Abstract

Steam power plant is a power plant which use coal as fuel to heating the water into superheated steam. The standard of efficient or not for a power plant can be seen from the value of plant heat rate. Plant heat rate is amount of energy required to generate one kWh electricity. The smallest of that is the best power plant. In general, the value of plant heat rate has increased than commisioning test after the power plant operated continously. The method used in the calculation of the steam power plant is energy balance method. Energy balance calculation method used by the standard of the American Society of Engineers Mechanichal Performance Test Code (ASME PTC). The value of plant heat rate is influenced by the value of turbine heat rate and boiler efficiency from steam power plant. Turbine heat rate is the required energy turbines obtained from heat transfer process to generate one kWh electricity, while boiler efficiency is an indicator from boiler performance of steam power plant by comparing the outputs and inputs. After calculation of plant heat rate at actual condition, the value of plant heat rate has increased than commisioning. The increrase of plant heat rate value is due to more losses which result degradation performance on the main components of the unis, such as : turbine, boiler, air heater and condenser. Therefore necessary corrective maintenance when first year inspection, so that the steam power plant can be re-optimal performance as at commisioning test.

Abstract

Jumlah penumpang kereta api Jabodetabek (commuter line) pernah mencapai 1 juta orang per hari. Commuter line melayani 6 rute dengan 80 stasiun, padatnya jadwal kereta perlu diimbangi dengan performa kereta api salah satunya saat pengereman. Pengereman melibatkan benda berbahan logam; blok rem, roda dan lintasan (rel). Gesekan antara roda kereta dan rel saat pengereman menimbulkan energi panas. Energi yang timbul dari pengereman kereta berpeluang untuk diteliti lebih lanjut. Penulis menganalisa timbulnya energi panas sebagai energi yang terbuang saat pengereman. Proses analisa menggunakan model pengereman kereta api. Penggerak kereta api dimodelkan dengan motor Direct Current (DC), pejal baja sebagai blok rem, roda dan lintasan (rel). Sensor kecepatan terkopel dengan motor DC, hasil deteksi sensor sebagai nilai kecepatan kereta (km/jam). Pulsa luaran sensor kecepatan diinput ke kontroler Arduino Mega, bersamaan dengan massa pejal didapatkan nilai gaya gesek (Fk) pengereman. Perubahan suhu permukaan pejal mempengaruhi besar energi yang timbul saat gesekan. Suhu pejal awal (T0) dipengaruhi suhu ruangan dan suhu pejal setelah gesekan (T1), perubahan suhu dikonversi ke bentuk energi. Analisis hubungan Fk dengan energi, pengujian data pada tiga jenis pejal berbeda massa. Data kecepatan dan suhu tiap pejal dibandingkan satu sama lain. Jika gaya gesek bernilai 1,864 Newton maka nilai Energi yang dihasilkan yaitu 37,31 Joule.

Abstract

5G mobile communication technology has attracted much attention in the past three years. However, the development of antennas that can cover three types of 5G bands at once has not been studied. This paper proposes an antenna covering the three frequency bands of 2.3 GHz, 3.5 GHz, and 26 GHz for 5G communication. The proposed antenna uses a microstrip patch design with 50-ohm inset feeding. FDTD mathematical analysis through simulation has been carried out and confirmed that the proposed antenna meets the required specifications in 5G technology. The simulation result shows that the proposed antenna has a good reflection coefficient in the target frequencies of -22.6 dB, -28.26 dB, and -22.48 dB, respectively.

Abstract

The hospitality industry is known for its high energy use. The operation of many 24-hour facilities raises energy demand. The Minister of Culture and Tourism's Decree Number KM.03/HK.001/MKP.02 requires that the quality of services and facilities be examined. Air conditioners, water heaters, exercise facilities, and conference rooms all require reliable electrical systems. Energy efficiency is essential, especially for facilities that use a lot of power, including heat pump water heaters in restrooms and fitness center equipment. Hotel A in Jakarta Tanah Abang, which has not yet implemented energy conservation measures, requires energy management systems and audits to improve efficiency. The Energy Consumption Intensity (IKE) is the amount of energy used by a building to increase a conditioned area over a month or a year. The study's goal is to determine IKE values for the period February 2024 to June 2024, as well as energy consumption patterns in accordance with the standards. This study included data collecting, interviews, observations, and direct measurements to determine the energy usage of each month and the entire facility. The IKE calculation approach yielded the following findings for each month: February 5,069701417 kWh/m2/month, March 5,235947214 kWh/m2, April 5,009387155 kWh (m2), May 6,335605837 kWh(m2), and June 6,127963403 kWh/m2. With scores ranging from 5 to 6,3 performance energy consumption, electricity falls into the "Very Efficient" category, eliminating the need for energy savings that could disrupt hotel operations.

Abstract

Modern industries require automation to enhance operational efficiency and productivity. This study designs and implements an automatic sorting system based on the Internet of Things (IoT) using a mini conveyor, ESP32 microcontroller, TCS3200 color sensor, servo motor, and the Blynk application. The system is designed to accurately detect object colors, sort objects based on color, and enable remote monitoring and control via mobile devices. Testing results indicate that the system can detect and sort objects with a high level of accuracy, although some errors occur due to changes in lighting conditions. The conveyor speed is consistently recorded at 0.335 m/s, while the system's response time, including color detection, servo movement, and application updates, operates within an optimal range. The Blynk application enhances the flexibility of real-time system control. This study demonstrates that IoT-based sorting systems can serve as an efficient solution to support industrial automation. Further development is recommended to improve color detection accuracy and expand the system's application in more complex industrial scenarios.
