Abstract

The use of the 4–20 mA analog signal remains a foundational standard in industrial measurement and control systems, despite the continuous advancement of digital communication technologies. This study implements a hybrid validation approach that integrates the conventional 4–20 mA analog signal with HART (Highway Addressable Remote Transducer) digital communication for conducting Input/Output (I/O) loop testing on pressure transmitters. The primary objective is to ensure the accuracy and reliability of signal transmission from field instruments to control systems such as Programmable Logic Controllers (PLCs) or Flow Computers. Utilizing a HART modem and FieldMate software, analog signals are injected and digitally monitored to verify transmitter output against predefined tolerance standards. Test results indicate that all evaluated transmitters maintained an error level below the 0.25% threshold, in compliance with standards set by the Directorate of Metrology and ASTM/API guidelines. The integration of HART communication significantly enhances testing efficiency, diagnostic capability, and remote configuration flexibility, underscoring the critical role of hybrid validation approaches in modern industrial instrumentation systems

Abstract

Viskositas adalah merupakan ukuran kekentalan fluida yang menyatakan besar atau kecilnya gesekan didalam fluida. Penelitian ini bertujuan untuk mengetahuin nilai dari viskositas sebuah Oli dan mengembang alat ukur viskositas bola jatuh menjadi lebih modern karena menggunakan android sebagai basisnya. Dalam penelitinaan ini menggunakan Metode bola jatuh. Bola dijatuhkan secara bebas kedalam fluida oli. Untuk dapat mengetahui kecepatan bola jatuh, di luar pipa diberi Sensor untuk mendapatkan waktu tempuh bola dari titik satu ke titik dua pada jarak ketinggian tertentu, sehingga diperoleh data waktu tempuh bola jatuh (t) dan jarak tempuhnya (h). Nilai koefisien viskositas fluida ditentukan berdasarkan persamaan dari gayagaya yang bekerja pada bola magnet yang bergerak di dalam pipa. Gaya-gaya tersebut antara lain gaya apung, gaya gesekan berdasarkan hukum Stokes, dan gaya berat. Dari waktu yang didapatkan oleh Arduino dan dikirim keandroid maka andoid akan memproses data dan ditampikan layar smartphone, berdasarkan penelitian oli federal semakin tinggi type oli maka tingkat kekentalan akan semakin tinggi, seperti 1. Oli Federal tipe Matic 30 Eco maxx dengan nilai viskositas = 146.4234339 Pa/s, 2. Oli Federal tipe Matic Ultratec 10W-30 dengan nilai viskositas = 189.8221584 Pa/s, 3. Oli Federal tipe Matic Ultratec 20W-50 dengan nilai viskositas = 341.8454277 Pa/s. Dan oli yang sudah digunakan 1 bulan maka nilai viskositasnya akan menurun seperti Oli Federal tipe Matic 30 Eco maxx (Bekas 1 bulan) dengan nilai viskositasnya menjadi 94.49722275 Pa/s. Penelitian ini memudahkan pengguna dalam mengukur tingkat kekentalan oli yang baru maupun sudah digunakan.

Abstract

This research presents the design and implementation of an Internet of Things (IoT)-based Smart Keyless Locker integrated with face recognition technology to enhance security and efficiency in classroom locker management at Jakarta Global University. The system replaces conventional mechanical keys with biometric authentication to minimize risks associated with key loss, duplication, and unauthorized access. The hardware architecture consists of a Raspberry Pi as the primary processing unit for facial recognition, an Arduino Mega for actuator control, a camera module for image acquisition, solenoid door locks as locking mechanisms, load cell sensors for locker status detection, and an IoT-based notification system integrated with WhatsApp for real-time monitoring. The facial recognition process utilizes the Haar Cascade Classifier for face detection and the Local Binary Patterns Histograms (LBPH) algorithm for feature extraction and matching. System performance was evaluated under various conditions, including differences in lighting intensity, facial orientation, distance, and face coverings. Experimental results indicate that the system achieved a recognition success rate of 50% under the tested conditions, particularly within a distance range of 40–70 cm and adequate lighting. The average verification time ranged from 1.4 to 2.1 seconds depending on facial angle, while the WhatsApp notification system demonstrated reliable message delivery with an average delay of 4.75 seconds. Although recognition performance decreases when facial features are partially obstructed or when lighting is insufficient, the proposed system demonstrates the feasibility of integrating biometric authentication with IoT technology for modern classroom locker management applications.

Abstract

The utilization of renewable energy through rooftop photovoltaic (PV) systems serves as a strategic solution for mitigating climate change; however, their performance in tropical climates often exhibits a deviation between theoretical predictions and field reality. This study aims to evaluate the technical performance and economic viability of an on-grid 1.82 kWp rooftop PV system in Indonesia. The research employs a comparative quantitative approach by validating PVsyst simulation results against actual measurement data recorded from April to July 2024. The findings indicate a simulation overestimation, where actual energy production was 30.3% to 40.5% lower than PVsyst projections. A significant discrepancy was also observed in the Performance Ratio (PR), with the actual PR reaching only 55-59%, substantially lower than the simulated 81-82%. Despite these technical inconsistencies, the economic analysis confirms the project's financial feasibility. Under a 5.25% interest rate scenario, the study yielded a Net Present Value (NPV) of IDR 15.88 million, a Benefit-Cost Ratio (BCR) of 1.50, a Payback Period of 9.8 years, and a Levelized Cost of Electricity (LCOE) of IDR 974.88/kWh, more competitive than the national utility (PLN) tariffs. In conclusion, although tropical environmental factors such as high temperatures and dust accumulation reduce technical efficiency, rooftop PV investment in Indonesia maintains strong profitability and remains viable for implementation.
