Hypocholesterolemic Effect of Mature Leaf Extract of Sugarcane, Saccharum officinarum (Linnaeus, 1753), in Induced Rats Raamah Rosales
ASEAN Journal of Science and Engineering Vol 1, No 3 (2021): AJSE: December 2021
Publisher : Universitas Pendidikan Indonesia (UPI)

Hypercholesterolemia is a common health risk factor for various cardiovascular diseases. The use of the medicinal plant as an alternative treatment is gaining much attention due to the reported adverse effects of statins on liver and muscle toxicity. This study aimed to determine the hypocholesterolemic properties of the mature leaf of the sugarcane plant using hypercholesterolemia-induced rats. Thirty-two Sprague Dawley rats were divided into 4 groups and fed with a normal diet and a 4% high cholesterol diet. The dose conversion was based on the human dose to surface area ratio of 0.025 at 1mg/20g rat body weight. The treatment with mature leaf extract of S. officinarum significantly lowered the cholesterol levels. The hypocholesterolemic activity and percent reduction of the plant extract were comparable to the effects of a synthetic drug, Fluvastatin, in lowering the cholesterol levels. This study presents the potential of mature leaf extract of S. officinarum as an alternative therapeutic strategy for hypercholesterolemia.

Coffee beans are processed in a variety of ways such as beverages, foods, sweets, etc. Technology to sort coffee beans is still automated. We, therefore, proposed the concept of machine learning to be applied in coffee bean sorting. We consider the moisture content, size, colour, and characteristics of the coffee bean using image processing. Finally, we sorted the green coffee beans by the Thai coffee grading standards. There are three grades: A, X, and Y. Our machine has an accuracy of 85%. To improve the quality of our machines, the datasets used to train machines must be increased.

The purpose of this study was to find out the carbon influence of rice husks and wood grain as electrolyte absorbers on large voltage and battery life. The battery fabrication procedure is as follows: (1) Preparing sixteen used batteries with a 1.5 Volt voltage, (2) Making NaCl solution with percentages of 10, 20, 30, and 40%, (3) Drying rice husks and wood grain until drying, (4) Carbonizing rice husks and wood grain, (5) Smoothing rice husks and carbonated wood grain, (6) Mixing rice husk, wood grain, and electrolyte solution, (7) Remove the contents of the used battery and wash it thoroughly, (8) Insert carbon from rice husks and wood grain. (9) Perform the process of closing the battery with the battery cover, (10) Measuring the battery voltage using an Avometer. This research shows that carbon derived from rice husks and wood grain can generate electrical voltage, but the resulting voltage is still low compared to commercial batteries. In addition, batteries with electrolyte solutions that have a salt percentage of 10% provide the most voltage.

Publisher : Universitas Pendidikan Indonesia (UPI)

The purpose of this study was to investigate, analyze, and develop a landing gear mechanism. To support the analysis, we used an elephant foot analogy. Elephant, especially African elephant, is the largest terrestrial mammals living on the planet. Having enormous size and distinctive weight make them classified as one of the significant surviving species. The project mainly focused on the use of elephant foot analogy for understanding the reduction of asphalt deformation. The deformation was tested by reducing the simulated stresses. The final solution mimics elephant foot stress absorption carrying capacity, in which this can be modeled for the modified landing gearscould demonstrate the use of BIM for bridge rehabilitation.

Publisher : Universitas Pendidikan Indonesia (UPI)

Ground-penetrating radar (also referred to as GPR, ground probing radar, or georadar) is a near-surface geophysical tool with a wide range of applications. Over the past 30 years, GPR has been used successfully to aid in constraining problems in diverse fields such as archaeology, environmental site characterization, glaciology, hydrology, land mine/unexploded ordinance detection, sedimentology, and structural geology. In many cases, however, GPR surveys have been planned or executed with little or no understanding of the physical basis by which GPR operates and is constrained. As a result, many unsuccessful GPR studies have also been presented or published over the past 30 years. The objectives of this primer are to (1) provide an introduction to the important variables pertinent to GPR and (2) explain the relevant aspects of these variables in GPR acquisition, in an attempt to provide fundamental knowledge for improving GPR usage in the future.

Indonesia is one of the countries that is famous for its extensive agricultural land so it is not surprising that Indonesia is called an agrarian country. In addition, most of the population earns a living as farmers, but this does not make Indonesia the largest rice producer in the world. Apart from that, farmers in Indonesia have difficulty dealing with pests that make them suffer losses due to crop failure. This study aims to explain the benefits and effectiveness of an automatic tool that can repel farmer pests, especially rats and birds. In this tool there is a Passive Infrared Receiver sensor that functions to detect the presence of farmer pests, then the servo motor will activate the bell, and pull the bell to produce a sound that scares birds and mice. The mechanism is controlled by a microcontroller, namely Arduino ATmega 2560. This tool is an innovation from previous technologies so that farmers' problems regarding farmer pests can be solved easily.

The human population increases every year, reported from the official website of the United Nation, in 2011 the world population reached 7 billion people. Then in 2016 reached 7.4 billion people and the world population in 2020 reached 7.7 billion people. It is estimated that by 2030 it will grow to 8.5 billion people and by 2050 to reach 9.7 billion inhabitants. which makes energy needs also increase. With these facts, we design gasification stove biomass energy that aims to reduce the use of non-renewable fuels. The study aims to design a rice husks gasification stove to minimize agricultural waste. In this study, there is an innovation in tar reduction using dolomite as a catalyst. This research uses qualitative research methods that are presented descriptively. The gasification stove design is inspired by the oil stove with the addition of an iron pipe that serves as an oxygen supplier. The design of gasification stoves using rice husk as fuel was successfully carried out. This stove is proven to be one of the tools to maximize the potential of using rice husks as fuel. Finally, we hope that this research can continue to be refined in further studies to maximize the utilization of rice husk waste as renewable alternative energy.

Rubber tyre waste is a huge burden on environmental system. In the present study, performance of gravity retaining wall system is assessed, both in deterministic and probabilistic framework, by utilizing rubber waste mix in the backfill. In the probabilistic approach, performance of a geotechnical system is measured in terms of an index popularly called “reliability index b”, a measure of probability of success of system. Concept of response surface methodology (RSM) has been applied to establish an approximate functional relationship between input geotechnical parameters, and output response, i.e. factor of safety through numerical analysis and then reliability index b is evaluated using FORM approach. Present study demonstrates the two aspects, i.e., by considering the case of a gravity retaining wall, i.e., reliability of computed value of factor of safety and role of mixing tyre chips in improving the performance of gravity wall system

Zinc sulfide is a semiconductor that is widely used in various fields. Synthesis of zinc sulfide nanoparticles by microwave irradiation method has promising prospects because of its advantages, such as commercially available precursors, short reaction times, low operating temperatures, and produced high quantity and high-quality products. The purpose of this study was to evaluate the feasibility of the production of zinc sulfide from zinc nitrate hexahydrate and thioacetamide by microwave irradiation method. The evaluation was done from the engineering and economic perspectives. The feasibility analysis method from the engineering perspective was done by designing the initial production design on a large scale, whereas the analysis from an economic perspective was done by calculating various economic parameters (i.e., Gross Profit Margin, Cumulative Net Present Value, Internal Rate Return, Payback Period, Break Event Point, and Profitability Index). The engineering perspective showed that the production of zinc sulfide nanoparticles can be done on a large scale due to the commercial availability of materials and tools. Based on the economic evaluation, this project is ideal for an industrial scale. The profits increased over 20 years and the payback period was achieved within two years. We hope this study can provide references to readers, industry, and researchers regarding the feasibility analysis of the production of zinc sulfide nanoparticles by microwave irradiation method on a large scale.

Alzheimer’sdementia (AD) is the plague of today's world: a costly harming illness that ransacks the elder of their capacity to work and affect their recollections. Many years of research have brought about a profound comprehension of the pathological processes and a range of targets of therapy. Proteomics has contributed enormously to these advances and will keep on having a growing role in determining the nature of obsessive injuries. Moreover, proteomics (both gel-based and gel-free, mass spectrometry-based), is probably going to assume an expanding job in distinguishing biomarkers that may aid early determination and in observing movement and above all response therapy. Alzheimer's dementia is a neurodegenerative disease characterized by limited motor functions and loss of memory. Clinically it is diagnosed by accumulation of plaques in neurons and formation of NFTs by the aggregation of tau proteins. These pathological changes in the brain can be observed in preclinical stages of AD known as ASYM AD and mild cognitive dementia.
