Stunting is a condition of linear growth disorders due to chronic lack of intake and occurs in many developing countries including Indonesia. Stunting is a problem because it is associated with an increased risk of illness and death, suboptimal brain development so that motor development is delayed and mental growth is inhibited, this can hinder the Indonesian government's program towards a superior and quality golden generation in 2045. The purpose of this study was to determine the risk factors for household environmental sanitation on the incidence of stunting in toddlers in Dongos Village, Kedung I Health Center, Jepara Regency. This study is an observational analytical study using a quantitative method with a case-control study design, namely a study comparing case and control groups and then retrospectively examining risk factors that might explain the incidence of stunting. The study sample was stunted and non-stunted toddlers, calculated using lemmeshow formula with the absolute accuracy proportion estimate with a total sample of 100 respondents divided into 50 case groups and 50 control groups. Data analysis with Chi Square test then further using logistic regression test using prediction modeling. The results of the study showed that unsafe household waste management has a risk factor of 3.6 times greater for stunting in toddlers (p-value 0.029; Odds Ratio = 3.632; 95% CI = 1.082- 12.183). Houses with unsafe household waste management have a 5.2 times greater risk of experiencing stunting in toddlers (p-value 0.025; Odds Ratio = 5.268; 95% CI = 1.077- 25.779). Household toilet ownership (p value = 0.400) and household drinking water consumption patterns (p value = 0.338) were not proven to be risk factors for stunting in toddlers in Dongos Village, Kedung I Health Center working area, Jepara Regency.

True shallot seed (TSS) is one of the alternative potential technologies to solve the availability of seed quality on shallot in Indonesia. Another problem in shallot production is infection by purple blotch and twisted disease. This research evaluated the potency of Rhizophagus intraradices and Trichoderma asperellum as bioprotectants and biofertilizer. T. asperellum was mixed in the soil before seedling transplanting, and R. intraradices was applied around the seedling roots at transplanting. The observed parameters were the shallot growth (the plant height, number of leaves, and length of root), plant health (disease incidence and intensity), and bulb resistance to Fusarium solani. The result showed that R. intraradices and T. asperellum increased the resistance of onion bulbs to the pathogen F. solani in the postharvest period, indicated by R. intraradices treatment that had an infection area of 21.99 mm2, followed by T. asperellum treatment 26.63 mm2, and control of 37.66 mm2. Keywords: Rhizophagus intraradices, Trichoderma asperellum, true shallot seed

The Troso weaving industry in Jepara, Indonesia, is a traditional craft sector that relies on synthetic dyes and manual production, thereby exposing workers to chromium (Cr) and particulate matter (PM2.5 and PM10) with potential respiratory and neurological risks. This study aimed to analyze their association with respiratory and neurological disorders among workers. A cross-sectional design was applied involving 101 weaving workers from four production sites. Environmental sampling measured Cr concentrations in wastewater and PM2.5/PM10 in the ambient air, while worker characteristics and health complaints were assessed using the ECSC-87 and Q18 questionnaire. Data were analyzed using chi-square tests and odds ratios. Cr concentrations in wastewater ranged from <0.010 to 0.104 mg/L, remaining below the effluent quality standard of 1.0 mg/L but confirming the continuous use of chromium-based dyes discharged without treatment. Average PM2.5 and PM10 levels were 108.75 µg/m³ and 117.75 µg/m³, both exceeding national air quality standards (55 and 75 µg/m³). Bivariate analysis showed that respiratory disorders were significantly associated with exposure duration ≥40 hours/week (OR=7.333; p=0.0001) and working period >5 years (OR=20.935; p=0.0001), whereas dye type, dyeing frequency, and PPE use were not significant. Neurological disorders were significantly associated with exposure duration (p=0.001), working period (p=0.001), type of dye (p=0.0001), frequency of dyeing (p=0.018), and PPE use (p=0.0001). Environmental monitoring confirmed elevated PM levels and chromium-based dye use, while statistical analysis showed that prolonged exposure and long working periods associated with respiratory disorders, and neurological disorders were linked to multiple occupational factors.

Introduction: The rising global production of municipal solid waste (MSW) poses significant ecological challenges. In developing countries, inadequate landfill management results in the uncontrolled release of hazardous gases and leachate, posing significant risks to human health. This systematic review investigated the association between environmental factors at these landfills and adverse human health outcomes. Methods: This review was conducted in accordance with the PRISMA guidelines. A comprehensive search was rapidly conducted across ScienceDirect, Scopus, PubMed, and EBSCOhost for articles published between 2020 and 2025. PECO criteria screening was conducted independently by two reviewers, resulting in the selection of 25 articles for critical synthesis. Results: Hazardous landfill pollutants—including heavy metals, volatile organic compounds (VOCs), and particulate matter—are rapidly escalating severe health issues. Residents and landfill workers face acute respiratory and cardiovascular disorders, heightened cancer risk, reproductive issues, and neurological impairments. Leachate contamination of soil and groundwater compounds these urgent systemic risks. Conclusion:The ongoing failure to manage landfills effectively, particularly in developing countries, has triggered a pressing environmental and public health crisis. Immediate action to improve waste management and enforce stricter environmental policies is critical for preventing further harm.
