Abstract

A tourist destination is a geographical area within one or more administrative areas in which there are tourist attractions, public facilities, tourism facilities, accessibility, and communities that are interrelated and complement the realization of tourism. A website is a form of communication media that can provide certain information, which can be accessed by many people anytime and anywhere. The Regional Government (pemda) of Pekanbaru City has provided tourism information services in the form of tourist destinations and tourism activities on the website. Based on the results of preliminary observations made on the tourism website of the Pekanbaru City government, it was found that the tourism information provided was not up to date, and there were still many tourist objects in Pekanbaru that had not been published, so the information delivery process was not optimal and ineffective. The effectiveness of using the website must pay attention to usability of its use. Usability is a quality level of a system that is easy to learn, easy to use, and encourages users to use the system as a tool in completing tasks. Usability can be measured based on the quality of the user experience when interacting with the system operated by the user himself. Usability measurement on this tourism website is carried out using the System Usability Scale (SUS) measurement tool. Based on the measurement results using SUS, a score of 65.87 was obtained, where 10 of the statement items were declared valid and reliable. The score obtained shows that in terms of user satisfaction, it is stated to be included in the Marginal High category, predicate D with the adjective range Ok. This shows that the user's subjective assessment illustrates that the Pekanbaru City government's tourism website is less effective, efficient, and satisfying for users.

Abstract

Deep learning models are more often used in the medical field as a result of the rapid development of machine learning, graphics processing technologies, and accessibility of medical imaging data. The convolutional neural network (CNN)-based design, adopted by the medical imaging community to assist doctors in identifying the disease, has exacerbated this situation. This research uses a qualitative methodology. The information used in this study, which explores the ideas of deep learning and convolutional neural networks (CNN), taken from publications or papers on artificial intelligent (AI) Convolutional neural networks has been used in recent years for the analysis of medical image data. CNN's development of its machine learning roots is traced in this study. We also provide a brief mathematical description of CNN as well as the pre-processing process required for medical images before inserting them into CNN. Using CNN in many medical domains, including classification, segmentation, detection, and localization, we evaluate relevant research in the field of medical imaging analysis. It can be concluded that CNN's deep learning view of medical imaging is very helpful for medical parties in their work

Abstract

In the current era of globalization, technology is advancing rapidly, and computers are one of the technologies which are one of the tools used to make it easier to find problems, of course, it is also supported by hardware, software and brainware. Mobile stores require an information system that supports and provides satisfactory service to buyers. For this reason, the author makes this final project regarding the program for selling cellphones at the cellphone store which currently does not use a computerized system. The system at the cellphone store usually still uses a manual system. Starting from recording sales notes to bookkeeping sales reports that are still recorded in the books. This can allow for errors in recording, ineffectiveness and inefficient calculations in large numbers. And can cause inaccurate reports made. The use of the program is one solution to solving sales problems in the cellphone store. Therefore, with the use of a sales program, it is possible to further assist sales activities in the cellphone store.

Abstract

In this study, biodegradable materials that could be utilized to reduce noise were examined. Sound absorption test was conducted with an impedance tube. Sawdust, coconut fiber, and expansive clay were used to create test samples. Noise reduction coefficient results for sawdust and expansive clay mixture ranged from 0.24 to 0.62. A mixture of coconut fiber and expansive clay recorded in noise reduction coefficient between 0.31 and 0.58. Coconut fiber mixed with expansive clay recorded noise reduction coefficient ranging from 0.31 to 0.58. The study findings suggests that these materials have good acoustic properties and can therefore be used as alternative noise reduction materials. These findings have important implications in reducing environmental pollution if adopted in the development of noise reducing materials.

Abstract

Associated gas is a viable source of fuel for industrial gas turbines. Flaring of this fuel resource has not only resulted in environmental pollution and deterioration but also huge energy and economic loss. TURBOMATCH, a Cranfield University performance simulation software was used in modeling a hypothetical but realistic 296MW reheat gas turbine engine.The study was carried out using one clean fleet and three degraded fleets – the optimistic, medium, and pessimistic. Optimization of the fleet compositions and thermal efficiencies were achieved using Genetic algorithm. Detailed operations and maintenance costs analysis for the various fleets were carried out. .Results from the optimization show the optimized fleet compositions, from the various fleets and their turbine entry temperatures for 20 years life span of the project. the result from the 11th to the 20th year of the project, only one unit of engine was left due to engine divestment. Results of the optimized efficiencies for all the fleets show a gradual reduction in optimized efficiencies over the years of the project. Similarly, for all the scenarios considered, from the 11th to the 20th year of the project, with only one unit of engine left, the optimized efficiency trend is observed to be Clean > Optimistic > Medium > Pessimistic.Results from the fleets operations and maintenance costs show that the clean, optimistic, medium, and pessimistic degraded fleets have total operations and maintenance costs to be 1.224, 1.242, 1.265, and 1.297 billion US dollars respectively. Engine degradation resulted to 1.4%, 3.3%, and 5.9% increase in the operations and maintenance costs of the optimistic, medium, and pessimistic degraded fleets respectively.The results, approach and methodology presented in this paper would be a very useful decision-making tool for investors and governments who would want to invest in the economic utilization of associated gas using gas turbines.

Abstract

This study aimed to look at madrasah's efforts in developing a learning system through "digital learning." This was done by examining the digital learning system implemented at MAN in terms of its advantages and disadvantages. The method used in this research was descriptive qualitative, with the data collection techniques employed were direct observation and interviews. Meanwhile, the research location is four MAN in Jakarta and Tangerang area, including. The four madrasahs that became the research locations were MAN Insan Cendekia Serpong (South Tangerang), MAN 1 Tangerang, MAN 4 Jakarta, and MAN 13 Jakarta. The researcher conducted interviews with school parties, namely teachers and principals. The results showed that three madrasahs have well-managed e-learning systems. In this case, they are MAN IC Serpong, MAN 1 Tangerang, and MAN 4 Jakarta. The e-learning system used by each madrasah is E-Learning Madrasah which can be accessed using the web and applications from Play Store. Meanwhile, MAN 13 Jakarta still needs to have its e-learning system and use standard features such as zoom, G-meet, etc. Basically. Madrasahs such as MAN IC Serpong, MAN 4 Jakarta, and MAN 1 Tangerang have registered to utilize the digital learning platform with all the features provided. Meanwhile, MAN 13 Jakarta has yet to register, so it cannot utilize the features contained in the digital learning platform. This research implies that madrasahs have innovated well in digital learning implementation so that learning during the pandemic can run well and smoothly. This research further contributes theoretically and practically to the world of education, especially for madrasas regarded as "second-class" schools. In general, this research contributes to the development of the world of digital learning by providing a valuable platform through the various features provided

Abstract

The polyurethane foam material is commonly used and marketed in two forms, namely flexible and rigid. Flexible foam is used as a cushion, with various applications for commercial products such as chair support. Therefore, this study aims to describe the occurrence of a fire situation in a university room filled with many polyurethane foam chairs. It also aims to provide awareness regarding potential flame hazards, by using a fire modelling method with FDS. The results showed that fires on PU foam materials produced a high HRR and a wide spread of flame and smoke. From this context, the harmful effects of the fire on the room occupants were emphasized. The results obtained are expected to support the theory of compartment fire, flame distribution in solid materials, PU Foam inferno behaviour, etc. It is also expected to provide additional fire protection and evacuation training for room occupants.
