Abstract

Udara sangat penting bagi kehidupan manusia, tanpa udara manusia tidak akan bisa hidup, oleh karena itu udara tidak boleh tercemar dengan gas-gas berbahaya yang dapat mengganggu kesehatan manusia. beberapa gas berbahaya ini terdapat didalam gas buang dari mesin yang digunakana untuk kehidupan sehari hari terutama di dalam kamar mesin yang dapat di klasifikasikan sebagai ruang tertutp berdasarkan pemerintah dan OSHA yang memiliki batasan tertentu sebelum membahayakan kesehatan dan keselamatan kru kapal. Oleh karena itu dibutuhkan alat untuk mendeteksi gas buang yang ada dengan alat yang berbentuk portable dan murah. Beberapa gas buang yang akan didieteksi dalam alat ini adalah CO dan CO2. Pendeteksiaan akan digunakan menggunakan sensor MQ 135 dan MQ 7 yang akan di monitoring menggunakan LCD screen yang akan dilakukan percobaan didalam ruang mesin. Percobaan dilakukan dengan melakukan eksperimen di skala laboratorium di ruang generator di teknik perkapalan, institut teknologi sepuluh nopember. Pada ruang generator memiliki hasil rata rata ppm untuk CO2 berupa 413.61 PPM dan CO berupa 8.31 PPM saat mesin dimatikan dan sedangkan data yang didapatkan pada mesin generator yang dinyalakan CO2 berupa 560.64 PPM sedangkan CO 9.15 yang masih jauh dari ambang batas yang telah di tentukan dari IMO maupun OSHA.Oleh dikarenkan itu hasil dari test tersebut memiliki kesimpulan bahwa alat dapat mendeteksi terdapat perbedaan saat mesin generator menyala dan tidak menyala.

Air is very important for human life, without air humans will not be able to live, therefore the air should not be polluted with harmful gases that can interfere with human health. some of these harmful gases are contained in the exhaust gas from the engine used for daily life, especially in the engine room which can be classified as a closed space based on government and OSHA which has certain restrictions before endangering the health and safety of the ship's crew. Therefore, a tool is needed to detect existing exhaust gases with a portable and inexpensive tool. Some of the exhaust gases that will be detected in this tool are CO and CO2. Detection will be used using MQ 135 and MQ 7 sensors which will be monitored using an LCD screen which will be tested in the engine room. The experiment was carried out by conducting experiments on a laboratory scale in the generator room at shipping engineering, ten nopember institute of technology. The generator room has an average ppm result for CO2 in the form of 413.61 PPM and CO in the form of 8.31 PPM when the engine is turned off and while the data obtained on the generator engine that is turned on CO2 is 560.64 PPM while CO is 9.15 which is still far from the threshold that has been determined from IMO and OSHA. Therefore, the results of the test have concluded that the tool can detect differences when the generator engine is on and not on and is still within the threshold of human health.
