The physicochemical and antioxidant properties of double-boiled kelulut honey

Kelulut honey is a unique Malaysian food that has beneficial components and high potential in many health aspects. In commercial processing plant, honey is usually subjected to thermal treatment, where its quality is compromised due to unstable and thermolabile components. Therefore, double boiling was chosen as it does not exert significant heat, thus minimizes damage done. The quality was determined after treated by double boiling technique at optimized condition. Three different sources of Kelulut honey based on the main types of foods consumed by the bees (Coconut, Multifloral and Wild Flowers) were tested. Kelulut honey samples were subjected to an optimized condition at 60 °C for 35 minutes. Thermal treatment at the same condition was conducted for comparison purpose. The results showed that double boiling treatment increased the total phenolic content of Kelulut-C honey significantly, from 2430.78 ± 12.24 to 2711.10 ± 23.00 mg GAE/100 g. The treatment also significantly increased the brown pigment for both Kelulut-C and Kelulut-W honey by 11.11 ± 0.00% and 27.27 ± 0.00%, respectively. Whereas, the pH and moisture content of all samples remain unchanged with no formation of hydroxymethylfurfural (HMF) was observed. A preliminary four-week storage study showed that double boiling treatment improves physicochemical properties of Kelulut honey as compared to the untreated samples for all three types of Kelulut honey tested. Meanwhile, a room temperature (27 °C) condition leads to an improvement of antioxidant properties as compared to cold temperature (4 °C). In conclusion, double boiling treatment has established itself as a good alternative processing method for Kelulut honey, hence increasing the possibility to bring forward Kelulut honey as a unique source for the application in food and beverages industries

On the Basis Property of the Root Functions of Some Class of Non-self-adjoint Sturm--Liouville Operators

We obtain the asymptotic formulas for the eigenvalues and eigenfunctions of the Sturm-Liouville operators with some regular boundary conditions. Using these formulas, we find sufficient conditions on the potential q such that the root functions of these operators do not form a Riesz basis

The Utilization of Waste Shallot Skin (Allium Cepa L) as Natural Dyeing Material for Textile Product

Previous studies on the onion skin as a natural dye by Made Diah Angendari showing the colour of each mordant used a Jumputan and suggested using a different concentration of mordant in the next research. Based on it, interviews were conducted to three different speakers: KLP Nusantara, Mrs Kuswati, and Dapur Alifa. According to the interviewers, all can produce ±64 kg of onion skin per month and most of the onion skin were thrown or burned. Based on it, a research was done by using a variation of colouring matter, mordant measurement, dyeing technique, dyeing duration, and technique of textile to use plenty onion skin and develop technique on the natural dye of onion skin. To obtain the required data, the student collects the data with experimental methods, such as by observation, interview, literature study, and experimentation. The results of the elected experiment show that the used of iron post-mordanting and an hour cold dyeing technique have a good result based on the endurance of wear-off in Balai Besar Tekstil Bandung and it was applied to a textile product in the form of long cloth with different measurement.

Molecular characteristic of phosphoric acid treated soils

The expansive nature of soils containing high amounts of clay minerals can be altered through chemical stabilization, resulting in a material suitable for construction purposes. The primary objective of this investigation was to study the changes induced in the molecular structure of phosphoric acid stabilized bentonite and lateritic soil using Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FTIR) spectroscopy. Based on the obtained data, it was found that a surface alteration mechanism was the main reason responsible for the improvement of treated soils. Furthermore, the results indicated that the Al present in the octahedral layer of clay minerals were more amenable to chemical attacks and also partly responsible for the formation of new products

Self-machinery?: steel trusses and the management of ruptures in eighteenth-century Europe

Abstract: Effectiveness Of Rice Husk Ash And Poly Aluminum Chloride In Reducing Exposure Colour Liquid Waste Industry Sasirangan. Sasirangan fabric industry is the textile of industry in Kalimantan Selatan produce wastewater of dyeing cloth sasirangan process that uses water as a primary adjuvant in stage process.The study aims to determine the effectiveness of rice husk ash and Poly Aluminium Chloridereduce levels of dyes in wastewater sasirangan "Oriens Handycraft". This study tested a laboratory scale with dose variation of rice husk ash and Poly Aluminium Chloride for reduced levels of dyes in wastewater sasirangan. The study design is a randomized pretest - posttest control group design. The population of the waste liquid fabric manufacturesasirangan results and samples are the waste from the manufacture of cloth sasirangan which represents the population. This study conduct statistical tests usingKruskal Wallis and Mann-Whitney Test.Theresultsofthestudyof color levels priorto treatment equal to 2,712 PtCo and after treatment ranges from 676.3 to 978.7 PtCo at a dose of 58 grams of rice husk ash; 59 g; 60 g; 61 g; 62 gr and Poly Aluminium Chloride 0.5 gr. For a dose of 58 grams of rice husk ash; 59 g; 60 g; 61 g; 62 gr and Poly Aluminium Chloride 1 g of color levels before treatment and after PtCo 1775 amounted to 227.7 PtCo ranges up to 240 PtCo. Rice husk ash and Poly Aluminium Chloride effective at pH 6.5 - 7. Results of normality test showed abnormal data. Kruskal Wallis test probability value 0.002 <0.05, there is a difference between the average dosing in the control group and the treatment group and the Mann-Whitney Test probability value of 0.009 (0.018 <0.05), the rice husk ash dosing and Poly Aluminium Chloride 1 g more effective than rice husk ash dosing and Poly Aluminium Chloride 0.5 g.Efforts government can do is provide the appropriate policy on effluent quality standards and attention to industrial waste disposal sasirangan. For the industry can manage its waste before waste into the environment. Keywords: SasiranganWaste; Materials coagulant; pH; Dye

Forecasting wind speed data by using a combination of ARIMA model with single exponential smoothing

Wind serves as natural resources as the solution to minimize global warming and has been commonly used to produce electricity. Because of their uncontrollable wind characteristics, wind speed forecasting is considered one of the best challenges in developing power generation. The Autoregressive Integrated Moving Average (ARIMA), Simple Exponential Smoothing (SES) and a hybrid model combination of ARIMA and SES will be used in this study to predict the wind speed. The mean absolute percentage error (MAPE) and the root mean square error (RMSE) are used as measurement of efficiency. The hybrid model provides a positive outcome for predicting wind speed compare to the single model of ARIMA and SES

Data analytics for modeling and visualizing attack behaviors: A case study on SSH brute force attacks

In this research, we explore a data analytics based approach for modeling and visualizing attack behaviors. To this end, we employ Self-Organizing Map and Association Rule Mining algorithms to analyze and interpret the behaviors of SSH brute force attacks and SSH normal traffic as a case study. The experimental results based on four different data sets show that the patterns extracted and interpreted from the SSH brute force attack data sets are similar to each other but significantly different from those extracted from the SSH normal traffic data sets. The analysis of the attack traffic provides insight into behavior modeling for brute force SSH attacks. Furthermore, this sheds light into how data analytics could help in modeling and visualizing attack behaviors in general in terms of data acquisition and feature extraction
