Analisis Konsumsi dan Fluktuasi Arus dan Daya pada Mikrokontroler Menggunakan Sensor INA219
Get PDFKonsumsi arus dan daya pada mikrokontroler menjadi salah satu pertimbangan apabila mikrokontroler digunakan sebagai instrument pada data logger. Salah satu sensor yang dapat digunakan untuk mengukur arus dan daya pada mikrokontroler adalah INA219. Pada penelitian ini, pengukuran konsumsi arus dan daya pada mikrokontroler berhasil dilakukan dengan tiga mode berbeda, yaitu run, blank dan deep sleep. Berdasarkan hasil pengukuran, mode deep sleep membutuhkan arus dan daya lebih kecil dibandingkan mode lainnya. Kemudian pada setiap mode, Arduino nano membutuhkan arus dan daya terkecil dibandingkan Arduino Uno, Arduino Mega 2560, Mega Robotdyn, Wemos D1 Mini, dan ESP 32 Dev Kit. Persentase penghematan daya mikrokontroler dari mode run ke mode deep sleep secara berurutan dari terbesar ke terkecil yaitu ESP 32 Dev Kit, Wemos D1 Mini, Robotdyn 2560, Arduino Nano, Arduino Mega2560, Node MCU ESP 12E, dan Arduino Uno. Fluktuasi nilai arus dan daya selama 1 menit diperoleh bahwa Arduino Mega2560 memiliki nilai fluktuasi paling besar dibandingkan mikrokontroler jenis lainnya dengan nilai standar deviasi paling besar pada mode run sebesar 7,55 dan 34,04.Current and power consumption on the microcontroller is one of the considerations when the microcontroller is used as an instrument in the data logger. One of the sensors that can be used to measure current and power on a microcontroller is the INA219. In this study, the measurement of current and power consumption on the microcontroller was successfully carried out with three different modes, namely run, blank and deep sleep. Based on the measurement results, the deep sleep mode requires less current and power than other modes. Then in each mode, Arduino nano requires the lowest current and power compared to Arduino Uno, Arduino Mega 2560, Mega Robotdyn, Wemos D1 Mini, and ESP 32 Dev Kit. The percentage of microcontroller power savings from run mode to deep sleep mode sequentially from highest to lowest, namely ESP 32 Dev Kit, Wemos D1 Mini, Robotdyn 2560, Arduino Nano, Arduino Mega2560, Node MCU ESP 12E, and Arduino Uno. The fluctuation of current and power values for 1 minute shows that Arduino Mega2560 has the highest fluctuation value compared to other types of microcontrollers with the highest standard deviation values in the run mode of 7.55 and 34.04
Pengisian Baterai Ion Litium dengan Variasi Arus Menggunakan Modul TP4056 dan TP5100
Get PDFThe charging speed of lithium-ion batteries depends on the applied current, with higher currents resulting in faster charging. However, higher currents can increase the surface temperature, potentially damaging components or causing safety hazards. This study measured the surface temperature of lithium-ion batteries using the DS18B20 sensor. The TP4056 module was used for currents of 880.9 mA, 982.30 mA, and 1134.40 mA, while the TP5100 module was used for a current of 1323.80 mA. Charging at 1328.38 mA required the shortest time, approximately 3-4 hours. Temperature measurements showed no significant increase across the range of 880.0-1328.38 mA. For 982.30 mA, the first and second measurements recorded maximum temperatures of 34.4 °C and 36.2 °C, respectively. In the third measurement at 1328.38 mA, the maximum temperature reached 35.5 °C. Overall, the temperature variations remained below the maximum safe limit for lithium-ion battery charging

No full textABSTRACT
Connotative meaning is a word that has sense of value. Generally
connotative meaning can be found in literary work, one of them is
song. Song have become ordinary thing to be heard at home or in
public places. This research aims to find out : 1) what are the types of
connnotative meaning contained in the Maher Zain Song lyrics? 2)
what are the message delivered in the Maher Zain song lyrics?.
This research was descriptive qualitative because the data were the
lyrics of Maher Zain song. There were some steps in collecting data
such as the researcher browsed the Maher Zain song that will be
annalyzed. watched and listened the Maher Zain song lyrics on
Youtube. Find the sentences which consist of connotative meaning.
Make a note which is one used connotative meaning. The analysis
continued by analyzing the connotative meaning. In data analysis, this
research used Miles and Huberman procedure, namely data reduction,
data display and conclusion drawing/ verification. The researcher use
validator to validity the data.
The result of this research were the researcher found that there are
three types of connotative meaning based on J.N. Hook Theory is a
positive, negative and neutral connotation in song lyrics "Forgive Me"
Album by Maher Zain. The researcher found twenty three Forgive me
song lyrics that contain connotative meanings including six positive
connotations , eleven neutral connotations , and six negative
connotations. From the explanation above, it can be concluded that the
most common type of Connotative Meaning that found in five Song
Lyrics "Forgive Me" Album by Maher Zain is neutral connotation.
Neutral connotation is most widely used in the lyrics of the song to
replace the actual meaning to make it more interesting and easier to
understand. From this analysis, the researcher found the message that
the author wanted to convey. there are one song about heartfelt
expression of love and gratitude towards Allah (God). the one song
about touching ode to the unconditional love and sacrifices made by
mothers, the one song about motivation, the one song about One Big
Family and the one heartwarming tribute to the love between a father
and his daughter. The message that conveyed by the author really
meaningfull and can give motivation and relate to many people, these

Performance Comparison of Polycrystalline Solar Cells with and Without Reflectors
Get PDFThis research aims to analyze the comparison of power output between Polycrystalline solar panels with and without the use of mirror reflectors. The growing demand for sustainable energy sources necessitates ongoing efforts to enhance the efficiency of photovoltaic (PV) technology. In this study, a comparative experimental design was implemented over a two-day period, utilizing two identical solar panel configurations: a Reflector Equipped-Solar Panel (RESP) and a Solar Panel Without Reflector (WRSP). The electrical parameters of both configurations, including voltage, current, and power output, along with temperature, were continuously monitored and analyzed. The results indicate that the RESP consistently outperformed the WRSP. On average, the RESP produced 28–35% higher electrical current, which directly translated into a 25–32% increase in power output compared to the WRSP. The peak power of the RESP reached 21.3 W, whereas the WRSP peaked at 16.2 W. Although the RESP operated at a higher temperature (approximately 5–7 °C greater than WRSP), the power gain from increased irradiance effectively outweighed the thermal losses. These findings provide strong empirical evidence that reflective augmentation is a viable and cost-effective method for enhancing the performance of standard solar panels, offering valuable insights for maximizing renewable energy harvesting

Get PDFCultural diplomacy is a form of public diplomacy. Cultural diplomacy focuses on all things that are considered cultural aspects, such as tourism and the arts. Brunei Darussalam is a country that has the potential for spending per visit, namely USD 870 per person, but in 2017-2018 the number of foreign tourist visits from Brunei Darussalam decreased. This research raises the research question "How does Indonesian Cultural Diplomacy increase the number of visits by foreign tourists from Brunei Darussalam 2017-2019?". To answer this question, the author uses the concepts of cultural diplomacy and nation branding. The Cultural Diplomacy carried out by Indonesia involves several parties, both state actors and non-state actors, who work together to promote Indonesian tourism by building nation branding as the main instrument of cultural diplomacy through exhibitions, art, idea promotion, and exchange. The results of this research show that cultural diplomacy efforts through programs held and participation in exhibitions have been proven to be able to increase the number of visits by foreign tourists from Brunei Darussalam. Apart from that, the promotions carried out have also increased Indonesia's image index in the accredited country of the Indonesian Embassy in Bandar Seri Begawan. All of these programs and activities have the aim of spreading Indonesian culture and establishing relationships with the public of Brunei Darussalam to create a positive tourism image while increasing the number of visits by foreign tourists from Brunei Darussalam
