Abstract

Technological developments are very dynamic so that the information produced is fast and accurate, starting from an office to the educational level. Management of facility maintenance data at State Senior High School 2 Sijunjung is still done manually. Determining facility maintenance work based on manual management can cause the determination of facility maintenance work to be irrelevant. To overcome this problem, a decision support system is needed that can improve the process of managing and determining facility maintenance work using the Weighted Product (WP) method. The Weighted Product (WP) method is a multi-criteria decision-making method used to solve the problem of selecting the best option from several available alternatives. Based on the results of the analysis in the process of determining facility maintenance, the researcher made manual calculations using the weighted product method where there are 5 criteria and 15 alternatives. From the results of these calculations, the researcher made a decision by looking at the ranking of the WP calculation where the art room was ranked first with a value of 0.0900. This system is expected to be able to assist schools in managing facility data that affects the determination of facility maintenance work priorities and as a basis for decision-making in determining facility maintenance work

Abstract

The Inlis application at the West Sumatra Provincial Archives and Library Service is used to manage the process of borrowing and returning books carried out by each library member. With this library system, it can help librarians to find out the flow of books in and out and the delay in returns made by library members to determine the fines that must be paid by members. Based on this, the author will measure the quality of the Library Information System because in this system the level of system quality is not yet known, so as to identify the accuracy, completeness and quality of the software in the Inlis Application. The measurement method in this study is the McCall Method. The McCall Method is a software testing method that bridges the gap between users and developers that focuses on a number of software quality factors. Software quality can be interpreted as an effective process that is realized in the form of a product that can provide benefits and can be measured. The results of the study based on the McCall Method show that the quality of the Inlis Application is good with a percentage value of 72%, with the best indicator value, namely reliability with a result of 80% and the worst indicator value, namely integrity with a result of 44%.

Abstract

Farmers still do not really understand how to diagnose problems in plants, one example is strawberry farmers. This is proven by several farmers and strawberry plant cultivators, not all of whom can understand the disease where there are various types of diseases that can attack strawberry plants with almost the same symptoms , and if a farmer or cultivator is wrong in handling the type of strawberry plant disease, it is not impossible that it will cause the strawberry plant to die. Strawberry farmers need a tool to diagnose strawberry plant diseases so that they can find out the condition of the strawberry plants. Therefore, an expert system was created to diagnose diseases in strawberry plants and find solutions to deal with the damage that occurs. The system built for diagnosing diseases in strawberry plants uses the Forward Chaining method. Forward chaining is a forward tracking that starts from a set of facts by looking for rules that match the existing hypothesis towards a conclusion. In its implementation, this system has met these objectives by using a database and rule base. The system draws conclusions based on existing facts using the forward chaining method, the search starts from the facts from which new conclusions are obtained, the existing rules are traced one by one until the search is stopped because the last condition has been met.

Abstract

The increasingly rapid advancement of technology has an indirect impact on humans. Computers are one of the results of technological advances that can help humans improve the quality and quantity of work. By using computers as one of the tools in presenting data information, especially data processing supported by PHP and MySQL applications, it can support the speed of data processing as efficiently as possible. This study uses the Importance Performance Analysis (IPA) Method and the Customer Satisfaction Index (CSI) Method. The IPA method is a method used to map the relationship between interests and performance of each attribute to meet consumer satisfaction by providing a Likert scale. While the CSI method is a method used to determine the level of consumer satisfaction as a whole by looking at the level of satisfaction of product and service attributes. Based on the combination of the IPA and CSI methods carried out directly in the field using interview techniques, as well as by studying books related to the problems discussed, it is expected that the new system that will be implemented can improve the quality of information so that it can be useful for the relevant agencies. The results of this study are based on the consumer satisfaction index of 82.24% , so that by applying these two methods, it can find consumer satisfaction in increasing curtain sales.

Abstract

Kitchen seasonings are substances that generally come from aromatic plants which are added to dishes with the aim of flavoring food. Seasoning serves to make food taste better. Delicious or not a food depends on the spices added. Seasoning is made from a mixture of spices through various processing processes. Generally, cooking spices are classified into three groups, namely red, white and yellow main spices. Many types of spices can be made into seasonings, for example coriander, pepper, black pepper. There are various types of spices, so storage in the warehouse requires a place that is suitable for the types of spices. So that suppliers are not confused about storing kitchen spices and if needed they are not confused anymore. The supplier will send the spices according to consumer demand, samples in kilo sizes according to the space provided and there will be no more mistakes. This research was carried out by designing, manufacturing and implementing the process, LCD as an information display, Load Cell as a detector for spices, and speakers providing information in the form of sound covering the microcontroller controlling the process, namely the Orange Pi.

Abstract

Train accidents are one of the transportation events that often occur in Indonesia. One of the problems that surfaced is the problem of railroad crossings. Accidents that often occur around railroad crossings are caused by the negligence of gatekeepers or the attitude of undisciplined drivers. In order to reduce these accidents, it is necessary to provide automatic crossings at unguarded crossings. Meanwhile, on guarded crossings, automatic door controls are installed to reduce human error, but can still be controlled manually when needed.In addition, the installation of manual passage gates at each railroad crossing will require a large amount of manpower. And on the crossbar draft. Automatic doors that previously used ultrasonic sensors were quite effective but were still constrained by ultrasonic sensors not being able to identify what objects were in front of them. Therefore, technology is needed to reduce accident rates at railroad crossings, as well as reduce accidents caused by (human error), provide educational facilities at each railroad crossing which are useful for increasing driver awareness so as not to cross railroad crossings when the gate is closed. cover and added an alert system to minimize sensor detection errors. The technology is a passageway that operates automatically and displays an LCD and speaker as a means of information.
