Kayeli Bay is a water in Buru Regency which has very important value in terms of ecological and economic functions. During its development, the ecosystem in Kayeli Bay bears the burden of pollution, especially heavy metal mercury as a result of the people's gold mining on Buru Island which uses Hg to get pure gold. Hg can accumulate in the environment, especially deposited in the sediments in Kayeli Bay waters. Mangrove plants that generally grow in estuary and coastal environments are a place for sediment accumulation. This plant has the ability to absorb and accumulate heavy metals, one of which is R. mucronata. This study aims to analyze the concentration of heavy metal Hg in mangroves of R. mucronata and sediments, and to analyze the bioaccumulation of heavy metal Hg in R. mucronata in Kayeli Bay, Buru Regency. Samples were taken from 3 stations, namely the Anahoni River Estuary (Station I), the Wailata River Estuary (II Station) and the Waeapo River Estuary (III Station). Each station has 2 sampling points (replicates). Determination of the concentration of Hg metal in the sample using the CV-AAS method. The average value of Hg concentration in the roots was higher than the bark and leaves of the mangrove R. mucronata, but the concentration was lower than the sediment and was still below the critical value of Hg for plants. The average value of sediment Hg concentration is still below the sediment quality standard. In this study, R. mucronata mangroves were excluder and phytostabilized, where there was a limitation on the absorption of heavy metal Hg from water and sediment and the most Hg accumulation was found in the roots.

Background: Illegal gold mining in Buru Regency uses the heavy metal mercury toprocess gold material, so it can pollute the environment, including aquatic biota such asmangrove crabs (Scylla serrata) and mangrove snails (Telescopium telescopium). The aimof this research is to analyze the amount of mercury concentration and the level of pollutionin mangrove crabs and snails as a result of illegal gold mining in Buru Regency.Methods: Research samples were taken at the Waelata River Estuary and the AnahoniRiver Estuary. For mercury analysis, 8 mangrove crabs and 16 mangrove snails weretaken. Analysis of mercury concentration using the AAS Cold Vapor method.Results: The results showed that the heavy metal mercury was detected in mangrovecrabs and mangrove snails. The concentration of mercury detected is still below the qualitystandard set based on heavy metal contamination (SNI) No. 7387 of 2009, specifically forthe heavy metal Hg in shellfish (bilvalves), mollusks and sea cucumbers, shrimp and othercrustaceans at 1.0 mg/kg (ppm).Conclusion: Illegal gold mining in Buru Regency has an impact on mercury concentrationsin mangrove crabs and mangrove snails, but the value is still below the specified qualitystandards. However, consumption of mangrove crabs and mangrove snails that live aroundgold mining areas in Buru Regency must be limited, considering the nature of mercuryaccumulation.

The study was conducted from August to September 2024 at the seaweed cultivation location in Kaiely Bay, with sampling at three observation stations. The method used was a survey with a laboratory approach. The parameters analyzed included phytoplankton abundance, chlorophyll-a content, and identification of pests and diseases in seaweed. The data obtained were analyzed descriptively. The results of the study showed that the abundance of phytoplankton at the three research stations was very high (eutrophic) with the highest value at Station 2 (8,133,333.33 cells/L) and the lowest at Station 3 (6,043,333.33 cells/L). Chlorophyll-a at all stations was in the eutrophic category with the highest concentration at Station 2 (0.00137 mg/L). The types of pests found at all stations were chicken fish, rabbitfish, and turtles. There were two types of bacteria found, namely station 1 pathogenic bacteria Pseudomonas aeruginosa, station 2 and station 3 types of Vibrio. Thallus morphology at station 1 was: gouging and stripping, station 2 was stripping, tip-nipping and ice-ice and station 3 was gouging, stripping, tip-nipping, and ice-ice.

Mercury is a neurotoxic heavy metal with high bioaccumulation ability in aquatic biota, such as mangrove crabs (Scylla serrata), mangrove snails (Telescopium telescopium), and mangrove mussels (Polymesoda erosa), which are widely consumed by humans, and used as bioindicators of pollution. This study aimed to analyze the effect of mercury solution concentration and species differences on mercury absorption in the three biota. The method used was experimental treatment with mercury concentrations of 1 ppm, 5 ppm, 10 ppm, and control. Samples were analyzed using the AAS Cold Vapor method at the IPB Bogor Proling Laboratory. Data were analyzed descriptively and inferentially using two-way Anova with an α level of 0.05, followed by the Duncan Test if the hypothesis was accepted. Research data will be processed using SPSS 26.0 software. The results showed that mercury concentration and species differences influenced the ability to absorb mercury. Mangrove clams had the highest mercury accumulation compared to mangrove snails and mangrove crabs, especially in the 5 ppm and 10 ppm treatments. The highest mercury exposure occurred on the second day of observation.

The clove leaves are part of the clove plant which rarely used, and if you look at them, the clove leaves have active compounds that can be functioned as antibacterials. Meanwhile, Virgin Coconut Oil or called VCO, is processed from coconut milk as the essential ingredient, and if it is not processed correctly, VCO will usually have a short shelf life or can be damaged quickly. This study aims to determine the quality of VCO by adding clove leaves in its processing. Based on the results of the study, it can be seen that the quality of VCO with the addition of clove leaves for the indicator of water content and the free fatty acid number is not following the Indonesian National Standard (SNI). In contrast, the indicator for the VCO peroxide number with a mixture of clove leaves has good quality according to the SNI standard. Based on the results of the study, it can be seen that the quality of VCO with the addition of 100 grams of clove leaves for indicators of water content and fatty acid numbers, namely 2.9% and 0.69%, is high or above the SNI standard limit. In comparison, the quality of VCO with the addition of 100 grams of clove leaves with indicators a peroxide value of 0.7 mg ek/ kg or less than 2 mg ek/kg has good quality based on Indonesian National Standard. Keywords: Quality, VCO

Pada awal tahun 2020, dunia digemparkan dengan penyakit covid-19 yang disebabkan oleh virus corona, pemerintah menghimbau untuk menerapkan perilaku 3M yaitu menjaga jarak, menggunakan masker dan mencuci tangan. Salah satu alternative untuk mencuci tangan yaitu dengan menggunakan hand sanitizer. Umumnya dalam pembuatan hand sanitizer dapat menggunakan berbagai jenis tanaman yang memiliki kandungan zat aktif dan memiliki potensi dalam menghambat pertumbuhan bakteri yaitu senyawa minyak atsiri, saponin, dan flavonoid. Salah satu contoh tanamannya yaitu daun kayu putih. Penelitian ini memiliki tujuan yaitu untuk mengetahui efektifitas dari hand sanitizer ekstrak daun kayu putih sebanyak 60% dalam menghambat bakteri Staphylococcus aureus. Penelitian ini menggunakan metode sumuran dalam menentukan zona bening sebagai indicator dari efektifitas hand sanitizer. Hasil penelitian menunjukan bahwa hand sanitizer dengan bahan ekstrak daun kayu putih sebanyak 60% memiliki zona bening sebesar 10 mm dan memilliki daya hambat yang tergolong Sedang, bila dibandingkan dengan perlakuan kontrol positif yaitu Amoxilin sebesar 2 mm dan kontrol positif berupa hand sanitizer antis sebesar 0 mm. kesimpulan dari enelitian ini yaitu pembuatan hand sanitizer dengan tambahan ekstrak daun kayu putih sebanyak 60% cukup efektif dalam menghambat pertubuhan bakteri Staphylococcus aureus

This study aims to analyze the quality of the waters of the Anahoni river due to gold mining by covering physical and biological parameters. Physical parameters include color, temperature and TSS (Total Suspended Solids). In the results of measuring the color of the waters of the Anahoni River and Waelata River at all research stations, it ranges from 1 - 5 NTU, which is still below the maximum limit. The results of the water temperature values at the research stations varied between 26.4 – 34.40C. The measured water TSS value at all research stations ranged from 0.011 - 0.018 indicating that the TSS value was below the quality standard value. Biological parameters using coliform bacteria. The results of using fecal coliform bacteria varied at each research station with a range of 0 – 68 MPN/100 mL
