ZA fertilizer waste (Ammonium sulfate) is waste generated from the industrial process of producing ZA fertilizer. The waste contains very high calcium and has the potential to be used as a raw material in the manufacture of Precipitated Calcium Carbonate (PCC). PCC with certain qualities can be developed in the field of advanced materials, with size modification into nanoparticles. One method to produce nanoparticles is using the coprecipitation method, with the help of a polymer solution. This study aims to produce Nano-PCC by finding the best conditions of CaCl2: Ethylene Glycol mole ratio and stirring speed. Nano-PCC is synthesized by reacting fertilizer waste with HCl to form a CaCl2 solution. Then, the solution is mixed with ethylene glycol to prevent particle agglomeration so that the size obtained will be smaller. The mixture is then reacted with Na2CO3 to form precipitated calcium carbonate (PCC). In this study, the variables were the mole ratio of CaCl2: ethylene glycol (1:12, 1:14, 1:18, 1:20) and stirring speed (350, 500, 650, 800, and 950 rpm). Based on PSA analysis, the Nano-PCC obtained at the smallest CaCl2: ethylene glycol ratio 1:12, stirring speed 950 rpm was 51.83 nm. Based on Scherrer’s calculations with XRD, the particle size obtained was 48.25 nm. SEM analysis showed that the crystals formed were dominated by vaterite crystals, with a size range of 55.71-607.79 nm.

Corrosion is metal damage caused by electrochemical reactions with its environment. This environment can be water, air, gas, acid solution, salt solution, and others. Metals are highly active in producing an oxide layer on the metal surface under the influence of an aerobic environment. Metal corrosion is a process where the action of the surrounding media damages metal materials by the introduction of corrosion ions. This study aims to determine the best conditions for phosphate in controlling the rate of corrosion and Knowing the inhibition of phosphate on controlling the rate of corrosion. The materials used were stainless steel 201, stainless steel 304, and phosphate as an inhibitor. Meanwhile the solution NaCl 3.5% as a corrosive media environment and distilled water. Based on this research, the best phosphate concentration in reducing the corrosion rate of stainless steel 201 and 304 is 100 ppm with a reduction in the corrosion rate of stainless steel 201 of 0.022312 mpy with an inhibition percentage of 89.68%, and a reduction in the corrosion rate of stainless steel 304 by 0.045694 mpy with the percentage of inhibition is 94.027%. The corrosion rate of 304 stainless steel is lower than that of 201 stainless steel caused by differences in the Cr element composition of each metal. Stainless steel 304 contains 18.24% Cr while stainless steel 201 contains 13.00% Cr. The lower the Cr content in stainless steel, the stainless steel will be more susceptible to corrosion.

The large amount of solid waste from bioethanol plants is regrettable if it is only used as animal feed. The solid waste has a relatively high carbohydrate content of 36.85%, which has the potential to be hydrolysed to glucose. Hydrolysis with water is slow, so a catalyst is needed to speed up the reaction. HCl hydrolysis is commonly used to convert carbohydrates to glucose. The hydrolysis process in this study involved heating at 95°C with a stirring speed of 300 rpm. The variables tested were hydrolysis time (90, 120, 150, 180, 210 minutes) and HCl concentration (1.5, 2, 2.5, 3, 3.5N). The results showed that hydrolysis time and HCl concentration had a direct effect on glucose yield. The longer the hydrolysis time and the higher the concentration used, the higher the glucose yield. The highest glucose content obtained was 23.12%, with a yield of 70.6%, obtained under the conditions of 210 minutes hydrolysis time and 3.5 N HCl concentration.

Bioplastics are plastics made from natural materials such as starch, seeds, and tubers, then added cellulose such as nata. Bioplastics are easily degraded by microorganisms or moisture. Pineapple peel is a part of pineapple fruit that has been underutilized so it ends up as waste. The high carbohydrate content in pineapple fruit skin can potentially be used as raw material for making nata, with the addition of rice washing water which contains carbohydrates, starch, vitamin B1, vitamin B6, and vitamin B3 which can be utilized by microorganisms as a medium for making nata. The resulting nata is used as raw material for making bioplastics because the cellulose content in nata is quite high. The results of the analysis of cellulose content in the nata produced amounted to 42.78%. This study aims to make bioplastics from pineapple peel nata and rice washing water that meet the Japanesse Industrial Standard (JIS). The method of making bioplastics used is the solution casting method. The variables used in making this bioplastic are 15 grams of nata, plus 3.5 grams of chitosan with 500 rpm stirring for 10 minutes at 70 °C with the addition of glycerol variations of 2; 2.5; 3; 3.5, and 4% and variations of CMC ingredients 4; 6; 8; 10 and 12%. From the results of the study, the best results of bioplastics, namely the tensile strength value of 0.51 MPa, elongation of 71.49%, water resistance of 55.61%, and biodegradation of 35.81%, were obtained in the addition of CMC 8% and glycerol added 3.5%. The results of the bioplastic SEM test obtained a very tight and fairly flat bioplastic structure. In addition, the FTIR test found that bioplastics have 5 peaks where the 5 peaks represent the forming functional groups of bioplastics such as O-H functional groups.

The bio briquette is a type of briquette that is derived from agricultural waste since it is intentionally produced using biomass charcoal. The processing of agricultural waste, such as mushroom planting material, into bio briquettes is characterized by its low cost. When bio briquettes undergo appropriate and accurate processing, they can yield briquettes of superior quality. The primary objective of this research endeavor was to generate a biobriquette using an agricultural byproduct derived from mushroom farming, while concurrently assessing the distinct attributes and properties of said biobriquette. The research utilized a total of 400 grams of waste from mushroom culture materials, together with an adhesive composed of 40 grams of starch. The briquette dough is subsequently extruded in a cylindrical shape. Subsequently, the mold briquettes are subjected to a heating process at a temperature of 80°C for 5 hours, to decrease the moisture content. The outcome of the smoke test indicates that the emission of smoke will cease after 75 seconds. In the conducted Combustion of Speed Test, the obtained findings indicate a combustion rate of 0.425 grams per minute, using an initial sample weight of 5.8 grams. The ash content yielded a reading of 10.6%.
