A review on the influence of drinking water quality towards human health

An adequate supply of safe drinking water is one of the major prerequisites for a healthy life. Inadequate of safe drinking water produce waterborne disease and a major cause of death in many parts of the world, particularly in children. Therefore, it must be treated properly before it can be used and consumed. This chapter provides the guidelines of important parameters for drinking water standard in order to ensure the safeness of drinking water. All the selected parameters were elaborated on the effect of high concentration if human consume the drinking water directly

The Usage of Home Water Filtration System in Malaysia

Installation of a water filter system for household use has become a necessity for Malaysians to get safe drinking water quality. Various types of machinery products of water filters have entered the Malaysian market with certain quality assurance. In the present, there were no guidelines for the water filter system in Malaysia that can prove water quality assurance given by the provider. The aim in this study is to produce a good reference based on the factor affecting the user choosing a water filter system. The method that was used is the collection of data from the questionnaire and survey of feedback from consumers. This result can determine the pattern and selection factor of a water filter machine product. The major factor in the selection of water purifier machines is the price offered and the main information about the product is obtained through the advice of friends and neighbours. The second aim of this study was conducted to determine the quality of the water filter before and after through a water filter system. The results of water quality tests before and after through water filter system showed three forms of concentration changes in chemical water quality parameters were tested. First forms of concentration, there was a high percentage removal rate that exceeds 75% in all types of water filter brands. Second, the result of the water quality test for tap water and after filtering water sample shows no significant difference for the concentration parameters before and after passing through a water filter system. Third, there was an increased in the concentration of water after through water filter system. The results of chemical water quality test for three brands which have twelve parameters was given good performance on Brand A (Model 1). However, the water quality before and after passing through a water filter system still meets drinking water standards of the Ministry of Health. The results of this study can be used as a reference source for Safety Division and Food Quality, Ministry of Health Malaysia in developing water filter system guidelines for household use

Physicochemical properties of rambutan seed fat / Nadya Hajar [et al.]

Rambutan (Nephelium lappaceum L.) fruit is abundantly present in Malaysia. It is a seasonal fruit that present twice a year. It has short shelf life at ambient temperature has contributed to fruit wastage. Thus, the initiative of producing canned rambutan is an innovation that makes rambutan fruit available throughout the year. The canned rambutan industry leaves large amount of rambutan seed. This study focused on utililization of rambutan seed as valuable product which is Rambutan Seed Fat (RSF). The RSF was extracted using Soxhlet Extraction method for 8 hours. The objective of this study was to determine the physicochemical properties of RSF: melting point (°C), Refractive Index (RI), Total Carotene Content (TCC), water activity (Aw), acid value (AV), peroxide value (PV) and saponification value (SV). The results showed that: 38.00±1.00 – 48.83±1.61°C melting point, 1.46±0.00 RI, 1.18±0.06 mg/kg TCC, 0.4721±0.0176 Aw, 1.2162±0.1520 mg KOH/g AV, 9.6000±0.4000 g/g PV and 146.8040±18.0182 mg KOH/g SV, respectively. According to the results, RSF showed high industrial potential as cocoa butter replacement in chocolates and cosmetics production as the physicochemical properties of RSF is quite similar to cocoa butter

Scienceploration 2023

The Scienceploration Camp is an initiative of the Centre for Pre-University Studies, UNIMAS (PPPU), which aims to increase the interest in science among secondary school students. It is also an effort taken by PPPU towards the achievement of Sustainable Development Goals 4 in providing equal quality education and promoting lifelong learning opportunities for all. On top of that, this camp supports Sarawak’s Digital Economy Strategy in nurturing an integrated ecosystem to foster inclusive digital society, by building the right foundations to grow our local digital economy
