Abstract

The fossil energy utilization for electricitygeneration is currently starting to be limited because it is predictedthat the availability of fossil energy for the next few decades willrun out. Renewable energy is an alternative energy that can beused to generate electricity. Solar power plant is one of theelectrical energy generators with renewable energy sources thathave been widely used. Solar power plant is a DistributedGenerator that can be applied directly to consumers and it is verysuitable for use in remote areas which currently still use diesel asa fuel for power generation. In this research, the design of a hybridpower generation system between Soalr Energy and Wind will becarried out to replace the use of diesel as a source of electricitygeneration. After the generator design is done, then theperformance test of the hybrid system will be carried out in orderto see the feasibility of the design that has been made. From thetest results, the results of the Hybrid Energy Generator haveefficiencies ranging from 10-12% where this shows that the powerplant system is still said to be unable to work efficiently. Theaverage amount of energy produced from this Hybrid PLT systemis 1,304 kWh per day. Based on the results of the economicfeasibility analysis, that the use of the hybrid system is able toproduce savings of Rp. 1,700 ”“ Rp. 2,100/kWh per day

Abstract

Produksi bioetanol sebagai alternatif energi terbarukan semakin penting untuk mendukung keberlanjutan energi hijau. Namun, proses produksi bioetanol dari bahan baku konvensional masih menghadapi tantangan terkait efisiensi dan dampak lingkungan. Mikroalga, seperti Chlorella vulgaris dan Spirulina platensis, menawarkan potensi sebagai sumber karbohidrat untuk bioetanol, namun optimasi produksinya masih diperlukan. Penelitian ini bertujuan untuk mengoptimasi produksi bioetanol menggunakan kedua mikroalga tersebut melalui simulasi perhitungan biomassa, kandungan karbohidrat, dan potensi bioetanol selama 100 hari. Hasil simulasi menunjukkan bahwa Chlorella menghasilkan biomassa 500 g/L dan potensi bioetanol 63.75 g/L pada hari ke-100, sedangkan Spirulina menghasilkan biomassa 400 g/L dan potensi bioetanol 40.80 g/L. Temuan ini memberikan wawasan penting tentang potensi mikroalga sebagai solusi energi hijau yang ramah lingkungan dan berkelanjutan, serta membuka peluang untuk penelitian lanjutan dalam mengoptimalkan proses produksi bioetanol dengan variabel lingkungan yang lebih beragam dan skala yang lebih besar.
