Abstract

Brown planthopper (Nilaparvata lugens) remains one of the most destructive rice pests, necessitating environmentally friendly management supported by effective agricultural extension. This study examined the effects of farmer characteristics and Articulate Storyline-based interactive digital extension on strengthening this capacity for sustainable pest management in Tulungagung Regency, Indonesia. A one-group pretest–posttest pre-experimental design involved 84 rice farmers selected through multistage sampling. Questionnaires were validated (63 of 67 items valid, r-table = 0.361, n = 30) and reliable (Cronbach’s alpha 0.851–0.905). Intervention effectiveness was evaluated using N-Gain analysis, while multiple linear regression with classical assumption testing identified the influencing factors. Farmer characteristics significantly affected the outcome (B = 0.141, standardized ? = 0.150, t = 2.301, p = 0.024), while the digital extension medium showed a substantially greater influence (B = 1.249, standardized ? = 0.866, t = 13.310, p < 0.001). The model explained 69.1% of the variance (adjusted R² = 0.683; F (2,81) = 90.588, p < 0.001), confirming that instructional design outweighs demographic factors in building this capacity for effective pest control. Extension agencies should therefore prioritize content clarity and instructional quality over demographic targeting when developing digital media. As a single-group, one-region study, causal inference and generalizability remain limited; quasi-experimental or multi-region designs are recommended for future research. Overall, the findings highlight Articulate Storyline’s potential as an innovative tool for advancing environmentally friendly brown planthopper control and the broader digital transformation of agricultural extension services.

Abstract

Puli crackers are still reported to contain borax as an unauthorized food additive, posing potential risks to food quality and safety. This study aimed to determine the borax content, total mold count, physicochemical properties (moisture content, expansion volume, and breaking force), and sensory characteristics of branded packaged puli crackers marketed in Surabaya, Indonesia. A descriptive study with a cross-sectional design was conducted using laboratory analyses. A total of 20 branded packaged puli cracker samples were collected from cracker retail stores using a total sampling technique.The results showed that 100% of the samples tested positive for borax, with concentrations ranging from 20.14 to 113.87 ppm. The moisture content ranged from 9.01% to 13.62%. All samples complied with the Indonesian National Standard (SNI 01-4307-1996) for total mold count, with values ranging from <10 to 7.0 × 10² CFU/g. The expansion volume ranged from 148.78% to 1041.08%, while the breaking force ranged from 2.54 to 13.61 N. The microbiological quality of the samples met the national standard for mold contamination; however, borax was detected in all samples, indicating the continued illegal use of borax in branded packaged puli crackers marketed in Surabaya.

Abstract

Limited renewable energy literacy and community participation remain significant challenges to the sustainable adoption of solar energy technologies in rural areas. Although portable solar panel systems offer a practical solution for improving sustainable energy access, their long-term utilization is often constrained by insufficient community knowledge and technical capacity. This study evaluated the implementation of a portable solar panel system through a participatory community empowerment program in Jatirejo Village, Semarang Regency, Indonesia. A community service–based approach integrated educational sessions, hands-on training, practical demonstrations, and technology transfer to enhance participants' understanding and engagement in renewable energy utilization. Data were collected from 20 community members using structured pre- and post-program questionnaires, direct observations, and activity documentation and were analyzed descriptively. The proportion of participants who understood the basic functions of portable solar panel systems increased from 30% to 85%, while familiarity with system operation improved from 15% to 75%. Interest in renewable energy increased from 45% to 90%, and active participation during program activities increased from 25% to 80%. These findings indicate that the participatory approach strengthened local capacity and enhanced community acceptance of renewable energy technology. Integrating portable solar panel deployment with community empowerment activities provides an effective strategy for improving renewable energy literacy, promoting sustainable technology adoption, and strengthening community participation. The findings offer practical implications for community service initiatives, educational institutions, and local governments seeking to expand sustainable energy access and support the achievement of Sustainable Development Goal (SDG) 7 through participatory renewable energy programs.

Abstract

To mitigate seasonal flooding in the Keser River watershed, Trenggalek Regency, East Java, this study estimated design rainfall and flood discharges using the HEC-HMS hydrological model based on rainfall records from 2014–2024. Areal rainfall was calculated using the Thiessen Polygon method, while frequency analysis identified the Log Pearson Type III distribution as the most appropriate probability model according to the Chi-Square and Kolmogorov–Smirnov goodness-of-fit tests. The 43.06 km² watershed was delineated into seven sub-watersheds using DEM and land-use data. Rainfall losses and runoff transformation were simulated using the SCS Curve Number (SCS-CN) and SCS Unit Hydrograph methods, respectively. The simulated peak discharges at the watershed outlet were 512.9, 678.5, 772.3, 877.8, 947.9, and 1,011.7 m³/s for the 2-, 5-, 10-, 25-, 50-, and 100-year return periods, respectively. The simulated hydrographs exhibited a steep rising limb followed by a gradual recession limb, indicating rapid runoff generation and delayed flow attenuation. These results demonstrate that the HEC-HMS model effectively represents the hydrological behavior of the Keser River watershed and provides reliable design flood estimates to support flood mitigation planning and sustainable water resources management.

Abstract

The tofu industry generates wastewater containing high concentrations of total dissolved solids (TDS) and total solids (TS), posing significant environmental concerns. This study aimed to develop a chitosan-modified durian seed (Durio zibethinus) composite bioadsorbent for the removal of TS and TDS from tofu wastewater. The composite was characterized using scanning electron microscopy (SEM), X-ray fluorescence (XRF), and particle size analysis (PSA), followed by batch adsorption experiments at different adsorbent dosages. The initial wastewater contained 7,528 mg/L TDS and 9,139 mg/L TS. The composite exhibited superior adsorption performance compared with pristine chitosan, achieving a maximum TDS removal efficiency of 65.84%, reducing the TDS concentration to 2,572 mg/L, while TS removal reached 47.70%, with the final TS concentration decreasing to 4,780 mg/L at an adsorbent dosage of 1 g. Material characterization demonstrated that chitosan modification improved the composite morphology and physicochemical properties, thereby enhancing its adsorption performance. These findings indicate that the chitosan-modified durian seed composite is an effective, low-cost, and environmentally friendly bioadsorbent for tofu wastewater treatment. Furthermore, the utilization of durian seed waste as a bioadsorbent contributes to agricultural waste valorization and supports circular economy practices.

Abstract

Generator set failures are commonly investigated by examining individual damaged components; however, limited studies have systematically integrated failure mechanism analysis, failure propagation analysis, and Root Cause Identification (RCI) to explain the sequence of events leading to total system breakdown. This study aims to identify the failure mechanisms and root causes of a total breakdown in a Firman FPG1500ECII gasoline-powered generator set and to develop evidence-based preventive maintenance recommendations. The investigation employed a forensic engineering approach by integrating systematic visual inspection, tribological failure analysis, failure propagation analysis, Fishbone Diagram, and 5 Why Analysis. The results revealed that inadequate lubrication management was the primary initiating factor, leading to progressive piston ring wear, bearing damage, carbon deposit accumulation, valve leakage, ignition system deterioration, and ultimately complete engine failure. Failure propagation analysis demonstrated that the breakdown resulted from the interaction of multiple component failures rather than the failure of a single component. Based on the identified root causes, an evidence-based preventive maintenance schedule was developed using manufacturer recommendations and previous maintenance studies. The principal contribution of this study is the development of an integrated engineering failure analysis framework that systematically links failure mechanisms, failure propagation, and Root Cause Identification to support maintenance decision-making and improve the reliability of gasoline-powered generator sets operating under similar conditions.

Abstract

The rapid growth of online travel agencies (OTAs) has intensified competition, requiring companies to understand the factors influencing consumers' purchase and repurchase decisions. This study aims to examine the effects of TikTok content marketing, perceived value, and trust on purchase decisions and repurchase decisions among online travel consumers in Surabaya. A quantitative approach was employed using a structured questionnaire distributed to 120 respondents selected through purposive sampling. The data were analyzed using Covariance-Based Structural Equation Modeling (CB-SEM) with AMOS. The results indicate that TikTok content marketing, perceived value, and trust have positive and significant effects on purchase decisions. Regarding repurchase decisions, perceived value has a positive and significant effect, whereas TikTok content marketing and trust do not have significant effects. In addition, purchase decisions significantly and positively influence repurchase decisions, confirming their important role in encouraging repeat purchases. Among the examined variables, perceived value is the strongest determinant of repurchase decisions. These findings suggest that online travel service providers should prioritize delivering superior value while maintaining effective TikTok marketing strategies and consumer trust to strengthen purchase and repurchase decisions.

Abstract

The high incidence of diarrhea in Rungkut District, Surabaya, which reached 3,341 cases, highlights critical concerns regarding the safety of beverages sold at container-based outlets. This study aimed to evaluate the food safety of iced tea beverages sold by container-based vendors in Rungkut District by analyzing the presence of artificial sweeteners (saccharin and cyclamate), assessing microbiological contamination (TPC, Coliform bacteria, and Escherichia coli), and examining their relationship with vendors' hygiene and sanitation practices. A descriptive survey with a cross-sectional approach was conducted, involving interviews, observation, and laboratory analysis for 20 container-based tea vendors selected through purposive sampling. Data were statistically analyzed using Fisher's exact tests at a 95% confidence level (p<0,05). Laboratory results showed that 100% of the tea samples were negative for saccharin and cyclamate. However, microbiological evaluation revealed that 85% of the samples failed to meet the national safety standard (PerBPOM No. 13 Year 2019) with critically high TPC values ranging from 47×103 to 134×105 CFU/mL. Furthermore, 80% of the samples exceeded the Coliform safety limit (<1.8 MPN/mL), although 100% of the samples were negative for Escherichia coli. Statistical analysis confirmed there was no significant relationship (p>0.05) between hygiene sanitation factors (personal hygiene, equipment sanitation, serving sanitation, and environmental sanitation) and the microbiological contamination levels, suggesting external risk factors such as raw water or contaminated ice blocks as the primary sources of contamination.

Abstract

The misuse of formalin and high levels of microbial contamination in tofu are still commonly found today, partly due to poor hygiene and sanitation practices among vendors. This study aims to identify the misuse of formalin, levels of bacterial contamination, and Escherichia coli contamination resulting from the hygiene and sanitation conditions of tofu vendors at the Traditional Market in the East Branch of PD Pasar Surya, Surabaya. This study employed an exploratory and descriptive survey method using a cross-sectional approach, involving observations and interviews with 23 white tofu vendors at the Traditional Market in the East Branch of PD Pasar Surya, Surabaya. The analyses conducted included qualitative formalin testing, Total Plate Count (TPC) testing, and Escherichia coli contamination testing using the Most Probable Number (MPN) method. The relationship between vendors’ sanitation conditions and levels of bacterial contamination and E. coli contamination was assessed using a chi-square test at a 5% significance level. Laboratory results revealed that 100% of all samples (23 out of 23 samples) tested negative for formalin. Approximately 8.69% (2 out of 23 samples) exhibited TPC values exceeding the SNI 01-3142-1998 quality standards (ranging from 1,0 x 10? to 1,2 x 10? colonies/g). Furthermore, 39% (9 out of 23 samples) tested positive for Escherichia coli contamination (ranging from 3.6 to 28 MPN/g). A significant correlation (p<0,05) was found between hygiene-sanitation and TPC, whereas no significant correlation (p>0,05) was observed for Escherichia coli contamination in white tofu sold in the Traditional Markets of the Eastern Branch Region of PD Pasar Surya Surabaya.

Abstract

This study investigates the synthesis of Green Calcium Ammonium Phosphate (CAP) fertilizer utilizing red mussel shells (Anadara granosa) as a biogenic precursor. Response Surface Methodology (RSM) was employed to optimize process variables, identifying an optimal operating window at pH 8.000 and a feed-to-phosphoric acid ratio of 0.100 (w/v). Under these conditions, the model predicted a Phosphorus concentration of 25.647%, Calcium content of 71.861%, and a Yield of 77.621 (desirability: 0.628). However, ANOVA diagnostics revealed a significant Lack of Fit, suggesting that standard quadratic models are sensitive to latent physicochemical parameters inherent in the biogenic matrix. These statistical discrepancies indicate that while successful at the laboratory scale, current predictive frameworks require kinetic refinement prior to large-scale industrial implementation.
