Abstract

Trans Malakoni Village, located on Enggano Island, Bengkulu Province, faces significant challenges in providing access to clean, potable water. Limited access to adequate freshwater sources and water quality that frequently fails to meet health standards are major obstacles to the community's sustainable livelihood. This research aims to explore the potential and implementation of household-scale reverse osmosis (RO) technology as an innovative solution for producing clean, potable water in Trans Malakoni Village. The research methodology involves raw water quality analysis, the design of a household-scale RO system suitable for local conditions, and an evaluation of system performance and community acceptance. Initial results indicate that existing water sources in Trans Malakoni Village, although limited, can be effectively treated using RO technology to achieve established drinking water quality standards. The proposed household-scale RO system design emphasizes energy efficiency, operational ease, and affordable maintenance costs, thereby enabling sustainable adoption by households. The implementation of RO technology is expected not only to enhance access to clean water but also to contribute to improved public health, self-reliance in water resource management, and sustainable living in Malakoni Village. This study recommends further research on system optimization and community education programs to maximize the positive impact of RO technology in other remote island regions.

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.

Abstract

This study aims to inventory the types of food crops growing around tailings ponds and to quantify mercury concentrations in food crop tissues growing in the area around the gold mine. The samples taken are plants consumed by residents. Mercury content testing uses a mercury analyzer. The results of the study showed that from 4 observation locations, a total of 11 types of food crops were found, all of which contained mercury (Hg) with a concentration range of 0.01-0.54 mg/kg. Similarly, the soil as a growing medium contains quite high levels of mercury at location 1, namely 54.36 mg/kg, and the lowest at location 3 at 0.12 mg/kg. The concentration of mercury in vegetable leaves is much higher than in other organs such as tubers, flowers, and fruits. Furthermore, to plant plants for consumption, it is best to pay attention to the condition of the growing medium, as a prevention of heavy metal (mercury) contamination, such as the environment (air, soil, water) that is far from waste retention ponds or waste discharge streams containing heavy metals (mercury). Analisis Konsentrasi Merkuri pada Tanaman Pangan di Sekitar Tambang Emas Kabupaten Lebong ABSTRAK: Penelitian ini bertujuan untuk menginventarisasi jenis tanaman pangan yang tumbuh disekitar kolam penampungan limbah (tailing) dan untuk mengkuantifikasi konsentrasi merkuri dalam jaringan tanaman pangan yang tumbuh di area sekitar tambang emas. Sampel yang diambil merupakan tanaman yang memang dikonsumsi oleh warga setempat. Uji kandungan merkuri menggunakan mercury analyzer. Hasil penelitian menunjukkan dari 4 lokasi pengamatan, ditemukkan Sebanyak 11 jenis tanaman pangan yang semuanya mengandung merkuri (Hg) dengan kisaran konsentrasi 0,01-0,11 mg/kg. Demikian pula, tanah sebagai media tanam mengandung kadar merkuri yang cukup tinggi di lokasi 1, yaitu 54,36 mg/kg, dan paling rendah dilokasi 3 sebesar 0,12 mg/kg. konsentrasi merkuri dalam daun sayuran jauh lebih tinggi dibandingkan organ lain seperti tuber, bunga, dan buah. Selanjutnya, untuk menanam tanaman yang akan dikonsumsi sebaiknya memperhatikan kondisi media tumbuh, sebagai pencegahan dari kontaminasi logam berat (merkuri), seperti lingkungan (udara, tanah,air) yang jauh dari kolam penampungan limbah maupun aliran pembuangan limbah yang mengandung merkuri.

Abstract

The increasing intensification of dragon fruit (Hylocereus sp.) cultivation is followed by an increase in disease attacks that have the potential to reduce plant productivity. This study aims to isolate, identify, and test the pathogenicity of bacteria that cause dragon fruit stem rot in Pematang Donok Village, Kepahiang, Bengkulu. Bacterial isolation was carried out from disease-infected stem tissue, followed by isolation purification. Bacterial identification was carried out based on colony morphology and Gram staining, while pathogenicity and hemolysis tests were carried out on potatoes and blood agar media, respectively. The data were analyzed descriptively qualitatively through observation of colony morphological characteristics and Gram staining, as well as pathogenicity tests on potatoes and hemolysis tests on blood agar. The isolation results obtained two bacterial isolates, namely isolates BBNK1 and BBNK2 with different colony morphology characteristics. Both isolates are Gram-positive bacteria with bacillus and coccus cell shapes. Pathogenicity tests on potatoes showed that both isolates were able to cause soft rot symptoms such as tissue softening, discoloration, and mucus formation compared to the control. Hemolysis tests showed that only isolate BBNK1 showed hemolytic activity with the formation of a clear zone around the isolate. The findings of this study offer foundational data to support future research on molecular identification and the development of more environmentally friendly and sustainable disease management strategies.

Abstract

Abstract: Chitinolytic actinobacteria are currently more widely used because of their ability as the biological control agents to the pathogenic fungi, especially in horticultural and plantation crops. This research was conducted to obtain isolates of chitinolytic soil actinobacteria from the rhizosphere of the rubber plant (Hevea brasiliensis) area in IPB University. Antifungal activities from these actinobacteria hopely able to inhibit the growth of plant pathogenic fungi in Vitro on chitin agar media. Fusarium oxysporum and Sclerotium rolfsii are used in the inhibition test of chitinolytic actinobacteria. The results successfully obtained 16 isolates of actinobacteria were grew on  Humic Acid Vitamin (HV) agar. It showed that six of 16 actinobacteria isolates were able to produce inhibition zones to the growth of hyphae of pathogenic fungi on potato dextrose agar (PDA). KK-15 and KK-07 isolates were able to produce the largest inhibition percentages in F. oxysporum and S. rolfsii. Based on the chitinolytic index (CI) values, KK-15 and KK-07 isolates produced CI values of 1.25 and 1.5, respectively. The morphological characteristics and Gram staining of both KK-15 and KK-07 isolates are closely relative with Streptomyces sp. Abstrak: Bakteri kitinolitik saat ini banyak diteliti karena kemampuannya sebagai agens pengendali hayati jamur patogen khususnya pada tanaman hortikultura dan perkebunan.

Abstract

Penyakit menular seperti demam tifoid yang disebabkan oleh bakteri Salmonella typhi masih menjadi masalah kesehatan utama karena meningkatnya kasus resistensi antibiotik. Penelitian ini bertujuan untuk mengetahui dan menganalisis potensi aktivitas antibakteri ekstrak etanol 96% daun ciplukan (Physalis angulata L.) terhadap pertumbuhan bakteri Salmonella typhii. Metode penelitian yang digunakan adalah eksperimental laboratorium dengan pengujian aktivitas antibakteri menggunakan metode difusi cakram. Sampel daun ciplukan diekstraksi dengan metode maserasi menggunakan pelarut etanol 96%. Konsentrasi ekstrak yang diuji bervariasi antara 5%, 25%, 50%, 75%, dan 100%, dengan kloramfenikol sebagai kontrol positif dan DMSO sebagai kontrol negatif. Hasil skrining fitokimia menunjukkan bahwa ekstrak etanol daun ciplukan mengandung senyawa metabolit sekunder berupa flavonoid, alkaloid, fenol, tanin, dan steroid/triterpenoid. Hasil uji aktivitas antibakteri menunjukkan bahwa seluruh konsentrasi ekstrak memiliki daya hambat terhadap Salmonella typhii. Konsentrasi 5% menghasilkan rata-rata zona hambat sebesar 2,02 mm (kategori lemah), sedangkan konsentrasi 25% menghasilkan rata-rata zona hambat sebesar 4,82 mm (kategori lemah), konsentrasi 50%, 75%, dan 100% menghasilkan zona hambat masing-masing sebesar 6,32 mm, 6,20 mm, dan 6,77 mm yang termasuk dalam kategori sedang. Diameter zona hambat cenderung meningkat seiring dengan bertambahnya konsentrasi ekstrak. Penelitian ini dapat disimpulkan bahwa, ekstrak etanol daun ciplukan memiliki aktivitas antibakteri terhadap Salmonella typhii, namun efektivitasnya masih lebih rendah dibandingkan kontrol positif kloramfenikol.

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

Background: Candidiasis is an opportunistic fungal infection caused by Candida albicans, particularly affecting immunocompromised individuals. Increasing antifungal resistance has encouraged the search for natural anticandidal agents, including sea urchin gut symbiotic bacteria. Information regarding the anticandidal activity of gut symbiotic from Stomopneustes variolaris and Tripneustes ventricosus remains limited. This study evaluated the anticandidal potential of gut symbiotic bacterial isolates from these sea urchins collected from Laguna Beach and Pengubaian Beach, Kaur Regency, Bengkulu. Methodology: Six bacterial isolates, TVL 6, TVL 11, TVL 13, SVP 1, SVP 6, and SVP 15 were subcultured on Zobell Marine Agar (ZMA) and tested against C. albicans. Anticandida activity was evaluated using the spot inoculation method for bacterial cultures and the disk diffusion method for bacterial pellets. Nystatin and sterile distilled water served as positive and negative controls, with all assays performed in triplicate. Inhibition zones were measured using a digital caliper. Findings: All isolates inhibited the growth of C. albicans. In the culture assay, isolate TVL 6 showed the highest inhibition zone diameter of 11.58 mm, while SVP 1 showed the lowest activity (8.08 mm). In the pellet assay, TVL 11 exhibited the highest activity (16.65 mm), whereas SVP 15 showed the lowest activity (5.50 mm). Overall, pellet preparations produced larger inhibition zones than culture preparations. Contributions: Gut symbiotic bacteria from sea urchins collected in Kaur Regency, Bengkulu, showed promising anticandidal activity against C. albicans, supporting their potential as marine-derived sources of alternative anticandidal against and providing a basis for future studies on isolate identification, bioactive metabolites, and mechanisms of action.

Abstract

Abstract: Mangroves Rhizophora stylosa Griff. and Sonneratia alba Sm. produce secondary metabolite compounds that are useful as potential sources of new antimicrobes because they inhibit the growth of pathogenic microbes. Endophytic bacteria are bacteria that live within plant tissues and are capable of producing metabolite compounds with antimicrobial properties. This study aimed to determine the antimicrobial activity and molecular profile of the 16S rRNA gene from endophytic bacterial isolates of R. stylosa Griff. and S. alba Sm. from Enggano Island. The isolates were subcultured on Nutrient Agar (NA) medium. The results showed that five isolates (DRSE 16, DRSE 17, ASAE 3, DSAE 17, and DSAE 19) out of 40 endophytic bacterial isolates exhibited potential activity against the testing microbes (Salmonella typhi, Enterococcus faecalis, and Candida albicans). The results of 16S rRNA identification showed that the bacterial isolate DRSE 16 had similarities with the species Stenotrophomonas nitritireducens strain BR-49, isolate DRSE 17 with the species Pseudomonas putida strain XT214, isolate ASAE 3 with the species Pseudomonas aeruginosa strain D3, isolate DSAE 17 with the species Bacillus subtilis strain C-2-3-2, and isolate DSAE 19 with the species Pseudomonas otitidis strain RR017.
