Abstract

This article delves into the potential of the blue and green sectors situated in Langkawi Island, Malaysia. With its abundant marine and terrestrial resources, the island needs to strike a balance between its economic growth and environmental preservation imperatives. By leveraging the potential of green and blue sectors such as tourism, fisheries, renewable energy, agriculture, and forestry, Langkawi Island can serve as a model for responsible development, all while preserving its innate natural beauty and biodiversity. A survey was conducted involving 104 local respondents at various attraction points across Langkawi Island to assess the progress of these sectors. Overall, the respondents were predominantly in agreement regarding the impacts of development stemming from both the blue and green economies, coupled with the positive spill-over effects witnessed on the island. The descriptive findings indicate that the potential for growth within these blue and green economies is promising, buoyed by anticipation from both governmental and private sectors. As such, it becomes imperative for policymakers to formulate a comprehensive development plan that can adequately bolster the expansion of these sectors. This preparation will be crucial in ensuring the sustainable growth of Langkawi Island's blue and green economies, ultimately fostering a harmonious coexistence between economic progress and environmental conservation.

Abstract

Solar panels are an important utilization in generating renewable energy, but high temperatures can reduce energy conversion efficiency and shorten the lifetime of solar panels. This research aims to explore and evaluate the utilization of a combination of heatsink material and cooling water block as a solution to reduce the heat generated by solar panels. The research method includes the design and manufacture of a prototype consisting of solar panels mounted on a combination of heatsink material and water block. Experiments were conducted by varying the use of passive cooling and the absence of cooling on solar panels according to environmental conditions to evaluate the effectiveness of the system in reducing the temperature of solar panels. A power increase of 43.3% was achieved by comparing the system without cooling design with the passive cooling design system. The results showed that the use of a combination of heatsink material and cooling water block significantly reduced the solar panel temperature under various operational conditions. In addition, data analysis showed an increase in the energy conversion efficiency of the solar panel after the implementation of the cooling system. This research makes an important contribution to the development of more efficient and durable solar panel technology by addressing the problem of heat generation.
