Abstract

Construction activities can temporarily degrade ambient air quality through fuel-combustion emissions and fugitive dust. This study assessed baseline conditions and predicted pollutant dispersion during a residential development in Jimbaran, Bali. Ambient sampling was conducted at a roadside/front-boundary point and the central project site on 22–23 May 2026 for SO?, NO?, CO, O?, non-methane hydrocarbons, TSP, Pb, PM??, and PM?.?. Construction-related increments of SO?, NO?, CO, TSP, PM??, and PM?.? were evaluated using emission-factor calculations and a Gaussian line-source screening model under atmospheric stability class B, a 1.5 m/s wind speed, and a 1.5 m receptor height. All baseline parameters complied with Indonesian ambient air standards, and the initial air quality index was classified as good. At a representative 100 m receptor, both material/equipment mobilization and building-construction scenarios remained below the standards. However, a conservative 10 m mobilization scenario increased NO? to 224.50 µg/m³ and TSP to 484.05 µg/m³ at the roadside point, exceeding the respective standards of 200 and 230 µg/m³. Modelled increments declined sharply with distance, indicating that the principal risk is localised around project access and material-handling routes. The findings support prioritizing covered loads, road wetting, speed control, immediate removal of spilled material, equipment maintenance, and targeted monitoring of NO2, TSP, PM??, and PM?.? at near-source receptors.

Abstract

The growing demand for energy and the depletion of fossil fuel reserves have accelerated the development of renewable energy sources. Biodiesel has emerged as a promising alternative because it can be produced from renewable feedstocks while reducing environmental impacts. This study investigated the effects of the composition of the crude palm oil (CPO) and waste cooking oil (WCO) blend, as well as stirring speed, on biodiesel yield and fuel properties during alkaline transesterification using a potassium hydroxide (KOH) catalyst. Five feedstock compositions consisting of 100:0, 75:25, 50:50, 25:75, and 0:100 (CPO:WCO) were evaluated at stirring speeds of 400 and 600 rpm. The transesterification process was carried out at 60°C for 60 min using a methanol to oil molar ratio of 6:1 and 1 wt.% KOH catalyst. Biodiesel products were characterized based on yield, density, kinematic viscosity, acid value, calorific value, cetane number, and fatty acid methyl ester (FAME) composition using gas chromatography mass spectrometry (GC-MS). The results demonstrated that both feedstock composition and stirring speed significantly affected biodiesel production. Increasing the proportion of waste cooking oil improved biodiesel yield, while increasing stirring speed enhanced mass transfer between methanol and oil, leading to higher conversion efficiency. The highest biodiesel yield of 80% was obtained at a CPO:WCO ratio of 25:75 with a stirring speed of 600 rpm. The produced biodiesel exhibited density, viscosity, acid value, calorific value, and cetane number within the requirements of the Indonesian National Standard (SNI 7182:2015). GC-MS analysis confirmed a FAME content of 79.18%, indicating effective transesterification. These findings demonstrate that optimizing feedstock composition and mixing intensity can improve biodiesel production efficiency while promoting the utilization of waste cooking oil as a sustainable renewable energy resource.

Abstract

Trucuk and Bojonegoro Districts in Bojonegoro Regency, East Java, are low-lying areas that experience recurring inundation whenever the Bengawan Solo River overflows during the rainy season. This study maps flood-prone zones across the two districts using a Geographic Information System (GIS) so that flood risk reduction efforts can be directed more precisely. Four physical parameters known to influence flood occurrence, annual rainfall, slope gradient, soil type, and land use, were each reclassified and assigned a score and weight reflecting their relative contribution to flooding. The four parameter maps were combined through an Intersect overlay in ArcGIS Pro, and the resulting composite scores were divided into five hazard classes using the equal-interval method. The analysis shows that the low hazard class dominates the study area with 2,873 ha (43%), followed by the very high class at 1,557 ha (23%), the high class at 1,141 ha (17%), the very low class at 1,053 ha (16%), and the moderate class at only 81 ha (1%). Slope emerged as the most influential parameter: because flat terrain (0–8%) covers 99% of the study area, this class produced the highest rating value of 27 in the overlay calculation. Interviews conducted in ten villages confirmed that the mapped hazard classes correspond with residents’ actual flooding experience, particularly among settlements located within one kilometre of the Bengawan Solo River. The resulting map is intended to help the Bojonegoro Regional Disaster Management Agency (BPBD) prioritize flood mitigation measures.

Abstract

The increasing demand for sustainable protein sources and the accumulation of organic waste have encouraged the development of insect-mediated bioconversion for resource recovery. This study evaluated the nutritional quality of Tenebrio molitor larvae reared on various organic waste substrates and assessed their suitability as an alternative feed ingredient in accordance with the Indonesian National Standards (SNI). A laboratory-scale factorial experiment was conducted using three substrate treatments: household food waste (S1), a 1:1 mixture of household food waste and seafood waste (S2), and seafood waste (S3), combined with two larval densities (0.5 and 1 larva cm?²). Harvested larvae were analyzed for crude protein, crude fat, moisture, ash, and carbohydrate contents, and data were evaluated using two-way ANOVA. Substrate composition, larval density, and their interaction significantly affected all proximate parameters (p < 0.001). The highest crude protein content (37.16%) was obtained from larvae reared on seafood waste at 1 larva cm?² (S3-D1), while carbohydrate content decreased with increasing seafood waste proportions. Crude fat ranged from 24.80–27.14%, moisture from 10.10–12.25%, and ash from 9.60–10.73%. The larvae met SNI requirements for protein and moisture in broiler, layer, and tilapia feeds. These findings demonstrate that T. molitor effectively converts organic waste into protein-rich biomass, supporting its application as a sustainable feed ingredient and promoting circular resource management.

Abstract

Flooding is one of the most frequent hydrometeorological disasters in Indonesia and continues to threaten urban areas due to rapid land-use changes, increasing impervious surfaces, and inadequate drainage systems. Malang City, East Java, has experienced rapid urban development that increases flood susceptibility in several districts. Therefore, identifying flood-prone areas and determining appropriate evacuation routes are essential components of disaster risk reduction.This study aims to identify flood-prone areas and determine optimal flood evacuation routes in Malang City using Geographic Information Systems (GIS). The analysis integrates several physical parameters affecting flood susceptibility, including rainfall, land use, slope, soil type, and topographic conditions. Spatial analysis was conducted through thematic map overlay techniques to produce flood susceptibility zoning. Furthermore, road network analysis was employed to identify the shortest and safest evacuation routes from flood-prone locations to designated evacuation points.The results are expected to provide flood hazard maps classified into several susceptibility levels and evacuation route maps that support emergency response planning. These outputs can serve as references for local governments in improving flood mitigation strategies, spatial planning, and disaster preparedness. The application of GIS demonstrates its capability to integrate spatial datasets for hazard assessment and evacuation planning, providing an effective decision-support system for sustainable urban disaster management.

Abstract

Residential water ponding has become a recurring problem in Lamongan District, Indonesia, disrupting residential activities and increasing flood risk. Accurate spatial identification of vulnerable areas is essential to support effective urban planning and drainage management. This study aims to map residential water ponding vulnerability using a Geographic Information System (GIS) and the Weighted Overlay Analysis. Five parameters, namely rainfall, slope, soil type, land use, and drainage conditions, were processed using ArcGIS through scoring, weighting, and spatial overlay techniques. A field questionnaire survey was also conducted to validate the spatial analysis results. The analysis classified the study area into four vulnerability levels: Low, Moderate, High, and Very High. The High vulnerability class dominated the study area, covering 37.14%, followed by Moderate (32.90%), Very High (25.41%), and Low (3.64%). Questionnaire results confirmed that water ponding frequently occurs in several residential areas, with respondents identifying high rainfall, inadequate drainage capacity, and blocked drainage channels as the primary contributing factors. The consistency between GIS analysis and field observations indicates that the proposed approach provides reliable spatial information for identifying priority areas for flood mitigation. The resulting vulnerability map can support evidence-based urban planning and sustainable drainage management in Lamongan District.

Abstract

Seasoned tempeh chips are a specialty product of Gresik Regency, with variations in spice formulations and raw materials among micro, small, and medium-sized enterprises (MSMEs) resulting in distinct sensory profiles. This study aimed to describe the sensory profiles of seasoned tempeh chips produced by MSMEs in Gresik Regency using the Rate-All-That-Apply (RATA) method and to determine the most preferred sample through a hedonic test. Significant differences were found in the attributes of yellow, brown, and golden-brown color, spicy aroma, crisp texture, spicy and sweet taste, lingering spiciness, and lingering sweetness. Samples 143 and 264 were characterized by spicy aroma and yellow color; sample 352 by spicy and oily sensations; sample 721 by crisp texture, brown color, and savory-salty taste; and sample 958 by fried, nutty, crisp, golden-brown, and sweet characteristics. Principal Component Analysis (PCA) explained 63.48% of the total sensory variability. Preference mapping indicated that sample 143 had the highest consumer preference (80–100%) and was primarily associated with savory and spicy aroma attributes, suggesting that these characteristics contributed most strongly to overall consumer liking.

Abstract

Horizontal Bandsaw KW15-52 by quantifying changes in vibration and metal cutting time. A quantitative one-group before-and-after experimental design was applied under controlled machining conditions. Thirty paired measurements were obtained for vibration, while 30 cutting trials were conducted for each workpiece material, ST41 steel and Aluminum 6061, before and after reconditioning. The measured outcomes were vibration acceleration (m/s2) and cutting time (s). Reconditioning included inspection, repair or replacement of defective components, reassembly, adjustment, and functional testing. Paired differences were assessed using the Shapiro-Wilk test and paired-samples t-test, with Cohen's dz used to quantify effect size. Vibration decreased from 6.33 ± 0.23 to 3.31 ± 0.41 m/s2, representing a 47.66% reduction, with t = 12.566 and dz = 2.29. Cutting time decreased from 65.77 ± 3.32 to 44.63 ± 3.59 s for ST41 and from 41.13 ± 1.83 to 20.40 ± 1.54 s for Aluminum 6061, corresponding to reductions of 32.1% and 50.4%, respectively. Based on the reported t statistics, all reductions were statistically significant (p < 0.001). The findings demonstrate that systematic reconditioning can substantially restore mechanical stability and cutting efficiency, providing a practical maintenance strategy for extending the service life of mechanical workshop of the Department of Mechanical Engineering, Politeknik Negeri Sriwijaya.

Abstract

Taliwang chicken is a traditional culinary icon of Lombok, Indonesia, and its supply chain, involving farmers, collectors, and restaurants, faces significant operational vulnerabilities. This study maps the native chicken supply chain using SCOR, identifies failure modes using FMEA, and determines risk priorities using AHP based on survey data from 58 respondents. The supply chain operates linearly from producers to restaurants. Integrating FMEA and AHP identifies price and market risks as the most dominant category (weight: 0.42), with live chicken price fluctuations ranking as the top-priority risk (weighted RPN: 161.28), followed by limited DOC supply, disease mortality, intermediary reliance, and low institutional support. Conclusion: Supply chain stability depends heavily on mitigating price volatility and securing stable inputs.

Abstract

This study implemented a solar-powered Internet of Things (IoT)-based smart fertigation system for hydroponic cultivation of romaine lettuce (Lactuca sativa var. longifolia) and pakcoy (Brassica rapa L.) using the Deep Flow Technique (DFT). The system integrated an ESP32 microcontroller, environmental sensors, and the Arduino IoT Cloud platform to enable real-time monitoring and automatic control of pH and nutrient concentration. During the 30-day cultivation period, the system maintained an average pH of 6.11, an average TDS concentration of 907.15 ppm, and an average water temperature of 29.22 °C, while the photovoltaic power system provided sufficient energy for continuous operation. Romaine lettuce reached average values of 15.76 leaves, 14.38 cm plant height, 13.25 cm leaf length, and 10.37 cm leaf width, whereas pakcoy achieved 19.39 leaves, 19.67 cm plant height, 12.31 cm leaf length, and 7.95 cm leaf width, with both crops outperforming the control treatment. The results demonstrate that the proposed system maintained stable growing conditions and supported continuous vegetative growth throughout the cultivation period. Therefore, the integration of IoT technology, automated fertigation, and solar photovoltaic energy provides an effective and sustainable solution for hydroponic vegetable production.
