Abstract

Palm sugar derived from sugar palm sap (Arenga pinnata Merr.) is widely used as a natural sweetener and contains various minor compounds that may contribute to its functional properties. Differences in processing intensity during the production of liquid, molded, and granulated palm sugar may induce chemical transformations affecting metabolite composition and antioxidant activity. However, comparative information linking processing level with these changes remains limited. This study evaluated the effects of different processing levels on the chemical characteristics and DPPH radical scavenging activity of palm sugar products. Antioxidant activity was determined using the DPPH method at a concentration of 1000 ppm, while metabolite profiling was conducted using untargeted LC–MS/MS Q-TOF in positive ion mode over an m/z range of 50–1200. Untargeted LC–MS/MS combined with principal component analysis (PCA) indicated differences in metabolite profiles among products, with liquid palm sugar showing the highest number of tentatively annotated features, followed by molded and granulated palm sugar. Increasing processing intensity was associated with shifts in metabolite composition, including reduced occurrence of oligosaccharide-related compounds and tentative detection of monosaccharide-related and heat-derived compounds such as maltol and phenolic-type derivatives. DPPH radical scavenging activity increased with processing level, reaching 39.23%, 55.93%, and 63.76% for liquid, molded, and granulated palm sugar, respectively. These findings suggest that thermal processing modifies the chemical profile of palm sugar and may improve its antioxidant-related properties under the conditions studied.

Abstract

As a national priority floriculture crop in Indonesia, the chrysanthemum has seen significant expansion across various production centers. Driven by rising aesthetic demands, it serves as a vital income stream for local farmers. However, most cultivation is managed by smallholders who face capital constraints and limited access to modern technology, often resulting in sub-standard yields. To address this, research into accessible, domestic technologies—specifically those utilizing local resources—is essential to enhance product quality and added value. Sustainable soil management through compost application offers a cost-effective solution for small-scale farmers to improve their welfare. This study evaluates the efficacy of recycling chrysanthemum harvest waste and leaf litter into organic fertilizer. The primary objective was to determine the optimal compost type and dosage to maximize productivity and flower quality under local environmental conditions. The research employed a greenhouse experiment using a Nested Design within a Randomized Complete Block Design (RCBD) with a factorial pattern. Statistical analysis revealed that: Raw Material Type: Had no significant effect on the observed growth variables, suggesting both chrysanthemum waste and leaf litter are equally viable bases for compost. Dosage: Within each material type, dosage had a significant to highly significant impact on all variables.. Chrysanthemum Waste Compost: A dose of 4 tons ha^-1 yielded the highest economic fresh weight at 53.40 g (a 17.70% increase over the control). Leaf Litter Compost: The highest yield occurred at 12 tons ha^-1, weighing 50.77 g (an 18.22% increase).

Abstract

Coffee is one of Indonesia's most strategic agricultural commodities, contributing significantly to national export revenues and serving as a primary income source for smallholder farmers. However, many small to medium-scale coffee producers still rely on traditional roasting methods that result in inconsistent temperature control, uneven roasting, and suboptimal product quality. This study aims to design, fabricate, and analyze the performance of a 3 kg capacity coffee roasting machine equipped with an LPG-based heating system and an electric motor-driven rotating drum. The machine was designed using Autodesk Inventor Professional 2025 and tested under varying operational conditions, including three roasting temperatures (200°C, 220°C, and 240°C), three roasting durations (10, 15, and 20 minutes), and two drum rotation speeds (40 rpm and 60 rpm). A total of 54 experimental trials were conducted to determine the effect of these variables on moisture content reduction and visual colour characteristics of the roasted coffee beans. Results indicate that the most optimal roasting condition was achieved at at 200°C, 20 minutes, and 40 rpm, yielding an average moisture content reduction of 12.3%, and at 220°C, 15 minutes, and 60 rpm, yielding an average moisture content reduction of 12.1% and producing dark roast beans with uniform colour and appearance. The study demonstrates that higher roasting temperatures combined with longer durations and faster drum rotation speeds significantly enhance moisture evaporation efficiency while maintaining uniform heat distribution. These findings provide practical guidelines for improving coffee processing quality among small-scale producers.

Abstract

The demand for sustainable alternative energy is rising due to fossil fuel depletion and environmental concerns. Anaerobic digestion (AD) of organic waste, such as cow manure, offers a promising solution by generating renewable biogas, managing waste, and mitigating greenhouse gas emissions. However, AD performance is frequently limited by process instability, the accumulation of inhibitory compounds like volatile fatty acids and ammonia, and the slow growth of methanogens. Biochar is a promising additive in AD systems because it can act as a microbial support medium, adsorb inhibitors, stabilize pH, and facilitate electron transfer, ultimately boosting methane production. This study provides a comparative evaluation of rice husk and palm kernel shell biochar under identical AD conditions to identify the optimal biochar type and dosage for methane enhancement. Biochar was applied at dosages of 5, 10, and 15 g/L. Substrate characteristics were analysed using COD, total nitrogen, TSS, and VSS, while biochar properties were characterized using SEM–EDX and BET. Biogas composition was determined by gas chromatography. Cow manure showed high suitability as substrate, with a COD of 53,333 mg/L and a VSS/TSS ratio of 94.32%. Biochar addition significantly improved methane concentration and process stability. Palm kernel shell biochar achieved the highest early methane content of 68.08% on day 15 at 5 g/L, indicating faster start-up performance. Rice husk biochar showed superior long-term stability, reaching 68.65% CH4 on day 20 at 15 g/L. These findings demonstrate that biomass-derived biochar is an effective additive for improving biogas quality and anaerobic digestion performance.

Abstract

Liquid waste generated from bleaching earth activation typically contains sulfuric acid and various metal ions, which pose environmental concerns but also offer potential as precursors for value-added chemical products. However, the utilization of this waste as a source for aluminum sulfate production remains limited. This study investigates the synthesis of aluminum sulfate (Al?(SO?)?) from bleaching earth liquid waste of PT. Madu Lingga Raharja uses kaolin as an aluminum source through a leaching–crystallization process. The leaching reaction was carried out by reacting 250 mL of liquid waste with kaolin at 100 °C for 60 minutes, followed by evaporation, crystallization, ethanol washing, and drying. The effects of kaolin mass (60–100 g) and stirring speed (250–450 rpm) on aluminum extraction were evaluated. The resulting products were characterized using X-Ray Fluorescence (XRF) for elemental composition and Scanning Electron Microscopy (SEM) for crystal morphology. The results show that increasing kaolin mass and stirring speed significantly enhance aluminum extraction due to improved mass transfer and reduced diffusion layer thickness. The optimum condition was obtained at 100 g of kaolin and a stirring speed of 450 rpm, yielding an Al?(SO?)? concentration of 12.50%, compared to the initial concentration of 7.7% in the untreated waste. SEM observations confirmed the formation of crystalline aluminum sulfate with plate-like morphology. Although the synthesis process improved the aluminum sulfate concentration, the obtained Al?O? content still does not meet the specification required by SNI 0032:2011, indicating that further purification or process optimization is required.

Abstract

This study examines the kinetics of aluminium sulfate (Al?(SO?)?) synthesis from pharmaceutical blister foil waste. The objective is to determine the reaction order, evaluate the effect of temperature on the reaction rate constant, and calculate the activation energy. The process involves dissolving aluminium in KOH, followed by reaction with H?SO? at 60–100°C for 20–60 minutes. The results show that conversion increases with higher temperature and longer reaction time. Kinetic analysis indicates that the reaction follows a first-order model with high linearity (R² = 0.9697–0.9974). The calculated activation energy is -4.506 kJ/mol, suggesting a rapid reaction with a low energy barrier, although deviations from the Arrhenius trend were observed. These findings highlight the potential use of blister foil waste as a raw material for aluminium sulfate production and provide insight into its reaction kinetics.

Abstract

Triazole-derived compounds are known to exhibit a variety of favourable biological activities, including antioxidant, anti-inflammatory, and antibacterial activities. Research on the potential of these compounds as antioxidant compounds was carried out theoretically through analysis of global reactivity parameters and measurement of antioxidant activity. The Density Functional Theory (DFT) method was used to study the molecular structure, global reactivity parameters, and hydrogen-atom release mechanism by calculating BDE, IP, PDE, PA, and ETE values. Antioxidant activity was expressed as the Inhibition Concentration 50% (IC50) values obtained from multilinear regression-based Quantitative Structure-Activity Relationship (QSAR) analysis. Validation was performed by comparing theoretical IC50 values with experimental values. The results show that molecule A is the most reactive, followed by molecules B, D, and C, which have the same theoretical IC50 value as the experiment. The interaction of the compounds with ROS and RNS radicals exhibited spontaneous reactions with negative ?G, reinforcing their potential antioxidant activity. This study confirmed that triazole-derived compounds have the potential to be further developed as effective antioxidants.Contribution to Sustainable Development Goals (SDGs): SDG 2 – Zero HungerSDG 3 – Good Health and Well-BeingSDG 12 – Responsible Consumption and Production

Abstract

Project implementation delays (schedule slips) not only affect project completion time but may also influence the adequacy of the project’s cost reserve (management reserve). This study aims to analyze the relationship between schedule slip and management reserve using the Earned Value Analysis (EVA) approach through the Estimate at Completion (EAC) and Variance at Completion (VAC) parameters. The study utilized planned S-curves, weekly progress reports, and the project contract value as the Budget at Completion (BAC) from a steel truss bridge construction project with a planned duration of 35 weeks and an actual completion time of 36 weeks. EVA parameters were evaluated at each reporting period. The Actual Cost of Work Performed (ACWP) was determined using the Project Implementation Budget (Rencana Anggaran Pelaksanaan/RAP) approach at 90% of the contract value, while the management reserve was established at 10% of the BAC. The results demonstrate that schedule slip is directly associated with an increase in the EAC value, leading to a reduction in the VAC value toward the management reserve threshold. Conversely, improvements in schedule performance increased the VAC value above the management reserve limit, indicating that the project’s cost reserve remained secure. Although the project experienced a one-week delay at completion, the VAC value remained within the management reserve threshold, confirming that the management reserve was still adequate. These findings indicate that project delays significantly affect the dynamics of management reserve conditions through changes in the estimated final project cost.
