Abstract

AbstrakPembangunan konstruksi di daerah rawan gempa harus memperhitungkan ketahanan gempa bumi pada konstruksi tersebut. Selain memperhitungkan ketahanan gempa, aspek korosi pada tulangan juga perlu diperhatikan. Hal ini diperlukan karena tulangan sangat rentan terhadap korosi. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penggunaan anoda korban terhadap potensial korosi pada tulangan beton busa berserat. Benda uji balok berdimensi 10x10x100 cm. Hasil yang diperoleh adalah beton busa berserat polypropylene SG 1,8 dengan anoda korban terhubung menunjukkan anoda korban belum bekerja untuk memproteksi tulangan terhadap korosi. Hal tersebut ditunjukkan oleh nilai potensial korosi pada beton busa yang belum mencapai nilai kriteria proteksi katodik, dimana nilai kriteria proteksi katodik adalah sebesar -850 mV sampai -1200 mV. Penelitian ini menunjukkan bahwa setelah 84 hari masa wet dry cycle dan pengambilan data, pengaruh anoda korban terhadap potensial korosi belum berhasil ditunjukkan.

Abstract

Corrosion is a very serious problem. It could not be prevented due to natural events which trigger corrosion itself. Many failures and losses caused by suboptimal early prevention of corrotion, such as the sudden collapse of buildings and infrastructure which incurring loss and casualties. One methode that is widely used to detect corrosion is the Half Cell Potential Mapping methode. However, there is shortage interpretation of data in the methods who need to be considered. Then, the software who could detect early failures caused by corrosion is developing. On of them is Boundary Element Invers Analysis (BEIA). BEIA has succeeded in detecting the location of corrosion in reinforced concrete with 5% error percentage. However, it is necessary to increas its ability. This research aims to find the effect of the amount of potensial value measurement data on BEIA ability to detect corrosion in reinforced concrete. BEIA developed by combining the application of Boundary Element Method (BEM) and Particle Swarm Optimization (PSO). BEM used to calculate potential values on concrete surface, while PSO evaluates the cost function for detecting corrosion in reinforcing steel in concrete. This research wa conducted on reinforced concrete 3-dimensional geometry, namely length, widht and height. In the middle of the concrete there is reinforcement which has corrosion. The parameter of the amount of potential value measurement data was varied in order to get better input in improving the performance of BEIA. That were 5,10, 15 and 20. The simulation showed that the used of the potential value measurement data of 20 had less error percentage value obtained at 650 cm x 50 cm geometry was 0.2 %. These proves that the larger potential value measurement data could improved BEIA performance.

Abstract

Korosi umumnya merugikan materi dan mengakibatkan korban jiwa apabila terjadi pada bangunan yang dijadikan sebagai pusat kegiatan manusia. Bangunan pertokoan Gampong Merduati merupakan salah satu bangunan terdampak korosi akibat air tsunami yang terjadi pada 2004 silam. Penelitian ini bertujuan untuk mengetahui pengaruh korosi baja tulangan terhadap kinerja struktur bangunan dengan melakukan assessment lapangan. Mutu beton diuji menggunakan hammer test dan tingkat korosi digunakan potential mapping. Struktur bangunan dibuat dua model yaitu model kondisi awal dan kondisi eksisting kemudian dihitung strukturnya dengan software SAP2000. Metode pembebanan digunakan metode push over kemudian dilakukan analisis apakah perlu dilakukan perkuatan struktur terhadap elemen beton bertulang. Hasil penelitian menunjukkan keseluruhan retak yang terjadi mempengaruhi kapasitas struktur bangunan tetapi beban yang bekerja masih dalam batas izin kapasitas struktur yang tersedia, korosi kolom K1 (30x30 cm) lantai I dan pada balok BL1 (30/50 cm) lantai II berada pada level korosi tinggi, hasil analisis pushover menunjukkan kapasitas dan kekakuan sruktur kondisi awal lebih besar daripada kondisi eksisting, level kinerja struktur berada pada level Immediate Occupancy, secara struktur kolom lantai I tidak memerlukan perkuatan dimana kolom masih mempunyai kekuatan tersedia lebih besar daripada kekuatan perlu tetapi secara korosi perlu diberikan epoxy resin agar korosi yang terjadi tidak semakin parah.

Abstract

This study aims to assess the corrosion risk level of Baitussalam Mosque in Tibang Village and Darul Makmur Mosque in Lambaro Skep, Banda Aceh. The corrosion potential value is measured using a Half-Cell Potential Meter and visualized using VisIt software. The Profometer 5+ instrument is used to locate the reinforcement and tendons in the reinforced concrete construction. The corrosion risk level is determined based on ASTM C876 standards. The corrosion mapping results show that the northern side of Baitussalam Mosque in Tibang Village, Banda Aceh, is in a severe corrosion risk level, and the southern side of Darul Makmur Mosque is in a low to high corrosion risk level. Therefore, Baitussalam Mosque and Darul Makmur Mosque require further assessment to prevent building failure caused by corrosion.

Abstract

Penelitian ini bertujuan untuk mengembangkan kemampuan Boundary Element Inverse Analysis (BEIA) dalam mendeteksi korosi lokal pada beton bertulang dengan variasi data potensial dalam mendeteksi 2 lokasi korosi. Pengembangan BEIA berbasis Boundary Element Method (BEM) dan Particle Swarm Optimization (PSO). BEM digunakan untuk menghitung nilai potensial pada permukaan beton. Kemudian PSO digunakan untuk mengevaluasi cost function untuk mendeteksi korosi pada baja tulangan yang berada di dalam beton. BEIA dijalankan dengan data nilai pengukuran potensial pada permukaan beton. Hasil simulasi dari BEIA menunjukkan posisi partikel berada pada lokasi yang ditentukan. Dari hasil simulasi BEIA dengan variasi jumlah data potensial dalam mendeteksi lokasi korosi pada beton bertulang dapat disimpulkan bahwa jumlah data pengukuran nilai potensial yang lebih besar dapat meningkatkan kemampuan BEIA dalam mendeteksi lokasi korosi pada beton bertulang. Hal ini membuktikan jumlah data pengukuran nilai potensial berpengaruh pada kinerja BEIA.Kata kunci—Deteksi korosi, BEM, PSO, BEIA, Beton Bertulang

Abstract

Corrosion is the primary cause of premature infrastructure damage, affecting everything from homes and public spaces to industrial facilities, including the rapidly expanding palm oil industry in Aceh, particularly along its eastern and northern coasts. This rapid growth necessitates careful consideration of environmental impacts, including pollution, which can also degrade air quality. Pollutants increase the susceptibility of steel-reinforced structures to atmospheric corrosion. This research, therefore, investigates atmospheric corrosion of structural steel at several palm oil processing plants: PTPN 1 Tanjung Seumantoh in Aceh Tamiang, PT Ensem Sawita and PT Anugerah Fajar Rejeki (AFR) in East Aceh, and PTPN 1 Cot Girek in North Aceh.This study measures the atmospheric corrosion rate of structural steel typically used in industrial and nearby residential settings. Five steel types were tested: strip, angular, cylindrical, commercial plate, and low-carbon steel. Following the American Standard Testing and Material-G50 (ASTM G50), the mass loss method was used to calculate corrosion rates. After six months of exposure, all five steel types exhibited corrosion rates below 0.7 mils per year (mpy). This result showed that the relative corrosion resistance of structural steel is on outstanding category (<1mpy).

Abstract

This study aims to explore the important role of weather parameters i.e. humidity, rainfall, temperature, and wind speed on the corrosion rate in the Medan City atmospheric environment. Three forms of material with low carbon steel type were prepared in this investigation. The exploration process was conducted for six months starting from June to December 2023, in the open area of the Engineering Faculty, Universitas Muhammadiyah Sumatera Utara. Corrosion rate assessment is carried out monthly using the weight loss method and climate parameter data is obtained from the Medan City Meteorology and Geophysics Agency (BMKG). The dimensions, initial preparation, data collection, post-test material preparation, and corrosion rate calculations refer to the ASTM G1 and G50 standards. Regression analysis and Pearson correlation explain the relationship between corrosion rate and climate parameters. The investigation showed that the corrosion rate fluctuated monthly from 0.1 to 0.5 mpy. By referring to corrosion resistance data on metal materials, it was found that the corrosion level was in the good resistance category "outstanding". Based on the regression analysis results, humidity, local temperature, and rainfall play an important role in the atmospheric corrosion rate in Medan City. The percentage of closeness between variables is ± 98% and the standard deviation is ± 0.0001. Further development is needed to determine other parameters that also play an important role in atmospheric corrosion rate and forming a random forest model for predicting future corrosion rates.

Abstract

Wild boars pose a significant threat to cassava farmers in the Jantho Baru area, Aceh Besar district, as they can reduce agricultural productivity. The region's location in hilly terrain near a protected forest makes this challenge unavoidable. An initial assessment with farmer groups (partners) identified the need for a monitoring and protection system to manage wild boar infestations in cassava farms. The partner's land, situated 42 km from the Faculty of Engineering, Universitas Syiah Kuala, spans 5 hectares in a hilly area adjacent to the protected forest.To address this issue, an IoT-based technology solution is proposed for monitoring and safeguarding cassava farms. This system includes video cameras that allow farmers to remotely monitor their land via smartphones. Additionally, security measures such as electric fences and speaker outputs, controlled through an Android-based mobile application, are implemented. The system is powered by renewable solar energy through the use of solar panels. The application of this technology is expected to reduce crop losses caused by wild boars, ultimately improving farm productivity.

Abstract

Organic plants are gaining serious attention as metal corrosion protection. As a non-toxic material, Syzygium cumini (SC) fruit extract contains antioxidant substances that can slow the corrosion rate. This research aimed to explore SC fruit extract as a green inhibitor of corrosion on AISI 1020 low carbon steel against exposure to 1 M HCl solution. SC fruit was extracted by the Soxhlet method and characterized using total flavonoids and tannins content. The inhibition systematics were analyzed using weight loss (WL), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS) methods. The results showed that the concentration of 600 mg/L had good corrosion inhibition effectiveness with efficiency reaching 72.91 (WL), 90.26 (PDP), and 75.15% (EIS). Surface characterization was investigated using scanning electron microscopy (SEM), Fourier transform infrared (FTIR), atomic force microscope (AFM), and X-ray diffraction (XRD) analyses. After the presence of inhibitors, corrosion products and damage to the steel were minimized compared to unprotected. This was based on the activity of inhibitor reaction to form a protective film. With the implementation of this material, SC fruit extract could be used as an environmentally friendly natural inhibitor.

Abstract

Abstract: Reinforced concrete foam is one alternative to replace conventional reinforced concrete on structural elements. This study aims to measure the The media immersion and variation of specific gravity (SG) is a variable of interest in this study. The specimen type used is Normal foamed concrete (BB) and pozzolan foamed concrete (BBP). The test specimens used were 8 x 8 x 50 cm, with single reinforcement 10 mm in it. Reinforced placement of the reinforcement so that the test specimen has a thickness of 4 cm concrete cover. The specimen was immersed in freshwater and artificial seawater in the form of a 3.5% sodium chloride solution. The measurements results using half-cell potential mapping (HCPM) technique described the highest corrosion risk location. At this location corrosion rate measurement performed using linear polarization resistance (LPR) method. The corrosion rate calculation result of normal foamed concrete SG 1,2, 1,4, 1,6 with NaCl 3.5% and fresh water immersion medium ranged from 0,621 mpy up to 0,854 mpy and 0,194 mpy up to 0,304 mpy. The corrosion rate value of pozzolan foamed concrete SG 1,2, 1,4,1,6 with 3.5% NaCl and fresh water immersion media ranges from 0,429 mpy up to 0,545 mpy and 0,072 mpy up to 0,120 mpy. The larger SG value of the foamed concrete specimen used, the less corrosion rate occurs. Corrosion behavior of pozzolan foamed concrete is better than normal foam concrete, this phenomenon occurs due to the effect of adding 10% pozzolan which causes better foamed concrete permeability, so that the resistance of concrete against corrosion increased. In general the corrosion rate of pozzolan foamed concrete in the freshwater environment and corrosive environment (artificial seawaters of NaCl 3.5%) is smaller than the corrosion rate of normal foamed concrete.Abstrak: Beton busa bertulang merupakan salah satu alternatif untuk menggantikan beton bertulang konvensional pada elemen struktural. Penelitian ini bertujuan untuk mengukur laju korosi pada beton busa bertulang. Media rendaman dan variasi berat jenis (SG) merupakan variabel yang ditinjau dalam penelitian ini. Jenis benda uji yang digunakan berupa beton busa normal (BB) dan beton busa pozzolan (BBP). Benda uji yang digunakan berbentuk balok 8 x 8 x 50 cm, dengan tulangan tunggal 10 mm didalamnya. Dilakukan penempatan tulangan sehingga benda uji memiliki ketebalan selimut 4 cm. Benda uji direndam menggunakan air tawar dan air laut buatan berupa larutan Natrium Clorida 3,5%. Hasil pengukuran menggunakan teknik half-cell potential mapping (HCPM) menggambarkan lokasi yang memiliki resiko tertinggi terkorosi. Pada lokasi ini dilakukan pengukuran laju korosi dengan menggunakan metode linear polarization resistance (LPR). Hasil perhitungan laju korosi pada beton busa normal SG 1,2 sampai 1,6 dengan media rendaman larutan NaCl 3,5% dan air tawar berkisar antara 0,621 mpy sampai dengan 0,854 mpy dan 0,194 mpy sampai dengan 0,304 mpy. Nilai laju korosi pada beton busa pozzolan SG 1,2, 1,4, 1,6 dengan media rendaman NaCl 3,5% dan air tawar berkisar antara 0,429 mpy sampai dengan 0,545 mpy dan 0,072 mpy sampai dengan 0,120 mpy. Semakin besar nilai SG benda uji beton busa yang digunakan, maka laju korosi yang terjadi semakin kecil. Perilaku korosi beton busa pozzolan lebih baik dari pada beton busa normal, fenomena ini terjadi akibat pengaruh penambahan 10% pozzolan yang menyebabkan permeabilitas beton busa semakin baik sehingga ketahan beton terhadap korosipun semakin meningkat. Secara umum laju korosi pada beton busa pozzolan dilingkungan air tawar dan lingkungan korosif (air laut buatan NaCl 3,5%) lebih kecil dibandingkan laju korosi beton busa normal.
