Judul: Green Waqf Development Strategy for Protecting Indonesian Land Ecosystem: An ISM Approach
Abstrak: Permasalahan ekosistem darat di Indonesia salah satunya ialah adanya 14 juta lahan kritis melatarbelakangi terbentuknya Green Waqf di Indonesia pada 2021. Penelitian ini bertujuan mendeskripsikan program Green Waqf, mengidentifikasi dan menganalisis sub-elemen kunci strategi pengembangan Green Waqf dalam menjaga ekosistem darat di Indonesia melalui pendekatan Interpretive Structural Modeling. Hasil penelitian menunjukkan bahwa Green Waqf merupakan konteks baru di Indonesia dimana pemanfaatan wakaf sejalan dengan SDGs 13, 15 dan dalam jangka panjang dapat mencapai SDGs 7. Green Waqf merupakan salah satu proyek yang mendukung Green Finance dan Green Economy, sehingga diperlukan strategi untuk pengembangannya di Indonesia. Strategi yang diusulkan dalam penelitian ini adalah adanya payung hukum Green Waqf yang menjadi fondasi kuat pengembangan Green Waqf di Indonesia serta keterlibatan aktif dan koordinasi baik regulator, praktisi, dan akademisi dalam Green Waqf Framework di Indonesia., There are 14 million critical lands required for the establishment of Green Waqf in Indonesia in 2021. Through the use of Interpretive Structural Modeling, this study intends to characterize the Green Waqf program in Indonesia, identify and analyze essential sub-elements of the Green Waqf development strategy in managing terrestrial ecosystems in Indonesia. The results show that Green Waqf is a new context in Indonesia where the use of waqf is in line with the goals of SDGs 13, SDGs 15 and in the long term can achieve SDGs 7. Green Waqf is also one of the projects that supports Green Finance and Green Economy, so a strategy is needed for its development in Indonesia. As a firm foundation for the development of Green Waqf in Indonesia, the strategy put out in this study is the existence of a legislative framework for Green Waqf as well as the active participation and coordination of regulators, practitioners, and academics in the Green Waqf Framework in Indonesia.

Judul: Strategi Pengembangan Program Wakaf Hijau Berbasis Tamanu di Indonesia
Abstrak: Permasalahan lingkungan di Indonesia beberapa di antaranya mencakup krisis energi dan ancaman lahan kritis yang berdampak pada keanekaragaman hayati, iklim, polusi, dan deforestasi. Indonesia perlu solusi berkelanjutan seperti implementasi model wakaf hijau. Program wakaf hijau diterapkan dengan memproduktifkan lahan wakaf melalui tanaman, seperti Tamanu (Calophyllum Inophyllum). Di Indonesia, lembaga wakaf yang saat ini memiliki program wakaf hijau Tamanu, yaitu Sinergi Foundation dan Paramadina. Penelitian ini bertujuan merumuskan strategi pengembangan wakaf hijau Tamanu di Indonesia dalam rangka mendukung pembangunan berkelanjutan. Data dalam penelitian merupakan data primer yang didapat dari wawancara mendalam dan pengisian kuesioner kepada tujuh informan dan dianalisis dengan metode ANP-SWOT. Hasil penelitian menunjukkan bahwa aspek peluang menjadi prioritas paling tinggi dibanding aspek lainnya. Strategi yang dirumuskan, yaitu seperti menciptakan program kolaborasi dengan pihak-pihak yang fokus dalam isu lingkungan untuk pengembangan wakaf hijau Tamanu di Indonesia ke depannya. Perumusan strategi dapat menjadi rekomendasi kebijakan pelaksanaan lembaga wakaf yang menerapkan program wakaf hijau Tamanu., Environmental problems in Indonesia include the energy crisis and the threat of critical land that impacts biodiversity, climate, pollution, and deforestation. Indonesia needs sustainable solutions such as the implementation of a green waqf model. The green waqf program is implemented by producing waqf land through plants, such as Tamanu (Calophyllum Inophyllum). In Indonesia, the waqf institutions that currently have Tamanu's green waqf program are Sinergi Foundation and Paramadina. This research aims to formulate a Tamanu’s green waqf development strategy in order to support sustainable development. The data in the study is primary data obtained from in-depth interviews and filling out questionnaires to seven informants and analyzed by the ANP-SWOT method. The results showed that the opportunity aspect was the highest priority compared to other aspects. Strategies formulated, such as creating collaboration programs with parties who focus on environmental issues for the development of Tamanu green waqf in Indonesia in the future. The formulation of strategies can be a policy recommendation for the implementation of waqf institutions that implement the Tamanu green waqf program.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
