This study focuses on the application of expanded polystyrene (EPS) and palm oil fuel ash (POFA) as replacement materials in concrete. In this study, EPS was utilized to replace fine aggregate up to 20% in the concrete mixture. One the other hand, POFA replaced cement up to 30% in the concrete mixture. The chemical properties of POFA were determined using XRD analysis and compared with cement. The mechanical properties of concrete cubes containing EPS and POFA were determined based on workability, density, water absorption and compressive strength. The performance of the concrete containing EPS and POFA was then compared with the normal concrete. As a result, the performance of the concrete containing EPS and POFA was determined.

This paper aims to develop an improved general mathematical model by focusing on human factors variables that related to the product defect in the manufacturing production line. This is because many studies found that almost 40% of total defects resulted from the operator error and the defects are usually not obvious and neglected. The objective to have defect prediction mathematical model to satisfy as early quality indicator of the manufacturing flow production line and assist the quality control team in manufacturing industries. Thus, the human factor variables will be investigate thoroughly and final model can be used to predict product defect on the line to improve product quality. Product defects quantity are identified and analyzed to determine the potential predictors for developing the mathematical model. A case study is offered that illustrates in a spice packaging semi-automated production line the effect that complexity variables have on assembly quality. By using Minitab, Multiple Regression analysis is conducted to model the relationship between the input variables towards response variables. From the analysis, the predicted data showed reasonable correlation with the observed data improved with adjusted R-Sq from 2.6% to 7.9%. Hence, the regression equation obtain is selected to be the prediction mathematical model for defects based on human factor input variables.
本文旨在通过关注与制造生产线中产品缺陷相关的人为因素变量,建立一种改进的通用数学模型。这是因为许多研究发现,几乎40%的缺陷是由操作人员的错误造成的,而这些缺陷通常不明显,被忽视了。目的建立缺陷预测数学模型,作为制造流程生产线的早期质量指标,辅助制造行业的质量控制团队。从而对人为因素变量进行深入的研究,最终的模型可以用于在线上预测产品缺陷,从而提高产品质量。对产品缺陷数量进行识别和分析,以确定潜在的预测因子,从而建立数学模型。以香料包装半自动化生产线为例,分析了复杂性变量对装配质量的影响。利用Minitab进行多元回归分析,对输入变量与响应变量之间的关系进行建模。从分析来看,预测数据与观测数据具有合理的相关性,调整后的R-Sq从2.6%提高到7.9%。因此,选择得到的回归方程作为基于人为因素输入变量的缺陷预测数学模型。

One of Covid-19 side effects was movement control order (MCO). Panic buying can be defined as the action of buying large quantities of a particular product or commodity due to sudden fears and a lockdown announcement from the government just adds fuel to the flames. This study has been done to identify the level of panic buying during movement restricted order (MCO). Panic buying is chosen as the research’s topic because it is the most obvious reaction that was shown from the public when MCO was announced and wanted to know did they practice this behavior or not. The researcher used questionnaire form to survey the level of panic buying during MCO. Google form was also used to determine the survey and the link was distributed to all social media platforms. From the survey, we gained 411 respondents, starting from age 18 and above that involved various ethnic in Malaysia. The findings show that the level of panic buying among Malaysian is very low (m=2.13).
新冠肺炎的副作用之一是运动控制命令(MCO)。恐慌性购买可以定义为由于突然的恐惧而大量购买特定产品或商品的行为,而政府的封锁公告只是火上浇油。本研究旨在确定限令(MCO)期间的恐慌性购买水平。之所以选择恐慌性购买作为研究的主题,是因为当MCO宣布并想知道他们是否实践这种行为时,公众表现出的最明显的反应。研究人员采用问卷调查的形式,调查了MCO期间的恐慌性购买水平。谷歌表格也被用来确定调查,并将链接分发到所有社交媒体平台。从调查中,我们获得了411名受访者,年龄在18岁及以上,涉及马来西亚各个种族。研究结果显示,马来西亚人的恐慌性购买水平非常低(m=2.13)。

Preference of consumer toward halal base product in vending machine in Selangor 消费者对雪兰莪州自动售货机清真基础产品的偏好
A. Ariff, H. Zulhazman, M. Nursalwani, A. M. Amizi
Vending machines have been developed since 1880s and has been continued to be customized to suit the taste and needs of consumers. Vending machines serves automatically, with a specific currency. Vending machines has become a multipurpose machine that not only able to serve food and snacks, but also serve ready to go meal and some are also equipped with microwave to heat the food and can be readily eaten right after purchase. Suppliers are becoming more efficient in placing vending machines so that consumers can have access to the particular vending machines. Globalization has brought Islamization with Vending machines. Hence many halal-based products are available, with the innovation of Halal vending machine, competing with Kosher-based product. Japan, Brunei and Malaysia are the pioneers that open the market as to the growing numbers of Muslim consumers. Fake logos and too many certified Halal logos have done nothing but increasing the doubt among the Muslim consumers and community. This study uses Knowledge Attitude and Practice (KAP) Survey Model to keep track of the behavior of the consumer. (KAP) Survey Model questionnaire was distributed to 100 consumers to study the behavior and perception towards vending machines that sell Halal-based products.
自19世纪80年代以来,自动售货机一直被开发出来,并不断被定制以适应消费者的口味和需求。自动售货机会自动提供服务,并提供特定的货币。自动售货机已经成为一种多用途的机器,不仅可以提供食品和零食,还可以提供现成的饭菜,有些还配备了微波炉来加热食物,可以在购买后立即食用。供应商在放置自动售货机方面变得越来越高效,这样消费者就可以使用特定的自动售货机。全球化带来了自动售货机的伊斯兰化。因此,随着清真自动售货机的创新,许多以清真为基础的产品可用,与以犹太洁食为基础的产品竞争。日本、文莱和马来西亚是向越来越多的穆斯林消费者开放市场的先行者。假标识和太多的认证清真标识只会增加穆斯林消费者和社区的疑虑。本研究采用知识态度与行为(Knowledge Attitude and Practice, KAP)调查模型来追踪消费者的行为。(KAP)调查模型问卷向100名消费者发放,研究消费者对销售清真产品的自动售货机的行为和认知。

Effectiveness of ethanolic and methanolic Morus nigra extracts on microbial strains 桑乙醇和甲醇提取物对微生物菌株的影响
M. Sokri, M. Hussin, K. A. Pahirulzaman, N. H. Saidan
The effectiveness of Morus nigra as natural antimicrobial agents were assessed by the ability of the crude extract to inhibit the growth of Escherichia coli, Staphylococcus aureus, Aspergillus brasiliensis, and Candida albicans. Different parts (fruit, root, leaves and stem) of M. nigra were extracted by maceration using different solvents; ethanol and methanol. The antimicrobial assays were carried out by paper disc diffusion method. M. nigra of all part extracted in ethanol were able to inhibit the growth of test microorganisms compared to, when extracted in methanol. Root and fruit extracts of M. nigra were able to inhibit the test microorganisms. The analytical analysis using HPLC-DAD was able to identify the presence of flavonoids rutin, quercetin, apigenin and kaempferol in crude extracts that correspond to inhibition zones observed. Hence, the results suggested that crude extracts from M. nigra root and fruit have antimicrobial properties to prevent the growth of test microorganisms.

Development of smart GPS-based nurse following robot 基于gps的智能护士跟随机器人的研制
A. M. Andrew, W. Faridah, W. Tan, S. Ragunathan, A. S. N. Amirah, N. Zainab, T. P. Yi
Hospital nurses regularly bring their medicines and healthcare items to the patients using trolley. They need to push or pull the cart to the patient’s beds, and then, need to bring it back to the original position many times daily. It can be tiresome for nurses because in a day, they need to treat many patients in the hospital. Thus, many devices have been invented to assist the nurses in their daily work routines. This research is focusing on developing a nurse following mobile robot that follows and carries medical items. The mobile robot is integrated with microcontroller, Global Positioning System (GPS) module, digital compass module and Bluetooth module. To use the robot, the nurse firstly needs to connect her smartphone to the robot through Bluetooth connection. Once the connection is established, the robot will start to follow the nurse. The robot can carry a maximum load of 5 kg and uses two direct current geared motors and a caster wheel to move.
医院护士定期用手推车给病人送去药品和保健用品。他们需要推或拉手推车到病人的床上,然后,每天需要多次把它拉回原来的位置。这对护士来说是很烦人的,因为在一天内,他们需要在医院里治疗很多病人。因此,发明了许多设备来帮助护士进行日常工作。此次研究的重点是开发一种护士跟随移动机器人,它可以跟随并携带医疗物品。该移动机器人集成了微控制器、全球定位系统(GPS)模块、数字罗盘模块和蓝牙模块。要使用机器人,护士首先需要将智能手机通过蓝牙连接到机器人上。一旦连接建立,机器人将开始跟随护士。该机器人可以携带5公斤的最大负载,并使用两个直流齿轮马达和一个脚轮来移动。

A. F. Kamaruzaman, A. Ismail, K. A. M. Daud, N. Jusoh
COVID 19 pandemic has shifted the way makerspace operationalize shifted from purely physical space into an online mode for design collaboration and also information dissemination. With the spirit of maker movement which emphasizes sharing, collaboration and making as the vital core of its operation while the online components of makerspace are the platform for design collaboration and innovation dissemination during the global pandemic and the future globalization of innovation. Due to the establishment and the technological advancement of the digital fabrication and open-source hardware and software which is available to the masses, online learning has been the main drive which shapes the way the online makerspace platform operationalize. While there are a lot of articles and research has been done on the sustainability and mechanism of the physical makerspace environment, there are lack of articles discussing the sustainability of the online components of makerspace. The objective of this paper is to review the operation of the online makerspace upon disseminating innovation and ideas. This concept paper will highlight the power of online makerspace upon disseminating ideas and innovation to further stimulating another innovation. The main finding of this review paper is that the dissemination of innovation can stimulate the other user to create another innovation through memory retrieval and idea transformation. © 2021 Author(s).
COVID - 19大流行改变了创客空间的运作方式,从纯粹的物理空间转变为设计协作和信息传播的在线模式。以共享、协作、制造为核心的创客运动精神为运营核心,创客空间的在线组件是全球大流行和未来创新全球化的设计协作和创新传播平台。由于数字化制造的建立和技术的进步,以及开源硬件和软件向大众开放,在线学习已经成为塑造在线创客空间平台运作方式的主要动力。虽然对实体创客空间环境的可持续性及其机制进行了大量的研究,但对创客空间网络组件的可持续性进行探讨的文章却很少。本文的目的是回顾在线创客空间在传播创新和思想方面的运作。这篇概念论文将强调在线创客空间在传播思想和创新以进一步激发另一项创新方面的力量。本综述的主要发现是创新的传播可以通过记忆检索和观念转化刺激其他使用者进行另一次创新。©2021作者。
