Abstract

Good ride performance is one of the most important key attributes of a passenger vehicle. One of the methods to achieve this is by using Continuously Variable Transmission (CVT). This is because a CVT can provide an almost infinite ratio within its limits smoothly and continuously. The flexibility of a CVT allows the driving shaft to maintain a constant angular velocity over a range of output velocities. New developments in gear reduction and manufacturing have led to ever more robust CVTs, allowing them to be applied in more diverse automotive applications. As CVT development continues, costs will be reduced further, and the performance will continue to improve, making further development and application of the CVT technology desirable. This cycle of improvement will offer CVT a solid foundation in the world's automotive infrastructure. This paper aims to provide some background and relevant information that is necessary for this study. Specifically, a brief description of CVT, advantages and their brief history is presented. This paper also evaluates the current state of CVT, investigate the technology frontline of drivetrain control and the development of CVT. The stepless transmission is able to maintain the engine running at its maximum power.

Abstract

The objective of this research is to develop and test the demonstration tool of Arduino based air heater controller with Proportional Integral Derivative (PID) based control methods for the temperature range between 50ºC and 70ºC.   Arduino Uno was programmed using C-language to do control tasks and to transfer control data serially to computer via USB port. The selection of the initial PID  parameters are determined using the combination of Relay Feedback method and Ziegler-Nichols  formula.  The control methods were focused on proportional (P), proportional derivative (PD) dan Proportional Integral Derivative (PID) with the performance criteria based on overshoot  dan steady state error.  The experimental results show that the PID controllers give best output responses in terms of zero steady state errors, while P and PD controllers still result in steady state errors of about 3ºC. In addition, P controllers still give about 2,5ºC-4ºC fluctuative output values below set points, while the PD and PID have very small fluctuative values and even very close to zero. This laboratory demonstration tool has shown very good PID based controller performance, so it is feasible to be used as a supporting demonstration tool for control system laboratory in Politeknik Negeri Semarang or even other universities.

Abstract

Tuntutan kemampuan literasi bagi usia sekolah menjadi landasan Gerakan Literasi Sekolah. Berdasarkan survei yang telah dilakukan oleh Politeknik Negeri Semarang di SDN Kramas didapati bahwa permasalahan dilatarbelakangi oleh kekurangan sarana dan prasarana pendukung Gerakan Literasi Sekolah, di mana salah satu komponennya adalah perpustakaan. Pengabdian masyarakat ini bertujuan untuk membantu kegiatan Gerakan Literasi Sekolah SDN Kramas. Metode yang dilaksanakan adalah pada aspek Non ASN dengan membuat sistem informasi dan manajemen perpustakaan database berbasis IoT (Internet of Things) Library Management System. Selain itu, adalah pada aspek ASN dengan memberikan pelatihan kepada tenaga perpustakaan agar dapat mengoperasikan sistem informasi dan manajemen perpustakaan. Hasil yang dicapai adalah terimplementasinya website perpustakaan dengan nama domain perpustakaan.sdnkramas.sch.id dan keterampilan pustakawan dalam mengeola website tersebut. Integrasi sistem tersebut diharapkan dapat membuat manajemen di perpustakaan SDN Kramas menjadi lebih baik dan terkelola.
