Abstract

Information technology has been used by all aspects of life and has become an inseparable part of all community activities, especially in the business world. Currently, marketing and product promotion activities are still using banners and social media and reporting activities are still being done manually. This causes a waste of promotional costs and the accuracy of the report data may not be in line with changes in existing data. For this reason, an electronic sales information system (E-Commerce) was designed using the Rapid Application Development (RAD) method using the PHP programming language and MYSQL database. The program designed will produce an E-Commerce sales system that will help the sales system run, as well as a clear bookkeeping report to the leadership. With this new system, it is hoped that there will be changes in sales governance and reporting for the better.

Abstract

In today's human life, both at home and in industry, it is very necessary to have LPG gas to meet daily needs. We know that gas can also have a bad impact, especially if there is no known leak from the LPG gas cylinder or storage area. The cause of this gas cylinder leak could be a leak in the hose, tube or also the regulator that is not installed properly and the gas cylinders that are distributed are of poor quality or physically damaged. This study aims to produce a tool that is an LPG gas cylinder leak alarm using the MQ-2 sensor. The way this tool works is, the Arduino UNO reads the MQ-2 sensor with analog data output, if it reads that there is gas leaking, the alarm will sound.

Abstract

Processing of coconut shells into charcoal powder as a concrete mixture. The use of coconut shell charcoal powder on the compressive strength of concrete aims to be a substitute for cement for normal concrete compressive strength and to determine the optimum concrete compressive strength after substitution of cement using coconut shell charcoal powder. In this study the use of coconut shell charcoal powder as a cement substitution with variations of 0%, 2.5%, 5% and 7.5%. Concrete testing was carried out at the age of 28 days after treatment by being immersed in water. The results of the analysis showed that the average compressive strength value of the addition of coconut shell charcoal powder at variations of 5% and 7.5% decreased by 11% and 12.57% because with the increasing number of calcium hydroxide formed, the cement adhesion will decrease so that the structure inside will be weak and cause the compressive strength to be low, while the variation of adding coconut shell charcoal powder 2.5% has an increase of 2.07% against normal concrete compressive strength. From the results of the characteristic concrete compressive strength obtained with substitution variations of 2.5%, 5%, and 7.5% respectively of 278.74 kg/cm2, 243.43 kg/cm2 and 238.96 kg/cm2, the concrete These include class II K 275 concrete (middle class concrete) structural concrete.

Abstract

Diabetes mellitus is a disease characterized by high blood sugar (glucose) levels. DM is known as the silent killer because the sufferer is not aware of it and is identified when complications has already occured.Complications experienced by patients at the Sambit District Health Center were based on the results of interviews. 20% of patients at the Sambit District Health Center suffered from complications. This increasing number is due to delays in diagnosis and unhealthy lifestyles as well as a lack of information so that many patients are diagnosed after complications occured. Early diagnosis will reduce the risk of complications. From this point, an expert system is needed as a diagnostic tool whether the patient suffers from diabetes mellitus or not. Based on this problem, the Naive Bayes algorithm is chosen because it is based on classification by comparing old data and new data, and from this problem the compiler classifies a person who suffers from Diabetes Mellitus with those who are not at the level of symptoms suffered by looking at the events that have passed. From the results of tests that have been carried out from 20 patient data, the percentage of accuracy of the system is 100% (based on facts and symptoms). From this study, it can be concluded that diabetes mellitus is a dangerous disease and still requires early prevention.

Abstract

Websites have a very important role because they provide various information. Websites are useful to make it easier for someone to find information, ranging from obsolete to the latest information. Websites provide information that is up to date and currently being discussed. Therefore, we need a system to make it easier to provide information to readers. The system created is designed by using Agile where this methods is used for software development in the sort term. In addition, there is a method for sorting the most viewed data by using the MFEP ( Multifactoring Evaluation Process ) method. This research can help information providers in providing information to readers quickly, well and in a more structured manner.

Abstract

cylinder head is a part that is exposed to thermal and mechanical loads which not only affect engine performance parameters. The purpose of this study is to analyze the failure of the cylinder head structure of a 4 stroke diesel engine and find the cause of the failure. In this study, surveys and measurements of the cylinder head were carried out, to find out the appropriate results so that they could determine cracks, wear, and warping of the cylinder head. The results showed that the maximum bend on the side of the cylinder head attached to the cylinder block was 0.07 mm, 0.08 mm, 0.069mm. While the maximum bending on the side of the cylinder head attached to the manifold is 0.15 mm, 0.14 mm, 0.16 mm. At maximum bending on the side of the cylinder head attached to the exhaust manifold, it is necessary to pay attention to how to use the diesel engine correctly and according to operating hours.

Abstract

Berau Regency is an administrative area in East Kalimantan Province. Berau Regency has been named the area with the most and most beautiful tourist attractions in East Kalimantan, both in terms of culinary, culture, customs, and even natural tourism. Of course this becomes a deja vu if there is no special tourism information system to determine decisions for choosing tourist attractions based on tourist backgrounds.In science there is a system called Fuzzy Multi Attribute Dicision Making (FMADM) or commonly known as; with Simple Additive Weighting (SAW). This system can be an option to get a solution for the selection of tourist attractions in Berau Regency. With this support system, it is hoped that it can help the Berau Regency Government in managing tourism in Berau Regency.In the decision to choose tourist attractions, it is necessary to classify the criteria needed by tourists as well as similar tourism alternatives. With the Fuzzy SAW method, it is expected to be able to help tourists to get information and recommendations for the desired tourist attractions in Berau Regency.The system of this method is useful for processing data on tourist criteria, until finally producing a recommendation of the expected tourist attractions. It is also hoped that this Decision Support System can help the Berau Regency Government, especially the Berau Regency Tourism and Culture Office.

Abstract

As we all know, the world of technology and information has become very advanced in recent years. This has led to numerous new ideas that make it easier for a person or organization to do their work and achieve their goals. Progress in technology and information greatly affects all areas, from culture and education to the economy, health, and even beauty. So, in this study, the researcher brought up a problem at a beauty clinic in Maguwoharjo, DIY, called Emila Aesthetic Solution. The problem is that consulting with patients is still done face-to-face. In other words, the clinic does not have a computerized system to help with consultations so that patients do not have to wait in line and can get treatment right away based on the results of their consultation. As a result, this study focused on developing an expert system to diagnose skin problems using the naïve Bayes classifier method.In this study, the system was made using the naïve Bayes classifier and the waterfall model for system development. The model was then coded into the system to be used. The goal of making this expert system was to make it easier for patients to get advice and for the clinic to handle patients.Based on the patient history data obtained, namely 20 patient data that experts have tested, this expert system, by implementing the naïve Bayes classifier method, yielded results indicating that the system's accuracy was 100 percent.

Abstract

Depressive disorder in the elderly is a clinical and public health issue that has yet to be addressed. The elderly who live at home with their families have better physical, psychological, and environmental health than those who live in orphanages. Mental health issues, particularly depression, frequently go undiagnosed in the elderly. This is because older people who are depressed often have physical symptoms like insomnia, loss of appetite, stomach problems, and headaches. When older people are depressed, their bodies tend to hurt more. It is hard to tell whether someone is complaining about their body or mind, so depression is often found too late. To anticipate these issues, an expert system was created that can take the place of an expert in solving the problem. A clinical psychologist is an expert in the field of elderly depression. This study classified elderly depression into three levels: mild depression, moderate depression, and major depression. This study was carried out with the help of a case study from the Tresna Werdha Pakem Social Center in Sleman, DI Yogyakarta.The Certainty Factor method was used to make an expert system for determining how depressed an older person is. This is because it is a sure thing based on evidence or an expert's opinion. The goal of developing an expert system for diagnosing depression in the elderly is for expert and non-expert officers to diagnose the level of depression in the elderly. Based on 10 elderly data that the system and experts have tested by applying the Certainty Factor method, the accuracy was 98%.
