Abstract

Masyarakat pesisir di Indonesia mendapatkan air tawar dengan cara membeli. Sehingga mereka harus menyiapkan biaya untuk membeli air tawar disamping biaya untuk kebutuhan sehari-hari. Jika air payau yang terdapat pada mata air di rumah-rumah dapat diubah menjadi air tawar, maka biaya yang dikeluarkan oleh masyarakat pesisir akan menjadi lebih murah. Penelitian ini dititik beratkan pada performansi alat destilasi penghasil air tawar menggunakan sistem evaporasi uap tenaga surya dengan menganalisa Intensitas matahari terhadap distribusi temperatur, daya pada apparatus, sudut kemiringan panel dan effisiensi dari apparatus. Analisa didapat menggunakan variabel manipulasi pada sudut kemiringan apparatus (θ pada 20o, 21o, 22o, 23o san 24o) dan volume apparatus pada kondisi ½ penuh dan ¾ penuh. Pada percobaan yang dilakukan, diperoleh hubungan antara Intensitas Matahari dengan distribusi temperatur, daya evaporator (Qnett), sudut kemiringan panel (θ) dan effisiensi evaporator (η) dari panel apparatus mengalami fluktuasi dan mengalami titik balik maksimum pada sudut 20o pada volume tube ½ penuh dan ¾ penuh. Pada sudut kemiringan 20o dengan volume tube ½ penuh dan temperatur lingkungan 36oC, diperoleh distribusi temperatur pada kaca 49oC, temperatur udara 59oC dan temperatur tube luar 67oC. Pada sudut kemiringan 20o dengan volume tube ¾ penuh dan temperatur lingkungan 34oC, diperoleh distribusi temperatur pada kaca 48oC, temperatur udara 60oC, Temperatur tube luar 68oC. Berdasarkan hasil perhitungan pada sudut 20o dengan volume tube ½ penuh diperoleh hasil Intensitas matahari sebesar 1603,497 watt/m2 sehingga diperoleh daya evaporator sebesar 434,67 watt dan temperatur air pada tube 64,7oC dengan effisiensi evaporator 92% . Hasil perhitungan pada sudut 20o dengan volume ¾ penuh diperoleh hasil Intensitas matahari sebesar 1803,545 watt/m2 diperoleh daya evaporator sebesar 498,48 watt dan temperatur air pada tube 65,37oC dengan effisiensi evaporator 93%. ==================================================================================== Coastal communities in Indonesia get fresh water by way of purchase. So they have to prepare a cost to purchase in addition to the cost of fresh water for daily needs. If the brackish water found in springs in homes can be converted into fresh water, the costs incurred by the coastal communities will becomes cheaper. This research emphasis on the performance of the distillation equipment producing fresh water using solar steam evaporation system by analyzing the intensity of the sun on the temperature distribution, power apparatus, panel tilt angle and the efficiency of the apparatus. Analysis obtained using the variable manipulation on the angle of the apparatus (θ at 20o, 21o, 22o, 23o 24o) and the volume of the apparatus on the condition of full ½ and ¾ full. In the experiment, the obtained relationship between the intensity of the sun with the temperature distribution, power the evaporator (Qnett), panel angle (θ) and evaporator efficiency (η) of the apparatus panel has fluctuated and had a maximum turning point at an angle of 20o to the tube ½ full volume and ¾ full. At the angle of 20o with the tube ½ full volume and ambient temperature 36oC, the temperature distribution in the glass obtained 49oC, 59oC air temperature and outdoor temperature 67oC tube. At the angle of 20o with volume tube ¾ full and 34oC ambient temperature, the temperature distribution in the glass obtained 48oC, 60oC air temperature, outside temperature 68oC tube. Based on the calculation at an angle of 20o with the volume of tube ½ full sun intensity results obtained by 1603.497 watt/m2 in order to obtain power of 434.67 watt and evaporator water temperature at the evaporator tube 64,7oC with 92% efficiency. The results of the calculation at an angle of 20o with the results obtained volume ¾ full sun intensity at 1803.545 watt/m2 was obtained at 498.48 watt power evaporators and the water temperature at the evaporator tube 65,37oC with 93% efficiency.
