Abstract

Latar belakang: Sampah puntung rokok termasuk sampah laut yang menjadi perhatian khusus karena masih rendahnya kesadaran masyarakat untuk membuang di tempat semestinya. Kandungan kimia pada puntung rokok berpotensi mencemari lingkungan yang berdampak pada perkembangan biota, bahkan dapat menyebabkan kematian. Penelitian ini dilakukan untuk menganalisis karakteristik puntung rokok (ukuran, tipe dan merek) serta tingkat polusinya berdasarkan Cigarette Butt Pollution Index (CBPI). Lima pantai wisata di Kabupaten Malang Selatan dipilih sebagai area kajian karena tingginya aktivitas wisata yang berkontribusi terhadap peningkatan sampah puntung rokok di wilayah pesisir.Metode: Pengambilan sampel puntung rokok dilakukan pada bulan Juli hingga Agustus 2024 di Pantai Balekambang, Kondang Merak, Sendang Biru, Gatra, dan Clungup. Pengambilan sampel puntung rokok menggunakan metode transek garis berukuran 5 x 5 m yang diletakkan sejajar garis pantai di zona supratidal dan intertidal. Variabel dalam penelitian ini yaitu jumlah, kepadatan, dan tingkat pencemaran puntung rokok. Alat yang digunakan berupa roll meter, tali, pasak, plastik zip, timbangan analitik, dan marine debris identifier. Analisis data menggunakan Uji Mann-Whitney untuk membandingkan kepadatan puntung rokok di supratidal dan intertidal, serta Uji Kruskal-Wallis untuk membandingkan kepadatan puntung rokok di kelima pantai.Hasil: Sebanyak 1,877 sampah puntung rokok ditemukan dan paling banyak di zona supratidal yang didominasi ukuran 2.5–5 cm. Jumlah puntung rokok dalam penelitian ini tidak jauh berbeda dengan penelitian sebelumnya, namun kepadatannya sangat tinggi berkisar antara 0.06 hingga 1.67 item/m2. Puntung rokok didominasi oleh ukuran  2.5–5 cm bertipe utuh, kecuali Pantai Clungup didominasi oleh ukuran 0.5–2.5 cm bertipe rusak. Gudang Garam menjadi merek yang mendominasi di tiap pantai selain Pantai Clungup. Nilai kepadatan tertinggi ditemukan di Pantai Sendang Biru dan nilai terendah ditemukan di Pantai Clungup, nilai ini berbanding lurus dengan tingkat polusi berdasarkan CBPI.Simpulan: Variasi karakteristik sampah puntung rokok di kelima pantai dipengaruhi adanya perbedaan aktivitas antropogenik dan faktor hidrooseanografi. ABSTRACTTitle: Analysis of Characteristics of Cigarette Butts and Assessment of the Cigarette Butt Pollution Index (CBPI) on the Coast of South Malang Regency, East Java Background: Cigarette butts are a type of marine debris that require special attention due to the low public awareness of proper disposal. The chemical contents in cigarette butts have the potential to pollute the environment, affecting the development of marine biota and even causing death. This study was conducted to analyze the characteristics of cigarette butts (size, type, and brand) and their pollution level based on the Cigarette Butt Pollution Index (CBPI). Five tourist beaches in South Malang Regency were selected as study sites due to the high tourist activity that contributes to the increase in cigarette butt litter along the coastal area.Method: Cigarette butt samples were collected from July to August 2024 at Balekambang, Kondang Merak, Sendang Biru, Gatra, and Clungup Beaches. The sampling was conducted using 5 × 5 m line transect method placed parallel to the shoreline in both the supratidal and intertidal zones. Variables in this study included the number, density, and pollution level of cigarette butts. The tools used were a roll meter, rope, stakes, ziplock plastic bags, an analytical scale, and a marine debris identifier. Data were analyzed using the Mann-Whitney Test to compare cigarette butt densities between supratidal and intertidal zones and the Kruskal-Wallis Test to compare densities across the five beaches.Result: A total of 1,877 cigarette butts were found, mostly in the supratidal zone, dominated by butts sized 2.5–5 cm. The number found is similar to previous studies, but the density was very high (0.06 to 1.67 items/m²). Most butts were intact, except in Clungup where damaged butts sized 0.5–2.5 cm dominated. Gudang Garam was the dominant brand, except in Clungup. The highest density was in Sendang Biru, the lowest in Clungup, matching CBPI values.Conclusion: Variations were influenced by anthropogenic activity and hydro-oceanographic factors.

Abstract

Graphical Abstract Highlight Research The size of the first mature gonads in hulu'u fish can be analyzed. Differences in sperm and egg size characterize sexual maturity. Sexual maturity is not influenced by season. Hulu'u fish have an asynchronous spawning type. Abstrack Understanding fish reproduction biology, particularly sexual maturity, the reproductive cycle, and fecundity, is useful for managing fisheries. The reproduction of Giuris margaritaceus in Limboto Lake is regrettably unknown. Over a year, fish specimens (N = 662) were gathered. They ranged in length from 6.5 to 20.9 cm (mean SD 10.9±2.5). Fecundity varied from 30,057 to 61,920. The first sexual maturity of male and female fish occurred at different sizes, 11.2 cm and 10.3 cm, respectively. This information is needed to determine this fish's lowest acceptable harvest length under the management aim to enter all-female fish for reproduction at least once. We estimated the reproductive of G. margaritaceus cycle using the size of the oocytes, histological analysis of the ovaries, and monthly mean GSI. These techniques produced the same reliable conclusion: G. margaritaceus can spawn yearly, with maximal between September and October. Based on this finding, spawners of Giuris margaritaceus can be kept from entering the reproductive stock between September and October. Future efforts to fine-tune fishing efforts for the effective management of G. margaritaceus may be aided by the study's findings.

Abstract

Graphical Abstract Highlight Research A low sequence divergence of lemuru between Bali Strait and the northern latitude. S. lemuru migration route through ITF will maintain its nucleotide variation. The high haplotype diversity of lemuru is a testament to its adaptability. S. lemuru's high haplotype diversity supports their stock recovery in the Bali Strait. Two sardine species are morphologically and genetically highly distinct, even though they prefer overlapping water mass conditions from each other. Abstract Sardinella lemuru is known as the native pelagic fish of the Bali Strait. However, its presence has recently become challenging to find. This study aimed to validate S. lemuru using molecular taxonomy and link it to water circulations for sustainable management. It is the first study of relatively complete sequence data on S. lemuru in the Bali Strait. A total of 47 sequences were amplified using the control region gene of mitochondrial DNA. Other S. lemuru (n = 4) and Amblygaster sirm (n = 12) sequences were retrieved from GenBank. Low sequence divergence is observed in clade-1 of S. lemuru across the Bali Strait, Manado-Sulawesi, and Kudat-Malaysia. This is probably due to its migration using the main Indonesian ThroughFlow (ITF). There is an evolutionary divergence between two groups of S. lemurs, measuring 35.3%±4.1. The first signs of these cryptic groups were found at Canggu and Prigi, with 87 base-pair differences between the two groups. This study also presents strong evidence that A. sirm prefers overlapping water mass conditions with S. lemuru in the Bali Strait but is morphologically and genetically distinct. Notably, three samples of A. sirm in Kedonganan-Bali are clustered with other A. sirm locations passed by the primary and secondary South China Sea throughflow. The high genetic diversity of S. lemuru among Bali Strait sites demonstrates its adaptive ability, with scattered single-frequency haplotypes. The adaptive ability traits of S. lemuru support its stock recovery. The stock recovery recommendation is based on finding S. lemuru’s adaptive traits within their populations in suitable habitats and climatic conditions

Abstract

The DNA barcoding technique is primarily utilized to rapidly identify species, particularly when samples are damaged and cannot be identified accurately through morphological methods. This approach utilizes polymerase chain reaction (PCR) technology to amplify DNA fragments from the targeted species, with its success largely due to the design of the primers employed. The cytochrome c oxidase subunit I (COI) gene, a mitochondrial gene, is frequently targeted in DNA barcoding and has been proven effective in distinguishing species. At Pondokdadap Port, over 90% of the fish caught consist of skipjack tuna, yellowfin tuna, and mackerel (T2C). This study aimed at designing silico DNA barcoding primers for these three species. The successful development of these primers may facilitate the documentation and understanding of the genetic diversity of the species under study, which is crucial for efficient and effective fisheries management. The primer design process applied Primer-BLAST software from the NCBI website, followed by additional testing with OligoAnalyzer. The selected primer pairs were the forward primer 5'-GGCCCATGCCTTCGTAATGA-3' and the reverse primer 5'-GCAGGGTCGAAGAAGGTTGT-3'. These primers successfully amplified the DNA of T2C fish, with PCR results indicating that the optimal annealing temperature for these primers was 55 °C

Abstract

Blacktip Reef Sharks (Carcharinus melanopterus) is one of many sharks that are found in Indo-pasific waters and currently listed as vulnerable in IUCN Redlist due to a decrease in population. Habitat suitability and environmental parameters are one of the factors that influence the presence of populations. This research focuses on habitat suitability of Blacktip Reef Sharks pups nursery grounds on the coast of Jinato and Tinabo Besar island, Taka Bonerate National Park with differences in environmental conditions and zone types. Therefore, this research was conducted to analyze the state of environmental parameters at both study site and analyze the influence of parameters and compare the habitat suitability of Blacktip Reef Shark babies at both study site. Data collection was conducted primarily and secondarily in both islands In July and August 2024 and processed using Spearman correlagtion and venn diagram. The number of Blacktip Reef Shark pups on Jinato Island was found to be 3 while on Tinabo Besar Island it was found to be 207, so it is assumed that there is an influence of environmental conditions on the presence of shark pups. There are significant differences and influences on chlorophyll-a, current speed, and salinity parameters, with current being the most influential parameter in the habitat suitability of blacktip reef shark pups on both islands. Tinabo Besar Island has slower current speed conditions, indicating a higher level of habitat suitability.  Hiu Karang Sirip Hitam (Carcharinus melanopterus) merupakan salah satu hiu pada area Indo-pasifik yang termasuk kedalam Redlist IUCN dengan kategori vulnerable karena adanya penurunan populasi. Kesesuaian habitat dan parameter lingkungan merupakan salah satu faktor yang memengaruhi keberadaan populasi hiu. Penelitian ini berfokus terhadap kesesuaian habitat bayi Hiu Karang Sirip Hitam di pesisir Pulau Jinato dan Tinabo Besar, Taman Nasional Taka Bonerate dengan perbedaan kondisi lingkungan dan tipe zona yang berbeda. Oleh karena itu, penelitian ini dilakukan untuk menganalisis perbedaan parameter pada kedua pulau, menganalisis pengaruh parameter serta membandingkan kesesuaian habitat bayi Hiu Karang Sirip Hitam pada lokasi kajian. Pengambilan data dilakukan baik secara primer dan sekunder pada kedua pulau di bulan Juli dan Agustus 2024 dan diolah menggunakan uji korelasi Speaman dan diagram venn. Jumlah bayi Hiu Karang Sirip Hitam pada pulau Jinato ditemukan 3 ekor sedangkan pada Pulau Tinabo Besar ditemukan 207 ekor sehingga diasumsikan adanya pengaruh kondisi lingkungan terhadap keberadaan bayi hiu. Terdapat perbedaan dan pengaruh signifikan pada parameter klorofil-a, arus, dan salinitas dengan paremter arus sebagai paremter yang paling berpegaruh dalam kesesuaian habitat bayi Hiu Karang Sirip Hitam di kedua pulau. Pulau Tinabo Besar memiliki kondisi arus yang lebih rendah sehingga menujukkan tingkat kesesuaian habitat yang lebih tinggi.
