Abstract

Climate change has intensified environmental hazards, including floods, landslides, and droughts, with Pekalongan Regency, Indonesia, emerging as a vulnerable region facing these multifaceted challenges. While flood-related studies dominate existing study, drought impacts remain understudied, despite their growing prevalence. Current climate hazard assessments in Pekalongan's adaptation plans rely heavily on historical data, limiting their predictive accuracy. This study addresses these gaps by developing a Remote Sensing Ecological Index (RSEI) model to evaluate ecological quality and its association with drought hazards, aligning with climate-resilient development objectives. The study employs Landsat imagery to construct RSEI using four key indicators: NDVI (greenness), WET (wetness), NDBSI (dryness), and LST (heat). Drought hazard data were derived from 2023 disaster records provided by Pekalongan's Regional Disaster Management Agency (BPBD). Statistical analysis using chi-square tests examined the relationship between RSEI components and drought hazard classes.Results demonstrate that RSEI's first principal component (PC1) effectively captures spatial ecological patterns, with southern regions (notably Petungkriyono's tropical rainforest) exhibiting "good" to "excellent" conditions, while northern urbanized areas score lower ("fair" to "poor"). PC1 shows a statistically significant association with drought hazard, unlike PC2 or PC3, suggesting its utility as a drought vulnerability indicator. However, the chi-square approach only identifies categorical relationships without quantifying effect strength or direction, highlighting methodological limitations. This study contributes to climate adaptation science by validating RSEI's applicability for drought assessment in tropical coastal regions. Future study should incorporate ordinal regression or spatial modeling to enhance predictive capability. The findings support evidence-based policymaking for targeted mitigation in Pekalongan Regency and similar vulnerable regions, emphasizing the integration of ecological monitoring into climate adaptation frameworks.

Abstract

Understanding the concept and hands-on skills in microbiology is crucial for science teachers because they help students develop critical thinking and retain information. This study aimed to develop a team-based project worksheet using a kitchen microbiology approach to improve students’ concept understanding and hands-on skills in identifying fungi from orange peels (Citrus spp.). The research employed a modified Borg and Gall R&D method to develop the worksheet (planning, product development, limited trials, and product revision). A limited trial was conducted to assess the students’ performance in a small-scale study involving 9 students selected from the Science Education Undergraduate Study Program at Universitas Negeri Semarang, using a one-group pretest-posttest design. The worksheet was validated, and all data were analyzed quantitatively. The results of worksheet validation by media and content experts indicated the worksheet is highly feasible (average >93%). Results showed a significant improvement in concept understanding and hands-on skills, with an N-Gain of 0.71. In conclusion, the kitchen microbiology-based worksheet effectively enhanced students’ concept understanding and hands-on skills while requiring further refinement. Its novelty lies in the use of everyday kitchen materials as educational media, the integration of teamwork and scientific communication, and the interdisciplinary blend of microbiology and sustainability, positioning it as a promising contextual learning model with both practical and social impact.

Abstract

  The home-scale batik industry in Pekalongan, while contributing to the local economy, generates wastewater containing heavy metal chromium (Cr) and organic pollutants, posing environmental risks. This study evaluated the effectiveness of phytoremediation using Eceng gondok (Eichhornia crassipes), kangkong air (Ipomoea aquatica), and their combination to reduce Cr, BOD, COD, and TSS in batik wastewater. Experiments were conducted at three wastewater concentrations (25%, 50%, 100%) over 14 days. Results showed significant reductions in all parameters: Cr removal was highest with WS at 100% concentration (93.9%), BOD and COD decreased up to 90%, and TSS decreased up to 91.1% with the WH-WS combination. pH (6.9–7.3) and temperature (27–32.8°C) remained optimal. These findings indicate that WH, WS, and their combination provide an effective and eco-friendly approach for treating batik wastewater in Pekalongan.

Abstract

The increasing demand for renewable energy necessitates sustainable alternatives such as biochar briquettes derived from agricultural waste. This study aims to optimize the production process and evaluate the physical, mechanical, and combustion properties of biochar briquettes made from corn residues, rice husks, and coconut shells. The methodology includes biomass carbonization, binder ratio optimization, and systematic testing of key quality parameters such as moisture content, density, ash content, and calorific value. Results indicate that an optimal biomass-to-binder ratio yields a high calorific value (7,192 kcal/kg) and low ash content (3.57%), enhancing combustion efficiency. Maintaining moisture content below 10% enhances ignition and prolongs burning time. These findings highlight biochar briquettes' role in carbon sequestration, biomass conversion, and sustainable waste management, supporting the circular economy and reducing environmental pollution. Biochar briquettes offer a clean, accessible energy solution, contributing to global energy security and climate change mitigation.

Abstract

Climate change has emerged as a global crisis with severe consequences for tropical and coastal regions. Pekalongan Regency, Indonesia, exemplifies these challenges, facing recurrent floods and landslides that threaten livelihoods and infrastructure. Risk mapping is urgently needed to guide adaptation strategies, yet many regions face constraints due to limited data availability. This study develops a multi-hazard risk mapping approach that integrates Geographic Information System (GIS) technology with stakeholder participation through Public Participation GIS (PPGIS). Hazard and vulnerability analyses were conducted using disaster records, socio-economic indicators, and spatial datasets, validated through Focus Group Discussions (FGDs) with government agencies and local stakeholders. The findings were synthesized into a structured four-stage framework encompassing stakeholder education (Kick-off), preliminary spatial analysis, participatory indicator validation, and finalization of risk maps. Results reveal distinct spatial patterns: flood risks dominate northern coastal and riverine villages, while landslide hazards are concentrated in the southern highlands. Stakeholder involvement not only improved data validity but also enhanced local adaptive capacity. The proposed PPGIS framework provides a transferable model for participatory climate resilience planning, particularly in data-scarce regions such as the global south area.

Abstract

Science education can be enriched by integrating local culture and wisdom, particularly through the exploration of mangrove ecosystems. Mangroves not only play an essential ecological role but also embody local knowledge that can be linked to scientific concepts. This study aims to identify and describe the local wisdom of the Nipah Panjang, Kubu Raya Regency, West Kalimantan community in utilizing various mangrove species as a source of contextual science learning. A descriptive qualitative design with an ethnopedagogical approach was employed, combining literature review, document analysis, and brief field observations. The findings reveal that six dominant mangrove species, Avicennia alba, Avicennia marina, Bruguiera gymnorrhiza, Excoecaria agallocha, Rhizophora apiculata, and Rhizophora mucronata, are utilized in diverse ways according to their biological traits and bioactive compounds. Their uses include construction materials, firewood, charcoal, traditional medicine (e.g., for eye treatment, anti-inflammatory purposes, and gastric remedies), and support for honeybee cultivation. Such practices highlight the integration of ethnoscientific knowledge with science concepts, including ecosystem adaptation, plant structure, wood properties, and bioactive compounds. By bridging modern science with local wisdom, science education can become more contextual and meaningful, while fostering environmental awareness and a conservation-oriented mindset toward coastal ecosystems.

Abstract

Sudachi citrus is a valuable commodity with the potential to support local and global food security. However, post-harvest handling challenges often hinder its quality and yield.  This community engagement program aimed to optimize Sudachi harvesting practices in Oi-Cho, Anan City, Tokushima Prefecture, Japan, by implementing Good Handling Practices (GHP). In collaboration with international NGOs, i.e., Dejavato Foundation and NICE Japan, the program involved international work campers and residents in adopting effective GHP methods focused on improving harvesting, storage, and distribution techniques. The initiative improved harvesting technique and hygiene compliance among participants, and introduced a product diversification strategy to reduce post-harvest waste from lower-grade fruit, aligning directly with Sustainable Development Goal (SDG) 2, which seeks to end hunger and promote sustainable agriculture. Furthermore, the program exemplifies SDG 17 by fostering inclusive, cross-border partnerships that leverage community-based innovation and knowledge exchange. Ultimately, this program achieved a strategic step toward sustainable Sudachi production and harvesting, as well as strengthens international collaboration through participatory, grassroots engagement.

Abstract

Banjir rob di wilayah pesisir utara Jawa Tengah, khususnya pada koridor Semarang-Demak, berdampak signifikan pada kinerja transportasi darat serta meningkatkan emisi karbon. Penelitian ini bertujuan untuk menganalisis emisi karbon dioksida (CO₂) dari aktivitas transportasi akibat banjir rob serta mengkaji potensi penyerapan karbon oleh ekosistem mangrove di wilayah pesisir Semarang-Demak. Pendekatan kuantitatif digunakan melalui perhitungan emisi IPCC Tier-2, analisis volume lalu lintas, serta pemetaan tutupan mangrove berbasis citra Sentinel-2 dan indeks NDVI.Hasil analisis menunjukkan bahwa volume lalu lintas pada ruas Sayung–Kaligawe mencapai ±47.788 kendaraan per kejadian rob dengan durasi kemacetan 4–8 jam, yang menghasilkan tambahan emisi sekitar 286,7–573,5 ton CO₂ per kejadian dan berpotensi melebihi 300.000 ton CO₂ per tahun. Di sisi lain, ekosistem mangrove memiliki kapasitas penyerapan karbon yang tinggi, yaitu sekitar 367–734 ton CO₂/ha/tahun, dengan simpanan karbon total >700 ton C/ha. Tutupan mangrove di Kota Semarang (111,06 ha) dan Kabupaten Demak (±1.781,18 ha) berperan penting sebagai penyerap karbon pesisir, namun emisi transportasi akibat rob yang berulang berpotensi mengimbangi kemampuan serapan tersebut. Temuan ini menegaskan perlunya integrasi pengendalian rob, pengurangan emisi transportasi, dan konservasi mangrove untuk mitigasi perubahan iklim di pesisir.
