Abstract

At this time the government prohibits the use of antibiotics in animal feed as a growth promoter (AGP) or antibiotic, so an effective and safe immunomodulator and herbal growth stimulant product are needed through Meniran extract products (Phyllantus niruri) and chemicals in the market are not yet optimal as immunomodulators and growth stimulants. CV. Maxipro Agrosatwa which is engaged in veterinary medicine, wholesale trade of agricultural products, and other live animals will produce feed using Meniran extract products. Extraction equipment that is needed is a Rotary vacuum evaporator. This equipment is needed to separate the solvent from the solute without high heating which will damage the solute content. The vacuum condition in the flask is to make the separation more efficient as well as accelerate the separation of the solvent from a solution by reducing the boiling point. The rotation of the flask is to increase evaporation. The complexity of this equipment is what makes CV. Maxipro Agrosatwa cannot handle it alone and requires technical assistance from the Department of Mechanical Engineering (JTM) FT UNS. Technical assistance provided by JTM FT UNS is in the form of procurement, delivery, installation, operation, and maintenance of the rotary vacuum evaporator.

Abstract

Abstrak — Kebutuhan energi listrik yang tinggi pada bangunan komersial seperti pusat perbelanjaan menyebabkan biaya operasional yang besar dan ketergantungan penuh pada sumber energi konvensional. Gedung Delta Plaza Surabaya, sebagai salah satu pusat perbelanjaan besar hingga saat ini masih sepenuhnya bergantung pada pasokan listrik dari PLN. Penelitian ini bertujuan untuk menganalisis potensi penghematan energi dan biaya melalui penerapan sistem Pembangkit Listrik Tenaga Surya (PLTS), serta mengevaluasi kelayakannya dengan pendekatan Levelized Cost of Energy (LCOE). Metode yang digunakan melibatkan konversi konsumsi energi tahunan menjadi kapasitas PLTS, perhitungan investasi, produksi energi, hingga proyeksi ekonomi jangka panjang. Hasil menunjukkan bahwa sistem PLTS dengan kapasitas 4.622,102 kWp mampu menghasilkan 7 juta kWh per tahun dengan LCOE sebesar Rp 425,82/kWh, lebih rendah dibandingkan tarif PLN Rp 1.035,78/kWh. Potensi penghematan mencapai 58,9% atau sekitar Rp 4,69 miliar per tahun dengan waktu pengembalian modal sekitar 11 tahun 7 bulan. Kesimpulan pada penelitian ini sistem PLTS dinilai layak secara teknis dan ekonomis untuk diterapkan sebagai strategi efisiensi energi jangka panjang. Kata kunci— Delta Plaza, Energi terbarukan, Efisiensi energi, Levelized Cost of Energy (LCOE), PLTS.
