Penelitian tentang distiller tenaga surya sistem kontinue untuk mengetahui unjuk kerja distiler tersebut telah dilakukan. Tiga buah distiller yaitu distiller dengan kaca penutup tunggal, ganda dan rangkap tiga telah dirancang dan diuji.Material yang diuji adalah air laut berasal dari pantai Tanjungkarang, Mataram, NTB yang diubah menjadi air tawar melalui proses distilasi.Ukuran distiller yang diuji adalah 1136 mm x 936 mm x 574 mm (bagian luar), sedangkan ukuran plat penyerap panasnya adalah 0,8 m x 1 m. Penelitian dilakukan pada bulan Juli 2019 dari jam 09.00 WITA hingga jam 16.00 WITA. Hasil menunjukan bahwa semakin banyak jumlah kaca penutup semakin sedikit air tawar yang diproduksi. Distiller dengan kaca penutup rangkap tiga lebih panas sehingga uap air tidak dapat mengembun. Oleh sebab itu, distiller dengan kaca penutup tunggalah yang direkomendasikan untuk digunakan.

Now days, a company has been experiencing and facing a tight competitive siege. To be surviving within this competition, the company must be creative in developing new and robust ideas to improve their business competitiveness which differentiate them from the others. The product quality was the main issues among others. The quality of a product that offered to the consumers must be cheap and have met with consumer satisfaction. Exploring these ideas, current research has conducted with the main goal was investigating the quality of product produced on CNC Turning. The quality was calculated with a Statistical Process Control (SPC) analysis. Meanwhile, ductile iron workpieces size of 130 mm in length and 19 mm in diameter were manufactured for the samples. The data gathered including diameter, length, and thickness of the samples measured with Digital Vernier Caliper and Micrometer. Based on data observed, the result of experiment shows that the quality of sample products produced in single run (12 products) has met with basic standard requirement with which all samples dimension was lay inside the control limit (Upper and Lower Control Limit (UCL and LCL). It can be concluded that each variable still in process control and was ready for the automation.

ABSTRACTDue to population growth, industry advance and rapid development, fresh and comfortable air may be difficult to get. Conditioning the air to get comfort environment may be a basic demand for people, but the prices of the device and its operation for this purpose are expensive. This research tries to solve this problem but it is just only to know the capability of the heat exchanger to transfer/ absorb heat and is not to cool the room to be below the ambient temperature. The working fluid used was clean water and the heat exchangers employed were parallel and serpentine which were made of copper pipes with a diameter of 1/4 inch and 1/2 inch (for the header). The volumetric flow rates used were 300 ml/minutes, 400 ml/minutes and 500 ml/minutes. While the heat that should be absorbed by the water from the room is 50 W, 100 W and 150 W. The results show that the effect of volumetric flow rate on heat exchanger performance and room temperature is insignificant. From the pressure drop results, the parallel pipe heat exchanger has lower pressure drops while the serpentine has higher pressure drops.
