Isolation of Species Specific Bacteria from Raw Nature for Porcine Gelatin Detection
Get PDFThe ability of gelatinase bacteria to hydrolyze gelatin makes them widely distributed and may have an impact on the safety and quality of gelatin manufacture. A study was conducted to find out specific species of gelatinase bacteria in 14 samples from selected sources using the agar isolation method through 1, 3 and 5% porcine gelatin. The samples are chosen from various types of soil, animal skin and water. The selection is made in the event of gelatinase activity on the agar surface. Findings were obtained with the 10 most active gelatinase bacteria characterized through culture morphology which were then isolated to see their sensitivity in the detection of Halal gelatin

Comparison of Lead-Controller and Pid-Lead Controller to Control InnoSAT Attitude System
Get PDFSpace technology advancement is gaining popularity as it is one of the measures used to gauge a nation\u27s level of development. One of the countries that is starting to develop into a nation involved in the exploration of satellite technology is Malaysia. Finding all appropriate prospective solutions is crucial. One of the problems that may occur in space is a satellite\u27s position being altered by various events. The stability and orientation of a satellite can be controlled and maintained using an attitude control system (ACS). The Malaysian Innovative Satellite (InnoSAT) nano-satellite system can be stabilized by focusing on the control method. Therefore, the purpose of this study is to improve the three axes of the control system-Roll, Pitch and Yaw. Next, two control strategies for the InnoSAT system ACS have been proposed by this study: Lead Controller and PID-Lead Controller. The simulation was done using reference inputs composed of unit step functions. In comparison to the PID-Lead Controller, research has demonstrated that the Lead Controller successfully produces lower tracking performance. The key result of the study is that a PID-Lead controller is more suitable for managing satellite attitude
A Study of a Hybrid Renewable Energy System: Solar PV And Wind Energy with Battery Storage
Get PDFHybrid renewable energy systems generate power by combining two or more renewable energy sources. Traditionally grid energy method having an intermittent failure issues which can interrupt many industrial activities. The aims of this research to implement a combination of a PV-Wind-Battery hybrid renewable energy system (HRES) using MATLAB/Simulink software. As a result, the usage of renewable energy (RE) sources such as solar PV and wind energy is required as a backup. The combination of both as a non-conventional energy can overcome the power failure issue. Because solar energy is intermittent, a hybrid energy source that combines two or more renewable sources with battery storage may help to increase the scheme\u27s effectiveness. Emphasis is given to the analysis of parameters and performance of the standalone solar PV system, which incorporates a DC-DC boost converter employing the Perturb and Observe (P&O) algorithm. The battery modelling also being addressed, where it will serve as a backup power source for the entire system. The MATLAB/Simulink simulation result shown that the input and output characteristics of the solar PV, wind turbine and battery energy storage were accurately captured and aligned with manual calculations. The implementation of the boost converter with Perturb and Observe (P&O) MPPT technique proved beneficial. The successful simulatio

Green Product Design to Reduce Environmental Impacts on Product Life Cycle: A Case Study
Get PDFSustainable design is an advanced manufacturing technique that takes into account the environment\u27s impact and resource efficiency and is seen as driving the modern manufacturing process. It is a method of developing products and services that take into account environmental, social, and economic factors from the beginning to its end-of-life. However, the current state of global furniture production, including technology and development strategies, has not been thoroughly examined. In addition, a comprehensive furniture industry sustainable manufacturing system is lacking. This paper discussed a systematic literature review on the sustainable design concept for furniture. It is based on an initial review of works of literature on the manufacturing process and implications of life cycle assessment in furniture and consists of data identification, initial screening, eligibility determination, and final inclusion. This study will serve as a guide for implementing life cycle assessment to improve environmental design, particularly for furniture manufacturing. It will also use the Design for Assembly (DFA) and Design for X (DFX) methodologies to reduce environmental impacts throughout its life cycle. In addition, it serves as a resource for global furniture companies to aid in sustainable furniture development.
 
Total Phenolic Content of Five Selected Malaysian Herbs
Get PDFMalaysian rainforests support a vast diversity of plant which approximately 15,000 plants species. These plants are diverse in chemical complexities that undoubtedly important source of bioactive compounds such as phenolic compounds. The objectives of this research are to extract and compared the total phenolic content (TPC) from Solanum lasiocarpum, Euodia redlevi, Colubrina asiatica, Ipomoea aquatica s. and Amaranthus viridis in hexane, dichloromethane (DCM) and methanol extracts respectively by using Soxhlet extractor. TPC are later determined using Folin-Ciocalteu reagent using the UV-Vis Spectrometer at 765 nm with Gallic acid as the standard. First plants were stripped, washed, and dried in an oven at 40 oC for 96 h and ground to powder and kept in a tight container until further use. Dried powders were extracted in Soxhlet extraction units with three different solvents until the solvent became colourless. Phenolic compound was measured according to the Folin-Ciocalteu method at absorbance of 765 nm using the UV-Vis Spectrometer. The statistically significant difference (p<0.05) between phenolic content among samples was analyzed by one-way ANOVA by using Microsoft excel. Results showed that Amaranthus Viridis extracted with DCM had the lowest phenolic content, which was 2.73±0.16 mg GAE/g sample. The highest phenolic content found at Ipomoea Aquatica S. which was extracted by Methanol was 50.6 mg GAE/g sample. Phenolic content for most samples shows significant differences between types of sample and types of solvent extraction. There are no significant differences between Colubrina Asiatica extract with hexane and methanol, Ipomoea Aquatica S. extract with hexane and DCM, Amaranthus Viridis extract with hexane and DCM. For hexane extraction, there are no significant differences between Solanum Lasiocarpum and Euodia Redlevi; Colubrina Asiatica and Ipomoea Aquatica S. For DCM extraction, there are no significant different between Solanum Lasiocarpum and Colubrina Asiatica; Colubrina Asiatica and Amaranthus Viridis; Euodia Redlevi and Ipomoea Aquatica S. For methanolic extract of all plants are significantly different (p<0.05) with each other.
 
Feasibility Study of Modified Patching Premix Design Using Response Surface Methodology (RSM)
Get PDFRoad patching is a short-term solution used to repair road surface fractures and to ensure the efficiency of transport functions and road user safety. The patching also prevents the road subgrade from worsening if the failure is repaired immediately. The continued surface failure caused on the road is due to high traffic loads and poor-quality construction. If the surface failure is not restored immediately, it could increase the risk to the safety of road users at a hazardous stage, mainly motorcyclists. This study uses a design thinking method to solve the problem and gain the idea. An exploratory empathy process is carried out randomly on the selected road samples. The maintenance practical procedure information carried out by local municipalities or private agencies is also studied to support the literature from previous research. The article will apply primary data as the initial review study. Furthermore, the Response Surface Methodology (RSM) application is identified to get a design model to simplify the design ratio. The result showed that the cubic model was the most equivalent and optimum with the squared R-value of 0.9886. It shows that the correlation of the selected variables is appropriate
