Preliminary Investigation of Wastewater Phycoremediation and Biomass Productivity using Locally Isolated Green Microalgae from Ipoh, Malaysia

2024-08-16T06:36:02+00:00

This study investigated the potential of microalgae, sourced from a pond in Gunung Lang, Ipoh, Malaysia, for the phycoremediation of domestic wastewater. Under laboratory conditions, identified and confirmed microalgae species were introduced to wastewater samples to assess their capacity for removing Chemical Oxygen Demand (COD), nitrogen, phosphorus, and heavy metals such as chromium and zinc. The study also examined the relationship between algae growth rates and nutrient absorption, alongside a detailed analysis of wastewater to determine the extent of pollutant reduction. Initial analyses revealed that the COD levels of the domestic wastewater stood at 158 mg/l, failing to meet the Effluent Standard requirements as per the Malaysia Environmental Quality (Industrial Effluents) Regulations 2009. nitrogen levels were measured at 11.16 mg/l, phosphorus at 5.56 mg/l, chromium at 1.53 mg/l, and zinc at 0.53 mg/l under the heavy metal category. The study demonstrates that phycoremediation significantly reduces pollutants and nutrients in wastewater samples. Remarkably, zinc removal achieved a 100% success rate, while the lowest pollutant removal was observed for COD at the 10⁴ cell concentration in 100% wastewater concentration samples. The outcomes highlighted the efficacy of using microalgae for wastewater treatment, showing considerable promise in reducing environmental pollutants.

Navigating the Transition: Biodiesel Development and Challenges in Malaysia's Energy Landscape

2024-08-16T06:35:59+00:00

Overdependence on fossil fuels impacts the environment, economy, and society. The crude oil price increases when the supply of fossil fuels is insufficient, leading to economic recessions. The development of biodiesel has replaced fossil fuels in the transportation sector and is pending use in the industrial sector. It has brought various advantages to the economy, society, and environment. However, the development of biodiesel is still facing some challenges, such as labor shortages, the price of feedstock, environmental debates, and the adoption of biodiesel for the transportation sector. The introduction of the National Biofuel Policy and the Biofuel Industry Act 2007 has encouraged the use and development of biodiesel. Biodiesel technologies such as Envo Diesel, B5 biodiesel, B7 biodiesel, and B10 biodiesel were developed based on research done by the Malaysian Palm Oil Board (MPOB).

Exploring the Cultural Tourism of Malaysia: A Comprehensive Review

2024-09-29T23:52:43+00:00

In line with the Malaysia Tourism Transformation Strategy in 2020, the government devoted enormous resources to nurture and cultivate the industry to achieve the Tourism of National Key Economic Area (NKEA). This initiative aims at re-invigorating tourism within Malaysia. The unparalleled essence of foreign tourists depends upon culture and the attributes the experience evokes. Generally, tourism choices are more influenced by the cultural part and values of undisguised cultural virtues, whether in the form of tangible or intangible distinctions. Cultural elements direct tourism guidebooks, postcards, pictures, television programs, commercials, posters, and itineraries, etc. Cultural tourism projects can be viewed as a medium to highlight group distinctions. They also serve as tools in teaching, growth, performing economic and tourism roles. The vision and attribute of heritage and culture will signify destinations in the future. The Malaysian Tourism Blueprint (2010-2020) considers cultural tourism as one of the key pivot areas of another NKEA. This article intends to delineate the existing literature pertinent to cultural tourism in Malaysia. The review of the literature attempts to provide an extensive record of the current conceptual insights within the area. Given the immense potential of the country as a culturally rich destination, there is still room for exploring experiences and insights to keep the zeal alive for cultural products of Malaysia. At the top of this, the policy frameworks are geared towards enhancing tourism. As a culturally rich country, Malaysia needs to attract tourist interests to explore and visit Malaysia's roots, its people, and the diverse community that makes Malaysia unique. The findings of this literature review are instrumental in setting the future studies agenda in order to address the existing dearth of the knowledge base.
