2022-02-17T04:47:18+00:00

Crack Detector – The Crack Detection In The Snotty Building Based Artificial Intelligence And Image Processing Smart Solution To Structural Collapse is a device designed by the building's design team by implementing artificial intelligence science and image processing to detect the cracks and dimensions autonomous. Data obtained was sent to the user's computer in real time. The purpose of the construction of the device is to facilitate communities especially construction and construction safety committees (KKK) the building's security system hopes to detect cracks in high rise and can provide data on the level of damage, data obtained from a crack detector among other images and videos from the state of the building, the dimensions of cracks and the positions of cracks. Based on these data can be determined an ordinance of the building structure. Toolmaking begins with observing a multistory building on the campus and a literature study of both national and international journals and books. Next is the tool design using Solidworks 2020. Once the design is finished it continues to the stage of procuring the components needed to make the prototype. The building of the prototype is divided into three stages of assembly of the frame, assembly of the electronic components and program building. Once completed, the tool was tested for performance knowing.

Xylanase is an extracellular enzyme capable of hydrolyzing hemicellulose so that it can convert xylan into xylose. Xylanase enzymes can be used in the pulp and paper industry. This study aims to determine the effect of temperature, pH on enzyme production by immobilized thermophilic bacteria using rice straw xylan extract as a substrate and to see the effect of xylanase administration on the whiteness level of inked paper waste. This study was an experimental study and used a completely randomized design (CRD). Enzyme activity was measured using a spectrophotometer at a wavelength of 540 nm. Enzyme activity data were analyzed using the ANOVA test and continued with the DMRT (Duncan Multiple Range Test) further test with a level of 5% and the whiteness of the paper was determined by testing the kappa number. The results obtained were that the temperature of immobilize thermophilic bacteria using rice straw xylan extract as a substrate affected the xylanase enzyme activity with an optimum temperature of 75°C having the highest average value of enzyme activity 4.668 U/mL. Meanwhile, the optimum pH for immobilized thermophilic bacteria to produce xylanase was pH 8.5 with the highest average value of enzyme activity 4.854 U/mL. The addition of xylanase enzyme in the fermentation process of inked paper waste was able to increase the brightness of the inked paper with a lower average value of kappa number of 2.762 compared to the higher control of 5.525.

Study of Fastness, UV Protection, Deodorization and Antimicrobial Properties of Silk Fabrics Dyed with the Liquids Extracted from the Gallnuts, Areca Nuts, and Pomegranate Peels

The purpose of this research is to study the fastness, UV-protection, deodorization, and antimicrobial properties of silk fabrics dyed with liquids extracted from the gallnuts, areca nuts, and pomegranate peels. Among dyeing fastness of dyed silk fabrics, light and dry cleaning fastness wass 3-5 grade. The dyed silk fabrics in wavelenght range of 290-400 appeared UV protection. Deodorization activity of dyed silk fabrics appeared over 99%. The dyed silk fabrics showed high antibacterial activity of 99.9% agains Staphylococcus aerus and Klebsiella pneumoniae.

REED DIFFUSER FROM ENDOPHITE BACTERIAL EXTRACT MUTANTS AS INNOVATION TO OVERCOME TERMINE PEST

2022-02-17T08:10:42+00:00

Reed Diffuser from Andalas mutant endophytic bacteria extract is the latest innovation as an anti-termite in addition to its natural aroma, the aroma of this extract will prevent termites from living or doing activities around this product. parts that contain cellulose such as buildings, clothing, and paper. The preparation of this business will be carried out in a preparatory stage, namely in collaboration with partners, then the production stages start from sterilization of tools, manufacture of media, preparation of solutions, microbial rejuvenation, manufacture of starters, fermentation, extraction of fermented products and packaging later. The marketing stage is carried out with various approaches ranging from online and offline. In reality, the termite-resistant Reed Diffuser must be able to compete with other termite-killing products that only act as exterminators. The sales target for this termite-resistant Reed Diffuser product are office employees, both administrative and archiving, as well as sellers of wooden home furnishings and clothing sellers, which will be very useful for them later in preventing economic and material losses due to termites.

ANTITUBERCULOSIS EFFECTIVENESS OF ENDOPHYTIC ANDALAS MUTANT BACTERIA PRODUCS INDUCED BY UV LIGHT WILL BE CONDUCTED

2022-02-17T09:12:29+00:00

Indonesia is the 3^rd largest country in the world in cases of tuberculosis (TB) infection. Infections caused by the bacteria Mycobacterium Tuberculosis have claimed 100,000 lives per year. This death rate is expected to continue to increase due to resistance to Antituberculosis Drugs (OAT). One strategy to overcome the increasing number of resistance of M. tuberculosis bacteria to OAT is to find new and better antituberculosis active compounds. This study aims to determine the potential of Andalas Endophytic Bacteria mutated by UV light on antituberculosis activity. This research is descriptive research. The research was conducted at the Research Laboratory of the Faculty of Mathematics and Natural Sciences, Padang State University. The mutation process is carried out as a form of increasing the production of active compounds. Natural anti microbial compounds can be obtained through the fermentation process. The active compounds from the fermentation products were extracted using methanol and aquadest as solvents. Testing against M. tuberculosis using the Mycobacterium Growth Indicator Tube (MGIT) 960 System as a medium for sensitivity testing. The fermented supernatant with absolute concentration and extract of each solvent with a concentration of 75% were mixed into the MGIT 960 tube. The results showed that the length of time UV irradiation could reduce the number of endophytic bacterial cells of Andalas isolate ATB 10-6. UV light also causes changes in the morphology of mutant bacterial colonies. UV irradiation can produce mutant isolates that have better antifungal activity, where of the 8 mutant bacteria produced, 7 mutants have better antifungal activity than the wild type, and the growth of mutant bacteria is faster than the wild type.
