Abstract

The promise of educational technology (EdTech) to democratize learning in Indonesia is consistently undermined by a profound digital divide, particularly in remote and archipelagic regions where internet connectivity is poor and infrastructure is limited. This study explores the application of frugal innovation principles as a direct and context-aware strategy to address this challenge. A multi-phase, mixed-methods Design-Based Research (DBR) methodology was employed over 18 months. The study involved the collaborative design, development, and implementation of "Lentera," a low-bandwidth, asynchronous, and offline-first learning system, in six remote primary schools in the Maluku Islands. A quasi-experimental design compared three intervention schools with three control schools over one academic year. Data collection was extensive, including pre- and post-intervention literacy and numeracy assessments, System Usability Scale (SUS) surveys, system usage logs, semi-structured interviews with 18 teachers, and over 80 hours of classroom observation. Data were analyzed using a two-level Hierarchical Linear Model (HLM) to account for the clustered nature of students within schools. The Lentera system demonstrated high feasibility and positive user adoption, with offline peer-to-peer sharing proving to be a critical feature for content distribution. Quantitative analysis revealed a statistically significant and substantial improvement in learning outcomes for the intervention group in both literacy (γ = 11.85, p < 0.001) and numeracy (γ = 12.91, p < 0.001) compared to the control group, after controlling for pre-test scores. The mean System Usability Scale (SUS) score was 78.5, indicating well-above-average usability. Qualitative findings, drawn from a wide range of teacher interviews and classroom observations, highlighted the system's effectiveness in supporting student-centered, differentiated instruction and fostering teacher collaboration, aligning with the core principles of Indonesia's Kurikulum Merdeka. The study provides compelling evidence that frugal innovation, embodied in a context-aware learning system, presents a viable, effective, and scalable pathway to enhancing educational quality and equity in resource-constrained environments.

Abstract

The global challenges of food insecurity (SDG 2) and water scarcity (SDG 6) require proven, sustainable governance models. Socio-ecological systems (SES) rooted in local wisdom (kearifan lokal) offer resilient alternatives. The Balinese Subak, a UNESCO World Heritage site guided by the Tri Hita Karana philosophy, is a pre-eminent example. This research employed a 10-year (2015-2025) longitudinal, mixed-methods, comparative case study of two Subak systems in Bali. We collected a comprehensive dataset including 1,200 systematic water sampling events (yielding 7,200 analytical data points for pH, TSS, BOD, COD, NO3-N, PO4-P) and a 10-year rolling panel survey (n=2,000 completed survey-years) to assess agricultural and governance metrics. Qualitative data (n=60 interviews, n=24 meeting observations) were thematically analyzed. Generalized Linear Mixed-Effects Models (GLMMs) revealed a statistically significant time-dependent reduction in pollution, including Nitrate (β = -0.21 mg/L/year, p < .001) and BOD (β = -0.15 mg/L/year, p < .001), across both sites. This trend was strongly associated with a validated Social Governance Index (SGI). Critically, rice yields remained stable at a high-productivity average (6.2 t/ha), while chemical pesticide use declined by 48% (p < .001). Qualitative analysis identified the core mechanisms: (1) Tri Hita Karana as an internalized moral framework, (2) ritual calendars as coordination mechanisms, and (3) awig-awig as an adaptive governance system. In conclusion, the Subak system demonstrates a proven, sophisticated, and data-driven framework that operationalizes kearifan lokal to achieve the non-trade-off, simultaneous goals of sustainable agriculture (SDG 2) and clean water (SDG 6). These findings provide robust evidence that such systems are not relics but essential, adaptive governance models for global sustainability.

Abstract

Gray mold, caused by the necrotrophic fungus Botrytis cinerea, is a devastating disease in tomato production worldwide, necessitating the development of sustainable and effective control strategies. Plant-derived biostimulants offer a promising eco-friendly alternative to synthetic fungicides by enhancing the plant's innate immune system. This study, conducted in greenhouse facilities in Palembang, Indonesia, evaluated the efficacy of a novel plant-derived biostimulant (PDB-MX7), a composition of Ascophyllum nodosum and Moringa oleifera extracts, in controlling gray mold in tomato (Solanum lycopersicum L. cv. 'Mutiara'). Tomato plants were treated with PDB-MX7 and subsequently inoculated with a virulent B. cinerea isolate. We assessed disease progression, plant growth parameters, and a suite of underlying defense mechanisms. These included the quantification of oxidative stress markers (H₂O₂, MDA), the activity of key defense-related enzymes (PAL, PPO, SOD, CAT), the accumulation of defense phytohormones (salicylic acid, jasmonic acid), and the expression levels of pathogenesis-related genes (PR-1, PDF1.2) via RT-qPCR. Pre-treatment with PDB-MX7 significantly reduced gray mold disease severity by 76.4% and lesion diameter by 71.8% compared to untreated, inoculated plants. This protective effect was associated with a significant priming of the plant's defense system. PDB-MX7-treated plants exhibited lower levels of H₂O₂ and MDA upon infection, indicating reduced oxidative stress. Furthermore, these plants showed a rapid and potent induction of PAL and PPO activity (3.1-fold and 2.8-fold higher than controls at 48 hpi, respectively). This was corroborated by a significant accumulation of salicylic acid and a more than 5-fold upregulation in the expression of the SA-responsive gene PR-1, indicating the activation of Systemic Acquired Resistance (SAR). In conclusion, the novel biostimulant composition PDB-MX7 confers substantial resistance against B. cinerea in tomato by priming the plant's innate immunity, primarily through the activation of the SA-mediated SAR pathway. This study highlights the potential of PDB-MX7 as a powerful tool for integrated pest management programs in sustainable tomato cultivation.
