Abstract-To date, the photodiode still the first choice component is used in optical communication, especially for visible light communication (VLC) system. It has advantages of speed, energy consumption, and sensitivity, compared to other devices (e.g. image sensor). There are many practical implementations of high-speed VLC which uses photodiode. Commercially available photodiode typically have specific characteristics, so that it needs some consideration to be used as optimal receiver devices in VLC system. In this paper, analysis of received power characteristics of the photodiode in indoor lineof-sight (LoS) channel of VLC system is discussed. MATLAB® simulation is used as approach model (student version). The experiments are done by changing several parameters such as the semi-angle half power of the transmitter, distance from the transmitter to receiver, room size, field-of-view (FOV), lens index and optical filter gain. From the results, it can be known that distance, room size, FOV and LED power factor to have linear characteristic against the received power of commercial photodiode. Also in LoS channel model, the gain of optical filter and lens index plays an important role in defining the characteristics of received power.

“…The results of this study indicate that VLC can be applied on the road and send information with a maximum distance of 1.5 m. In 2015, a study conducted by Azka et al [7] tried to transmit digital data in the form of files using the VLC system, this tool can communicate at a maximum distance of 30 cm between the transmitter and receiver at an angle of 0° and a range of 10 cm without interference from other objects. Other researches were done by Fuada et al [8], Deepa et al [9], and Qasin et al [10] that analyze VLC technology that will be used for those systems. Besides that, this technology has been implemented and applied indoors [11][12][13][14][15][16][17][18], underwater [19][20][21][22][23], vehicular [24], and internet network [25].…”

Visual impairment is the condition of someone who has a disorder or an obstacle in their vision. In this research, the implementation of light follower systems for visually impaired using visible light is proposed. This system can enable visually impaired people to determine orientation and support mobility, especially in an indoor situation, using visible light. The prototype of the visually impaired pathway was made as visible light communication (VLC) transmitter consisting of a 12 V power supply, light emitting diode (LED), MPEG-1 Layer-3 (MP3), and band pass filter (BPF) filter circuit. The VLC receiver is made a prototype of a blind stick consisting of a photodiode, amplifier, buzzer, timer, and 9 V battery. The measurement of this system uses acrylic and color filters with system accuracy taking into account the angle and conditions when the fluorescent lights are turned on and off. This result showed the system could transmit audio signals at a frequency of 3000 Hz. Furthermore, the comparison results showed that the quality of measurements without using a filter is better than using a filter. The output voltage value without using a filter with an angle of 700 degree is 7.19 Vp-p, meanwhile using a filter with an angle of 700 degree is 6.48 Vp-p.

“…Simulasi menggunakan alat bantu komputer merupakan langkah awal dalam rancang bangun suatu alat atau sistem, hal ini bertujuan agar penulis mampu mengetahui cara kerja alat apakah berjalan sebagaimana mestinya. Selain itu juga dipergunakan untuk mengetahui perilaku dan karakteristik dari suatu rangkaian, (misalnya: temperatur [5], noise [6], received power [18], bode plot, dsb.). Dengan melakukan proses simulasi, maka proses engineering design akan lebih mudah, praktis, efektif, dan efisien dari segi effort, waktu, tenaga, dan biaya.…”

Graphical abstract AbstractGenerally, simulations are used as the first approach to implement a particular system, from simple to complex systems. In the electronic circuit, simulation can be done in order to know the working principle of the circuit. The aim of this article is to design a digital control circuit based on digital IC for cracker drying device. The PROTEUS 7.0 with the student version is used as a simulator tool. The PROTEUS® consists of two software that each of them have a specific purpose, i.e. ISIS® which has been embedded in SPICE® macro model. Thus, able to simulate electronic circuits with an interactive display, and then ARES® is dedicated to PCB layout only. The advantages of PROTEUS® e.g. easy to operate; has a good of user interactivity; Contains a large selection of active components (such as BJT transistors, MOSFET transistors, IC, IGBT, diode, and etc.), passive components such as resistors, capacitors and inductors, components of input and output, and sensor devices from various vendor. The designed control circuit is consist of four main parts, i.e. counter circuit as timer. In this case, we use two digits Sevensegment as clock representative from 12 PM to 12 AM. ii) circuit for controlling the DC motor with CW mode and CCW mode; iii) rain sensor circuit; and iv) light sensor circuit, in this paper we use the Light Dependent Resistor (LDR). This paper is focus on control circuit only.
