Abstrak Saat ini konsumsi penggunaan energi fosil terus meningkat, sehingga gas hidrogen dianggap dapat menjadi salah satu pengganti energi fosil karena efek yang dihasilkan pada lingkungan sangat minim. Selain gas hidrogen ramah lingkungan ternyata energi pembakaran yang dihasilkan oleh gas hidrogen besarnya mencapai sekitar 286 kJ/mol. Akan tetapi gas hidrogen tidak dapat ditemukan secara bebas oleh karena itu akan diproses menggunakan metode elektrolisis air. Saat ini proses elektrolisis banyak digunakan untuk dikembangkan sehingga dapat menghasilkan gas hidrogen. Proses elektrolisis banyak digunakan karena proses ini merupakan proses penguraian molekul air yang sederhana dan digunakan untuk mendapatkan gas hidrogen dengan tingkat kemurnian tinggi. Proses elektrolisis air banyak memiliki kekurangan karena membutuhkan energi yang besar oleh karena itu perlu penelitian lebih lanjut. Faktor-faktor yang mempengaruhi efisiensi untuk terbentuknya gas hidrogen yaitu katalis, suhu, tekanan, dan jenis elektroda yang digunakan. Sehingga pada jurnal ini akan dibahas perbandingan dari dua jenias elektroda terhadap laju produksi dari hidrogen. Keywords: elektrolisis air, energi terbarukan, produksi gas hidrogen, elektrolit Abstract Currently the consumption of fossil energy continues to increase, so hydrogen gas is considered to be one of the substitutes for fossil energy because the effects to the environment are very minimal. Hydrogen is environmentally friendly and turns out that the combustion energy produced by hydrogen gas reaches about 286 kJ / mol. However, hydrogen gas cannot be found freely and in this paper we will using water electrolysis method to get the hydrogen gas. The electrolysis process is widely used because this process is a simple process of decomposing water molecules and can obtain hydrogen gas with high purity. The process of electrolysis of water has many disadvantage because it requires a large amount of energy and needs further research. The factors that influence the efficiency for the formation of hydrogen gas are the catalyst, temperature, pressure, and type of electrodes used. So this paper will discuss the comparison of the two types of electrodes that is graphite and copper that coated in aluminium, to the rate of production of hydrogen. Keywords: water electrolysis, renewable energy, hydrogen production, electrolyte

Abstrak Melimpahnya ketersediaan air laut di dunia mendorong para peneliti untuk terus mengembangkannya menjadi energi yang bisa digunakan oleh umat manusia. Salah satu dari pemanfaatan air laut adalah dengan mengubah nya menjadi hidrogen. Hidrogen dengan mudah dapat diproduksi dan tahan lama dari air laut. Hal ini menunjukan air laut memiliki potensi besar sebagai pengganti bahan bakar fosil yang sampai saat ini masih digunakan. Pada penelitian ini, peneliti melakukkan studi untuk menganalisis hasil-hasil penelitian yang sudah dilakukan untuk memaparkan potensi air laut sebagai sumber energi terbarukan. Kata Kunci: Air laut,Hidrogen,Elektrolisis,Energi Abstract The abundant availability of sea water in the world encourages researchers to continue to develop it into energy that can be used by humanity. One of the uses of sea water is to convert it into hydrogen. Hydrogen can easily be produced and is durable from seawater. This shows that seawater has great potential as a substitute for fossil fuels which are still used today. In this study, researchers conducted a study to analyze the results of research that has been done to explain the potential of sea water as a renewable energy source. Keywords: Sea water, Hydrogen, Electrolysis, Energy

This research explores the effectiveness of Interactive Digital Module Physics (IDMP) for additional teaching materials in vector concepts. The IDMP which was developed according to the ADDIE model and its implementation uses the Interactive Lecture Demonstration (ILD) learning model. A total of 65 participants were students enrolled in a Basic Physics course at a university in a special area in the central district of Indonesia. The instrument used to validate the IDMP uses a scale of 1-5 and has a scoring rubric and processing effectiveness data using technique Cohen's D formula. The intervention group was given training assignments in using ILD-based IDMPs while the control group was given ILD-based assignments only. The results of this study obtained data that the intervention group was significantly better than the control group, found there was no significant increase. Cohen's D score in the intervention group had a large impact on the control group of 1.17 with a 95% confidence interval. Furthermore, they get learning experience by providing feedback that the course material using ILD-based IDMP can challenge students to learn independently.
