Abstract

The filtration is the final stage of industrial gas wastewater treatment for clean water generation. Filtration is an operation of separating solid and liquid materials by filter medium. In filtration process the driving force such as pressure difference by gravitation or rotary power cause the feed to flow. The process parameters in the filtration process need to be monitored and controlled because deviation or abnormality of the process parameters will cause operating failures. This condition requires a more in-depth identification so that the risks of operating failures can be minimized. HAZOPs is a method to identify hazard that caused by deviation of parameters using guide words. Steps of the research consisted of early survey, literature study, and filling the HAZOPs worksheet such as determine study node, deviation, parameter, guideword, risk evaluation, and risk control. The results of the study show that there were four potential deviations from three parameters which were flow, pressure, and temperature. Risk values analysed were medium and low. Recommendation of the system are adding alarm, valve, changing filter regularly, and scheduling the routine maintenance.

Abstract

Penggunaan pengkondisi udara jenis split di Indonesia mengalami kenaikan yang cukup signifikan. Hal ini mendorong naiknya kebutuhan akan teknisi pengkondisi udara yang berkompeten dalam melakukan perawatan dan perbaikan. Pelatihan perawatan dan pemeliharaan pengkondisi udara pada siswa SMK merupakan program yang penting untuk meningkatkan kualitas sumber daya manusia di bidang teknik refrigerasi dan tata udara. kegiatan pelatihan dilaksanakan dalam program pengabdian yang difokuskan pada dua kegiatan utama yakni pendalaman materi yang disampaikan oleh Tim Pengabdi dan peningkatan softskill melalui pelatihan perawatan dan perbaikan pengkondisi udara. Para peserta mendapatkan soal pretest dan post test untuk mengetahui ketercapaian kegiatan. Hasilnya didapatkan kenaikan sebesar 95%, dari hasil post test. Hal ini membuktikan bahwa tingkat pemahaman para Siswa setelah diberikan pelatihan mengalami peningkatan.
