Abstract

Energi berperan sangat penting dalam kehidupan manusia. Misalnya untuk proses industri, penerangan, dan masih banyak peralatan yang memerlukan energi agar dapat bekerja. Sebagian besar produksi energi berasal dari sumber energi fosil berupa minyak bumi dan gas alam. Berdasarkan data International Energy Agency (IEA), pada tahun 2018 produksi energi dunia adalah 14.421 Mtoe. Sebagian besar didorong oleh pembangkitan yang berasal dari bahan bakar fosil yaitu sebesar 370 Mtoe. Produksi energi yang berasal dari energi terbarukan dan nuklir juga meningkat, masing-masing sebesar 60 Mtoe dan 19 Mtoe. Bahan bakar fosil pada akhirnya menyumbang lebih dari 81% produksi energi pada tahun 2018. Berdasarkan hasil percobaan pada proses elektrolisis yang mempengaruhi jumlah produksi hydrogen adalah besaran voltase 18V pada proses electrolysis. Semakin besar tegangan elektrolisis maka semakin banyak gas hydrogen dan oksigen yang di hasilkan, hasil setiap pengujian yang dilakukan mulai dari percobaan pengujian menggunakan satu b dan menggunakan dua buah fuel cell serta perhitungan hasil gas hasil fuel cell generator selama 20 menit, perancangan alat hidrogen generator dan fuel cell memiliki sistem kerja yang cukup baik. Berdasarkan hasil percobaan pada satu fuel cell dalam waktu 50 menit menghasilkan tengangan maksimal sebesar 1,18V , sedangkan untuk percobaan kedua menggunakan dua buah fuel cell menghasilkan tegangan maksimal 2,39 V dalam waktu 50 menit.Maka dapat di simpulkan jumlah fuel cell ,gas hydrogen,dan oksigen mempengaruhi tegangan yang dapat di hasilkan. Kata Kunci : Fuel cell, Hydrogen, Oksigen, Renewable Energy, Elektrolisis.

Abstract

Skin health is essential for everyone. In addition to supporting someone who can reduce self-confidence, skin diseases can also interfere with a person's concentration in activities. An expert system is a system designed to be able to imitate the expertise of an expert in answering questions and solving a problem. The expert system will solve a problem obtained from a dialogue with the user. With the help of an expert system, someone who is not an expert can answer questions, solve problems, and make decisions that an expert usually makes. This needs to be anticipated and handled seriously, especially for types of skin diseases, some of which can be fatal, and some can even be classified as cancer. Experts are needed to diagnose each disease in this case, but consultation with experts requires costly funds. For this reason, this system is designed to help people diagnose skin diseases online, making it easier for sufferers to diagnose the diseases they suffer from by themselves. The method used is the fuzzy Tsukamoto method. Analysis of the introduction of the disease is carried out by identifying various symptoms of the disease. The types of diseases diagnosed include tinea versicolor [P001], scabies [P002], ringworm [P003], dandruff [P004], vitiligo [P005], pityriasis alba [P006], hives [P007], erythema multiforme [P008], acne [P009], keloids [P010], melanoma [P011], eczema [P012], boils [P013], measles [P014], psoriasis [P015], impetigo [P016], and herpes [P017]. Skin disease sufferers can diagnose their disease without consulting with a specialist directly. This system can be used as a substitute for a specialist in producing a diagnosis in the form of the name of the disease suffered by the system user (user). This system provides a solution for users regarding more economical disease diagnosis.

Abstract

In this modern era, the efficiency of electricity usage has become one of the main concerns in the efforts toward sustainable energy management. The limitations in monitoring electricity usage have become a challenge for technicians, resulting in inefficiencies in data collection and discrepancies between the actual power usage and manual recordings. This research aims to design and develop a prototype of an Internet of Things (IoT)-based electricity usage monitoring tool to monitor electricity consumption in real-time, provide usage cost estimates, and measure the emission levels generated by the devices being used. It also facilitates data recording, accelerates decision-making, and improves electricity management with high accuracy, with a margin of error of 0.8% for power calculations and 0.5% for total power calculations. This allows for accurate measurement of voltage, load, power, and total power. The data obtained is used to calculate electricity tariffs based on actual consumption, such as a subscription fee of IDR 127,134, a rate per kWh of IDR 528.76, and a tax of 4%, resulting in a total cost of IDR 132,768 for 0.366 kWh usage over 60 minutes. The use of electronic devices also increases carbon emissions, with a 69% increase in the first 10 minutes and 28% in 60 minutes, highlighting the importance of environmental awareness and wise electricity usage.
