Constructivism learning theory places learners as active subjects in constructing knowledge through learning experiences, social interactions, and reflection on their surroundings. This approach views learning not as a passive process of receiving information, but as an active process of constructing meaning based on the prior knowledge possessed by learners. This paper aims to comprehensively examine the development and definition of constructivist learning theory, its main principles and characteristics, and its implications in the learning process, particularly in the context of primary education. The writing method used is a literature study by analyzing various literature sources in the form of textbooks, scientific journal articles, and other relevant references related to constructivism theory. The results of the study show that constructivist learning emphasizes learner-centered learning, where knowledge is not transferred directly by the teacher but is constructed through a process of assimilation and accommodation. In this approach, teachers act as facilitators who design a conducive learning environment so that students are able to build understanding independently and through social interaction. The application of constructivist learning has been proven to encourage the development of critical thinking, problem solving, cooperation, and meaningful learning. Therefore, constructivist learning theory is relevant to be applied in modern learning as an effort to improve the quality of the learning process and outcomes of students.

This article examines the conceot of knowledge (ilmu) within the Islamic perspective, which holds a highliy privileged position, ranking second only to the word Tauhid (Monotheism) in Islamic teachings. his paper employs a Library Research methodology (kajian pustaka). his approach involves the assimilation, study, and in-depth analysis of various readings utilized by the author. he presence of knowledge and education profoundly influences the development of human life concepts. In the Qur'an, the word "ilmu" (knowledge/science), in its various forms, in Quran, testifying to the distinctiveness of humans as caliphs on earth. Literally, "ilmu" is defined as knowing or to know, while technically it means understanding the reality of something or the rule governing it. The ultimate source of knowledge is Allah SWT. The process of teaching knowledge from Allah can be direct (revelation/inspiration or wahyu/ilham) or indirect (through the medium of natural phenomena He created). Knowledge acquisition can be achieved through several approaches, including: practice (pengamalan), experience (pengalaman), rational (rasional using intellect/reason), emotional, and habituation (pembiasaan). Islamic scholars have classified knowledge based on its object of study and source. For instance, Ibn Sina categorized knowledge into three types: al-‘ilm al-ilahi (divine and metaphysical knowledge), al-ilm al-riyahi (mathematics), and il-‘ilm tabi’I (natural sciences). Al-Ghazali classified it into ilmu shariah and ilmu gayr al-shari’ah, which aligns with Ibn Khaldun’s division of ilmu naql (transmitted knowledge) and ilmu aqal (intellectual knowledge). This division is based on the object of study, not meant to be contradictory.

This study analyzes the impact of urban sprawl on groundwater reserves in Kendari City using the platform Google Earth Engine (GEE) with analysis period of 2000 and 2024. Urban sprawl is characterized by an increase in built-up land area estimated through the Normalized Difference Built-Up Index (NDBI), while groundwater reserves are projected through estimated baseflow groundwater runoff obtained from FLDAS ( Famine Early Warning Systems Network Land Data Assimilation System ) data. The results show a significant increase in NDBI values from 2000 to 2024, indicating a massive expansion of built-up areas. Conversely, baseflow values have decreased consistently, with the average baseflow decreasing from 0.00002685 kg/m²/s (2000) to 0.00001894 kg/m²/s (2024), reflecting pressure on the aquifer system due to reduced infiltration areas. Pearson correlation analysis revealed a significant weak negative effect between NDBI and baseflow in 2000 (r = -0.219; p-value = 0), which changed to a weak positive effect in 2024 (r = 0.126; p-value = 0), indicating a shift in hydrological dynamics due to the accumulated impacts of urbanization. This finding confirms that urban sprawl has reduced groundwater recharge capacity and threatened the sustainability of clean water supplies. The study recommends the need for sustainable spatial planning policies and groundwater conservation strategies to mitigate these negative impacts.

The purpose of this paper is to examine the role of Green Intellectual Capital (GIC) in the development of waste-to-energy (WtE) technologies, which is of special relevance for the incineration plants in the Gulf Cooperation Council (GCC) countries. Although previous studies have focused primarily on technological and infrastructural aspects, this paper investigates the contribution of intangible assets such as green human, structural, and relational capital towards the performance and sustainability of WtE systems. Adopting a mixed-method approach, the results show that Green Structural Capital has the first place in supporting operational efficiency, followed by Green Human Capital and Green Relational Capital. The statistical analysis based on Structural Equation Modeling (SEM) shows that all GIC dimensions are positively related to plant performance, with institutionalized knowledge and systems as the most significant enablers of innovation. Qualitative findings also highlight constraints such as lack of training, unhandy knowledge systems, and poor public-private interaction. The findings recommend policy suggestions for promoting GIC assimilation within environmental infrastructure and provide a region-based theoretical model connecting knowledge-based resources and sustainable waste management practices. The study emphasizes the importance of integrating intellectual capital into the strategic decision-making process of waste-to-energy plants to enhance their operational effectiveness and long-term sustainability. Additionally, the research underlines that fostering a knowledge-sharing culture and enhancing collaboration between various stakeholders, including governmental bodies, private firms, and research institutions, is critical for the success of green initiatives. Training programs aimed at developing green human capital and improving public-private partnerships are essential to overcoming the current barriers to innovation in the WtE sector. This study has practical and scholarly implications in unifying the focus from just technology to the facilitating role of human and intellectual capital in green transformation, further bridging the gap between environmental sustainability and technological advancements in waste management.

Bekasam is a traditional fermented fish-based food popular in various regions in Indonesia, including Batanghari, Jambi. This product is produced through a spontaneous fermentation process that utilizes the activity of microorganisms, particularly lactic acid bacteria (LAB), which play an important role in the formation of distinctive flavors, food safety, and potential health benefits. One type of fish used is lambak fish (Labiobarbus ocellatus), which is commonly found in local waters. Given the high prevalence of cardiovascular disease associated with cholesterol levels, exploring the probiotic potential of local fermented foods presents a strategic opportunity to support public health. This study aims to isolate and identify LAB from bekasam lambak fish from Mersam, Batanghari, and evaluate its initial potential as a candidate for cholesterol-lowering probiotics. The research method was carried out in the laboratory through a series of dilutions (10⁻¹–10⁻⁶) of bekasam samples, followed by cultivation on Nutrient Agar (NA) media using the pour and streak method. Incubation was carried out at 37°C for 24–48 hours. The growing colonies were then observed morphologically and tested using Gram staining. Observations revealed spherical, milky-white colonies with Gram-positive rod-shaped characteristics, indicating they likely belonged to the Lactobacillus genus. This genus is known to lower cholesterol through bile acid binding and free cholesterol assimilation mechanisms in the digestive tract. These findings reinforce the notion that bekasam lambak fish contains local LAB isolates that have the potential to be developed as a natural probiotic raw material. This potential can be utilized in the development of functional fermented food products or nutraceuticals that not only maintain the traditional value of bekasam but also provide preventative health benefits, particularly in controlling cholesterol levels.

The pursuit of inclusive mathematics instruction requires educators to adopt adaptive teaching approaches, with differentiated instruction (DI) emerging as a key component. This study explores how future mathematics teachers perceive DI, especially regarding their grasp of its core principles, confidence in instructional application, preparedness to implement, and perspectives on its advantages and obstacles. Employing a descriptive quantitative access, data were collected through a 50-item Likert-scale questionnaire administered to 25 mathematics education students from three universities in Indonesia. The findings affirm comprehensive favorable attitudes toward DI, with mean scores ranging between 3.98 and 4.01. Respondents advertised strong theoretical comprehension of DI and showed enthusiasm about integrating it into their teaching practices. However, challenges such as limited instructional time and deficient firsthand experience in crafting differentiated lessons were acknowledged. These acumen highlight the importance of assimilation more practical, experience-based training within teacher education programs to equip future educators for implementing inclusive and differentiated teaching effectively.

This study aims to examine the historical development of the science of shorof with a focus on the contribution of classical scholars to the systematics of Arabic morphology, especially in the infaʽala verb pattern. Using a qualitative approach and literature study methods, this study traces the linguistic thoughts of figures such as Sībawayh, al-Mubarrid, Ibn Jinnī, to al-Raḍī. The results of the study show that the majority of classical scholars determine the infaʽala pattern as a non-transitive verb (lāzim) that contains the meaning of muṭāwaʽah, and is closely related to the basic pattern of faʽala. In addition, there were restrictions on certain letters as basic letters in this pattern to avoid sound assimilation (idghām). This study confirms that the Arabic morphological system is built on regular and logical rules, and the contribution of classical scholars is very significant in laying the scientific foundations of the science of shorof which are still relevant today
