Exploring acceptance on benefits of solar farm implementation in Malaysia. Implementation of solar farms to generate electricity is still low in Malaysia, where only 1%, or 227.5 MW of the total installed electrical capacity in Malaysia was produced from solar PV installations in 2016. Renewable energies, e.g. solar energy, have been adopted in many countries to generate electricity as a response to global environment issues. The aim of this study is to determine financial opportunities and benefits of solar farm implementation towards the society and the environment. Data were acquired through a literature review and questionnaire survey that was conducted among the respondents that are directly involved in the solar energy. Long-term financial savings constitute the most identified financial opportunities for the implementation of solar farms in generating clean electricity. Implementation of solar farms will encourage more businesses related to solar energy to be established in the country and will lead to new business opportunities. Solar farms are far better than conventional fossil fuel power plants in terms of the environmental effect and also reduce the health effects on the society during the electric generating process.

A study was conducted to explore the effect of palm oil boiler ash (POBA) on foamed concrete by varying the percentage of POBA over sand quantities (0, 4, 8 and 12%). This paper primarily discusses the water absorption test, uniaxial compressive strength, and dry density findings. It indicates that substituting sand with POBA greatly enhances the strength of foamed concrete. When the quantity of POBA was raised up to 12% throughout all curing times, the compressive strength steadily increased in the range of 4.34–13.50 N·mm–2. Furthermore, the dry density of foamed concrete was shown to be directly related to the fraction of POBA in the mixture. The dry density of foamed concrete increases as the amount of POBA increases. Despite this, water absorption shown that increasing POBA increases water absorption percentage in foamed concrete from 7.4 to 10.4%. This is due to the fact that a composition with a high POBA percentage will generate more pores than a mixture with a low POBA percentage.
