Effects of Solid Vinasse-Based Organic Fertilizer on Some Growth Indices of Tomato Plant

Abstract

Vinasse, which is commonly referred to as stillage, is a aqueous by-product of bioethanol processing. This side-product is yielded in a very large quantity in bioethanol industry since the production of 1 L of ethanol will generate 13 L of vinasse. Hence it is become a problem of bioethanol industry since vinasse waste doesn't have economic value and harmful to the environment. This industrial waste has high COD and BOD, high acidity, and high temperature when discharged from the bottom of distillation unit. To overwhelmed this drawbacks, it is crucial to attempt the reduction of the negative characteristic of vinasse as well as production of added value of vinasse. In fact, vinasse contains a considerable amount of potassium and organic matter which is beneficial for plant growth and improving the soil fertility. Thus, in this work, vinasse was utilized as a raw material for organic fertilizer. Vinasse waste was formulated with other sugarcane industrial waste (filter cake and boiler ash), and NPK fertilizer in various composition yielding solid Organo-Mineral Fertilizer (OMF). Among all the composition of OMF, It was demonstrated that vinasse formulated with 3, 6, and 9% of NPK fulfilled the Indonesian National Standar (SNI) of solid fertilizer. Thus these types of OMF were used to fertilize tomato plant. The effects of vinasse-based OMF on some growth indices of tomato plant were examined. It was revealed that vinasse fertilizer formulated with 9% of NPK exhibited the best impact to the tomato plant growth.

Utilization of Glycerol from Biodiesel Industry By-product into Several Higher Value Products

“…The acidity (pH) of vinasse was adjusted by the addition of 40% NaOH solution until it reached pH 7 (neutral). Subsequently, vinasse was evaporated at the temperature of 100 C for 1 h to remove the water and volatile compounds content until the volume of vinasse reached 80 mL (Kusumaningtyas et al 2017). After being cooled, vinasse was then mixed with the other feedstocks as depicted in Table 10.3.…”

“…Vinasse has macro-and micronutrients including N, P, K, Ca, Mg, Fe, Mn, Zn, and Cu which are useful and required for plant to grow (Madubaru 2008). Vinasse has been used as solid organo-mineral fertilizer (Kusumaningtyas et al 2017). Vinasse can also be processed into liquid organic fertilizer through fermentation and non-fermentation process.…”

“…There are some methods of applying vinasse as organic fertilizer, such as fertigation or direct application of untreated vinasse to the soil (Jiang et al 2012), application of concentrated vinasse (Lourenço et al 2019), formulation of vinassebased organo-mineral fertilizer (Kusumaningtyas et al 2017). Fertigation is simple and easy to apply.…”

On the Way to Sustainable Peat-Free Soil Amendments

“…Several scientific groups (Dirbeba et al, 2019a;2019b;Gurgel et al, 2015;Kamalia et al, 2021;Kusumaningtyas et al, 2015;2020) have studied the process of solid OMF vinasse base. While others (Anas et al, 2007;Kusumaningtyas et al, 2017) have reported the positive impact of OMF vinasse based on the productivity of tomatoes (Solanum lycopersicum L.) and sugarcane.…”

Vinasse-Based Slow-Release Organo-Mineral Fertilizer with Chitosan-Bentonite Matrix

“…Vinasse is one of the liquid wastes produced from the bioethanol industry with the amount generated is 9-14 L/L ethanol (Kose et al, 2018). Vinasse is a potential raw material for the fertilizer due to its nutrient content such as nitrogen, phosphorus, and potassium, which can support agriculture crops growth (da Silva Paredes et al, 2014) (Kusumaningtyas et al, 2017). The utilization of vinasse as a fertilizer is gaining interest in the sugarcane biorefinery (da Silva Paredes et al, 2014).…”
