A 10-MHz FREE-FREE BEAM MICROMECHANICAL RESONATOR FABRICATION PROCESS USING SURFACE-MICROMACHINED TECHNOLOGY

The fabrication process for the designed MEMS resonator using surface-micromachined technology is presented in this paper. A 10-MHz Free-Free beam MEMS resonator is designed to vibrate in the second-mode shape, which is significant improvement compare to the fundamental mode. The design showed a Q value as high as 75,000, which is significant improvement compared to 8,400 VHF F-F beam MEMS resonator by K. Wang; and very low motional resistance (18kΩ). The surface-micromachined technology is used as the standard process for the design. The process is briefly described from the layout design to the experimental fabricated device.

Survey Analysis of Enhanced Oil Recovery (EOR) Laboratory towards Featured Research Laboratory

The EOR Research Laboratory is a laboratory that was independently pioneered by the Department of Petroleum Engineering UPN "Veteran" Yogyakarta. The EOR Research Laboratory needs to be improved especially for the existing spatial layout to support the ongoing and future research. This Institutional Research will cover the planning process of spatial layout design, spatial layout realization, internal and external EOR Research Laboratory socialization, and at the end of the study, effective and efficient governance will be applied to adapt to the current pandemic conditions. The method used in this research is quantitative in the form of socialization, questionnaires, and survey analysis to find out how EOR Laboratory is well known among students. This research is expected to be able to introduce the EOR Research Laboratory in a wider range and carrying out sustainable research in the future so that it will support the planning of the laboratory to be the Leading EOR Research Laboratory at the Department of Petroleum Engineering, UPN "Veteran" Yogyakarta.

Collaborative Workplace Design: A Knowledge-Based Approach to Promote Human–Robot Collaboration and Multi-Objective Layout Optimization

The innovation-driven Industry 5.0 leads us to consider humanity in a prominent position as the center of the manufacturing field even more than Industry 4.0. This pushes us towards the hybridization of manufacturing plants promoting a full collaboration between humans and robots. However, there are currently very few workplaces where effective Human–Robot Collaboration takes place. Layout designing plays a key role in assuring safe and efficient Human–Robot Collaboration. The layout design, especially in the context of collaborative robotics, is a complex problem to face, since it is related to safety, ergonomics, and productivity aspects. In the current work, a Knowledge-Based Approach (KBA) is adopted to face the complexity of the layout design problem. The framework resulting from the KBA allows for developing a modeling paradigm that enables us to define a streamlined approach for the layout design. The proposed approach allows for placing resource within the workplace according to a defined optimization criterion, and also ensures compliance with various standards. This approach is applied to an industrial case study in order to prove its feasibility. A what-if analysis is performed by applying the proposed approach. Changing three control factors (i.e., minimum distance, robot speed, logistic space configuration) on three levels, in a Design of Experiments, 27 layout configurations of the same workplace are generated. Consequently, the inputs that most affect the layout design are identified by means of an Analysis of Variance (ANOVA). The results show that only one layout is eligible to be the best configuration, and only two out of three control factors are very significant for the designing of the HRC workplace layout. Hence, the proposed approach enables the designing of standard compliant and optimized HRC workplace layouts. Therefore, several alternatives of the layout for the same workplace can be easily generated and investigated in a systematic manner.

Website Layout Design of Kurnia Advertising as a Promotion Media in the City of Malang

Layout is the basic framework that must be built in a design work. In this Kurnia Advertising promotional website, the power of layout in displaying information is dominated by white which gives the impression of a clean and simple design. Other elements use dominant colors of yellow, black and orange which are intended to give a cheerful and elegant feel. Product photos and detailed product information are presented on the website to provide more complete information to users. The ease of accessing the website and complete information are the strengths of this website to attract consumers to be interested in buying services from Kurnia Advertising. Tests carried out by distributing google forms to measure the effectiveness of website design and content were carried out on 50 respondents. The test results show that the website is quite effective in providing information to users with a simple design. In addition, the development of a website that is used as a promotional medium aims to make it easier for users to get information through features and the addition of a complex but structured menu so that the information conveyed can be more optimal.

AN INHERENTLY SAFER LAYOUT DESIGN FOR THE LIQUEFACTION PROCESS OF AN FLNG PLANT

Floating Liquefied Natural Gas (FLNG) facilities have limited space available and a high possibility of accidents occurring. The severity of consequences requires an inherently safer layout design. Scope of the liquefaction process requires to determine the size of utilities, operating costs, the deck area and the number of LNG trains. The layout of the liquefaction process plays a key role in defining operational and economical safety of the whole FLNG plant. The present study focuses on developing a novel methodology to design an inherently and optimally safer layout for the generic multi-deck liquefaction process of an FLNG plant. The integrated inherent safety principle is applied at the early phases of the layout design considering inherent safety and cost indices in three different layout options, and for the final design the most optimal option was selected. The proven indexing approach quantified the associated risks in all units. Safety measures were undertaken to eliminate or reduce the risk to an acceptable level. The results showed that the economic losses due to domino effects were limited by an improved layout design and passive control strategies. This study only dealt with evaluation and analysis of critical units of the plant due to a lack of detailed information at the early phase of the design. However, the proposed method plays a positive role in obtaining an inherently safer layout design of any multi-deck plants.
