The largest source of energy currently utilized is still predominantly from fossils. Fossil energy sources are non-renewable so over time they will run out. So it is necessary to utilize renewable energy sources. One renewable energy source that is environmentally friendly and easy to obtain is wind energy. Wind is a collection of air that is experiencing movement due to a difference in pressure on the earth's surface. Wind will move from areas of high pressure to areas of lower pressure. Experimental research on wind energy is a useful energy that can be put to good use. Wind energy is a form of energy that comes from utilizing air flow in the atmosphere to produce mechanical or electrical energy. The main technology used to utilize wind energy is a wind turbine, which converts wind kinetic energy into electrical energy through a generator. Which of course also requires sufficient wind speed so that the wind turbine can rotate and produce mechanical movement in the form of rotational torque which can then be converted into electrical energy. Wind energy has great potential as a clean, sustainable and environmentally friendly resource, as it does not produce greenhouse gas emissions or hazardous waste during its operation. However, wind energy development faces challenges such as fluctuations in wind speed, large land requirements, visual impacts, and potential disruption to local ecosystems. With technological innovation and careful planning, wind energy can be a significant solution to meet global energy needs in a sustainable manner.

The rapid advancement of technology has led to an increasing demand for electrical energy. One of the efforts to meet this demand is the development of micro-capacity power generation systems utilizing heat energy. Heat energy can be harnessed using thermoelectric elements. This study aims to design and develop a portable power generation system that utilizes solar heat as an energy source. The prototype uses six TEC 1-12706 thermoelectric modules to generate electricity designed specifically to recharge devices such as phones, power banks, and flashlights. Solar heat is concentrated on the thermoelectric modules using Fresnel lenses, while heatsinks are employed for cooling. The thermoelectric modules are connected in series to produce sufficient voltage, which is then boosted by a boost converter. The generated electrical energy is stored in a battery to ensure voltage stability despite temperature fluctuations. This device can also operate at night due to the energy stored in the battery. Test results show that the average output voltage without load ranges from 9.49V to 9.56V, with an average temperature of 45.2°C at the thermoelectric modules. In load tests, the device successfully charged a Pixel 5 phone (5000 mAh battery) from 4% to 70% in 95 minutes. These results demonstrate the potential of this system as a reliable and environmentally friendly portable energy solution.

Porous asphalt is an open graded hot mix asphalt with a small percentage of fine aggregate and a large percentage of coarse aggregate. Porous asphalt is an asphalt mixture that is being developed for wearing course construction. The aim of this research is to analyze the effect of adding rubber tire powder on the performance of the Asphalt Porous-Wearing Course. In this research two standard gradations for porous asphalt were used, namely Australian gradation (AAPA) and California gradation (CalTrans) with the addition 0%, 2%, 4%, and 6% of rubber tire powder. Based on the research carried out, it can be seen that the addition of rubber tire powder to a mixture with AAPA gradation is better in terms of its ability to accept loads without experiencing deformation (stability) and the possibility of the mixture being able to withstand maximum loads to prevent traction failure (ITS). Meanwhile, mixtures with Caltrans gradations are better in terms of resistance to wear (CL), homogeneous mixing of asphalt and aggregate (AFD), and ability to resist cracking (TSR). The addition of rubber tire powder was not able to improve the strength due to immersion at extreme temperatures (IRS) in a mixture of both gradation specifications.
