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

Dalam penelitian ini, dilakukan penurunan zat methylene blue menggunakan limbah dari cangkang biji kelapa sawit. Hasil optimum pada variasi konsentrasi dengan pengadukan 200 rpm terjadi pada menit ke 90 pada konsentrasi 1, 2, dan 3 mg/L. Hasil penurunan adsorpsi sebesar 0,019; 0,022; dan 0,025 mg/L. Pada variasi kecepatan pengadukan dengan konsentrasi methylene blue 1 mg/L, nilai optimum terjadi pada waktu 90 menit. Hasil penurunan adsorpsi pada kecepatan pengadukan 100, 200, 300, 400, dan 500 rpm adalah 0,006; 0,022; 0,053; 0,072; dan 0,083 mg/L. Pada percobaan Pengaruh Konsentrasi terhadap Persen Removal Waktu optimum adsorpsi methylene blue terjadi di menit 90. Persen removal adsorpsi dengan variasi konsentrasi 1, 2, dan 3 mg/L adalah 0,14715; 0,2967; dan 0,44625 mg/g. Efisiensi penyerapan berkisar antara 98,1% hingga 99,17%. Pada percobaan Pengaruh Kecepatan Pengadukan terhadap Persen Removal Waktu optimum adsorsi methylene blue terjadi di menit 90. Persen removal maksimal dengan variasi kecepatan pengadukan 100, 200, 300, 400, dan 500 rpm adalah 0,1491; 0,1467; 0,14205; 0,1392; dan 0,13755 mg/g. Persentase penyisihan adsorpsi berkisar antara 99,4% hingga 91,7%. Berdasarkan kinetika adsorpsi methylene blue bahwa Laju pengadukan yang terlalu lambat atau terlalu cepat dapat mempengaruhi efisiensi proses adsorpsi.

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.
