Abstract

This research evaluates the use of natural coagulants, such as soursop and Aegle marmelos (Maja), in the latex coagulation process of the GT 1 clone type, compared with chemical coagulants such as formic acid and acetic acid, to gain an understanding of the characteristics of the rubber produced. Three types of crumb rubber (SIR 3 CV, SIR 3L, and SIR 3 WF) are produced from latex, while SIR 5, SIR 10, and SIR 20 are produced from treated latex coagulum. Rubber quality criteria are explained in the Indonesian Rubber Standard (SIR 3L/3WF) SNI 06-1903-2011. The use of natural coagulants, especially soursop, and Maja, in the coagulation of GT 1 clone latex shows an influence on coagulation time, Dry Rubber Content (DRC), initial plasticity (Po), Plasticity Retention Index (PRI), ash content, dirt content, and substance content evaporate. The results showed that natural coagulants had slower coagulation times, higher DRC values ​​(especially in maja), and better PRI values ​​compared to chemical coagulants. Despite having higher ash content, dirt content, and volatile matter content, all types of coagulants meet rubber quality standards. This research provides in-depth insight into the potential and advantages of natural coagulants, especially soursop, and maja, in the environmentally friendly rubber industry. In addition, analysis of rubber characteristics, such as plasticity, resistance to heating, and content of certain components, provides a comprehensive understanding of the impact of the use of natural coagulants on rubber quality.

Abstract

To prevent the transmission of COVID-19, the World Health Organization recommends the implementation of health protocols including using disposable masks. The use of disposable face masks has an impact on the emergence of mask waste in aquatic environments which results in pollution of water sources by microfibers. Degradation by indigenous microorganisms can be one of the solutions for handling waste that is environmentally friendly and cost effective. In this study, bacteria were isolated from the coast of Lampung Bay which was polluted with plastic waste and masks. Bacterial isolates were characterized by morphological and biochemical tests before the selected one being used for degradation. After seven days of incubation, gravimetric analysis showed that the mask pieces increased in weight when compared to the control. However, the degradation process can be shown by the results of Scanning Electron Microscope (SEM) analysis which shows damage in the form of holes on the surface of the mask when compared to the new mask and the control. SEM images also showed the presence of bacterial biomass remnants attached to the surface of the mask. Based on the results of this study, Lampung Bay indigenous microorganism isolate showed potential as a degrader of disposable face masks.

Abstract

The use of disposable face masks during the Covid-19 pandemic has resulted in the emergence of mask waste polluting aquatic environments due to poor management. This waste will decompose into microfibers which accumulate in aquatic organisms. The combination of vermiremediation with the addition of degrading microorganisms can be one of the solutions for treating disposable mask waste. In this study, Eudrilus eugeniae, an earthworm species, was used in vermiremediation with variations in the treatment by adding indigenous bacterial isolate from the waters of Lampung Bay which has been proven able to degrade disposable masks. The results showed that the vermiremediation technique can be used to degrade disposable masks, indicated by a decrease in mask weight after incubation for two months in the amount of 0.03 grams and 0.05 grams for the treatment with the Eudrilus eugeniae and a combination of bacterial isolate respectively against the initial weight. Lampung Bay indigenous bacterial isolate helped accelerate the mask degradation process in the combined vermiremediation technique. The carbon, nitrogen, phosphorus, and potassium contents of the compost produced by the vermiremediation process have met the SNI for compost from domestic organic waste.

Abstract

The designation of COVID-19 as a global pandemic led to an increased use of single-use face masks, which result in waste that is difficult to degrade and has the potential to release microplastic fibers into the environment. This study aims to examine the im-pact of adding pineapple peel liquid waste (LCN) as a growth medium for the biodeg-radation of single-use face masks by bacterial isolates obtained from the waters of the Lampung Bay. The study investigates how LCN affects the efficiency of mask degra-dation by microorganisms, as well as how the ratio of LCN mixed with other growth media, such as Nutrient Broth (NB), influences the degradation process. The biodeg-radation process was carried out using a biostimulation technique, where bacterial iso-lates were incubated in media containing LCN at a 1:1 ratio. The degradation process lasted for 15 days, with the results being analyzed using gravimetry and Fourier-Transform Infrared Spectroscopy (FTIR). Gravimetric results showed a greater weight reduction in treated masks compared to the control masks. FTIR analysis also indicat-ed changes in the intensity of functional groups in the degraded layers of the masks, as well as the emergence of C≡C functional groups in the second and third layers. This study demonstrates that the addition of LCN can accelerate the biodegradation of sin-gle-use face masks, offering a new approach for managing mask waste.

Abstract

Agarwood powder, a by-product of agarwood processing, still contains valuable aromatic compounds, including sesquiterpenoids and chromones, used in aroma-based industries. However, its utilization remains limited due to the lack of simple and efficient extraction strategies. This study aims to investigate the effects of prolonged maceration time and agitation on the yield, acid value, and functional groups of agarwood resin extracted from agarwood powder using ethanol at a 1:3 (w/v) ratio, under agitated and non-agitated conditions for two and seven months. The results demonstrate that maceration time and agitation influence resin recovery and quality. The highest resin yield (4.537% v/w) was obtained after seven months of maceration without agitation, indicating that static conditions more effectively promote gradual diffusion and accumulation of high-molecular-weight resin compounds while minimizing mechanical and oxidative degradation. In contrast, agitated maceration resulted in lower yields (0.228–0.279% v/w) and higher acid values (10.9±0.85 mg NaOH/g), suggesting accelerated hydrolytic reactions and increased formation of free fatty acids, which may adversely affect resin quality. FTIR analysis showed that the principal functional groups of agarwood resin remained relatively stable under different maceration conditions. However, minor shifts in the O–H absorption bands suggested slight chemical changes, possibly related to enhanced hydrogen bonding and the formation of carboxylic acid groups during prolonged agitated maceration. These findings indicate that long-term static maceration has potential as a simple, low-energy, and sustainable extraction method to improve the utilization and commercial value of agarwood powder waste in resin-based industrial applications.

Abstract

The partner’s main problem in this community service program was the suboptimal utilization of young coconuts in Cupel Village, Negara District, Jembrana Regency, despite their abundant availability and high economic potential. The priority problems faced by the PKK women’s group included limited knowledge of young coconut processing, production skills, the use of simple equipment, packaging techniques, and digital marketing. This community service program aimed to improve the capacity of coastal communities to process young coconuts into Jelly Coco, a value-added product with potential as an alternative source of income. The program was implemented using a participatory approach based on Participatory Rural Appraisal (PRA), which included needs identification through surveys and interviews, workshops, hands-on Jelly Coco production practice, Instagram-based marketing assistance, and evaluation through pre-test and post-test assessments. The activity involved 35 participants consisting of PKK members and representatives of the local community. The evaluation results showed an increase in the average achievement of participants’ knowledge and skills indicators from 72.65% in the pre-test to 95.57% in the post-test. Participants were also able to understand the functions of production equipment, the stages of Jelly Coco production, packaging techniques, and demonstrated strong interest in developing household-scale businesses based on young coconuts. Therefore, Jelly Coco production training effectively strengthened the technical and entrepreneurial capacity of the Cupel Village community. However, program sustainability still requires further support in marketing development, production equipment availability, and regular business mentoring.

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.
