Abstract

Tubers are high-carbohydrate food ingredients that are widely available in Indonesia. However, not all tubers in Indonesia are used and developed optimally. Suweg is a tuber plant that can grow in yards or fields without special maintenance. Some farmers in Java, Sumatra, and Eastern Indonesia already know Suweg. Suweg is a very potential source of food. Suweg has prospects to be developed into tuber flour and starch. Suweg, which belongs to the taro tribe, is being looked at by several groups in the food and health supplement industry as a raw material because of its nutritional content. In this study, tubers of suweg were processed into intermediate products in the form of suweg flour using a modified salt solution immersion method and fermentation using a lactic acid bakery starter (BAL). The resulting suweg flour is brownish-white powder, clean from other impurities, with a distinctive suweg odor and a slightly characteristic suweg taste and passes through an 80-mesh sieve. The economic simulation results in producing 85.8 kg of suweg flour for 1 month packaged in 1 kg obtained a base price of Rp. 4,290,000, R/C ratio of 1.3, BEP volume of 39.55 packages, BEP price of Rp. 1,977,660. Keywords: tubers, suweg flour, intermediate products, lactic acid bacteria

Abstract

Black soybean germination into sprouts reportedly improved nutrition digestibility and bioactive compound content. Red dragon fruit (RDF) and egg yolk (EY) can be used as natural and halal colorants and emulsifiers. Black soybean sprout (BSS) juice made non-dairy ice cream with red dragon fruit and egg yolk as an emulsifier. This research aimed to measure the effect of various red dragon fruit and egg yolk concentrations on the characteristics of ice cream made from BSS juice. A completely randomized design was applied to six formulations made using the ratio of RDF : EY of FA (20%: 3%), FB (20%: 4%), FC (20%: 5%), FD (40%: 3%), FE (40%: 4%), and FF (40%: 5%). BSS juice was made using 48 hours of room temperature incubated sprout and water at a 1:4 (b/v) ratio. Filtrate was then mixed with sugar, cornstarch, and salt into a dough, which was then mixed with RDF and EY at various concentrations. Nutritional proximate composition, radical scavenging activity, phenolic content, total anthocyanin content, vitamin C, and sensory acceptance were analyzed. Data was then statistically analyzed using one-way ANOVA, followed by Duncan’s Multiple Range Test. Results showed that higher RDF significantly changed overrun, melting rate, increased moisture content, vitamin C (20.4 – 40.23 mg/100 g), antioxidant activity (34.9 – 62.78 % radical scavenging activity), total phenolics (0.341 – 0.536 mg/g GAE), and total anthocyanin (3.905 – 9.726 mg/kg), and hedonic score, but shorter melting time. The shortest melting time was obtained by ice cream made using 20% RDF and 5% EY, the lower concentration of fruit, and the highest concentration of egg yolk, respectively. The results indicated that BSS juice could be used as the main ingredient to make non-dairy ice cream, with red dragon fruit and egg yolk as natural colorants and emulsifiers, respectively.   Keywords: Black soybean sprout, Non-dairy ice cream, Red dragon fruit

Abstract

Memorizing the Qur’an (tahfidz) constitutes a fundamental practice within Islamic education that integrates spiritual discipline with complex cognitive mechanisms. This study investigates the role of long-term memory in tahfidz learning through a cognitive neuroscience framework. Employing a literature review approach, the analysis synthesizes scholarly sources in neuroscience, cognitive psychology, and Islamic pedagogy to elucidate how memory processes—encoding, consolidation, storage, and retrieval—operate in Qur’anic memorization. The reviewed evidence indicates that neural structures including the hippocampus, prefrontal cortex, medial temporal cortex, and amygdala play essential roles in organizing, stabilizing, and retrieving memorized verses. Empirical findings also support the effectiveness of strategies such as spaced repetition, mushaf-based visual mapping, semantic association, and mnemonic patterning in strengthening synaptic connectivity and retention. Furthermore, emotional regulation and spiritual engagement are shown to facilitate memory consolidation via activation of the limbic system, while restorative sleep, peer interaction, and collaborative learning in halaqah settings enhance long-term recall. Collectively, these insights demonstrate that tahfidz represents a holistic neurocognitive process that synergistically integrates devotional motivation, affective states, and memory system dynamics. The study underscores the pedagogical significance of developing neuroscience-informed tahfidz methodologies that align cognitive, emotional, and spiritual elements within instructional design. Future research opportunities include experimental neuroeducation models to quantitatively evaluate the efficacy of memory-enhancement protocols in broader Islamic learning contexts.

Abstract

This study investigates the effect of citric acid (CA) and 4-carboxyl-3-chlorobenzeneboronic acid (CBBA) ratio on the Quantum Yield (QY) of Graphene Quantum Dots (GQDs). The hydrothermal synthesis method was employed with various CA/CBBA molar ratios, and the optical properties were analyzed using UV-Vis and photoluminescence (PL) spectroscopy. The results show that increasing the CBBA ratio enhances fluorescence efficiency, with the highest QY of 5.075% obtained at a 1:5 ratio. The addition of CBBA improves surface passivation and reduces non-radiative recombination sites, thereby optimizing the photoluminescence properties. Furthermore, precursor ratio variation influences particle size and functional groups, affecting the solubility and stability of GQDs. These findings highlight the role of CBBA in controlling exciton recombination, making GQDs more efficient for optoelectronic, bioimaging, and biomedical applications. Further studies are needed to explore the long-term effects of CBBA doping on fluorescence stability

Abstract

This study investigates the solubility behavior of water molecules on the surface of CuInS₂/ZnS Quantum Dots (QDs) in different solvents using an Ab Initio approach based on Density Functional Theory (DFT). The research evaluates the influence of solvent dielectric constant on surface potential energy and solute-solvent interaction energy. The study reveals that hydrogen bonding, dipole-dipole interactions, and van der Waals forces significantly affect QDs stability and size. The findings indicate that solvents with higher dielectric constants destabilize nanoparticles, leading to electron transfer between particles. Among the tested solvents, chloroform provides an optimal balance between solubility, stability, and band gap (~1.68 eV). These results contribute to a deeper understanding of solvent-mediated effects on QDs, essential for their application in optoelectronics and bio-imaging.

Abstract

Municipal solid waste remains a pressing environmental challenge in the Special Region of Yogyakarta (DIY), characterized by the continuous increase in waste generation, limited waste-management infrastructure, and low levels of public awareness and participation. This study aims to identify and analyze public perceptions and attitudes toward waste management across the five administrative regions of DIY through the distribution of 250 questionnaires administered using a random-sampling technique. The collected data were examined using descriptive statistics, k-means clustering, and heatmap visualization. The findings indicate significant variations in awareness and participation levels based on demographic factors such as age, gender, educational background, occupation, and residential area. The clustering analysis categorized respondents into three groups low awareness (34%), moderate awareness (25%), and high awareness (41%) each requiring different forms of intervention. Beyond the social dimension, the results demonstrate that Islamic ethical principles such as cleanliness as part of faith, the prohibition of environmental destruction (fasād), and the human responsibility as khalifah (stewards of the Earth) serve as an ethical and spiritual foundation that can reinforce community-based waste-management initiatives. Overall, the study concludes that addressing the waste crisis in Yogyakarta requires more than infrastructural solutions; it demands cultural transformation, continuous environmental education, and cross-sector collaboration to build collective ecological awareness and sustainable public engagement.

Abstract

Learning motivation is a fundamental element in the success of higher education, especially in entrepreneurship courses that require creativity, innovation, courage to take risks, and mental toughness. This study aims to analyze the contribution of Islamic psychology concepts in increasing student learning motivation in entrepreneurship learning in Islamic higher education institutions. This study uses a descriptive qualitative method through classroom observation, semi-structured interviews, and learning reflections on students from eight undergraduate programs at Ahmad Dahlan University, namely Psychology, Law, Information Systems, Food Technology, English Literature, Biology, Pharmacy, and Medicine. The results of the study indicate that the integration of Islamic psychological values, including fitrah, religious motivation, tazkiyatun nafs, work ethics, and the concept of ikhtiar tawakal, plays a significant role in increasing student learning motivation, both quantitatively (discipline, participation, and project completion) and qualitatively (deepening the meaning of learning, work ethic, courage to innovate, and resilience in the face of failure). A relatively consistent positive response was found in all study programs, but with nuances of internalization that differed according to the characteristics of each discipline. These findings emphasize the importance of developing an Islamic psychology-based entrepreneurial learning model to produce Muslim entrepreneurial graduates who are competent, have integrity, are resilient, and are oriented towards social benefit.

Abstract

The stability of drugs and nanocarriers is a crucial factor in guaranteeing their efficacy and quality. Nanostructured lipid carriers (NLCs) as lipid-based nanocarriers provide benefits in overcoming the stability and other issues associated with the drug. Surfactants play a crucial role in imparting the desired characteristics of lipid based systems, including stability, particle size, size distribution, and zeta potential. This study aimed to develop a capsanthin-loaded NLC formulation with an optimal surfactant combination that exhibits the required properties and stability. Three formulations were prepared applying Tween 20 and Span 80 in ratios of 5:1, 2:1, and 1:1 for F1, F2, and F3, respectively. Capsanthin, as an active ingredient, originates from paprika powder. NLC properties regarding transmittance, particle size, polydispersity index (PI), zeta potential, loading capacity (LC), and loading efficiency (LE) were characterized. Furthermore, stability studies were also conducted in this research. The results showed that F1 exhibited desirable characteristics, including transmittance percentage, particle size, PI, zeta potential, LC, and LE of 87.22±2.64%, 255.4±46.88 nm, 0.54±0.13, -39.51±3.02 mV, 12.59±0.35%, and 35.40±3.07%, respectively. Moreover, the physical stability studies exhibited that F1 provided a more stable system compared to other formulations. Additionally, the chemical stability indicated that degradation occurred in the paprika powder, not in the NLC. In conclusion, NLC can protect capsanthin, as evidenced by the stable capsanthin levels in NLC compared to those in paprika powder.
