PENGARUH PEMUPUKAN ORGANIK SLUDGE LIMBAH TAPIOKA DAN TAKARAN NPK TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN PAKCHOY (Brassica chinensis L)
ABSTRAK Salah satu usaha untuk mengelola limbah industri sludge tapioka adalah digunakan sebagai pupuk. Penelitian ini bertujuan untuk (1) Mengetahui pengaruh pupuk organik sludge limbah tapioka terhadap pertumbuhan tinggi tanaman dan jumlah daun serta produksi tanaman pakchoy. (2) Mengetahui pengaruh takaran NPK terhadap pertumbuhan tinggi tanaman dan jumlah daun serta produksi tanaman pakchoy. (3) Mengetahui interaksi antara pemberian pupuk organik sludge limbah tapioka dan takaran dosis NPK terhadap pertumbuhan tinggi tanaman dan jumlah daun serta produksi tanaman pakchoy. Penelitian ini dilaksanakan bulan Mei - Juli 2014 di kebun percobaan Lampung. Perlakuan disusun dengan Rancangan Acak Kelompok (RAK) dengan 10 perlakuan dan 3 ulangan. Perlakuan terdiri dari A (kontrol), B ( tanpa limbah+50g NPK), C (tanpa limbah+100g NPK), D (tanpa limbah+150g NPK), E (tanpa limbah+200g NPK), F ( 5kg sludge limbah tapioka+0g NPK), G (5kg sludge limbah tapioka+50g NPK), H ( 5kg sludge limbah tapioka+100g NPK), I (5kg sludge limbah tapioka+150g NPK), J (5kg sludge limbah tapioka+200g NPK). Kehomogenitasan data dianalisis dengan Uji Barlett sementara kemenambahan data diuji dengan Uji Tukey. Selanjutnya uji nilai tengah dilakukan dengan Uji Beda Nyata Jujur (BNJ) pada taraf 5 %. Hasil penelitian menunjukkan bahwa (1) Pemberian sludge limbah tapioka 5 kg/m2 berpengaruh nyata pada semua variabel pengamatan, seperti tinggi tanaman,jumlah daun, bobot segar, dan bobot kering. (2) Pemberian Pupuk NPK dosis 100g/m2 memberikan pengaruh lebih besar pada semua variabel pengamatan. (3) Terdapat interaksi pemberian sludge limbah tapioka 5 kg/m2 dan takaran NPK 100 g/m2 pada variabel bobot segar tanaman pakchoy. Kata kunci : Pakchoy (Brassica chinensis L.), sludge limbah tapioka, pupuk NPK. ABSTRACT Lampung Province has tapioca industry which produce many waste like hard waste. This waste usually just stacked on the disposal basin and has not managed optimally. One attempt to manage agricultural waste is used as fertilizer. This purpose of the research (1) Determine the influence of sewage sludge organic fertilizer on the growth tapioca plant height and number of leaves also pakchoyproduction. (2) Determine the influence of the dose of NPK on the growth tapioca plant height and number of leaves also pakchoy production. (3) Knowing the interactions between organic fertilizer sewage sludge tapioca and size of the dose of NPK on the growth tapioca plant height and number of leaves also pakchoy production. The hypothesis proposed that (1) Disposal of Organic sludge tapioca waste fertilizer influence the growth of plant height and number of leaves and pakchoyproduction. (2) Disposal dose of NPK fertilizer influence the growth of plant height and number of leaves and pakchoy production. (3) There is interaction between Organic sludge tapioca waste fertilizer and dose of NPK fertilizer to growth of plant height and number of leaves and pakchoy production. This research was conducted from May to July 2014 and conducted in Lampung experimental garden. Treatment arranged with randomized block design (RBD) with 10 (ten) treatment and three (3) replicates. The treatment consisted of A (control), B (without waste + 50g NPK), C (without waste + 100g NPK), D (without waste + 150g NPK), E (without waste + 200g NPK), F (5kg tapioca waste sludge 0g + NPK), G (5kg sewage sludge 50g tapioca + NPK), H (sewage sludge 5kg 100g tapioca + NPK), I (sewage sludge 5kg 150g tapioca + NPK), J (sewage sludge 5kg 200g tapioca + NPK). Data were analyzed with the Bartlett test for homogeneity Tukey test to added data. Then analyzed by analysis of variance at 5% level and to test the value of the test is being conducted Honestly Significant Difference (HSD). The results of research showed (1) Provision of sewage sludge tapioca 5 kg / m2 significant effect on all the variables of observation, such as plant height, number of leaves, fresh weight and dry weight. (2) Provision of NPK dose of 100g / m2 gives greater influence on plant height, number of leaves, fresh weight and dry weight of plants pakchoy. (3) There is interaction are giving tapioca waste sludge 5 kg / m2 and NPK dose of 100 g / m2 on variable fresh weight of pakchoyplants. Keywords: Pakcoy (Brassica chinensis L.), Sludge Tapioca Waste, NPK fertilizer.
