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

The finned drive wheel technology is widely used for wet rice fields. Currently, finned drive wheels for peat fields have not been developed and still use traditional agricultural tools such as hoes and sickles, while the finned drive wheels for wet rice fields are not yet able to work optimally on peat rice fields. The driving wheel model and testing in peat rice fields were carried out in this research. Design and manufacturing were carried out by referring to previous research literature. This initial research was carried out in wet rice fields on open-close finned drive wheels and standard finned wheels, with the aim of measuring the comparative level of performance of the two wheel models. The wheel performance measured is sinkage and wheel rotational speed. The research produced two models of driving wheels, namely the standard fin type with a driving wheel diameter of 35 cm and a number of 8 fins and the open-close fin type producing a driving wheel diameter of 40 cm with 4 arcuate fins on the top surface of the driving wheel. Standard fin type drive wheels have smaller sinkage (11% on average) compared to open-close fin type wheels. The finned drive wheel with the open-close type has an average speed level that is 27.7% higher when compared to the standard finned type.Keywords – wheel drive, standard fins, open-close fins, sinkage, wheel speed

Abstract

This study discusses the conceptual design process of an Unmanned Aerial Vehicle (UAV) featuring Long Endurance Low Altitude (LELA) characteristics, intended for long-range surveillance missions. The design is based on a quantitative approach through the estimation of initial performance parameters such as wing loading, power loading, maximum lift coefficient (CLmax), and lift-to-drag ratio (L/D). Technical data were obtained from literature and preliminary numerical calculations, then used to determine the main geometric dimensions and power requirements of the aircraft. The design results show that a UAV with a take-off weight of 15.08 kg, wing area of 0.2317 m², and cruise power of 67.34 Watts is capable of flying for 79 minutes with an L/D ratio of 13.69. The center of gravity (CG) is located 0.454 m from the aircraft nose, indicating good longitudinal stability. This research provides an essential early- stage contribution as a foundation for further development in the preliminary design phase.
