Lestari, Okvi Puji (2018) Pengaruh Kombinasi Pemberian Limbah Cair Industri Tahu Dan Mikoriza Arbuskula Terhadap Serapan Hara N Dan P Serta Pertumbuhan Tanaman Jagung (Zea Mays L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Limbah tahu merupakan bahan sisa dari proses pembuatan tahu yang berupa limbah padat maupun limbah cair. Industri tahu sendiri merupakan usaha di bidang pangan yang banyak terdapat di Indonesia, namun kebanyak limbah industri tahu tersebut merugikan lingkungan akibat pembuangan limbah yang tidak dikelola secara baik. Pemanfaatan limbah tersebut banyak digunakan untuk biogas ataupun pupuk organik yang dapat menambahkan unsur hara N dan P, tetapi limbah cair tahu ini banyak mengadung unsur hara N bagi tanaman dibandingkan unsur lainnya. Unsur hara P sendiri dapat memanfaatkan mikrobiologi mikoriza, dimana mikoriza sendiri memiliki manfaat bagi pertumbuhan dan produksi tanaman. Untuk itu pemanfaatan pengaplikasian mikoriza secara bersamaan dengan limbah cair industri tahu pada konsentrasi yang berbeda diharapkan dapat memberikan pengaruh terhadap ketersediaan unsur hara N dan P, serta pengaplikasian tersebut dapat mengoptimalkan pertumbuhan tanaman jagung. Penenelitian dilaksanakan mulai dari bulan Desember 2015 sampai dengan Januari 2016 berupa percobaan pot yang bertempat di rumah kaca Universitas Islam Negeri Malang, dengan menggunakan metode Rancangan Acak Lengkap (RAL) Faktorial dengan 2 kombinasi yaitu mikoriza dan limbah cair tahu. Kombinasi pertama adalah konsentrasi pemberian limbah cair industri tahu (0, 60, 80 dan 100 ml limbah cair industri tahu/100 ml air) dan kombinasi kedua adalah pemberian mikoriza (0 g/tanaman, 10 g/tanaman dan 20 g/tanaman). Berdasarkan faktor pengamatan disusun menjadi 12 perlakuan diulang 3 kali sehingga total kombinasi perlakuan yang digunakan terdapat 36 polibag. Parameter yang diamati meliputi komponen vegetatif seperti tinggi tanaman, jumlah daun, sedangkan untuk komponen kimia meliputi ketersediaan dan serapan N serta P, pH, COrganik. Limbah cair tahu dan mikoriza memberi pengaruh nyata terhadap pertumbuhan tanaman dimana berpengaruh pada tinggi tanaman dan jumlah daun. pengaruh nyata pada tinggi tanaman yaitu pada minggu 2 MST, 7 MST dan 8 MST dimana rata-rata tertinggi tanaman 2 MST yaitu 41 cm terendah yaitu 30 cm, untuk 7 MST tertinggi 86 cm terendah 71 cm, dan 8 MST tertinggi 92 cm terendah 77 cm. Sedangkan jumlah daun tanaman jagung pada pengamatan menunjukkan pada minggu 1 berbeda nyata dimana rata-rata jumlah daun paling banyak 2 helai terendah yaitu 1 helai daun. Pada minggu ke 8 rata-rata jumlah daun paling banyak 10 helai daun terendah yaitu 1 helai daun. Pemberian limbah cair tahu dengan penambahan mikoriza cukup dapat menambah serapan N dan P, dengan penambahan limbah cair tahu dan mikoriza N tanaman mencapai 2,71 g/tanaman tertinggi dibandingkan tanpa diberi perlakuan yaitu 1,76 g/tanaman. Sedangkan untuk P mencapai 45,91 g/tanaman dari tanpa perlakuan yaitu 34,37 g/tanaman.
English Abstract
Tofu waste is the residual material from the process of making tofu in the form of solid waste and liquid waste. The tofu industry it self is a business in the field of food that is widely available in Indonesia, but most of the tofu industrial waste is detrimental to the environment due to waste disposal that is not managed properly. The use of this waste is widely used for biogas or organic fertilizers which can add N and P nutrients, but this liquid waste contains a lot of N nutrients for plants compared to other elements. P nutrient elements themselves can utilize mycorrhizal microbiology, where mycorrhizae themselves have benefits for plant growth and production. For this reason, the utilization of mycorrhizal application simultaneously with tofu industrial wastewater at different concentrations is expected to have an effect on the availability of N and P nutrients, and this application can optimize the growth of corn plants. The research was carried out starting from December 2015 to January 2016 in the form of a pot experiment in the Islamic State University of Malang, using the Factorial Completely Randomized Design (RAL) method with 2 combinations of mycorrhizae and tofu liquid waste. The first combination was the concentration of tofu industry liquid waste (0, 60, 80 and 100 ml of tofu industrial waste/100 ml of water) and the second combination was the administration of mycorrhizae (0 g/plant, 10 g/plant and 20 g/plant). Based on the observation factors arranged into 12 treatments repeated 3 times so that the total combination of treatments used were 36 polybags. Parameters observed include vegetative components such as plant height, number of leaves, while for chemical components include the availability and uptake of N and P, pH, C-Organic. Tofu and mycorrhizal liquid waste has a significant effect on plant growth which affects plant height and leaf number. the significant effect on plant height was at week 2 MST, 7 MST and 8 MST where the highest average of plant 2 MST was 41 cm, the lowest was 30 cm, for 7 MST the highest was 86 cm lowest 71 cm, and 8 MST the highest 92 cm lowest 77 cm. While the number of leaves of corn plants on observations showed that in week 1 it was significantly different where the average number of leaves was the lowest 2 were 1 leaf. In the 8th week, the average number of leaves was at least 10 lowest leaves, namely 1 leaf. The introduction of tofu liquid waste with the addition of mycorrhizae was sufficient to increase N and P uptake, with the addition of tofu liquid waste and plant mycorrhizae N reached 2.71 g/plant highest compared with no treatment of 1.76 g/plant. Whereas for P reached 45,91 g / plant from without treatment which is 34,37 g/p
