Abstract

Tea waste is a low-cost alternative material for making adsorbent to remove methylene blue from synthetic dye wastewater perpetually. Optimization of the adsorbent process utilized Response Surface Methodology (RSM) and a continuously operating system in a fixed bed column. The independent variables in the research are X1 (bed height), X2 (contact time), and X3 (flow rate). The dependent variable is Y1 (removal efficiency) with a matrix design by Box-Behnken. The optimum condition of methylene blue (MB) B removal was found at X1=16 cm, X2=90 min, and X3=4 L/min with an adsorption efficiency of 90.45%. After the activation and adsorption of MB dye, the complete FTIR spectrum shows a distinct peak at 2933.7 cm-1. The results of the EDX analysis performed on tea waste reveal the presence of nitrogen (element N) following the adsorption process. This observation strongly suggests that the tea waste has effectively absorbed MB, as nitrogen is a constituent element found in the molecular structure of MB.

Abstract

Electrical energy is an important today. Electrical energy still comes from fossils. It is can produce carbon gas emissions and cause greenhouse gas effects. Clean energy conversion is something that must be done immediately. This clean energy conversion still has obstacles in the form of negative public views regarding new renewable energy. Negative perspective is the effectiveness of using EBT and the need for large enough land, thereby reducing agricultural land in the future. Young people are the most strategic objects in society for implementing EBT changes in the future. The problem is the lack of knowledge among young people regarding the potential use of EBT and the limited number of competent facilitators to provide material regarding EBT. Therefore, it is necessary to carry out EBT activities and inclusive values among young people to increase competence in understanding EBT. This activity is carried out with a campaign and simulation with a solar power plant works. The aim of this activity is that students are able to choose and apply EBT in community life. The activity indicator is that students can provide feedback and explain how solar power plants work.

Abstract

.Bioethanol is a pure alcoholic compound consisting of ethanol and is produced through a biomass fermentation process with the help of microorganisms.  Making bioethanol can be done using plants that contain starch, carbohydrates, glucose, and cellulose. One option is kepok banana peels.  Utilization of kepok banana peels can increase the variety of raw materials for bioethanol production which are cost-effective and easy to obtain.  This research has been done before, what has never been done is the manufacture of bioethanol using various catalysts H2SO4, hydrolysis temperature and fermentation time.  This research method uses hydrolysis, fermentation and distillation with variations in hydrolysis temperatures of 80°C, 90°C and 100°C, variations in catalyst concentration H2SO4 1 M, 2 M, 3 M with fermentation times of 5, 7, 9 days. Results of this study  the highest yield and density were obtained at the hydrolysis temperature of 90°C, the catalyst concentration of 3 M H2SO4 with a fermentation time of 9 days was 5.0432% and 0.8346 gr/ml, and the highest bioethanol content was at the hydrolysis temperature of 90°C, the catalyst concentration  2 M H2SO4 with 9 days fermentation time of 0.2884%.  The size of a grade is influenced by the length of time of fermentation and the amount of catalyst given.  The density value of the bioethanol obtained meets the Indonesian National Standard.  The results of the GC (Gas-Chromatography) test based on the highest glucose content and fermentation time at each temperature variation showed that the bioethanol content with a glucose content of 5.2%, 12.2% and 14.1% respectively at a hydrolysis temperature of 80°C  , 90°C and 100°C with catalyst concentration H2SO4 3 M and a fermentation time of 9 days, namely 1.783%, 4.024% and 5.030%.  The greater the catalytic agent used, the greater the level of glucose produced and the longer the fermentation period given, the more optimal the product will be.

Abstract

A composite is a technical material that is made by combining two or more materials that have different properties to become a new material with different properties. Natural fibers used as composite reinforcement are more environmentally friendly and biodegradable. The use of natural fibers as composite reinforcement in recent years has experienced very rapid development. One of them is pineapple leaf fiber. The aim of this research is to determine the effect of fiber volume fraction and NaOH immersion on the mechanical properties (Tensile Strength and Impact Strength) of composites reinforced with pineapple leaf fibers with an epoxy matrix. In this research, woven composites were made with variations in volume fraction and NaOH immersion time for the fibers, then tensile tests according to ASTM D-3039 standards and impact tests according to ASTM D256 standards. Based on test results with varying fiber volume fractions of 15%, 20%, and 25%, the strength results increase and decrease. The tensile strength of the composite tends to increase with increasing fiber volume fraction and NaOH immersion. However, the longer the soaking time, namely 4 hours, the tensile strength of the composite tends to decrease. The most optimal average value of tensile strength is at a fiber volume fraction of 25% with fiber soaking for 2 hours with a value of 23.07 MPa and the lowest average value of tensile strength is at a fiber volume fraction of 15% with fiber soaking for 4 hours with value 11.31 MPa. Meanwhile, the highest average impact value was owned by a composite with a fiber volume fraction of 20% without soaking, namely 0.0589 j/mm2 and the lowest impact value was with a fiber volume fraction of 20% with fiber soaking for 4 hours, namely 0.0124 j/mm2.

Abstract

This study reports on manufacturing cellulose from robusta coffee husks through a solid-liquid extraction process. A high yield of cellulose can be achieved by extraction using 3.5% HNO3 at a temperature of 100 oC with a gain of 35.4%. Meanwhile, the extraction process with 4.5% HNO3 at a temperature of 80 oC only achieved a yield of 32.8%. From the results of this study, it can be seen that the smaller the concentration of HNO3 used and the higher the temperature, the greater the yield of cellulose produced. The X-ray diffraction pattern shows high peaks appearing at an angle of 2θ around 22.5o; this area is a typical peak of the cellulose structure. High crystallinity was obtained at a concentration of 3.5% HNO3 at a temperature of 100 oC at 82.47%, while the lowest crystallinity was found at a 5.5% HNO3 concentration at a temperature of 100 oC at 74.27%. The decrease in crystallinity was caused by the high temperature and concentration of HNO3, which caused the acid to penetrate quickly into the cellulose tissue layer and hydrolyze the crystalline regions of cellulose. FT-IR analysis showed a high absorption area at 3314 cm-1 and a low absorption area at 1028 cm-1, typical of Robusta coffee husk cellulose. The absorption located around the 3314 cm-1 bands is a stretch of the –OH group and the absorption in the 1028 cm-1 band is related to the -CH2 group. SEM can show the morphology of cellulose with smaller and uniform crystal dimensions with a scale of 20 µm.
