Abstract

Analisis klaster merupakan salah satu teknik untuk mengelompokan objek-objek sesuai kemiripan ciri yang dimilikinya. Analisis klaster terbagi menjadi dua yaitu hierarki dan non-hierarki. Penelitian ini menerapkan analisis klaster non-hierarki yaitu metode CLARA untuk menentukan klaster Kabupaten/Kota di Provinsi Sulawesi Selatan berdasarkan indikator Indeks Pembangunan Manusia (IPM) tahun 2020 dan 2021. IPM memiliki empat indikator yaitu umur harapan hidup, harapan lama sekolah, rata-rata lama sekolah, dan pengeluaran perkapita disesuaikan. Metode penelitian ini menggunakan metode CLARA dan data dari Badan Pusat Statistik Provinsi Sulawesi Selatan. Ukuran Jarak Yang digunakan adalah jarak Euclidean, dan untuk menentukan jumlah klaster terbaik menggunakan nilai koefisien Silhouette. Hasil klaster dengan nilai koefisien Silhouette dari metode CLARA diperoleh 2 klaster, yaitu klaster 1 dengan kategori indeks pembangunan manusia sedang ditempati oleh Kab. Kep. Selayar, Kab. Bulukumba, Kab. Bantaeng, Kab. Jeneponto, Kab. Takalar, Kab. Gowa, Kab. Sinjai, Kab. Maros, Kab. Pangkajene Kepulauan, Kab. Barru, Kab. Bone, Kab. Soppeng, Kab. Pinrang, Kab. Enrekang, Kab. Luwu, Kab. Tana Toraja, Kab. Luwu Utara, dan Kab. Toraja Utara. Sedangkan klaster 2 dengan kategori Indeks Pembangunan Manusia tinggi ditempati oleh Kab. Wajo, Kab. Sidenreng Rappang, Kab. Luwu Timur, Kota Makassar, Kota Pare-pare, dan Kota Palopo.

Abstract

This study aims to group districts / cities in South Sulawesi Province in 2021 that havesimilarities in community welfare variables using biplot analysis. Biplot analysis is an effort to makeimages in many-dimensional space into images in two-dimensional space, some important informationthat can be obtained are: proximity between observed objects, variable diversity, correlation betweenvariables and variable values of an object. This research uses the SVD (Singular Value Decomposition)method, with a research object of 24 districts / cities in South Sulawesi Province and consists of 13indicator variables. Based on the results of the study, the districts/cities that have similar indicators ofcommunity welfare are divided into 4 groups, group 1 is Makassar City, Pinrang and Luwu Regencies,group 2 is Pangkajene and Islands, Wajo, Takalar, Bulukumba, Soppeng, Bone, Jeneponto, Gowa,Maros, Sirenreng Rappang and Barru, group 3 namely Sinjai, North Luwu, Selayar Islands and Bantaengand group 4 namely Parepare City, Palopo City, Tana Toraja, North Toraja, East Luwu and Enrekang.With the greatest diversity of community welfare indicators are expected years of schooling (X4) andaverage years of schooling (X5). The variables that influence each other and are positively correlated.Namely, expectation of years of schooling (X4) and using a cellular phone (HP) (X12).

Abstract

Cluster analysis serves to group objects with high similarity of characteristics in one cluster while objects with dissimilarity of characteristics are in different clusters. Cluster analysis is divided into two, namely hierarchical and non-hierarchical. This study applies a non-hierarchical cluster analysis, namely the k-medoid method to group districts/cities and their four sectors, namely transportation, industrial/agroindustrial, residential, office/commercial in South Sulawesi Province based on indicators that make up the 2019 Air Quality Index (AQI) value and 2020. AQI are categorized based on six Environmental Quality Index (EQI) statuses. To get the best clusters from the k-medoid process, each cluster needs to be evaluated using the silhouette coefficient value. The results of this study indicate that k = 2 clusters from the k-medoid method are the best cluster initiations with the best silhouette coefficient value of 0.56. The results of the analysis of the cluster results show that with the use of 2 clusters, for 2019 passive sampler data, cluster 1 is included in the very good EQI category with a AQI value of 84.14 and cluster 2 is in the less EQI category with an AQI value of 60.04. For the 2020 passive sampler data, cluster 1 is included in the good EQI category with a AQI value of 80.68 and cluster 2 is in the less EQI category with a AQI value of 61.53.

Abstract

This research is an applied research that aims to find out the clusters that exist in students of the Mathematics Department of FMIPA UNM using K-Means Clustering. This research method is a literature study. The results of the study obtained 4 clusters where the duration of independent learning and GPA from highest to lowest were Cluster 1, Cluster 2, Cluster 4, and Cluster 3. Cluster 1 was dominated by SBMPTN students, Semester 3, average age 19.20 years, duration of self-study 2.49 hours, 23.97 credits, 3.69 IPS, and 3.67 GPA. Cluster 2 is dominated by SBMPTN students, Semester 1, average age 18.08 years, duration of independent study 2.07 hours, 22 credits, 3.64 IPS and GPA 3.63. Cluster 4 is dominated by MANDIRI students, Semester 5, average age 19.78 years, duration of independent study 1.89 hours, 21.62 credits, 3.48 IPS, and 3.36 GPA. Cluster 3 is dominated by SBMPTN and SNMPTN students together, Semester 3, average age 18.52 years, duration of independent study 1.29 hours, 21.87 credits, 3.13 IPS, and GPA 3.19. The most influential variables in the formation of clusters are Semester, Number of Credits, GPA, Age, Social Studies, Average Duration of Independent Study, and Entry Path

Abstract

This study focuses on the mathematical SER model capturing the rate of Ammotere Abbaji Case Behavior among individuals associated with Silariang. Primary data is gathered through questionnaires administered directly to the community in South Sulawesi Province, shedding light on the pace of Ammotere Abbaji Case Behavior among those involved with Silariang. The research journey starts with the construction of the SER model, followed by an analysis and simulation of the Ammotere Abbaji Case Behavior among Silariang participants. This encompasses identifying equilibrium points, evaluating model stability, computing the basic reproduction number (R0), conducting model simulations using Maple software, and interpreting the simulation results. Within this article, the mathematical SER model emerges through the analytical lens and simulation of Ammotere Abbaji Case Behavior among Silariang participants. Two equilibrium points are discovered: the free equilibrium point of Ammotere Abbaji Case Behavior among Silariang participants, and the equilibrium point specific to this behavior. The calculated basic reproduction number R0=0.045 indicates a decrease in the population engaged in Ammotere Abbaji Case Behavior among Silariang participants.

Abstract

. Game theory is a branch of applied mathematics within operations research that focuses on studying and understanding competitive situations involving multiple parties. The rapid growth of e-wallet usage has significantly intensified competition in the digital sector. This study aims to analyze the optimal strategies in the e-wallet competition between GoPay, DANA, and OVO in Makassar City using game theory. The data utilized in this research were obtained through a questionnaire survey involving 100 student respondents. Six strategic attributes are examined: product, price, promotion, place, practicality, and security. The results indicate that in the competition between GoPay and OVO, GoPay's optimal strategy is to focus on promotion to maximize profits, while OVO's optimal strategy is prioritizing security to minimize losses. In the competition between DANA and OVO, DANA's optimal strategies include product, price, and place to achieve maximum profits, while OVO focuses on product, promotion, and place to minimize losses. Meanwhile, in the competition between DANA and GoPay, DANA's optimal strategies are price, practicality, and security to maximize profitability, while GoPay prioritizes price, place, and security to minimize losses. These findings demonstrate the varying strategic approaches each e-wallet employs to adapt to the competitive market dynamics and optimize outcomes based on their respective priorities and strengths
