Desain Proportional Integral Derrivative (Pid) Controller Pada Model Arm Robot Manipulator

Dalam rangka menuju proses industrialisasi modern di negara Indonesia, harus didukung dengan teknologi yang canggih, contoh nya adalah arm robot manipulator. sebagai pelaku proses produksi sehingga dihasilkan ketepatan,kepresisian, dan kefektifan pada proses produksi. Dengan hal tersebut dibuat sebuah desain kontrol PID pada arm robot manipulator dengan tujuan menghasilkan tingkat presisi dan kestabilan yang lebih baik. Kontroler tersebut didesain, disimulasikan, dan diaplikasikan pada hardware dengan menggunakan software MATLAB/Simulink, kemudian dianalisa kestabilannya dengan metode root locus. Akrilik digunakan sebagai material pada body arm robot. Selanjutnya komponen utama seperti, potensiometer sebagai analog input, motor DC sebagai penggerak setiap link, serta Arduino Mega 2560 sebagai mikrokontroler. Akrilik dipilih karena ringan, kuat dan tahan lama.Dalam penelitian ini akan dilakukan penyempurnaan konstruksi mekanik arm robot manipulator yang sudah ada, pemasangan hardware elektronik, dan pemrograman mikrokontroler dengan menggunakan software MATLAB pada Arduino Toolbox. Dari penelitian yang telah dilakukan, model arm robot manipulator dapat bergerak lebih smooth sesuai dengan input pergerakan potensiometer, dan berada posisi kestabilan saat dianalisa dengan menggunakan root locus

Capturing Guest Dynamics in Metal–Organic Framework CPO-27‑M (M = Mg, Zn) by ²H Solid-State NMR Spectroscopy

Metal–organic frameworks (MOFs) are promising porous materials for gas separation and storage as well as sensing. In particular, a series of isostructural MOFs with coordinately unsaturated metal centers, namely, CPO-27-M or M-MOF-74 (M = Mg, Zn, Mn, Fe, Ni, Co, Cu), have shown exceptional adsorption capacity and selectivity compared to those of classical MOFs that contain only fully coordinated metal sites. Although it is widely accepted that the interaction between guest molecules and exposed metal centers is responsible for good selectivity and large maximum uptake, the investigation of such guest–metal interaction is very challenging because adsorbed molecules are usually disordered in the pores and undergo rapid thermal motions. ²H solid-state NMR (SSNMR) spectroscopy is one of the most extensively used techniques for capturing guest dynamics in porous materials. In this work, variable-temperature ²H wide-line SSNMR experiments were performed on CPO-27-M (M = Mg, Zn) loaded with four prototypical guest molecules: D₂O, CD₃CN, acetone-<i>d</i>₆, and C₆D₆. The results indicate that different guest molecules possess distinct dynamic behaviors inside the channel of CPO-27-M. For a given guest molecule, its dynamic behavior also depends on the nature of the metal centers. The binding strength of guest molecules is discussed on the basis of the ²H SSNMR data
