Tujuan dari penelitian ini adalah pemanfaatan sensor fotodioda yang dilengkapi dengan penguat operasional IC LM 358 untuk mendeteksi api yang berasal dari sebuah sumber. Pertama-tama, detector (sensor) akan menerima cahaya yang dipancarkan oleh api dengan merespons panjang gelombang optik tertentu selama terjadi kebakaran. Sensor api merupakan sensor yang mempunyai fungsi sebagai pendeteksi nyala api, di mana api tersebut memiliki panjang gelombang antara 760 nm – 1100 nm. Besaran fisika yang dapat dijadikan acuan untuk menentukan jarak api adalah intensitas radiasi panas yang dipancarkan oleh api. Sensor ini menggunakan inframerah sebagai transduser dalam mendeteksi kondisi nyala api. Oleh karena itu, melalui penelitian ini kami berusaha untuk mengembangkan prototipe yang baru, murah, dan sederhana, berupa perangkat pengindraan jarak api yang terbuat dari sensor fotodioda. Sebuah filter inframerah akan diintegrasikan dengan fotodioda, dan intensitas radiasi panas. Fotodioda ini akan dioperasikan dalam mode fotokonduktif, di mana sumber tegangan positif DC terhubung ke katoda. Sedangkan anoda terhubung ke terminal keluaran dan resistor bertindak sebagai pembagi tegangan. Hasil pengujian menunjukkan bahwa sistem sensor jarak api fotodioda dapat mendeteksi api dengan jarak maksimal 110 cm dan tegangan 0.1 Volt. Semakin jah jarak api maka semakin kecil intensitas cahaya dan tegangan yang dihasilkan. Sistem sensor fotodioda pendeteksi api yang telah dibuat dapat bekerja sesuai dengan yang diharapkan, di mana buzzer dan indikator LED juga dapat berfungsi dengan baik.

PLTP LMB 1 performs a First-Year Inspection after operating for one year to inspect and repair equipment after the operation. After these activities, a performance test needs to be carried out to determine the effectiveness and success of these activities. ASME PTC 46: 1996 is a widely-used standard for analyzing the performance test of thermal power plant systems, which includes plant heat rate, power output, specific mass consumption, and more. The purpose of the testing is to evaluate the results of system improvements. Calculation and comparative analysis are performed to determine the system's condition during warranty, commissioning, and testing, as well as after one year of operation and post-first year inspection. After testing, the thermal performance of PLTP LMB 1 was obtained as follows: The corrected net plant heat rate (NPRH) was 18923 kJ/kWh, the corrected net power output was 56,417 MW, and the net specific mass consumption (NSMC) was 6,881 tons/MW. Based on the data guarantee, the thermal performance value of PLTP LMB1 is still below the required value, so it can be concluded that the thermal performance value of PLTP LMB1 is in good condition. The isentropic turbine efficiency value decreased by 2.1% from its design value of 85% to 82.9%, which was caused by suboptimal heat energy absorption by the turbine above the design pressure of 5 bar.

Primary concern of optical communication system is the signal loss, which need to be traced precisely to enhance the efficiency of the system. Among numerous available techniques, optical time domain reflectometer (OTDR) is the most suitable one for characterizing and tracing the losses. It measures the fraction of a probe pulse that scatters back from the fiber optic cable. Due to the presence of small levels of backscattering in single-mode fiber at long wavelengths, very sensitive optical detector is necessary to achieve sufficient range performance. In the present research, a novel yet simple approach has been demonstrated to understand the range of optical fiber cable feasibility on fault detection and rectification technique. The actual place of fault is marked with the variation in the measured values of OTDR. Thus, it becomes a difficult task to trace and locate the actual place of fault detection, which leads to an inefficient rectification method. The observed values of OTDR shows a gradual decrease of accuracy in locating the actual place of fault. To resolve these issues, here we try to develop an algorithm which is able to easily and efficiently trace the exact location of fault on earth.

This paper delivers a systematic review and a bibliometric survey analysis of Light-Fidelity (Li-Fi) indoor implementation in Next Generation Network (NGN). The main objective of this study is to design a communication network based on NGN-Li-Fi for the indoor implementation which aims to increase user Quality of Service (QoS). The main merits and contributions of this study are the thorough and detailed analysis of the review, both in literature surveys and bibliometric analysis, as well as the discussion of the implementation model challenges of Li-Fi in both indoor and outdoor environments. The issue articulated in an indoor communication network is the possibility of intermittent connectivity due to barriers caused by line-of-sight (LOS) between the LED transmitter and receiver, handover due to channel overlap, and other network reliability issues. To realize the full potential and significant benefits of the Next Generation Network, challenges in indoor communication such as load-balancing and anticipating network congestion (traffic congestion) must be addressed. The main benefit of this study is the in-depth investigation of surveys in both selected critical literatures and bibliometric approach. This study seeks to comprehend the implications of Next Generation networks for indoor communication networks, particularly for visible light communication channels.

ABSTRAKAda kebutuhan untuk peningkatan kualitas kontrol pengecekan akurasi warna bumper yang diproduksi di PT. Sugity Creatives. Kebutuhan ini disebabkan oleh berbagai pekerjaan repetitif, tidak efisien, dan relatif lama. Sesuai pengamatan, pengecekan membutuhkan waktu 45 detik, validasi data manual selama 15 detik dan pencatatan di kertas selama 60 detik. Sehingga total proses adalah 120 detik. Di artikel ini, kami mengusulkan sebuah prototipe menggunakan Konica Minolta CR400 chromameter. Prototipe ini terdiri dari dua komponen utama yaitu Raspberry Pi-4 sebagai pengontrol dan penyimpan data, dan sensor spektrometri AS7341 untuk mengukur spektrum bumper setelah selesai dilakukan pengecatan. Berdasarkan hasil pengujian, prototipe mampu mereduksi waktu inspeksi kualitas dari 120 detik menjadi 40 detik, termasuk pengukuran, validasi warna, dan juga pencatatan di spreadsheet. Validasi juga memiliki akurasi 100% sesuai dengan hasil validasi chromameter CR400 setelah prototipe dikalibrasi dengan sampel bagus dan reject. Namun, risiko kesalahan manusia selama perekaman data menyebabkan kesalahan validasi mungkin tidak dapat dihindari.Kata kunci: Raspberry Pi-4, AS7341, Chromameter, Spektrometri, SensorÂ ABSTRACTThere is a need to improve the quality control process efficiency for bumper color accuracy checking at Sugity Creative Companies. This need caused by several repetitives, inefficient, and relatively working time. As we observed, there is 45 seconds for checking process, 15 seconds for manual validation, and 60 seconds for data writing on paper. Thus, total processing time is 120 seconds. In this paper, we propose an improvement through a prototype using Konica Minolta CR400 chromameter. This prototype consists of two main components, namely Raspberry Pi-4 as controller and storage, and AS7341 spectrometry sensor for measuring the spectrum of the bumper color after being painted. According to our experimental result, prototype can reduce the inspection quality time from 120 to 40 seconds over the measurement, color validation, and data recording in the spreadsheet. Validation also has 100% accuracy compared to the CR400 chromameter after it is calibrated to the good and rejected samples. Moreover, the human error riskÂ during the data recording caused the validation error is might inevitable.Keyword: Raspberry Pi-4, AS7341, Chromameter, Spectrometry, Sensor
