Pengujian Kinerja Sistem Pendingin Pada Prototipe Kapal Tanpa Awak Platform Supply Vessel Dengan Engine Zenoah Tipe G32fc
ABSTRACT
This research presents the performance testing of the cooling system on an unmanned ship prototype using a Zenoah engine type G32FC. This research aims to see the impact produced when using a radiator cooling system on engine performance and ship performance. The experiment was conducted using a platform supply vessel (PSV) prototype with a monohull design, measuring 120 cm in length and 35.15 cm in width. The Zenoah G32FC engine is a 2-stroke engine with a capacity of 31.8 cc, serving as the main propulsion unit of the prototype. Two types of coolant fluids were tested: water and radiator coolant. The results showed that the use of a radiator significantly improved engine temperatur control compared to not using a radiator, with an average test temperatur of 64.3°C and a peak temperatur of 71.6°C. The radiator coolant achieved the highest effectiveness of 57.6% with a heat transfer rate of 341 watts. The vessel's speed remained relatively constant across all tests, indicating that the use of a radiator had minimal impact on speed but was effective in maintaining engine temperatur. Therefore, the use of a radiator is highly recommended to optimize engine performance.
