Abstract

The accumulation of food packaging waste, specifically styrofoam, has become a significant environmental pollutant due to its 500-year degradation period and hazardous chemical content. To address this issue, biodegradable foam (biofoam) made from natural polymers such as starch and cellulose offers a sustainable, economical alternative to conventional styrofoam. This research aims to synthesise and characterise biodegradable foam (biofoam) from cassava pulp and cellulose from sugarcane bagasse as an eco-friendly alternative to styrofoam. Biofoam was synthesised using cassava pulp, cellulose, polyvinyl alcohol (PVA), and glycerol, with varying starch-to-cellulose ratios (1:0.2 to 1:1) and mixing times (5 to 30 minutes), followed by thermopressing at 150°C. Characterization included tensile strength, water absorption, biodegradability, FTIR, and SEM testing. Results showed that the 1:1 ratio with 30-minute mixing give the best properties: 10.4575% water absorption, 41% biodegradability in 30 days, and 5.4916 MPa tensile strength. Water absorption and biodegradability met SNI 7188.7:2016 and ASTM D5988 standards. Although the tensile strength (5.4916 MPa) exceeded commercial styrofoam, it did not meet the 29.1600 MPa SNI requirement. FTIR confirmed the presence of hydroxyl, aliphatic, and carbonyl groups. SEM revealed clumping and cavities on the surface due to incomplete homogenization and starch gelatinization.

Abstract

Germination in red rice aims to improve its quality, particularly its texture. However, this germination process produces relatively long sprouts that can interfere with the quality of red rice when consumed. Therefore, calcium chloride is utilized with different application patterns to suppress sprout elongation while simultaneously enhancing calcium accumulation. Red rice (Inpari 24 variety) was germinated using a partially circulated germinator with variations in calcium chloride treatment patterns and germination duration. The physicochemical characteristics of ungerminated and germinated red rice exhibited differences, specifically in germination quality, calcium, color, pasting profile, and total sugar content. Germination without calcium chloride treatment and germination with full calcium chloride treatment at the initial stage significantly affected the germination rate, sprout length, calcium, and pasting profile of the red rice. Germination under each distinct calcium chloride application pattern successfully suppressed red rice sprout elongation. The results indicated that full calcium chloride treatment at the initial stage produced the lowest germination rate and sprout length (74.67–88.00% and 0.66–1.24 mm, respectively). Germination with calcium chloride treatment at the intermediate-stage and in a gradual manner reduced the sprout length of the red rice. The treatment with calcium chloride also increased calcium levels, an essential mineral for humans. Full treatment of calcium chloride at the initial stage yielded germinated red rice with the highest calcium (228.06–252.20 mg/100g). The different calcium chloride treatment patterns did not significantly affect the color, pasting profile, and total sugar of the germinated red rice; however, an increase was observed from the ungerminated red rice to the germinated red rice.

Abstract

This study evaluates the technical and economic characteristics of cement boards made from sawdust and coconut husk fiber waste using MgCl? as a catalyst. The cement boards were produced using the cold-pressing method with dimensions of 35 cm × 35 cm × 1 cm. The composition of the cement board consists of 25% sawdust, 15% coconut husk fiber, and 60% cement, along with a MgCl? catalyst amounting to 2.5% of the cement weight. Technical testing adheres to SNI 03-2105-2006, and the economic analysis employs the full costing method to calculate the cost of goods sold and the break-even point. Test results indicate that the physical parameters of the cement board—namely density, moisture content, and total expansion—meet the reference limits specified in SNI 03-2105-2006. Mechanically, the modulus of elasticity meets the reference limits in SNI 03-2105-2006, while the modulus of rupture falls below the minimum reference limit. The economic analysis in this study indicates a production cost of Rp10,749.41 per unit and an estimated selling price of Rp14,000.00, with the break-even point reached at sales of 74 units per year. Cement boards made from sawdust and coconut fiber waste have dimensional stability and stiffness that meet standards, but improvements in mechanical strength and interparticle bonding still require optimization in the production process.

Abstract

Marshmallows are soft, chewy candies characterized by their light, foamy texture. They are typically formulated with gelling agents like gelatin, pectin, or starch, and have a water content of 12-20%. Their composition primarily includes sucrose and liquid glucose, resulting in a mildly sweet taste. This study explores enhancing marshmallows’ nutritional value by incorporating corn silk extract, an inexpensive and abundant corn by-product that is often underutilised. Corn silk is rich in antioxidants and possesses a subtle aroma and flavor, making it an ideal natural additive. This research aimed to evaluate the impact of corn silk extracts on the chemical and organoleptic properties of marshmallows and identify the selected formulation. Using a completely randomized design (CRD) with five concentrations of corn silk extracts (P1: 10%, P2: 20%, P3: 30%, P4: 40%, and P5: 50%) and four repetitions. The study analyzed water, ash, sucrose content, pH, and organoleptic properties (color, texture, and taste). Results indicated that adding corn silk extracts significantly (P<0.05) affected all tested parameters. The selected formulation was P1 (10% corn silk extracts). This formulation yielded marshmallows with a water at 16.18%, an ash at 0.91%, a sucrose content at 31.78%, and a pH at 6.80. Organoleptically, P1 marshmallows scored highly for color (6.32, very much like-very much like), texture (5.32, like-very much like), and taste (5.20, like-very much like). Corn silk extracts potential to enhance marshmallow characteristics and provide an innovative use for this agricultural byproduct.

Abstract

Cascara, a coffee husk by-product of coffee processing, has recently gained attention as a refreshing beverage. This study aimed to characterize the sensory profiles of commercial cascara products derived from different post-harvest processing methods using Check-All-That-Apply (CATA), to identify key sensory attributes driving consumer perception, and to segment consumer preferences based on sensory responses. Five commercial cascara products were evaluated, namely natural Arabica cascara, natural Robusta cascara, fully washed Arabica cascara, honey-processed Arabica cascara, and wine-processed Arabica cascara. The results revealed that cascara brews exhibited distinct sensory profiles, significantly influenced by coffee variety and post-harvest processing methods (p < 0.05). Lemon flavor, dried fruit aroma and flavor, and fermented aroma were identified as the main drivers of liking, whereas bitterness negatively affected consumer preference. Naturally processed cascara Arabica was most preferred among panelists, and preference was significantly influenced by gender. These findings provide new insights into the development of cascara-based beverages as refreshing drinks Contribution to Sustainable Development Goals (SDGs):SDG 3: Good health and well-beingSDG 8: Decent work and economic growthSDG 12: Responsible consumption and production

Abstract

Mechanical extraction of peanut oil using an oil press machine is a relatively simple and environmentally friendly method that can be applied on a small- to medium-scale. This study aimed to determine the characteristics of peanut oil and meal produced by an oil press. The research method employed was experimental and involved a descriptive analysis of the quality parameters of the oil and meal. For the oil, the observed parameters included yield, color  (CIELab), and density. For the peanut meal, the observed parameters were moisture, fat, and protein content. Results showed that increasing the extraction temperature increased the yield and density of peanut oil, with the highest values obtained at 200 °C. The lightest oil color was obtained at 180 °C, as indicated by the highest L* value. For the peanut meal, increasing extraction temperature decreased moisture content, with the lowest at 200 °C. However, the meal's residual fat content increased significantly at 200 °C, indicating decreased extraction efficiency at excessively high temperatures. The protein content of the meal ranged from 45.84% to 48.73% and remained relatively stable across all temperature treatments. These results indicate that the characteristics of the resulting peanut oil and meal are affected by extraction temperature; therefore, the extraction temperature must be selected according to the intended use of the final product.

Abstract

Sulfate (SO?²?) is a major inorganic pollutant in distillation washwater with concentrations of 4,000–6,000 mg/L and the potential to form H?S during anaerobic processes. This study investigated sulfate removal using biochar derived from biogas digestate. The biochar was produced by carbonization at 600 °C for 1.5 h and applied as an adsorbent with masses of 1–3 g and contact times of 20–100 min. BET, SEM-EDX, and FTIR analyses showed that the biochar had a mesoporous structure with a surface area of 140 m²/g, pore volume of 0.155 cm³/g, pore diameter of 4.43 nm, mineral content of Ca, K, and Mg, and active functional groups. Adsorption efficiency increased until reaching an optimum at 2 g adsorbent and 60 min contact time with an efficiency of 88.7605%, then decreased due to adsorption equilibrium and ion competition. Isotherm analysis indicated that the adsorption process followed the Langmuir model with a maximum adsorption capacity of 232.558 mg SO?²?/g, indicating monolayer adsorption on a homogeneous surface.

Abstract

This study aims to analyze the effect of tray spacing on increasing dissolved oxygen and to evaluate the performance of tray aerators in reducing dissolved Fe and dissolved Mn. The study was conducted in Rungkut District, Surabaya City using tray aerators as aeration reactors. This study is divided into 2 stages: optimization and application. The optimization stage analyzes the effect of tray spacing in increasing dissolved oxygen. This stage uses variations of 30 cm, 40 cm, and 60 cm spacing. The application stage employs the optimal tray spacing to reduce Fe and Mn in well water. The results showed that a tray spacing of 30 cm can increase dissolved oxygen up to 0.6 mg/L. Tray aerators used in the application stage can reduce Fe and Mn levels in well water by 39.77% and 20.19%, respectively. The results of tray aerator aeration have not met the quality standards of the Regulation of the Minister of Health of the Republic of Indonesia No. 2 of 2023, namely 0.2 mg/L and 0.1 mg/L. This shows that aeration is not enough to reduce Fe and Mn in well water, so it requires additional processes such as adsorption and filtration.

Abstract

The increase in motor vehicle activity along Tandes Street to Raya Manukan Kulon Street, Surabaya, has the potential to reduce air quality due to carbon monoxide (CO) emissions. This study analysed the dispersion of CO using the AERMOD modelling system and direct field measurements at several observation points. The modeling results showed a maximum CO concentration of 14,972 µg/m³, while field measurements reached 16,749 µg/m³. Model validation using the Root Mean Square Percent Error (RMSPE) method produced a value of 19.23%, indicating that the AERMOD model has good accuracy in representing actual field conditions. The differences between simulation and observation results were influenced by meteorological conditions, traffic variations, and input data uncertainty. Overall, traffic activity significantly affects CO concentrations in the study area, although these concentrations remain within applicable air quality standards.

Abstract

The increasing demand for renewable energy necessitates innovative solutions utilizing abundant agricultural waste. This study investigates the development of a novel hybrid liquid electrolyte that combines crude bioethanol derived from oil palm empty fruit bunches (OPEFB) with natural seawater for sustainable bio-battery systems. The main novelty lies in leveraging the synergistic effect between the stable, polar organic medium of OPEFB bioethanol and the high conductivity of seawater (49.87 mS/cm), thereby eliminating reliance on synthetic chemicals. The OPEFB underwent delignification (6% NaOH) and hydrolysis prior to fermentation. Gas Chromatography-Mass Spectrometry (GC-MS) confirmed the successful bioconversion into crude bioethanol (39.84% relative peak area). Electrochemical evaluations using a Zn/Cu electrode configuration revealed that the delignification-based solution at an optimal 70:30 (bioethanol-to-seawater) mixture ratio generated a maximum power output of 0.84 mW. Significantly, this research provides a dual-solution approach: valorizing massive lignocellulosic waste while advancing eco-friendly energy storage. Practically, the formulated hybrid bio-battery is highly viable for ultra-low-power applications, demonstrably capable of continuously powering small Light Emitting Diodes (LEDs) for up to 24 hours and mini DC fans for 9 hours.
