Abstract

Vegetables are essential food for Indonesian people in their daily lives. One of them is the cabbage plant. Cabbage is one type of vegetable that is widely consumed because it contains sources of vitamins A, B, C, minerals, carbohydrates, and proteins beneficial for health. Cabbage has perishable properties, seasonal production, and can not be stored for long. Cabbage leaves are soft, and the water content is quite a lot, thus easily penetrated by agricultural tools as well as pests and pathogens. Cited from the data of the Central Statistics Agency, cabbage production in 2017 in Indonesia reached 1.44 million tons from the previous year. One factor that causes this is cabbage plant disease. One factor that causes this is cabbage plant disease. The lack of disease control information and the limited number of experts causes these problems to be resolved to the maximum. Therefore in this study, an expert system that could diagnose cabbage plant diseases based on knowledge obtained from the expert directly was built. The expert system is built based on the web using the PHP programming language and MySQL database. The inference method used is the Forward Chaining, which can diagnose the disease by adjusting the facts experienced with the rules that have been declared. This study processed 7 diseases and 24 data symptoms. Test results show that: (1) Functional testing using the Black Box Equivalence Partitioning (EP) method gets the results as expected in the test scenarios in each test class. (2) Expertise testing by comparing the results of expert diagnoses, and the system is appropriate and running well. (3) External testing using a questionnaire involving 20 respondents from the faculty of agriculture shows that the system built has a total percentage value of an average of 83% with the category "Very Good".

Abstract

Lampung University is one of the state universities in Lampung Province with a variety of faculties and departments. One of which is the Faculty of Mathematics and Natural Sciences that includes the Department of Computer Science. The Department of Computer Science applies the process of compiling lecture devices into a system. The preparation of lecture equipment cannot be separated from the tools or equipment of teaching materials because they are needed in the learning process of each subject. At this time the process of compiling teaching materials on the web-based lecture filing information system in the Department of Computer Science has not been applied using the system. Therefore, with the addition of the feature of making teaching materials in the form of handouts with the Laravel framework on a web-based lecture filing information system, it is hoped that it can assist lecturers in preparing teaching materials and assist administrators, faculty, and students in finding teaching materials so that they can be printed. The conclusion of this research is that the feature of making teaching materials in the form of handouts with the Laravel framework on a web-based lecture filing information system has been successfully added.

Abstract

Financial administration in an organization is a financial management step that starts from acceptance to how the finances used are accounted for in an objective and systematic manner. The process of searching for financial data manually takes a very long time and a large error rate. This causes the vulnerability to lose data. Especially if the financial party requires data access that is done spontaneously, it will affect the speed level. In this study, a Financial Management Information System will be built that can be utilized by the relevant Section so that all Finance in the related section can be integrated into this system. The research method used in this study uses the waterfall method. This system is built using the Laravel Framework using the PHP language. This information system was built with the aim of providing fast, precise, accurate information regarding the required data and reports.

Abstract

Waykanan pharmacy is a pharmacy that sells and has a large stock of medicines, this Waykanan pharmacy has many customers who come every day. The medicines data of this pharmacy is divided into three types of medicines, each of which includes tablets, capsules and syrups. All transactions in these pharmacies are still recorded manually, namely by recording these transactions into a book. Some of the transactions carried out included medicines sales transactions to consumers, both prescription and non-prescription sales. Information technology, especially the web, is one alternative to overcome the sale of these medicines. The purpose of this research is to produce a system that is able to record sales transactions and is able to enter medicines data and make reports. This study uses a prototype method and testing using UAT (User Acceptance Testing). The results of testing this system successfully run as it should and based on testing the level of user satisfaction on the pharmacy information system, the test results are in the good category with satisfaction levels of 79%, 77%, and 81% from each group of system admin testers, pharmacy owners and cashier. The large percentage means that the level of satisfaction of the pharmacy information system is in the very good category.

Abstract

Digiprom is a startup that provides ad serving services. These advertisements will later be shown in public places, such as supermarkets, cafes, malls, and others. The problem faced by Digiprom is that there is no information technology to help interact between Digiprom and its clients (businessman). The interactions in question are such as registration as a client, the process of making a contract between the client and Digiprom, the process of monitoring the contract that has been made and the delivery of other information about Digiprom. To solve this problem, an Android-based mobile application will be developed to help Digiprom interact with its clients. This research focuses on the development side of the Android application, while the server side is not included in this study. The development of this application will use the Waterfall method and tested using black box testing and user acceptance testing. The system design is described using three UML diagrams, namely use case diagrams, activity diagrams and class diagrams. Program code written using Kotlin language with MVVM architecture (Model, View, ViewModel). There are three main objects in this system, namely users (businessman/clients), ads (advertisements) and location (advertising locations). Each object will have its own repository. The repository has three data sources, namely network (server), Room Database, and Data Store. The use of MVVM architecture facilitates the development and maintenance process, because if there is a change in the data structure of an object, it will not affect the data structure of other objects. The results of this research (Android application) will be uploaded to the Google Play Store under the name Digiprom.

Abstract

The application of technology has an impact on replacing conventional methods with modern ones, one of which is providing document authentication. Signatures can be used as a solution in authenticating documents because they are considered capable of being used as mathematical proof that the document is not modified illegally. The difference that lies between the signature on digital documents and conventional documents is in terms of security. Signatures on conventional documents are prone to forgery. This is due to the absence of evidence to ensure that the document has been signed by the party concerned. Thus, the use of signatures on digital documents is more secure than on conventional documents. The security that is carried out to ensure its authenticity is by utilizing a QR code which contains an id, photo of the signatory which is encoded first using base-64 coding, and a link which is used to verify the authenticity of the document. The verification process carried out to ensure its authenticity is by scanning the QR code embedded in the document. The library developed using Javascript and Waterfall is used as a development method, and the testing method used is black-box testing.
