Abstract

Forests are ecosystems containing biological resources, primarily dominated by trees, that are interconnected and inseparable from their environment. Communities hold both the rights and responsibilities for forest management, as their livelihoods heavily depend on forests. One example of an indigenous community that continues to uphold traditional forest management based on local wisdom is the Dayak Wehea Indigenous People in Nehas Liah Bing Village, Muara Wahau District, East Kutai Regency. This study aims to explore the role and efforts of the Dayak Wehea community in preserving forest sustainability. The research employs a qualitative method with data collection techniques including observation, interviews, and documentation. The findings reveal that the Wehea Indigenous People have successfully preserved their forests through cultural values and local wisdom, despite facing various challenges such as economic pressures, limited external support, and low youth participation. This success demonstrates that environmental conservation relies not only on technology and government regulations but also on the empowerment of local communities, respect for ancestral values, and a strong spirit of mutual cooperation.

Abstract

In this paper, the dynamics of malaria transmission model in Panajam Paser Utara Regency are given. The SISI (Susceptible Human-Infected Human-Susceptible Vector-Infected Vector) model is used in this paper by assuming that the human population can be infected with malaria more than once. The model parameters are estimated based on monthly cumulative data of malaria cases in Panajam Paser Utara Regency in 2023-2024 using the Kalman Filter method. The simulation results show that the comparison of the estimated value and the actual value in cases of humans infected with malaria in Panajam Paser Utara Regency in 2023-2024 produces a MAPE of 6.27% so that it can be concluded that the level of forecasting accuracy is high because it is <10%. Furthermore, two controls are considered to minimize the spread of malaria, namely human contact prevention measures with mosquitoes and mosquito spraying. Then the dynamic optimization problem is solved using the Pontryagin Minimum Principle method. The goal is to reduce the population of infected humans and mosquitoes by minimizing the costs incurred for mosquito prevention and spraying. Numerical results are presented to show that both controls can effectively minimize the spread of malaria.

Abstract

Mahasiswa sarjana TAMA memiliki kemampuan yang berbeda-beda, hal ini disebabkan oleh pengalaman belajar yang diperoleh serta pola pikir yang bersifat hierarkis dari masing-masing individu. Alat yang digunakan untuk mengevaluasi respons mahasiswa adalah taksonomi SOLO. Penelitian ini bertujuan untuk memperoleh gambaran tentang kemampuan mahasiswa program studi Pendidikan Agama Islam dalam menyelesaikan masalah ukuran pemusatan data ditinjau dari taksonomi SOLO. Metode penelitian yang digunakan adalah penelitian kualitatif dengan pengambilan data dari hasil instrumen berupa tes kemampuan awal, tes materi, dan wawancara yang memuat indikator level SOLO. Berdasarkan tes kemampuan awal, mahasiswa dapat dikategorikan ke dalam level unistruktural, multistruktural, dan relasional. Hasil penelitian menunjukkan bahwa mahasiswa pada level unistruktural belum dapat memahami masalah dengan baik, yang ditunjukkan dengan hanya mampu menuliskan nilai rata-rata dari interval, sehingga tidak dapat menyelesaikan masalah. Mahasiswa pada level ini juga belum memahami materi. Berbeda dengan mahasiswa level multistruktural, mereka mampu menuliskan berbagai informasi dari soal seperti nilai rata-rata interval dan hasil perkalian antara frekuensi dengan nilai rata-rata interval. Namun, mahasiswa level ini belum mampu menjalankan rumus yang telah dituliskan karena terburu-buru. Selain itu, mereka juga kurang teliti dalam menuliskan simbol-simbol pada rumus nilai rata-rata. Sementara itu, mahasiswa pada level relasional dapat memahami masalah dengan baik. Mereka mampu menuliskan berbagai informasi dari soal dan menghubungkannya sehingga menghasilkan perhitungan dan kesimpulan yang benar.
