"ABSTRAKProses produksi, penanganan, dan penyimpanan berbagai combustible dust di Powder Plant Frisian Flag Indonesia menimbulkan risiko terjadinya dust explosion. Penelitian ini bertujuan untuk mengklasifikasi hazardous area dan menganalisis equipment yang sesuai dengan standar ATEX dan IECEx.Data berupa data primer dan data sekunder. Hasil klasifikasi hazardous area adalah zona 20, 21, dan 22 berdasarkan kemungkinan terbentuknya dust cloud. Hasil analisis equipment berupa ketentuan tentang approval marking, klasifikasi equipment, metode proteksi equipment terhadap ledakan, equipment protection level, dan suhu permukaan maksimum equipment yang diijinkan. Keberadaancombustible dustdan belum dipasangnya equipment yang sesuai untukpenggunaan di explosive atmosphere merupakan suatu kondisi yang sangat berbahaya. Untuk itu perusahaan harus menginstal equipment yang sesuai agar tidak menjadi sumber ignisi sehingga dapat mencegah terjadinya dust explosion.

ABSTRACTThe production process, handling, and storage of combustible dusts in the Powder Plant Frisian Flag Indonesia cause risk of dust explosion. This study aims to classify hazardous area and analyze equipment comply with ATEXand IECEx standards. Data in the form of primary and secondary data. Area classified for explosive dust atmosphere are divided into zones 20, 21, and 22, based up on the possibility of the occurance of dust cloud. The results of the analysis equipment isprovisions about approval marking, equipment classification, method of explosion protection, equipment protection level, and maximum permissible surface temperature. The existence of combustible dust and installation of equipment which is not suitable for use in explosive atmosphere are very dangerous condition. Therefore, the company must install the appropriate equipment so not to become source of ignition which can prevent the occurrence of dust explosion."

"Penelitian ini bertujuan untuk mengevaluasi penginstalan equipments yang tahan terhadap atmosfer eksplosif gas yang diinstal di PT. Pertamina Depot LPG Tanjung Priok dengan menganalisis hazardous area dan name plate equipments. Peneliti ingin melihat apakah equipments tersebut berisiko jadi sumber ignisi atau tidak di area yang mengandung gas flammable berupa propana dan butana. Sebagian besar equipments di PT. Pertamina Depot LPG Tanjung Priok belum memenuhi standar ATEX (Atmosphere Explosive) 94/9/EC, NFPA (National Fire Protection Association) 497, dan IEC (International Electrotechnical Commissions) dalam hal penginstalan equipments di zona yang sesuai. Penentuan zona sebagai bentuk dari hazardous area classification dilakukan dengan melihat radius ledakan dari hasil BREEZE Incident Analyst dan standar mengenai atmosfer eksplosif menurut ATEX 94/9/EC.

The purpose of this research is to evaluate the explosion-proof equipments installed in explosive atmosphere gas at PT. Pertamina Depot LPG Tanjung Priok by analyzing the hazardous area and equipments’ name plate. Whether those can be the ignition source or not when they are installed in an area full of gas flammable such as propane and butane. Most of the equipments do not comply to the standard used, which are ATEX (Atmosphere Explosive) 94/9/EC, NFPA (National Fire Protection Association) 497, and IEC (International Electrotechnical Commissions). Area zoning, that is categorized as hazardous area classification, is considered by explosion radius with BREEZE Incident Analyst and atmosphere explosive standard from ATEX 94/9/EC."
