Abstract

Misalkan K suatu lapangan, A = KE adalah suatu aljabar lintasan yang bersesuaian dengan suatu graf berarah E. Aljabar lintasan A disebut Nakayama jika aljabar bersifat basic dan terhubung dari graf (graf berarah) EA, dimana setiap titik menjadi sumber dan target paling banyak satu panah. Tulisan ini membahas modul prima dan modul herediter atas aljabar Nakayama tertentu. Modul prima atas aljabar Nakayama dari graf tipe An hanyalah modul sederhana. Selanjutnya, untuk aljabar Nakayama dengan graf berbentuk garis, semua modul projektifnya merupakan modul herediter, sedangkan untuk aljabar Nakayama self-injective, semua modul projektifnya bukan modul herediter.Kata Kunci: Graf, Aljabar Lintasan, Aljabar Nakayama, Modul Prima, Modul Herediter

Abstract

Pandemi Covid-19 berdampak pada dunia pendidikan. Proses pendidikan yang awalnya dilakukan secara tatap muka telah bergeser menjadi pembelajaran daring. Hal ini menyebabkan siswa merasakan penurunan kemampuan belajarnya terutama dalam hal literasi. Siswa yang baru mulai belajar membaca di sekolah dasar dianjurkan untuk belajar di rumah secara daring bersama orang tuanya. Penelitian ini bertujuan untuk menganalisis kategori kemampuan literasi siswa di SD Negeri 21 Pasir Tinggi, Kabupaten Agam. Orang tua siswa yang sebagian besar adalah karyawan PT AMP bekerja dari pukul 08.00 hingga 17.00 WIB, sehingga tidak bisa mendampingi siswanya saat belajar daring di rumah. 2 dari 10 orang tua/wali siswa juga menderita buta huruf. Pada malam hari, orang tua memilih untuk melakukan kegiatan lain untuk menambah penghasilan. Hal ini mengakibatkan sangat sedikitnya dukungan orang tua terhadap anak dalam kegiatan belajar. Akses internet juga menjadi pemicu keberhasilan e-learning, namun SD Negeri 21 wilayah Pasir Tinggi, merupakan salah satu daerah terpencil yang jaringan internetnya sulit. Oleh karena itu, untuk mencapai tujuan penelitian ini, teknik pengumpulan data dilakukan melalui tes yang penulis amati pada tabel “Reading Observation Checklist”. Data penelitian yang diperlukan diambil dari seluruh siswa SD Negeri 21 Pasir Tinggi yang berjumlah 31 siswa dengan memperhatikan perilaku membaca siswa dalam 10 kali pertemuan. Hasil analisis kemampuan siswa menunjukkan bahwa 55% dari seluruh siswa di SD Negeri 21 Pasir Tinggi tidak menguasai membaca, sehingga sulit menerapkan pembelajaran sesuai tingkatannya.

Abstract

Timely graduation of students is essential for determining the quality of college. Universities must know the percentage of students' ability to complete their studies on time. So, to deal with this problem, data mining classification is carried out to predict student graduation on time to find patterns for student on-time graduation predictions. This research can yield new information to help colleges anticipate student graduations that are not on time. The method used is a classification data mining method with 4 algorithms: naïve Bayes, random forest, support vector machine (SVM), and artificial neural network (ANN). The attributes used are gender, parental income, length of guidance, working student status or not, semester 1 to semester 8 grades, and GPA. This study used Python 3 programming language on jupyter notebooks in Anaconda to process datasets. The distribution of datasets is divided by 70% for training data and 30% for testing data. The results of this study were obtained with the best algorithm accuracy in the support vector machine (SVM) algorithm is 0.94. Based on the results of this study, the accuracy is good for predicting student graduation on time.

Abstract

This article deals with two topics, namely the hereditary property of path algebras and the hereditary property of Leavitt path algebras. The hereditary property is advantageous in studying projective modules over algebras. In the first topic, the path algebras are hereditary if the graph is finite, connected, and acyclic. In the second topic, Leavitt path algebras are hereditary if the graph is finite

Abstract

One of the research objectives was formulated to improve the quality of education, namely by understanding the problems of students and teachers. There were three main groups of quality characteristics of education highlighted in scientific and academic literature in Russia, namely the quality of educational objectives, the quality of the educational process, and the quality of educational outcomes. The problem of education in Indonesia is the quality of the education process. The development of teaching materials is an alternative to improve the quality of the education process. Research so far has only focused on the implementation of learning models by teachers in the classroom, but the model is not integrated into the teaching materials used. This paper examines how the effectiveness of a product that has been developed for two years on 27 Indonesian students. The product produced is a guided discovery-based module in the Complex Analysis subject. This product was developed after the preliminary analysis (defining) process. Students are given 16 modules during lectures; then students are given a final test containing all the competencies that must be achieved. Test results are scored, and statistical analyses are conducted to compare them with student score before using the module. The test used is t-test. The design used is one of the experimental research designs, One Shot Case Study. The results of the study showed that students who were taught with modules developed effectively to improve student learning outcomes. Further research can be done by implementing different learning models in teaching materials.

Abstract

PRL Rajo Tigo Selo Farmer Group is a community service partner of Bukittinggi Prima Nusantara University in 2024. The partner is an environmentally friendly farmer group located in Jorong Babukik, Nagari Kamang Mudiak, Agam Regency, with 21 group members. These partners are divided into three divisions: the Agriculture Division, the Livestock Division, and the Agricultural and Livestock Products Processing Division. PRL Rajo Tigo Selo has been involved in agriculture and livestock since the establishment of this farmer group. The problem faced by the partners is the lack of innovation in processing agricultural and livestock products. Well-packaged products are not only attractive to consumers but also meet hygiene and food safety standards. This innovative food processing product is being applied through packaging technology activities to several micro, small, and medium enterprise products belonging to farmer groups, such as galo-galo honey, roasted salted eggs, vegetable nuggets, and green lado duck. The packaging technology using a vacuum sealer and sterilisation tools can extend the shelf life and resistance of products to microbiological damage. Based on this, the community service team conducted training on packaging technologies for farmer group members and UMKM stakeholders in Jorong Babukik to increase the competitiveness of local products. The results of this community empowerment are being used as the main source of stunting prevention in Jorong Babukik, Kamang Mudiak, Agam Regency. The activities carried out include providing counselling on stunting. Agricultural development activities are carried out by using household waste to transform it into compost using biocompost techniques.
