Corrosion is metal loss due to interaction with the surrounding environment. The consequences of corrosion are so damaging that they can have an impact on human casualties. A report from NACE in 2002 has shown that corrosion losses in the United States was about 3.1% of Gross Domestic Product (GDP). This figure was expected to increase in 2016 to over 6.2% of GDP. Overall, the losses caused by corrosion have reached 3-4% of the GDP of the industrialized countries. The numbers are very large and therefore, corrosion control are very important to be implemented. In efforts to control corrosion, research in the area has been widely conducted. Experimental research has played a very important role. However, the development of simulations in the world of corrosion is also very promising. Corrosion simulations are developed based on numerical methods. The commonly used numerical method is the boundary element method (BEM). In subsequent developments, the optimization method has also been used in the case of inverse analysis such as corrosion detection. This paper presents briefly the development of corrosion simulation which has been performed by many researchers in efforts to solve various corrosion cases.

The objective of this research is to analyze the results of the topology optimization model Hip Stem Prosthesis in heel strike and flat foot conditions. The simulation is done using software based on finite element method ANSYS Release 18.0. Analysis of heel strike and flat foot conditions was carried out on the design of the artificial pelvic bone AML (Anatomical Modullary Locking) model. The ball head diameter used in this research was 38 mm and stem length was 140 mm. The analysis is done by optimizing the hip stem prosthesis step by step according to the condition when walking. Loading is given to the hip stem prosthesis during heel strike and flat foot with a time history of 0,01 seconds and 0,2 seconds starting from the initial position of heel strike and ending with the flat foot position. The simulation results show that the stress distribution is evenly distributed and the size of the volume of the design region varies.

The objective of this study is to study the influence of anode-cathode displacement to corrosion potential distribution of reinforced concrete cathodic protection system. Reinforced concrete speciments with a length of 1000 mm, width of 100 mm, and a height of 100 mm were used. Three variations of anode-cathode displacement for the specimens were 5 mm, 10 mm, and 20 mm. Specimens were immersed in a solution of NaCl 3.5 % and treated by wet-dry cycle. Profometer 5 + was used to find the location of reinforcement without damaging the surface of the concrete. Half-cell potential digital meters was used to measure the corrosion potential value of steel reinforcement. The corrosion potential measurements after 12 weeks of wet-dry cycle shows that the most negative corrosion potential was obtained for 10 mm anode-cathode displacement, i.e-391 mV. While for 5 mm and 20 mm anode-cathode displacements were -374 mV and -378 mV. Therefore, the anode-cathode displacements might affect the distribution of corrosion potential on reinforced concrete cathodic protection system.

The aeration process is a method to increase the dissolved oxygen levels in the water environment. In the pond area has a minimum requirement of dissolved oxygen content in the water so that fish can live and develop. The minimum value of dissolved oxygen in the pond area is 4 mg / l, but the higher the level of dissolved oxygen in the pond area, the better the results of the pond. Previous research conducted by Rizki was Analysis of the Potential of Wind Energy for Windmill Aerator Performance of ponds in Alue Kumba in East Aceh Regency, and the results of these studies showed that the wind energy in the Alue Kumba Village had the potential to operate windmill aerators. However, this study has not shown the results of the dissolved oxygen value of the windmill aerator system, therefore this study aims to obtain results and the area that can be reached by a diffuser. The method used is data collection of dissolved oxygen from the diffusser installation with a distance of 1.5 meters and data collection at 3 times, morning, afternoon and evening. Installation of windmill aerator in the morning produces dissolved oxygen value of 7.42 mg / l with a maximum distance of 18 meters, then in the afternoon the oxygen value of 6.23 mg / l with a maximum distance of 15 meters, and for the afternoon conditions the value of dissolved oxygen is 5.16 mg / l with a maximum distance of 16.5 meters. The dissolved oxygen value after the installation of the windmill aerator increased with an average increase of 1-2 mg / l at each measurement point with the highest dissolved oxygen highest value of 7.42 mg / l up from 5.52 mg / l with a maximum distance of 18 meters on the measurement morning. From the results of this study explain that this method can produce a good area of dispersed dissolved oxygen with an average distance of 16.5 meters with a minimum dissolved oxygen condition that is good for fish to develop in the area of the pond

This research simulates the galvanic effect on medium carbon steel from the result of heat treatment using the Boundary Element Method (BEM) -3D. BEM was developed with the assumption that the electrolyte surrounding the anode-cathode system no ions in or out, so that it can be modeled as Laplace domain. The potential value and the current density across the surface of the domain can be determined by solving the Laplace equation using the BEM. The Galvanic effects can be analyzed by using the potential data. To simulate the galvanic effect on medium carbon steel the result of heat treatment, two anode-cathode combination was set. The first combination is the annealing steel as the anode and the normalizing steel as the cathode. While the second combination is a hardening steel as the anode and the normalizing steel as the cathode. The conductivity value of the electrolyte for the galvanic effect simulation is 0.0541 Ω / m. The simulation results of the first combination showed the most negative anode potential value is -104.09 mV and the cathode potential value of -85.41 mV. While the simulation results from the second combination provides the most negative anode potential value are -220.27 mV and the cathode potential value are -85.41 mV. From the simulation can be seen that the potential difference between the first anode-cathode combinations are +18.69 mV and the second combination are +134.86. Thus, the simulation results show that the combination of annealing steel and normalizing steel produce galvanic effect is relatively small. While the combination of hardening steel and normalizing steel provide galvanic effect is relatively large.

AbstractNowadays, corrosion probem become one of the important problem for infrastructures over the world. Therefore, over the last decades, several corrosion reearch has been investigated. Several software have been developed to simulate corrosion that occurs on the reinforcing steel in concrete. The fundamental goal of the simulation is to predict the degree of corrosion that achieved. Many pioneering works allowed for the successful application of the boundary element method (BEM) to simulate the corrosion. This research aims to study the ability of Boundary Element Inverse Analysis (BEIA) in detecting corrosion that more than one location or known as Multi corrosion on the reinforcing steel in concrete. BEIA is a method that developed to detect corrosion in reinforced concrete. BEIA developed by combining the application of Boundary Element Method (BEM) and Multi-objective Particle Swarm Optimization (PSO). BEM used to calculate potential values on concrete surfaces. Furthermore, PSO is used to evaluate the cost function to detect corrosion on reinforcing steel inside concrete. To execute BEIA, it requires several input parameters include the results of meshing and potential data from the field. However, in this case, the field potential data used is the result of the calculation of BEM simulation with a mesh size of 4mm and assuming the location of corrosion is at X1 = 50 mm and X2 = 350 mm. The simulation results from BEIA show that the position of the particles at the 150th iteration is already at the specified location, at X1 = 50 mm and X2 = 350 mm, this proves that Multi-objective BEIA can simulate multi corrosion detection that occur on a concreted surface..

Kualitas air tambak menjadi menurun akibat penumpukan kotoran udang, aktivitas bakteri, ganggang, dan lain-lain, sementara penggantian air baru juga memiliki risiko yang tinggi dengan tingginya kemungkinan masuknya virus berbahaya ke dalam tambak. Salah satu cara untuk menjaga kualitas air tambak adalah dengan melakukan aerasi secara teratur. Ketersediaan listrik menjadi kendala untuk areal tambak udang di Desa Alue Kumba akibat belum terkoneksinya jaringan listrik PLN. Penelitian ini dilakukan untuk mengkaji efektivitas kincir angin sebagai solusi penyediaan oksigen terlarut pada tambak udang tradisional di Desa Alue Kumba serta dapat menjaga kualitas air selama pemeliharaan udang yang dapat berujung pada peningkatan produktivitas tambak. Perlakuan yang diterapkan merupakan kombinasi konstruksi kincir angin dan air tambak dengan sistem kecepatan angin oleh turbin savonius yang ditimbulkan untuk menggerakkan bagian kipas yang memunculkan tenaga pembangkit gelembung pada kolam tanah (tambak). Hasil kombinasi kincir yang dilakukan efektif dalam menghasilkan oksigen terlarut dalam tambak tradisional di Desa Alue Kumba Kecamatan Rantau Selamat Kabupaten Aceh Timur.

Korosi merupakan proses penurunan mutu logam akibat interaksi logam tersebut dengan lingkungannya. Kawasan Industri Medan (KIM) merupakan salah satu pusat perindustrian yang berada di kota Medan Sumatera Utara. Besarnya tingkat pembuangan hasil limbah industri mengakibatkan tingginya tingkat potensial terjadinya korosi atmosferik disekitar kawasan industri tersebut. Sehingga diperlukannya investigasi untuk melihat laju korosi atmosferik di KIM. Penelitian ini menceritakan investigasi laju korosi atmosferik baja karbon rendah profil segiempat di KIM. Spesimen uji dan proses pengukuran laju korosi mengikuti standard ASTM G-50 dan ASTM G-1. Pengukuran laju korosi dilakukan selama enam bulan dengan metode pemaparan secara langsung di lima titik lokasi yaitu KIM 1, 2, 3, 4 dan 5. Hasil investigasi menggambarkan laju korosi rata-rata baja karbon rendah profil segiempat selama enam bulan sebesar 0,308 mpy. Laju korosi tertinggi terjadi di lokasi KIM 3 dan KIM 5 dengan laju korosi rata-rata sebesar 0,382 mpy dan 0,564 mpy. Sehingga dapat disimpulkan laju korosi baja karbon rendah profil segiempat di lingkungan Kawasan Industri Medan dalam kategori outstanding (< 1 mpy) dan sangat aman digunakan untuk kebutuhan konstruksi pada lokasi tersebut.
