Pengaruh Dosis Kompos Limbah Kulit Kopi Terhadap Pertumbuhan Beberapa Varietas Bibit Kopi Arabika (Coffea arabika L.)

Abstract

Abstrak. Kopi merupaakan salaah satu haasil komoiditi perkebun4n yng memilki nilaii ekonoomis yng cukuup tiinggi di aantara taanaman peerkebunan laainnya dan beerperan peenting seebagai sumbeer devisa neegara. Penelitian ini bertujuan untuk mengetahui pertumbuhan beberapa varietas kopi arabika dengan menggunakan kompos limbah kulit kopi. Penelitian ini akan dilaksanakan di Batang Beranun Kecamatan Bandar Kabupaten Bener Meriah dan Laboratorium Fisiologi Tumbuhan Fakultas Pertanian Universitas Syiah Kuala Darussalam Banda Aceh pada April sampai dengan Juni 2018. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK)  pola faktorial 3 x 3 yang terdiri dari dua faktor. Adapun faktor yang diteliti adalah beberapa varietas kopi arabika (V) dan faktor kedua dosis pupuk kompos limbah kulit kopi (K). Data yang diperoleh dianalisis dengan menggunakan uji F, dilanjutkan dengan uji BNJ pada taraf 5%. Hasil penelitian menunjukan bahwa komposisi limbah kulit kopi berpengaruh nyata terhadap pertambahan jumlah daun pada umur 90 HSPT. Terdapat interaksi yang sangat nyata  pada pertambahan jumlah daun tanaman kopi arabika.

Effect of Compost Composition of Coffee Leather Waste on the Growth of Several Coffee Arabica Seed Varieties (Coffea arabica L.)

Abstrac. Effect of doses of coffee skin waste compost on the growth of several arabica coffee seed varieties. This study aims to determine the effect of doses of coffee skin waste compost and varieties of arabica coffee seedlings on the growth of coffee seedlings. This research was carried out on farmer-owned plantations and plant physiology laboratories majoring in Agrotechnology, Faculty of Agriculture, University of Aceh, Shiite University, Aceh from April to July 2018. This study used a randomized block design of factorial 3 x 3 and 3 replications, so there were 27 experimental units and continued with an honest real difference test at the level of 5% on a significant f test result. The first factor is the variety with 3 levels, namely: Ateng widows, Ateng super, and Ateng keumala varieties. The second factor is the dose of coffee skin waste compost with 3 levels, namely 25% and 50% control. The parameters observed were seedling height, stem base diameter, number of leaves, wet weighted weight and dry weighted weight. The results showed that the treatment of varieties significantly affected wet weight and dry weight at 90 HSPT and did not affect other parameters. Giving several concentrations of local microorganisms significantly affected the number of leaves of the age 8 cacao seedlings of coffee skin waste compost that had no significant effect on all observed parameters. There is no real interaction between the treatment of varieties and doses of coffee skin waste compost.
