Abstract

For a graph G that have vertex set V and edge set E. A labelling f:VUE->{1,2,3,...,k} is called a vertex irregularity total k-labeling of G if for any two different vertices x and y in V have wt(x)\neq wt(y) where wt(x)=f(x)+∑_{yV(G)} f(xy). The smallest positive integer k such that G has a vertex irregular total k-labeling is called the total vertex irregularity strength of G  , denoted by tvs(G).In this paper, we determined the total vertex irregularity strength of Unidentified Flying Object Graph, tvs(U_(m,n}). The result in this paper as follows: tvs(U_{m,n})=(3n+1)/2 for 3<=m<=3((n+1)/2), n>=3, andtvs(U_{m,n})=(3n+m)/3 for m>3((n+1)/2), n>=3.

Abstract

Cryptography is a method for securing data or information from data leaks. In cryptography, there are two important processes, namely, the encryption and decryption processes. Encryption is the process of changing plaintext into ciphertext using certain keys and algorithms, while decryption is the process of changing ciphertext into plaintext using keys and algorithms that match the encryption. There is a cryptosystem that is well known, namely Cipher Hill. Cipher Hill uses a square matrix for the encryption and decryption process. In this research, an mxn-sized matrix will be used over the Direct Sum ring Z_p⨁Z_q⨁Z_r to expand the Cipher Hill algorithm. The author also uses the pseudoinverse concept to find the inverse of an mxn matrix. By using an mxn matrix, the encryption results allow the length of the plaintext to be different from the length of the ciphertext.Keywords: Cipher Hill, Cryptography, Decryption, Encryption, Direct Sum, Pseudoinvers

Abstract

Learning Management System (LMS) is an innovation in the learning process that allows online learning to be more effective and efficient. Like many other higher education institutions, Universitas Negeri Malang provides opportunities for innovation and easy access to knowledge by utilizing an LMS called the Sistem Pengelolaan Pembelajaran (SIPEJAR). SIPEJAR is an open-source system that can be modified according to the user's needs and desires. The aim of this research is to develop SIPEJAR content packages by using the ADDIE model for statistics for education courses with drone-based learning. SIPEJAR development products include lesson plans, textbooks, and SIPEJAR content packages for 16 meetings. Drone-based development is focused on developing explanatory videos, presentation slides, and student interaction with learning materials. The finding results indicated that the drone-based development of SIPEJAR content packages is valid with an average score of 3.77 out of 4, practical with an average score of 4.19 out of 5, and quite effective with classical completeness percentage obtained was 60% with an average score of 74.63. This means that drone-based SIPEJAR content packages have been well developed, even though they can be improved further. Our research findings indicated that the E-LKPD is valid with a percentage of 91.00%, practical with a percentage of 89.05%, and effective with a classical learning completeness percentage of 82.76%

Abstract

This study aims to identify and analyze the variables that affect the open unemployment rate in Banten Province, Indonesia. The analyzed variables include population density, average years of schooling, labor force participation rate, minimum wage, Provincial GRDP, total labor force, and the number of poor people. The method used in this study is multiple linear regression analysis with secondary data from the Central Bureau of Statistics (BPS) for the period 2017–2022. The analysis revealed multicollinearity in the average years of schooling variable, with a Variance Inflation Factor (VIF) >10. To address this issue, Lasso regression and Elastic Net regression were applied. The results of this study show that Lasso regression produces a model with a Mean Squared Error (MSE) of 1.3234857, while Elastic Net regression yields a model with a lower MSE of 0.180683, indicating better predictive performance. The best model for predicting the open unemployment rate in Banten Province is the Elastic Net regression. The variables that significantly affect the open unemployment rate are average years of schooling, labor force participation rate, minimum wage, Provincial GRDP, total labor force, and the number of poor people. The conclusion of this study is that Elastic Net regression is more effective in predicting the open unemployment rate than other methods. The implication of these findings is that the generated model can serve as a basis for formulating more effective labor policies to reduce the unemployment rate in Banten Province.

Abstract

Farmer groups in Sidorejo Village, Blitar, face significant challenges characterized by the low added value of pineapple harvests and minimal innovation in post-harvest processing, including waste utilization. This community service project aimed to enhance the skills of partner groups in processing pineapple fruit and peel into economically valuable probiotic beverages using fermentation methods packaged attractively. The activity primarily involved the PKK women's group of Sidorejo Village and was conducted in-person. The methodology included education, direct demonstration of product creation, named Pinaboocha (pineapple kombucha) and Pinatepa (pineapple tepache), and packaging mentoring. Post-training evaluation revealed a significant increase in competence while 85% of participants understood the benefits of Pinaboocha and Pinatepa, and 85% expressed interest in developing these beverages into a business. These findings demonstrate that innovating the processing of pineapple fruit and waste through fermentation not only increases product quality but also successfully creates new, sustainable business opportunities based on local potential.
