameters were seed height, number of leaves, roots, and attack intensity. The growth of seedlings at the 3rd and 5th months showed that the growth of seedlings was due to Ganoderma infection. Trichoderma and mycorrhizal treatment increased the number of healthy roots and crown dry weight. The treatment of KCl fertilizer only plays a role in root health. The best treatment is T1M2K1.Keywords:

Abstract

Perkebunan sawit telah menjadi perkebunan terbesar di Indonesia, salah satunya terdapat di Provinsi Sumatera Utara. Berdasarkan data Badan Pusat Statistik Provinsi Sumatera Utara menyatakan bahwa luas areal perkebunan kelapa sawit tahun 2016 adalah 417.809 ha dengan produksi TBS mencapai 5.775.631,82 ton, dan akan dihasilkan limbah Tandan Kosong Kelapa Sawit (TKKS) sebesar 23.250 ton/hari pada PKS berkapasitas 50 ton/jam. Material organik baik berupa limbah padat kelapa sawit sangat banyak tersedia dan belum dimanfaatkan secara maksimal. Bahan-bahan tersebut dapat dimanfaatkan sebagai bahan baku pembuatan biodegradable polybag yang  dapat digunakan sebagai media tanam untuk bibit tanaman semusim maupun tahunan. Penggunaan biodegradable polybag ini merupakan sebuah solusi dalam mengatasi  permasalahan lingkungan seperti akumulasi polybag plastik setelah pembibitan dan menghambat pertumbuhan tanaman akibat pelepasan polybag yang salah. Penelitian ini bertujuan untuk memodifikasi polybag organik yang telah dikembangkan sebelumnya dengan bahan utama limbah TKKS dan pelepah kelapa sawit, serta menentukan komposisi terbaik dari bahan baku tersebut dan melakukan pengujian kualitas sesuai dengan standar mutu kompos SNI. Kata kunci; Biodegradable Polybag, TKKS, Pelepah, Sifat Mekanik

Abstract

Penyakit daun gugur selalu menyerang pada saat awal pembentukan daun tanaman karet. Infeksi penyakit ini menyebabkan bentuk dan ukuran daun yang kurang sempurna. Daun yang tidak sempurna bentuknya dan transparan mempengaruhi  kemampuan fotosintesisnya dan akibatnya produksi karet tidak optimal. Tujuan penelitian adalah untuk mempelajari pengaruh aplikasi kalium dan silikon terhadap toleransi tanaman karet beberapa penyakit gugur daun (Coletotrichum sp dan Fusicoccum sp). Penelitian ini menggunakan bibit polibeg klon PB 260  umur 4 bulan yang telah dipupuk dengan N, P dan Mg (12:12:2) dengan dosis 12 gr polibeg. Penelitian ini menggunakan Rancangan Acak Kelompok dengan dua faktor yaitu dosis KCl (0, 5,8 g, dan 11,6 g per polibeg) dan dosis silikon (0, 20, 40 ml/L). Adapun parameter yang diamati pada penelitian ini yaitu intensitas serangan penyakit dan klorofil total. Hasil penelitian ini diketahui bahwa silikat cenderung meningkatkan toleransi tanaman karet terhadap Pestalotipsis sp., dan tidak berpengaruh terhadap C. autatum.

Abstract

One way to produce good seeds is from fertilization factors, both artificial fertilizers or biological fertilizers. Palm oil growing media is soil in which there are several nutrients needed by plants, one of which is Phosphor (P). The role of P in plants is important for cell growth, formation of fine roots and root hairs, strengthening the stem stands. However, there are still many P nutrients that are bound in the soil so with that one effort to overcome the low phosphate available in the soil is by utilizing a group of microorganisms. Microorganisms and organic matter, each of which can produce organic acids that chew metal in the soil so that phosphate becomes available to plants.

Abstract

Suspension media is made of natural ingredients to multiply microorganisms that can accelerate the destruction of organic matter. Banana hump contains water, iron, phosphorus, calcium, carbohydrates, calories and protein, which are potential as organic fertilizers. Application of banana weevil fertilizer is expected to increase the carrying capacity of the soil for the availability of organic matter and nutrients. The purpose of this study was to determine the best concentration or dose of organic liquid fertilizer for banana weevil on the vegetative growth of oil palm (Elaeis guineensis Jacq.) seedlings in the Main Nursery. Based on this statement, this research was compiled with the object of oil palm in the Main Nursery. This research was conducted in the Nursery Practice Garden area at STIP-AP Medan. Soil analysis was carried out at the Soil Laboratory of the Agricultural Technology Research Institute (BPTP) of North Sumatra. The time of the study was carried out for 8 months, from January 2021 - August 2021. This study used a Randomized Block Design (RAK) with 2 factors, namely Factor (1) Liquid Organic Fertilizer Banana Cobs and Factor (2) Compound Fertilizer (NPK) 16:16 :16. The treatment was repeated 3 times, with the number of samples being 2 plants so that the sample population was 54 plants. Parameters observed were seedling height, stem circumference, number of leaves, leaf width, root wet weight, shoot wet weight, shoot dry weight, root dry weight, total nitrogen nutrient content and C-organic nutrient content. The data obtained were analyzed statistically by analysis of variance (ANOVA) with 5% and 1% significant difference tests. The results showed that the treatment of banana weevil liquid organic fertilizer and compound fertilizer had no significant effect on the observed parameters. However, the biomass formed was significantly affected as indicated by the weight parameter. The availability of total nitrogen and C-organic nutrients in Ultisol soil showed a very low classification with total nitrogen values of 0.07 – 0.09% and C-organic values of 0.22 – 0.54%.
