Abstract

Graph labeling is a map that maps graph elements such as vertices, edges, vertices, and edges to a set of numbers. A graph labeling is named e-cordial if there is a binary mapping f:E(G)→{0,1} which induces the vertex labeling defined by g(v)=Ʃ_{uvϵE(G)}f(uv)(mod 2), so that it satisfies the absolute value of the difference between the number of vertices labeled 1 and the number of vertices labeled 0 is less than equal to 1, and also for the number of edges labeled 0 and labeled 1. A graph that admits the e-cordial labeling is called an e-cordial graph. In this paper, we proved that some of the cupola graph Cu(3,b,n) is e-cordial.Keywords: E-Cordial Labeling; E-Cordial Graph; Cupola Graph Cu(a, b, n). AbstrakPelabelan graf merupakan pemetaan yang memetakan unsur-unsur graf seperti simpul, sisi, simpul dan sisi ke himpunan bilangan. Sebuah pelabelan dinamakan pelabelan e-cordial jika terdapat pemetaan biner f:E(G)→{0,1} yang menginduksi pelabelan simpul yang didefinisikan g(v)=Ʃ_{uvϵE(G)}f(uv)(mod 2) sehingga nilai mutlak dari selisih banyaknya simpul yang dilabeli 1 dan banyaknya simpul yang dilabeli 0 kurang dari sama dengan 1, dan nilai mutlak dari selisih banyaknya sisi yang dilabeli 1 dan banyaknya sisi yang dilabeli 0 kurang dari sama dengan 1. Sebuah graf yang dapat dilabeli secara e-cordial dinamakan graf e-cordial. Pada makalah ini dibuktikan bahwa beberapa graf kubah Cu(3,b,n) adalah e-cordial.Kata Kunci : Pelabelan E-Cordial; Graf E-Cordial; Graf Kubah Cu(a, b, n).

Abstract

Since a reliable internet signal has become an essential and significant need nowadays, the existence of modems as transmitters of internet signals is also crucial; modems transmit the internet signal (without cable), which is then captured by devices. This research aims to construct a mathematical model to determine the minimum number of modems and their placement so that the entire building FPMIPA-A of UPI has a good internet signal. In this research, we assume that the modem can pass through at most two walls, and the area studied is limited to the first floor of FPMIPA-A. The model is based on the illumination problems theorems, one of which states that every monotone 6-gon can be covered by a single 2-modem point placed at one of its two leftmost (or rightmost) vertices.  By the theorem, we view the layout of the rooms in the building as a combination of polygons. The results show that 12 modems are required to cover all areas on the first floor of FPMIPA-A to get a good signal.Keywords: illumination problem; modem; polygonal regions; optimal modem placement; building FPMIPA A. AbstrakSaat ini, kebutuhan akan sinyal internet yang andal menjadi kebutuhan penting dan utama. Modem sebagai pemancar sinyal internet mengirimkan sinyal internet (tanpa kabel) dan kemudian ditangkap oleh perangkat. Penelitian ini bertujuan untuk membangun model matematika yang menentukan jumlah minimum modem dan penempatannya agar seluruh gedung FPMIPA-A UPI mempunyai sinyal internet yang baik. Pada penelitian ini diasumsikan modem dapat menembus paling banyak dua dinding dan area yang diteliti dibatasi pada lantai 1 gedung FPMIPA-A UPI. Model matematika untuk masalah penempatan modem ini didasarkan pada teorema masalah iluminasi, yang salah satunya menyatakan bahwa setiap 6-gon monoton dapat ditutupi oleh satu titik 2-modem yang ditempatkan di salah satu dari dua simpul paling kiri (atau paling kanan).  Berdasarkan teorema tersebut, tata ruang pada lantai 1 gedung FPMIPA-A UPI dipandang sebagai kombinasi poligon. Hasil penelitian menunjukkan bahwa dibutuhkan 12 modem untuk mencakup seluruh area di lantai 1 FPMIPA-A guna mendapatkan sinyal yang baik. Kata Kunci: masalah iluminasi; modem, daerah poligon; penempatan modem secara optimal; gedung FPMIPA A. 2020MSC: 90C90.

Abstract

In this paper, we determine the chromatic number of the corona product of complete graph $K_n$ and star graph $K_{1,m}$. Determination of the chromatic numbers is done by observing patterns, constructing conjectures, and proving them formally. We found that the chromatic number of the corona product of complete graph $K_n$ and star graph $K_{1,m}$ is $\chi\left(K_n\odot K_{1,m}\right)=\left\{\begin{matrix}3,\ \ n=1,2\\n,\ n=3,4,\ldots,\ k\\\end{matrix}\right.$, and the chromatic number of the corona product of star graph $K_{1,m}$ and complete graph $K_n$ is $\chi\left(K_{1,m}\odot K_n\right)=n+1,\ n=1,2,\ldots,\ k$. Furthermore, using Matlab software, a program is created to visualize the coloring of the vertices based on the formula that has been obtained.

Abstract

In this study, a mathematical model for cancer chemotherapy drug scheduling was developed, which is the problem of scheduling drugs given to patients. The mathematical model developed has an objective function of reducing cancer cells while reducing toxicity in the patient's body, with constraints in the form of limits for the number of healthy cells, cancer cells, drug concentration, and patient toxicity. The influential and interrelated variables are arranged in a system of differential equations consisting of the number of healthy cells, number of cancer cells, drug dose, drug concentration, patient toxicity and drug effect, which describes the chemotherapy of non-specific cancer cell cycles. Optimal solution was obtain numerically using Runge-Kutta Method and Non-dominated Sorting Genetic Algorithm-II (NSGA-II). The results showed that this algorithm was able to produce a solution with an optimal dosing schedule every 8 days for 106 days with 14 drug doses. Doses ranged from 20.00 to 29.55 mg/m² with an average of 24.28 mg/m² and a standard deviation of 3.64 mg/m² so as to minimize the number of cancer cells and damage to healthy cells.

Abstract

Stock investment has become increasingly popular in Indonesia, and the construction of an optimal portfolio is essential for effective risk and return management. This study integrates the Capital Asset Pricing Model (CAPM) with the Simulated Annealing algorithm to optimize stock portfolios. The Simulated Annealing algorithm enables flexible and realistic portfolio management by addressing non-linear complexities and market constraints. In addition, this study develops a Graphical User Interface (GUI)-based application using Python to assist investors in calculating and determining optimal portfolio allocations. The application utilizes stock data and investment parameters as inputs and produces optimal allocation outputs based on CAPM and heuristic solutions generated by the Simulated Annealing algorithm. This research offers an efficient and adaptive solution for portfolio optimization in a fluctuating market environment.

Abstract

This study aimed to examine trends and patterns in mathematical literacy research in Indonesia, as an essential component of mathematics education. Using a systematic literature review, this study analyzed 18 Scopus-indexed articles published between 2021 and 2025. This study examined the distribution of publications across journal quartiles, years, geographic research sites, research methods, mathematical topics, and educational levels. The results showed an upward trend in publications in recent years, with most studies appearing in mid-tier journals. Among the reviewed studies, qualitative methods were the most frequently employed research approach. The investigated topics were mainly concentrated on shape and space, and most studies focused on the junior high school level, while other levels received less attention. In addition, research sites were unevenly distributed, with concentrations in certain provinces. These findings indicate that mathematical literacy research in Indonesia has developed steadily but remains concentrated in specific contexts, offering opportunities for broader coverage in future studies.

Abstract

Numeracy literacy is a fundamental skill required by students to apply mathematical concepts in everyday life; however Indonesian students still face obstacles, particularly with decimal numbers. This research aims to analyze learning obstacles in numeracy literacy on the topic of decimal numbers.  The method used is descriptive  qualitative with triangulation techniques in data collection. The research result identify three interrelated categories of obstacles, namely ontogenetic obstacles in the form of limited mental readiness and prerequisite understanding, epistemological obstacles in the form of errors in decimal operations, and didactic obstacles that include conventional learning and reliance  on a single textbook. Didactic obstacles play a central role in  exacerbating the other two obstacles. This study concludes that learning design based on the GASING method has the potential to be an effective pedagogical alternative in reducing those learning obstacles.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk menumbuhkan kecerdasan logis-matematis warga belajar di salah satu Pusat Kegiatan Belajar Masyarakat (PKBM) di Kabupaten Bandung Barat, Provinsi Jawa Barat. Kegiatan ini dilatarbelakangi oleh hasil observasi bahwa pembelajaran matematika paket B belum mengoptimalisasikan media dalam proses belajarnya termasuk alat peraga. Hal ini disebabkan karena media belum terfasilitasi dengan baik, padahal belajar matematika dengan alat peraga dapat menumbuhkan tantangan bagi pembelajar termasuk alat peraga menara hanoi. Pengabdian terdiri dari beberapa tahapan yaitu observasi, pelaksanaan, dan evaluasi. Dalam pelaksanaan kegiatan warga belajar dibagi menjadi tiga kelompok dan mencoba mencari langkah minimum perpindahan dan menganalisis strategi yang harus digunakan untuk mencapai tujuan. Berdasarkan hasil angket kecerdasan logis-matematis didapatkan bahwa menara hanoi dapat menumbuhkan kecerdasan logis-matematis lebih dari 70% warga belajar, sehingga dapat dikatakan bahwa alat peraga ini cocok digunakan untuk menumbuhkan kecerdasan logis matematis dalam proses pembelajaran khususnya pada materi pola bilangan. This community service activity aims to foster the logical-mathematical intelligence of learning residents at one of the Community Learning Activity Centers (PKBM) in West Bandung Regency, West Java Province. This activity was motivated by the observation that package B mathematics learning had not optimized the media in the learning process, including teaching aids. This is because the media has not been well facilitated, even though learning mathematics with visual aids can create challenges for students, including the Hanoi tower props. The service consists of several stages: observation, implementation, and evaluation. In carrying out the activity, students are divided into three groups and try to find the minimum steps of movement and analyze the strategies that must be used to achieve the goal. Based on the results of the logical-mathematical intelligence questionnaire, it was found that the hanoi tower can foster logical-mathematical intelligence of more than 70% of the learning population, so it can be said that this teaching aid is suitable for growing logical-mathematical intelligence in the learning process, especially in number pattern material.

Abstract

Diabetes melitus (DM) merupakan gangguan metabolisme yang ditandai dengan peningkatan kadar glukosa darah (hiperglikemia). Jumlah penderita DM terus meningkat secara global, dan Indonesia menempati peringkat keempat negara dengan jumlah kasus terbanyak di dunia. Penelitian ini membangun model matematika Susceptible--Exposed--Infected--Treated--Recovered (SEITR) untuk menggambarkan dinamika perkembangan jumlah penderita DM dengan melibatkan faktor risiko biologis seperti genetik dan non-genetik, serta pengaruh pola hidup dan perawatan. Hasil analisis menunjukkan bahwa terdapat dua titik ekuilibrium, yaitu ekuilibrium bebas penyakit dan endemik yang bersifat stabil jika transisi individu sehat menjadi pradiabetes akibat faktor genetik, non-genetik, pola hidup buruk, dan laju kelahiran tidak lebih besar dibanding gabungan laju kehilangan dari status karena kematian alami, perkembangan ke DM, atau pengendalian.  Solusi numerik bersesuaian dengan analisa kualitatif dan menggunakan metode Runge-Kutta Fehlberg. Hasil simulasi menunjukkan bahwa pengendalian perkembangan DM dapat dilakukan melalui dua hal, yaitu meningkatkan laju pola hidup sehat dan meningkatkan pencegahan sejak fase pradiabetes.
