Abstract

This study proposes a hybrid method to classify and estimate the location of short circuit disturbance on power transmission lines. The hybrid method uses Discrete Wavelet Transform (DWT) and Adaptive Neuro-Fuzzy Inference System (ANFIS). The transmission system is implemented in a real system, in which the electric power transmission system on the KP bus to the GS bus is with a length of 64 Km. The DWT is used to process information from each phase voltage and current transient signal as well as the zero-sequence current for one cycle after the disturbance has started. The ANFIS classification is designed to detect disturbance on each phase and ground in determining the type of short circuit disturbance. ANFIS estimation is used to measure the location of disturbance that occur on the transmission line. The training and testing data are generated by simulating the types of short circuit disturbance using software with variations in disturbance location and fault resistance. The result is that the disturbance classification is with 100% accuracy and the estimated disturbance location is with the lowest error of 0.0006% and the highest error is 0.03%.

Abstract

Orthotics are the body support devices used for correction, immobilization, fixation, and prevention of paralysis. The greatest number of orthotics utilized by people suffering from plantarflexion and dorsiflexion disability, especially in Indonesia, is ankle foot orthotic (AFO). However, the duration associated with fabricating AFO through conventional methods is considered time-consuming. This paper aims to fabricate ankle foot orthotics (AFO) using innovative combinations of 3D scanning and 3D printing. The method begins with 3D scanning of the patient’s lower limb using photogrammetry (3DF Zephyr). The design is generated and adjusted, afterwards, the orthotic prototype is produced by fused deposition modeling (FDM) 3D printing using polypropylene (PP) material. This choice is attributed to the material's advantages, such as being lightweight, rigid, durable, and cost-effective. The 3D mesh model scanned using 3DF Zephyr shows good quality and more precise results. In addition, the prototype produced using 3D printing was tested by walking based on normal gait analysis’s angle of foot and calf measurement, which shows a maximum range of motion (ROM) of 16.1˚. The proposed methods of fabricating orthotic prototypes can successfully reduce the processing time by approximately 70% compared to the conventional method.

Abstract

Berdasarkan pipeline engineering, pipa di analisa memiliki tiga kondisi yaitu kondisi instalasi, hydrotest dan kondisi operasi. Pada saat kondisi tersebut pipa bawah laut sering sekali mengalami beberapa potensi dan bahaya yang mengancam kerusakan pipa dan berakibat pada keberlangsungan proses instalasi, operasi ataupun hydrotest. Apabila hal ini terjadi, maka permasalahan ini dapat meluas pada aspek pemeliharaan dan aspek ekonomis serta lingkungan yang ada disekitarnya. Selain itu, kegagalan pipa juga dapat terjadi karena faktor alam yang berasal dari gelombang, arus dan gempa bumi yang dapat menyebabkan terjadinya scouring, land slide dan soil liquefaction. Sebelum terjadi kegagalan pipa maka perlu melakukan mitigasi yang paling tepat untuk mengurangi adanya kegagalan pipa. Hydrotest itu sendiri disini memiliki peranan yang tidak kalah penting yaitu untuk mendeteksi kebocoran pipa dengan cara menyemprotkan air kedalam pipa.

Abstract

The wudhu place is where Muslims perform ablution, washing particular parts of the body using water before performing prayer (shalat). Previous study has focused on finding the best wudhu place design for sitting positions. However, there are not many studies focusing on standardizing the wudhu place for standing position. Therefore, this paper attempts to address the gap in the research by studying the ergonomic aspect and standardizes for designing male wudhu places for standing positions using Quality Function Deployment (QFD). This includes the voice of the customer and the House of Quality. QFD is an effective design method to integrate ergonomics needs and comfort into wudhu place design, as it explicitly addresses the translation of customer requirements into engineering characteristics. This method is employed to identify the important criteria for improving the design of the wudhu place. Data is collected from existing and customer surveys of wudhu place. The objective of this study is to compare and to find the best measure for standardizing the wudhu places to enhance comfort and ergonomics. Based on the study, three main criteria have been standardized: a) the distance between the tap water from the standing position should be 74 cm to 84 cm b) the distance between two taps should be 14 cm to 17 cm c) the distance of the tap water from the wall should be 64 cm to 71 cm.

Abstract

The implementation of the Japanese 5S methodology in a small motorcycle workshop in Bogor, Indonesia, has demonstrated significant improvements in workplace organization, operational efficiency, and safety. As Indonesia continues to lead motorcycle sales in the ASEAN region, the need for well-structured and efficient workshops becomes increasingly critical. However, many small businesses still struggle with inadequate organization and risk management. By applying the 5S principles—Sort (Sisih), Set in Order (Susun), Shine (Sapu), Standardize (Standar), and Sustain (Sinambung)—the workshop experienced reduced disorder, improved workflow, enhanced cleanliness, and well-defined procedures. These changes positively impacted productivity, workplace safety, and customer perception. Initial resistance to change was mitigated through comprehensive training and staff engagement, ensuring long-term adoption. This initiative aligns with Sampoerna University’s commitment to community development and serves as a scalable model for small businesses. With adequate government and NGO support, the 5S framework can enhance efficiency, competitiveness, and working conditions in Indonesia’s expanding motorcycle industry.
