Abstract

Pengambilan keputusan harus dilakukan berdasarkan pertimbangan-pertimbangan tertentu agar keputusan yang diambil dapat bersifat objektif, karena pengambilan keputusan yang dilakukan tanpa pertimbangan yang benar dapat mengakibatkan keputusan yang diambil menjadi kurang objektif. Logika fuzzy merupakan salah satu metode untuk melakukan analisis sistem yang mengandung ketidakpastian. Pada penelitian ini digunakan metode mamdani dengan fungsi implikasi Min dan Prod dan defuzzifikasi dilakukan dengan menggunakan metode centroid. Dari analisis yang telah dilakukan maka didapatkan output dengan fungsi implikasi Max-Prod lebih besar dibanding Max-Min, maka sebelum menyelesaikan suatu kasus seharusnya dilakukan pertimbangan terhadap pemilihan fungsi implikasi yang sesuai.Decision-making should be performed based on the certain considerations in order to obtain objective decisions since the decision made without proper consideration can lead to less objective. Fuzzy logic is one of the methods for analyzing systems that contain uncertainty. In this reserch, we use implication functions Min and Prod in Mamdani method and defuzzifikasi performed by using the centroid method. From the earlier analysis done, we obtained the final results of Max-Min and Max-Prod where the Max-Prod implication functions manually produces the greater value than Max-Min, then before completing a case consideration should be done to the selection of an appropriate implication function.

Abstract

Inventories of school goods are state-owned goods, either purchased or obtained through government funds on the basis of the imposition of taxes (DPP) or obtained as exchanges or grants as well as making their own to support the smooth teaching and learning process. PABAKU Stabat Vocational School is one of the Educational Institutions in the Stabat area that has an inventory of school goods, the principal is responsible for all access that occurs in schools regarding school inventory items. At SMK PABAKU Stabat, the processing of school inventory items is still done manually by recording books and stored in archive form. This manual recording and storage of data allows for errors in the process of recording goods data, such as; data loss, repeated logging, data retrieval that requires a longer time span. In overcoming this, the author wants to assist employees in making reports through an inventory information system that has been computerized and connected to the internet using the My SQL database.

Abstract

on the process, processed rice not only produces rice, but also produces several forms of waste such as husk ash, bran, and rice bran. Rice husk ash is a hard layer that includes kariopsis which consists of two halves called lemma and palea which are interconnected. From the remnants of the rice mill, it can also be used optimally as animal feed. Feed is a mixture of various kinds of organic materials given to livestock to meet the needs of nutrients needed for growth, development and reproduction. The problem faced by this team is how to determine animal feed from the rest of the rice mill. Based on these problems, the authors designed an application system that was built using Matlab software which combines fuzzy logic programs and Matlab GUI as the application display.

Abstract

The research is based on the importance of a monitoring system for students who study outside the classroom which is very necessary on an ongoing basis, considering that the PT and DPL coordinators must continue to monitor directly or indirectly students who participate in MBKM activities. The problem so far has been the difference between the MBKM plan and the MBKM results, where from the monitoring results, there are several weaknesses in the information and data in the MBKM program, for example, difficulty in knowing the location. This study aims to design a location-based student activity monitoring system to make it easier for PT and DPL coordinators to find out student activities and make assessments based on the history of activities outside the classroom with the MBKM program followed by students. The activity history reported each day will be processed using the Term Frequency-Inverse Document Frequency (TF-IDF) method to find similarities in activities based on the completion time and types of activities carried out by students. The results of the activity history processed with TF-IDF are in the form of reports which will later become supporting information for objective assessment of student learning outcomes. The system design method used in this study is the Web Development Life Cycle (WDLC). The design stages in WDLC start from Planning, Analysis, Design and Development, Testing and Implementation and Maintenance. On the backend side for data management and reporting, a web-based system will be built with the PHP programming language using the YII2 PHP Framework. On the frontend side used by students is a mobile-based application (android) which will be built using the Ionic Framework. Data storage media uses MariaDB. The results of this study are a system that allows for monitoring students who study outside the classroom, especially students who participate in MBKM activities based on the history of activities reported at any time. Given the rapid development of technology and information today, the author suggests that it is necessary to develop the system, especially in terms of user interface, system availability in the form of applications (Android and iOS), and also increasing security, especially in terms of reading the location of student activities. The results of the test with the query Introduction to the environment, a visit to the village head's office to discuss future work programs obtained the results of the similarity level in Salsabilah Yahnun Fadila (21040203) which is 1%, Juliana Br Harianja (21040210) which is 0.7164%, Agung Dermansyah Nainggolan (21040257) which is 0.5978%, Lisman Buulolo (22090041) which is 0.4004% and Irwan Jaya Bawamenewi (21100251) which is 0.3645%. The time needed for this classification is 2.2471 minutes. For testing with the query Participating in community service activities/mutual cooperation, the results of the similarity level in Kristina Tutiniwati Ndruru (21100187) were 0.6111%, Alviusman Harita (21040253) was 0.5593%, Friska Sariaman Manalu (22070012) was 0.4735%. The time required for this classification was 1.2344 minutes.

Abstract

Early childhood education (PAUD) has a very important role in the formation of children's character, because at this age, which is called the golden age, a child's abilities can still be directed and responsive in accepting and responding to their surroundings. Financial education needs to be introduced as early as possible so that children have the right knowledge to manage money well. The habit of saving in a piggy bank is also almost never found in this digital era. The implementation of Community Service activities by the Indonesian Institute of Technology (ITB Indonesia) Kabanjahe Branch campus entitled, "The Role of Financial Education Through Fairy Tales and Enjoying Saving in Piggy Banks (Case Study: Starkids Kabanjahe Integrated PAUD School)", aims to instill the importance of financial education from an early age. The method of implementing this community service is through fairy tales and saving in piggy banks to children at Starkids Kabanjahe Integrated PAUD. The results that can be achieved from the implementation of this community service are that all children at Starkids Kabanjahe Integrated PAUD feel enthusiastic and motivated to save in piggy banks and can understand the meaning of saving.
