Abstract

The problem of disposable diaper waste is a serious problem that challenges the environment. Therefore, researchers are trying to use diaper waste in agriculture. Literature studies have been carried out as a form of scientific articles. The aim of this literature review are determine the absorption ability of Super Absorbent Polymers (SAP) on the effect of pH, temperature, salinity and soil moisture with the addition of Super Absorbent Polymer (SAP). This study was expected to increase knowledge about Super Absorbent Polymer (SAP) and its application related to the agricultural sector. From the results of the literature study, it was concluded that the swelling ability of the SAP reached the optimum conditions at pH 6.5 and 9, while the influence of temperature on the swelling ability of the SAP occurred at temperatures of 25oC, 50oC and 75oC. Swelling capacity conditions using saline solution showed a decrease in swelling capacity as the concentration of the salt solution increased. Soil moisture by adding super absorbent polymer showed significant results, which was 3 times higher than without SAP, i.e. moisture could last up to 18 days from the first day of watering but not for all types of plants.

Abstract

Given the existence of plastic waste in the environment is very dangerous, therefore it is necessary to conduct research to handle it. The development of technology for plastic processing to produce something useful continues to be carried out by various groups, ranging from scientists, academics, and students. One of them is the utilization of plastic waste into fuel oil (BBM) using the pyrolysis technique which will be installed to process plastic waste. The purpose of this study was to determine the fuel oil from processing plastic waste and compare the fuel with kerosene and diesel oil with the parameters of density, burning time and water temperature when heating using the three fuel oils. The research method used is data collection techniques including pre-treatment, the process to determine the density of each fuel sample, the process of burning time, temperature during heating, analysis of the density of pyrolysis oil, kerosene and diesel fuel by measuring the volume and the mass of each sample. Comparison of the quality of Fuel Burning Time, namely Oil from recycled plastics 4.01 minutes, Diesel Oil 4.45 minutes, and Kerosene 3.02 minutes. Comparison of the quality of water temperature with a volume of 20 ml of water and a heating time of 5 minutes, it is found that recycled plastic oil is 0.77oC, diesel oil is 0.73oC, kerosene is 0.84oC. plastic waste processing is under kerosene but above diesel oil based on density indicators, burning time, water temperature when heating.

Abstract

The problem of disposable diaper waste is a serious problem that challenges the environment. Therefore, the researchers sought the utilization of diaper waste in agriculture. Efficiency of fertilizer absorption in plants in the environment by 30-40%, remaining in the air and evaporating into ammonia gas. Utilization of baby diaper waste as a matrix and urea as a filler was carried out in this study. This is expected to be able to control the release of nitrogen in fertilizers in accordance with the amount and amount needed by plants (desorption) and maintain nitrogen requirements in the soil, so that the amount of fertilizer given is more efficient than conventional methods. How the purpose of this research is how to make fertilizer based on diaper waste, determine Nitrogen adsorption capacity into the matrix and determine the fertilizer requirements for growing chilli seedlings. The study was divided into 5 stages, the processing of baby diaper waste; second, the manufacture of urea larvae (fillers); three, filling the filler into the matrix; Rate, determine the Nitrogen adsorption capacity into the matrix; discuss, test on plants. The research results obtained are variations in the contribution of urea used as fillers is 15%. Based on this research, it can be said that diaper waste has the potential to control the release of urea. Furthermore, it can explain the rate of release of urea in chili plants.
