Abstract

An experimental study on the variation of heating rates in determining melting temperature using Differential Scanning Calorimetry (DSC) was conducted. This research aimed to investigate the effect of different heating rates on the determination of melting temperature using DSC, employing Indium Standard Reference Material (SRM) Lot BD147. The standard and sample were analyzed at heating rates of 5, 10, 15, 20, and 25°C/min. The resulted melting temperatures were analyzed using ANOVA, which revealed statistically significant differences. Heating rates of 5, 15, 20, and 25°C/min showed significant deviations from the standard rate of 10°C/min, indicating that 10°C/min is the most suitable rate for accurate melting temperature analysis based on ISO 11357-3.

Abstract

This study investigates the effect of roasting temperature and duration on sulphur removal and metal recovery from laterite residue obtained through atmospheric leaching of limonitic ore. The residue, characterized by high sulphur (7.43 wt.%) and iron (21.38 wt.%) content, was subjected to roasting at temperatures ranging from 500 °C to 800 °C for up to 120 minutes. XRD analysis revealed the presence of fayalite, hematite, enstatite, and jarosite, indicating stable sulphur-bearing and silicate phases. Results showed that complete sulphur removal (100%) was achieved at ≥750 °C within 30 minutes, while only partial removal (~45%) occurred at 500 °C. Iron and manganese recovery increased with temperature, reaching 28.46% and 26.50%, respectively, at 750 °C for 90 minutes. The improved recovery was attributed to the thermal decomposition of sulphates and oxidation of metal species to more leachable oxides. Roasting at 750 °C for 90 minutes was identified as the optimum condition, balancing sulphur elimination, metal recovery, and energy efficiency.

Abstract

Indonesia,  the world's largest cassava producer, has substantial potential in the tapioca industry, with major production centers in Lampung, South Sumatra, and Central Java. However, the industry also generates acidic wastewater with high Total Dissolved Solids (TDS), posing environmental risks. This study evaluates the effectiveness of fine-bubble aeration in reducing TDS and stabilizing pH in tapioca industrial wastewater. Aeration was carried out  at airflow rates of 2 and 5 L/min for  up to 60 minutes. Results showed a significant TDS reduction from ~1650 mg/L to 1000–1100 mg/L and a pH increase from 1.8 to 6.0–6.4. The 5 L/min rate achieved faster improvements. The findings  suggest that fine-bubble aeration enhanced  flocculation, oxidation of organic compounds , and the release of dissolved gases, providing  an efficient, economical, and environmentally friendly approach for tapioca wastewater treatment.

Abstract

Tofu industry wastewater in Indonesia contains high concentrations of organic pollutants, especially chemical oxygen demand (COD), which often exceed regulatory discharge limits due to the lack of effective treatment systems in small-scale production units. This study was conducted to evaluate the performance of durian peel as a low-cost adsorbent for COD removal. The adsorbent was prepared through carbonization at 300°C for 1 hour and activated using 30% H₃PO₄ for 24 hours. Batch adsorption experiments were conducted by varying contact time (0–150 minutes) and adsorbent dosage (0.2–1.0 g) at constant shaking speed (150 rpm). The result showed that activated durian peel demonstrated potential as an adsorbent for tofu wastewater, though its iodine number fell below the SNI 06-3730-1995 standard. The optimum condition was achieved at 90 minutes and 0.6 g adsorbent, resulting in 85.75% COD removal. Adsorption equilibrium data were analysis using Langmuir and Freundlich isotherm models. The Freundlich model provided a better fit (R² = 0.7663), indicating multilayer adsorption on a heterogeneous surface. These findings confirm the potential of durian peel as an effective biosorbent for tofu wastewater treatment under optimal adsorption conditions.

Abstract

The study aimed to compare the effects of using lime suspension and saturated lime water in the goat skin liming process, focusing on solution properties and skin characteristics. Liming was conducted at 26 °C for 60 minutes using a stirrer, with a skin-to-solution ratio of 1:10 and 2 g Ca(OH)₂ per 100 ml water. The initial pH values were 11.69 (lime suspension) and 11.62 (lime water), while initial conductivity was 7439 μS/cm and 4971 μS/cm, respectively. Observed variables included pH, TDS, electrical conductivity, precipitate weight, and skin weight gain and characteristics. Results showed no significant difference in pH between treatments during liming (p = 0.075) and no significant difference in skin weight gain (p = 0.067). However, solution conductivity differed significantly (p = 0.002), with lime suspension producing higher conductivity values. At the end of liming, precipitate weights were 1.53 g for lime suspension and 0.04 g for lime water, indicating more undissolved material in the suspension method. Skin characteristics, such as color, pH, and elasticity, were similar for both treatments. The findings suggest that while lime suspension and lime water produce comparable results in terms of pH and skin weight gain, they differ in conductivity and precipitate formation. The reduced precipitate in lime water indicates a cleaner process, which could contribute to clean production practices in the leather industry by minimizing solid waste without compromising leather quality. This research provides a scientific basis for considering saturated lime water as an alternative to lime suspension, potentially reducing environmental impact while maintaining product performance in goat skin leather processing.

Abstract

The rubber industry plays a crucial role in global manufacturing, with Indonesia being one of the leading natural rubber producers. One of the major processing defects encountered in rubber moulding is insufficient material loading, also known as a short shot, which can result in significant material waste and product rejection. This study investigates a repair method that involves adding a fresh rubber compound to patch defective rubber specimens. The method was applied by trimming a portion of the vulcanized rubber and replacing it with a fresh compound of the same formulation, followed by re-vulcanization. Mechanical properties, including tensile strength, elongation at break, tear resistance, hardness, and abrasion resistance, were evaluated following ASTM standards. Results indicated that repaired specimens generally retained acceptable mechanical performance, with abrasion resistance improving alongside increased patching percentages. These findings suggest that patching short-shot defects with fresh compound is a promising and cost-effective approach for reducing waste while maintaining product quality.

Abstract

Accurate shoe sizing plays a crucial role in ensuring comfort, performance, and consumer satisfaction, particularly for women whose foot shapes exhibit considerable anatomical variability. To address this challenge, this research proposes a data-driven modeling framework for developing a women’s shoe sizing system based on three-dimensional foot scanner data. The study was carried out through a systematic process consisting of data preprocessing, clustering using the K-Means algorithm, and evaluation of the clustering performance. The clustering analysis identified four optimal clusters within the dataset, representing distinct patterns in foot dimension measurements. The evaluation result, with a Silhouette Score of 0.25, indicates a moderate yet acceptable level of cohesion and separation among the clusters. These findings demonstrate that the proposed model can effectively capture the underlying structure of women’s foot morphology, providing a scientific foundation for establishing more accurate, customized, and ergonomically appropriate shoe sizing standards.
