Abstract

The leaves of R. stylosa are a potential source of bioactive compounds for health and pharmacology. The composition of bioactive compounds in the leaves can be influenced by the ecological conditions and geographical location of this small island. This study aims to evaluate the toxicity and composition of bioactive compounds that are toxic in mangrove leaf extracts of R. stylosa from Maspari Island in coastal South Sumatra. A total of 1 kg of R. stylosa leaf samples were taken from Maspari Island then washed thoroughly to remove dirt, cut into small pieces, and dried in the sun using the indirect sunlight method covered with black cloth. The dried leaf samples were then pulverized into powder, and as much as 100 grams of fine powder was macerated with 96% ethanol solvent in a ratio of 1:10 (b/v). The maceration process was carried out for 1 x 24 hours, then the maceration solution was filtered and evaporated using a rotary evaporator at 60°C to become a concentrated extract. Toxicity tests were carried out using the Brine Shrimp Lethality Test (BSLT) method, while the identification of toxic bioactive compounds was carried out through phytochemical tests, total phenol tests, and GC-MS analysis. The test results showed that the LC50 value of R. stylosa leaf extract was 393 mg/mL (moderately toxic). The total phenol content was 442.82 (gGA/g), and the bioactive compounds identified included alkaloids, flavonoids, saponins, terpenoids, and acids such as Hexadecanoic acid, methyl ester, and trans-13-Octadecenoic acid, methyl ester.

Abstract

Water quality in the form of turbidity, colour, odour, taste and suspended residue are significant issues in Sungsang Banyuasin. The filter utilizes a filtration method to remove solid particles and contaminants. The research site consists of Sungsang, Sungsang II, and Sungsang III areas. The purpose of this study was to determine the water quality in the form of colour, taste, odour, turbidity, suspended residue, and salinity, as well as the ability of the filter to overcome water quality. Filtration consists of sedimentation, filter membranes, and filter media consisting of zeolite, silica, anthracite, ferrolite, activated carbon, and bioring. Water quality measurements used organoleptic to determine odour and taste, handrefractometer to measure salinity, direct reading to measure suspended residue, and spectrophotometry to measure colour and turbidity. The breech water was odourless and tasteless, and the suspended residue value ranged from 17-19 mg/L below the quality standard of 50 mg/L. Colour and turbidity values are greater than 50 on their respective scales and salinity values range from 11-13 ppt. The filtration process successfully reduced the values of suspended residue, colour, turbidity, and salinity.

Abstract

In coastal environments and the ecosystems, including seagrass ecosystems, heavy metals can lead to pollution. This study goal is to analyze the concentration of heavy metals in water based on safety standards for marine organisms. Water samples were collected from two locations: Jeralangan HamLet and Cukuh Nyai HamLet in Pahawang Island, Lampung, Indonesia. Water quality parameters were measured in situ. Heavy metals such Pb, Cu, Ni, and Zn were prepared using Wet digestion method and the concentrations were measured using Atomic Absorption Spectrophotometer (AAS) SHIMADZU AA-7000. At the same location, the highest concentration of was observed for Zn 0.406 mg/L at station 2, while the lowest concentration was recorded for Cu 0.019 mg/L. The concentration of heavy metals Pb, Cu, Ni and Zn in water has exceeded the quality standards for marine biota and marine tourism.These research can be used as a basis for future planning in the management of Pahawang Island’s coastal environment.

Abstract

Fish and some groups of shrimps and crabs are one of the economically important biota that live in the waters. Accumulation of heavy metals in fish can affect the economic value of marine fishery products. There are several types of fish that contain heavy metals and are harmful when consumed by humans. The purpose of this study was to determine the dominant bycatch fish species and the accumulation of heavy metals Pb and Cu in the bycatch of stationary lift net Pesisir Banyuasin. This study was conducted in November 2019 and the dominant bycatch included japuh fish (Dussumieria acuta), tembang fish (Sardinella fimbriata) and parang-parang fish (Chirocentrus dorab). Samples were taken from one stationary lift net then analysed using SSA (Atomic Absorption Spectrophotometry) with 3 repetitions. The results of the analysis found the average concentration of heavy metals Pb and Cu in japuh fish was 0.65 mg/kg Pb; 0.16 mg/kg Cu. In tembang fish 0.70 mg/kg Pb and 0.03 mg/kg Cu. The parang-parang fish was 0.50 mg/kg and 0.17 mg/kg Cu. Based on the quality standards of SNI, Directorate General of Food and Drug Administration and FAO, the Pb and Cu concentrations of the three types of by-catch fish are still below the quality standard threshold and safe for human consumption.

Abstract

Perubahan luas dan kerapatan mangrove memiliki pengaruh yang besar terhadap keberlangsungan fungsi ekosistem di wilayah pesisir. Penelitian ini bertujuan untuk menganalisis perubahan luas dan kerapatan mangrove di Kota Serang, Banten. Metode yang digunakan adalah penginderaan jauh melalui interpretasi citra Landsat 5 dan Landsat 8 dengan analisis terhadap perubahan luas dan kerapatan mangrove pada tahun 2011 dan 2021. Prosedur penelitian dilakukan dengan mengelompokkan nilai NDVI ke dalam 3 kelas vegetasi, yaitu jarang, sedang, dan rapat. Selanjutnya dilakukan ground check untuk menguji tingkat akurasi data terhadap tutupan kanopi mangrove dengan metode hemisperichal photography. Hasil penelitian menunjukkan bahwa tingkat akurasi citra pada tahun 2021 sebesar 90%. Berdasarkan analisis tersebut diketahui bahwa telah terjadi penurunan luas dan perubahan kerapatan mangrove di Kelurahan Sawah Luhur, sedangkan di Kelurahan Banten justru mengalami peningkatan. Secara umum, di wilayah pesisir Kota Serang terjadi penurunan luas mangrove antara 2011-2021 yang mencapai 13,95 ha dengan penurunan utama terjadi pada mangrove dengan kelas vegetasi jarang (33,14 ha). Sebaliknya, mangrove dengan kategori kerapatan sedang dan rapat justru meningkat hingga 19,19 ha. Penurunan luas mangrove tersebut akibat abrasi alih fungsi menjadi tambak, serta penebangan illegal. Hasil analisis juga menunjukkan bahwa korelasi nilai NDVI dengan persentase tutupan kanopi memiliki nilai 0,696 yang masuk dalam kategori kuat.

Abstract

The distribution of subsidized fuel for fishermen is largely determined by government regulations and policies. A well-implemented distribution institution ensures that subsidized fuel reaches fishermen appropriately. This study aims to analyze the institutionalization of subsidized fuel for fishermen in Kangkung Village, Bumi Waras District, Bandar Lampung City. The approach used is a qualitative approach with a case study method. Data collection through in-depth interviews, participatory observation and documentation studies. Data processing is carried out to analyze the institutionalization of subsidized fuel distribution for fishermen. The results of the study indicate that fishermen who use diesel fuel obtain subsidized diesel fuel at fishermen's fuel station according to the provisions set by the Downstream Regulatory Agency Committee Oil and Fuel. Not all fishermen can meet the required provisions. This causes there are still fishermen who cannot access subsidized diesel fuel for their business needs. Fishermen who use Pertalite also cannot freely access subsidized pertalite at the fuel station due to less supportive institutional governance. Thus, it is still necessary for the government to improve regulations so that distribution is more effective and controlled, so that subsidized fuel can be accessed evenly by small fishermen.

Abstract

The low sustainability of participation in the Fishermen’s Insurance Premium Assistance program shows that there is an Institution issue. The research intents to analyze the institution of the fishermen’s insurance program in Bandar Lampung City. This study used the case study method as a qualitative approach. Data were obtained by in-depth interviews, participant observation, and document analysis. Analysis is used to describe institutions based on situation, structure, behavior, and performance. The results of the study show that the efforts of the insurance program in Bandar Lampung City to protect fishermen have not been achieved in the second year. This occurred because the insurance participants did not pay the premium independently or at personal expense. The fishermen are not interested in participating in insurance, in spite of the premium cost being economical. Institutions are included in the BPAN program, which plays an important role in determining the continuation of fishermen’s insurance participation. The government should consider the punishment and agreements that must be submissive by fishermen to become effective regulation. In addition, the Social Security Administrator for Employment, as an insurance provider, must accommodate the simple insurance premium payments for fishermen.

Abstract

Aeromonas hydrophila, commonly found in aquatic environments, is a Gram-negative bacterium frequently pathogenic to fish, causing diseases such as hemorrhagic septicemia or Motile Aeromonas Septicemia (MAS) in various freshwater fish species. This study investigated the antibacterial potential of red onion skin extract (Allium cepa L.) extracted using 99% absolute alcohol against the growth of Aeromonas hydrophila. The experiments were conducted with varying extract concentrations of 5%, 10%, 15%, 20%, and 25%, using tetracycline as a control. The results demonstrated that the red onion skin extract was able to inhibit the growth of Aeromonas hydrophila, as indicated by the formation of inhibition zones around the growth media. The average diameters of the inhibition zones produced by the extract at concentrations of 5%, 10%, 15%, 20%, and 25% were 1.21 mm, 2.43 mm, 3.36 mm, 5.70 mm, and 6.23 mm, respectively. Statistical analysis using a One-way ANOVA test with SPSS software showed a p-value of 0.000, indicating a significant difference among the red onion skin extract concentrations. Therefore, a Least Significant Difference (LSD) post-hoc test was performed to identify specific differences between the concentration treatments

Abstract

Caulerpa racemosa is one of the green macroalgae that is widely distributed in the coastal areas of Lampung Province and needs to be explored as a phytopharmaceutical ingredient because it is thought to have bioactive compounds. In this study, we also used taurine, which is known to prevent cell and tissue damage due to oxidative processes, to explore its potential as an anticancer. The initial stage of this research is phytochemical screening of 96% ethanol extract of Caulerpa racemosa and contains phenolic compounds . alkaloids, saponins, flavonoids, tannins, steroids and terpenoids. The toxicity test of Caulerpa racemosa ethanol extract and taurine used the BSLT method (Brine Shrimp Lethality Test). In this study, 7 concentrations were used, namely 0 ppm (control); 62.5; 125; 250; 500; 1000; and 2000 for both Caulerpa racemosa and taurine ethanol extracts with 5 repetitions. Meanwhile, the toxicity test results showed that the LC50 value of Caulerpa racemosa ethanol extract was 194.14 ppm and 170.69 ppm for taurine, this values are between 100 ppm - 1000 ppm of Caulerpa racemosa ethanol and taurine indicate that both material have potential anticancer activity with low toxicity.

Abstract

Changes in the area and density of mangroves have a major impact on the sustainability of ecosystem functions in coastal areas. This study aims to analyze changes in the area and density of mangroves in Serang City, Banten. The method used is remote sensing through interpretation of Landsat 5 and Landsat 8 images with analysis of changes in the area and density of mangroves in 2011 and 2021. The research procedure was carried out by grouping NDVI values ​​into 3 vegetation classes: sparse, moderate, and dense. Furthermore, a ground check was carried out to test the level of data accuracy against mangrove canopy cover using the hemispherical photography method. The results showed that the level of image accuracy in 2021 was 90%. Based on this analysis, it is known that there has been a decrease in the area and changes in mangrove density in Sawah Luhur Village, while in Banten Village it has increased. In general, in the coastal area of ​​Serang City, there was a decrease in the mangrove area between 2011-2021 which reached 13.95 ha with the main decrease occurring in mangroves with sparse vegetation class (33.14 ha). In contrast, mangroves with medium and dense density categories increased to 19.19 ha. The decrease in mangrove area was due to abrasion, conversion into ponds, and illegal logging. The results of the analysis also showed that the correlation between NDVI values ​​and the percentage of canopy cover had a value of 0.696 which was included in the strong category.
