Abstract

Penelitian ini bertujaan untuk mengetahui kendala yang dihadapi oleh orang tua selama mendampingi anak belajar dari rumah pada masa pandemi Covid-19. Metode yang digunakan dalam penelitian ini adalah kualitataif deskritif melalui wawancara pada 10 orang tua dengan anak yang sedang bersekolah di PAUD dan SD. Hasil penelitian ini menunjukkan bahwa secara keseluruhan orang tua dalam mendampingi anak belajar di rumah pada masa pandemi Covid- 19 adalah kurangnya pemahaman materi oleh orang tua, kesulitan orang tua dalam menumbuhkan minat belajar anak, orang tua tidak memiliki cukup waktu untuk mendampingi anak karena harus bekerja, orang tua tidak sabar dalam mendampingi anak saat belajar dirumah, kesulitan orang tua yang tidak memiliki gadget, dan kendala terkait jangkauan layanan internet. Penelitian ini diharapkan mampu menggali kendala- kendala orang tua dalam mendampingi anak ketika belajar dirumah sehingga penelitian ini mampu berkontribusi terhadap penelitian selanjutnya dalam menggali solusi untuk masalah- masalah tersebut.

Abstract

The global energy crisis and continued reliance on fossil fuels highlight the urgent need for sustainable alternatives. Dimethyl ether (DME) has emerged as a promising low carbon fuel owing to its clean combustion properties and versatility as an LPG substitute, diesel replacement, and chemical feedstock. This study focuses on optimizing the design of DME production from syngas derived methanol, with particular emphasis on conversion efficiency and thermal management. Base case simulations revealed that higher methanol dehydration conversion elevated reactor temperatures by nearly 100 °C, thereby disrupting equilibrium and hindering effective separation. To address these challenges, a modified process integrating cooling, heating, and distillation units was developed, achieving an 80% conversion and a DME yield of 97.6%, while simultaneously reducing excessive cooling requirements. These findings demonstrate that improved thermal control and separation strategies can significantly enhance both energy efficiency and environmental performance, reinforcing DME’s potential role in the transition toward cleaner energy systems.
