Abstract

The use of biochar and NPK fertilizers in an effort to overcome the problem of inefficiency in using excessive fertilizers on the fertility of nutrients in the soil. This is because nearly 40-70% N, 80-90% P, and 50-70% K are lost to the environment without being absorbed by plants which results in leaching, degradation, and evaporation of volatile materials in the soil. The purpose of this study was to obtain the efficiency of the results of starch coating on the mixture of corncob biochar with NPK fertilizer through a coating method which functions to bind the content of biochar and NPK fertilizer which has been coated with starch in the soil so that it does not evaporate easily when exposed to sunlight and also so that fertilizer is more hold for a long time so that it is not easily carried away by water erosion. The variables determined were NPK fertilizer content of 10%, 20%, and 30% of the weight of the corncob biochar and the concentration of starch as a coating of 10%, 20%, and 30%. The results obtained in this study were the lowest percentage value of coating was obtained, namely 0.4256%, and the highest dissolution rate was obtained at 3600 seconds. The optimization value obtained in the Minitab analysis is at 10% NPK with a 30% starch concentration with a desirability value of 0.4983. Thus, it can be concluded that the efficiency of starch coating on biochar greatly affects the percent coating and the resulting dissolution rate.

Abstract

Indonesia is a country with large population growth. The increasing number of occupations resulted in an increased need for food. One of the efforts made to meet these needs is by increasing agricultural yields such as fertilization and farming to maintain soil fertility to obtain optimal agricultural yields. The use of corn cobs and NPK biochar has an adverse effect on plants due to changes in pH in the soil, and about 20-70% of fertilizers are degraded or washed away by groundwater, so fertilization is ineffective and efficient and will pollute the environment with N content, P and K. This study aims to analyze the ash content of corn cobs biochar with NPK fertilizer using the coating method. The coating is a process for coating material by wrapping, soaking, or spraying it to provide resistance to the material and provide protection against the material. The raw material used is corn cobs biochar. The variables determined were a mixture of biochar and NPK fertilizer: 10%, 20%, and 30% with starch concentrations of 10%, 20%, and 30%. The results of the analysis obtained the lowest ash content value with the composition of biochar and NPK with a concentration of 10% coated with starch with a 30% concentration of 0.0557%. While the highest ash content was in the concentration of biochar and NPK with a concentration of 30% with a concentration of 10% starch at 0.1353%.

Abstract

Biochar is black charcoal rich in the element carbon (C) produced by the thermal decomposition of biomass at a relative temperature below 700°C without or with little oxygen, in a process called pyrolysis. Biochar can be used as an alternative soil repairer. In this research, biochar and NPK will be mixed because NPK is a fertilizer that contains complete nutrients. The aim of this research is to determine the effectiveness of biochar (pukchar) and NPK fertilizers coated with starch by using the coating method for agriculture. The coating is one of the materials that serve to coat and protect the particles of substances in the raw material, protecting the material from oxygen, moisture, and light. The variables used were 10%, 20% and 30% NPK fertilizer weight and 10%, 20% and 30% starch concentrations. The results obtained in this study were the highest dissolving time of 3,600 seconds, while the highest percentage of the coating was 0.7519% at a concentration of 10% NPK and 30% starch coating. The conclusion is that good quality or effective biochar is found at a concentration of 10% NPK and 30% starch coating. This is influenced by the value of the analysis where, because the higher the starch concentration and the lower the NPK concentration, the dissolving time and the resulting coating percent will be higher.

Abstract

Rapid development occurs in the industrial sector. However, not many industries pay attention to the aspect of environmental pollution. There is a need for a higher quality handling of industrial waste disposal, by determining the standard quality of industrial liquid waste disposal including pH, COD, BOD, TSS, NH3. Ph optimization is one way that can be used to obtain better quality standards, of course, to reduce the contamination levels of COD, BOD, TSS, NH3 in this study using analysis from DIN38409 / 52, ASTM 1252, HACH 8006, and ASTM D. 1068 B. The results identified the optimal pH of used lubricating waste water purification in the analysis of BOD, COD, TSS, and NH3, namely at ph 7. with the highest percentage reduction in contamination levels from COD 97.76%, BOD 98.46%, TSS 88 , 40%, and NH3 94.32%.
