Abstract

Plastic composite boards are made from OP-EFB (oil palm empty fruit bunches) which function as a filler, while HDPE (high-density polyethylene) plastic is used as a matrix. This study was conducted to analyze the physical and mechanical properties of plastic composite boards from empty palm oil bunches and high-density polyethylene plastic based on the effect of pressing temperature and determine the optimum pressing temperature. The temperature used for pressing were 140 oC, 150 oC, 160 oC, 170 oC, and 180 oC with the addition of coupling agents of MAH (maleic anhydride) and BPO (benzoyl peroxide) initiator. Based on the research that has been carried out, the physical and mechanical properties of the resulting plastic composite board are affected by differences in pressing temperature, with an optimum temperature of 170 oC the results of the testing were density, water absorption, MOR (modulus of rupture) compressive strength parallel to the surface and compressive strength perpendicular to the surface were 0.950 g/cm3, 0.090 %, 134.40 kg/cm², 465.80 kg/cm², and 50.40 kg/cm² respectively and the average test results for all treatments were 0.88 g/cm³, 1.00%, 130.20 kg/cm² and 426.96 kg/cm² respectively. The mechanical physical properties of plastic composites meet SNI 8154-2015 standard on WPC (wood plastic composites), except for MOR and perpendicular compressive constancy of the surface.

Abstract

Plastic waste poses a significant environmental challenge due to its non-biodegradable nature, emphasizing the need for sustainable alternatives like bioplastics from natural resources. This study develops and characterizes bioplastic films made from carboxymethyl cellulose (CMC) derived from bacterial cellulose synthesized using pineapple biowaste. Pineapple waste underwent fermentation to produce bacterial cellulose, which was chemically modified into CMC. Films were fabricated using CMC solutions with varying glycerol concentrations (0.5%, 1.0%, 1.5%, and 2.5% v/v). Characterization techniques, including SEM, XRD, FTIR, TGA, mechanical testing, and antibacterial assays, revealed that increasing glycerol concentrations smoothed the film's cross-sectional morphology, reduced crystallinity, and altered functional groups (e.g., new peaks at 870 cm⁻¹ and 935 cm⁻¹ attributed to C–H deformation). TGA indicated a four-stage thermal degradation pattern, with mass loss increasing from 77.2% to 88.4% at 2.5% glycerol, reflecting enhanced plasticization. Mechanical testing showed that the highest glycerol concentration increased film flexibility by 40.7 times while reducing tensile strength by 89.7%. Antibacterial activity against E. coli and S. aureus also improved with glycerol content. These results demonstrate the potential of CMC-based bioplastic films as sustainable packaging materials, offering customizable properties and promoting the value-added use of agricultural waste.

Abstract

Purpose: This work aimed to analyze the profiles of amino acids in the ficin enzyme isolated from Ficus aurata (Miq.), and to determine the efficiency of these amino acid concentrations under two types of drying – solar drying and freeze drying. Methodology: The enzyme ficin was obtained from fig tree, and the presence of amino acids was determined by UPL chromatography. The applied methods of drying were solar and freeze. However, the primary objectives were aimed at investigating the influence of these treatments on the level of amino acids present in all the samples. Results: The findings indicated that freeze drying techniques retained more amino acids in figs than was observed in the case of solar drying. In particular, the amount of L-glutamic acid in freeze drying was 2.39 mg/g, while that of solar drying was 1.43 mg/g. Similar results were observed in L-lysine and L-aspartic acid, which were relatively higher in freeze drying than solar drying, with concentrations of 2.43 mg/g and 2.55 mg/g, respectively, as opposed to 0.99 mg/g and 1.76 mg/g in solar drying. Besides, freeze drying showed better L-serine, L-phenylalanine, and L-histidine preservation. Findings: It was observed that freeze drying gave the best opportunity to reduce the loss of amino acid of the ficin enzyme. The drying method, in particular, resulted in a concentration of some important amino acids like L-glutamic acid, L-lysine, L-aspartic acid, L-serine and L-phenylalanine, and L-histidine as compared to solar drying. Novelty: This study focused on different types of solar energy and freeze energy economic systems in enzymatic activities in the ficin enzyme extracted from Ficus aurata (Miq.). The novel contribution of this research lies in its objective, which is to show how the drying methods used affected the retention of the most influential and critical amino acids in the enzymatic processes. Originality: The novel aspect of the study was the attachment of ultra vortices to different drying techniques, such as solar drying and freeze drying in select ficin enzymes from Ficus aurata. It opens up a new perspective toward the development of drying parameters for the enhancement of important enzymatic characters from this particular variety. Conclusion: This research considers the changes in amino acid content during the drying of ficin enzyme from Ficus aurata through different drying methods. It is shown that freeze drying enhances the retention of critical amino acids and is thus one of the most efficient methods for the enzymatic processing of this plant species. Type of Paper: Empirical research paper.

Abstract

Ficin is an enzyme derived from Ficus sp., recognized for its applications in the food and pharmaceutical sectors. Utilizing solar energy for enzyme drying has been shown to be economical and environmentally sustainable while preserving enzyme activity. This study aimed to determine the amino acid composition of crude ficin from Ficus padana Burm. f., and was extracted and dried with solar energy. The analysis of amino acid components was conducted using the UPLC technique. The results indicated the presence of numerous important amino acids, with L-aspartic acid being the highest concentrated at 1.85 mg/g and L-leucine at 1.41 mg/g. Significant quantities of L-glutamic acid (1.33 mg/g), L-serine (1.14 mg/g), and L-lysine (1.05 mg/g) were also identified. The solar drying process showed no significant loss of amino acids. The findings suggest that solar drying does not negatively impact the amino acid composition in fiction, therefore enhancing its practical significance, particularly for the food and pharmaceutical sectors.

Abstract

Rendang, a Minangkabau speciality, has been recognised as the world's most delicious food and Indonesia's national dish. However, Micro, Small and Medium Enterprises (MSMEs) producing rendang in Padang City face obstacles in meeting the commercial sterile food distribution permit standards, especially the calculation of the F0 value (heat sufficiency number). This service activity aims to foster and assist MSME players related to the sterilisation of commercial rendang products with export-level distribution quality by installing an IoT-based data logger on the retort tool to measure the F0 value in real time. The activity involved a pre-workshop, Focus Group Discussion, data logger installation, sterilisation training, and evaluation. It can be concluded that the measurement of the F0 value in the IKABOGA rendang product sterilisation process shows that the optimal sterilisation time is 40 minutes. This 40-minute sterilisation process can be used as a guide for the implementation of sterilisation by IKABOGA and initial data for fulfilling the requirements for a distribution permit but is sufficient to apply for a product distribution permit because it still requires other supporting data. This community service activity is the first step in developing an IoT-based sterilization process to be developed into a smart retort so that it can become an innovative tool that helps all MSMEs in the product sterilization process and meets the requirements for product distribution permits to a national scale.
