Judul: Potential Location and Health Response of  Healing Forest in Bogor Botanical Gardens
Abstrak: Perkembangan teknologi telah menyebabkan peningkatan urbanisasi dan kepadatan penduduk yang dapat memengaruhi kualitas hidup dan kesehatan mental. Pemulihan kesehatan mental dapat dilakukan dengan memanfaatkan ekosistem hutan sebagai healing forest. Penelitian ini bertujuan untuk menentukan lokasi potensial dan respon kesehatan dari healing forest di Kebun Raya Bogor. Penentuan lokasi dilakukan dengan tiga tahap yaitu analisis spasial, pengukuran parameter biofisik lingkungan, dan pengukuran parameter kesehatan. Hasil penelitian menunjukkan Kebun Raya Bogor dapat dikembangkan sebagai lokasi healing forest dengan memilih kondisi pagi hari, karena kondisi pagi menunjukkan nilai yang paling ideal dibandingkan dengan kondisi waktu lainnya. Aktivitas healing forest dapat menurunkan tekanan darah, menurunkan denyut jantung, menurunkan tingkat stres, dan meningkatkan saturasi oksigen. Terdapat perubahan yang signifikan dari setiap respon kesehatan saat sebelum dan sesudah melakukan healing forest kearah ideal (p<0,05). Hal ini menunjukkan bahwa berinteraksi dengan alam dan menghabiskan waktu di hutan dapat memberikan manfaat bagi kesehatan fisik dan mental., The development of technology has led to increased urbanization and greater population density that can affect the quality of life and mental health. Mental health recovery can be achieved by utilizing the forest ecosystem as a healing forest. This research aimed to determine potential locations and health response of healing forest in Bogor Botanical Gardens. The determination of locations was done through three stages, which are spatial analysis, measurement of biophysical environmental parameters and measurement of health response. Results found that Bogor Botanical Gardens can be developed as healing forest site by selecting morning conditions, as the most ideal time. Healing forest activities can lower blood pressure, reduce heart rate, decrease stress levels, and increase oxygen saturation. There were significant changes in each health response before and after participating in the healing forest towards the ideal condition (p<0.05). This indicates that interacting with nature and spending time in the forest can provide benefits for both physical and mental health.

Judul: The Potential of Healing Forest Area On the Darmaga Campus of IPB
Abstrak: Healing forest menjadi kegiatan yang populer pada masyarakat perkotaan pada saat ini khususnya yang sedang mengalami stres atau sekedar untuk mencari ketenangan diri di daerah hutan kota. Kegiatan healing forest memberikan efek relaksasi pada tubuh, menenangkan pikiran dan memberikan perasaan nyaman yang berimplikasi pada penurunan tingkat stres pada tubuh. Penelitian ini bertujuan untuk menginventarisasi potensi biofisik untuk kegiatan healing forest di masing-masing spot/area, mengidentifikasi aktivitas healing forest yang dapat dikembangkan di masing-masing spot/area serta melakukan penataan area untuk keperluan healing forest pada hutan kampus IPB Darmaga. Metode yang digunakan dalam penelitian ini adalah survei lapang dan wawancara terhadap masyarakat kampus IPB. Data yang diperoleh selanjutnya dianalisis menggunakan metode deskriptif kualitatif. Hasil penelitian menunjukkan terdapat tiga lokasi yang layak yaitu Arboretum Lanskap, Hutan Bambu dan Arboretum Lanskap. Kegiatan yang dapat dilakukan berdasarkan analisis lokasi dan preferensi masyarakat adalah berjalan-jalan di hutan, memeluk pohon serta menikmati suasana alam yang ada., Healing forest becoming a popular activity in urban communities at this time, especially those who are stressed or just to find peace of mind in urban forest areas. This activities provide a relaxing effect on the body, calm the mind and provide a comfortable feeling which has implications for reducing stress levels in our body. This study aims to take an inventory of the biophysical potential for healing forest activities in each spot/area, identify healing forest activities that can be developed in each spot/area and to organize areas for healing forest purposes in the forests of IPB Darmaga campus. This research use a field survey method and interviews with the IPB campus community. Data obtained were analyzed using a qualitative descriptive method. The results showed that there were three feasible locations, namely the Landscape Arboretum, Bamboo Forest and Landscape Arboretum. Activities that can be carried out based on location analysis and community preferences are walking in the forest, hugging trees and enjoying the natural atmosphere.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
