Abstract

In this study, there is no division between addiction in the mild and severe stages. Therefore, it is necessary to divide the stages of addiction because the healing is clearly different. Therefore, in this study, a modified dynamic analysis of the Social Media addiction model is carried out to obtain a valid model that can be implemented in real life. This study aims to find the stability of changes in the Addicted variable which is divided into two, namely Social Media addiction in the mild stage and Social Media addiction in the severe stage  There are six models that have been modified in this study, namely, individuals who do not have Social Media but are vulnerable to addiction , individuals who have Social Media but are not yet at the addiction stage , individuals infected with Social Media addiction in the mild stage , individuals infected with Social Media addiction in the severe stage , individuals who are recovering from Social Media addiction , individuals who are completely recovered from Social Media addiction . The steps of dynamic analysis include determining the equilibrium point, analyzing the stability of the equilibrium point, finding the basic reproduction number, numerical simulation of all variables. The results showed that the population of individuals infected with Social Media addiction in the mild stage  was at a value of 1.6112 with t = 4 years while the population of individuals infected with Social Media addiction in the severe stage  was at a value of 36.542 with t = 4 years. This study provides information that the dynamic analysis carried out on the modified mathematical model of Social Media addiction shows a stable condition.

Abstract

Indonesia is susceptible to natural disasters, with its geographical location being one of the contributing factors. To mitigate the harmful effects of natural catastrophes, a disaster emergency response must be undertaken, consisting of steps taken immediately following the event. These operations include rescuing and evacuating victims and property, addressing basic needs, providing protection, and restoring buildings and infrastructure. Accurate data is required for adequate recovery after a disaster. The Badan Penanggulangan Bencana Daerah (BPBD) oversaw disaster relief efforts, but faulty damage assessments slowed restoration. Surveyor subjectivity and differing criteria result in discrepancies between reported damage and reality, generating issues during the post-disaster reconstruction. The objective of this study is to develop a prediction system to measure the extent of damage caused by natural disasters to buildings. The five criteria that decide the level of building damage after a disaster are building conditions, building structure condition, physical condition of severely damaged buildings, building function, and other supporting conditions. The data used are from the BPBD of Malang city from 2019 to 2023. This system would allow surveyors to make speedy and objective evaluations. Five different models were tested using the Neural Network Backpropagation approach. Model A2 produces the highest accuracy of 93.81%. A2 uses a 40-38-36-34 hidden layer pattern, 1000 epochs, and a learning rate 0.1. These findings can lay the groundwork for advanced prediction models in post-disaster building damage evaluation research.

Abstract

Inspiring teacher, adalah dambaan setiap peserta didik. Guru inspiratif bukan guru yang hanya mengejar kurikulum, tetapi lebih dari itu, mengajak siswa-siswanya berpikir kreatif. Kehadirannya meniscayakan kemajuan dalam organisasi pembelajaran. Salah satu upaya yang kini sedang disosialisasikan dan dianggap tepat adalah melalui Total Quality Manajement (TQM) atau manajemen mutu terpadu. Dalam dunia pendidikan dikenal dengan TQE (Total Quality Education) Esensi dari TQM maupun TQE adalah suatu filosofi dan menunjuk pada perubahan budaya dalam suatu organisasi (pendidikan), serta dapat menyentuh hati dan pikiran orang menuju mutu yang diidamkan. Walhasil, implikasinya, akan lahir peserta didik-peserta didik yang memiliki kepercayaan diri terhadap sekecil apapun potensi yang mereka miliki, yang dari potensi itu mereka yakin bahwa masa depannya akan menjadi bermakna. Dari tangan inspiring teacher akan muncul siswa-siswi cerdas dengan keaneka-ragaman kecerdasan yang mereka miliki, yang membedakan mereka satu sama lainnya.

Abstract

Penelitian ini bertujuan untuk menganalisis implementasi metode RACE dalam pemasaran digital di rumah sakit serta mengidentifikasi tantangan pada setiap tahapannya. Dengan menggunakan pendekatan kualitatif deskriptif, data diperoleh melalui wawancara mendalam, observasi partisipatif, dan analisis dokumen. Hasil penelitian menunjukkan bahwa RSUD telah memanfaatkan berbagai platform digital, seperti Instagram, Facebook, dan YouTube, namun optimalisasi mesin pencari (SEO dan SEM) masih terkendala keterbatasan anggaran sehingga membatasi jangkauan audiens. Pada tahap Act, keterlibatan audiens dinilai masih rendah karena kurangnya konten interaktif yang relevan. Tahap Convert memperlihatkan adanya peningkatan kunjungan pasien, namun proses konversi dari interaksi digital ke kunjungan fisik masih menghadapi tantangan, terutama dalam hal ketidakcocokan jadwal pasien dengan dokter serta keterbatasan fasilitas. Pada tahap Engage, RSUD berupaya membangun hubungan jangka panjang melalui komunikasi berkelanjutan, tetapi sistem tindak lanjut dan program loyalitas pasien masih memerlukan pengembangan lebih lanjut. Penelitian ini terbatas pada analisis di satu rumah sakit dengan pendekatan kualitatif, sehingga hasilnya mungkin tidak sepenuhnya mewakili kondisi yang lebih luas. Meskipun demikian, studi ini memberikan kontribusi dalam memahami penerapan metode RACE dalam pemasaran digital di rumah sakit serta menawarkan rekomendasi strategis untuk meningkatkan efektivitas pemasaran, memperluas jangkauan audiens, memperbaiki proses konversi, serta membangun loyalitas pasien secara lebih berkelanjutan.

Abstract

The main problem of this research is based on the phenomenon of students' inability to interact with people outside of campus, so that they are often viewed cynically by societies. The location of the research is in Serule Kayu and Kute Tanyung villages, Kecamatan Bukit Kabupaten Bener Meriah,  which are the two villages where KPM UIN Ar-Raniry students be placed in 2024. The data collection process was carried out through indepth interviews, Small Group Discussions with students, observation and documentation studies . The research results show that interaction is a common action that everyone always carries out in their lives, both individually and in groups. The students who are taking the subject of Kuliah Pengabdian Kepada Masyarakat (KPM), their ability to interact with the community is very important in order to successfully carry out their work program well.  The ability to interact will influence the success of KPM. The success of KPM students in Bukit District is influenced by 3 forms of interaction namely symbolic interaction, investigative interaction and pedagogical interaction. These three forms of interaction have been able to build effective collaboration with the community so that they can implement various programs that have been previously designed.

Abstract

This research investigates the application of optimal control in the Susceptible, Exposed, Addicted, Recovery, Quit (SEA_1 A_2 RQ) model to address social media addiction. The primary objective is to develop an effective control strategy to reduce the prevalence of social media addiction. The methodology employs Pontryagin's maximum principle to formulate the optimal control problem, incorporating two time-dependent control variables: control (u_1) and treatment (u_2). The optimal control model is numerically simulated using the 4th-order Runge-Kutta method. Comparative analysis of the simulation results, with and without control, demonstrates significant differences in all population groups after four years. The findings reveal that implementing control (u_1) and treatment (u_2) markedly decreases the number of individuals addicted to social media, highlighting the efficacy of the proposed strategy in mitigating social media addiction.Keywords: optimal control; social media addiction model; Pontryagin maximum principle. AbstrakPenelitian ini mengkaji penerapan kontrol optimal pada model Susceptible, Exposed, Addicted, Recovery, model Quit (SEA_1 A_2 RQ)  untuk menangani kecanduan sosial media. Tujuan utama penelitian ini adalah untuk mengembangkan strategi kontrol yang efektif untuk mengurangi jumlah individu yang mengalami kecanduan media sosial. Metodologi penelitian ini menggunakan prinsip maksimum Pontryagin untuk merumuskan masalah kontrol optimal, yang menggabungkan dua variabel kontrol bergantung pada waktu: pengendalian (u_1) dan pengobatan (u_2). Model kontrol optimal disimulasikan secara numerik menggunakan metode Runge-Kutta orde 4. Analisis komparatif dari hasil simulasi, dengan dan tanpa kontrol, menunjukkan perbedaan yang signifikan pada semua kelompok populasi setelah empat tahun. Temuan tersebut mengungkapkan bahwa penerapan pengendalian (u_1) dan pengobatan (u_2) secara signifikan mengurangi populasi pengguna kecanduan sosial media, yang menyoroti kemanjuran strategi yang diusulkan untuk mengurangi kecanduan sosial media.Kata Kunci: kontrol optimal; model kecanduan media sosial; prinsip maksimum Pontryagin. 2020MSC: 49N90, 91D10, 92B05.

Abstract

This study aims to examine the influence of social media and e-commerce on the marketing performance and sales levels of Bangka Belitung white pepper products, with marketing performance acting as a mediating variable. The research employs a quantitative approach and uses Partial Least Squares–Structural Equation Modeling (PLS-SEM) to analyze data collected from local micro, small, and medium enterprises (MSMEs). The results indicate that social media has a significant positive effect on both marketing performance and sales levels, both directly and indirectly, highlighting its effectiveness as a marketing tool. This is attributed to its ease of access, wide reach, cost efficiency, and interactive capabilities, which enable MSMEs to engage directly with consumers and expand their market presence. In contrast, e-commerce does not demonstrate a significant impact on either marketing performance or sales levels. This lack of effect is likely due to limited adoption among MSMEs, who perceive e-commerce platforms as less practical because of registration complexities, associated fees, and concerns regarding consumer trust and payment security. The study suggests that while social media can be leveraged effectively for marketing Bangka Belitung white pepper, greater awareness, training, and support are needed to increase MSMEs’ engagement with e-commerce to enhance their overall sales and competitive performance in the digital market.
