Penelitian ini bertujuan untuk menyusun perencanaan jalur interpretasi di kawasan TNGHS Resort Pengelolaan Taman Nasional (RPTN) Kawah Ratu. Pengumpulan data untuk penelitian ini dilaksanakan di jalur trekking Kawah Ratu RPTN Kawah Ratu pada bulan September 2023. Metode pengumpulan data yang digunakan dalam penelitian ini meliputi wawancara, observasi lapangan, dan studi literatur. Tema interpretasi yang diangkat pada perencanaan interpretasi ini adalah “Kekayaan alam di rimba Kawah Ratu yang memesona dan memiliki manfaat kesehatan bagi masyarakat”. Objek interpretasi yang dipilih terbagi ke dalam 3 aspek, yaitu objek fisik (Kawah Ratu, batuan Kawah Ratu, dan Sungai Cikuluwung), objek biologi berupa tumbuhan (harendong bulu, paku, tepus, aren, rasamala, saninten, pinus, puspa, damar, begonia, cantigi, dan cangkuang) dan satwa (elang jawa, lutung budeng, owa jawa), serta objek sosial budaya (kuliner Sunda dan cerita mitos di jalur Kawah Ratu). Objek interpretasi disajikan dalam skenario cerita dan peta interpretasi jalur Kawah Ratu., Mount Halimun Salak National Park area has diverse tourism resources ranging from endemic plants and animals to various natural attractions, one of which is Kawah Ratu site located in Sukabumi Regency. This study aimed to develop an interpretation trail planning in the Kawah Ratu National Park Management Resort (RPTN) TNGHS area.

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
