Abstract

SOCIALIZATION OF COVID-19 AND PRACTICE OF MAKING DISINFECTANT LIQUIDS FOR FLOOR MOP MATERIALS IN ISLAMIC MODERN BOARDING SCHOOL OF DARUSALAM, KEPAHIANG REGENCY, BENGKULU PROVINCE. Floor cleaner liquid is a disinfectant used to prevent the transmission of environmental pathogenic microorganisms, especially on the floors. The high price of floor cleaner in the market and difficult to find in the condition of the current Covid-19 outbreak, make this community service activity need to be done and it aims to overcome this problem by holding out socialization about Covid-19 and the practice of making disenfectant fluids as floor cleaning materials at the Islamic Modern Boarding School of Darussalam, Kepahiang Regency. It is expected, by this activity can create a small business to manufacture floor mop from disinfectant with good management in this school. Community Service Activities (PPM) were well received by the students and the teaching staff of the Islamic Modern Boarding School of Darussalam. Before giving service materials to community service participants, the participants or students did not really know what was the cause and prevention of Covid-19 in the surrounding environment and how to make disinfectants. The giving of the pre-test stage questionnaire after the end of the socialization was considered as feedback for participants resulting in an increase in understanding of Covid-19, increasing awareness of the importance of maintaining clean floors and understanding of how to make disinfectant fluids as floor mops made from sodium hypochlorite.

Abstract

AbstrakFosfor merupakan salah satu unsur makro nutrien yang dibutuhkan untuk perkembangan tumbuhan dan dapat dihasilkan oleh bakteri pelarut fosfat. Namun, keberadaan fosfat dalam tumbuhan tidak dapat digunakan oleh tumbuhan itu sendiri, sehingga dibutuhkan bantuan bakteri endofit yang berperan sebagai agen pemacu pertumbuhan tanaman yang dapat melarutkan fosfat pada tumbuhan, khususnya tumbuhan akar kuning (Arcangelisia flava (L.) Merr) yang tumbuh liar di Pulau Enggano, Provinsi Bengkulu. Tujuan penelitian ini untuk memperoleh bakteri endofit yang dapat melarutkan fosfat. Isolasi dilakukan dengan metode sterilisasi permukaan, menggunakan alkohol 70% dan natrium hipoklorit 5,25% lalu ditempelkan di media NA. Isolat yang diperoleh kemudian diuji kemampuan melarutkan fosfat dengan digoreskan ke media Pikovskaya, lalu diukur zona bening. Hasil penelitian menunjukkan dari 18 isolat bakteri endofit, 8 di antaranya dapat melarutkan fosfat. Isolat AKE15 dan AKE18 memiliki kemampuan lebih tinggi untuk melarutkan fosfat dengan indeks pelarut fosfat (IP) ± 1,59 dan ± 1,01. Identifikasi berdasarkan pewarnaan Gram dan uji biokimia dari 8 isolat bakteri endofit pelarut fosfat (BPF) memiliki kedekatan dengan 4 genus, yaitu Bacillus, Micrococcus, Pseudomonas, dan Morococcus.AbstrakPhosphorus is one of the macronutrients required for plant development and produced by phosphate solubilizing bacteria. However, plants are unable to utilize phosphate themselves, thus they need the help of endophytic bacteria that play role as plant growth-promoting with ability to solubilize phosphates in plants, particularly in yellow root plants (Arcangelisia flava (L.) Merr) that grow wildly in Enggano Island, Bengkulu Province. The research aimed to obtain endophytic bacteria that can solubilize phosphate. Isolation of endophytic bacteria was carried out by surface sterilization method using 70% alcohol and 5.25% sodium hypochlorite to be further placed on Nutrient Agar (NA) media. The isolates obtained were further tested for their ability to solubilize phosphate by streaking the isolate on Pikovskaya media and measuring the clear zones formed. The results showed that 8 out of 18 endophytic bacterial isolates were able to solubilize phosphate. Endophytic isolates of AKE15 and AKE18 were found to have higher ability to solubilize phosphate with a phosphate solubilizing index (IP) of about ± 1.59 and ± 1.01, respectively. Identification based on Gram staining and biochemical tests indicated that 8 endophytic bacterial solubilizing isolates were closely related to 4 genera, namely Bacillus, Micrococcus, Pseudomonas, and Morococcus.

Abstract

Information about the introduction and how to identify the macrofungi in the Madrasah Aliyah Al-Hasanah is still low, so it is necessary to introduce methods for dealing with macrofungi. Identification of macrofungi is one of the methods used to determine the macrofungi, whether they are pathogenic or not by looking at the morphological characteristics of the macrofungi. The activity of community service began with licensing by the Madrasah, providing material about macrofungi, the community service team shows some examples of wet herbariums for several previously identified macrofungi. After studying the macrofungi technique, the community service team and students developed skills in finding macrofungi from several wet herbariums that had been provided by the community service team, and formed study groups for participants to better understand the introduction and how to identify macrofungi. In this community service, it is hoped that the participants can develop skills in finding, discovering, identifying and preserving of the macrofungi and become apart of learning material for teachers and students. Macrofungi can also be used as medicine in the health sectors, as an environmental decomposer and useful in the economic field because they can be used as food ingredients.

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

Barumanis Village, located in Bermani Ulu District, Rejang Lebong Regency, Bengkulu Province, has considerable horticultural agricultural potential, particularly in the production of fruits and vegetables. Intensive agricultural activities generate large amounts of organic waste that have not been optimally managed, leading to environmental pollution, unpleasant odors, and the proliferation of disease vectors. One environmentally friendly and economically valuable alternative for managing organic waste is the cultivation of Black Soldier Fly (BSF) larvae (Hermetia illucens). This community service program aimed to enhance the knowledge and practical skills of local residents in utilizing organic waste as a substrate for BSF larvae cultivation, thereby supporting the development of community-based creative economic activities. The program was implemented in three stages: (1) educational outreach on the characteristics, benefits, and cultivation techniques of BSF larvae; (2) demonstrations and hands-on training in organic waste management and BSF cultivation; and (3) evaluation and monitoring using pre-test and post-test instruments. The results demonstrated a significant improvement in participants' understanding of the benefits of BSF larvae, cultivation techniques, and their potential application as a sustainable solution for organic waste management and an alternative source of household income. Evaluation results indicated that participants who initially had limited knowledge of BSF cultivation showed marked improvement, as reflected by higher post-test scores compared to pre-test scores. This program is expected to encourage the implementation of sustainable organic waste management practices while improving community welfare through the development of BSF cultivation enterprises based on local resources.
