Abstract

In this research, methylene blue was reduced using waste from green kerrang shells. Optimum results for variations in mass and time with masses of 0.1, 0.2, 0.3 grams and 0.1 mg/L methylene blue occurred at a mass of 0.3 grams with 60 minutes. Result of adsorption capacity. Optimum adsorption capacity for Methylene Blue with adsorbent from green mussel shell chitosan with a contact time of 10-60 minutes with variations in optimum adsorption time with a time of 10-60 minutes and a mass of 0.3 grams with an adsorption capacity of 3 mg/ g, From the results of this research, the mass of chitosan has an effect on decreasing the adsorption concentration, which is greater as the contact time increases. In this study, the largest adsorption capacity occurred at a mass of 0.3 grams. In this study, the maximum adsorption removal percentage in the mass variation was at 60 minutes, which means that at 10-50 minutes, the adsorption removal percentage was still gradually increasing with the highest result at 60 minutes with 98.9%.

Abstract

Automation systems are vital for production departments in industry. One of the automation systems used in almost all industries is the programmable logic controller (PLC). The widespread use of PLC has long been applied as a standard curriculum in vocational schools (SMK). The widespread use of PLCs in the industrial world certainly increases job opportunities for vocational students who have expertise and skills in this field. In connection with this, the electrical engineering study program at the University of Muhammadiyah Gresik held PLC Zelio training for students of SMK Muhammadiyah 3 Gresik. This Zelio PLC training includes training in PLC wiring and installation, as well as the use of its PLC software. This training was held at the University of Muhammadiyah Gresik campus in the Automation and Instrumentation Laboratory. At the end of the training, SMK students were given a simple assignment according to the training material, namely assembling a Zelio PLC and making a simple program. From these assignments, all students are able to compose and make simple programs. Meanwhile, based on the questionnaire related to this training, all students also gave a score between 4 and 5, which means the training was quite good and satisfactory. It is hoped that with this training, students have the expertise and skills, especially in the field of PLC and are ready to enter the workforce after graduation.

Abstract

This study proposes a Maximum Power Point Tracking (MPPT) method based on Particle Swarm Optimization (PSO) to enhance power extraction performance in Proton Exchange Membrane Fuel Cell (PEMFC) systems operating under dynamic and varying environmental conditions. The proposed method is designed to optimize the system's operating point to ensure that the power generated by the fuel cell is fully utilized. In this research, the PSO algorithm is integrated with an Interleaved Boost–Buck Converter (IBBC), which functions to reduce current ripple and improve the stability of the output power in the energy conversion system. This integration is expected to provide a faster and more efficient system response in adjusting to changes in operational conditions. One of the main challenges in implementing MPPT in PEMFC-based systems is the nonlinear characteristics of PEMFC itself, which are highly influenced by various external parameters such as operating temperature, hydrogen pressure, and membrane water content. Variations in these parameters can cause fluctuations in output voltage and current, making the maximum power point tracking process more complex. Therefore, an adaptive optimization method with good convergence ability is required. Simulation results demonstrate that the proposed PSO method achieves a tracking accuracy of up to 99.96% with a settling time of 2 seconds under varying membrane water content conditions. The PSO approach also outperforms the Fuzzy Logic and Cuckoo Search Algorithm (CSA) methods. These findings confirm that the integration of PSO and IBBC significantly improves both the accuracy and speed of MPP tracking in PEMFC systems.

Abstract

The preneutralizer unit is one of the important stages in the NPK fertilizer production process, functioning as the initial reactor for slurry formation through the netralization reaction between ammonia, sulfuric acid, and phosphoric acid. The reaction is exothermic and affects the energy distribution and operating conditions of the system. This study aims to analyze the mass and energy balance of the prenetralizer unit ini the NPK fertilizer production process based on actual operating data under steady-state conditions. The calculations were carried out by considering the mass flow rate of raw materials, material purity, water content, reaction stoichiometry, sensible enthalpy changes, and heat of reaction during the process. The mass balance result showed that the total mass entering and leaving the system was balance at 31,040 kg/h without mass accumulation. In additon, the exothermix heat of reaction became the largest energy contribution in the system, reaching 12,488,557.77 kJ/h. the main products formed were ammonum sulfate and monoammonium phosphate. The result indicate that the mass and energy balance approach can be used to evaluate the performance of the preneutralizer unit in the NPK fertilizer.
