Judul: The Development of Conservation in Southeast Asia: Focus on History, Policies and Institutions, and Current Conditions
Abstrak: Konservasi menjadi kata kunci utama dalam penelitian ini. Data dan informasi adalah sumber daya dan merupakan deskripsi fakta sekaligus insight di dalamnya. Penelitian ini menginvestigasi data dan informasi yang terdokumentasi dengan baik dalam literatur yang membahas konservasi di Asia Tenggara (SEA), terutama riset akademik dan laporan resmi dari organisasi yang berwenang. Penelitian ini menyoroti semua literatur potensial, memilahnya dengan seksama, memperoleh tabulasi sebagai database baru konservasi SEA dan mengidentifikasi dokumen yang memiliki potensi untuk menjadi relevan dalam penelitian ini. Melalui sintesis dan penilaian kritis terhadap literatur, penelitian ini merumuskan deskripsi perkembangan dari kawasan SEA (sejarah konservasi regional), kebijakan dan institusi, dan kondisi saat ini, baik di wilayah regional dan negara-oleh-negara yang tercatat sebagai anggota ASEAN. Hasil penelitian memberikan sorotan dan insight terhadap konservasi di tingkat regional dan nasional. Temuan kunci meliputi hutan sebagai warisan masa depan, yaitu bagian dari nilai dan sistem yang hidup dalam memori kolektif kehidupan manusia, supremasi kebijakan dan kelembagaan, lingkungan sebagai aset dan sumber daya, rekognisi sebagai penghargaan dan sarana promosi, dan konservasi sebagai tindakan kolektif., Conservation is the keyword of this research. Works of every data and information are resources, is a description of facts and an insight from within. This research investigates well-documented information in the conservation in Southeast Asia (SEA)'s literature, especially academic research and formal reports from authorized organizations. The study also features a country-by-country analysis that identifies where targeted information is needed. This research highlights all the potential literature, sorts it carefully, obtains a tabulation as a new database of SEA conservation, and identifies documents that have the potential to be relevant. Through synthesis and critical assessment of the literature, this research formulates a description of development from a regional SEA (regional history of conservation), policies and institutions, and current condition, both in SEA and a country-by-country within the ASEAN. The results highlight conservation at the regional and national levels as well as give insight for them. The key findings showed forest as a legacy for the future, namely part of the values and systems that live in the collective memory of human life; the supremacy of policies and institutions; the environment as an asset and resource; recognition as a reward and means of promotion; and conservation as a collective action.

Judul: Indonesian Women in Conservation: A Systematic Review on Roles, Motivation, Challenges, and Opportunities of Women Practitioners
Abstrak: Kontribusi perempuan terhadap upaya konservasi sudah mendapatkan pengakuan global, namun pengakuan atas kontribusi mereka di Indonesia masih terbatas. Penelitian ini menggunakan teknik tinjauan sistematis untuk menyelidiki partisipasi praktisi perempuan Indonesia dalam konservasi. Penelitian ini bertujuan untuk: (1) Mengkategorikan pustaka tentang praktisi konservasi perempuan dan memahami pola partisipasi mereka di Indonesia, (2) Mengidentifikasi peran, motivasi, tantangan, dan kesempatan praktisi perempuan di Indonesia, dan (3) Mengidentifikasi realita praktisi perempuan di konservasi. Sebanyak 44 jurnal direview dan ditemukan bahwa pengalaman perempuan dipengaruhi oleh norma sosial, struktur sosial, dan kesenjangan etnis. Peran produktif perempuan menunjukkan keragaman akibat kondisi budaya dan geografis, sehingga membentuk partisipasi di lingkungan perdesaan, perkotaan, dan adat. Motivasi perempuan dipengaruhi oleh ketergantungan mereka pada sumber daya alam dan komitmen terhadap keberlanjutan dan ditemukan kendala seperti prasangka gender dan kesenjangan dalam akses dan kontrol. Peningkatan kolaborasi antar sektor dan penerapan kebijakan berdasarkan kondisi lokal diperlukan untuk memfasilitasi kesetaraan gender untuk mencapai tujuan konservasi berkelanjutan., Women's contribution to conservation efforts is gaining global recognition, but the recognition of their contributions in Indonesia remains limited. This study used a systematic review technique to investigate the involvement of Indonesian women practitioners in conservation. The research aims to: (1) Classify literature on women conservation practitioners and analyse their patterns of participation in Indonesia, (2) Identify Indonesian women conservationists' roles, motivations, challenges, and opportunities, and (3) Identify the reality for Indonesian women as practitioners. As many as 44 journals were reviewed. The findings revealed societal norms, social structures, and ethnic disparities shape the range of women's experiences. Women's productive roles varied based on cultural and geographical circumstances, influencing their involvement in rural, urban, and indigenous environments. Women’s motivations were affected by their reliance on natural resources and commitment to sustainability, but they encountered obstacles such as societal standards, gender prejudice, and discrepancies in access and control. The promotion of collaboration across different sectors and implementation of policy changes specifically designed for local circumstances are needed to facilitate gender equality to reach sustainable conservation goals.

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
