Laboratory Facilities
Laboratory Room
The Electronics and Instrumentation Laboratory (ELINS) at the Department of Physics, Universitas Diponegoro, adheres to international standard regulations, including the implementation of the 5S workplace culture (Seiri – Sort, Seiton – Set in order, Seiso – Shine, Seiketsu – Standardize, and Shitsuke – Sustain).
Several supporting facilities available in the laboratory include a 5GHz Wi-Fi router, a first aid kit, fire extinguisher, storage lockers, air conditioning, an LCD projector, safety signs, three types of waste bins, and many other supporting amenities. All laboratory facilities are available for use by every lab user without exception.
Oscilloscope
The ELINS Laboratory is equipped with two types of oscilloscopes: digital and analog. An oscilloscope is an electronic measuring instrument used to display and analyze the waveform of electrical signals. It is equipped with a cathode ray tube (CRT), where an electron-emitting device projects an electron beam onto the screen of the CRT.
The analog oscilloscope is primarily used for student practical sessions due to its more complex manual operation, while the digital oscilloscope is designated for faculty and student research projects.
Function Generator
A Function Generator is an electronic testing instrument capable of producing various waveform shapes. The waveforms that can be generated by a Function Generator include sine waves, square waves, sawtooth waves, triangular waves, and pulse waves. This functionality differs slightly from that of an RF Signal Generator or an Audio Signal Generator, which typically focus only on generating sine and square waveforms.
3D Printer
3D printing is a process in which material is joined under computer control to create a three-dimensional object, with the material added together (such as liquid molecules or powdered grains that are fused). 3D printers are commonly used in prototyping. Objects can have various shapes or geometries and are usually produced using digital model data from a 3D model derived from an Additive Manufacturing File (AMF). Several techniques are used, such as stereolithography (SLA) or fused deposition modeling (FDM). A 3D printer constructs a three-dimensional object from a computer-aided design (CAD) model or AMF file, typically by successively adding material layer by layer.
Microcontroller
A microcontroller is a small computer packaged in the form of an Integrated Circuit (IC) chip and is designed to perform specific tasks or operations. Essentially, a microcontroller IC consists of one or more processor cores (CPU), memory (RAM and ROM), and programmable input and output devices.
Basic Electronics Trainer
The ELINS Laboratory is equipped with a comprehensive module for Basic Electronics practical learning. The Basic Electronics Trainer can be used for experiments such as Ohm’s Law, Kirchhoff’s Law, passive filters, diode rectifiers, MOSFETs, relays, and more. This module can also be used for various educational purposes in electronics.
Electrical Measuring Instruments
The ELINS Laboratory is equipped with various electrical measuring instruments, including digital and analog multimeters, wattmeters, AC ammeters, and many more. Both analog and digital multimeters can be used to measure DC current and voltage, AC voltage, resistance, capacitor capacitance, as well as to test conductivity and diodes.
PLC Kit Trainer
A Programmable Logic Controller (PLC) is a microprocessor used for industrial automation processes such as monitoring and controlling machines on a factory assembly line. A PLC is equipped with input and output devices that interact with external components such as sensors, relays, magnetic contactors, and others. The programming language used to operate a PLC differs from standard programming languages. It uses Ladder Logic, which consists solely of input-process-output structures. It is called “Ladder” because the visual representation of the programming language resembles the rungs of a ladder.
