Abstract

Penelitian ini bertujuan mengkaji pengaruh fraksi massa serat dan variasi konsentrasi larutan NaOH terhadap sifat mekanik material komposit berbasis serat alami dan resin epoxy. Serat yang digunakan meliputi kulit jagung, sabut kelapa, dan serbuk kayu sengon, sedangkan resin yang digunakan adalah resin epoxy. Metode fabrikasi yang digunakan adalah hand lay-up dengan fraksi massa serat 20%, 25%, dan 30%, serta konsentrasi NaOH 5% dan 10% untuk proses alkalisasi serat. Enam spesimen (A1–B3) diuji sifat mekaniknya melalui uji tarik dan uji impak. Hasil menunjukkan bahwa spesimen B1 (NaOH 10%, fraksi serat 20%) memiliki kekuatan tarik tertinggi yaitu 34,684 MPa dan nilai regangan 1,33041. Modulus elastisitas tertinggi terdapat pada spesimen A1 sebesar 29,7274 MPa. Pada uji impak, spesimen A1 menunjukkan ketangguhan tertinggi dengan nilai 0,661 J/mm². Penelitian ini menunjukkan bahwa variasi fraksi massa serat dan perlakuan alkalisasi dapat mempengaruhi kekuatan dan ketangguhan komposit, menjadikannya potensial sebagai bahan alternatif spakbor motor yang ringan, kuat, dan ramah lingkungan.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan bentuk-bentuk interferensi bahasa Bajo Bugis dalam pembelajaran Bahasa Inggris, khususnya pada keterampilan membaca siswa kelas VII SMP Negeri Satu Atap 1 Keruak. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan teknik pengumpulan data berupa observasi, wawancara, dan dokumentasi. Hasil penelitian menunjukkan bahwa interferensi terjadi pada aspek fonologi, morfologi, sintaksis, dan semantik. Interferensi fonologi tampak pada pengucapan kata yang mengikuti pola bahasa ibu, sementara interferensi morfologi terlihat dari penambahan imbuhan lokal. Pada aspek sintaksis, siswa cenderung menggunakan urutan kata yang sesuai dengan struktur bahasa Bajo Bugis, sedangkan pada aspek semantik, siswa sering menerjemahkan secara literal yang menyebabkan kesalahan makna. Interferensi ini berdampak pada pemahaman teks bacaan siswa yang cenderung kurang akurat. Penelitian ini menegaskan pentingnya peran guru dalam merancang strategi pembelajaran yang lebih kontekstual dan kontrastif agar siswa mampu membedakan secara jelas antara sistem bahasa ibu dan bahasa Inggris yang dipelajari.

Abstract

The need for electricity is good for the industry, offices, and public and individuals are greatly increased. However, the increase in demand for electricity is not accompanied by the additional power supply. Based on these problems, chosen solar energy as an alternative energy to generate electric power. A tool that is used here is the solar cell because it can directly convert solar radiation into electrical energy (photovoltaic process). So that solar energy can be used at night, then during the day, the electrical energy generated is stored before a battery which is controlled by the regulator. Regulator output is directly connected to the inverter from the DC to AC. The test results of solar modules (photovoltaic) indicated that the results of the average power output reached 38.24 Watt, and the currents were 2.49 A.  This is because the photovoltaic follows the direction of movement of the sun and always located at the photovoltaic to remain facing the sun. Therefore, it will still be able to capture the radiant sun to the fullest.

Abstract

For the sake of the smooth process of cement production, it is necessary to maintain each component of the production. One of the tools that play an important role in the maintenance and production of cement is the Overhead Traveling Crane, which is a combination of a separate lifting mechanism with a frame to lift and move loads that can be hung freely or attached to the crane itself. The problems that arise in the Overhead Traveling Crane include the reverse direction of the motor rotation due to an error in the motor connection, the motor cannot start due to a disconnected power supply, the occurrence of bending (curving) on ​​the girder due to lifting operations that exceed the maximum capacity which can also accelerate service life. of the girder, wear on the wheel due to high workload during operation. Due to the need for very long use, periodic maintenance is needed so that it can be in normal condition for a long time. The main parts that support the overall weight of the crane are rails and wheels. This journal discusses the analysis of failures that occur due to contact between rails and wheels that occur in a cement factory. Failure analysis is done by testing the hardness of both the wheel and the rely which is considered to have failed or is no longer suitable for use. Then review the results of direct field observations with data from hardness tests and literature studies related to wheels and rails. after that it was concluded that the company considered for the procurement of rails and wheels. The conclusion obtained is that the hardness value on the rail is lower than on the wheel. Resulting in failure of the rail so that the rail must be replaced.

Abstract

One of the tests used to determine the mechanical properties of metals is the tensile test. The results obtained from the tensile test are crucial for engineering and product design as they provide data on the strength of materials. AISI 1045 carbon steel is an alloy steel composed of iron (Fe) and carbon (C), where iron is the base element and carbon is the main alloying element. Carbon steel is also used in the manufacturing of helical/coil springs (Mobil Alvanza 2020). Coil springs are widely used in the front suspension of modern light vehicles. A new approach to fatigue prediction based on a combination of FE simulation using ABAQUS is opposed in this study. In this research, the tensile test was performed using experimental and ABAQUS simulation methods. The experimental results showed a yield strength of 350.25 MPa and an ultimate tensile strength of 560.4 MPa, while the ABAQUS simulation results showed a yield strength of 356.05 MPa and an ultimate tensile strength of 560.39 MPa

Abstract

The distribution system of electrical power begins from generation and is transmitted to the load, namely consumers. In this distribution, it must be effective, efficient, and reliable. The amount of electrical power reaching the load is not the same as the amount of power generated due to voltage drop or power losses. This research aims to determine the magnitude of power losses in the medium-voltage distribution network located in Pasar Aceh. The research method employed is the analysis and simulation calculation method using ETAP 12.6 software. The study analyzes power losses due to load imbalance in the JTR distribution substation of Pasar Aceh. Based on the analysis results, the load imbalance in the Pasar Aceh substation has led to power losses. The power losses in the Pasar Aceh substation, specifically at the Side Transformer of Pasar Aceh, are 0.77% with a load imbalance of 16.33%. For the second transformer in the BNI 46 area, the power losses are 0.98% with a load imbalance of 30.33%, and for the transformer in the BLKG KOTTY area, the power losses are 1.17% with a load imbalance of 50.33%. Therefore, the larger the percentage of load imbalance in an electrical distribution network, the greater the resulting power losses.

Abstract

This experimental study examines the impact of speed variations on the 2.5 mm nozzle diameter in low-carbon steel laser cutting. The primary objective is to optimize the roundness of the cut by considering cutting speed factors. Through a series of experiments conducted on low-carbon steel plates measuring 200 mm x 200 mm, utilizing a 2.5 mm nozzle diameter with speed variations of 2, 3, and 4 m/minute, the research measures roundness quality using a digital caliper. Results indicate that cutting speed influences roundness quality, with the lowest deviation observed at a speed of 2 m/minute and the highest at 3 m/minute. The study also highlights that increased cutting speed and the use of a larger nozzle require higher gas pressure.
