Abstract

The SIR model is a model used to group populations into 3 parts, namely susceptible or a subpopulation of individuals who are susceptible to disease, infected or a subpopulation of individuals who are infected and can transmit the disease and recovered or a subpopulation of individuals who have recovered from the disease. Measles is usually treated without a vaccine, so the disease is often found in the community. Giving the right and balanced vaccine will get results that are balanced with what is given. In this research, we develop a SIR model with additional controls. Where the control in this model is vaccination given to subpopulations S and I, so that the recovered subpopulation experiences an increase, because the number of subpopulation I decreases. The method used in this research consists of several steps, namely forming a SIR model which is formed in optimal control and determining the objective function. Next, solve the optimal control problem, which consists of several stages, namely forming the Hamiltonian function and finding states and co-states. Based on the research results, it is concluded that optimal control of the SIR model is obtained by state and co-state equations. Where this model is the result of reducing the Hamiltonian to obtain optimal control in the SIR model.

Abstract

The “back to nature” trend has begun to increase along with public awareness of the health hazards caused by chemicals in food and medicines. The use of plants as medicine has been carried out by tribes in Papua for hundreds of years and continues to this day. This use needs to be accompanied by knowledge about the proper use of traditional medicine so that there are no adverse side effects that can endanger life. The purpose of writing this manuscript is to share information about the knowledge of the Yewena Village community, Depapre District, Jayapura Regency, about TOGA and its use. Community service activities were carried out through counseling and workshop methods. The number of participants in the activity was 29 people. The results of the counseling activity on the use of natural medicine and TOGA showed that the participants experienced an increase in knowledge after participating in the counseling, based on the percentage of correct answers to the pre-test and post-test questions, which increased from 37.24% to 98.69%. The workshop was carried out in the form of creating a TOGA demonstration area around the Yewena Village Hall. The Yewena Village community, as counseling participants, experienced an increase in knowledge about the use of natural medicine and TOGA after the counseling activity. It is hoped that writing about TOGA and its use will become more widespread and numerous so that more people will have the awareness and willingness to use natural medicines properly and correctly. Tren kembali ke alam (back to nature) mulai meningkat bersamaan dengan kesadaran masyarakat terhadap bahaya kesehatan yang diakibatkan oleh bahan kimia dalam makanan maupun obat-obatan. Pemanfaatan tanaman sebagai obat telah dilakukan oleh suku-suku di Papua sejak ratusan tahun lalu hingga kini. Pemanfaatan tersebut perlu dibarengi dengan pengetahuan mengenai penggunaan obat tradisional secara baik dan benar agar tidak terjadi efek samping yang merugikan yang dapat membahayakan jiwa. Penulisan naskah ini bertujuan untuk memberikan informasi mengenai bagaimana pengetahuan masyarakat Kampung Yewena, Distrik Depapre, Kabupaten Jayapura tentang TOGA dan pemanfaatannya. Kegiatan pengabdian dilakukan melalui metode penyuluhan dan workshop. Peserta kegiatan berjumlah 29 orang. Hasil kegiatan penyuluhan pemanfaatan obat bahan alam dan TOGA adalah peserta kegiatan mengalami peningkatan pengetahuan setelah mengikuti penyuluhan berdasarkan persentase jawaban benar pada pertanyaan pre-test dan post-test yaitu dari 37.24% menjadi 98.69%. Workshop yang dilakukan berupa pembuatan lahan percontohan TOGA di sekitar balai Kampung Yewena. Masyarakat Kampung Yewena sebagai peserta penyuluhan mengalami peningkatan pengetahuan mengenai pemanfaatan obat bahan alam dan TOGA setelah kegiatan penyuluhan. Diharapkan penulisan mengenai TOGA dan pemanfaatannya lebih luas dan banyak lagi sehingga semakin banyak masyarakat yang memiliki kesadaran dan kemauan untuk menggunakan obat bahan alam secara baik dan benar.

Abstract

This study develops a Susceptible–Exposed–Infectious–Recovered (SEIR) mathematical model with two time-dependent optimal control strategies educational campaigns and medical treatment to analyze Ebola transmission. The nonlinear system is examined using Pontryagin’s Minimum Principle, and the optimality system is solved numerically through the Forward–Backward Sweep Method in MATLAB. Simulation results show that combined controls substantially reduce the peak number of infected individuals, decrease cumulative infection cases, and shorten the epidemic duration compared to the uncontrolled scenario. Early implementation of both interventions further improves epidemic suppression and reduces the overall cost functional value. These results demonstrate the effectiveness of integrated control strategies and highlight mathematical modeling as a decision-support tool in public health planning.

Abstract

Penguatan literasi dan numerasi anak sangat penting untuk meningkatkan kualitas pendidikan dasar di Papua. Kegiatan pengabdian masyarakat ini dilaksanakan di Rumah Baca Ayapo, Sentani Timur, Papua, pada 4 dan 12 Juli 2025 dengan melibatkan 26 anak. Metode pelaksanaan dilakukan secara terstruktur melalui tiga tahapan utama: (1) Tahap persiapan, meliputi koordinasi mitra, penyusunan aturan permainan, dan instrumen evaluasi; (2) Tahap pelaksanaan, menggunakan pendekatan partisipatif, demonstratif, dan pelatihan (learning by doing) melalui permainan edukatif kartu huruf serta kartu matematika (MathemaCard: Duel Berhitung); dan (3) Tahap evaluasi, untuk mengukur capaian kognitif serta observasi perilaku afektif. Teknik pengukuran hasil menggunakan instrumen pre-test dan post-test sederhana serta wawancara singkat . Hasil kegiatan menunjukkan peningkatan signifikan pada skor rata-rata literasi (25% menjadi 75%) dan numerasi (20% menjadi 70%). Selain aspek kognitif, media ini efektif meningkatkan rasa percaya diri, motivasi belajar, dan keterampilan sosial anak. Media ini merupakan solusi inovatif yang mudah direplikasi untuk komunitas lokal.
