Pengaruh Dosis Biochar Limbah Kelapa Muda dan Kompos terhadap Pertumbuhan dan Hasil Tanaman Okra (Abelmoschus esculentus L. Moench.)

Abstrak. Tanaman Okra (Abelmoschus esculentus L. Moench.) merupakan jenis sayuran dari famili Malvaceae yang bermanfaat bagi tubuh serta mengandung serat tinggi, mineral, serta vitamin. Budidaya tanaman okra umumnya dibudidayakan pada ketinggian 0-800 mdpl serta dapat tumbuh disemua jenis tanah, namun pertumbuhan okra juga dipengaruhi oleh faktor tanah serta unsur yang terdapat didalam tanah. Tujuan penelitian ini mengetahui dosis biochar limbah kelapa muda dan kompos yang optimal serta interaksinya terhadap produksi tanaman okra. Pelaksanaan penelitian tersebut dilakukan di Kebun Percobaan Campus Experimental Site the ACIAR Project USK Darussalam, Banda Aceh. Penelitian ini dilakukan di polibag ukuran 50 cm x 50 cm berdasarkan metode Rancangan Acak Kelompok (RAK) pola fakorial 3 kali pengulangan. Penelitian ini terdiri dari dua faktor yaitu dosis biochar limbah kelapa muda (B) dan dosis kompos (K). Masing-masing dosis biochar limbah kelapa muda (B) dan dosis kompos (K) terdiri atas 3 taraf  yaitu 0 t ha-1, 10 t ha-1, 20 t ha-1. Parameter yang diamati tinggi tanaman, diameter pangkal batang, jumlah buah pertanaman, berat buah pertanaman, panjang buah, diameter buah dan potensi hasil. Hasil penelitian menunjukkan bahwa, penggunaan biochar dan kompos tidak mempengaruhi pertumbuhan dan produksi tanaman okra. Interaksi yang tidak terjadi antara dosis biochar limbah kelapa muda dan kompos terdapat parameter tinggi tanaman, diameter pangkal batang, jumlah buah per tanaman, berat buah per tanaman, panjang buah, diameter buah, dan potensi hasil. Meskipun tidak berpengaruh nyata, pemberian biochar 10 t ha-1 dan kompos 10 t ha-1 menghasilkan pertumbuhan dan produksi yang baikterhadap tanaman okra.Effect of Young Coconut Waste Biochar and Compost Dosage on Growth and Yield of Okra (Abelmoschus esculentus L. Moench.) Plants Abstract. The Okra plant (Abelmoschus esculentus L. Moench.) is a type of vegetable from the Malvaceae family which is beneficial for the body and contains high fiber, minerals and vitamins. Okra cultivation is generally cultivated at an altitude of 0-800 meters above sea level and can grow in all types of soil, but okra growth is also influenced by soil factors and the elements contained in the soil. The aim of this research is to determine the optimal dosage of young coconut waste biochar and compost and their interaction on okra plant production. The research was carried out at the ACIAR Project USK Darussalam Campus Experimental Site Experimental Garden, Banda Aceh. This research was carried out in polybags measuring 50 cm x 50 cm based on the Randomized Group Design (RAK) method with a factorial pattern of 3 repetitions. This research consisted of two factors, namely the dose of young coconut waste biochar (B) and the dose of compost (K). Each dose of young coconut waste biochar (B) and compost dose (K) consists of 3 levels, namely 0 t ha-1, 10 t ha-1, 20 t ha-1. The parameters observed were plant height, stem base diameter, number of fruit per plant, weight of fruit per plant, fruit length, fruit diameter and yield potential. The research results showed that the use of biochar and compost did not affect the growth and production of okra plants. Interactions that did not occur between the dose of young coconut waste biochar and compost were the parameters of plant height, stem base diameter, number of fruit per plant, fruit weight per plant, fruit length, fruit diameter, and yield potential. Even though it had no real effect, the provision of 10 t ha-1 biochar and 10 t ha-1 compost resulted in good growth and production of okra plants.
