Abstract

Chili, mustard greens, and tomatoes have always been farmers' favored crops, despite their high water and labor demands. Adapt to these conditions by utilizing smart agriculture systems (SAS) agricultural techniques that involve technology such as automatic irrigation that regulates watering based solely on routine, regardless of land conditions. This type of control during the transitional season can lead to root rot and fungisarium disease on chile plants. In the form of an embedded system with internet of things (IoT) monitoring, a system incorporating artificial intelligence such as fuzzy logic is proposed as a solution. Fuzzy logic will regulate irrigation based on the land's humidity and temperature using computational mathematics. Beginning with the fuzzyification stage to map the sensor's temperature and humidity input values, fuzzy logic is applied. The creation of an inference engine in the NodeMcu 8266 microcontroller to interpret fuzzy rule statements in the form of aggregation of minimum conditions with the AND operator, followed by the combination of a single set value of 0 and 1 in the fuzzy system to produce an appropriate actuator response After the entire system has been prototyped, testing is conducted to determine the responsiveness of the fuzzy program code to changes in the simulated agricultural cultivation land ecosystem. This study found that the fuzzy logic program code embedded in the nodeMCU8266 microcontroller effectively controls the spraying duration of the pump in response to various simulated environmental conditions within 3.6 seconds.

Abstract

Higher Education quality assurance is a planned and sustainable process in systematically improving the quality of Higher Education. One of the functions of quality assurance for tertiary institutions is for accreditation activities, in study programs accreditation preparation is an activity that often requires time, energy and the minds of the academic community. The problem that often arises in quality assurance activities is that supporting data and information that are required for completeness have not been well documented. As time goes by, there are more and more documents and the search for documents is getting longer, because you have to open documents in every folder where these documents are not small. The purpose of this research is to overcome some of the problems that arise, including good archive management, documents can be grouped by year or criteria and time efficiency in recapitulating all quality assurance documents. The method used in the development of this system is the Rapid Application Development method, which enables faster system development.

Abstract

Indonesia, as a developing country, is not exempt from the advancements in information and communication technology. However, these advancements in information and communication technology can bring negative impacts, such as an increasing threat of misuse. SDP (Service Desk Plus) is a system that serves as a management tool for IT services, facilitating employees from various departments in requesting services and reporting ICT (Information Communication Technology) incidents. SDP has faced challenges or obstacles that have hindered its optimal use, such as IT services experiencing downtime, inaccessible ICT services, and SDP users frequently sharing usernames and passwords. Based on these threats, it is necessary to conduct a further analysis of information security risks regarding the security of implementing SDP centrally using the OCTAVE Allegro method. OCTAVE Allegro is a framework that utilizes the OCTAVE approach with a primary focus on information assets, designed to provide faster results without requiring in-depth knowledge of risk assessment. The results of this research identified three risks that can be mitigated, namely user data password errors with a relative risk score of 27, internet downtime with a relative risk score of 31, and file intrusion with a relative risk score of 38, considering the likelihood of threats occurring. Additionally, there is one accepted risk, which is the input error of incident data, with a relative risk score of 19.

Abstract

Social assistance or what is often called Bansos (Bantuan Sosial) is assistance in the form of goods or money from the government for the community that is temporary and selective. There were many reports from the public complaining that some had not received assistance or had not received it at all. This problematic social assistance has caused a stir in public reports on various social media, including Twitter. To find out the classification of public opinion related to social assistance on Twitter, it is necessary to do pre-processing and analysis of tweets. The dataset used is data crawled using the Twitter API and produces 702 tweet data in CSV format. Tweets retrieved based on the keyword 'bansos' in August 2021. The dataset is divided into two categories, positive and negative. Data with a total of 328 positive categories and 374 data of negative categories. The method applied in this study uses the Chi-Square feature selection method and the Naïve Bayes Classifier algorithm. The purpose of this research is to produce a website-based application that can classify tweets related to social assistance covid-19 into 2 categories, positive and negative by using the Chi-Square feature selection and the Naïve Bayes Classifier algorithm. The F1 score in the positive class is 85% and the negative class is 89% and produces an accuracy value of 87%. The results of the comparison between Naive Bayes and Naive Bayes using Chi-Square show that there is no difference in accuracy.

Abstract

The Padrepio Helvetia Medan Parish Mandiri Savings and Loans Association Cooperative is one of the cooperatives engaged in the savings and loan sector by prioritizing members' desire to save so that they can create joint capital for members to borrow with appropriate loan services for welfare purposes. The Annual Members' Meeting is an annual agenda as a media for management to be accountable for their performance for one year. The chairman of the cooperative is the highest structural position of the administrator who has duties and responsibilities both inside and outside the cooperative in controlling all cooperative activities. The process of electing the chairman of the Padre Pio Parish Savings and Loans Association cooperative is still being carried out only by pointing to and mentioning someone's name from among the names of the management and then conveying it to members to approve. The determination of the chairman which is carried out using the arbitrary model is not in accordance with the terms and criteria of an optimal cooperative chairman because the elected chairman is not necessarily the most competent of the candidates and often happens just because of friendship so the results are not objective. With the reasons described, the researcher applied the MOORA method. The application of the MOORA method to the election of the chairman of the Padre Pio Helvetia Medan Parish Independent Savings and Loans cooperative can help determine a more objective chairman based on terms and criteria by solving problems through complex mathematical calculations, determining the weight value for each attribute, then proceed with the ranking process which will select the alternative that has been given. In this study the criteria determined consisted of background and educational level, certificate ownership, age, and length of time being a member. In the objective approach, the weight value is calculated mathematically so that it ignores the subjectivity of the decision maker. With the application of the MOORA method, several alternatives that meet the requirements and criteria can be determined which is the best to serve as chairman. The best ranking results are those who are most worthy of being the head of a more objective cooperative.

Abstract

Indonesia has an important role as a country that produces various high-quality culinary items. Indonesia, with its plethora of natural resources and cultural diversity, can generate a wide range of culinary goods, including traditional foods and beverages as well as modern culinary inventions. Natural and cultural potentials are the foundation for the development of exceptional food and beverages in a country manufacturing culinary products. However, numerous issues with marketing are not global enough, even though Indonesian culinary items should be able to compete with well-known food products. Information technology and the internet have altered the culinary business scene in Indonesia, making it easier for local culinary products to obtain worldwide market share. This article investigates how the existence of information technology and the internet has opened up new avenues for Indonesian culinary manufacturers to broaden their marketing reach. Indonesian culinary items can now be accessed by consumers worldwide via an online platform, removing geographical barriers and presenting substantial economic growth possibilities. This study created an application system to advertise culinary products, with the first steps focusing on designing application systems. The Unified Modeling Language technique is used to create the culinary application system. This procedure aids in visualizing the system's structure, and interactions deployment. As a result, development teams and stakeholders have a more structured design and a better grasp of the system. Unified Modeling Language is quickly becoming a valuable tool for supporting thorough collaboration and documentation in application development.

Abstract

Tourist attractions are very interesting things to visit in an area that we are living. It is no exception when visiting the city of Medan, the tourists will visit interesting tourist spots in the city of Medan. To optimize time so that you can visit all tourist attractions in Medan City, you need to map locations so that you can create the shortest route that can be used to take all the tourist sites you want to visit in Medan City. The shortest route of a trip will shorten the travel time. Likewise in terms of seeking experts. When requesting a route from one point (start point) to another location (destination point), usually the result that comes out is the "shortest path" from the starting point to the destination point. The shortest path is the problem of finding a path between two or more vertices in a minimum weighted graph. To simplify solving the shortest path problem, a search algorithm is needed. Dijkstra's algorithm solves the problem of finding the shortest path between two vertices in a weighted graph with the smallest total number, by finding the shortest distance between the initial vertex and other vertices, so that the path formed from the initial vertex to the destination vertex has the smallest total weight. In this study, Dijkstra's algorithm looks for the shortest path based on the smallest weight from one point to another, so that it can help provide a choice of paths. Based on the trials of Dijkstra's algorithm, it has the ability to find the shortest path, because in this algorithm each graph is selected an edge with a minimum weight that connects the selected vertices with other unselected vertices.
