Abstract

This study presents the design and implementation of a Luenberger Observer algorithm for state estimation in a liquid storage tank system. The methodology includes system parameter identification, data preprocessing, observer gain calculation using pole placement, and simulation in MATLAB and Simulink. To reflect real-world conditions, synthetic disturbances were added and the input signal was normalized to improve numerical stability. Quantitative evaluation was conducted by comparing the system output with the observer’s estimated output. Simulation results demonstrate that the observer effectively tracks the system dynamics, yielding a root mean square error (RMSE) of 7×10?? m and a near-zero steady-state error. The observer's robustness was also tested systematically through increasing levels of synthetic measurement noise, showing stable and accurate performance even under 6% noise conditions. These findings confirm that the proposed algorithm provides reliable and responsive state estimation, with strong potential for practical application in control systems for dynamic fluid environments

Abstract

Masalah stunting Dapat terjadi pada semua kelompok umur. Anak balita merupakan kelompok umur yang rawan gizi dan rawan penyakit, hal ini di sebabkan karena anak balita baru berada dalam masa transisi dari makanan bayi ke makanan dewasa. Stunting adalah masalah gizi utama yang akan berdampak pada kehidupan sosial dan ekonomi dalam masyarakat Akibat dari stunting lainnya, menurut beberapa penelitian yaitu, meningkatnya risiko infeksi dan kematian, keterlambatan perkembangan mental dan motorik, serta penurunan kapasitas kerja. Jenis penelitian ini merupakan penelitian analitik deskriptif dengan menggunakan pendekatan Cross Sectional. Besar sampel dalam penelitian ini sebanyak 30 pasien. Data penelitian ini diambil dengan menggunakan kuesioner.dan dianalisis dengan menggunakan uji chi square dengan tingkat kemaknaan 0,05. Hasil penelitian ini menunjukkan berdasarkan hasil analisis dengan menggunakan uji chi-square diperoleh nilai significancy sebesar 0,000 (p < 0,05), terhadap Hubungan status gizi dengan terjadinya stunting, sedangkan untuk Hubungan ASI eksklusif dengan terjadinya stunting diperoleh nilai significancy sebesar 0,000 (p < 0,05). Hasil penelitian ini Dapat dijadikan sebagai literatur, khususnya dalam penerapan asuhan keperawatan tentang Faktor-faktor yang berhubungan dengan terjadinya stunting pada balita Umur 1-3.

Abstract

A frequen problem in riau province is the problem of traffic lights at zebra crossing, where  drivers often cross the stop line. Many drivers, especially at traffic lights, cross the stop line, potentially causing congestion and accidents. To overcome these problem, technology is needed that can detect and monitor the number of zebra crossing violation remotely. One of the technological solutions is the use of iot-based esp32 cam camera modue and pir sensor, sepaker. This research aim to create a device that can detect drivers eho exceed the stop line at the zebra crossing violation detecion system at iot-based traffic lights. Five violations were tested using a stopwatch to measure the  desice’s response time. Sensor 1 nad 2 detected the fastest violation at 0.34 seconds and 0.55 second respectively. Buzzer has a response time of 0.34 seconds, esp32 cam has a response time of 0.55 seconds, and telegram has response time occurs at a distance of 19 cm. The results showed that the pir sensor can detect the vehicles that cross the stop line, and the esp32 cam can capture image of the telegram as evidence of the violation within a distance of 20 cm, outside  this range the sensor connot detect the violation

Abstract

The Mamuju River Estuary is an estuary whose role is to protect coastal ecosystems (mangroves, seagrasses, coral reefs) from the negative effects of intensification of land clearing upstream and coastal. Land clearing for various human needs encourages erosion resulting in high TSS (Total Suspended Solid) concentrations in river water bodies. This study aimed to determine the assimilation capacity of the Mamuju River estuary on TSS pollutants. The results showed that TSS concentrations still met the quality standard for marine biota (mangroves: <80 mg / l) with a lower distribution pattern when getting further away from the river mouth. The flushing time at the study site is 5.6 days so the river and seawater exchange is ± 65 times per year. The pollutant load was 586.11 tons/month. The value of the assimilation capacity reaches 255.57 tons/month. Based on these results it can be concluded that the Mamuju River estuary has experienced an overload of sediment.

Abstract

This study presents the design and implementation of a Kalman-Bucy filter for fault detection in DC motor systems, which are widely used in industrial drives and automation. Accurate state estimation is essential for ensuring reliable operation, particularly in the presence of measurement noise and parameter uncertainties. The proposed observer exhibits rapid convergence in speed estimation (less than one second) and strong robustness to measurement noise, achieving a Root Mean Square Error (RMSE) of 24.38 rad/s, closely matching the noise standard deviation (σᵥ = 23.01 rad/s). This close agreement indicates that the Kalman-Bucy filter operates near its theoretical optimal performance under Gaussian noise assumptions. Fault detection is carried out through residual analysis under three fault scenarios: ramp, inverse ramp, and square wave. Each scenario generates distinct residual patterns, providing clear indicators of both gradual and abrupt anomalies. Quantitative evaluation demonstrates high sensitivity (97.0% for ramp and inverse ramp, 94.1% for square), perfect specificity (100%), and a zero false alarm rate across all scenarios. These findings highlight the potential of the Kalman-Bucy filter as a reliable and computationally efficient approach for state estimation and fault indication using data representative of a real DC motor system. The results provide a valuable basis for developing predictive maintenance strategies and improving system reliability. Future work will focus on experimental implementation and validation to confirm its performance under real-world operating conditions.

Abstract

Pemahaman konsep kendali PID merupakan elemen penting dalam elektronika instrumentasi, terutama di sektor industri. Pembelajaran yang masih menggunakan metode simulasi, tentu hasilnya tidak sepenuhnya mencerminkan kondisi sebenarnya. Penelitian ini bertujuan untuk mengembangkan alat media pembelajaran sistem kendali PID praktis dengan tampilan antarmuka yang inovatif dan informatif untuk meningkatkan pemahaman mahasiswa di bidang teknik kendali. Alat ini menggunakan Arduino Uno sebagai perangkat akuisisi data dan perangkat lunak LabVIEW sebagai antarmuka. Sensor IR Optocoupler LM393, sensor tegangan, dan sensor ACS712 digunakan untuk membaca kecepatan putaran, tegangan, dan arus motor DC. Hasil pengujian menunjukkan bahwa sistem tanpa kendali menghasilkan kesalahan sebesar 16% sedangkan sistem dengan kendali PID menghasilkan kesalahan sebesar 4.4%. Selanjutnya, hasil pengujian terhadap gangguan kendali PID sistem mampu menjaga kestabilannya dengan baik dibandingkan tanpa kendali. Melalui uji evaluasi usability dengan mahasiswa sebagai responden menunjukkan nilai rata-rata sebesar 92,3 %. Jadi dengan demikian, alat ini dapat menjadi solusi efektif bagi mahasiswa untuk mempelajari konsep kendali PID secara langsung.

Abstract

Kualitas air merupakan parameter yang sangat penting untuk kelangsungan pertumbuhan dan perkembangan ikan. Kadar amonia dan pH pada air merupakan hal penting yang terkait dalam kualitas air. Pada penelitian ini telah dibuat dan dirancang suatu sistem monitoring kadar amonia dan pengontrolan pH air untuk budidaya ikan lele. Untuk pengukuran kadar amonia dan pH air, Penilitian ini menggunakan sensor pH-4502C untuk mendeteksi kandungan pH air dan sensor MQ-135 sebagai pengukur kadar amonia. Setiap sensor akan dihubungkan ke mikrokontroller nodemcu ESP-32 yang telah dilengkapi dengan sistem Internet of Things. Hasil pengukuran akan di kirim ke aplikasi telegram. Pada sistem ini nilai pH akan di jaga tetap netral sesuai dengan kebutuhan ikan lele yaitu 6-8, jika kurang atau lebih dari batas tersebut maka sistem kontrol akan bekerja secara otomatis untuk memberi larutan asam jika air memiliki pH lebih dari 8 dan akan memberi larutan basa jika air memiliki pH kurang dari 6. Pada sistem monitoring dapat dilakukan melalui aplikasi telegram sehingga kadar air dapat dipantau melalui smartphone maupun laptop. Hasil dari pengujian sistem ini menunjukan bahwa sistem dapat bekerja dengan baik dalam mengontrol kualitas air sehingga dapat menciptakan suasana kehidupan yang baik bagi kelangsungan pertumbuhan dan perkembangan ikan lele serta membantu pertumbuhan ikan sebesar 0,3 cm dalam 7 hari.
