UTILIZATION OF TOFU AND SAGO PULP AS  ORGANIC LIQUID FERTILIZER AND ITS APPLICATION TO MUSTARD PLANT

Tofu waste and sago pulp are waste that has the potential to pollute the environment because it creates unpleasant aesthetic odors. On the other hand, this second waste still contains nutrients, especially macro nutrients, so it can be used as a material for making liquid organic fertilizer. In this study, both materials were used as liquid organic fertilizer through the fermentation process with the addition of EM4 liquid and the determination of nitrogen and phosphorus elements by the Kjheldal method and spectrophotometry. Based on the research results obtained Nitrogen levels in tofu waste, sago pulp and liquid organic fertilizer in a row: 2.2558%; 0.4236% and 0.0382%. While the phosphorus content in a row: 0.024%; 0.014%; and 0.012%. The results of the application of liquid organic fertilizer on mustard plants gave a tendency to increase plant height, leaf length, leaf width of mustard plants, but there was no addition of leaf blade for 14 days after planting

Series Of Experiments

Thirteen ryegrass (Lolium spp.) cultivars and three mixtures of cultivars were evaluated in a series of experiments over four years at two sites in south-eastern Queensland. Stands were sown at 30 kg/ha of viable seed and fertilized with 50 kgN/ha at sowing and after each defoliation. After an establishment period of 6-8 weeks, stands were defoliated every 21 d. Lolium multiflorum cv. Midmar was the highest yielding or equally highest yielding cultivar in three of the four years. Its forage production was better distributed over the full growing season (April- December) and its foliage was less affected by leaf rust (Puccinia coronata Corda) than any other single cultivar. L. rigidum cv. Wimmera was the best cultivar for early season production (before June) and the perennial cultivars (L. perenne cv. Kangaroo Valley and [L. multiflorum x L. perenne] x L. perenne cv. Grasslands Ariki) and cv. Midmar were superior late in the season (September-December). There was little difference in the performance of the other annual (L. multiflorum) cultivars before September. Grasslands Tama gave poorest late season yields. The only mixture that yielded more than its individual components was the Grasslands Tama/Grasslands Ariki combination. Its yield and the distribution of that yield were equivalent to cv. Midmar. Midmar had slightly lower nitrogen levels in the foliage than the other cultivars, but differences were not substantial. The relative ranking of ryegrass cultivars for resistance to rust was Midmar > Kangaroo Valley and Grasslands Ariki > Richmond and Tetila > Grasslands Manawa and Grasslands Paroa > Grasslands Tama, Wimmera, Tetrone and Tetralite.

Macro Nutrients

Liquid organic fertilizer is a solution from the fermentation of organic materials by involving microorganisms as a destructor of macromolecular compounds into minerals that are easily absorbed by plants. The quality of organic fertilizers is the main ingredient to get productive plants. The quality of organic fertilizer is determined by the concentration of macro nutrients such as nitrogen (N), potassium (K), and phosphorus. Getting high amounts of macronutrients fertilized organically is not easy. Macro-nutrients in organic waste with high concentrations are very difficult to obtain because each organic waste does not have all three macro-nutrients simultaneously. It takes a combination of organic waste to increase the concentration of macro nutrients in organic fertilizers. The combination of tofu whey with banana waste is one technique to obtain organic fertilizers that are high in phosphorus content. This study aims to obtain the effect and conditions of fermentation on the addition of mass of banana waste to produce optimum levels of phosphorus (P) in liquid fertilizer of tofu waste. The type of research used is pre-experimental research. The design of this study used a completely randomized design (CRD) with two factors, namely the first factor was the mass of banana waste (X) (X1 = 250 grams, X2 = 500 grams, X3 = 750 grams) and the second factor was the fermentation time (Y) (Y1 = 14 days, Y2 = 28 days, Y3 = 42 days). Determination of phosphorus content using UV-Vis spectroscopy instrument. Parameters measured were phosphorus (P) levels in liquid organic fertilizer. The independent variables in this study were the mass of banana waste and fermentation time, while the dependent variable in this study was the phosphorus content of the liquid fertilizer produced. The results of the analysis show that the phosphorus content (P) produced is X1Y1 = 0.1%, X2Y1 = 0.5%, X3Y1 = 0.09%, X1Y2 = 0.5%, X2Y2 = 2%, X3Y2 = 1.9 %, X1Y3 = 0.2%, X2Y3 = 0.5% and X3Y3 = 0.5%. There is an effect with the addition of a mass of banana waste as much as 250 grams at a 12-day fermentation time. It can be concluded that the liquid fertilizer produced has exceeded the SNI quality standard.

Composting Process

Histoplasma capsulatum (H. capsulatum) is a thermal-dimorphic fungus, the causal agent of histoplasmosis. Its presence in the environment is related with chicken manure due to their high nitrogen and phosphorus content. In Colombia, chicken manure is the most used raw material in the composting process; however, there is no information about the capacity of H. capsulatum to survive and remain viable in a composted organic fertilizer. To address this question, this study shows three assays based on microbiological culture and the Hc100 nested PCR. First, a composting reactor system was designed to transform organic material under laboratory conditions, and the raw material was inoculated with the fungus. From these reactors, the fungus was not isolated, but its DNA was detected. In the second assay, samples from factories where the DNA of the fungus was previously detected by PCR were analyzed. In the raw material samples, 3 colonies of H. capsulatum were isolated and its DNA was detected. However, after the composting process, neither the fungus was recovered by culture nor DNA was detected. In the third assay, sterilized and nonsterilized organic composted samples were inoculated with H. capsulatum and then evaluated monthly during a year. In both types of samples, the fungus DNA was detected by Hc100 nested PCR during the whole year, but the fungus only grew from sterile samples during the first two months evaluated. In general, the results of the assays showed that H. capsulatum is not able to survive a well-done composting process.

The present study investigated the effects of composted rice husk (5 and 26; 10 g/2 kg of soil/pot) on growth and biochemical parameters of sunflower plants at the 30th and 60th day of germination. Result showed significant improvement in growth and biochemical parameters of plants as compared to control plants treated with uncomposted organic fertilizer. However, the effects vary with the microbial treatments involved in the composting of rice husk like composted with T. hamatum (JUF1), bradyrhizobium sp-II (JUR2) alone, and JUF1 in combination with Rhizobium sp-I (JUR1) were found effective in improving the shoot and root lengths, total chlorophyll, carbohydrate, crude protein, and mineral (nitrogen and phosphorus) content of sunflower plants. It indicates that composted rice husk with improved total carbohydrate and protein contents may increase the soil fertility by improving its organic content.

Foliar Diagnosis

The leaf sample is a vital and critical factor in a sugarcane foliar-diagnosis program. For, no matter how accurate the chemical analyses, an accurate diagnosis of the sugarcane's fertilizer status is impossible if leaf samples are taken improperly. Variations were found in the nutrient content of the various leaves of the sugarcane plant, as well as variation within the leaf itself. Some of the variations encountered were: 1. The nitrogen and phosphorus contents of the leaf blade were higher than those of the leaf sheath; the reverse was true for potassium. 2. The nitrogen content of the leaf showed only a slight tendency to increase with increasing leaf number. Phosphorus, potassium, and sheath moisture dropped rapidly with increasing leaf number. 3. When the midrib of the leaf blade was eliminated, there was an increase in leaf-blade nitrogen and phosphorus, and a decrease in potassium content. 4. There was considerable variation in the nutrient content of the leaf as we moved from its base to tip. Nitrogen and phosphorus content increased rapidly from base to tip; the reverse was true for potassium.

An effort to minimize the environmental pollution is using that waste as a base material of organic fertilizer. This study was conducted to determine the levels of Nitrogen (N) and phosphorous (P) contained in the offal waste of mujair fish (Oreochromis mosambicus) from Lindu lake. Samples of mujair offal waste were taken from fish saler on the street Towua, Palu. Analysis of Nitrogen levels usedKjeldhal method which consists of three phases, namely destruction, distillation, and titration. On the other hand, for Phosphorus analysis was using wet digestion method, followed by absorbance measurements of samples with spectronic 20 at a wavelength of 720 nm. Based on the analysis, the average of nitrogen (N) levels in mujair offal waste was 2.78%, while the average of phosphorus (P) levels was 2.48%. From these results, it is known that mujair offal waste contains more nitrogen (N) compared to phosphorous (P). In addition, when compared to the quality standard liquid organic fertilizer N and P content in mujair offal almost meets the quality standard liquid fertilizer, where the minimum technical requirements of organic liquid fertilizer should contain a total N content of 3-6% and 3-6% P2O5.
