Abstract

Penelitian ini bertujuan untuk merancang dan membuat inkubator penetas telur penyu (Chelonioidea) semi otomatis untuk penentuan jenis kelamin penyu. Inkubator ini dilengkapi dengan mikrokontroler Arduino Uno, sensor suhu Thermocouple type-K, dan sensor kelembaban tanah YL-69. Sistem ini dikembangkan untuk mengatur suhu dan kelembaban dari media inkubasi guna mendukung keberhasilan penetasan serta penentuan jenis kelamin penyu. Proses inkubasi dilakukan pada dua ruang inkubasi dengan kondisi berbeda. Ruang inkubasi betina pada suhu 30°C dan kelembaban 60%, serta ruang inkubasi jantan pada suhu 26°C dan kelembaban 70%. Hasil pengujian menunjukkan bahwa sistem mampu menjaga kondisi suhu dan kelembaban sesuai parameter yang ditetapkan. Dari 40 butir telur yang diinkubasi dalam ruang inkubasi betina, berhasil menetas 23 ekor tukik betina dengan persentase 57,5%. Sedangkan dari 40 butir telur yang diinkubasi dalam ruang inkubasi jantan, menetas 18 ekor tukik Jantan dengan persentase 45%. Meskipun keberhasilan penetasan masih tergolong rendah, sistem inkubator semi otomatis ini telah berjalan dengan baik dalam mendukung proses penetasan dan pengondisian jenis kelamin pada penyu

Abstract

The advancement of composite material technology has significantly contributed to enhancing aircraft structural performance, komponen icularly in terms of weight efficiency and mechanical resistance. This study aims to analyze the influence of fiber orientation on the static response of a composite structure applied to the fairing flap arms component of the NC-212 aircraft. The analysis was conducted through simulation using ANSYS Workbench 2025 based on the Finite Element Method (FEM). The material used is glass fiber fabric/epoxy resin type 181 with various fiber orientation configurations, including (0°, 0°, 0°, 0°), (90°, 90°, 90°, 90°), (45°, -45°, 45°, -45°), (0°, -45°, 45°, 0°), (0°, 90°, 90°, 0°), and (90°, -45°, 45°, 90°). The results indicate that the fiber orientation of (45°, -45°, 45°, -45°) produces the highest Total deformasiof 0.091405 mm and the highest Von Mises stress of 89.132 MPa, along with the highest safety factor of 4.4791. Conversely, the (0°, -45°, 45°, 0°) orientation shows the lowest deformation at 0.07997 mm. These findings emphasize that fiber orientation significantly affects the mechanical behavior of composite structures. Diagonal fiber configurations tend to result in higher deformation and stress levels compared to unidirectional or perpendicular orientations.

Abstract

Misalignment and rotor unbalance are common faults in rotating machinery that can cause excessive vibration, uneven wear, and reduced machine performance. Motor current measurement provides a potentially low-cost alternative or complementary approach to vibration-based condition monitoring. This study investigates the relationship between vibration and motor current under normal, parallel misalignment, angular misalignment, and rotor unbalance conditions in an induction motor. Experiments were conducted at rotational speeds from 1800 to 2400 rpm under normal operating conditions, with parallel misalignment of 1 and 2 mm, angular misalignment of 1° and 2°, and rotor unbalance masses of 14.7, 18.1, and 21.5 g. Vibration and motor current signals were measured and compared to identify characteristic changes associated with each fault condition. The results showed that motor current increased by more than 10% relative to the normal operating current under misalignment conditions, whereas rotor unbalance was associated with a current reduction of more than 4% relative to the normal condition. These results indicate a measurable relationship between vibration and motor current and demonstrate the potential of motor current as a simple and cost-effective parameter for early fault identification.
