Water hyacinth (Eichonia crassipes) is one type of aquatic plant that has a fast growth rate. As a result, sunlight is blocked from entering the water, so that aquatic biota cannot carry out the photosynthesis process perfectly.  This study aims to determine the value of C/N ratio, levels of Phosphorus (P), Potassium (K), pH, and temperature (T) in composting for 16 days with the addition of 200 mL of bioactivator effective microorganism 4 (EM4) in each reactor. Variations of raw materials used are Control Reactor (RK) containing 1.5 kg of water hyacinth; Treatment Reactor 1 (R1) contains 0.5 kg of water hyacinth + 1 kg of cow dung; Treatment Reactor 2 (R2) contains 0.5 kg of water hyacinth + 1 kg of rice bran; and Treatment Reactor 3 (R3) contains 0.5 kg of water hyacinth + 1 kg of cow dung + 1 kg of rice bran. The results showed that the combination of raw materials had an effect on the quality of the organic fertilizer produced. The combination of Treatment 3 (R3) produced organic fertilizer with the best quality, namely C/N ratio = 15.30%, pH = 7.16, macronutrient P = 4.91% and K = 8.36% which met the quality standard requirements.

This research paper focuses on re-engineering design and fabrication of a modified potable biogas digester for the production of biogas as a renewable energy source for domestic use. Digesters used around the world are commonly big in size. There is need to modify and re-engineer an existing biogas digester to fit in to modern day design for better efficiency, portability and safety. Floating drum and Flexible balloon are digesters to be modified as a thin walled pressure vessel with radius-thickness ratio  greater than 10. ASME codes and standards were used to carry out the sizing calculations, thickness and pressure calculations for the cylindrical pressure vessel shells and also calculations for the storage tank hemisphere shell. AISI 304 (Chromium-Nickel steel) is used for the vessel shell and the maximum allowable stress is 137 MPa. Weld efficiency (85%), corrosion allowance (0.02mm),  of 24 (for digester),  of 18 (for collector) and  of 20 (storage tank). 17 kg of cow dung and 34 kg of water with temperature of 32oC were the raw materials used for this research to produce a cumulative gas volume of 0.1243 m3 for 30 days. Furthermore, a bike pump is modified and used to increase methane gas pressure from 4.903 kPa to 345 kPa to suit the modern day gas cookers design and storage tank. Unlike other biogas plant, an electronic smoke alarm detector (model: Ei100) is placed 300 mm below the digester top for effective fire protection. Series of tests were performed to ensure that the constructed prototype met the specifications/standards. Such test include, smoke detector test, pressure testing, gas leak test, and a unit test run also confirmed that the aim of research was achieved.

In the development of vegetable farming by the community, there are fundamental problems which are generally carried out conventionally with the use of synthetic fertilizers and pesticides to determine the success of their farming. With the farming system, the community suffers a lot of losses because the inputs used are relatively expensive and on the other hand the products become cheap because the quality is not guaranteed. The solution to this problem is to develop bio-culture organic fertilizers and bio-urine whose raw materials are available in the region. The partner village development program aims to conduct training on the making and development of liquid organic fertilizer bio-culture and biourine to support the cultivation of organic vegetables. The method of approach applied is technology transfer (TT) and entrepreneurship capacity building (ECB) which is carried out with the Participatory Rural Approach (PRA) approach ) which in its implementation uses the method of lecture/discussion, training, making demo plotting, and assistance. The results achieved in the implementation of this program were that participants were able to make and develop liquid organic bioculture fertilizers and biourin and apply it to their farms as an alternative to chemical fertilizers

Novo Nordisk is one of the world's largest producers of enzymes, insulin and biopharmaceuticals. This production is based mainly on biotechnology and fermentation processes. The waste from the fermentation process is non-toxic, but due to the high content of nitrogen and phosphorus the waste can cause eutrophication if it is discharged in the marine environment. Novo Nordisk has developed a process in which the fermentation sludge, which constitutes a large part of the waste, is used as an organic fertilizer - NOVOsludge - in agriculture. The total amount of sludge is 500,000 m3/year, corresponding to 800,000 kg of nitrogen and 300,000 kg of phosphorus. Around 10,000 hectares of farmland benefit from this. Since a great proportion of the raw materials used in fermentation are based on agricultural products, this use is an example of re-cycling of nutrients. Investigations of the uptake of the nutrients in different types of crops are made in order to develop still more efficient uses. The system which has been developed has also contributed to new rules for the utilization of organic waste material.

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.

Andisols  are characterized  by  dominance  of  amorphous  minerals  which form strong and stable bonding with organic matter, therefore Andisols always contain high organic matter. For that reason, organic fertilizer is generally not applied  on  Andisols,  because  it  is  assumed  that  it  will  not  give   any  positive effect  on  growth  or  yield.  The  experiment  was  aimed  to  evaluate  response  of mature Kartika 1  Arabica coffee variety (seven years old) cultivated on  Andisols applied with organic matter derived from cow dung manure. The experiment was carried out at Andungsari  Experimental Station located in Bondowoso District, East  Java. Elevation of the site was 1,150 m asl., with rainfall type of C (Schmidt &  Fergusson).  The  experiment  was    arranged  according  to  completely randomized  block  design  with  four  replications  to  evaluate  effect  of  ninecombination  treatments  of  application  rates  at   application  depths  of  50,  100, and 150 cm. The  range of organic fertilizers rates were  0 - 13.5 kg/tree/year. The experiment revealed that cow dung manure applications on Arabica coffee cultivated  on  Andisols  significantly  increased  yield  at  the  average  of  33% compared  to  the  untreated  crop.  No  significant  effect  of  the  treatment  onvariables of leaf water deficit and soil moisture content during dry season and root  density.  At  range  of  application  depths  of  50  -  150  cm,  the  deeper  the organic matter applications, the higher the yield will be.Key words: Andisols, Arabica coffee, organic matter, cow dung manure
