Abstract

Operasi pada hipergraf adalah suatu cara untuk mengkonstruksi suatu hipergraf dengan struktur yang lebih besar. Salah satu operasi pada hipergraf yang biasa dipelajari adalah operasi kali Kartesius. Suatu hipergraf dikatakan integral jika semua nilai karakteristik dari matriks ketetanggaannya adalah bilangan bulat. Dalam makalah ini, dipelajari dua kelas hipergraf yaitu, bidang Fano dan latin square orde 3. Dapat ditunjukkan bahwa kedua kelas hipergraf tersebut adalah integral. Selanjutnya, ditentukan hipergraf hasil operasi kali Kartesius dari kedua hipergraf tersebut. Dapat dibuktikan bahwa operasi kali Kartesius pada hipergraf mempertahankan sifat keintegralan.

Abstract

Penuaan yang sukses (successful aging) merupakan tujuan penting dalam meningkatkan kualitas hidup lansia. Namun, lansia di panti kerap menghadapi keterbatasan dalam interaksi sosial, dukungan emosional, serta aktivitas fisik yang beragam, yang dapat menghambat tercapainya kondisi ideal tersebut. Penelitian ini bertujuan untuk mengeksplorasi pengalaman lansia dalam menjalani masa tua di Panti Werdha Elim dengan menggali makna lansia terkait kesejahteraan, dukungan sosial, dan tantangan yang mereka hadapi dalam kehidupan sehari-hari. Penelitian ini menggunakan pendekatan kualitatif dengan pengumpulan data dilakukan melalui tiga teknik, yaitu observasi, wawancara dan dokumentasi. Hasil penelitian menunjukkan bahwa lansia yang berada di panti jompo masi bisa melakukan aktivitas harian secara mandiri, secara kesejahteraan psikologis para lansia mampu menerima diri meskipun merasa kesepian, bagi para lansia panti dapat menjadi tempat interaksi sosial yang suportif, dan aktivitas spiritual memberikan ketenangan batin. Temuan ini menegaskan pentingnya dukungan komprehensif untuk mendukung kualitas hidup lansia dalam kerangka successful aging.

Abstract

This research aims to determine the meaning behind the cover of the 11-17 November 2019 issue of Tempo magazine with the main title "Anies' Budget Disgrace", which includes a caricature of one of the national figures, so as not to cause wild opinions and noise in the community. This research uses a qualitative approach method that produces descriptive data, with primary data obtained from the documentation of Tempo magazine and secondary data obtained from relevant literature and journals. The collected data is then analysed using Charles Sanders Pierce's semiotics with its trichotomous concept. The results of this study show that Tempo magazine has fulfilled its function of social control and is directly involved in monitoring issues of public interest. The caricature of Anies, depicted by Tempo as trapped in DKI Jakarta's budgeting system, is depicted as falling into a can of glue. The can is a packet of Aica-Aibon glue, which is believed to be one of the budget items with a fantastic purchase value.Keywords: controversy, cover magazine; semiotics; tempo

Abstract

Toxic relationships in dating are increasingly prevalent among adolescents and young adults and may lead to significant psychological consequences for the victims. This study aims to explore how victims of toxic relationships regulate their emotions in the process of developing resilience after experiencing dating violence. This research employed a qualitative approach with a case study design. Data were collected through semi-structured interviews with three female participants aged 17–22 years who had experienced unhealthy dating relationships. The data were analyzed using thematic analysis to identify patterns of emotional experiences and emotion regulation strategies used by the participants. The findings reveal that the participants experienced various forms of violence, including physical abuse, sexual coercion, economic exploitation, and possessive behaviors that restricted their personal freedom. These experiences triggered emotional responses such as sadness, anger, fear, and feelings of helplessness. Despite these challenges, the participants gradually developed coping strategies through emotion regulation, such as seeking social support, engaging in positive activities, and reconstructing healthier perspectives on relationships. The study highlights that adaptive emotion regulation and social support play crucial roles in helping victims of toxic relationships build resilience and move forward with their lives in a more constructive way. Keywords: Dating violence; Emotion regulation; Psychological recovery; Resilience; Toxic relationship.

Abstract

In this study, we developed a deterministic mathematical model to analyze social media addiction, incorporating an optimal control strategy. The basic model captures the dynamics through which individuals become exposed to and eventually addicted to social media platforms. To enhance the model, we introduced two time-dependent control variables: one representing awareness campaigns through advertising and education, and the other representing treatment interventions for individuals suffering from addiction. An optimal control framework was then formulated based on these interventions. By applying Pontryagin’s Minimum Principle, we derived the necessary conditions for optimality and constructed the corresponding optimality system. Numerical simulations of the optimal control problem were conducted using the forward-backward sweep method to assess the effectiveness of the proposed strategies. The results demonstrate that the integrated control strategy—combining public awareness efforts with treatment interventions— substantially reduces the number of individuals exposed to and addicted to social media. Compared to scenarios without intervention, the number of affected individuals was significantly lower. These findings underscore the importance of implementing combined strategies rather than isolated measures. Therefore, this integrated approach is strongly recommended for policymakers and stakeholders as a practical and effective means to mitigate the adverse effects of social media addiction on public health and societal well-being.. Keywords: Social Media Addiction, Mathematical Model, Pontryagin Minimum Principle, Optimal Control.

Abstract

This study presents a comparative evaluation of hybrid ARIMA-family forecasting models combined with Artificial Neural Networks (ANNs) for seasonal fish-catch prediction in Bengkulu waters, Indonesia, while assessing the role of sea surface temperature (SST) as an environmental predictor. Monthly SST data from NASA’s Giovanni portal and pelagic fish-catch records collected between January 2017 and June 2025 were used to develop ARIMA, ARIMAX, SARIMA, and SARIMAX models, whose residuals were subsequently modeled using Feedforward Neural Networks (FFNN) and Long Short-Term Memory (LSTM) networks to capture nonlinear temporal dependencies. Among the evaluated models, the hybrid ARIMA–LSTM achieved the highest forecasting accuracy on the available dataset, with an RMSE of 76.779 and a MAPE of 19.223%, whereas hybrid models that explicitly incorporate SST as a linear exogenous predictor showed lower predictive performance. These findings suggest that although SST remains an ecologically important environmental driver of pelagic fisheries, its predictive contribution may be better captured by nonlinear, lag-dependent relationships embedded in historical fish-catch observations rather than by contemporaneous linear exogenous modeling. Overall, this study provides empirical evidence for selecting appropriate hybrid forecasting models under practical fisheries data conditions and highlights their potential application as analytical components within fisheries Decision Support Systems (DSS) for adaptive fisheries management.
