Published: September 2023

In the world of construction, concrete still plays an important role as the main material used. This is because concrete has several advantages such as ease of work, the use of solid waste as material substitution in the industry is not new. However, the use of solid waste as a substitute for aggregates in concrete has been increasing in recent years, as a promising solution to reduce inorganic solid waste. From the tests carried out in the university tribhuwana to laboratories, it shows that for compressive strength and tensile strength, it decreases. The concrete compressive strength test results with added material in the form of tire chips and in the testing of compressive strength for 5% used tire waste burned 13.22 MPa, as well as 10%, the value burned 9.74 MPa, and for compressive strength test 15% of the value decreases for compressive strength with a mixture of burnt tire chips 4.77Mpa. The graph of the concrete tensile strength test with added material is in the form of tire chips and in testing the tensile strength for used tire waste 5% with for concrete that is not burned 1.844Mpa value. Likewise with 10% for unburned concrete the value of 2,020Mpa with a mixture of used tire waste as added material. And for the tensile strength test 15% the value decreases for non-burned concrete with a quality of 1.544Mpa.

Indonesia as a developing country that is moving into a developed country, has a very large development point of the country. Development has begun to be leveled in many regions, of course, with rapid development, materials that support productivity, quality and efficiency are needed so that they can be utilized properly by the construction world. One that has been widely developed and used is the use of light bricks, with the light bricks the productivity of a construction work is much higher. The process of making light bricks is divided into 2, namely AAC and CLC, the process of making AAC light bricks is generally made by large companies because the manufacturing equipment is quite expensive, while for middle to lower industries generally use the CLC or Celullar Lightweight Concrete system, with a relatively simple process so that easy to apply. There have been many studies that have been developed to produce good CLC lightweight bricks, one of which is by making fine aggregate better, one of which is trying to substitute fine aggregate with Tuban silica sand with a substitution ratio of 0%, 25%, 50%, 75 %, and 100%, The results showed that the substitution with the most optimal mixture was at 75% substitution. This is because at 75% substitution, the compressive strength of lightweight CLC bricks has the greatest value but with a relatively low volume weight compared to other substitutions. In addition, the compressive strength with 75% substitution is in the highest quality III in SNI compared to the other mixtures.

The energy source for electricity generation in Indonesia is mostly supplied from fossil energy, but this energy source will run out in the next 20 years. Various researches are now leading to the development of alternative energy sources such as solar energy. There are two kinds of solar energy utilization technologies, namely solar thermal energy technology and solar photovoltaic energy. Thermal solar energy in Indonesia is generally used for the drying process of agricultural and marine products, while photovoltaic solar energy is used to meet electricity needs, especially in remote areas. Most solar panels are installed permanently at a fixed angle. This causes the solar panels to be unable to absorb solar heat optimally because the sun is always moving. Therefore we need a tool that can move solar panels to follow the direction of the sunlight. The tool used is known as a solar tracker panel. This tool consists of an Arduino Uno as a microcontroller, an LDR (light dependent resistor) as a sensor and a servo motor to drive the solar panels. This tool is double axis, so it can (up and down) as well (to the left and right). The purpose of making this tool is to optimize the absorption of sunlight into the solar panels in order to further reduce the cost of spending electricity PLN. This type of research used in this research is quantitative research with a descriptive approach. The test results proved to be more efficient than the patented on-site solar panels. This tool is applied as a source of energy for water pumps and also for other items such as lamps,.etc
