Abstract

Background: The peppermint plant (Mentha piperita L.) is a type of medicinal plant that is widely found in temperate regions, especially Europe, North America and Africa. This plant contains essential oils, menthol, and menthone, menthafuran, sesquiterpenes, triterpenes, flavonoids, carotenoids, tannins and various minerals are also widely contained in peppermint leaf oil (M. piperita L.). The purpose of this study was to isolate and determine the morphological diversity of endophytic bacteria from peppermint plants (M. piperita L.). Methodology: The method used in this study is to take isolation samples, pure culture, characterization and gram staining to determine whether it includes gram-negative or positive bacteria. The results of the study of 12 cultures of endophytic bacterial isolates from plants (M. piperita L.) were taken 10 isolates from each different culture media. Findings: The results of morphological observations of bacterial colonies show diverse characteristics in terms of surface, appearan, ceelevation, edges, and colour. Gram Staining Test of Endophytic Bacterial Isolates from the roots, leaves, and stems of mint plants against endophytic bacteria showed that there were gram-positive and gram-negative bacterial isolates. Then the results of bacterial cell shape morphology have a diversity of Cocobacil, Coccus, and Bacil forms so it can be concluded that endophytic bacterial isolates from peppermint plants (M. piperita L.) have varied morphological diversity. Contribution: Data on the morphological diversity of endophytic bacteria from M. piperita L. provides important basic data for further research on the potential of M. piperita L. endophytic bacteria

Abstract

Ikan fillet tuna merupakan pengolahan inovasi ikan yang memiliki daya simpan yang singkat jika disimpan dalam suhu ruang. Penelitian ini bertujuan untuk memperpanjang daya simpan dan mempertahankan mutu fisik ikan fillet tuna dalam suhu ruangan dengan menggunakan lapisan kitosan. Penelitian ini menggunakan metode edible coating dengan merendam ikan fillet tuna pada larutan kitosan dengan berbagai variasi yakni tanpa perlakukan sebagai kontrol negatif, berbagai konsentrasi kitosan dari 1%, 1,5%, 2%, 2,5%, 3%, serta penggunaan formalin dengan konsentrasi 1% dan 10% sebagai kontrol positif selama 5 menit. Hasil menunjukkan bahwa ikan fillet tuna dengan konsentrasi 3% dapat memperpanjang daya simpan selama 4 hari sedangkan tanpa perlakuan sebagai kontrol negatif bertahan selama 2 hari, sampel dengan konsentrasi 1%, 1,5%, 2%, dan 2,5% memperpanjang daya simpan selama 3 hari. Maka dapat disimpulkan penggunaan larutan kitosan dapat digunakan sebagai pengawet ikan fillet tuna serta mempertahankan parameter fisik (tekstur, warna, aroma) dan pH ikan fillet tuna lebih baik setelah perlakukan dibandingkan sebelum perlakuan dengan larutan kitosan.

Abstract

Hand is the main transmission pathogen entry into the body which is the part of the body that is most often in direct contact with other limbs and surrounding objects. The importance of maintaining hand hygiene by always washing hands with soap is the first step in preventing transmission of COVID-19. However, during a pandemic like this, it will be difficult to find soap available everywhere, and tends to be hard to carry all the time. Therefore, this service aims to invite the people of Pematang Gubernur, Bengkulu City, to use paper soap because it is easier to use its use and flexible to carry anywhere besides being an effort to prevent the COVID-19 outbreak, it can also add to new information and skills for residents in making attractive soaps. The feedback response given by the community service implementation team to the community service participants resulted in a positive response to this activity, who initially did not know about making and use of paper soap and became aware of this.
