Abstract

The use of soilless planting media is currently increasingly in demand because land for agriculture is decreasing as a result of it being used for residential and industrial construction. One of the preferred planting media options is fiber, both natural and synthetic. This research aims to analyze publication trends regarding the use of fiber as a soilless planting medium, using bibliometric methods and mapping with the VOSviewer application. Publication data was taken from Google Scholar between 2019 and 2024, and a total of 942 documents were found during that period. Publication trends regarding the use of fiber as a soil-free planting medium fluctuate, increasing and decreasing every year. The number of documents in 2019 decreased, although not too significantly. But from 2019 to 2023 there was a soaring increase. At the beginning of 2024, interest in research on the use of fiber as a soil-free growing medium will increase rapidly, as shown by the publication of 52 publications at the beginning of the year. The results of three types of mapping show that research on fiber continues to develop along with the various types of fiber used as planting media. Therefore, further research regarding the development of fiber as a soilless growing medium is still relevant and very necessary and could be a driving force for further research to find innovations in this field.

Abstract

This Project aims to design and fabricate a Sugarcane Bud Chipping Machine. It has been observed that farmers prefer to plant sugarcane directly in the field manually, which is a cumbersome and time-consuming process. Once the problem was identified, an approach was conceptualized to provide a solution. Sugarcane Bud Chipper which cuts the sugarcane buds in smaller sizes for plantation purposes. These buds are smaller than the sugarcane sticks from earlier plantation methods. This machine incorporates various components, assembled uniquely for a desirable output.  The power needed to cut the sugarcane bud is generated from the pedal through human effort. A chain, 137 cm long, was used to link the two sprockets, one was attached to the pedal, while the other sprocket was attached to the arm of the cutting blade. The two sprockets are coupled to two shafts, which transfer force to the arm of the cutting blade. When the pedal is been paddled, mechanical energy leaves the pedal to the cutting unit. The blade holder was attached to the arm of the cutting blade. When the pedal is pressed, the shaft slickly rotates, the cutting unit moves downward and when the pedal is released, the cutting unit returns, upward through the support of the spring. The pedal-powered Sugarcane Bud Chipping Machine is easy to operate and reduces intensive labor. This machine makes operation easier and more comfortable in the process of sugarcane production for rural dwellers who do not have access to a power supply. The use of this machine will improve the economic well-being of local farmers in remote areas.

Abstract

A Circulated Fluidized Bed (CFB) boiler is a type of steam boiler with more complex phenomena of fluidization and combustion occurring in the furnace. One of the operating problems is the temperature bed which is difficult to predict. Bed temperature prediction is important as a reference to know the combustion process and heat transfer along the furnace. The purpose of this study is multivariable data analysis to predict bed temperature based on historical data. The amount of historical data is then prepared for the dataset and passes through the stages of data cleansing, visualization, exploration, and engineering judgment. The parameters selected as control variables after going through the first principal analysis are 5 parameters, namely gross power, coal feed (X1), primary air (PA) flow (X2), secondary air (SA) flow (X3), and average bed temperature (y). The dataset is then divided based on the load into 2 groups a low load of 20.03-30.00 MW and a high load of 30.01-54.41 MW. Each parameter is converted to the natural logarithm (ln) then multivariable regression is performed. The result is a low load model equation  with Root Mean Square Error (RMSE) = 23.2813 and a high load model equation  with RMSE = 4.8416. This model can be used to predict the average bed temperature at certain input conditions of coal feed, PA flow, and SA flow according to operating load. Prospects for bed temperature prediction with this multivariable can be developed using data-based machine learning so that the operating patterns obtained are more accurate and real-time forecast prediction.

Abstract

This study explores the Lewis acid/base interactions of divalent metal ions—copper (II), lead (II), and mercury (II)—with Lewis bases 2-naphthol and caffeine in an ethanol solvent. Utilizing the method of continuous variation, absorbance data were analyzed to understand these interactions. Absorbance data analyzed through Job's plot revealed distinct interaction patterns. For the copper (II) system, the Job's plot did not exhibit a maximum, indicating a lack of significant cooperative interaction, with absorbance values fluctuating without a clear pattern. In contrast, the lead (II) and mercury (II) systems demonstrated clear maxima with both 2-naphthol and caffeine, evidencing cooperative interactions. Specifically, the Job plot for lead (II) with 2-naphthol peaked at an absorbance of 1.25 at a mole ratio of 1:1, and for mercury (II) with caffeine, a maximum absorbance of 1.40 was observed at the same stoichiometry. These results indicate a 1:1 stoichiometry for the adducts formed, suggesting that the interactions of these metal ions with the bases can be described by the Eigen-Wilkins mechanism. This mechanism may thus account for the adduct formation involving the class B Lewis acids studied in a non-aqueous medium, highlighting a distinctive aspect of their chemical behavior.
