Abstract

Biothermoplastic composites are mixtures of two or more polymers from biological materials with other materials that can melt when heated and harden again when cooled. The formation of packaging trays from biothermoplastic composites is greatly influenced by many factors including temperature and molding time. This study aims to determine the effect of molding temperature and time on the characteristics of tray packaging from thermoplastic starch, thermoplastic glucomannan and latic polyacud biothermoplastic composite raw materials. This study used a 2-factor with 9 treatments, each treatment repeated as many as 2. The first factor is temperature (S) which consists of 3 temperature levels 130  (S1), 145  (S2), 160  (S3). The second factor is time (W) which consists of 3 levels of 30 seconds (W1), 45 seconds (W2), 60 seconds (W3). The results showed that temperature and molding time significantly affected the tensile strength, elongation at break, elasticity, thickness development, density, biodegradation time and leakage test of TPS/TPG/PLA biothermoplastic composite tray packaging. The best tray packaging was obtained at molding with a temperature of 160 ℃ and a time of 45 seconds with a tensile strength value of 42.20  MPa, elongation at break value of 0.70%, modulus young of 6, 12 GPa, swelling of 0.47%, density of 1.31 g/cm3, biodegradation time of 24.00 days and leakage test (not leak). However, modulus young, elongation at break and density have not met the standards set.

Abstract

Biotermoplastic is a one of the innovation to improve the physical and mechanical properties of bioplastics. This study aims to determine the effect of the type and concentration of compatibilizer on the characteristics of biothermoplastic composites and to determine the type and concentration of the right compatibilizer to produce the best characteristics of biothermoplastic composites of thermoplastic starch/thermoplastic glucomannan/polylactic acid (TPS/TPG/PLA). This research utilizes a Completely Randomized Design (CRD) with 6 treatments, namely J1KI (maleic acid anhydride 5%), J1K2 (maleic acid anhydride 7,5%), J1K2 (maleic acid anhydride 10%), J2K1 (stearic acid 5%), J2K2 (stearic acid 7,5%), and J2K3 (stearic acid 10%), with 3 replications. The variables observed in this study were tensile strength, elongation at break, elasticity, swelling, density, melting point and biodegradation time. The data were analyzed by analysis of variance (ANOVA) and further tested using the Honestly Significant Difference (HSD) test. The results showed that the type and concentration of compatibilizer had a very significant effect on the values ​​of tensile strength, elongation at break, elasticity, swelling, density, melting point and biodegradation time. The best characteristics of biothermoplastic composites of thermoplastic starch/thermoplastic glucomannan/polylactic acid were obtained by using 10% anhydrous maleic acid compatibilizer with a tensile strength value of 30.43 MPa, an elongation at break of 0.90%, elasticity of 3.38 GPa, swelling of 0.51%, density of 1.52 g/cm3, melting point of 149.77oC and biodegradation time of 17.667 days.

Abstract

Determination of biothermoplastic composite formulation is essential to produce the best biothermoplastic composite characteristics and meet the standards. This study seeks to identify the characteristics of the best biothermoplastic composites in variations of thermoplastic starch formulations, thermoplastic glucomannan and polylactic acid. This study used a Completely Randomized Design (CRD) with 5 treatments of TPS/TPG formulas with PLA, namely 90:10, 80:20, 70:30, 60:40, 50:50. There were 4 repetitions of each treatment, for a total of 20 experimental units. The variables observed were tensile strength, elasticity, elongation at break, melting point, biodegradation, swelling and density. The diversity analysis showed that the formulation of thermoplastic starch-thermoplastic glucomannan and polylactic acid had a very significant effect on the tensile strength, elasticity, elongation at break, melting point, biodegradation, swelling and density of biothermoplastic composites. Biothermoplastic composites with the formulation of TPS/TPG: PLA = 50:50 produced the best characteristics with a tensile strength of 26.71 MPa, elasticity of 932.04 MPa, elongation at break of 2.89%, biodegradation of 15.25 days, melting point of 152.65oC, density of 1.26 g/cm3 and swelling of 1.32%.

Abstract

Tourism destinations in Indonesia generate food waste in significant number and contribute to 39.78% of total national food waste (FW). However, characterization data for bioprocess applications and evaluations of waste processing remains limited. This study aimed to quantify and characterize food waste from tourism destinations to assess baseline conditions for circular economy and bioprocess implementation. FW was systematically collected and analysed from Jatim Park 2 tourism facilities over Oktober 2024 to January 2025. Food waste generation rates, physical composition, and chemical properties were determined. Existing waste management framework assessed using observational method and stakeholder interviews. Average of 89.2kg/day food waste was generated from 1 main restaurant and 16 food seller in Jatim Park 2 area and predicted to increase up to 121.5kg/day in weekend or holiday. Average moisture content was 72.71%, total solid of 27.29%, and C/N ratio of 46.40. Existing waste processing was limited to collect and transport from waste collection point to waste storage point only. Furthermore, external contractors were contracted to provide waste and FW disposal services. Unfortunately, their partners do not have sufficient disposal service capacity to handle the volume of waste and FW produced. This inadequacy results in the accumulation of waste and FW to a significant volume. In general, the results indicate that tourism FW represent significant untapped resources. The baseline data provides foundation for suitable FW management strategies. Implementation of circular economy could transform FW streams into valuable products contributing to sustainable tourism development.

Abstract

Energy is an important factor supporting the fulfillment of human life needs and the economy in both developed and developing countries, including Indonesia. One energy source that has potential for development and implementation in Indonesia is biomass. Livestock manure is one of the biomasses available in Indonesia that contains methane gas which can be used as a biogas energy source. Initial substrate characterization is very important for understanding the potential and efficiency of anaerobic fermentation processes in biogas production. Cattle manure as lignocellulose biomass has physical and chemical properties that affect the rate of organic degradation and methane yield. The CHNSO test method uses CHNSO Elemental analyzer, Hemicellulose test uses the Chesson method, Total N test uses the Kjeldahl method, P and K methods follow SNI 7763: 2018. Research results showed C 41.27%, H 4.63%, N 0.954%, S n. a, O 18.01%, N-Total 1.365, P₂O₅ 0.797, K₂O 0.594, Hemicellulose 15.788, Cellulose 34.62, Lignin 29.85, Lignocellulose 80.26, Dry Matter 93.97, Ash Content 18.26, Crude Protein 7.43, Crude Fiber 35.85, Crude Fat 0.28, Methane Yield Content 109.80. Cattle manure has high lignocellulose content and optimal C/N ratio with methane yield of 109.80 mL/g VS, demonstrating potential as a renewable energy substrate as well as raw material for organic fertilizer rich in macro nutrients.
