Studi Eksperimen untuk Kondisi Tanpa Beban pada Pengering Ikan Tipe Greenhouse Aktif

Abstract

Among all available renewable energy sources, solar energy is the most abundant one and is available in both direct as well as indirect forms. People have applied solar energy as energy alternative in various fields. One of the field that use solar energy is drying. Drying is one of the best methods to preserve product like fish. Fish drying is practice to preserve the fish for longer duration. Entrapment of thermal energy from solar radiation may be the best option for fish drying by using closed drying (greenhouse). This study aims to determine the effect of inlet velocity of air to the thermal performance of greenhouse in the no-load conditions by considering several environmental parameters such as temperature, humidity and solar radiation. The half an hourly data for ambient temperature, outlet temperature, relative humidity of air, wind velocity, radiation intensity were taken inside and outside the greenhouse dryer. These data are used for the determination of thermal performance of active greenhouse dryer. From experimental results, it can be concluded that drying conditions with inlet velocity of air 0,8 m/s is more favorable than inlet velocity of air 1,6 m/s as obtained thermal efficiency of active greenhouse is higher.

Analisis Eksperimental Variasi Kecepatan Aliran Udara Panas Pada Proses Pengeringan Ikan Menggunakan Rumah Pengering Tipe UV Solar Dryer

“…Prinsip kerja dari pemanas Udara tenaga Surya yaitu dengan memanfaatkan tenaga energi radiasi matahari yang melewati kaca transparan dan diserap oleh absorber dan kemudian mengubah energi matahari yang diterima menjadi energi panas. Pengeringan mekanik dengan metode pengeringan ultra violet (UV) solar dryer dikombinasikan dengan system solar air heater sehinggga proses pengeringan dapat mendapatkan hasil yang maksimal [3][7] [8]. Sehubungan dengan hal ini, maka perlu untuk melakukan penelitian studi pengaruh pembebanan dan lama pengeringan ikan asin dihubungkan dengan kadar air dan laju pengeringan.…”

Introduksi GHE.VENT Dryer Pada Proses Pengeringan Ikan Di Pantai Lhok Seudu

“…Abdullah (2013) menyatakan bahwa alat pengering ikan tenaga matahari dapat dibuat dari atap transparan yang memiliki prinsip efek rumah kaca dan dapat juga menambahkan kolector surya sebagai penyerap panas matahari. Sidhi et al (2017), pengeringan dengan menggunakan pengering tertutup dengan tipe greenhouse aktif merupakan salah cara terbaik untuk proses pengawetan ikan.…”

“…However, fresh fish contains up to 80% water and is a highly perishable material (Bala and Mondol, 2001). If fresh fish is not directly consumed or processed into finished products, the fish will quickly decay and become waste (Sidhi et al, 2017). Prompt preservation of fish prevents decay and maintains the quality of the fish.…”
