Sensor ultrasonic yang digunakan untuk menangkap obyek dikopel dengan motor DC servo agar dapat digerakkan kearah kanan dan kiri dengan simpangan sudut 360°. Permasalahan yang terjadi dengan putaran 360O adalah mengatasi terlilitnya kabel sensor ultrasonic dalam mekanis radar tersebut. Sehingga dibuat dua buah lempengan yang akan menghunbungkan lempengan yang statis dan lempengan yang dinamis dengan empat jalur untuk koneksi ke terminal sensor. Visualisasi obyek yang tertangkap radar (sensor ultrasonic) akan ditampilkan pada layar komputer dengan visualisasi grafik dan memberikan tanda beep setiap menangkap obyek yang ada di depan sensor. Simulasi ini dibuat untuk mendeteksi benda sampai pada jarak 40 cm, dengan membuat skala 1:10 sehingga 40 cm sama dengan 4 meter. Perangkat lunak yang digunakan memvisualkan obyek yang tertangkap radar Arduino menggunakan Processing karena software ini sangat mudah komunikasi antar platform. Hasil pengujian  alat ssudah sesuai dengan tujuan, tetapi masih memiliki rata-rata kesalahan dalam melekukan pengukuran jarak sebesar 0,225.

Abstract

This paper proposes an improved Maximum Power Point Tracking (MPPT) algorithm for photovoltaic (PV) systems under partial shading conditions. The proposed method enhances the widely used Incremental Conductance (IC) algorithm by incorporating an incremental fuzzy control technique. The conventional IC algorithm suffers from limitations in adapting to rapidly changing irradiation conditions due to its fixed step size. The proposed Inc-Fuzzy algorithm dynamically adjusts the step size based on the change in power and voltage, enabling it to better track the Global Maximum Power Point (GMPP) under partial shading. Simulation results demonstrate that the Inc-Fuzzy algorithm achieves an average accuracy of 98.29% under constant irradiation and outperforms the conventional IC algorithm by 1.69% in terms of captured power during sudden irradiation changes. This improvement highlights the effectiveness of the Inc-Fuzzy approach in enhancing the performance of MPPT for PV systems under challenging operating conditions.

Abstract

Boilers experience frequent problems, such as scale formation, unstable steam pressure, incomplete combustion, and difficulty starting. Therefore, this study uses a quantitative method with the Failure Mode and Effect Analysis (FMEA) approach, which aims to determine maintenance and prevention to minimize these problems. This method determines the failure priority obtained from the Risk Priority Number (RPN) calculation based on assessment factors such as severity, frequency of occurrence, and the likelihood of failure being detected in each component. The results of these calculations indicate that the steam drum component falls into the highest category, with an RPN of 32. The other 12 components fall into the medium category: the feed water pump, electrode, photocell, nozzle, blower fan, solenoid valve, fuel pump, blowdown valve, main steam valve, scum valve, non-return valve, and gauge glass, with RPN values ranging from 12 to 24. Furthermore, the components in lowest category include the fuel filter, safety valve, and manometer, with RPN values ranging from 8 to 10. Therefore, the recommended improvements based on the FMEA results can be used as evaluation material to ensure the effectiveness of the improvements. Furthermore, regular boiler maintenance and monitoring are required, especially for components such as the steam drum, which requires additional routine maintenance schedules, repeated evaluations related to water treatment, and determining appropriate repairs for any steam drum failures.
