Vanadium Redox Flow Battery (VRFB) is a relative new type of secondary battery that has ability as Energy Storage System (ESS) for renewable energy power plants such as solar cell. 2D VRFB single cell was modeled using COMSOL Multiphysics software and simulated numerically by using Nernst-Planck, secondary current distribution, tertiary current distribution and Buttler-Volmer principle. Simulation was conducted at 293,15 K, with electrode thickness variations of 1 mm (L1), 2 mm (L2), 3 mm (L3), 4 mm (L4) and 5 mm (L5). According to the simulation results, it is known that electrolyte potential in negative electrode is higher than positive electrode and the distribution is tend to decrease for all variations. Surface concentration near collector is dominant during charging compare inlet position and the reverse phenomenon occur during discharging process. VRFB L1 show weak performance and VRFB L2 show the best performance in term of electrolyte potential and species molarity in the electrode surface.

This research aims to determine the energy efficiency of lead acid batteries after testing the charge-discharge process with a constant current method. Charge-discharge current variations of 0.3 A, 0.5 A, and 0.6 A. The performance voltage range when the charging process has a value in comparison with the charging current. The greater the charging electric current can change the voltage range of the greater performance. Conversely, at the discharge process. The greater the discharge electric current can change the performance voltage range the smaller. Meanwhile, in the performance voltage range the discharge process is lower if the discharge flow gets bigger. Based on the results of the charge-discharge process test, it can be determined the energy efficiency values of the current variation of 0.3 A, 0.5 A, and 0.6 A, which are 76.32%, 76.06% and 91.33%, respectively.

Energy storage systems (ESS) with large storage capabilities, easy made, and low cost are in high demand. Dynamic lead acid battery (DLAB) as a breakthrough design compared conventional lead acid batteries offers a solution to these problems. Two Dimensional (2D) DLAB simulations with surface area variations of 8 cm2, 12 cm2, 16 cm2 and 20 cm2 were successfully build using the principle of tertiary current distribution and Nerst-Planck Interface. The results for one cycle charge-discharge test showed that the increase in surface area succeeded in increasing the final charging voltage with a value of 2.16 V; 2, 21 V; 2.30 V and 2.32 V and increase the initial discharging voltage by a value of 1.58 V; 1.59 V; 1.60 V and 1.62 V respectively but did not affect the electrode surface concentration. Dynamic lead acid battery has high energy efficiency of 70.6% -71.5%.

: Prospective physics teachers are the seeds of the next generation to spread science. But the understanding of science has been balanced with standard laboratory facilitation. In fact there are still many public and private schools that do not have adequate laboratory facilities. Whereas a physics teacher candidate must be able to teach in all fields and conditions. This is a challenge for prospective physics teachers. So the importance of conducting workshops to conduct a learning approach using methods of using practicum media by optimizing the surrounding environment such as the use of passive and active electrical component materials. The implementation of this activity is carried out for six hours consisting of 1. Introduction 2. Characterization 3. Implementation. The results of this dedication activity the prospective physics teachers are very enthusiastic because so far the physics candidates are only limited to knowing but do not understand the physical or physical meaning.

Abstract—Telah dilakukan simulasi 1D plasma Argon dengan mengggunakan pembangkit DC Bias. Simulasi dilakukan menggunakan software Comsol Multiphysics dimana pada simulasi asumsi suhu dijaga konstan 400K dan tekanan rendah dibawah 80 Pa. Simulasi dilakukan untuk mengetahui distribusi plasma Argon di dalam chamber ketika generator DC Bias diaplikasikan pada gas netral Argon di dalam chamber. Hasil simulasi menunjukkan bahwa distribusi densitas plasma (ne, ni) tertinggi diketahui terletak sangat dekat dengan elektroda negatif dan semakin mengecil secara eksponensial menuju ground. Hal ini di dukung juga dari distribusi temperatur elektron (Te) yang memiliki tren yang sama. Pada variasi tekanan diketahui bahwa dengan menaikkan tekanan gas di dalam chamber mampu menaikkan densitas plasma secara linear. Kata Kunci— Comsol Multiphysics, Plasma, Plasma Argon dan DC Bias Discharge.

Baterai dinamis atau yang dikenal dengan Redox Flow Battery (RFB) merupakan jenis baterai sekunder yang banyak dikembangkan karena kemampuannya untuk menyimpan energi dalam jumlah besar. Pada penelitian ini, dikembangkan baterai dinamis berbasis asam timbal dimana timbal (Pb) dan timbal dioksida (PbO2) digunakan sebagai elektroda baterai dengan luas permukaan pelat (13,5 x 7,5) cm2. Baterai dinamis asam timbal diuji sehingga diketahui pengaruh perbedaan konsentrasi H2SO4 terhadap karakteristik baterai. Variasi konsentrasi H2SO4 yang digunakan adalah 20% dan 30%. Pengujian siklus pengisian-pengosongan dilakukan dengan alat BMS (Battery Management System) yaitu Turnigy Accucell-6 sebanyak 3 siklus dengan arus pembebanan 1 A. Berdasarkan hasil penelitian, kapasitas baterai dinamis asam timbal meningkat dengan meningkatnya konsentrasi H2SO4. Baterai dinamis asam timbal 30% menghasilkan kapasitas rata-rata tertinggi yaitu 4.657 mAh dengan efisiensi rata-rata 82,90%. Baterai dinamis 30% diuji masing-masing 1 siklus dengan variasi waktu pengisian untuk mengetahui waktu pengisian optimal baterai. Variasi waktu pengisian yang digunakan adalah 0,5; 1; 1,5; 2; 2,5 jam serta pengisian hingga titik cut-off . Hasil penelitian menunjukkan bahwa kapasitas baterai meningkat dengan meningkatnya waktu pengisian baterai, dengan efisiensi tertinggi baterai dinamis 30% adalah pada pengisian 2 jam.

Peningkatan kekerasan paduan baja dapat dilakukan dengan meningkatkan kandungan karbon dipermukaanya. Baja AISI 316 L yang memiliki kekerasan awal 189 HV300 dapat ditingkatkan kekerasannya melalui peningkatan jumlah karbon dipermukaan dengan metode pack carburizing. Pada penelitian ini kayu mahoni digunakan sebagai sumber karbon aktif yang diperoleh dengan pemanasan dan pengayakan 150 mesh. Pack carburizing dilakukan pada suhu tinggi yakni 700oC, 750oC, 800oC dan 850oC selama 8 dan 16 jam yang kemudian dilakukan uji kekerasan menggunakan micro vickers hardness tester. Semua spesimen hasil pack carburizing mengalami kenaikan kekerasan dibandingkan dengan spesimen tanpa perlakuan dengan range kenaikan sebesar 24-367 HV3. Kekerasan tertinggi diperoleh pada pemanasan selama 16 jam pada suhu 700oC. Hasil pengujian sudut kontak menunjukkan adanya perubahan sifat pada permukaan dari hidrofilik ke hidrofobik untuk semua sampel sementara dari hasil mikroskop optik diperoleh distribusi ukuran butir kurang dari 60 µm dengan dominan range 15-25 µm.

Natural Sciences (IPA) subjects often demand the logic of students in translating science concepts through laboratory practicum analysis for schools with complete laboratory facilities. However, for schools that lack complete laboratory facilities and do not even have a laboratory, it will be difficult to realize practical learning to support students' critical thinking processes. Especially in the midst of the Covid-19 pandemic which demands distance learning, educators find it difficult to express the aims and objectives of scientific theory which will be easier to understand if applied through practical learning. This community activity program aims to provide solutions to science teachers through training in the use of practicum-based interactive media using the proteus software application. It consists of three stages of implementation, namely preparation, implementation and evaluation. The results of the community service activities obtained are that science teachers obtain transfer of technological knowledge using interactive learning media through the proteus simulation software application and analyze the results of circuit analysis simulations in the dynamic electricity sub-chapter.
