INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 9, ISSUE 02, FEBRUARY 2020 ISSN 2277-8616 1545 IJSTR©2020 www.ijstr.org The Growth And Result Of Gogo Rice Plants (Oryza Sativa L.) With A Few Aplication Of Biofertilizerss Based On Organic Liquid Waste In Peat Soil Medium Hapsoh, Wawan, Isna Rahma Dini, Desi Ratna Sari ABSTRACT: Gogo rice plant ia able to grow in peat soil medium although it has many obstacles such as poor nutrient in pat soil. One of effort what can be done was utilized biofertilized made from local microbes that was Bacillus cereus and combination with various types of organic liquid waste. This research aims to know of effect and the best formulation with giving biofertilizers based on organic liquid waste of rice plants in peat soil medium. This research used with six treatments randomized design completely. The treatment were include six levels such as P0 (water) P1 (B. cereus without formulation) P2 (B. cereus + rice washing water) P3 (B. cereus + coconut water) P4 (B. cereus + tofu water) P5 (B. cereus + oil palm liquid waste). This research of result show that was given of biofertilizers based organic liquid waste has an effect on the panicles lenght and the percentage of pithy grains. Biofertilizers based on coconut water organic waste liquid was the best treatment for panicles length parameters and percentage of pithy grains.

Rice production in Indonesia in 2015 reported around 75,40 million tons (BPS, 2016). To increase rice production by expanding the land with utilizing peat soil. Peat soil formed by dead plants tissues that are stacked and not completely decomposed effect to waterlogging . [2] the area of peatland in Indonesian is 14.9 million hectares [3] that the area of peat soil in Riau Province is 3.9 million hectares. This land the potentially for agricultural used. Naturally it is difficult to cultivate peat soil like other plantation crops. This can be overcome to drainage by making canals so that the management of peat soils is needed by adjusting the water level. [4] the height of the peat soil water level should not be more than 40 cm so that the land is not categorized as damaged.It cause the industrial plants such as plantsation crops difficulty to grow because of the root doesn’t develop optimally. Peat soil more potentially developing the food crops such as gogo rice plants varieties in ipago eight witch have shallow roots. Peatlands have low fertility rates such as having acidic pH, low nutrient availability [5]. One step to overcome this problem is to utilize the formulation of biofertilizers based on local microbes, namely Bacillus cereus with organic liquid waste. Bacillus cereus used is a bacteria isolated from rice straw on peatland [6]. Bacillus cereus is a gram-positive bacterium that can be found in dead plants tissue and soil [7] This bacteria can production IAA hormones [8], mineralization of organic matter [9] antifungi [10] and antibacterial [11] Research result [12] that giving of consortium biofertilizers Bacillus cereus, B.thuringiensis, B. megaterium, B. pantothenticus significantly effect pod weight / plot (1240 g) weight of seed / plot (740 g) weight of skin/plot (500 g) weight of stover/plot (4 kg) rice plants. The quality of biofertilizers based on Bacillus cereus can be improved by adding organic liquid waste. This research utilizes organic waste water such as tofu liquid waste, coconut water, palm oil liquid waste and rice washing water. Organic liquid waste is one of the forms of organic waste that has not been widely used. Some waste water such as tofu water, coconut water, rice washing water and palm oil waste water contain organic compounds that can be used as a source of nutrition for microbes such as Bacillus cereus. This waste can also be used as organic fertilizer that can improve soil fertility and increase plants growth and production. Research result [13] treatment of biofertilizers formulations based on tofu liquid waste and palm oil mill effluent is the best treatment for the seed height, root volume, root canopy ratio and dry weight on oil palm seedling. Giving of few biofertilizers formulations based on organic liquid waste is expected to increase the growth and result of gogo rice plants (Oryza sativa L.) in peat soil. This research aims to know the best effect and formulation of biofertilizerss based on organic liquid waste to growth and result of gogo rice plants (Oryza sativa L.) in peat soil medium. METHODS The materials used in this study were Bacillus cereus isolates obtained from the research [6], gogo rice plants seeds varieties Inpago 9 baby polybag, polybag size 35 cm x 40 cm, liquid waste of rice washing water, tofu waste, liquid palm oil mill effluent, coconut water liquid waste, 70% alcohol, aquades, agar nutrients, nutrient bolt, dolomite, gandafan, chitin, molasses, water, NPK fertilizer, fungicides, ragent, and decis.
