Abstract

This paper aims to prove that some certain graphs, such as triangular book graphs, ladder graphs, snail graphs, and Cartesian product graphs between cycles and paths, belong to the category of mean graphs. We chose these graph classes because it is still an open problem. To prove the above, we use two main approaches, such as the axiomatic descriptive method and the pattern detection method. The axiomatic descriptive method is used to describe the basic properties of graphs and organise them into formal arguments, while the pattern detection method is used to observe and generalise the structural properties of graphs in a more exploratory manner. Based in the results of the analysis and proof, we conclude that the four classes of graphs studied, to be triangular book graphs, ladder graphs, snail graphs, and Cartesian product graphs of cycles and paths, are proven to satisfy the characteristics of mean graphs.

Abstract

The Academic Information System (SIAKAD) serves a pivotal function in enhancing both operational efficiency and the quality of academic services within higher education institutions, particularly amidst the accelerating shift toward digitalization in the education sector. Despite its strategic importance, the effectiveness of SIAKAD implementation is contingent upon the level of user satisfaction—most notably that of students—which remains insufficiently explored through analytical models capable of capturing intricate causal relationships. This study seeks to empirically examine the determinants of student satisfaction in utilizing SIAKAD by investigating the influence of system quality, information quality, and ease of use, with perceived usefulness positioned as a mediating construct. The research adopts the Partial Least Squares Structural Equation Modeling (PLS-SEM) approach, which is methodologically appropriate for complex models involving latent variables and non-normally distributed data. The analysis is based on survey data collected from 128 active undergraduate students at Universitas Patompo. The empirical findings indicate that information quality exerts a significant direct influence on student satisfaction (β = 0.547; p < 0.001) and an additional indirect effect mediated by perceived usefulness (β = 0.268; p < 0.001). Conversely, system quality and ease of use demonstrate no statistically significant effects. The coefficient of determination values (R² = 0.706 for satisfaction; R² = 0.615 for perceived usefulness) reflect a strong predictive capability of the model. These results affirm that information quality is the most salient predictor of user satisfaction, underscoring the imperative to prioritize content enhancement as a strategic direction in the advancement of academic information systems within the higher education landscape.

Abstract

This study aims to explore the pattern of diabetes mellitus risk factors among patients at Torabelo Regional Hospital in Sigi using Multiple Correspondence Analysis (MCA). A total of 465 patients were analyzed based on eight categorical variables, including age, gender, blood glucose levels, and lipid profiles. MCA was applied to identify inter-category relationships and visualize them in a low-dimensional space. The results show that most diabetes patients were female, aged 46 years and above, and had high fasting glucose, low HDL, and high LDL levels. The analysis identified two main patterns: a group with a low-risk metabolic profile who were not diagnosed with diabetes, and a group with a combination of high-risk metabolic categories who were more likely to already have diabetes. A distinct subgroup with extremely high triglyceride levels was also identified, indicating a rare but significant metabolic pattern. The first two dimensions of the MCA explained more than 40% of the data variation, providing sufficient support for meaningful visual interpretation. These findings demonstrate that MCA is effective in simplifying complex categorical data and supports risk-based segmentation strategies for early intervention planning in primary healthcare services, particularly in regions with high diabetes prevalence.

Abstract

Dimensi partisi dominasi merupakan konsep yang menggabungkan dua ide penting dalam teori graf: partisi pembeda dan himpunan dominasi. Misalkan G  adalah suatu graf terhubung dan Γ={L-1, L_2, . . . , L_k} adalah partisi terurut dari himpunan titik graf G. Suatu partisi Γ disebut partisi pembeda jika untuk setiap sepasang titik u  dan v , jarak antara u dan L_j  tidak sama dengan jarak v dan L_j untuk suatu L_j ϵ Γ. Suatu partisi pembeda Γ dikatakan partisi pembeda dominasi jika untuk setiap titik u di  G jarak antara titik u dan suatu kelas partisi L_j adalah satu. Selanjutnya, dimensi partisi graf G adalah kardinalitas minimum dari suatu partisi pembeda dari G . Adapun kardinalitas minimum dari suatu partisi pembeda dominasi dari G disebut dimensi partisi dominasi.  Sebagai pengembangan penelitian dalam kajian dimensi partisi dominasi, dalam makalah ini dikaji dimensi partisi dominasi graf dalam kelas pohon. Hasil dari penelitian ini menunjukkan dimensi partisi dominasi untuk graf bintang ganda, graf ulat, graf kembang api, dan graf pohon pisang.

Abstract

Children are the future generation of the nation and play a vital role in national development. However, those from low-income families are often forced into child labor, which can hinder their educational attainment. Balancing work and school responsibilities frequently leads to school dropouts among child laborers. Sulawesi Island is one of the regions in Indonesia with a notably high prevalence of child labor. This study found that 16.39% of child laborers on Sulawesi Island dropped out of school. Using logistic regression analysis on data from the March 2022 National Socio-Economic Survey (Susenas), the study identified that a child's gender, age, poverty status, and the education level of the head of the household significantly influence the incidence of school dropout among child laborers.

Abstract

Village financial management is supported by several principles, namely transparency, accountability, participation, responsiveness, and competence. This study aims to determine the effect of good governance principles (transparency, accountability, participation, responsiveness, and competence) as independent variables on village financial management as the dependent variable in Takisung District, Tanah Laut Regency. The population in this study consists of village officials working in village and sub-district offices within the Takisung District area, with a sample of five village and sub-district offices and a total of 40 respondents. This study employs a quantitative approach with data collection techniques using questionnaires. Data analysis was carried out using descriptive statistics, data quality tests, classical assumption tests, multiple regression analysis, and hypothesis testing. The results show that both partially and simultaneously, transparency, accountability, participation, responsiveness, and competence have a significant effect on village financial management. The R-Square value of 0.979 or 97.9% indicates that these five principles of good governance dominantly determine the effectiveness of village financial management, while the remaining 2.1% is influenced by other factors outside this study. These findings imply that the consistent implementation of good governance principles can enhance accountability and efficiency in village financial management.

Abstract

Pemerintah Indonesia telah mengimplementasikan berbagai bentuk bantuan bersyarat kepada rumah tangga sasaran untuk mengurangi persentase penduduk miskin di Indonesia. Terdapat dua jenis bantuan yang telah dijalankan, yaitu bantuan tunai seperti KKS, PKH, dan PIP dan bantuan non tunai seperti BPNT. Penelitian ini bertujuan untuk melihat efek dari empat bantuan tersebut dalam upaya pengentasan kemiskinan. Unit analisis pada studi kasus ini adalah rumah tangga sampel SUSENAS Maret 2020 yang dilaksanakan di Provinsi Sulawesi Tenggara. Untuk menganalisis efek bantuan tersebut, penelitian ini menggunakan satu variabel terikat, yaitu status kemiskinan rumah tangga sampel yang terbagi dalam tiga kategori, dan empat variabel utama yaitu status penerima bantuan, serta sembilan variabel karakteristik rumah tangga sebagai variabel tambahan. Dengan menggunakan model multinomial logit, penelitian ini menemukan bahwa hanya bantuan KKS yang menurunkan peluang rumah tangga untuk dapat keluar dari garis kemiskinan pada rumah tangga yang terkategori miskin, sementara tiga bantuan lainnya (PKH, PIP, dan BPNT) tidak meningkatkan peluang untuk keluar dari garis kemiskinan.

Abstract

This study discusses forecasting the amount of rice procurement in South Sulawesi. The need increases every year because it is one of the staple foods of the Indonesian population that is consumed everyday. Related to this, to ensure the availability of stock of rice suppiles throughout the South Sulawesi region, this is done by estimating the number of procurements in terms of rice prices and rice production. The purpose of this study is to determine the forecasting model, the variables that have a relationship between variables and the results of forecasting the amount of rice procurement. The results obtained in this study indicate that the smallest AIC value is found in the length of lag 2 so that the model used is the VAR model (3). In addition, all the variables used have a significant effect. Then from the forecasting results obtained, the rice price variabes (Y1) and the amount of rice production (Y2) have MAPE values of 20,4 % dan 14,0 %, which means the forecasting results are good. The results of the forecast number of procurement based on the price in term of the price of rice and the amount of production in the text five years has increased every year.
