Abstract
Perkembangan teknologi yang sangat pesat mempengaruhi gaya hidup yang beriringan dengan konsumsi energi. Seiring bertambahnya pertumbuhan penduduk dan ekonomi juga mempengaruhi konsumsi energi pada setiap sektor, terutama di sektor komersial dengan konsumsi energi paling besar berasal dari sistem pendinginan dan sistem pencahayaan. Di sisi
lain, besarnya penggunaan konsumsi energi menunjukkan bahwa penggunaan energi listrik di Indonesia masih bergantung pada sumber energi fosil seperti batubara, gas, dan minyak yang
menjadi sumber energi utama Indonesia sehingga perlu adanya pemanfaatan energi terbarukan, salah satunya panel surya di mana potensi pemanfaatannya yang cukup besar. Lantai I Gedung Departemen Teknik Mesin ITS merupakan salah satu penggunaan konsumsi energi yang cukup besar dan kurangnya pemanfaatan akan panel surya. Hal tersebut menandakan perlu adanya penghematan energi dengan mencari peluang penghematan dari sistem pencahayaan dan sistem pendinginan serta perancangan panel surya berdasarkan konsumsi energi di lantai I Gedung Departemen Teknik Mesin ITS. Sistem pencahayaan mengacu pada standar SNI dan sistem pendinginan mengacu pada standar ASHRAE menggunakan metode CLTD serta pada perancangan panel surya dilakukan simulasi menggunakan aplikasi Pvsyst dengan memvariasikan sudut agar mendapatkan peluang penghematan energi terbesar. Hasil menunjukkan nilai intensitas pencahayaan seluruh ruangan masih belum memenuhi standar SNI dan nilai daya pencahayaan yang sudah memenuhi standar SNI pada seluruh ruangan sehingga tidak adanya peluang penghematan energi. Namun, perekomendasian tetap dilakukan agar dapat memenuhi kekurangan intensitas pencahayaan yaitu dengan menambah jumlah lampu berdasarkan kekurangan lumen dan standar SNI dari setiap jenis ruangan. Pada sistem pendinginan, total beban pendinginan seluruh ruangan adalah 621.254,3632 Btu/h sehingga diperlukan penghematan energi dengan merekomendasi penggantian kaca menjadi double glass dan penambahan tirai yang dapat menghemat 22,61% dari total beban pendinginan dan penggantian kapasitas AC yang dapat menghemat sebesar 54% dari total beban pendinginan. Pada perancangan panel surya, hasil simulasi menunjukkan sudut terbaik untuk mendapatkan
penghematan energi yaitu pada sudut 10° sebesar 171725 kWh/tahun pada sistem on-grid dan sebesar 200905 kWh/tahun pada sistem off-grid karena menghasilkan produksi energi yang maksimal. Peluang penghematan energi dan biaya terbesar pada panel surya adalah pada sistem on-grid pada sudut 10°. Hal tersebut dikarenakan sistem off-grid menghasilkan biaya yang sangat besar.

The development of technology significantly influences lifestyles along with energy consumption. As population and economic growth also affect energy consumption in every
sector, especially in the commercial sector with the largest energy consumption coming from the cooling system and lighting system. On the other hand, the large use of energy consumption shows that the use of electrical energy in Indonesia still depens on fossil energy source such as
coal, gas, and oil which are Indonesia’s main energy sources so that it is necessary to utilize renewable energy, one of which is solar panels where the potential for utilization is quite large. The first floor of the Mechanical Engineering Department Building ITS is one of the use of considerable energy consumption and the lack of utilization of solar panels. This indicates the need for energy savings by looking for savings opportunities from the lighting system and cooling system and designing solar panels based on energy consumption on the first floor of the Mechanical Engineering Department Building ITS. The lighting system refers to the SNI Standard and the cooling system refers to the ASHRAE standard using CLTD method and the design of solar panels is simulated using PVsyst application. The results show that the lighting intensity value of the entire room still does not meet the SNI standard and the lighting power value that has met the SNI standard in all rooms so that there is no opportunity for energy savings. However, recommendations are still made in order to meet the lack of lighting intensity, namely by increasing the number of lamps based on the lack of lumens and SNI standards of each type of room. In the cooling system, the total cooling load of the entire room is 621.254,3632 Btu/h so that energy savings are needed by recommending the replacement of glass to double glass and the addition of curtains which can save 22.61% of the total cooling load and replacement of air conditioning capacity which can save 54% of the total cooling load. In the design of solar panels, simulation results show the best angle to get energy savings is at
an angle of 10 ° of 171725 kWh/year in the on-grid system and 200905 kWh/year in the off-grid system because it produces maximum energy production. The largest energy and cost saving opportunity on solar panels is in the on-grid system at an angle of 10°. This is because the offgrid system generates enormous costs.
