Abstract

Tanaman kelapa merupakan salah satu komoditas sektor perkebunan yang mempunyai peran dan kontribusi penting bagi Kabupaten Lampung Selatan. Umumnya, tempurung kelapa sebagai hasil samping perkebunan hanya digunakan sebagai bahan baku pembuatan arang aktif. Mempertimbangkan potensi limbah tempurung kelapa yang belum dimanfaatkan secara maksimal, tim Pengabdian kepada Masyarakat (PKM) Institut Teknologi Sumatera (ITERA) merancang dan membangun tungku karbonisasi dan alat distilasi di desa Muara Putih, Natar yang menghasilkan produk arang aktif dan asap cair. Asap cair dapat dimanfaatkan sebagai biopestisida dan koagulan alami penggumpal lateks. Kegiatan sosialisasi pemanfaatan asap cair sebagai koagulan alami lateks dilaksanakan di Stasiun Penerimaan Lateks PT. Perkebunan Nusantara VII Unit Kedaton. Dilakukan demonstrasi langsung untuk membandingkan penggumpalan lateks oleh asap cair dan asam formiat sebagai koagulan kimia yang umum digunakan. Asap cair sebagai koagulan alami lateks memberikan waktu koagulasi yang lebih cepat dan menghasilkan lebih banyak koagulum. Sosialisasi ini memberikan informasi tentang nilai lebih pemanfaatan asap cair sebagai koagulan lateks kepada petani karet. Tungku karbonisasi dan unit distilasi yang dibangun oleh tim PKM mengolah limbah tempurung kelapa menjadi asap cair yang dapat digunakan sebagai alternatif koagulan lateks.

Abstract

The aim of this research was to determine the properties of the PB 260 clone rubber using the Averrhoa type coagulant. The natural coagulants used in this study were Averrhoa bilimbi and Averrhoa carambola. The latex used was 150 ml of PB 260 clone rubber with a concentration of 100% natural coagulant of 75 ml and 2% formic acid. The rubber properties that were tested were Po, PRI, DRC, ash content, dirt content, volatile matter content and Mooney viscosity. This research also uses a special treatment in the form of centrifugation speed. The higher the centrifugation speed, the higher the pH value of the natural coagulant and the lower the H+ ion value, which accelerates the coagulation time of the latex. In natural coagulant extract, the highest values of Po, PRI, DRC, ash content, dirt content and Mooney viscosity were obtained at 0 rpm for Averrhoa bilimbi extract with values of 40%, 94.17%, 32.83%, 0, 32%, 0.038% and 77 MU. Meanwhile, in the test for volatile matter content, the highest value was found in Averrhoa carambola at 5000 rpm with a value of 0.23%.

Abstract

This study investigates the optimization of ensiling time for fermenting Kepok/Saba banana peel into silage for ruminant nutrition. Two ensiling durations were compared: T1 with a 7-day ensiling time and T2 with a 14-day ensiling time. The results of the experiment reveal that while T2 demonstrated certain advantages, such as enhanced aroma and texture due to extended fermentation, the physical quality of silage from T1 was comparable, and the proximate analysis indicated no significant difference in nutritional content between T1 and T2. Additionally, T1 silage exhibited a lower crude fiber content compared to T2, suggesting potentially better digestibility and nutrient availability for livestock. These findings emphasize the practicality of choosing T1 to expedite production without compromising physical quality or nutritional integrity. The study underscores the potential of Kepok/Saba banana peel waste to be processed into silage, offering a sustainable solution for utilizing Lampung’s agricultural by-products for ruminant nutrition enhancement.

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

Tujuan penelitian ini adalah memahami pengaruh koagulan alami pada karakteristik karet SIR 20. Koagulan alami yang digunakan yaitu mangga kweni, asam gelugur, manggis, ciplukan, dan rambutan, karena bersifat asam dan banyak ketersediaannya. Koagulan alami diekstrak dan selanjutnya langsung digunakan sebagai koagulan, namun ekstrak ini juga dilakukan sentrifugasi untuk mendapatkan ekstrak yang lebih bersih. Koagulan kimia yang digunakan sebagai pembanding adalah asam formiat dengan konsentrasi 2%. Volume koagulan sentrifugasi dan tanpa sentrifugasi yang digunakan adalah 75 ml dicampur dengan 150 ml lateks, sehingga terjadinya proses koagulasi dan menghasilkan koagulum. Koagulum dikarakterisasi sesuai mutu SIR 20 dalam SNI 1993:2017 meliputi parameter Po, PRI, viskositas mooney, kadar abu, kadar pengotor, kadar zat menguap, dan kadar nitrogen. Pengaruh karakteristik karet dengan koagulan alami tanpa sentrifugasi menghasilkan nilai Po tertinggi dari ciplukan sebesar 44, PRI tertinggi dari manggis sebesar 75%, viskositas mooney tertinggi dari manggis, ciplukan, dan rambutan sebesar 81 MU, kadar zat menguap terendah dari mangga kweni sebesar 0,31% dan kadar nitrogen dari ciplukan sebesar 0,02%. Sedangkan kadar abu dan kadar kotoran terendah dihasilkan dari koagulan alami sentrifugasi dengan kadar abu terendah dari rambutan sebesar 0,192% dan kadar kotoran terendah pada mangga kweni sebesar 0,20%. Penggunaan koagulan alami sebagai koagulan lateks menghasilkan mutu karet yang lebih baik dibandingkan dengan koagulan kimia asam formiat 2%, tetapi penggunaan koagulan alami menghasilkan kandungan nitrogen yang tinggi. Koagulan alami dengan sentrifugasi dan tanpa sentrifugasi pada asam gelugur, ciplukan, rambutan yang digunakan telah memenuhi persyaratan SNI 06-1903-2017 SIR 20.

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.
