Abstract

The sprinkler irrigation system of horticultural agriculture at Universitas Samudra is able to increase the efficiency of water use when the climate change phenomenon hits. However, sprinkler irrigation requires quite high operational investment costs. The purpose of the planning is to obtain the design of the sprinkler irrigation network and optimize the operational investment costs of irrigation. The method used is hydraulic simulation of irrigation using variations in centrifugal and submersible transfer pump power and PVC pipe size. Furthermore, the results of the irrigation simulation were analyzed using the Taguchi method. The planning results show that the sprinkler irrigation network covers an area of 7,500 with an elevation of 6-8 meters above sea level. The water requirement for 53 sprinklers is 8.48 liters/second, and the total water requirement for horticultural plants is 2,063.2 per season. The use of a combination that can optimize the operational investment costs of irrigation is the use of centrifugal transfer pump power (0.6 kW), submersible transfer pump power (0.6 kW), and PVC pipe sizes of 1/2, 1, 1 1/2, and 2 inches. This combination produces an optimum water pressure prediction of 1.756 bars and produces an optimum electricity usage cost prediction per day of Rp. 30,350. By using centrifugal transfer pump power, submersible and low-capacity PVC pipe size makes it more cost-efficient compared to other combinations.

Abstract

This study investigates the effect of Phase Change Material (PCM) on temperature, efficiency, and productivity. The prototype solar distillation system is tube-shaped, with a length of 50 cm and a diameter of 4 inches, using a parabolic trough collector. The PCM used is beeswax, which is wrapped in aluminum foil. The results show that the use of PCM improves freshwater productivity. On the first day, the PCM method showed an 11% increase in production, and on the second day, freshwater production increased by 13%. The production rate with PCM was 0.76 L/m²/day, compared to the conventional method, which had a rate of 0.67 L/m²/day. The system with PCM also achieved high efficiency, reaching 11,47% on the first day and 13,9% on the second day. The system remained stable in the afternoon and evening, maintaining temperatures above 35 °C at night, compared to the system without PCM, where the temperature dropped to 30 °C. The use of PCM significantly enhanced the overall performance of the distillation system.
