Abstract

Adolescence is a critical developmental period marked by rapid cognitive, emotional, and social changes that significantly influence learning processes and mental health outcomes. Cognitive development during this stage plays a central role in shaping adolescents’ academic engagement, self-regulation, and psychological well-being, yet it is often examined separately from educational and mental health perspectives. This study aims to investigate the role of cognitive development in adolescence and its implications for both education and mental health within an integrated framework. The research employed a quantitative cross-sectional design involving adolescents aged 13–18 years enrolled in secondary education. Data were collected using standardized instruments measuring cognitive development, educational engagement, and mental health well-being, and were analyzed using descriptive and inferential statistical techniques. The findings reveal significant positive relationships between cognitive development and educational engagement, as well as between cognitive development and mental health indicators. Adolescents with higher levels of cognitive functioning demonstrated stronger academic engagement and better emotional regulation. These results indicate that cognitive development functions as a key mechanism linking learning and mental health during adolescence. The study concludes that educational practices and mental health interventions should prioritize cognitive development as a foundational element.

Abstract

Reducing Emissions from Deforestation and Forest Degradation (REDD+) is a pivotal international climate change mitigation mechanism, with Indonesia being a key implementing country due to its vast tropical forests. Despite significant international investment, the economic viability and effectiveness of REDD+ in achieving its goals are contingent upon the design and implementation of national policies. This study aimed to conduct a comprehensive economic policy analysis of REDD+ implementation in Indonesia, evaluating its efficiency, cost-effectiveness, and the equity of its benefit-sharing mechanisms. A policy analysis framework was employed, integrating economic principles with a review of national and sub-national REDD+ policies, regulations, and project implementation documents from 2010 to 2024. The analysis was supplemented by a meta-synthesis of financial reports from REDD+ pilot projects and existing academic literature to assess transaction costs, financial flows, and benefit distribution. The analysis reveals significant economic challenges. High transaction costs, coupled with unclear carbon tenure and property rights, have created substantial inefficiencies and deterred private sector investment. Furthermore, the absence of a consistent national carbon price has undermined the financial incentives for land-use change. Benefit-sharing mechanisms were often found to be ad-hoc, leading to inequitable outcomes that failed to adequately compensate local communities for their opportunity costs. For REDD+ to become an economically viable and effective climate mitigation strategy in Indonesia, significant policy reforms are imperative. Future policies must focus on reducing transaction costs, providing clear and secure carbon tenure, and establishing transparent, equitable, and efficient benefit-sharing mechanisms that reflect the true costs borne by local stakeholders.

Abstract

The Standard Quantum Limit (SQL) sets a fundamental barrier on the precision of force sensing due to quantum fluctuations. Surpassing this limit is crucial for advancing the sensitivity of force sensors, especially in applications like gravitational wave detection and quantum metrology. This study explores the potential of squeezed light injection into cavity optomechanical systems to surpass the SQL in force sensing. The main objective is to develop a method that enhances the precision of force measurements by leveraging quantum squeezing, thereby reducing quantum noise in one quadrature of the light field. The research employs both theoretical modeling and experimental techniques to study the effects of squeezed light on the force sensitivity of a cavity optomechanical system. The system was tested with varying squeezing levels and optomechanical coupling strengths. Force sensitivity was measured using a heterodyne detection setup, with the results compared to the SQL. The findings demonstrate that force sensitivity can indeed surpass the SQL by utilizing squeezed light, with a significant improvement in precision observed at higher squeezing levels. At 12 dB of squeezing, the system achieved a sensitivity of 3.1 × 10?¹³ N/?Hz, well below the SQL. This research confirms that squeezed light injection, combined with optimized optomechanical coupling, is a viable technique for quantum-enhanced force sensing.

Abstract

The rise of antimicrobial resistance is a global health crisis, demanding the urgent discovery of novel antibiotics. Indonesian mangrove forests, as a unique and underexplored ecosystem, represent a promising frontier for bioprospecting novel microorganisms. The plant rhizosphere, a zone of intense microbial activity, is particularly rich in actinobacteria, a phylum renowned for its prolific production of bioactive secondary metabolites. This research aimed to isolate and characterize novel antibiotic-producing actinobacteria from the rhizosphere of Indonesian mangrove plants. Rhizosphere soil samples were collected, and actinobacteria were isolated using selective media. All isolates were screened for antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans via the agar well diffusion method. The most potent isolate was subsequently characterized using morphological, biochemical, and 16S rRNA gene sequencing. From 72 distinct isolates, 15 displayed antimicrobial activity. One isolate, designated MGR-17, demonstrated exceptionally potent, broad-spectrum inhibition against all tested pathogens. Based on polyphasic taxonomy, MGR-17 was identified as a potentially novel species of the genus Streptomyces. In conclusion, the rhizosphere of Indonesian mangroves is a fertile source for discovering unique actinobacteria capable of producing novel antibiotics, and the discovery of Streptomyces sp. MGR-17 underscores this potential.

Abstract

Agricultural waste has great potential to be used as biomaterial raw materials that can be used in medical applications, especially for bone tissue regeneration. Nanocellulose, which is produced from natural cellulose, offers good mechanical properties and high biocompatibility. This research aims to develop nanocellulose-based biomaterials from agricultural waste for bone regeneration applications. The purpose of this study is to explore the potential of agricultural waste, such as rice straw, peanut husks, and corn leaves, in producing high-quality nanocellulose that can be used for applications in the field of bone tissue regeneration. This study uses an experimental design with a laboratory approach. Agricultural waste is treated through nanocellulose extraction using certain chemical techniques. Material characterization was carried out using scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR), as well as biocompatibility tests using osteoblast cell cultures. The results show that rice straw produces nanocellulose with the highest cellulose content (65%) and has optimal tensile strength and degradation time for bone tissue applications. Peanut husks and corn leaves also show good results, although not as good as rice straw. Agricultural waste, especially rice straw, has great potential to be used as a raw material for nanocellulose that can be used in bone tissue regeneration applications. This research opens up opportunities to develop more sustainable and affordable biomaterials for medical applications.
