Abstract

Fly ash and sandblasting slag widely used as concrete’s builder because it contains quite high silica (SiO2) approximately 58,20% and 98,97%. Fly ash and sandblasting slag can increase concrete power pressure and contains characteristic like cement. Method of concrete making and technical feasibility test on this research use SNI standar (SNI 03-2834-2000). Environmental feasibility test use Toxicity Characteristic Leaching Procedur (TCLP) according PP No. 101 tahun 2014. The results of this research show that the use of  sandblasting slag can increase concrete power pressure at age of immersion 28 days. Concrete power pressure with 5%; 10%; 15%; and 20% sandblasting slag are 16,32 MPa; 17,81 MPa; 18,89 MPa; and 15,24 MPa. The use of sandblasting slag and fly ash can increase concrete power pressure at age of immersion 28 days. Concrete power pressure with 5% sandblasting slag and 30% fly ash; 10% sandblasting and 25% fly ash, 15% sandblasting and 20% fly ash, and  20% sandblasting and 15% fly ash are 18,53 Mpa, 16,08 MPa, 17,20 Mpa, and 15,91 MPa.  Based on the TCLP test, the concentration of heavy metal substances in 10% SBE are below the standard. Thus, it is  scientifically proven to conclude that concrete with 10% and 15% sandblasting slag and 5% sandblasting slag and 30% fly ash; 15% sandblasting and 20% fly ash are technically proper and safe for the environment.

Abstract

Palm oil refinery factory has solid waste by product  called Spent Bleaching Earth (SBE). SBE consists of some chemical compounds and one of them  is SiO2 up to 83,05%. SiO2 or silica fume can cause silicosis if it is exposed to the atmosphere and frequently inhaled by the workers.  On the other hand,  SiO2  is one of the material  composition of Portland cement. Thus, it is necessary to conduct a research about the utilization of SBE. as a concrete mixture. SBE is utilized as fine aggregate substitution by the composition of 0%, 10%, 20%, 30%, and 40% of the total amount of fine aggregate. The conducted tests are fineness modulus calculation, compressive strength, setting time, and TCLP. The method used for mix  design is SNI 03-2834-2000 with f’c 28,5 MPa and slump 12 ± 2 cm. This research  shows  that concretes with SBE substitution which achieve the planned compressive strength are 10% SBE with 34,16 MPa and 20% SBE with 29,06 MPa. Based on the TCLP test, the concentration of heavy metal substances in 10% SBE are below the standard. Thus, it is  scientifically proven to conclude that concrete with 10% SBE is technically proper and safe for the environment.

Abstract

Industri plastik memiliki karyawan sebanyak 927 orang yang menempati lahan 12.062 m2. Jam operasional pada industri plastik untuk unit produksi adalah 24 jam non stop. Dengan jumlah dan jadwal tersebut mengkibatkan kepadatan pekerja yang memiliki risiko untuk mengakibatkan kecelakaan. Perusahaan plastik ini memiliki riwayat kecelakaan kerja. Pada perusahaan ini pernah terjadi kebakaran pada unit ABM pada bulan September tahun 2018 dan divisi bengkel pada Mei tahun 2014. Ant Colony Optimization (ACO) sangat cocok menentukan jalur evakuasi dalam penanganan bencana karena algoritma ini melakukan pembaruan pada feromon yang dapat menghasilkan simulasi dengan solusi lebih optimal karena memiliki laju konvergensi yang cepat, sehingga ACO akan digunakan dalam menentukan Jalur evakuasi terpendek pada industri plastik. Pada penelitian ini digunakan feromon awal sebesar 0,0098. Hasil penentuan parameter yang akan digunakan, meliputi number of iterations yaitu 500, number of ant sebesar 100, nilai Alpha sebesar 1 serta Beta sebesar 5 dan evaporation rate sebesar 0.5. Dari hasil optimasi cost yang paling rendah adalah cost 2 sehingga didapatkan rute evakuasi untuk ruang Circullar Loom menuju Koridor 3 dilanjutkan keluar melalui pintu exit 4 sehingga menuju Titik kumpul 1. Semakin tinggi cost yang dihasilkan maka akan mengakibatkan rute yang dilewati menajadi jauh sehingga meningkatkan waktu evakuasi.

Abstract

Melting of metals generally used the energy source of natural gas which is flowed through a pipeline at high pressure. Production activities in companies that use these gases have high potential hazards because they can cause fires or explosions if not managed properly. This study aims to analyzed natural gas dispersion in the event of gas pipeline leak, determine assembly point and evacuation route map plan for workers in the event of emergency condition. Natural gas dispersion was simulated using Computational Fluid Dynamic Ansys Fluent. Results of simulation showed distribution concentration of natural gas indoors at leakage almost uniform with concentration between 5%-13,17%. At that concentration the mixture of air and natural gas has the potential to explode because it is in the range of natural gas flammability. The maximum natural gas concentration of 13.17% at a height of 12 m above the leak hole. Generated two points Assembly point based on the calculation of blast radius with total area of 58,500 cm2 and can accommodate as many as 65 workers.Keywords :CFD Simulation, Natural Gas Dispersion, Assembly point, Evacuation Rute
