Abstract

A measuring instrument plays important role in the biomedical measurement since the biological process in living organism generates very weak signal. Therefore, a reliable and sensitive measuring instrument is needed. In this study, a lock-in amplifier was analysed and tested. This paper presents an experiment to investigate the lock-in amplifier for biomedical measurement. An experiment using RC (resistor capacitor) tissue model to measure the voltage change related to impedance change was performed using a lock-in amplifier to evaluate the accuracy of the lock-in amplifier. Three different values of the capacitor in the RC tissue model were applied regarding to simulate small impedance changes. The measurement results were compared with the theoretical calculation and an impedance measurement system. An error analysis was conducted to investigate the accuracy of the measurement. The comparison result showed that impedance measurement using lock-in amplifier is an effective technique, which could able to measure very small voltage regarding impedance change in the RC tissue model.

Abstract

This study aims to determine the effect of the addition of mealworm frass and molasses on the proximate value of white oyster mushrooms. This type of research was an experiment using a completely randomized design (CRD) consisting of four treatments with three replications each. Test parameters include water content, ash content, crude protein, crude fat and crude fiber. Proximate data on water content, ash content, crude protein, crude fat and crude fiber were analyzed using analysis of variance (ANOVA) and Tukey's follow-up test with a 95% confidence level. The results showed that treatment with frass and frass molasses had an effect on water content, ash content, crude protein, crude fat, and a decrease in fiber content. Therefore, it can be concluded that the addition of mealworm frass and molasses affects the proximate value of the resulting oyster mushrooms.Keywords: White Oyster Mushroom, Flour Caterpillar Frass, Molasses, Proximate.

Abstract

Tujuan penelitian ini yaitu untuk mengetahui bagaimana mengembangkan serta mengetahui tingkat kelayakan modul pembelajaran Programmable Logic Controller (PLC) Omron pada mata kuliah PLC di Program Studi Pendidikan Vokasional Mekatronika. Penelitian ini menggunakan jenis penelitian R&D atau Penelitian Pengembangan dengan acuan model pengembangan 4D (Four-D) yang terdiri dari 4 tahapan yaitu tahapan define (Pendefinisian), design (Perencanaan), dan develop (Pengembangan). Tahapan keempat yaitu disseminate (Penyebarluasan) tidak dilakukan dikarenakan penelitian ini dikhususkan untuk satu prodi pada Fakultas Teknik, Universitas Negeri Makassar. Data penilaian kelayakan modul dikumpulkan berdasarkan kuesioner dengan menggunakan google form. Tingkat kelayakan modul ditentukan berdasarkan hasil penilaian validator ahli .Validator atau ahli terdiri dari validator materi dan validator media serta Mahasiswa sebagai respon terhadap modul Programmable Logic Controller. Hasil penelitian yang diperoleh adalah proses pengembangan modul pembelajaran PLC menggunakan model 4D yang dimodifikasi. Berdasarkan hasil penilaian tingkat kelayakan modul yang diperoleh dari ahli materi sebesar 85,29% ( Sangat Layak). Sedangkan dari ahli media sebesar 91,44% ( Sangat Layak). Dan respon mahasiswa sebesar 83,65% (Sangat Layak). Berdasarkan data tersebut dapat disimpulkan bahwa modul pembelajaran PLC yang dihasilkan layak untuk digunakan dan diimplementasikan sebagai media pembelajaran mahasiswa di Program Studi Pendidikan Vokasional Mekatronika.
