Abstract

Pertumbuhan jumlah penduduk di Indonesia menyebabkan peningkatan konsumsi energi listrik, terutama dalam sektor rumah tangga. Sebagian besar pembangkit listrik di Indonesia saat ini masih menggunakan bahan bakar fosil sehingga peningkatan konsumsi energi listrik akan memicu peningkatan konsumsi bahan bakar fosil. Antisipasi harus segera dilakukan karena besarnya pelepasan senyawa karbon dioksida akibat peningkatan konsumsi bahan bakar fosil akan memperbesar dampak buruk dari pemanasan global. Dengan demikian, diperlukan upaya untuk meminimalkan konsumsi energi listrik pada sektor rumah tangga. Konsumsi energi listrik terbesar dalam sektor rumah tangga adalah untuk mengoperasikan AC sehingga upaya mengondisikan kenyamanan termal ruangan untuk mengurangi jangka waktu pengoperasian AC dapat dilakukan. Hal tersebut dapat diwujudkan melalui building energy retrofitting, khususnya pada rumah tangga middle low income. Retrofitting merupakan upaya untuk mencapai penghematan konsumsi energi listrik pada sebuah hunian. Dengan begitu, masyarakat middle low income akan sangat terbantu dalam menghemat biaya pengeluaran. Pada penelitian ini, retrofitting dilakukan dengan menerapkan Phase Change Material pada sisi permukaan dalam dinding hunian. PCM diharapkan mampu menghambat laju perpindahan panas yang terjadi pada dinding bangunan. Penelitian ini menggunakan 3 jenis PCM, yaitu Capric Acid, n-Eicosane, dan P116. Penelitian ini dilakukan berbasis simulasi dengan metode Computational Fluid Dynamics, menggunakan software ANSYS R18.1. Setelah dilakukan simulasi, diperoleh penurunan temperatur dalam ruangan yang paling besar adalah ketika menerapkan PCM jenis Capric Acid, yaitu dengan penurunan temperatur rata-rata dalam ruangan sebesar 2,542oC. Setelah itu, dilakukan cost-benefit analysis untuk menghitung selisih konsumsi listrik sebelum retrofitting dan setelah retrofitting. Berdasarkan cost-benefit analysis, pada beberapa variasi retrofitting, diperoleh penghematan konsumsi energi listrik sebesar 230,4 kWh sehingga diperoleh penghematan biaya konsumsi listrik dengan tingkat penghematan berdasarkan pada nilai inflasi sebesar 1,87%.

Population growth in Indonesia has led to an increase in the consumption of electrical energy, especially in the household sector. Most power plants in Indonesia currently still use fossil fuels, so the increase in electricity consumption will trigger an increase in fossil fuel consumption. Anticipation must be done immediately because the large release of carbon dioxide compounds due to increased consumption of fossil fuels will magnify the adverse effects of global warming. Thus, efforts are needed to minimize the consumption of electrical energy in the household sector. The largest consumption of electrical energy in the household sector is to operate the air conditioner so that efforts to condition the thermal comfort of the room to reduce the operating time of the air conditioner can be made. This can be realized through building energy retrofitting, especially in middle-low income households. Retrofitting is an effort to achieve savings in electrical energy consumption in a dwelling. That way, middle-low income people will be greatly helped in saving expenses. In this study, retrofitting was carried out by applying Phase Change Material on the inner surface of the residential wall. PCM is expected to be able to inhibit the rate of heat transfer that occurs in the walls of the building. This study used 3 types of PCM, namely Capric Acid, n-Eicosane, and P116. This research was conducted based on a simulation using the Computational Fluid Dynamics method, using ANSYS R18.1 software. After the simulation, it was found that the largest decrease in indoor temperature was when applying PCM type Capric Acid, that is, with a decrease in the average indoor temperature of 2,542oC. After that, a cost-benefit analysis was carried out to calculate the difference in electricity consumption before retrofitting and after retrofitting. Based on the cost-benefit analysis, in several variations of retrofitting, the savings in electricity consumption of 230.4 kWh are obtained so that the savings in electricity consumption costs are obtained with the savings rate based on the inflation value of 1.87%.
