Abstract

This study attempted to analyze the distribution and contamination status of heavy metals (Cu, Fe and Zn) along western coast of Bali Strait in Banyuwangi, East Java. Bali Strait is one of the many straits in Indonesia with high fisheries activities that could potentially contributed to high heavy metal pollution. There were five sampling areas from the north to south: Pantai Watu Dodol, Pantai Kalipuro, Ketapang Port, Pantai Boom and Muncar as the fish landing area. Heavy metal pollution in these locations comes from many different activities such as tourism, fish capture and fish industry and also domestic activities. Contamination factor (CF), geo-accumulation index (Igeo) and enrichment factor (EF) of each heavy metal were calculated to obtain contamination status of the research area. The concentrations of Fe were observed the highest (1.5-129.9 mg/kg) followed by Zn (13.2-23.5 mg/kg) and Cu (2.2-7.8 mg/kg). The distribution of Cu, Fe and Zn showed variability among the sampling locations in which high concentrations of Cu and Zn were higher in Ketapang Port, whereas high concentration of Fe was high in almost all sampling locations. According to the pollution index, contamination factors of Cu, Fe and Zn were low (CF < 1 and Igeo < 1). However, high index of EF (> 50) showed high influence of the anthropogenic activities to the contribution of the metals to the environment. This could also because of the high background value used in the calculation of the index due to the difficulties in finding background value from the sampling areas.Keywords: heavy metals, pollution index, contamination factor, geo-accumulation index, Bali Strait

Abstract

The southern waters of Java are suitable to be the largest supplier of Yellowfin tuna exports in Indonesia, but have not efficiently produced the expected yield. This research minimizes these constraints by modeling the yellowfin tuna fishing grounds in the southern waters of Java based on oceanographic factors such as Sea Surface Temperature (SST), chlorophyll-a (CHL_A), Sea Surface Salinity (SSS), Sea Surface Height (SSH) using an integration between remote sensing, Geographic Information Systems (GIS), and the Generalized Additive Model (GAM) statistical method. This study used oceanographic factor data from Aqua MODIS Level-3 and Copernicus, while yellowfin tuna fishery production was obtained from Palabuhanratu Nusantara Fishing Port (NFP), Cilacap Ocean Fishing Port (OFP), and Pondokdadap Coastal Fishing Port (CFP). The modeling process used 80% of the data, while the remaining 20% was used to validate the model results. The order of influence of oceanographic parameters from largest to smallest is SST > SSS > SSH > CHL-A. The best model from the GAM analysis showed that the combination of four oceanographic parameters had the greatest influence on yellowfin tuna CPUE. The catch per unit effort (CPUE) of yellowfin tuna was predicted to be high in May-October and low in November-April. The prediction model had high accuracy because most of the fishing activity was in the HSI 0.4-0.5 range and the RMSEP value was 0.63. Yellowfin tuna were suitable in habitats distributed from inshore to offshore in June and July, but less suitable in December.

Abstract

Banyuurip is one of villages in Ujung Pangkah District, Gresik with high aquaculture activities of Perna viridis. Green mussels are highly produced in that area, however Banyuurip waters also has potential risk of heavy metals pollution. Therefore, this research was conducted to understand the concentrations of Fe and Zn in the sediments and in the Green Mussels. The heavy metals concentration will be used to analyze Bio Concentration Factor (BCF) and Human Health Risk Assessments (HHRA). A total about 45 P. viridis populations were collected from 3 sites in Banyuurip waters. In order to obtain a representative sample at each site, 15 populations of Green Mussels with similar shell lengths and bottom sediment were collected. Mussel’s tissue and bottom sediment were analyzed using AAS (AAnalyst700) to determine the concentrations of Fe and Zn. The concentrations of Fe were found almost similar with the concentrations of Zn in P. viridis within the range of Fe = 3.10 – 5.25 mg.kg-1 and Zn = 3.91 - 4.67 mg.kg-1. BCF (o-s) of Fe in P. viridis is lower than the BCF (o-s) of Zn, because the concentrations of Fe in the mussels were less than the concentrations in the sediments. According to the Target Hazard Quotients (THQ) values (THQ < 1), both heavy metals are not likely causing negative health effects for human during lifetime. However, Estimated Daily Intakes (EDI) values are above Provisional Tolerable Daily Intakes (PTDI) standard means it can cause negative effects due to daily consumption (EDI > PTDI).

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

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

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.
