The sun is a source of energy that cannot be used up. Therefore, the utilization of solar energy must be a priority. With the many types of solar panels that have been developed, researchers conducted an analysis of 150 watt monocrystalline solar panels. The purpose of this study is to know the amount of current and voltage produced by solar panels in some conditions of the sky, namely cloudy, bright cloudy, and bright. The research method used was the experiment. From the data that has been obtained, it can be found that the energy produced by solar panels during cloudy ranges from 0.6-0.8 amperes, when it is cloudy, 0.9-1.9 amperes, and when bright 2.0-3.2 amperes. The amount of electrical energy that can be produced is 8%. However, if the sunny state can produce twice that Suggestions for readers are if you want to take data to make sure the solar panels are completely exposed to the sun during data collection and in the open area. Much better if the angle is adjusted in the direction of sunlight.

The study observed the effect of variations in the electrical properties of dopants molarity polyaniline nanofiber. Polyaniline nanofiber in this study is synthesized by the interfacial polymerization method in Toluene Aniline 0.31 with the APS 4mmol dopant HCl solution with molarity between 0.6 M to 2.4 M. The synthesis results obtained were characterized by Scanning Electron Microscope. The electrical property is also observed on the polyaniline nanofiber. The results of this study indicate that the increase in molarity of dopants affect the incremental conductivity and diameter of fiber of the material.

The results of this study in the form of the maximum acquisition of light intensity received by the solar panel on the slope angle. Solar radiation intensity carried out a great effect on the power (Pout) of Photovoltaic cell output, wherein the morning solar radiation intensity is greater with the result that it produces greater power. Sunlight intensity in the afternoon and evening tends to decrease so that the power that is halted is smaller. The magnitude of slope angle carried great effect on the output power (Pout) of Photovoltaic cells, where the greatest power at an angle of 0ᵒ obtained namely maximum Pout 17.01 W and maximum Voltage Vm is 19.5 V. While the minimum power Pout is 12 W and minimum Voltage Vm 14 V which obtained at an angle of 60ᵒ. Greatest efficiency (η) of Photovoltaic cells at an angle of 0ᵒ obtained. This is caused by the Voltage and current output of Photovoltaic cells Vm and Im which tend to decrease when the value of the Photovoltaic cell angle is large. Therefore the efficiency of the Photovoltaic cell output will decrease along with the decrease in the Photovoltaic cell output power.Keywords: Photovoltaic, slope angle, power, efficiency.

Surface Plasmon Resonance (SPR) phenomenon of the oxidizing and reducing polypyrrole (PPy) have been observed using a modified Au/PPy Kretschmann configuration. The observation was carried out through simulation Winspall 3.02 software and compared with some experimental data refractive index (n), absorbance index (), and thickness (τ) reported in other literatures with spectroscopy ellipsometry. This simulation assumed that the SPR system use BK-7 halfcylinder prism (n= 1,515) and the laser beam was generated by HeNe (λ= 632,8 nm). The result showed that the optimum layer thickness of polypyrrole with neutral electrolyte solution in the reduction state is of about 20 nm. The polypyrrole with an acid solution in the oxidation state showed that the reflectivity curve is sharper and the width of the curve is smaller than the neutral electrolyte solution in the reduction state with the SPR angle of about 46,810 and the reflectivity value of about 0,217. Polypyrrole in a state of oxidation and reduction, related to the absorption, film thickness, and dielectric constant of materials, affected to the SPR angle shift and dip curve

ABSTRAK Perkembangan dunia industri otomotif saat ini semakin berkembang, khususnya industri sepeda motor. Suatu mesin dikatakan memiliki performa yang baik apabila mesin tersebut mampu menghasilkan daya yang besar dengan konsumsi bahan bakar yang efisien. Performa mesin sepeda motor pada dasarnya masih bisa ditingkatkan dengan melakukan beberapa perubahan baik dari komponen maupun kontruksi mesin itu sendiri. SMK Tunas Bangsa Bumi Ratu Nuban merupakan salah satu SMK yang berada di kabupaten Lampung Tengah Propinsi Lampung. Salah satu jurusan pada SMK Tunas Bangsa Bumi Ratu Nuban yaitu TSM (Teknik Sepeda Motor) yang merupakan jurusan yang mempelajari tentang sepeda motor. Untuk mengimbangi perkembangan teknologi otomotif yang semakin pesat banyak yang melakukan modifikasi mesin sepeda motor baik dari kalangan bengkel umum maupun siswa khususnya SMK untuk meningkatkan performa mesin sepeda motor mereka. Namun dalam melakukan modifikasi banyak diantara mereka yang belum mengetahui tentang dasar-dasar modifikasi mesin sepeda motor tersebut. Maka dari itu perlu dilakukan pelatihan tentang dasar modifikasi mesin sepeda motor supaya dalam melakukan modifikasi dapat menghasilkan performa mesin yang maksimal. Pelatihan dilakukan dengan memberikan materi dan penjelasan serta pelatihan yang diikuti oleh siswa kelas X, XI dan XII di SMK Tunas Bangsa Bumi Ratu Nuban Lampung Tengah. Dengan adanya pelatihan maka dapat meningkatkan pengetahuan siswa tentang cara memodifikasi mesin sepeda motor.Kata Kunci : Pelatihan, Modifikasi Motor, Siswa SMK ABSTRACTThe development of the automotive industry is currently booming, especially the motorcycle industry. An engine is said to perform well if it is capable of producing great power with efficient fuel consumption. Basically, the performance of a motorcycle engine can still be improved with some changes to the components and construction of the engine itself. Tunas Bangsa Bumi Ratu Nuban Vocational School is one of the vocational schools located in Central Lampung District, Lampung Province. One of the specializations of the Tunas Bangsa Bumi Ratu Nuban Professional School is the TSM (Motorcycle Engineering), which is a department that studies motorcycles. To keep pace with the ever-faster development of automotive technology, many have modified motorcycle engines, both in general workshops and students, especially SMKs, to improve the performance of their engines. However, when making modifications, many of them are unaware of the fundamentals of motorcycle engine modification. Therefore, it is necessary to carry out training on the basic modification of motorcycle engines so that the modifications can produce maximum engine performance. The training was carried out with the provision of materials and explanations, as well as the training attended by students from classes X, XI and XII of SMK Tunas Bangsa Bumi Ratu Nuban, Central Lampung. With training, students' knowledge of how to modify motorcycle engines can be increased.Keywords: Training, Motorcycle Modification, Vocational High School Students

DSSC (Dye Sensitized Solar Cell) uses dye as a sensitizer material which is used as an electron donor to TiO2 nanoparticles and uses an electrolyte as an electron transport medium. One of the dye extracts of purple spinach and moringa leaves used as a photosensitizer is chlorophyll extract or anthocyanin. The nature of chlorophyll which is able to absorb light is a function of the dye in DSSC. Making Moringa leaf and red spinach leaf dye after being blended, dried and ground into powder. Then the Moringa leaf powder was mixed with 70% ethanol with the ratio of Moringa leaves and ethanol, namely 1:2, 1:3, and 1:4. Meanwhile, red spinach leaf powder was mixed with ethanol solution in a ratio of 1:3. DSSC fabrication shows that the voltage, current, and power produced increases with the increasing amount of ethanol used, namely 1.879 mW, 1.573 mW, and 1.98 mW. Meanwhile, red spinach leaves mixed with ethanol in a ratio of 1:3 showed that the results were higher than Moringa leaves. So from the results of DSSC Solar Cell fabrication using Moringa leaves and red spinach leaves, it shows that there is light absorption from these materials and an increase in the conductive properties of Moringa and red spinach DSSCs.
