Abstract

Keterampilan terkait perawatan AC Split sangat penting dalam kehidupan sehari-hari. Tantangan masa depan menuntut seluruh lapisan masyarakat, baik di tingkat sekolah menengah maupun generasi muda, untuk terus meningkatkan keterampilan teknis guna meningkatkan taraf hidup mereka. Lahirlah ide kegiatan pelatihan pencegahan kebocoran pipa pada saat perawatan AC Split kepada remaja Masjid PC LDII Kecamatan Gunung Anyar Surabaya. Dengan dukungan penuh dari sivitas akademik Politeknik Perkapalan Negeri Surabaya (PPNS), tim yang terdiri dari dosen, karyawan, maupun mahasiswa, bekerja sama dan berkontribusi dalam kegiatan pengabdian masyarakat. Tujuan pengabdian masyarakat ini adalah memberikan pengetahuan dan keterampilan kepada generasi muda khususnya remaja masjid agar siap menghadapi tantangan dunia kerja di masa depan. Metode pengabdian berupa pelatihan dan pendampingan kepada para remaja Masjid PC LDII Kecamatan Gunung Anyar Surabaya. Pelatihan berlangsung secara tatap muka di ruang aula PC LDII Surabaya, dilanjutkan praktek maintenance AC di halaman masjid. Setelah menyelesaikan kegiatan ini diharapkan peserta mempunyai keterampilan dasar di bidang perawatan AC Split, khususnya mampu melakukan pengecekan berkala pada pipa-pipa terhadap kebocoran pada komponen-komponen AC, baik dari segi mekanik maupun kelistrikannya , juga dapat melakukan pemeliharaan secara terjadwal.

Abstract

Efficient battery thermal management systems (BTMS) are essential for ensuring the safety and performance of lithium-ion batteries in electric vehicles. This study numerically investigates the influence of serpentine channel curvature on the thermal and hydraulic characteristics of a liquid-cooled prismatic battery module. Four channel designs were evaluated: a base case and three serpentine configurations with curvature values of 0.075 mm⁻¹, 0.1 mm⁻¹, and 0.15 mm⁻¹. Simulations were conducted under steady-state and transient conditions with discharge rates of 0.5C–2C and mass flow rates of 2.41 × 10⁻³ – 3.61 × 10⁻² kg/s. The results show that higher curvature and mass flow rates reduce maximum battery temperature and improve temperature uniformity, but at the expense of increased pressure drop and pumping power. At 3.61 × 10⁻² kg/s, the base-case channel exhibited a 28% increase in pressure drop compared to 2.41 × 10⁻² kg/s, while the 0.15 mm⁻¹ channel recorded up to a 60% rise under the same condition. Transient analysis revealed that curved channels enhanced heat dissipation, achieving up to 8.56% higher cooling performance than the base case. These findings highlight the trade-off between thermal improvement and hydraulic penalty, providing valuable guidance for optimizing liquid-cooled BTMS in electric vehicle applications.
