"Karbon aktif adalah suatu karbon yang memiliki konfigurasi atom karbonnya terbebas dari ikatan dengan unsur lain dan porinya dibersihkan dari senyawa lain, sehingga permukaan serta pusat aktifnya menjadi luas, dan daya adsorpsinya meningkat.
Dalam penelitian ini, dilakukan pembuatan arang aktif dari tempurung kelapa sawit untuk menurunkan konsentrasi gas CO dan menjernihkan asap kebakaran. Proses aktivasi dilakukan secara kimia dan fisika. Tahapan pembuatan karbon aktif meliputi karbonisasi, aktivasi kimia dan fisika.
Karbonisasi karbon aktif dilakukan pada suhu 400ºC dilanjutkan dengan aktivasi kimia dengan bahan pengaktif KOH dengan konsentrasi 75%. Aktivasi fisika dilakukan dengan mengalirkan gas N2 selama 1 jam pada suhu 850 ºC dan dilanjutkan dengan mengaliri gas CO2 selama 1 jam pada suhu 850ºC.
Penelitian ini menghasilkan karbon aktif yang memenuhi Standar Nasional Indonesia yang memiliki luas permukaan sebesar 1295 m2/gram dan juga dapat diaplikasikan untuk pemurnian gas polutan pada unit purifikasi asap dengan persen adsorpsisebesar 15,7%.

Activated carbon is carbon which has a configuration of carbon atoms free from bond with other elements and their pores are cleared of other compounds, so that the surface as well as its active center became widespread, and the adsorption increased.
This research performed the manufacture of activated carbon made from oil palm shell to reduce the concentration of CO gas and clear the fire smoke. The activation process is done chemically and physically. Stages of manufacture of activated carbon include carbonization, chemical and physics activation.
The carbonization of activated carbon is carried out at 400ºC, followed by chemical activation with KOH activator material of 75% concentration. Physical activation is done by flowing N2 gas for 1 hour at 850ºC and followed by flowing CO2 gas for 1 hour at 850 º C.

"Penelitian ini dilakukan di gedung parkir 3 Mal Kelapa Gading untuk mengetahui perbedaan nilai konsentrasi karbon monoksida (CO) pada tempat parkir tertutup, gedung parkir, dan tempat parkir terbuka. Gedung parkir 3 memiliki 8 lantai, dengan 2 lantai adalah berupa parkir bawah tanah (basement) dan 6 lantai lainnya adalah gedung parkir di atas tanah. Lokasi parkir basement yang berada di ruangan tertutup membuat pihak pengelola harus bisa memastikan bagaimana kondisi sirkulasi udara di ruangan tersebut dapat terjaga. Karbon monoksida merupakan polutan yang berbahaya karena sifatnya yang tidak berbau, tidak berasa dan tidak berwarna sehingga tidak dapat terdeteksi secara fisik.
Penelitian yang dilakukan hari Senin dan Jumat ini menunjukkan bahwa konsentrasi maksimum CO terjadi di titik A 3 (ruang tunggu supir), yaitu sebesar 19 ppm pada hari Senin siang. Konsentrasi minimum CO adalah 0 ppm yang terjadi pada basement 2 (titik B 1 dan B 2), lantai P 3 ( titik D 1), dan parkir luar (titik E 2) di hari Jumat pagi dan siang, titik lantai P 1 (titik C 1), D 2, dan E 1 di hari Jumat pagi. Pada pengukuran hari Senin, seluruh nilai minimum CO sebesar 0 ppm terjadi di seluruh titik kecuali di titik A 3 pada siang hari, yakni sebesar 17 ppm. Berdasarkan hasil uji-t, jumlah kendaraan berpengaruh terhadap nilai konsentrasi CO di udara ambien. Berdasarkan uji ANOVA, ada perbedaan nilai konsentrasi CO antara ketiga jenis tempat parkir tersebut.

This study took place at Gedung Parkir 3 Mal Kelapa Gading to know the differences of concentration value of carbon monoxide in basement parking, building parking, and field parking. Gedung Parkir 3 is a 8 stories building, with 2 floors are the basement parking, and the other 6 floors are upperground parking structure. The basement parking that located in a confined space makes the manager should be able to ascertain how the conditions of the air circulation in the room can be maintained. CO is a dangerous pollutant because its odorless, tasteless, and colorless, so it can't be physically detected.
Research conducted on Monday and Friday shows that the maximum concentration of CO accurs at point A3 (the driver's waiting room), amounting to 19 ppm on Monday afternoon. The minimum concentration of 0 ppm CO is occuring in basement 2 (point B1 and B2), p3 floor (point D), and outside parking (point E2) on friday morning and afternoon, the floor P1 (point C1), D2, and E1 on friday morning. On monday measurement, all minimum value of 0 ppm CO occurs at all points except at the point A3 in the afternoon, which amounted to 17 ppm. Based on the results of t- test, the concentration of CO in ambient air is affected by the amount of vehicles. Based on the ANOVA test, there are diffirences in the concentration of CO between the three types of parking spaces."

"Ruang lingkup dan Cara penelitian : Karbon monoksida, merupakan gas sangat beracun yang dapat dihasilkan oleh kompresor. Kompresor konvensional yang digunakan nelayan penyelam sebagai alat penghasil udara tekan untuk 'media pernafasan' dalam air, dapat memberikan dampak negatif jika digunakan dalam jangka waktu yang lama. Penelitian tentang dampak pemakaian kompresor untuk penyelaman belum pernah dilaporkan, khususnya di Indonesia.
Penelitian ini bertujuan untuk mengetahui gambaran rata-rata kadar CO dalam udara kompresor konvensional; prevalensi intoksikasi CO; hubungan antara pajanan CO udara kompresor terhadap peningkatan COHb; besarnya peranan faktor resiko terhadap gambaran hematologi (peningkatan COHb). Parameter gambaran hematologi yang digunakan dalam penelitian ini adalah COHb, Hemoglobin, Hematokrit dan Eritrosit.
Disain penelitian adalah dengan menggunakan pendekatan cross sectional terhadap 75 subyek. Pengumpulan data dilakukan melalui wawancara terstruktur, pemeriksaan lisik, dan survey lingkungan kerja (laut).
Hasil, kesimpulan dan saran : Subyek terpajan dengan CO udara kompresor rata-rata 4,3 ppm, suatu pajanan yang masih tergolong dalam batas-batas aman untuk penyelaman dengan pemakaian kompresor atau SCUBA. Prevalensi intoksikasi CO dalam penelitian ini berada pada tingkat 'sub level CO intoxication'. Terdapat 9,3 % dari subyek menunjukkan gambaran hematologi bawah normal, dan 90,7 % menunjukkan gambaran normal. Efek hematologi yang merupakan peningkatan COHb mempunyai hubungan secara bermakna terhadap faktor resiko kondisi kompresor dengan O.R 15,58 (95 % C.I: 2,16 - 112,38 ), dan terhadap beban penyelaman dengan O.R 7,65 (95 % C.l : 1,30 - 44,93). Hubungan antara faktor resiko tersebut terhadap peningkatan COHb ternyata didukung pula oleh hasil analisis hubungannya terhadap gambaran hematologi secara bermakna pula.
Dengan hasil penelitian ini dapatlah disarankan agar nelayan penyelam selalu memperhatikan kesehatan dan keselamatan kerja dan berpedoman pada buku panduan, antara lain tentang hagaimana cara penggunaan dan perawatan kompresor, memperhatikan arah angin, dan beban penyelaman. Subyek perlu menyediakan waktu untuk aktivitas olahraga, melengkapi menu sehari-hari mereka dengan vitamin, dan sedapat-dapatnya dengan gizi yang haik.
Perlu dikembangkan kerjasama dengan instansi Departemen Kesehatan, Departemen Pertanian, gubernur KDKI Jakarta, RSAL Dr. Mintoharjo Jakarta, dan Program Studi Kesehatan dan Keselamatan Kerja Universitas Indonesia atau lembaga pendidikan yang terkait untuk membentuk suatu sistem atau organisasi yang dapat dilimpahkan wewenang serta tanggung jawabnya terhadap kesehatan nelayan penyelam, pembangunan chamber (HBO), riset dan pengembangan di bidang kedokteran kelautan di Indonesia umumnya dan di DKI khususnya.

Scope and methodology : Carbon monoxide is a highly toxic gas which could be produced by a compressor. Fishermen diver applied it as a compressed air producer, which can be used for sub aquatic breathing. Negative impact might be evoked if is used for a long period. Unfortunately, there has never been reported any study refer to this impact, nor any prevalence of carbon monoxide intoxication published concerning to application of compressor in diving, especially in Indonesia.
The objectives of study is to get a description of carbon monoxide level in air breathing of compressor, prevalence of carbon monoxide intoxication, and analysis of connection between car-bon monoxide exposure and hematologic figure or carboxyhemoglobin elevation. The parameters used in this study are carboxyhemoglobin level in blood, hemoglobin, hematocrit and red blood cell count.
The design of study was cross sectional. Data were collected by structured interview, physical examination, and field survey (offshore) over 75 subjects.
Result, conclusion and suggestion : The subjects were exposed to 4,3 ppm carbon monoxide level in average, within safe range in SCUBA diving or compressor's diving. Prevalence of carbon monoxide intoxication was sub level intoxication. Approximately, 9,3 % subjects had an undernormal figure, and 90,7 % showed normal hematologic figure. Hematological effect, which recorded as carboxyhemoglobin elevation exhibited a significant connection to the risk factors, namely compressor condition, with odds ratio 15,58 ( 95 % C.I: 2,16 - 112,38 ), and diving load with O.R 7,65 ( 95 % C.I: 1,30 - 44,93 ). This connection was supported by analysis of these risk factor with significant connection to hematologic figure.
Referring to this result, it might be suggested to the fishermen diver that they have to notice carefully their health and safety work. They are always guided by a diving manual in their duty, far instance, how to care and use the compressor, pay attention to the wind condition, and the load of diving. The subjects have to provide a time for physical exercise, vitamin supplement and good nutrient as much as they could.
A cooperation should be established among Health Department, Agriculture Department, local government ( Jakarta governor), Naval Hospital Dr. Mintoharjo Jakarta, University of Indonesia ( post graduate program of occupational health and safety) or another relevant institutes in developing a system or organization which take care of fishermen diver's health, chamber of LIBO, research and development of hyperbaric medicine in Indonesia, especially in Jakarta.
