Abstract

The application of green banking (GB) practices can be a solution to various environmental problems and help achieve the SDGs. However, the performance of GB implementation in Indonesia’s Islamic Bank is still unclear due to the unavailability of instruments to measure its implementation. Even though information regarding GB implementation in Indonesia’s Islamic bank is urgently needed to achieve the SDGs and sharia goals or maqasid sharia. This study aims to develop index for measuring GB performance in Islamic Bank using maqasid syariah and ESG as framework, namely green banking maqasid index or GBMI. Model development and weighting in this study use the Delphi-ANP (Analytic Network Process) method. The results of this study reveal the order of priority and weight of variables related to GBMI measurement. There are 6 main priorities out of 18 important variables in ESG and their weights, namely green human resource management (HRM) (0.075), health and safety of the workplace (0.072), green product and service (0.070), green strategic planning (0.069), and elimination of wastage (0.065). These results also indicate that green HRM is among the most emphasized variables in the application of GB concept. Thus, educating HRM to understand the GB concept well is quite important in the initial stage of implementing GB practices in Islamic banks.

Abstract

Cadmium (Cd) heavy metal pollution not only affects aquatic ecosystems but also has toxic effects on human health. Bioremediation using microalgae Nannochloropsis sp. is considered more economical and sustainable for overcoming heavy metal pollution. This study aims to molecular characterization of Nannochloropsis sp. with tufA gene markers, determine the effect of different Cd concentrations on the growth and morphology of Nannochloropsis sp. and the ability of Nannochloropsis sp. to absorb Cd concentrations. The methods used include DNA isolation, quantitative and qualitative DNA analysis, amplification of tufA gene, sequencing result analysis, phylogenetic tree analysis, and bioremediation test. The results of molecular characterization showed that Nannochloropsis sp. has similarities with N. oceanica strain BR2 plastid (CP044614.1) with 60% bootstrap value. Nannochloropsis sp. grew at different Cd concentration (0, 2, 4, and 6 ppm) but optimal at 0 ppm Cd concentration. Morphology of Nannochloropsis sp. showed morphological differences in the cell structure. The cell was broken and the color turned increasingly clear. Different concentrations of Cd metal on Nannochloropsis sp. growth significantly affected the decline in Nannochloropsis sp. growth. Nannochloropsis sp. has the potential to absorb heavy metal Cd with an efficiency that increases as the concentration reaching 62.6% at 6 ppm. It can be concluded that molecular characterization using the tufA marker was effective in showing that Nannochloropsis sp. had closed relation with N. oceanica strain BR2 plastids. Cadmium (Cd) exposure significantly reduced growth and caused cell damage, while Nannochloropsis sp. effectively adsorbed Cd and lowering Cd levels by 3.76 ppm.

Abstract

Heavy metal lead (Pb) pollution in aquatic environments poses a serious threat to aquatic ecosystems and human health. The microalga Thalassiosira  sp. has potential as a bioremediation agent for heavy metals; however, further studies are needed to maximize its capability. This study aims to molecularly characterize Thalassiosira  sp. using the tufA gene, evaluate the effects of Pb on growth and cell morphology, and assess its Pb uptake efficiency. Methods included DNA isolation, phylogenetic analysis, growth measurement using a hemocytometer, Pb uptake testing via ICP-OES, and cell morphology analysis. Results showed that the tufA gene could molecularly characterize Thalassiosira  sp., with a phylogenetic similarity of 99.53% to Conticriba weissflogii (MH571875.1). Pb significantly inhibited growth at concentrations of 0.03 ppm and 0.05 ppm and caused cell aggregation and pigment degradation at higher concentrations (2 ppm). This microalga exhibited the highest Pb uptake efficiency at lower concentrations (0.03–0.05 ppm), reaching 100%, while at 2 ppm, the efficiency decreased to 40%. This study highlights the potential of Thalassiosira  sp. in remediating Pb, providing a foundation for the development of microalgae-based biotechnological applications.

Abstract

This research is motivated by the low learning outcomes of students in the subject of Islamic Religious Education (PAI), especially in the mastery of dhuha, tahajud, and Friday prayer materials in grade IV of SD Negeri 1 Tunahan. The purpose of the study is to analyze the improvement of student learning outcomes through the application of the Problem Based Learning (PBL) model and describe the implementation of the model along with its supporting and inhibiting factors. The research uses a Classroom Action Research (PTK) approach with a two-cycle design that includes the stages of planning, implementation, observation, and reflection. The research subjects consist of 15 grade IV students in the 2024/2025 school year. Data was collected through learning outcome tests, observations, interviews, questionnaires, and documentation, then analyzed descriptively, qualitatively, and quantitatively. The results showed a significant improvement: learning completeness increased from 33% in the pre-cycle to 87% in the second cycle, accompanied by an increase in the activity of teachers (average 4.9) and students (average 3.8) who were categorized as satisfactory and good, respectively. The PBL model has been proven to be effective in creating active, interactive, and contextual learning, thereby strengthening students' understanding of PAI materials. These findings make an original contribution to the application of a problem-based approach to religious learning in primary schools, while offering an alternative to relevant and applicable learning strategies.
