Abstract

Sea cucumber is a potential fishery sub-sector, but its use still not popular because of its unfavorable physical form. However, from its unfavorable form, sea cucumbers contain many benefits as nutrition and medicine, including the presence of antimicrobial activity. The use of sea cucumbers as a nutrient is used by the people of Ujung Pangkah Gresik village as crackers. This study aims to prove the antimicrobial potential of dried sea cucumbers with crackers from Ujung Pangkah village, Gresik. The sea cucumbers have been boiled first before drying in the sun. The dried sea cucumbers were blended and then extracted using 96% ethanol. The extract was then sterilized by filtration using a 0.2 m PTFE filter. Extracts were tested using the Kirby-Bauer method on Mueller-Hinton Agar medium inoculated with Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhimurium, Burkholderia cepacia, and yeast Candida albicans. The control antibiotic tetracycline 30 µg/ml and antifungal 2,5 µg/ml fluconazole were used as comparisons. The results of this study showed that all ethanolic extracts of dry sea cucumber with concentrations of 5%, 10%, and 15% did not show any clear zone. While the clear zone was shown in the control of tetracycline and fluconazole. This was caused by the loss of antimicrobial activity in the ethanolic extract of dried sea cucumbers derived from antimicrobial peptides which were damaged by heating during boiling process.

Abstract

AbstractOreochromis mossambicus (O. mossambicus) frequently found in the Brantas and Bengawan Solo rivers, Java island, Indonesia. However, heavy metals produced from anthropogenic activities can enter the water and accumulate in organisms living in the river. This study aimed to determine the lead (Pb) heavy metal in the gills, flesh, and intestines of O. mossambicus living in the two aforementioned rivers and to measure the Pb levels in each river. The results showed that the Pb in the O. mossambicus organs in the Bengawan Solo river was as follows 3.159 mg/kg in the gills; 1.930 mg/kg in the intestine; and 2.511 mg/kg in flesh, while in the Brantas river it was follows 1.600 mg/kg in gills; 1.402 mg/kg in the intestine; and 1.455 mg/kg flesh. Pb levels in each river water were 0.568 mg/mL in the Brantas river and 0.525 mg/mL in the Bengawan Solo river. Based on the data obtained, it can be concluded that the Pb content in fish organs and river water has exceeded the quality standard for Pb levels according to the government regulation No.82 2001 (SNI 7387:2009), that is, 0.3 mg/kg in organs and 0.03 mg/L in water. The results of this study are expected to be a concern for the authorities in order to revitalize the river to restore the function and support the survival of river biota.AbstrakIkan mujair (Oreochromis mossambicus) banyak ditemukan di sungai Brantas dan Bengawan Solo, namun aktivitas antropogenik yang menghasilkan logam berat dapat masuk ke perairan sehingga terakumulasi dalam organisme yang hidup di perairan tersebut. Penelitian ini bertujuan untuk mengetahui kandungan logam berat timbal (Pb) pada insang, daging, dan usus pada O. Mossambicus yang hidup di kedua sungai tersebut serta mengukur kandungan Pb pada masing-masing air sungai. Hasil penelitian menunjukkan bahwa kandungan Pb pada organ O. mossambicus di sungai Bengawan Solo adalah sebagai berikut 3.159 mg/kg pada insang; 1.930 mg/kg di usus; dan 2.511 mg/kg pada daging, sedangkan di sungai Brantas adalah sebagai berikut 1.600 mg/kg pada insang; 1,402 mg/kg pada usus; dan 1,455 mg/kg pada daging. Kadar Pb pada masing-masing air sungai adalah 0,568 mg/mL (sungai Brantas) dan 0,525 mg/mL (sungai Bengawan Solo). Berdasarkan data yang diperoleh dapat disimpulkan bahwa kandungan Pb pada organ ikan maupun air sungai sudah melebihi baku mutu kadar Pb pada organ yaitu 0,3 mg/kg (SNI 7387:2009) dan 0,03 mg/L pada perairan (PP No.82 tahun 2001). Hasil penelitian ini diharapkan dapat menjadi perhatian pihak-pihak terkait agar dapat melakukan revitalisasi sungai guna mengembalikan fungsi dan mendukung keberlangsungan hidup biota sungai.

Abstract

The Nusantara Fisheries Port (Pelabuhan Perikanan Nusantara - PPN) in Brondong, Lamongan Regency, is a port with high ship activities. This has led to hydrocarbon pollution in the form of diesel fuel and oil in the waters of PPN Brondong. The initial effort to address this pollution is by isolating and characterizing hydrocarbon-degrading bacteria present in these waters. This research is a strategic step in managing petroleum hydrocarbon spills in the area through bioremediation processes, either via bioaugmentation or biostimulation for further study. The research method involves isolating hydrocarbon-degrading bacteria from the waters of PPN Brondong using the spread plate isolation method. Different colony characteristics are selected for the purification of bacterial isolates. The obtained bacterial isolates are then subjected to hydrocarbon degradation activity by culturing them in a minimal medium containing diesel fuel. The degradation activity is measured using total petroleum hydrocarbon (TPH) testing. The results of this study yielded 7 different isolates from the fuel oil-contaminated sites in PPN Brondong. Culturing in a minimal medium containing diesel fuel yielded results showing that all isolates possess the ability to degrade hydrocarbons, as evidenced by the reduction in TPH.

Abstract

In 2012, Prijekngablak Village, Karanggeneng, Lamongan, faced crop failure due to an uncontrollable pest outbreak. This prompted the Rame Gawe II Farmers' Group to initiate organic farming, despite various social challenges. In 2022, the village government supported these efforts, enabling the community to produce liquid organic fertilizer (POC) and bio-pesticides. However, obstacles such as low public trust, poor institutional coordination, and inadequate laboratory facilities persisted. The Community Service team addressed these issues through focus group discussions (FGDs), facility improvements, laboratory management enhancements, and training on producing and applying POC and bio-pesticides. FGDs revealed that 54.3% of farmers had a strong understanding of organic farming, 62.9% moderately understood its benefits, 51.4% had practical experience, and 77.1% were willing to adopt it. Laboratory improvements and SOP implementation improved production performance. Key products included POC from water hyacinths, bio-pesticides containing Beauveria bassiana and Trichoderma sp., and PGPR isolated from local bamboo roots. Their application enhanced plant health and reduced pest and disease attacks, showcasing the potential of organic farming in overcoming agricultural challenges in the village.

Abstract

The Sawah Tambak Rice-Fish Farming System is a land-use practice that alternates between rice cultivation and fish farming depending on the season. During the dry season, the land is used for growing rice, while in the rainy season, it functions as a fishpond. Successful rice cultivation in this system relies on beneficial rhizosphere bacteria that interact with plant roots through biological, physical, and chemical processes. This study aims to characterize bacteria isolated from the rhizosphere of rice plants (Oryza sativa L.) in this system and evaluate their ability to produce indole-3-acetic acid (IAA) and solubilize phosphate. Bacterial colony identification was performed using the streak plate method, IAA production was measured via spectrophotometry, and phosphate solubilization was assessed using the phosphate solubilization index (PSI). The results showed diverse bacterial isolates with distinct morphological, biochemical, and physiological characteristics. Several isolates exhibited strong IAA production, with B3 reaching the highest concentration (18.29 ppm) on the sixth day. Phosphate-solubilizing bacteria (PSB) were also identified, with B4 and S5 showing the highest PSI values of 6.06 and 5.3, respectively. These findings suggest that rhizosphere bacteria in the Sawah Tambak system have the potential to enhance rice growth by improving phosphorus availability and producing plant growth hormones, contributing to sustainable and environmentally friendly rice cultivation

Abstract

Chikungunya fever (CHIKF) is an infectious disease that has similar symptoms with dengue fever (DF). Several drugs have been offered to treat both dengue (DENV) and chikungunya virus (CHIKV). Investigating anti-CHIKF potential from nearby plants is one strategy to produce potential drug to reduce CHIKF in endemic countries. Physalis peruviana is one the promising object to be new anti-CHIKV drug candidate. This study aimed to analyze the anti-CHIKV agents from leaf parts of P. peruviana. Ligand and protein samples were collected from multiple sources. The phytoconstituents were evaluated their drug-likeness properties throughout SwissADME webservers. Selected ligands then docked via PyRX and measured the output by binding affinity. Visualization of the best outputs was carried out using BIOVIA Discovery Studio. CABS-flex was carried out to screen the RMSF of molecular dynamics activity of the best complex. The result showed that 1,2-benzenecarboxylic acid had the lowest binding affinity following suramin as control with -5.1 and -11.1 kcal/mol after targeting E2 domain protein of CHIKV. This led to the conclusion that 1,2-benzenecarboxylic acid could be forecast as predictive anti-CHIKF therapeutic candidate. Additional in vitro and in vivo studies are needed to validate this outcome.
