Abstract

Kegiatan Pelatihan Dasar Pengoperasian Komputer Tingkat SMA dilaksanakan sebagai upaya untuk meningkatkan kemampuan literasi digital dan keterampilan teknologi dasar pada peserta didik. Di era digital saat ini, kemampuan mengoperasikan komputer serta menguasai aplikasi perkantoran seperti Microsoft Word, Microsoft Excel, dan Microsoft PowerPoint menjadi kompetensi penting yang harus dimiliki oleh siswa untuk mendukung proses pembelajaran maupun kesiapan menghadapi dunia kerja. Berdasarkan hasil observasi, diketahui bahwa sebagian siswa belum memperoleh pembelajaran komputer secara formal, sehingga masih memiliki keterbatasan dalam mengenal perangkat keras, perangkat lunak, serta sistem operasi dasar. Melalui pelatihan ini, siswa diberikan pembelajaran teori dan praktik langsung mengenai pengoperasian komputer dan penggunaan aplikasi Microsoft Office secara efektif. Hasil kegiatan menunjukkan meningkatnya pemahaman siswa terhadap dasar-dasar komputer, kemampuan mengoperasikan aplikasi Microsoft Office serta hasil praktik yang menunjukkan bahwa siswa mampu membuat dokumen, mengolah data sederhana dan menyusun presentasi secara mandiri maupun per kelompok. Dengan demikian, kegiatan pelatihan dasar komputer ini memberikan kontribusi nyata dalam membekali siswa dengan kemampuan teknologi informasi yang relevan, mendukung proses belajar mengajar, dan mempersiapkan mereka untuk menghadapi tantangan dunia digital masa kini dan mendatang.

Abstract

Heating, Ventilation, and Air-Conditioning (HVAC) systems contribute significantly to electricity consumption in tropical educational buildings due to continuous cooling demand. This study evaluates the influence of indoor temperature setpoints on cooling energy consumption and thermal comfort in two university classrooms equipped with split air-conditioning systems in Medan, Indonesia, using EnergyPlus simulations. Six temperature setpoints ranging from 20°C to 25°C were analyzed under identical operational and climatic conditions. Thermal comfort performance was assessed using the Predicted Mean Vote (PMV) method based on ASHRAE Standard 55. To verify the representativeness of the climatic input data, the outdoor dry-bulb temperature obtained from the EPW weather file was compared with observed outdoor temperature data collected on 30 May 2026, resulting in a relative error of 2.26%. The results show that increasing the setpoint temperature reduced annual cooling electricity consumption from 5,515 kWh to 3,607 kWh in Room J20.301 and from 5,284 kWh to 3,581 kWh in Room J20.302, corresponding to energy savings of 34.6% and 32.2%, respectively. However, thermal comfort performance decreased as the setpoint increased. At 25°C, PMV values reached 0.71 and 0.73, exceeding the ASHRAE comfort limit and reducing annual comfort compliance to below 1% in both rooms. The 23°C setpoint provided the most balanced performance, with annual energy consumption of 4,379 kWh and 4,292 kWh while maintaining PMV values within the acceptable comfort range at 0.35 and 0.32. Annual comfort compliance at this condition reached 87.6% and 96.1% for Rooms J20.301 and J20.302, respectively.
