Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh koagulan alami (lemon, jeruk bali, dan asam jawa) serta koagulan kimia (asam formiat) terhadap karakteristik karet Klon GT 1. Koagulan alami diekstrak dan disaring untuk meminimalkan kandungan bulir dan kotoran sebelum diaplikasikan ke dalam lateks dengan rasio berat 1:2, sedangkan konsentrasi asam formiat yang digunakan adalah 2%. Hasil penelitian menunjukkan bahwa waktu koagulasi menggunakan koagulan alami lebih cepat dibandingkan koagulan kimia, dengan lemon menghasilkan dry rubber content (DRC) tertinggi. Analisis plastisitas karet menunjukkan adanya variasi antara jenis koagulan, di mana jeruk bali memiliki nilai plastisitas awal (Po) tertinggi. Meskipun kadar abu pada karet yang dihasilkan oleh koagulan alami lebih tinggi, kadar kotorannya lebih rendah dibandingkan dengan koagulan kimia, khususnya asam formiat. Walaupun biaya produksi menggunakan koagulan alami lebih tinggi akibat faktor musiman dan proses pra-perlakuan, karet yang dihasilkan, terutama dari jeruk bali, memiliki karakteristik yang jauh lebih unggul dibandingkan dengan karet yang dihasilkan menggunakan koagulan kimia. Penelitian ini menyimpulkan bahwa koagulan alami berpotensi menjadi alternatif efektif untuk meningkatkan kualitas lateks Klon GT 1, serta memberikan wawasan bagi industri karet dalam memilih metode koagulasi yang lebih berkelanjutan dan berkualitas tinggi.

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.
