Abstract

The objective of this study was to find out the antioxidant activities along with phytochemical screening of R. mucronata leaf extracts. R. mucronata leaves were collected from Pilang, Probolinggo. The extraction use three different solvents with different polarity (Methanol, Ethyl acetate, and Hexane). The antioxidant activities were determinted by the Diphenyl picryhydrazil (DPPH) metode used four different concentrations (31,25; 62,25; 125; and 250 ppm). The antioxidant analysis of mangrove R. mucronata showed that the ethyl acetate extract has the highest antioxidant activity (160,417 µg/ml) than the methanol (-117,498 µg/ml) and the hexane (327,611 µg/ml) extracts. The phytochemical screening results that the methanol extract contains 1195 µg/ml flavonoid compounds, 124,44 µg/ml alkaloid compounds and 576,64 µg/ml of tannin compounds. Meanwhile the ethyl and the hexane extract contains  alkaloid compounds (44,91 µg/ml and 41,49 µg/ml ) and tannin compounds (84,84 µg/ml and 67,30 µg/ml).

Abstract

Tourist activity significantly impacts coastal ecosystems, often leading to increased marine debris pollution. This study examines the influence of tourism on beach cleanliness by analyzing marine debris composition, abundance, and Clean Coast Index (CCI) at four recreational beaches in Prigi Bay, Trenggalek, Indonesia (Cengkrong, Prigi, Karanggongso, and Mutiara). Sampling was conducted in March–April 2024, using a 5×5 m quadrat transect method placed at 20 m intervals along the shoreline in the backshore zone. The Mann-Whitney U test was applied to assess differences in debris accumulation between weekdays and weekends. Results indicated that plastic debris was the dominant type across all sites, with debris abundance slightly higher on weekends (54%) than weekdays (46%). Moreover, the mass of accumulated debris was significantly greater on weekends (1.93 items.m⁻², 8.86 g.m⁻²) than on weekdays (1.57 items.m⁻², 4.69 g.m⁻²), primarily due to an increase in larger debris items (10–100 cm), likely associated with tourism-related waste such as food packaging and recreational items. Despite these fluctuations, all beaches exhibited "extremely dirty" CCI scores (>20), indicating persistent pollution beyond tourism activity. Additional contributing factors may include inefficient waste management, fishing-related debris, and marine transport mechanisms. These findings underscore the urgent need for comprehensive waste management strategies, including source reduction, regular cleanups, improved waste disposal infrastructure, and public awareness campaigns, to mitigate long-term environmental and socio-economic impacts in Prigi Bay. Furthermore, integrating this measure into sustainable coastal tourism planning is crucial to balance recreational use with environmental preservation.

Abstract

Bacteria are microscopic organisms, and a small portion of them are pathogenic or harmful to living organisms. One example is bacteria that cause damage and decay in captured Tuna fish (Thunnus sp.) off the coast of Kondang Merak, Malang. Therefore, to determine the genus of bacteria found in Tuna fish (Thunnus sp.), bacterial morphology identification was conducted. Bacterial morphology identification was performed using methods involving the identification of colony and cell morphology, as well as bacterial respiration tests to enhance genus prediction accuracy. Bacterial morphology identification involved several testing stages, including Gram-staining, cell observation and measurement, motility testing, and bacterial respiration testing. The bacterial isolation samples from Tuna fish (Thunnus sp.) on TSA media consisted of 8 samples, namely 1a, 1b, 2a, 2b, 3, 4a, 4b, and 5, which were differentiated based on bacterial colony morphology. Based on the results of colony morphology identification, cell morphology, and respiratory testing, all 8 bacterial samples were manually identified with reference to identification books. The identification results showed that several samples had similar morphological characteristics. The bacterial morphology identification results for samples 2a and 2b were identified as belonging to the genus Aeromonas; samples 4a and 4b were classified into the genus Mesophilobacter; sample 1a was categorized into the genus Carnobacterium; and samples 1b, 3, and 5 belonged to the genus Vibrio.

Abstract

Senyawa organik volatil atau volatile organic compounds (VOC) adalah kelompok senyawa yang sering ditemukan di lingkungan perairan yang memiliki dampak negatif pada ekosistem dan kesehatan manusia. Keberadaan VOC di perairan dapat disebabkan oleh produksi dan penggunaan senyawa ini secara berkepanjangan. Sungai Sedati terletak di daerah perkotaan telah menerima masukan senyawa ini dari kegiatan rumah tangga, bahan baku industri, pertanian dan budidaya perikanan. Pendeteksian VOC di badan dan muara Sungai Sedati dilakukan menggunakan Solid Phase Microextraction (SPME) dan Gas Cromatography-Mass Spectrometry (GCMS). Selain itu, penelitian ini juga mengevaluasi kualitas perairan berupa pH, DO, salinitas, suhu, dan arus. Total 39 senyawa diperoleh dari Perairan Sedati, dimana senyawa-senyawa tersebut digunakan sebagai bahan kimia industri, bahan kimia farmasi, produk pembersih, produk perawatan pribadi, plasticizer, dan pestisida. Penggunaan tertinggi sebanyak 17 senyawa digunakan sebagai bahan kimia industri dan tujuh senyawa sebagai pestisida. Cemaran VOC didominasi oleh fenol (2,4-di-tert-butilfenol; 3,5-di-tert-butilfenol). Analisis kualitas air menunjukkan bahwa kualitas Perairan Sedati masih dalam ambang batas baku mutu air sungai kelas III dan baku mutu air laut. Penelitian ini memberikan informasi mengenai potensi dampak VOC, dan pentingnya pengelolaan limbah perkotaan yang lebih berkualitas untuk ekosistem perairan dan kesehatan manusia.  Volatile organic compounds (VOCs) are a group of chemicals that are frequently detected in aquatic environments, and show negative impacts on ecosystem and human health. The existence of VOCs in the waters may be obtained from their massive production and application. The Sedati River is located in an urban area that has received impacts from household activities, industrial raw materials, agriculture, and aquaculture. The detection of VOCs in the body and the river mouth of Sedati River was determined by Solid Phase Microextraction (SPME) and Gas Chromatography-Mass Spectrometry (GCMS). Water quality of the Sedati River was evaluated, namely pH, DO, salinity, temperature, and water current. A total of 39 compounds were detected in the Sedati River. Most of them were used in industrial chemicals, pharmaceutical chemicals, cleaning products, personal care products, plasticizers, and pesticides. 17 compounds were highly used as industrial chemicals, whereas seven compounds were lowly used as pesticides. The phenol (2,4-Di-tert-butylphenol; 3,5-Di-tert-butylphenol) was a dominant compound in the Sedati River. The water quality was in agreement with the water quality standards. This study provides information about the impacts of VOC in the water and the importance of water quality treatments for healthy ecosystems and humans.

Abstract

Seagrass, yang umum disebut sebagai lamun dalam bahasa indonesia merupakan satu satunya tumbuhan tingkat tinggi yang dapat hidup terendam air laut. Padang lamun memiliki peran kunci dalam ekosistem, antara lain sebagai produsen primer, habitat hidup organisme bentik, menstabilkan sedimen, dan menyimpan karbon di laut dangkal. Komunitas lamun monospesies dapat ditemukan di Kabupaten Malang, namun penelitian terkait lamun di Kabupaten Malang juga masih terbatas, sehingga kajian ini dirasa penting untuk dilakukan. Tujuan dari kajian ini untuk mengetahui laju pertumbuhan daun dan biomassa lamun, serta mengetahui kandungan fitokimianya. Penelitian ini dilakukan pada bulan Agustus hingga November Tahun 2014 dan Tahun 2015. Pengukuran laju pertumbuhan daun dan biomassa lamun dilakukan secara in situ dengan metode penandaan selama satu minggu, serta pengambilan contoh daun lamun dilakukan secara acak di lokasi penelitian. Tahap selanjutnya bahan diekstraksi dengan methanol untuk mendapatkan kandungan senyawa fitokimia. Analisis data di Laboratorium Eksplorasi Sumberdaya Perikanan dan Kelautan, FPIK–UB. Hasil penelitian menunjukkan bahwa terdapat dua jenis lamun, yaitu Syringodium isoetifolium di Pantai Kondang Merak dan Thalassia hemprichii di Pantai Bale Kambang. Laju pertumbuhan daun kedua jenis lamun secara berurutan menunjukkan nilai positif yaitu 0,45±0,19 cm/hari dan 0,25±0,14 cm/hari. Nilai biomassa kedua jenis lamun menunjukkan bahwa biomassa pada bagian bawah substrat lebih tinggi dibandingkan bagian atas substrat. Uji fitokimia menunjukkan bahwa kedua jenis lamun ini mengandung senyawa bioaktif jenis flavonoid dan saponin.

Abstract

Anchovies have an economical price, high nutritional value, and a savory and delicious taste. As a result, they are widely favored by the public and are very easily obtained in traditional markets, including the Anduonohu Market in Kendari. The objectives of this study were to determine (1) the diversity of small fish species in the anchovy population sold at Anduonohu Market, Kendari through morphological characteristics; and (2) the status of these species in IUCN and CITES. The collection of the anchovy population was carried out in December 2021 at Anduonohu Market, Kendari, Southeast Sulawesi. Data analysis of fish species and their status in the International Union for Conservation of Nature (IUCN) and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) was carried out descriptively by considering the morphology and morphometry of the fish, adjusted to FishBase, a World Wide Web electronic publication www.fishbase.org. There are two types of small fish in Anduonohu Market, namely lureh (anchovy) and small rembang. Meanwhile, in the anchovy population, ten other species of small-sized fish were found. All identified small fish species have an IUCN status of least concern - low risk and have not been evaluated in CITES.
