Abstract

Molasses Multinutrient Soft (MMS), an innovative alternative livestock feed formulated from agro-industrial waste products such as molasses, tofu dregs, coconut cake, rice bran, salt, and a mineral mix, was evaluated for nutrient stability during storage. Feed storage was conducted on a laboratory scale. This study employed a completely randomized design across 0, 10, 20, and 30-day storage periods, revealing that storage significantly influenced (p < 0.05) key quality parameters, including moisture, dry matter, organic matter, ether extract, and acid-insoluble ash. While crude protein and nitrogen-free extract remained stable, significant changes (p < 0.05) were observed in fiber fractions (neutral detergent fiber, acid detergent fiber, and hemicellulose) and phosphorus content. These alterations, predominantly driven by microbial activity and environmental conditions, suggest that MMS maintains safe storage limits for up to 30 days. A strong correlation between moisture and dry matter was observed during storage, a key attribute that determined the feed's nutritional quality. This study offers valuable insights into the post-production quality of alternative feeds, underscoring MMS's potential as a viable and promising feed option for smallholder livestock farmers, particularly under minimal storage conditions. Further investigation is required regarding the effects of prolonged feed storage on the physical and chemical characteristics of MMS.

Abstract

Road infrastructure is a vital component in supporting regional economic growth and social connectivity, including the Gayam–Sidorejo road section in Kediri District, which functions as a primary collector road. This study aims to identify pavement distress along the 8.383 km Gayam–Sidorejo road segment, determine its functional condition using the Surface Distress Index (SDI) method, and visualize the spatial distribution of the distress through Geographic Information System (GIS) mapping. The methodology involved primary data collection through field visual surveys to identify distress parameters, including crack area, crack width, number of potholes, and rutting depth, in accordance with the guidelines of the Directorate General of Bina Marga. These data were then integrated into a spatial database using ArcGIS software to produce thematic maps of road conditions. The evaluation results show that the SDI values for the Gayam–Sidorejo road section range from 10 to 45. The lowest SDI value of 10 was recorded at STA 2+000–2+500, while the highest value of 45 was found at several locations, including STA 1+000–1+500 and STA 8+000–8+383. Based on the analysis, all road segments are classified in "Good" condition. Consequently, the recommended treatment program for the entire corridor is Routine Maintenance. The integration of the SDI method into GIS proved effective in transforming tabular data into dynamic visual representations, facilitating the analysis of distress patterns and supporting more efficient decision-making in road maintenance management.

Abstract

Food is a priority human need for survival. The evaluate population's level of food security in Ogan Komering Ulu (OKU) Regency, South Sumatra. This study includes mapping and measuring food vulnerability based on the main indicators: availability, accessibility, and food utilization. The purposive sampling method was used to select the research location, which covers 157 villages and 13 sub-districts in OKU Regency. Primary data were obtained through field observations and surveys, while secondary data were obtained from various official sources. The results showed that the Food Security Index (IKP) of OKU Regency was in the moderate category, with variations in the level of food security in each sub-district. The vast agricultural land increases food availability, but low nutritional awareness and stunting rates in children challenge good food accessibility and utilization. In addition, the analysis found groups of people vulnerable to food insecurity, especially in remote areas. These findings will help policymakers create better strategies to address food security issues in the OKU Regency.

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.
