Abstract

Abstrak: Media tanam pada pembibitan kelapa sawit pada umumnya terdiri atas tanah yang dicampur dengan pasir serta pupuk anorganik seperti pupuk fosfat. Bahan organik sering dimanfaatkan untuk lebih meningkatkan produktifitas media tanam. Tujuan penelitian untuk mengetahui pengaruh biochar pelepah kelapa sawit dan pemberian dosis pupuk fosfat pada pre nursery kelapa sawit. Penelitian dilaksanakan di Biochar Research Station dan Laboratorium Ilmu dan Teknologi Benih, Fakultas Pertanian, Universitas Syiah Kuala, Darussalam, Banda Aceh. Penelitian ini menggunakan rancangan acak kelompok pola faktorial 3 x 4 dengan 3 ulangan, sehingga terdapat 12 kombinasi perlakuan dan 36 satuan percobaan. Hasil penelitian menunjukkan bahwa perlakuan biochar berpengaruh sangat nayata pada pH tanah dan tidak nyata pada diameter batang, bobot basah tanaman dan berat basah akar, dosis biochar pelepah kelapa sawit terbaik terdapat pada 14 g polibag-1. Perlakuan dosis pupuk fosfat sangat nyata pada bobot basah tanaman, serta nyata pada diameter batang 90 HST, berat basah akar dan pH tanah, dosis pupuk fosfat terbaik terdapat pada 0,3 g polibag-1.Effect of Oil Palm Midrib Biochar and Phosphate Fertilizer Dosage on Pre-Nursery Growth of Oil Palm (Elaeis guineensis Jacq.)Abstract. Planting media in oil palm nurseries generally consists of soil mixed with sand and inorganic fertilizers such as phosphate fertilizers. Organic matter is often used to further increase the productivity of the growing media. The purpose of the study was to determine the effect of oil palm midrib biochar and the administration of phosphate fertilizer doses on the growth of pre-nursery oil palm. The research was carried out at the Biochar Research Station and Laboratory of Seed Science and Technology, Faculty of Agriculture, Universitas Syiah Kuala, Darussalam, Banda Aceh. This study used a 3 x 4 factorial randomized block design with 3 replications, so there were 12 treatment combinations and 36 experimental units. The results showed that the biochar treatment was very significant on soil pH and not significant on stem diameter, plant wet and wet weight of oil palm roots, the best dose of oil palm frond biochar was found in 14 g polybag-1. The treatment dose of phosphate fertilizer was very significant on the wet weight of the plant, and significantly on the stem diameter of 90 DAP, root wet weight and soil pH, the best dose of phosphate fertilizer was found at 0,3 g polybag-1.

Abstract

Abstrak. Bawang merah (Allium ascalonicum L.) ialah salah satu komoditi andalan nasional yang kebutuhannya semakin bertambah tiap tahunnya. Upaya untuk menambah produksi bawang merah bisa dilakukan dengan intensifikasi teknik budidaya, salah satu upaya tersebut yaitu dengan membenahi kualitas tanah, sehingga kondusif untuk pertumbuhan bawang merah. Hal ini bisa dilakukan dengan pemberian mulsa dan pengunaan biochar. Tujuan dilaksanakannya penelitian ini adalah mengetahui pengaruh pemberian dosis biochar dan beberapa jenis mulsa terhadap pertumbuhan dan hasil tanaman bawang merah. Penelitian ini berlangsung di Lahan Percobaan 2 Sektor Timur, Laboratorium Fisiologi Tumbuhan dan Laboratorium Hortikultura Fakultas Pertanian Universitas Syiah Kuala, Banda Aceh. Penelitian ini dilaksanakan pada bulan April sampai Juli 2022. Penelitian ini memakai Rancangan Acak Kelompok (RAK) pola faktorial 3 x 4 serta terdapat 3 ulangan. Adapun faktor yang diteliti yaitu pengaruh jenis mulsa dan dosis biochar. Hasil penelitian memperlihatkan jenis mulsa berpengaruh sangat nyata pada tinggi tanaman 21, 28, 35 serta 42 HST, jumlah anakan umur 30, 40 serta 50 HST, bobot brangskasan kering per rumpun, bobot umbi kering serta potensi hasil. Jenis mulsa terbaik dijumpai pada mulsa plastik (M2). Perlakuan dosis biochar berpengaruh sangat nyata pada tinggi tanaman 21, 28 serta 35 HST. Perlakuan dosis biochar berpengaruh nyata pada tinggi tanaman 42 HST, jumlah anakan 30 serta 40 HST, bobot brangkasan kering per rumpun, bobot umbi kering serta potensi hasil. Perlakuan terbaik dijumpai pada dosis biochar 15 ton ha-1 (B3). Perlakuan jenis mulsa dan dosis biochar limbah kayu tidak terdapat interaksi pada semua parameter yang di uji.The Effectiveness of Mulch and Wood Waste Biochar on Growth and Yield of Shallots (Allium ascalonicum L.)Abstrak. Red onion (Allium ascolonicum L.) is one of national mainstay commodities that needs are increase every year. Efforts to increase shallot production can be carried out by intensifying cultivation techniques, one of these effort is improve soil quality, so that is conducive for the growth of shallot. This can be done by providing mulch and using biochar. The purpose of this research was to determine the effect of biochar doses and several types of mulch on the growth and yield of shallot plants. This research took place at Experimental Field 2 East Sector, Plant Physiology Laboratory and Horticulture Laboratory, Faculty of Agriculture, Syiah Kuala University, Banda Aceh. This research was conducted from April to July 2022. This research used a 3 x 4 factorial Randomized Block Design (RBD) with 3 replications. The factors studied were the influence of the type of mulch and the dose of biochar. The results showed that the type of mulch had a very significant effect on plant height at 21, 28, 35 and 42 DAP, number of tillers aged 30, 40 and 50 DAP, weight of dry stover per clump, weight of dry tubers and yield potential. The best type of mulch is found in plastic mulch (M2). The treatment of biochar doses had a very significant effect on plant height at 21, 28 and 35 HST. Biochar dosage treatment had a significant effect on plant height at 42 DAP, number of tillers 30 and 40 HST, dry stover weight per clump, dry tuber weight and yield potential. The best treatment was found at a dose of 15 ton ha-1 biochar (B3). There was no interaction between the types of mulch and the dosage of wood waste biochar on all the parameters tested.
