Permasalahan sampah yang mencemari lingkungan dapat dikurangi dengan memanfaatkan limbah kulit nanas sebagai bahan untuk pembuatan pupuk organik cair. Penelitian ini bertujuan untuk mengetahui pengaruh dari pemberian berbagai konsentrasi pupuk organik cair kulit nanas terhadap pertumbuhan dan hasil tanaman kailan (Brassica oleraceae L.). Penelitian ini dilaksanakan di Dukuh Krangkoan RT 05 RW 02, Desa Ngaliyan, Kecamatan Limpung, Kabupaten Batang dengan ketinggian tempat 276 m dpl pada Januari 2020-Maret 2020. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok Lengkap (RAKL) Non Faktorial dengan 7 taraf perlakuan yaitu: P0 : kontrol (0%), P1 : 25 mL POC/1000 mL air (2,5%), P2 : 50 mL POC/1000 mL air (5%), P3 : 75 mL POC/1000 mL air (7,5%), P4 : 100 mL POC/1000 mL air (10%), P5 : 125 mL POC/1000 mL air (12,5%), dan P6 : 150 mL POC/1000 mL air (15%). Variabel yang diamati yaitu tinggi tanaman, jumlah daun, luas daun, bobot tanaman segar, bobot tanaman kering, bobot tajuk segar, bobot tajuk kering, bobot akar segar, dan bobot akar kering. Data yang diperoleh dianalisis menggunakan uji F, apabila berpengaruh nyata dilanjutkan dengan uji Duncan’s Multiple Range Test (DMRT) pada taraf nyata 5%. Hasil penelitian ini menunjukkan bahwa pemberian pupuk organik cair (POC) kulit nanas pada konsentrasi 2,5; 5; 7,5; 10; 12,5; dan 15% tidak memberikan pengaruh yang nyata pada variabel tinggi tanaman, jumlah daun, luas daun, bobot tanaman segar, bobot tanaman kering, bobot tajuk segar, bobot tajuk kering, bobot akar segar, dan bobot akar kering.

The problem of waste that pollutes the environment can be reduced by utilizing pineapple peel waste as material for making liquid organic fertilizer. This research aims to determine the effect of giving various concentration of liquid organic fertilizer for pineapple peel on the growth and yield of kailan (Brassica oleracea L.). This research was conducted in Krangkoan Hamlet RT 05 RW 02, Ngaliyan Village, Limpung District, Batang Regency with an altitude of 276 meters above sea level in January 2020-March 2020. The experimental design used was a Non-factorial Complete Randomized Block Design with 7 levels of treatment, namely: P0 : control (0%), P1 : 25 mL POC/1000 mL water (2,5%), P2 : 50 mL POC/1000 mL water (5%), P3 : 75 mL POC/1000 mL water (7,5% ), P4 : 100 mL POC/1000 mL water (10%), P5 : 125 mL POC/1000 mL water (12,5%), and P6 : 150 mL POC/1000 mL water (15%). The variables observed were plant height, number of leaf, leaf area, fresh plant weight, dry plant weight, fresh shoot weight, dry shoot weight, fresh root weight, and dry root weight. The data obtained were analyzed using F test, if the significant effect was followed by the Duncan’s Multiple Range Test (DMRT) test at the 5% real level. The results of this research indicate that the application of pineapple peel liquid organic fertilizer at a concentration  2,5; 5; 7,5; 10; 12,5; and 15% did not have a significant effect on the variables of plant height, number of leaf, leaf area, fresh plant weight, dry plant weight, fresh shoot weight, dry shoot weight, fresh root weight, and dry root weight.
