Abstract

The integration of the Internet of Things (IoT) technology into a Photovoltaic-Solid Polymer Electrolyte (PV-SPE) system offers an innovative solution for monitoring and optimizing hydrogen production in real time. This study presents the design and implementation of an IoT-based monitoring system for a PV-SPE hydrogen production system, utilizing ESP32 microcontrollers to collect and transmit critical operational data, including voltage, current, temperature, humidity, and hydrogen flow rate, to the Adafruit IO cloud platform. A Maximum Power Point Tracking (MPPT) controller was employed to optimize power transfer from the solar panel to the SPE electrolyzer, ensuring maximum efficiency in the electrolysis process. Experimental results confirmed that hydrogen production rates correlate directly with PV power output, with the IoT-enabled system providing efectively measurement compared to conventional methods. The system demonstrated stable data acquisition, real-time monitoring, and remote accessibility, allowing users to track hydrogen generation performance efficiently. This study concludes that the combination of IoT, renewable energy, and electrolysis technology enhances the efficiency, and scalability of hydrogen production systems

Abstract

This research discusses the design and implementation of an information system for laboratory equipment management at SMK 1 Sigli, specifically in the Fashion Design department. Manual management of laboratory equipment often leads to inefficiencies and errors in data recording. To address these issues, a computer-based system was developed using Microsoft Visual Basic and Microsoft Access, replacing the previously used Microsoft Excel-based system. The system automates several processes, such as data entry, equipment tracking, and report generation, improving operational efficiency. A needs analysis was conducted with laboratory managers to ensure the system design met the operational requirements. The development process included creating a user-friendly interface and an organized database structure. As a result, the system enables real-time monitoring of equipment, reduces errors, and speeds up decision-making related to maintenance and procurement. Feedback from laboratory staff indicates that the system successfully improves the accuracy and efficiency of equipment management. This research provides a practical solution that can be applied to other schools facing similar challenges in laboratory resource management.

Abstract

Pembangkit Listrik Tenaga Uap (PLTU) “Pelita” menggunakan batu bara sebagai bahan bakar utama. Batu bara yang dipasok ke PLTU “Pelita” berasal dari Provinsi Sumatera Selatan, Kalimantan Selatan dan Kalimantan Timur. Pasokan batu bara yang diterima dilakukan analisis proksimat dan penentuan nilai kalor yang dilakukan oleh PT Surveyor Indonesia. Penelitian ini dilaksanakan untuk menentukan karakteristik batu bara pada PLTU “Pelita” periode 2019 berdasarkan hasil analisis proksimat dan nilai kalor. Korelasi antara nilai hasil analisis proksimat dan nilai kalor pada batu bara dilakukan berdasarkan analisis statistik menggunakan metode regresi linear. PLTU “Pelita” pada periode 2019 menerima batu bara sebanyak 17.485,537 ton dari Provinsi Kalimantan Selatan melalui dua kali pengiriman, 252.834,199 ton dari Provinsi Kalimantan Timur melalui 23 kali pengiriman dan 259.138,715 ton dari Provinsi Sumatera Selatan melalui 34 kali pengiriman. Pasokan batu bara periode 2019 ini memiliki nilai rata-rata untuk parameter kelembaban, kandungan zat terbang, kandungan abu, kandungan karbon dan nilai kalor batu bara secara berurutan sebesar 29,70%; 34,41%; 3,05%; 32,73%; dan 4.647,71 kkal/kg. Batu bara dari Provinsi Kalimantan Selatan, Kalimantan Timur dan Sumatera Selatan memiliki nilai rata-rata untuk parameter kelembaban sebesar 27,45%; 29,98%; dan 29,58%; kandungan zat terbang sebesar 36,74%; 35,26%; dan 33,44%; kandungan abu sebesar 4,37%; 2,70%; dan 3,30%; kandungan karbon sebesar 31,44%; 31,94%; dan 33,60% serta nilai kalor batu bara sebesar 4.845,54 kkal/kg, 4.504,92 kkal/kg dan 4.773,68 kkal/kg. Korelasi kuat ditunjukkan oleh pengaruh nilai kelembaban (0,663) dan kandungan karbon (0,756) terhadap nilai kalor pada batu bara. Berdasarkan nilai fuel ratio, jenis batu bara yang diterima oleh PLTU “Pelita” periode 2019 adalah bituminus dengan zat terbang menengah-tinggi dan seluruh golongan subbituminus.

Abstract

The “Lentera” power plant is a 130 MW coal-fired power plant facility. The quality of the supplied coal to the “Lentera” power plant were tested using proximate and ultimate analysis to determine sulphur and nitrogen content. The production of SO2 and NOX emissions from coal combustion was affected by the sulphur and nitrogen content in the coal. Emission levels were observed using the Continuous Emission Monitoring System (CEMS). This research was conducted to determine the effect of the sulphur and nitrogen content in coal on the production of SO2 and NOX gas at "Lentera" power plant during June-December 2020. The analysis was done based on statistical analysis using simple linear regression methods and analysis of variance. Based on the content of sulphur, nitrogen and caloric value, coal from East Kalimantan Province has a lower value than coal from South Sumatra Province. The content of sulfur and nitrogen significantly affected the production of SO2 and NOX emissions. The higher the sulfur and nitrogen content in coal showed the higher the production of SO2 and NOX emissions. The caloric value of coal did not show a correlation with the production of NOX emissions.
