A preliminary study on the distribution of fruit tree taxa at Ayer Hitam Forest Reserve, Selangor
An assessment on the fruit trees families Burseraceae, Sapindaceae and Meliaceae showed that 714 trees from 10 genera representing 26 species were identified in the 5-ha plot. Sixteen mother trees were identified and all are Burseraceae explaining the high populations compared to Sapidaceae and Meliaceae. Despite the Ayer Hitam Forest Reserve being not fully recovered from the effects of previous logging activities, the diversity of fruit trees present is commendable in supplying food to different wildlife
Tree taxa inventory at Ayer Hitam Forest base-camp
An inventory at the base camp along 6 new trails recorded a total of 86 species of seed plant taxa in 68 genera
and 32 families. Of this number 22 timber species, 9 fruit tree species, 3 species with medicinal values and 8
species producing dye and tannins were identified. 6 Peninsular Malaysian endemics are also found here, two
being new records for Selangor. This area is useful for teaching and practical training for forestry related and
environmental courses
Solar photovoltaic water pumping system approach for electricity generation and irrigation: Review
Solar energy for water pumping is a possible alternative to conventional electricity and diesel based pumping systems, particularly given the current electricity shortage and the high cost of diesel. The literary survey includes a comparison between previous studies of the pumping system by photovoltaic cells and the extent of the influence of external factors such as radiation intensity and temperature on the efficiency of the system. As well as the use of water storage to generate electrical energy through potential energy by means of hydraulic generators and the effect of the amount of flow and height on the amount of energy generated, as well as the types of generators Hydraulics. Nowadays, solar power is a major contributor to the world's electrical energy supply by generating electrical energy directly from solar cells or through water storage, which we will address through this review. When compared to electricity or diesel powered systems, solar water pumping is more cost effective for irrigation and water supply in rural, urban, and remote areas. It also makes an effort to bring to light the challenges that must be overcome in order to develop high-quality, long-lasting solar power technology for future uses
