Hasil dari kegiatan ini didapatkan bahwa anak PAUD Mandiri Desa Suka Negeri terlihat sangat bahagia dan penuh semangat saat dilaksanakan kegiatan ini, dan menarik perhatian sehingga bisa menumbuhkan motivasi anak-anak untuk belajar, setelah kegiatan tersebut  anak- anak PAUD lebih aktif

Rapid detection of ethanol in beverages using IIUM-fabricated electronic nose

This study has been successfully conducted to develop a method for rapid detection of ethanol (EtOH) concentration in beverages using portable electronic nose (E-Nose) developed by International Islamic University Malaysia (IIUM). E-Nose is widely used in food analysis. However, E-Noses used in food industry are big and not portable. The very recently-developed portable device used in this study is very handy and practical for use. Results from this study revealed that the device could be used for rapid detection of ethanol concentration in various beverages such as alcoholic beverages, isotonic drinks, soft drinks and fruit juices from different brands sold in Malaysia. From the result obtained, it was shown that the device has high accuracy and reliability where it could detect ethanol concentration as low as 0.1% (v/v). The analytical condition for the detection was achieved with the lowest voltage output of 0.43V. While for optimization analysis using Response Surface Methodology (RSM), optimum Headspace Generated Time (HGT) and bottle’s volume (mL) obtained are 0.66h and 100mL, respectively

The development of rapid method for detection of ethanol in mouthwash using E-Nose

The purpose of this study is to check for ethanol (EtOH) content in mouthwash products sold in Malaysia market using portable electronic-nose (E-Nose). For this study, 20 mouthwashes were tested with nine of the samples contain EtOH as part of its ingredients. The problem with those products is that it does not disclose the concentration of the EtOH as part of its labelling. This is important since long-term use of ethanol-containing mouthwash may result in adverse health effect to the consumer. The process parameters used in this study was optimized using Response Surface Methodology (RSM), with strong relations between actual and predicted sensor response yield correlation of determination, R2 of 0.9756. Optimum process parameters generated by Design Expert 7.1.5 showed that the optimum volume for EtOH sample was 5.84 mL for 1.45 min time of detection. While for screening process, it was found that from the detection of alcohol-free mouthwash using portable E-Nose, no alcohol content detected with ‘alcohol free’ was displayed on the LCD screen of the device. However, 9 out of 10 mouthwash samples that have no ‘alcohol free’ label on the products contain more than 10% (v/v) EtOH. Hence, this study had successfully optimized the process parameters and screened the mouthwashes sold in Malaysia market for the presence of EtOH

TEOREMA PALEY-WIENER-SCHWARTZ PADA DOMAIN NON KONVEKS

Paley-Wiener theorem is a theorem related to the Fourier transforms of analytic functions having continuous partial derivatives up to infinite times. The theorem has been generalized to be Paley-Wiener-Schwartzs theorem by characterizing Schwartz test functions and distributions with compact support. Usually Paley-Wiener-Schwartz theorem works on the domain that is compact and convex. In this thesis we discuss the theorem of Paley-Wiener- Schwartz on compact sets. Further we discuss Paley-Wiener-Schwartz theorem generated by the sequences of numbers and polynomials which can be nonconvex. Also we discuss the theorem of Paley-Wiener-Schwartz generated by the set of convex-d

Optimization of lard compound analysis using portable electronic nose based upon response surface methodology

Portable Electronic Nose (E-Nose) is a device that mimics human olfactory system and can be carried around for an “on-line” detection of lard in food. The objectives of this study wass to optimize process parameters for the determination of lard detection quantitatively. This study was important to increase the performance of the device in an efficient manner. The optimum conditions for the detection of lard were determined using Historical Data Design in Response Surface Methodology (RSM). This design was used to investigate the effects of the analytical conditions, namely weight (g), temperature (°C) and time (min). These parameters were found to give a positive effect on the sensor response, which plays an important role in the increment of the sensor response. While Analysis of Variance (ANOVA) shows that the selected quadratic model was significant with Fisher value of 40.77, as it adequately represented the data obtained. Moreover, regression analysis showed that 96% of the total variation was successfully explained by the models. Optimum process parameters generated by Design Expert 7.1.5 shown that 0.2g of lard is the minimum weight can be detected at 50°C for 3 minutes. Hence, this study had successfully optimized the process parameters using RSM for the presence of lard adulteration in food. © 2018, Malaysian Consumer and Family Economics Association.
