Judul: Evaluation of Climate Change Adaptation Related Programs in Indonesia
Abstrak: Indonesia telah menunjukkan komitmen yang kuat dalam mengatasi perubahan iklim, terutama melalui aksi adaptasi. Komitmen ini tercermin dalam ratifikasi berbagai perjanjian internasional dan pengembangan Nationally Determined Contribution (NDC). Namun, pengukuran capaian adaptasi masih menghadapi tantangan karena kurangnya kerangka kerja yang terpadu dan keterbatasan sumber daya. Penelitian ini bertujuan untuk mengevaluasi capaian aksi adaptasi perubahan iklim yang dilakukan oleh Pemerintah Indonesia, terutama dalam merespons dampak perubahan iklim pada sektor bencana. Penelitian ini menggunakan analisis risiko iklim komprehensif dan kerangka kerja Tracking Adaptation and Measuring Development (TAMD) untuk menilai manajemen risiko iklim dan implementasi aksi adaptasi. Hasil penelitian menunjukkan bahwa capaian manajemen risiko iklim masih perlu ditingkatkan, terutama dalam hal pendanaan. Program Kampung Iklim (Proklim) memiliki capaian terbaik, namun semua program menghadapi kendala pendanaan. Evaluasi juga menunjukkan keterbatasan data dan indikator untuk mengukur hasil implementasi aksi adaptasi. Hasil penelitian ini diharapkan dapat meningkatkan sinergi antara pemangku kepentingan dan memperkuat mekanisme pendanaan untuk mendukung aksi adaptasi perubahan iklim secara berkelanjutan di Indonesia., Indonesia has strongly committed to addressing climate change, particularly through adaptation actions. This commitment is reflected in the ratification of various international agreements and development the Nationally Determined Contribution (NDC). However, measuring adaptation achievements remains challenging due to the lack of an integrated framework and limited resources. This study aims to evaluate climate change adaptation actions taken by the Government of Indonesia, especially in responding to climate change impacts on the disaster sector. This research uses a comprehensive climate risk analysis and Tracking Adaptation and Measuring Development (TAMD) framework to assess climate risk management and adaptation action implementation. The results show that climate risk management achievements still need to be improved, especially in terms of funding. The Climate Village Program (Proklim) has the best achievements, but all programs face funding constraints. The evaluation also showed limited data and indicators to measure the results of adaptation action implementation. The results of this research are expected to improve synergies between stakeholders and strengthen funding mechanisms to support climate change adaptation actions in a sustainable manner in Indonesia.

Judul: Tinjauan Hasil Kajian Kerentanan dalam Pengembangan Strategi Adaptasi di Indonesia Terkait Perubahan Iklim
Abstrak: The impact of climate changes going increasingly worrying. It put Indonesia as one of the most vulnerable countries affected by climate change. This study was conducted by reviewing the studies that have been done by DNPI focused on adaptation strategies to climate change in Indonesia. Especially to the vulnerability of food, health, and in coastal areas, which is expected to anticipate losses due to the impact of greater climate change. The development of adaptation strategies is a top priority that must be done, and the role of government in this case is The National Council on Climate Change (NCCC), it is necessary to formulate, coordinate and control the policies that is consistent with climate change adaptation. The cooperation of all parties to participate in controlling climate change makes it especially important considering the process of socialization and adaptation. It requires a synergistic follow-up between the government, private sector, NGOs to the general public. Adaptation strategies of the results of this study is also expected to reduce climate refugees due to climate change.

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
