Abstract

Reinforced concrete is a crucial element in infrastructure. However, it is unfortunate that the issue of corrosion in reinforced concrete structures has a significant impact and requires detailed consideration. Since the 1980s, research on corrosion-related problems has been initiated, one of which involves the SACP (Sacrificial Anode Cathodic Protection) approach using Zn sacrificial anodes. The purpose of this method is to control the corrosion rate in reinforced concrete. Environmental factors, such as the composition of solutions, play a role in influencing the resulting corrosion rate. Therefore, research is conducted by applying different solutions, namely 4% and 5% NaCl solutions, as well as Freshwater. This aims to compare the effects of these solutions on the measured corrosion rate using Zn anodes. The test results over a 4-week period indicate that the 5% NaCl solution exhibits a very high corrosion rate, as evidenced by the corrosion potential value of -790.3 mV. Conversely, the freshwater solution demonstrates a lower corrosion rate, with a corrosion potential value of -225.6 mV and a corrosion risk of only around 10%. This research provides a deeper understanding of the impact of solutions on the corrosion rate in reinforced concrete and offers a more scientific and contemporary perspective in line with current developments.

Abstract

Tujuan dari pengabdian masyarakat ini adalah untuk memberdayakan petani pinang dengan tujuan mempercepat proses pengupasan pinang dan meningkatkan kinerja petani. Kegiatan pengabdian ini dilaksanakan di Gampong Tualang Dalam, Kecamatan Serbajadi, Kabupaten Aceh Timur, Provinsi Aceh. Salah satu permasalahan yang dihadapi oleh petani pinang adalah proses pengupasan buah pinang yang belum efisien dan masih menggunakan alat-alat sederhana seperti pisau. Oleh karena itu, tujuan dari kegiatan pengabdian ini adalah merancang dan membuat alat pengupas/pembelah buah pinang dengan menggunakan metode mekanis. Metode kegiatan pengabdian ini terdiri dari tahap persiapan, pelaksanaan, evaluasi, dan pemantauan. Kegiatan pengabdian ini melibatkan mahasiswa dan dosen, serta melibatkan kelompok mitra petani yang tergabung dalam kelompok tani pinang. Proses pembuatan alat mekanis ini dimulai dengan tahap perancangan, diikuti oleh pembuatan alat secara langsung yang melibatkan petani di desa tersebut. Selanjutnya, petani akan diajari cara menggunakan alat pengupas buah pinang ini. Alat ini digunakan dengan cara menekan buah pinang hingga terbelah menjadi dua. Setelah dibelah, buah pinang ditempatkan dalam wadah untuk diambil buah pinangnya. Hasil dari kegiatan pengabdian ini menunjukkan bahwa mitra petani pinang telah memperoleh pengetahuan tentang pembuatan dan penggunaan alat pengupas buah pinang, serta berhasil mengoperasikan alat tersebut. Pengabdian ini juga berhasil meningkatkan produktivitas kerja petani. Hasil pemantauan menunjukkan bahwa masyarakat puas dengan alat pengupas dan pembelah buah pinang ini karena mampu mempercepat kerja petani. Namun, hasil evaluasi menunjukkan perlunya pengembangan ulang untuk membuat mesin otomatis tanpa bantuan tenaga manusia.

Abstract

Renewable energy utilization has become a primary focus in addressing the negative impacts of fossil fuel usage for electricity needs. One proposed solution is using water flow energy through a Pelton turbine. However, traditional materials used in Pelton turbines, especially metals, have disadvantages such as high inertia and susceptibility to corrosion. In this study, we replaced the Pelton turbine's material with fiberglass composite, which offers lower inertia and better corrosion resistance. This study aims to evaluate the performance of the Pelton turbine using fiberglass composite material. Tests were conducted by connecting the turbine to a generator and installing three adjustable nozzles, divided into seven sections based on the number of nozzles opened. Voltage, current, and electric power were measured using a power meter. The results show that with a load consisting of LED light bulbs, the section with one nozzle open (Section 2) achieved the best power output of 1.11 watts, while the section with two nozzles open (Section 6) achieved the best power output of 1.66 watts. Without load, the highest voltage occurred in Section 2 with one nozzle open at 30.9 volts, while the highest power was recorded in Section 4 with two nozzles open at 31.26 volts

Abstract

Artificial Intelligence (AI) technology is a breakthrough in the field of educational technology to facilitate learning. The wise and controlled use of technology can trigger the acceleration of education. The emergence of artificial intelligence technology can also instill an independent nature in students. Teachers are not burdened with such a dominant role, however, their duties are specific in the scope of providing enlightenment with substantial keywords. The basis of every use of technology for teachers is to continue to prioritize the essence of teaching, namely managing the morals and behavior of students. Students developing their emotional intelligence can take advantage of AI technology by sorting out the good things from the uses of AI so that educational technology can help them control and monitor their own learning, enabling them to live and work well in the future.

Abstract

The distortion in the shape of the weld specimen is influenced by the uneven heat distribution during the welding process. There is also distortion in the welding modeling performed on the bracket joint. The modeling scenario of the bracket joint forms the basis for measuring the distortion results. Therefore, when we model the bracket joint, we obtain varying distortion results. There are three lines to observe the distortion effects. Lines a, b, and c are located on the X and Y axes (center), while line c is on the X and Y axes (+). Line a is on the X and Y axes (-). The test specimen that has been modeled is the result of numerical modeling, which is then used to calculate the magnitude of the distortion on the longitudinally stiffened plate test specimen. For the numerical modeling of the bracket joint, the result of scenario 1 is distortion. Meanwhile, the distortion results of the bracket joint modeling in scenarios 1 and 2 show that the distortion value obtained in scenario 2 is higher than that obtained in scenario 1. This is influenced by the order of welding lines used in the bracket joint modeling.
