Abstract

Pupuk organik cair (POC) adalah pupuk cair hasil fermentasi dengan bahan limbah organik hasil pertanian dan limbah organik rumah tangga dan dibantu dengan EM4, pupuk ini merupakan salah satu inovasi bagi masyarakat yang ketergantungan terhadap pupuk kimia yang memiliki harga yang cukup mahal. Kandungan pupuk organik cair ini pada dasarnya hampir sama dengan pupuk kimia dimana unsur yang terdapat didalam nya berupa unsur C, N, dan H yang dapat berguna bagi kesuburan tanah. Batang pisang menjadi salah satu bahan yang banyak digunakan dalam pembuatan pupuk organik cair ini, dikarenakan populasinya yang cukup melimpah di Desa Talang Karet, Kabupaten Kepahiang, yang mayoritas penduduk nya bermata pencaharian sebagai petani baik kebun maupun hortikultura. Pelatihan ini bertujuan untuk memberikan pengetahuan kepada masyarakat terkait dengan pentingnya beralih dari pupuk kimia pada pupuk organik, sehingga dana yang dialokasikan masyarakat tidak terlalu berlebihan pada pupuk, namun dapat di alokasikan pada kepentingan kebun lainnya. Tingkat keberhasilan dari pelatihan ini dinilai dari pupuk yang dihasilkan, mencakup kekentalan, dan pH.

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.
