In the future, the need for energy will increase because every year there is a large population growth. If you still use fossil energy and don’t find new energy alternatives, then Indonesia will experience a severe energy crisis and certain places will experience blackouts. One of the efforts so that the wind energy crisis can be minimized is to utilize natural energy that has the potensial to generate energy such as the Wind Power Plant. In this study, planning and simulation of Wind Power Plant were carried out to help reduce the use of fossil energy and help the needs of the community in the Talise Beach area. From the results of the study that the average output of wind turbine production is 1,180/hour winh a maximum production of wind turbines per day of 5,665 kW and the construction system cost (NPC) of Rp. 91,340,660,000. Electrical energy that can be generated from wind turbines by utilizing an area of about 42,021.6...

In this study, ATS was designed based on the Arduino Nano microcontroller as an automatic control that works based on voltage readings. Using the Arduino Nano microcontroller can facilitate the process of making tools and minimize the use of components. This ATS uses the PZEM-004T voltage sensor module. The voltage sensor module functions to detect and measure the value of the PLN voltage. From the test results, it was found that the time lag between the PLN supply being cut off until the battery was supplying and ready to be loaded was an average of 2.79 seconds. Meanwhile, the time lag when the PLN supply turns on again until the battery supply is cut off and the load supply is again served by PLN is 3.07 seconds on average. Other tests found that in measuring battery resistance with a load of 20 watts, the current obtained is 1.66 amperes with a usage resistance of 27 hours, while when the load is 200 watts the current is 16.66 amperes while the resistance to use is 2.7 hours. The length of battery life is affected by the magnitude of the load.

One alternative energy source that is suitable for the equatorial region is solar energy. One of the technologies for utilizing solar energy that has begun to be widely used in Indonesia is the photovoltaic (PV) system. The output of PV is highly dependent on environmental conditions, especially the intensity of the sun and temperature. In addition to these two factors, shading (shadows) and soiling (dust) also affects the PV output. So, this must be observed at all times by monitoring the voltage and current as the PV output. This study aims to design a PV panel instrumentation structure based on a data logger. PV output data in the form of voltage and current and environmental conditions such as ambient temperature and solar intensity were recorded in real-time. The measurement results from the data logger will be compared with manual measurements. P...

To find out whether it is feasible or not, a method is needed to detect a water quality system that is easy to apply at an economical price so that people can know for sure the quality of the water they use for their daily needs. Therefore, a tool is designed to determine the quality of water, which samples are taken around the coast of Tondo by using the Fuzzy Logic method. This design was built using the Arduino module by combining four sensors, namely a pH sensor, a TDS sensor, a Turbidity sensor, and a temperature sensor. Water quality in this study was divided into three groups, namely drinking water (UM), water for washing (UC), and water not suitable for use (TL). While the water quality benchmarks are known from the incorporation of existing sensor readings, so that the value of water quality measured in the study is in the unsuitable category with a fuzzy value of 100 ...

PVT combine photovoltaic modules and solar thermal collectors, forming a single device that receive solar radiation and produces heat and electricity simultaneously. The collector figures out serpentine-parallel tubes that can prolong fluid heat conductivity from morning till afternoon. During testing, cell PV, inlet and outlet fluid temperaturs were recorded by thermocouple digital LM35 Arduino Mega 2560. Panel voltage and electric current were also noted in which they were connected to computer and presented each second data recorded. But, in this performance only shows in the certain significant time data. This because the electric current was only noted by multimeter device not the digital one. Based on these testing data, average cell efficieny was about 19%, while thermal efficiency of above 50% and correspondeng cell efficiency of 11%, respectively.

However, low carbon steel use is highly suceptible to corrosion. T he corrosion of motorcycle components (fuel tank) can decrease strength, tank life, that will harm the safety of motorists. In addition, corrosion in fuel shelters (premium and pertalite) can result in leakage of the container . The leakage is very vulnerable to fire. This research aims to analize corrosion rate of low carbon steel speciments that immerse in fuels, premium and pertalite. Method of research includes preparation, cutting and weighing of specimens before immersing the specimen in the fuel.

However, the voltage of photovoltaic (PV), one of solar technology, drops as the temperature rises. Therefore, efforts are required to lower the temperature in the photovoltaic. This study aimed to observe the effect of cooling PV on direct-coupled water pump, motor and pump connected directly to PV. In this study, the cooling method used is floating method. Two module of PV were used. A photovoltaic module is firmly installed on an artificial pool as a cooling PV and the other without cooling. The results showed that a cooling photovoltaic (PV) produced higher power output transferred to motor and pump and had higher efficiency. In general, the power generated during the period measurement by PV with cooling is greater than that of PV without a cooling method. At 17:00 pm, when the intensity reaches 236 W/m...

Dari hasil beberapa penelitian sebelumnya menunjukkan bahwa panel monocrystalline menyerap panas yang besar dibandingkan dengan yang jenis polycrystalline pada kondisi cuaca yang sama. Jika ini terjadi dalam jangka waktu yang lama, maka suhu permukaan panel akan semakin tinggi yang berimplikasi menurunnya efisiensi elektrik dan/atau konversi energi panas menjadi energi listrik akan berkurang. Oleh karena itu dibutuhkan media pendingin yang saling menguntungkan. Artinya dengan menhybrid dengan sirkulasi fluida (T) pada photovoltaic (PV) atau PVT, akan mempertahankan bahkan meningkatkan efisiensi elektrik PVT meskipun efisiensi thermal pada artikel ini masih perlu ditingkatkan. Disamping itu, arus yang dihasilkan lebih besar jika dengan PVT dibandingkan PV, sementara tegangan listrik cenderung tetap. Efisiensi elektrik maksimum PVT yang dihasilkan a...

The weight loss of steel was identified by immersion test. The coconut water used was young and old coconut water. The concentration of coconut water, whether young and old, in 3.5% NaCl was varied. The results showed that the corrosion rate of steel decreased with increasing coconut water concentration. Furthermore, old coconut water can further reduce the rate of corrosion in mild steel comparing young coconut water.
