Abstract

Methyl ester is considered one of the alternative substitutes to mineral oil as an insulating liquid. This study investigates the dissolved gas analysis (DGA) of the methyl ester derived from palm oil, under low energy discharge faults. The aims are to understand the gas composition and evaluate the applicability of the well-established fault interpretation methods for mineral oil to the methyl ester. Experimental procedures were conducted based on the International Electrotechnical Commission (IEC) standards. It involved simulating electrical breakdowns in laboratory conditions as per IEC-156 standard and analyzing gas samples using gas chromatography based on IEC-567. Results show that methyl ester oils produce similar types of gases as mineral oils but at higher concentrations. The interpretation of DGA results using fault identification methods such as Duval Triangle, Duval Pentagon, and IEC ratio indicates an overestimation of fault severity in methyl ester oils, and categorizing the faults as high energy discharge. However, the key gas method correctly identifies the discharge in both methyl ester and mineral oils. These findings suggest the need for adjustments in existing DGA methods to account for the higher gas concentrations in methyl ester oils, for effective condition monitoring and maintenance of transformers if it was filled with methyl ester oil.

Abstract

Pada kanal komunikasi, sinyal informasi yang dikirimkan akan selalu mengalami gangguan karena adanya derau yang menyebabkan terjadinya kesalahan pendeteksian sinyal sehingga terjadi perubahan bit atau simbol pada sisi penerima. Hal ini menyebabkan konstelasi sinyal di sisi penerima tidak sama dengan konstelasi sinyal di sisi pengirim. Pada penelitian ini diteliti pengaruh derau AWGN pada sinyal yang dikirim. Untuk itu akan dibuat suatu pemodelan, simulasi dan analisis untuk mengamati pengaruh derau AWGN terhadap unjuk kerja sistem modulasi 16 QAM. Unjuk kerja tersebut dapat diketahui dari nilai Bit Error Rate (BER). Penelitian menunjukkan bahwa adanya derau mempengaruhi unjuk kerja dari sistem komunikasi.

Abstract

Community activities aim to design and implement an automatic etching machine using a microcontroller and servo motor. The microcontroller acts as the control unit, regulating the movement of the servo motor to ensure the etching process runs with maximum efficiency. The method used in this activity is divided into several structured stages. The first stage is design, where the device is designed using a microcontroller to control the servo motor responsible for moving the PCB undergoing the etching process. The second stage is implementation, where the components to be used include the microcontroller, servo motor, LCD, buttons, and etching container. The final stage is evaluation, where the created device is assessed based on the suitability of the motor movements produced according to the main objective, which is to produce tracks as desired by the operator. The results of implementing this automatic etching machine activity are expected to provide several key benefits. Firstly, the machine can reduce the time required to complete the PCB etching process, thereby increasing productivity in PCB printing services. Additionally, by reducing human involvement in the monotonous physical process, this machine helps avoid human errors and thus can improve the quality of the products produced.

Abstract

Applying science and technology encourages innovation, increasing development productivity, independence and national competitiveness. Indonesia has a science and technology area named Science Techno Park (STP). Maturity measurement is an indicator of the level of an STP to apply science and technology for the welfare of society. There are three levels of maturity for STP, which are low (pratama), middle (madya), and high (utama). Before entering the best maturity level, STP must go through various kinds of preparation and fulfil the elements contained in it. The community service activity team at Universitas Andalas conducted a web seminar (webinar) to socialise the maturity assessment for STP Unand from the academic side. The webinar invited two experts on STP maturity measurement. One of the primary assessments is the number of products produced that are expected to come from the results of academic research. This activity can help STP Unand prepare to increase its maturity to a high level.
