The economy of the whole world developed so quickly, encourage increased consumption of energy gradually. Energy consumption in the building sector has also increased with the demands of society in thermal comfort in the room. With the hot weather, the influence of the temperature in the room will rise. Some things that need to be reviewed in the manufacture of concrete in the place are the price is relatively low, easy to obtain, has high compressive strength, and has resistant to any environmental conditions. However, some problems still need to be resolved in the development of the Phase Change Material (PCM) composite that has a stable form. The proposed PCM has a thermal comfort temperature (16-26 ℃). The main purpose of this research was to investigate the influence of addition beeswax as a water-resistant mixture on the mechanical and thermal properties of concrete. In this research, the cement used was ordinary Portland Cement and replaced some of its Weight with paraffin wax in the mixture. The results of the research with the use of 10, 20 and 30% beeswax in a mixture of a concrete show that the increase in the content of Beeswax resulted in a decrease in the compressive strength of 22% and an increase in heat absorption by the concrete between without PCM with the Concrete-PCM is obtained by 10%.

This study aimed to investigate the efficiency of fish silage mixed in compounded diets on growth and survival rate of grouper (Epinephelus coioides). Grouper (2,34±0,24 cm, and 4,17±1,82 g) were divided into four groups and cultivated in 1x1x1,5 m floating net cages. Each group fed with compounded diets containing 0, 1, 3 and 5 g/kg fish silage diet twice daily. Fish were sampled for growth performances and feed efficiency at 14 days interval for 10 weeks. Results indicated that compounded diets at 1 and 3 g/kg silage affected the growth rate. Total length, specific growth rate and weight gain significantly increased in fish received 1 and 3 g/kg silage diets. The feed intake seen to be highest in groups administered 3 g/kg silage, whereas the best feed conversion ratio was found in fish fed 1 g/kg silage. Thus, this study indicated that using fish silage in compounded diets may affect feed efficiency and growth performances of grouper juveniles.Keywords:Artificial dietFeedingFish silageGrouperNet cages

Along with the development of technology, the need for fossil energy for cooking purposes using conventional stoves is increasing. The limitations of fossil energy reserves that cannot be renewed have resulted in an energy crisis starting to hit. Solar energy is an energy source that is environmentally friendly and available free of charge. Solar energy is utilized using the system. Concentrating solar power (CSP) focuses solar radiation to a point to get a higher temperature. This type of box-type solar cooker has a long history dating back to the 18th century when Nicholas-de-Saussure first made this type of solar cooker. A parabolic solar cooker is a solar-powered stove that uses reflections from the sun's radiation which is concentrated directly on the pan. A trough solar cooker collects sunlight and reflects it to a focal point using a reflective film. A box-type solar cooker has an important part between the reflectors which use aluminum foil with a diameter of 41 cm and a thickness of 0.2 mm. The collector was made of brass copper for cooking with a diameter of 41 cm and a thickness of 0.2 mm. The parabolic type of solar cooker has important parts, including a collector that uses a parabola with a diameter of 140 cm and a depth of 40 cm and a reflector that uses a reflective film with an emissivity value of 0.91. The trough-type solar cooker performs better than the box and parabola types because it has a higher temperature where the ambient temperature is 25.5 ℃, the focal point temperature is 164℃, and the load temperature is 163℃.
