ANALISA CLOCK GENERATOR PADA RANGKAIAN POWER SUPPLY UNTUK APLIKASI TRIGER IC TTL DILABORATORIUM DIGITAL PROGRAM STUDI TEKNIK ELEKTRONIKA DI POLITEKNIK NEGERI MALANG

The good performance of a clock generator circuit in the power supply for triger TTL IC is very influential on the success of the lab. A series. Therefore, the effectiveness of use must be adapted to its use in the practicum. To create a clock generator circuit as a source of pulses from a digital counter IC, a timer IC can be used. This pulse generator or clock generator can be used for clock sources in making counters up and down. Clock generators are often referred to as clock generators. The pulse generator in making the circuit is often used linear integrated circuit (IC: Integrated Circuit). A linear IC that is commonly used in general is usually the NE555 which is a timer IC. As a timer it can also be used analogically as a Clock Generator or pulse generator which can generally generate the frequency or time as needed.

Single-Bit, Self-Powered Digital Counter Using a Wiegand Sensor for Rotary Applications

This work explores energy harvesting from rotary motion using a Wiegand sensor, which is a magnetic sensor that induces a voltage pulse when the magnetization is reversed. The main feature of the Wiegand sensor is that a pulse is generated regardless of how slowly magnetism reversal occurs. Self-sustained sensors play major roles in advancing the Internet of Things (IoT) and wireless sensor networks (WSN). In this study, we identified a linear relationship between rotational motion, magnetic field reversal, and the rotational frequency generated by the Wiegand sensor. In addition, the maximum energy per pulse and its dependence were derived analytically. A maximum energy of 130 nJ per pulse was reported for the sensor used. We developed a single-bit, self-powered digital counter that was sufficiently driven with 38 nJ of energy. In this study, single rotations were measured without the need for external power.

Counter-hegemony of the East Java Biennale art community against the domination of hoax content reproduction

This research analyses and describes in detail how the digital biennale activities that are a part of the Indonesian Digital art community has become a form of criticism and silent resistance to the social hegemony. It refers to the ideology, norms, rules, and myths that exist in modern society in Indonesia, especially the reproduction of hoax content. Hoax refers to the logic people who live in a world of cyber media with all of its social implications. This phenomenon is a problem, and it is at the heart of the exploration of the art community in East Java Biennale. The critical social theory perspective of Gramsci’s theory forms the basis of this research analysis. The qualitative research approach used a digital ethnomethodology research method focused on the online and offline social movements in the Biennale Art Community. The data collection techniques used were observation and non-active participation in the process of reproduction-related to the exhibition of Indonesian Biennale digital artworks. It was then analyzed using Gramsci’s hegemony theory. The purpose of this study was to describe the process of social movements in a digital format conducted by the Indonesian Biennale when reproducing works of art to counteract the dominance and hegemony of the Hoax phenomenon in Indonesia. The benefit of this research was that it obtained a preposition of Gramsci’s hegemony theory in the world of digital art as created by contemporary Indonesian Biennale artists. Digital technology has had a tremendous effect on the media industry, government, trade, informal industry sector, human resources, urban planning, services, disaster relief, health, education, religion, artistic and cultural expression, in addition to various other fields. The conclusion obtained from this research is that there is a formation of a new hegemony, a digital hegemony. This new hegemony is of particular concern for the digital artists in East Java Biennale. Through the digital format works, the artists also try to communicate their art as a form of silent resistance, protest, and criticism of the hegemony that occurs in society, referring to the ideology, norms, and myths. It can be called a digital counter-hegemony.s

The impact of the application of knowledge economics in the Kingdom of Saudi Arabia: أثر تطبيق اقتصاد المعرفة على حل مشاكل الإيرادات العامة في الشركة السعودية للكهرباء: دراسة مقارنة

This study dealt with the impact of the application of knowledge economics in the Kingdom of Saudi Arabia on the increase of revenues according to Vision 2020 of Electricity Company، comparing with Sudan case. The study problem was to measure the effect of using digital counter in Saudi Arabia. The historical approach, the comparative approach and the deductive approach were followed. The most important findings of the study were: There is a positive relation between using Knowledge economics and Increasing revenue, reducing administrative and financial expenses. The study recommended that knowledge economies should be applied in Saudi Electricity Company to structure jobs, reduce administrative expenses, improve the job quality and financial performance by increasing revenues by retrieving debts from individuals, bodies, institutions and governmental bodies, and to be the cornerstone for launching the Kingdom towards the application of knowledge economics in all economic fields, and in all governmental sectors.

Conveyor Control System Product Calculation Based On Programmable Logic Controller

The purpose of this study is design and create a product counter control prototype control system based on a programmable logic controller. Using the ladder diagram programming language with cx-programmer 9.5 software that can be applied as commands in the PLC and produce an output that is used to control and drive the product counter conveyor prototype.

The test results show that the design of the tool can work well in the process of calculating the number of products.Keyword : Control System, conveyor, proximity sensor, DC motor

A Hydraulic Piloting Concept of a Digital Cylinder Drive for Exoskeletons

The use of a digital cylinder drive for exoskeletons was proposed in the recent year as a means to save weight, installation space, and energy. Also the hydraulic actuation of the switching valves of the digital drive was brought into discussion, in particular by a so called hydraulic digital counter concept. That concept was originally invented to realize a digital hydraulic amplifier. It uses a mechanical input and feedback, transfers this into binary switching states of the valves which switch the chambers of the digital cylinder either to tank or system pressure. It is now reconsidered with a hydraulic input, a special design of the valves appropriate for the sub-kilowatts power ranges of exoskeletons, and a special control strategy. The configuration of this system with a true binary counting property requires the input pressure thresholds to grow exponentially with the number of binary stages of the drive. That limits the number of feasible stages to approximately five or six, complicates the mechanical parts of the valves which realize the hysteretic response to the pilot pressure, and increases the hydraulic power for valve actuation. To overcome these problems the system is configured as a quasi binary counter which jumps over certain digits if the input flow is monotonous, thus, requires a reversal of input flow to realize those digits. A theory and a numerical model of the counter in this configuration and a proper counting control strategy of the hydraulic input are presented. With this much higher number of digits can be realized and valve design and configuration are eased.
