Type 2 Diabetes Mellitus (T2DM) has emerged as a critical global health threat driven by chronic insulin resistance and pancreatic beta-cell dysfunction. Conventional therapies often fail to address the underlying molecular pathogenesis, focusing merely on glycemic control. This study aims to explore the potential of Metabolik-CRISPR, an innovative targeted genetic engineering approach, in breaking the chain of chronic insulin resistance. The method used is a comprehensive literature review analyzing recent advancements in CRISPR-Cas9 applications, ceRNA network regulations, and nanoparticle delivery systems. The results indicate that Metabolik-CRISPR effectively intervenes in critical signaling pathways (INSR, IRS1, AKT2) and corrects ceRNA network imbalances. Furthermore, the integration of Magnetic Peptide-Imprinted Nanoparticles (MPIPs) significantly enhances the targeted delivery and activation of endogenous insulin genes safely. In conclusion, Metabolik-CRISPR offers a fundamental, permanent, and comprehensive cellular rehabilitation strategy, shifting the paradigm of T2DM management from symptom amelioration to targeted genetic restoration.

FAKTOR DOMINASI IKAN SAPU-SAPU (Pterygoplichthys sp.) SEBAGAI SPESIES INVASIF: ADAPTASI DAN BIOAKUMULASI LOGAM BERAT

Freshwater ecosystems in Indonesia are currently facing increasing environmental pressure due to anthropogenic activities, including domestic, industrial, and agricultural waste, which contribute to declining water quality and rising heavy metal contamination. These conditions have altered aquatic community structures and promoted the dominance of invasive species, particularly the suckermouth armored catfish (Pterygoplichthys sp.). This study aims to analyze the factors contributing to the dominance of Pterygoplichthys sp. in Indonesian freshwater ecosystems, examine its morphological and physiological adaptations, evaluate its capacity for heavy metal bioaccumulation, and assess the ecological impacts and implications for both the environment and human health. The study employed a qualitative descriptive method through a comprehensive literature review of relevant scientific publications. The findings indicate that Pterygoplichthys sp. possesses a high level of adaptability to extreme environmental conditions, including waters with low dissolved oxygen levels and high pollution loads. These adaptations are supported by morphological characteristics such as bony armor plates and a sucker-shaped mouth, as well as physiological traits including the use of an accessory respiratory organ and tolerance to environmental stress. Furthermore, this species is capable of accumulating various heavy metals, including lead (Pb), cadmium (Cd), mercury (Hg), and arsenic (As), indicating the occurrence of bioaccumulation resulting from exposure to contaminated environments. The combination of adaptive capacity and tolerance to heavy metals provides a competitive advantage over native species, thereby strengthening its dominance in freshwater ecosystems. The dominance of Pterygoplichthys sp. has been associated with reduced biodiversity, alterations in trophic structure, disruption of local fisheries, and potential human health risks through the consumption of contaminated fish. Therefore, the dominance of the suckermouth armored catfish is the result of interactions among adaptive capabilities, heavy metal bioaccumulation, and environmental degradation, which collectively support the success of this invasive species in colonizing Indonesian freshwater ecosystems.

This study aims to conceptually develop and evaluate the Green-Back Calendar model as an integrative framework for internalizing green behavior among Generation Z students in urban schools, with particular emphasis on supporting zero-waste school ecosystems. The Green-Back Calendar is a habit-tracking instrument designed to systematically record and reinforce daily pro-environmental actions, symbolically representing the progressive greening back of student behavioral patterns toward ecological responsibility. Employing a semi-systematic literature review methodology, this study collected and analyzed peer-reviewed articles, institutional reports, and scholarly publications sourced from Google Scholar, ERIC, Scopus, and SINTA databases, published between 2015 and 2024. Following PRISMA-informed selection criteria, 42 studies were incorporated as primary sources of conceptual synthesis, analyzed through thematic synthesis to identify recurring patterns and theoretical convergences. The findings demonstrate that the Green-Back Calendar operates through three sequentially integrated and mutually reinforcing pillars: (1) habit formation, grounded in a minimum 66-day repetition cycle, transforms conscious recycling efforts into automated default actions; (2) digital monitoring, incorporating gamification elements, provides real-time feedback and collective accountability, substantially increasing student participation; and (3) character incentives, emphasizing social recognition over punitive measures, cultivate intrinsic motivation and durable moral responsibility. The theoretical architecture draws upon the Theory of Planned Behavior, Habit Formation Theory, Social Cognitive Theory, and Self-Determination Theory, each contributing distinct explanatory mechanisms. This integrative framework offers a scalable and contextually feasible solution toward achieving Sustainable Development Goals 4 and 12, with practical implications for educational policymakers, school administrators, and local governments in designing evidence-based character education programs oriented toward long-term environmental sustainability.

Microplastic pollution in freshwater bodies has become one of the global environmental challenges affecting ecosystems and human health. Rising temperatures and UV radiation intensity due to climate change further accelerate the degradation of plastic waste, thereby increasing the accumulation of microplastics in aquatic environments. Therefore, environmentally friendly technological innovations are needed to effectively reduce microplastic pollution. CLINARY was synthesized by modifying rice bran-derived cellulose using a choline chloride–glycerol-based NADES system to enhance its adsorption affinity toward PET microplastics. The research method involved CLINARY from rice bran cellulose, followed by testing its adsorption capacity for polyethylene terephthalate (PET) microplastics in freshwater samples using UV-Vis spectrophotometric analysis. The results of the study indicate that CLINARY exhibits high microplastic adsorption capacity with an efficiency of 72.1–85.7% under optimal conditions and pH 5. The physicochemical interactions between the hydroxyl groups on NADES and the surface of the microplastic polymers enable an effective adsorption process through FTIR. Furthermore, the use of rice bran waste as an adsorbent raw material not only reduces agricultural waste but also contributes to preserving the quality of freshwater resources, which are increasingly vulnerable due to the pressures of climate change. This innovation demonstrates potential as an eco-tech solution for managing microplastic pollution in water bodies while supporting efforts to mitigate the environmental crisis through the use of renewable resources and the application of environmentally friendly technologies in water quality treatment.

Desain Konseptual ECO-CAP: Tinjauan Pustaka Sistematis Karbon Aktif Limbah Ban dan Bio-Binder Berbasis Pati untuk Superkapasitor Ramah Lingkungan

Mon, 03 Aug 2026 16:00:37 +0000

Waste tire residues constitute a persistent environmental liability owing to their cross-linked polymer architecture and biological inertness. Simultaneously, the commercialization of advanced energy storage devices is constrained by prohibitive manufacturing costs and reliance on environmentally harmful synthetic binders such as polyvinylidene fluoride (PVDF). This study proposes ECO-CAP, a conceptual supercapacitor system integrating high-purity activated carbon derived from waste tires with a cassava starch-based green bio-binder, addressing four principal research objectives. (a) Based on a systematic review of ten open-access primary sources (2021–2026), tire-derived activated carbon produced via pyrolysis at 700–800°C followed by KOH chemical activation (mass ratio 1:2 to 1:4) consistently yields electrode materials with specific surface areas (S-BET) of 100–1,200 m² g⁻¹, hierarchical micro-mesopore structures, and in-situ S/N heteroatom doping that simultaneously enhances electrical conductivity and introduces pseudocapacitive contributions. (b) Comparative analysis of biopolymer binder systems demonstrates that the abundant hydroxyl groups of cassava starch form strong hydrogen bonds with the carbon electrode surface, enabling water-processable electrode fabrication while eliminating the need for toxic N-methyl-2-pyrrolidinone (NMP) solvent, with electrochemical performance comparable to PVDF. (c) Based on a material analogy approach derived from meta-analysis of analogous material systems in the literature, ECO-CAP is projected to achieve a specific capacitance of 150–210 F g⁻¹ at 1 A g⁻¹, energy density of 18–30 Wh kg⁻¹, power density of 300–600 W kg⁻¹, and cycle retention of ≥85% after 1,000 cycles in a symmetric two-electrode cell configuration with aqueous KOH electrolyte; these projections require experimental validation through cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy characterization. (d) The fabrication cost of ECO-CAP electrodes is estimated to be 85–94% lower than that of conventional systems, and the dual valorization of waste tires alongside the elimination of hazardous chemicals from the production chain provide a compelling economic rationale for circular economy implementation aligned with SDGs 7 and 12.

ReGrow: Inovasi Pengolahan Limbah Jerami, Tulang Ikan Laut, dan Lamtoro sebagai Produk Organik Multifungsi (Pupuk, Insektisida, dan Nutrien Ternak Ruminansia) Terintegrasi Platform Digital

This study examines the underutilization of agricultural and marine organic waste in the Special Region of Yogyakarta and to formulate the initial concept of ReGrow based on a circular economy and digital platform. Data from Badan Pusat Statistik indicate that rice production in Yogyakarta reached approximately 452.83 thousand tons of dry unhusked rice in 2024, generating abundant rice straw waste, while fish-based culinary activities at Pantai Baru produce fish bone waste that remains largely underutilized. This study employed a qualitative descriptive approach using observation, semi-structured interviews, literature review, thematic analysis, and design thinking. The findings indicate that the main problem lies not only in the large volume of organic waste, but also in the absence of an integrated cross-sector value chain, the low utilization of waste, and limited access to education and market connectivity. Empirical findings show that most rice straw is still burned after harvest because it is considered to have no economic value, while fish bone waste is generally discarded without further processing. Based on these findings, this study formulates ReGrow as an initial innovation design integrating rice straw, marine fish bones, and lamtoro (Leucaena leucocephala) into the concept of multifunction organic products in the form of organic fertilizer, botanical insecticide, and ruminant livestock nutrients supported by a digital platform. The novelty of this study lies in the systemic integration of cross-sector waste, multifunction product orientation, and the support of a local circular economy-based digital ecosystem. However, this study has not conducted laboratory validation or product effectiveness testing; therefore, the findings are positioned as an initial conceptual model requiring further development and validation.
