Abstract

The digestive system of sea urchins functions to process organic material from food into bioactive compounds. . However, the direct exploitation of bioactive compounds from sea urchins may trigger ecological imbalances. These bioactive compounds can also be produced through interactions between sea urchins and their diverse associated bacteria within the body. Therefore, alternative methods are needed to obtain bioactive compounds without disrupting the aquatic ecosystem. This study aims to explore bioactive compounds from the associated bacteria of sea urchins (Stomopneustes variolaris Lamarck and Tripneustes ventricosus Lamarck) originating from Kaur Regency, Bengkulu. A total of 30 bacterial isolates were successfully obtained using Zobell Marine Agar (ZMA) medium. Potential isolates were identified through morphological observation, Gram staining, and biochemical tests. Antibacterial activity assays showed that 12 isolates had potential as antibacterial producers based on tests against Bacillus subtilis, Escherichia coli, and Staphylococcus aureus. Two isolates, TVL 6 and TVL 11, were able to inhibit all test bacteria. Additionally, assays using pellets and supernatants showed that all 12 isolates exhibited antibacterial activity, with 5 isolates showing activity in the supernatant. Isolates TVL 6 and TVL 11 were proven effective in inhibiting all test bacteria in both pellet and supernatant forms, with the highest inhibition observed against Staphylococcus aureus. These results indicate that the associated bacteria in the digestive tract of sea urchins have potential as candidates for antibacterial compound producers.   Sistem pencernaan bulu babi berfungsi untuk mengolah bahan organik dari makanan menjadi senyawa bioaktif. Namun, eksploitasi senyawa bioaktif dari bulu babi secara langsung dapat memicu ketidakseimbangan ekosistem. Senyawa bioaktif ini juga dapat dihasilkan melalui interaksi antara bulu babi dengan bakteri asosiasi yang beragam di dalam tubuhnya. Oleh karena itu, diperlukan metode alternatif untuk memperoleh senyawa bioaktif tanpa merusak keseimbangan ekosistem perairan. Penelitian ini bertujuan untuk mengeksplorasi senyawa bioaktif dari bakteri asosiasi bulu babi (Stomopneustes variolaris Lamarck dan Tripneustes ventricosus Lamarck) asal Kabupaten Kaur, Bengkulu. Sebanyak 30 isolat bakteri berhasil diisolasi menggunakan media Zobell Marine Agar (ZMA). Identifikasi isolat potensial dilakukan melalui pengamatan morfologi, pewarnaan Gram, dan uji biokimia. Uji aktivitas antibakteri menunjukkan bahwa 12 isolat memiliki potensi sebagai penghasil antibakteri berdasarkan pengujian terhadap kultur uji Bacillus subtilis, Escherichia coli, dan Staphylococcus aureus. Dua isolat, TVL 6 dan TVL 11, mampu menghambat semua bakteri uji tersebut. Selain itu, pengujian menggunakan pelet dan supernatan menunjukkan bahwa 12 isolat mampu menghasilkan aktivitas antibakteri, dengan 5 isolat menunjukkan aktivitas pada supernatan. Isolat TVL 6 dan TVL 11 terbukti efektif menghambat semua bakteri uji baik pada pelet maupun supernatan, dengan penghambatan tertinggi terhadap Stapylococcus aureus. Hasil ini mengindikasikan bahwa bakteri asosiasi dalam saluran cerna bulu babi memiliki potensi sebagai kandidat penghasil antibakteri.

Abstract

The bark of the traditional plant, Archidendron bubalinum, known locally as kabau, exhibits promising qualities as a natural antibacterial agent. This research was conducted with two main objectives: (1) to evaluate the antibacterial efficacy of kabau fruit peel extract against two common pathogenic bacteria, Staphylococcus aureus and Escherichia coli, and (2) to design, validate, and assess the effectiveness of a research-based Microbiology E-Module in fostering students' critical analytical skills. The antibacterial capacity was tested using the paper disc diffusion method across a range of extract concentrations (5%, 10%, 20%, 40%, and 80%), using both pure water (aquades) and 2% dimethyl sulfoxide as carriers. Statistical analysis (one-way ANOVA, p = 0.020 < 0.05) indicated a notable difference in the zone of inhibition diameter across the various concentrations. The most potent antibacterial effect was observed at the 80% concentration with the aquades solvent, yielding inhibition zones of 3.97 mm against S. aureus and 8.42 mm against E. coli. These empirical results served as the core content for the innovative E-Module. The developed E-Module attained a high level of validity, achieving a CVR score of 1.00 from 5 expert validators, thus confirming its readiness for use. Subsequent evaluation during instructional application revealed a marked elevation in students' critical thinking abilities. Students in the Biology Department at FMIPA, Universitas Bengkulu, showed an initial mean pre-test score of 41.67, which surged to 88.00 in the post-test. This change resulted in an N-gain score of 0.79, positioning the improvement in the "high" category. Therefore, A. bubalinum extract is confirmed to hold antibacterial potential, and the E-Module is proven to be an effective educational tool for enhancing students' critical thinking competence.

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

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.
