Astaxanthin was a beneficial carotenoid in the nutraceutical, food, cosmetics, and feed industries. The new astaxanthin infused topical moisturizer was developed using astaxanthin, Manuka honey, and Neutrogena Hydro Boost gel moisturizer. The astaxanthin was extracted from Haematococcus pluvialis subjected to the in-house astaxanthin extraction procedure developed by the Microalgae Research Laboratory, UiTM Puncak Alam, Selangor. Fifteen topical moisturizer samples were developed via Box-Behnken Design. The moisturizer properties were significantly influenced by astaxanthin, Neutrogena Hydro Boost gel moisturizer, and Manuka honey content based on the User Acceptance Survey done on 250 respondents. This study observed response surface regression, analysis of variance, and response optimization for appearance, aroma/smell, and texture. The optimum levels of the three factors were astaxanthin is at 1 ml, Neutrogena Hydro Boost gel moisturizer is at 20 ml, and Manuka honey must be less than 10 g which is at 0.9192g, as 69% of respondents like the composition.

Capability development can be defined as creating new competencies or enhancing current ones using available resources. This research investigates mediating effects of capability development (opportunity, innovation, and knowledge sharing) in influencing the relationship between social capital (structural, relational, and cognitive) and the success of community development projects in Malaysia. Hence, a total of 140 Malaysian farmers were selected as respondents due to their low income status and they were required to participate in Corporate Social Responsibility (CSR) initiatives based on the concept of Creating Shared Value (CSV). The respondents then evaluated the CSR programme whether it impacts their wellbeing based on their perceptions. The data were analysed by using PLS-SEM. The finding shows the importance of opportunity and information sharing in modulating the relationship between relational and community development programme efficacy. Future research will be beneficial particularly in addressing the knowledge gap in CSR's business–community ties.
能力开发可以定义为使用可用资源创建新的能力或增强当前的能力。本研究探讨了能力发展(机会、创新和知识共享)在影响社会资本(结构、关系和认知)与马来西亚社区发展项目成功之间关系中的中介作用。因此,共有140名马来西亚农民被选为受访者,因为他们的低收入状况,他们被要求参与基于创造共享价值(CSV)概念的企业社会责任(CSR)倡议。然后,受访者根据自己的看法评估企业社会责任计划是否会影响他们的福祉。采用PLS-SEM对数据进行分析。这一发现表明机会和信息共享在调节关系和社区发展方案效能之间的关系方面的重要性。未来的研究将是有益的,特别是在解决企业社会责任的商业社区关系的知识差距。

Trigonella foenum-graecum (TFG) is a significant leguminous plant with diverse pharmacological effects. However, the resistant character of this plant accounts for significant difficulties in vitro multiplication, justifying the necessity to try new techniques for in vitro propagation of this plant. Hence, this study reports the effects of BAP, NAA, and 2,4-D on in vitro callus formation of seeds. The toxicity properties of seeds, plant, and callus aqueous extracts of TFG were measured by brine shrimp assay (BSA). Callus index, frequency of callus, callus weight, and morphology of callus were recorded after 30 days of culture. No callus formation was observed in the absence of plant growth regulators. The maximum callus formation observed in the MS media containing 1.0 mg/l 2,4-D, the highest mean of the callus index (52±9.5) with 100% frequency and callus yield (0.52±0.08 g) in 30 days of culture. The highest mean of callus index (37±0 4.05) for combination hormones with 100% callusing and yield (0.37±0.02 g) in 30 days of culture by 1.0 mg/l BAA with 0.5 mg/l NAA. Seeds extract of TFG showed the highest toxicity (954.99 µg/ml), aqueous plant extract (1237.98 µg/ml), and aqueous callus extract (1801 µg/ml) from BSA. Comparing individual hormones, the highest amount of callus in TFG can be yielded 2,4-D hormone alone, and a combination of BAP and NAA can yield 100% callus.
Trigonella foenum-graecum (TFG)是一种重要的豆科植物,具有多种药理作用。然而,这种植物的抗性特性给其离体繁殖带来了很大的困难,因此有必要尝试新的离体繁殖技术。因此,本研究报道了BAP、NAA和2,4- d对种子离体愈伤组织形成的影响。采用盐水对虾法(BSA)测定了TFG的种子、植株和愈伤组织水提物的毒性。培养30 d后,记录愈伤组织指数、愈伤组织频率、愈伤组织质量和愈伤组织形态。在没有植物生长调节剂的情况下,未观察到愈伤组织的形成。在含1.0 mg/l 2,4- d的MS培养基中愈伤组织形成最多,愈伤组织指数(52±9.5)和愈伤组织产量(0.52±0.08 g)的平均值在培养30 d时最高。以1.0 mg/l BAA + 0.5 mg/l NAA组合激素培养30 d,愈伤组织指数(37±0.4.05)和产量(0.37±0.02 g)最高,愈伤组织形成100%。TFG种子提取物的毒性最高(954.99µg/ml),其次是植物水提取物(1237.98µg/ml)和愈伤组织水提取物(1801µg/ml)。与单个激素相比,单独使用2,4- d激素的TFG愈伤组织产量最高,BAP和NAA联合使用的愈伤组织产量可达100%。

The use of commercial media to support probiotic bacterial growth is limited by its cost and off-flavour generated in food products. Thus, this study optimized skim milk and yeast extract concentration as a cultivation medium for optimal Lactobacillus acidophilus ATCC 4356 biomasses using FCCD-RSM. The statistical analysis showed that the optimal compositions of skim milk and yeast extract were at 9.46 g/L and 1.07 g/L, respectively by setting the goal of optimization for biomass production to be at maximum level and the factor concentration in selected range. Besides, pH profiling showed pH value declined from 4.262 to 4.061 during cultivation due to organic acid produced from carbohydrate metabolism at the predicted response in optimal conditions (0.979 OD600) generated by the RSM tool. However, the experimental and predicted results were not significant difference (P>0.05) with low error percentage. As conclusion, the optimized skim milk (10g/L) and yeast extract (1g/L) obtained from RSM model and experimental values can be used to support better biomass production for L. acidophilus and prepare the cells for further application.
使用商业培养基来支持益生菌的生长受到其成本和食品中产生的异味的限制。因此,本研究利用FCCD-RSM优化了脱脂乳和酵母提取物的浓度,作为培养嗜酸乳杆菌ATCC 4356生物量的培养基。统计分析表明,以生物质产量达到最高水平为优化目标,且因子浓度在选定范围内,脱脂乳和酵母浸膏的最优配比分别为9.46 g/L和1.07 g/L。此外,pH谱分析显示,由于碳水化合物代谢产生的有机酸,在RSM工具生成的最佳预测条件下(0.979 OD600), pH值从4.262下降到4.061。但实验结果与预测结果差异无统计学意义(P>0.05),错误率低。综上所述,优化后的脱脂乳(10g/L)和酵母浸膏(1g/L)可用于支持嗜酸乳杆菌更好的生物量生产,并为进一步应用做准备。

Coagulation process using low dosage of plant-based coagulant to remove high chemical oxygen demand (COD) and turbidity is important for water treatment. This study presents the treatment of pond water using plant-based pineapple leaf coagulant to achieve high COD and turbidity removal. The coagulation was performed using a jar test experiment of pond water at different pH followed by different dosages of pineapple leaf coagulant. It was found that the highest COD and turbidity removal ranged between 94.1 – 94.6 % and 88.3 – 88.4 % at pH 8 respectively, using low dosage (50 mg L-1) of pineapple leaf coagulant. The final COD and turbidity values ranged between 7.3 – 8.0 mg L-1 and 17.7 – 17.8 formazin turbidity unit (FTU) respectively, which are lower compared with results from other studies that used high dosage coagulants. Moreover, the final pH, COD, turbidity, dissolved oxygen (DO), and total suspended solid (TSS) values of the treated pond water were below the standard limits set by the National Water Quality Standards for Malaysia (NWQSM) class IIB, which represents water bodies suitable for recreational use with body contact (DOE, 2016). Therefore, it is expected that the newly-formulated waste utilisation of pineapple leaf coagulant can reduce the usage of chemical coagulants and can further be used for different types of water.

Morinda citrifolia or Noni is known as an important dietary supplement, food functional ingredient, or as natural health enhancer that is used throughout the world. Different parts of the plant have been proven to carry compounds that have high medicinal values such as terpenoids, alkaloids and anthraquinones. The stem bark of Morinda citrifolia collected from different types of soil were studied. It aimed to investigate the influence of different geographical factor on its metabolite profile by multivariate statistical analyses of spectral data deduced by NMR methods. A metabolomic approach employing concatenated GCMS and NMR data was utilized to study the relationships between environment and plant metabolism. Morinda citrifolia stem barks were pulverized into fine powder. They were extracted using chloroform and were taken to dryness in a rotary evaporator under reduced pressure. The Morinda citrifolia crudes were proceeded for Nuclear Magnetic Resonance (NMR) analysis. Visual inspection on the 1H-NMR Morinda citrifolia spectra showed that the different geographical areas have similar profile, but they have different concentration of various constituents. Major constituents identified were aromatics (δH 7.25-7.50), sugars and glycosides (δH 2.25-5.0), fatty acids/aliphatics (δH 0.5-2.0) and aldehydic compound (δH 9.75). However, since the difference among the geographical areas were not clear from visual analysis, the analysis was proceeded using multivariate analysis, Principal Component Analysis (PCA) model. Thus, further analysis was done to examine the consistency of geographical area for each batch of Morinda citrifolia. This is to identify which type of soil is suitable as class model.
Morinda citrifolia或Noni被认为是一种重要的膳食补充剂,食品功能成分,或作为天然健康增强剂在世界各地使用。该植物的不同部分已被证明含有具有高药用价值的化合物,如萜类化合物、生物碱和蒽醌。对不同土壤类型采集的桑葚茎皮进行了研究。通过对核磁共振光谱数据的多元统计分析,探讨不同地理因素对其代谢谱的影响。利用串联GCMS和NMR数据的代谢组学方法研究了环境与植物代谢之间的关系。将桑叶茎皮粉碎成细粉。它们是用氯仿提取的,并在减压的旋转蒸发器中干燥。采用核磁共振(NMR)方法对桑葚胚进行分析。对桑叶的1H-NMR光谱进行目测,发现不同地理区域的桑叶具有相似的剖面,但各成分的浓度不同。主要成分为芳香化合物(δH 7.25 ~ 7.50)、糖和糖苷(δH 2.25 ~ 5.0)、脂肪酸/脂肪化合物(δH 0.5 ~ 2.0)和醛类化合物(δH 9.75)。然而,由于地理区域之间的差异从视觉上看并不明显,因此使用多变量分析,即主成分分析(PCA)模型进行分析。因此,进一步的分析,以检查地理区域的一致性,为每批桑叶。这是为了确定哪种类型的土壤适合作为类模型。

The purpose of the article is to assess the current challenges in the implementation of the Digital Culture Environment among the rural community in Malaysia. The Covid-19 pandemic has changed the online environment where a drastic usage of digital tools has been observed among Malaysian. The digital culture is defined as the culture shaped by the emergence of digital technologies and their usage in the community. The literature survey approach has been applied as the methodology of study to explore the current challenges in the implementation of the Digital Culture Environment among the rural community in Malaysia. Several challenges have been identified, including the rural sustainable issues, digital divides, demographic factors, Information, Communication and Technology (ICT) factor, individual, as well as behavior factor. According to the literature review conducted, these challenges have been revealed to significantly hurdle the government’s movement in implementing the digital culture within the rural community. To overcome these challenges, a strong and effective supporting model should be formulated to assist the government in building and establish a digital culture environment in Malaysia, particularly among the rural community. Hence, a further in-depth study is required to acquire comprehensive literature information to address this issue.
这篇文章的目的是评估目前在马来西亚农村社区中实施数字文化环境的挑战。新冠肺炎疫情改变了网络环境,马来西亚人大量使用数字工具。数字文化被定义为由数字技术的出现及其在社区中的使用所塑造的文化。文献调查方法已被应用为研究方法,以探讨目前在马来西亚农村社区中实施数字文化环境的挑战。已经确定了若干挑战,包括农村可持续问题、数字鸿沟、人口因素、信息、通信和技术(ICT)因素、个人和行为因素。根据所进行的文献综述,这些挑战已被揭示为显著阻碍政府在农村社区内实施数字文化的运动。为了克服这些挑战,必须制定一个强大而有效的支持模式,以协助政府在马来西亚,特别是在农村社区建立和建立数字文化环境。因此,需要进一步深入研究,获得全面的文献资料来解决这一问题。
