Abstract

The purpose of this study is to critique the epistemology of Islamic education in the 21st century, analyze existing problems, and propose alternative solutions. This research employs a qualitative approach, using descriptive analysis methods and a literature review to explore various discussions on the epistemology of Islamic education. Data is validated through source triangulation and then analyzed through collection, presentation, and conclusion drawing. The findings indicate that, despite rapid advancements in education due to technology and globalization, there remain unresolved issues. Critiques of Islamic education epistemology still focus on the dominance of source and tool aspects in studying Islamic epistemology, which tends to be static and non-exploratory. Proposed solutions include an emphasis on empirically-based epistemology, theoretical intellectual knowledge, and a focus on student creativity. Furthermore, in the development of Islamic education curriculum, aspects that are dogmatic and transcendental need to be connected with the empirical world. This research has limitations in terms of scope and depth of analysis, but it has practical implications for the development of more relevant and contextual Islamic education.

Abstract

Pongamia (Pongamia pinnata) is a non-food plant that has the potential to be developed as a biofuel because its seeds’ oil content is up to 40%. Therefore, it is necessary to study the characteristics of seeds for germination in relation to mass cultivation and information on oil content as a production consideration. This paper aimed to describe the sensitivity of pongamia seed moisture content to germination and its oil content and also to understand the seed category. Variations in moisture content were obtained from storing seeds at ambient temperature for up to 5 months. Moisture content, morphological characters, oil content, and germination rate were examined for each storage period. Data were analyzed using analysis of variance to determine the treatment effect. The results showed that storing seeds at ambient temperature caused a decrease in moisture content. A decrease in moisture content of 29.36% in the first month’s storage significantly affected the reduction of morphological characters and seed weight. Meanwhile, during the 2–5 months storage period, the decrease in moisture content was only 2–5% and did not affect seed length. Reducing moisture content (MC) increased oil recovery but was not statistically significant. The best germination rate was 84.67%, obtained from fresh seeds (MC of 46.64%); the germination rate decreased as the moisture content decreased during storage. Pongamia should be categorized as an intermediate seed based on the seed moisture content characteristics and germination test results.

Abstract

Kilemo (Litsea cubeba (Lour.) Pers.), a forest tree species of the Lauraceae family, is naturally distributed in China, Taiwan, and Southeast Asia, including Indonesia. This species is valued for its high-quality essential oils and its potential applications in the biopharmaceutical and chemical industries. However, the semi-recalcitrant nature of kilemo seeds presents challenges in storage and germination, necessitating research to optimize seed quality and propagation methods. This study aims to evaluate the physical and physiological qualities of kilemo seeds sourced from highland regions in West Java and North Sumatra and to determine the best pretreatment methods to enhance germination performance. Seed samples were collected from Ciwidey, Mount Papandayan (West Java), and Aek Nauli (North Sumatra). The study assessed seed moisture content, purity, 1,000-seed weight, and seed viability. Different soaking treatments (plain water, boron solutions, KNO3 solutions, and coconut water) were applied, followed by germination tests under two sowing conditions: open seedbeds and plastic-covered seedbeds. The results indicate that kilemo seeds exhibit moisture content ranging from 13.01% to 14.68%, purity above 96.77%, and a weight of 1,000 seeds varying from 21.36 to 27.86 g. Germination trials revealed that seeds soaked in 100% coconut water for 3 or 6 hours exhibited the highest germination percentages and vigor, particularly in an open seedbed condition. These findings suggest that coconut water pretreatment enhances seed germination and viability, offering an effective method for improving the propagation success of kilemo. The study provides valuable insights into optimizing seed handling techniques to support the conservation and commercial cultivation of this species.

Abstract

This study aims to analyze the diversity of mangrove species in the Baros Beach mangrove ecosystem, Bantul, Yogyakarta, using the Shannon-Wiener diversity index method. Observations were conducted at five stations using line transect sampling, species identification, and measurements of environmental parameters such as temperature, salinity, pH, and light intensity. Five mangrove species were identified: Rhizophora mucronata, Bruguiera gymnorrhiza, Avicennia marina, Nypa fruticans, and Sonneratia sp. The Shannon-Wiener index value (H') was 1.288, indicating a moderate level of species diversity. This diversity is influenced by substrate variation—including muddy, sandy, and mixed types—and local environmental conditions across observation points. Muddy substrates rich in organic matter generally support higher mangrove density. These findings suggest that the Baros Beach ecosystem is relatively stable but still requires ongoing conservation efforts to sustain its biodiversity and prevent environmental degradation. Engaging the local community in protection and routine monitoring is essential for ensuring effective long-term mangrove ecosystem management.
