Polypropylene organoclay nanocomposite
In large exploration of nanotechnology, polymer based nanocomposite have become major area of current scientific research and industrial application. As reported, by 2009, it is estimated the market size of polymer nanocomposite for industrial purposes is about 48 million pounds. Polymer nanocomposite is invented to meet the purpose of improving the properties of the polymer itself such as mechanical properties, thermal properties, conductivity and many more. In this study, pure material of polymer, Polypropylene (PP) and Sodium (Na+) content organoclay with different ratios of PP/Na+ were synthesized by melt intercalation polymerization with the objective of producing polymer nanocomposite with enhanced mechanical properties specifically, tensile and hardness properties. The predispersed master batch of different ratio of PP/Na+ nanocomposite were shaped into a pellet form by using a twin screw extruder before molded into a dog-bone form by hot press machine. The samples are varies by weight percent starting with pure Polypropylene, 1%, 3% and 5% of cloisite Na+. The samples were characterized by Fourier Transform Infrared (FTIR) Spectroscopy, tested mechanically using Universal Testing machine for tensile properties and hardness properties via Brinell Hardness Test. FTIR studies illustrate that Na+ organoclay successfully intercalated into the Polypropylene layer. The resulting composites indicated about 70% increases in the modulus for tensile, compared to pure Polypropylene. In tensile test, a maximum load is applied on the sample until it reaches on its break point. While for hardness test it’s about 24% increases, compared to pure Polypropylene. Hardness was measured on a Rockwell type instrument modified to measure the depth of the unrecovered indentation. A good mixing process and dispersion of Na+ can ensure a high increment of the mechanical properties. Samples also need to be fully dried, so that less bubbles, which affecting the data, can be produced during hot press molding process

In actuality, our business game came about due to the fact that people need more knowledge of business as people are unaware of the inside and outside of business. Because of that, our product which is a game serves as a very simple guideline towards those who have the motivation to learn business knowledge even though it was simplified into a game. The game itself has several real-life business concepts implemented into the game itself to make it more realistic compared to other games similar to ours on the market. As a result, those who play our game will definitely gain some knowledge in business as long as they are playing the game for a long period of time. Thus our game has a very high potential as it targets those teenagers and gamers who have a business-minded personality and helps towards commercialization
Application of repetitive language style in the text of the form 4 novel of Lieutenant Adnan by Abdul Latip Talib
This study aims to explore the application of the repetitive language style found in the novel Lieutenant Adnan by Abdul Latip Talib. The first objective of this study is to identify the application of repetition language style which includes six different types namely anaphora, epiphora, simplok, response, woordopname and parallelism. The second is to identify the application of the most dominant repetitive language style found in the text of this novel. The research methodology involves qualitative research based on text analysis of Lieutenant Adnan's novel by Abdul Latip Talib. This study uses Stylistic Theory based on the views of J.J Webber (1989). The analysis of this study also involves close and careful reading of each word, phrase and sentence to identify the application of repetitive language style found in the text of this novel. The results of the study found that the application of repetitive language style consists of anaphora, epiphora, simplok, response, woordopname and parallelism. The analysis found that the author uses this repetitive language style to emphasize and develop ideas in his writing sentences. In addition, the author of this novel likes to use the language style of anaphora repetition in his writing. The impact is that the application of language style elements in the writing of a novel text is seen to be able to act as an intermediary between the author and the reader to convey thoughts or ideas to be perceived and appreciated more easily and meaningfully in addition to enriching the aesthetic value of language in the writing of a novel text
Aquaponic Monitoring System and Fish Feeding with Favoriot
Aquaponics is a farming practice that combines the benefits of hydroponics and aquaculture. An Internet of Things (IoT) aquaponics system is used to help collect vast amounts of ecological and agricultural data. An aquaponics system, including a fish tank and planting area, has been completed and set up as an experimental field. The main objectives of this project are to develop and design a monitoring system for aquaponics that can be utilised in many aspects. This project utilises Arduino, Wi-Fi shield and Android applications for monitoring purposes. A pH sensor, temperature and servo motor are used to retrieve and store the data on the Favoriot platform. The result obtained from the sensors was degree temperature, soil moisture, pH, and automatic fish feeder. The system acquires an average performance of 92.5%, considering the data receive and system functionality. In conclusion, the project can monitor the water temperature, soil moisture, pH and provide notifications through the mobile application of the aquaponic monitoring system
Evaluation of the microplastics in bivalves and water column at Pantai Teluk Likas, North Borneo, Malaysia
Microplastics (MPs) are a pervasive pollutant in the marine environment. Pantai Teluk Likas in Sabah, Malaysia is one of the most visited beaches where tourism, recreational, and fsheries activities are high in this area. Hence, the area sufers from severe pollution, particularly from plastics. This study aims to quantify the microplastic composition in terms of color, shapes, and polymer types in marine bivalves (Anadara granosa, Glauconome virens, and Meretrix lyrata) and water column samples from Pantai Teluk Likas. All samples were digested using sodium hydroxide (NaOH) and incubated in the oven for at least 48 h. Serial fltration was done for each sample before they were observed under the dissecting microscope. The microplastics were identifed and counted based on their physical attributes which were colors and shapes. The functional group of the polymers was determined using FTIR spectroscopy. Microplastics were found present in all samples collected. G. virens had the highest abundance of microplastics at 113.6±6.5 particles/g followed by M. lyrata at 78.4±3.7 particles/g. On the contrary, A. granosa had the least microplastics with an abundance of 24.4±0.6 particles/g. Meanwhile, 110.0±36.2 particles/L of microplastics were found in water column samples from Pantai Teluk Likas. Based on the analysis, fbers were the most common shape in bivalves, while fbers and flms were common in the water column. In terms of colors, black, blue, and red were a few of the most abundant colors observed in both samples. The most common polymer detected in all bivalve species and water column samples is polycarbonate (PC), followed by polymethyl methacrylate (PMMA). Future study that focuses on the correlation between microplastic abundance in the marine biota and the water column is recommended to better understand microplastic availability and exposure
The effect of chronic microplastic exposure on the growth, biochemical responses, and histological changes of the juvenile sea cucumber Holothuria scabra
Microplastics (MPs) are minuscule plastic particles less than 5 mm in size, originating from the degradation of larger plastic debris. MPs originate from various sources and pose a significant threat to the marine ecosystem. Holothuria scabra is a species of sea cucumber with high commercial value and among the organisms affected by MPs pollution. H. scabra are also crucial in maintaining a clean seabed and recycling nutrients in the ocean ecosystem. Polymethymethacrylate (PMMA), a durable and transparent plastic polymer widely used as a glass alternative in maritime and other industries. This research aimed to investigate the toxicity effects of polymethylmethacrylate-MPs on the well-being of juvenile sea cucumber H. scabra. Over a 60-day treatment period, polymethylmethacrylate MPs were exposed to the juvenile sea cucumber diet at concentrations of 0.6 MPs/g (Treatment 1), 1.2 MPs/g (Treatment 2), and 10 MPs/g (Treatment 3) while a control group which received no MPs exposure to observe changes in their growth, biochemical responses, and histological alteration. The mean weight, weight gain percentage and specific growth rate exhibited significant differences (p < 0.05) with the control group displaying the highest SGR value of 1.22 ± 0.35%. Mortality was observed in treatment 2 and 3, respectively. A disruption in enzyme activity was also observed across all treatment groups (p < 0.05). The findings of growth rates and biochemical responses were further supported by histological observation, uncovering injuries and loss of cellular components in respiratory trees and intestines. This study enhances our understanding of the toxicity mechanism associated with PMMA-MPs in deposit feeder organisms
Measurement of the Hissing-Type Noise and Vibration of the Automotive HVAC System
Noises such as hissing, humming, air-rush and compressor engagement are the common type of noises that can be induced from the automotive heating and ventilating air conditional (HVAC) system. These noises are basically generated from the effects of vibrational HVAC components. Due to this, the root cause of the noises has to be investigated for any implementation of solution. In this study, the hissing-type of noise is taken into consideration whereby the noise and vibration are measured from various HVAC components such as Evaporator Inlet and Outlet and Thermal Expansion Valve (TXV). Three types of measurement sensors are used in this study which is tri-axial accelerometer for the vibration, tachometer for the engine rpm tracking and microphone for the noise measurement. Two types of operating conditions are taken into consideration, when engine running at 850 rpm (idle) and 850-3000 rpm (tracking) conditions and a constant blower speed is applied for both conditions. the result shows that, the hissing type of noise is determined at the frequency range of 4500-5000 Hz for the both idle and running conditions, whereby the vibration at the Evaporator Inlet is the most significant compared to the Evaporator Core and TVX components. the vibration of the Evaporator Inlet shows the drastic vibration increment between 1000-1500 rpm and getting worse towards 3000 rpm. This result is validated with the 3D colour of noise waterfall analysis, whereby the hissing noise shows the dominant result in the frequency range of 4500-5000 Hz
