Abstract

Southern waters of Malang are one of the areas in the south of Java where some of its coastal areas have not been electrified. The purpose of this research is to determine the magnitude of wave energy potential in the waters of South Malang. The theoretical amount of wave energy is obtained through wave data processing (wave period, significant wave height, and wave direction) and the results are in the form of the wave energy value with the highest value in 2021 occurring in August with an average value of 40 kW /m - 50 kW/m while in 2022 the highest value occurs in July with an average value of 40 kW/m to 50 kW/m. The technical potential value of wave energy is calculated by adding the efficiency formula from AquaBuOY so that results with the highest technical wave energy potential value are obtained in 2021 in August with an average value of 40 kW/m - 50 kW/m while in 2022 the highest potential wave energy value occurs in July with an average value of 40 kW/m - 50 kw/m. Potential locations are determined based on theoretical and technical potential results and the suitability of placing AquaBuOY so that a station point that meets these criteria is obtained, namely at the 29, 30, and 34 where station 30 is the station that has the closest criteria to effectively installing buoys with the total theoretical energy is 4838.46 MW and technically it is 4354.61 MW in 2021 while in 2022 the total theoretical energy is 4387.95 MW and technically it is 3977.38 MW.

Abstract

Ikan ekor kuning (Caesio cuning) merupakan komoditas unggulan bagi nelayan di Karimunjawa karena memiliki nilai ekonomis tinggi. Namun, produksi tangkapan yang fluktuatif mengakibatkan pendapatan nelayan menjadi tidak stabil, menimbulkan tantangan ekonomi di sektor ini. Pengelolaan tingkat pemanfaatan ikan ini perlu dioptimalkan dengan memperhatikan etika lingkungan. Salah satu pendekatan yang dapat diterapkan adalah penentuan indeks musim penangkapan, yang mempertimbangkan pola penangkapan agar kegiatan penangkapan dapat berlangsung efektif dan efisien. Penelitian ini bertujuan menentukan indeks musim penangkapan ikan ekor kuning yang optimal menggunakan metode rata-rata bergerak (moving average) berdasarkan analisis runtun waktu, sehingga penangkapan dapat dioptimalkan secara berkelanjutan. Data yang digunakan meliputi produksi tangkapan ikan ekor kuning dari alat tangkap panah, bersumber dari statistik perikanan Pelabuhan Perikanan Pantai (PPP) Karimunjawa antara Tahun 2017 - 2023. Hasil menunjukkan bahwa ikan ekor kuning memiliki musim puncak penangkapan yang terjadi pada musim barat (Jan dan Feb) dan musim transisi I (Mar, Apr, Mei) dengan IMP > 100%, sementara indeks terendah terjadi pada musim transisi II (Sep, Okt, Nov) yang menjadikan bulan tersebut dalam kategori tidak musim penangkapan (IMP<100). Nilai indeks tersebut menunjukkan pola fluktuasi musim penangkapan yang dapat dijadikan dasar pengambilan keputusan dalam pengelolaan perikanan berkelanjutan, guna meningkatkan efektivitas penangkapan dan keberlanjutan ikan ekor kuning serta mendukung kesejahteraan nelayan di Kawasan Karimunjawa.   Yellowtail (Caesio cuning) is a leading commodity for fishermen in Karimunjawa because it has high economic value. However, fluctuating catch production results in unstable income for fishermen, creating economic challenges in this sector. The management of the utilization level of this fish needs to be optimized by considering environmental ethics. One approach that can be applied is determining the fishing season index, which considers fishing patterns so that fishing activities can occur effectively and efficiently. This study aims to determine the optimal yellowtail fishing season index using the moving average method based on time series analysis to optimize fishing sustainably. The data used includes the production of yellowtail catches from spearfishing fishing gear, sourced from the Karimunjawa Fishing Port (PPP) fisheries statistics between 2017 to 2023. The results are that yellowtail have a peak fishing season that occurs in the Northwest monsoon season (Jan and Feb) and transition I (Mar, Apr, May) with an (FSI>100%), while the lowest index occurs in transition II (Sep, Oct, Nov) which makes the month in the category of non-fishing season (FSI<100). The index value shows the pattern of fishing season fluctuations that can be used as a basis for decision-making in sustainable fisheries management to increase the effectiveness of fishing and the sustainability of yellowtail and support the welfare of fishermen in Karimunjawa.

Abstract

Variabilitas Suhu Permukaan Laut (SPL) dan sebaran klorofil-a di Perairan Muncar (Selat Bali) sangat mempengaruhi hasil tangkapan ikan yang didaratkan di Pelabuhan Perikanan Pantai (PPP) Muncar. Informasi mengenai hal ini penting untuk kajian pendugaan dinamika penangkapan ikan melalui penginderaan jauh. Penelitian ini bertujuan untuk mengetahui variabilitas parameter oseanografi pada tahun 2018 hingga 2022, serta dinamika penangkapan ikan di Perairan Selat Bali, khususnya di PPP Muncar. Data yang digunakan dalam penelitian ini meliputi SPL dan klorofil-a dari satelit Aqua-MODIS level 3 dan data produksi ikan dari PPP Muncar selama 5 tahun. Hasil analisis menunjukkan fluktuasi SPL dan konsentrasi klorofil-a dengan keterkaitan erat antara keduanya. Selama periode tersebut, dinamika penangkapan ikan menunjukkan peningkatan produksi ikan lemuru dan layang pada tahun 2019, meskipun terjadi penurunan produksi pada tahun 2022 akibat peningkatan SPL yang berdampak pada stok ikan. Analisis hubungan antara anomali SPL dan klorofil-a menunjukkan bahwa konsentrasi klorofil-a meningkat saat SPL menurun dengan korelasi -0.378. Fenomena penurunan SPL di perairan Selat Bali menyebabkan adanya peningkatan nilai klorofil-a di perairan yang juga mendukung peningkatan pada hasil produksi ikan. Sedangkan peningkatan SPL yang berkontribusi pada menurunnya hasil produksi ikan. Pemahaman mengenai keterkaitan antara SPL dan klorofil-a dapat digunakan salah satu pertimbangan dalam merumuskan strategi pengelolaan sumber daya ikan yang lebih berkelanjutan, guna meningkatkan produksi perikanan di wilayah tersebut di masa depan.   Sea Surface Temperature (SST) variability and chlorophyll-a distribution in the Muncar Waters (Bali Strait) have been demonstrated to significantly impact the catch of fish landed at Muncar Fishing Port. This information is crucial for the study of estimating fishing dynamics through remote sensing. The present study aims to ascertain the variability of oceanographic parameters from 2018 to 2022, as well as the dynamics of fishing in the Bali Strait Waters, with a particular focus on the Muncar Fishing Port.The study utilizes data from the Aqua-MODIS satellite level 3, which includes SPL and chlorophyll-a measurements, along with fish production data from PPP Muncar over a five-year period. The analysis revealed fluctuations in SST and chlorophyll-a concentrations, with a close relationship between the two parameters. During the observed period, fishing dynamics exhibited an increase in Bali Sardinella and Indian Scad production in 2019, followed by a decrease in 2022, attributed to an increase in SPL, which impacted fish stocks. The analysis revealed a negative correlation between SPL and chlorophyll-a anomalies, with chlorophyll-a concentrations increasing as SPL decreased, as indicated by a correlation coefficient of -0.378. The observed phenomenon of decreasing SPL in the waters of the Bali Strait is concomitant with an increase in chlorophyll-a concentration, thereby supporting an increase in fish production. Conversely, an increase in SPL is associated with a decrease in fish production. A comprehensive understanding of the intricate relationship between SPL and chlorophyll-a can inform the development of more sustainable fish resource management strategies, with the ultimate goal of enhancing fisheries production in the region.

Abstract

AbstractPerairan Malang Selatan merupakan daerah yang potensial sebagai daerah penangkapan ikan. Keberadaan berbagai jenis ikan pelagis kecil terutama ikan planktivor secara langsung dipengaruhi oleh pertumbuhan fitoplankton dan zooplankton. Fitoplankton mempunyai peran penting sebagai dasar rantai makanan dalam ekosistem perairan, sedangkan zooplankton merupakan herbivor pemangsanya. Pertumbuhan fitoplankton dan zooplankton dipengaruhi oleh faktor oseanografinya. Penelitian ini bertujuan untuk mengetahui variasi komunitas plankton dan hubungannya dengan parameter oseanografinya, serta distribusi spasial plankton di daerah penangkapan ikan di Perairan Malang Selatan, Jawa Timur. Metode purposive sampling dengan teknik zigzag pada 10 titik sampling digunakan dalam pengambilan data pada penelitian ini. Sedwicgk rafter counting cell digunakan dalam metode penghitungan plankton. Sampel plankton diambil secara horizontal dan vertikal pada kedalaman 1 dan 15 m dengan jaring plankton bermata jaring 20 µm, sedangkan parameter oseanografi secara in situ diukur menggunakan aqua quality sensor tipe AAQ 1183 C. Hasil penelitian menunjukkan bahwa kelimpahan fitoplankton sebesar 49.764 sel/m3, didominasi oleh genus Chaetoceros. (Bacillariophyceae), dan kelimpahan zooplankton sebesar 894 ind/m3, didominasi oleh genus Nauplius. (Copepoda). Indeks keanekaragaman dan keseragaman fitoplankton dan zooplankton dapat dikategorikan sedang, berturut-turut sebesar 1,77–1,85 dan 1,70–1,77; 0,58–0,59 dan 0,77–0,79, sedangkan indeks dominansinya masuk dalam kategori rendah yaitu berturut-turut 0,27–0,28 dan 0,24–0,27. Analisis Principal Component Analysis (PCA) menunjukkan bahwa parameter oseanografi utama yang paling berpengaruh pada variasi komunitas plankton adalah turbiditas, klorofil-a, oksigen terlarut dan fosfat. Hasil uji T menunjukkan bahwa distribusi spasial kelimpahan fitoplankton dan zooplankton pada kedalaman 1 m dan 15 m berbeda nyata. Studi ini memberikan informasi penting tentang kelimpahan plankton dan faktor oseanografi yang berpengaruh di daerah penangkapan di Perairan Malang Selatan. Kata Kunci: komunitas plankton, parameter oseanografi, fishing ground, Perairan Malang Selatan AbstractThe South Malang water is a potential area as a fishing ground. The existence of various species of small pelagic fishes such as planktivores fishes are directly influenced by the growth of phytoplankton and zooplankton. Phytoplankton has an important role as the basis of the food chain in aquatic ecosystems, whereas zooplankton is its predator. The growth of phytoplankton and zooplankton is influenced by oceanography factors. This study aims to determine the variation of the plankton community and its relationship with oceanographic parameters, as well as the spatial distribution of plankton in the fishing ground at South Malang water. The purposive sampling method with zigzag technique at 10 sampling sites was used in data collection in this research. Sedwicgk rafter counting cells were used in plankton counting methods. The plankton samples were taken horizontally and vertically at depths of 1 and 15 m with a 20 μm planktonnet, while in situ oceanographic parameters were measured using aqua quality sensor AAQ type 1183 C. The results showed that phytoplankton abundance was 49.764 cells / m3, dominated by the genus Chaetoceros (Bacillariophyceae), and zooplankton abundance of 894 ind / m3, dominated by the genus Nauplius (Copepoda). The diversity index and uniformity index of phytoplankton and zooplankton could be categorized as the middle as 1.77-1.85 and 1.70-1.77; 0.58-0.59 and 0.77-0.79, respectively, while the dominance index was included in the low category that was 0.27-0.28 and 0.24-0,27, respectively. Principal Component Analysis (PCA) analysis showed that the most important major oceanographic parameters for plankton community variation were turbidity, chlorophyll-a, dissolved oxygen and phosphate. T test results show that the spatial distribution of phytoplankton abundance and zooplankton at depth of 1 m and 15 m are significantly different. This study provides important information on the plankton abundance and oceanography factors affected at fishing ground of South Malang water. Keywords: Plankton community, oceanography parameters, fishing ground, South Malang Water

Abstract

Penelitian ini dilaksanakan di perairan Teluk Prigi pada bulan Mei 2017 di 18 titik stasiun. Parameter suhu, salinitas dan oksigen terlarut diukur secara langsung di lapangan dengan menggunakan alat sensor AAQ 1183 pada kedalaman 1, 5 dan 10 meter, sedangkan parameter kedalaman diukur menggunakan alat Echosounder GPS Map 585. Tujuan dari penelitian ini adalah untuk mengetahui distribusi suhu, salinitas dan oksigen terlarut dan hubungannya terhadap kedalaman di stasiun pengukuran perairan Teluk Prigi. Berdasarkan hasil pengukuran terdapat perbedaan distribusi yang cukup ekstrem, baik itu distribusi suhu, salinitas maupun oksigen terlarut. Perbedaan distribusi tersebut ditemukan pada stasiun 2 (kawasan muara sungai) dan stasiun 5 (kawasan pantai Pasir Putih). Pada distribusi suhu, suhu tinggi terdapat di stasiun 2 sebesar 28,18 oC, dan suhu rendah terdapat pada stasiun 5 sebesar 26,72 oC. Salinitas tinggi terdapat pada stasiun 5 sebesar 34,10 ‰ dan salinitas rendah terdapat pada stasiun 2 sebesar 32,31 ‰. Kadar oksigen terlarut tinggi terdapat pada stasiun 2 sebesar 8,40 ppm dan kadar oksigen terlarut rendah terdapat pada stasiun 5 sebesar 7,99 ppm. Perbedaan distribusi antara stasiun 2 dan stasiun 5 terjadi karena adanya pengaruh internal yaitu perbedaan batimetri/kontur kedalaman pada kedua stasiun tersebut. Stasiun 2 memiliki kedalaman yang dangkal yaitu sekitar 4 meter dan stasiun 5 dengan kedalaman yang relatif dalam yaitu sekitar 24 meter. Berdasarkan hasil tersebut dapat disimpulkan bahwa informasi batimetri pada perairan teluk, penting untuk dipelajari karena sangat berpengaruh terhadap distribusi kualitas perairan.

Abstract

Graphical Abstract   Highlight Research The author mentioned four highlights from their research: 1. GIS and AHP were integrated to assess land suitability for Pangasius aquaculture in Tulungagung Regency. 2. 59% of the region (976,885.71 ha) was identified as suitable or highly suitable for aquaculture expansion. 3. Water quality, soil conditions, and infrastructure were key factors influencing aquaculture feasibility. 4. Sustainable planning is needed to balance aquaculture expansion with existing land uses like agriculture and settlements. 5. The GIS-based model serves as a policy tool for efficient and sustainable Pangasius aquaculture development.     Abstract Tulungagung Regency in East Java Province has an export demand of 300,000-400,000 tons per year. The high demand for exports spurred the people and government of Tulungagung Regency to develop pangasius aquaculture areas. This will have a negative impact if carried out without a land suitability assessment. The study aimed to analyze the parameters of pangasius aquaculture and map the potential areas for pangasius aquaculture using AHP and GIS-based analysis. This research was conducted from January to August 2022 in Tulungagung Regency, Indonesia. Several stages were carried out, including primary data collection (water quality, soil quality, and infrastructure), secondary data collection (literature, reports, fisheries statistics data, government statistical data, and journals/articles), application of land suitability assessment, and pangasius farming area suitability analysis. Land suitability analysis consists of measuring water quality parameters (DO, temperature, TDS, pH, ammonia, and nitrate), soil quality (texture, pH, and slope), and infrastructure (roads, markets, hatcheries, and fillet factories) using the Analytical Hierarchy Process method (AHP), which includes standardization, determination of weights, and combining the weights of land suitability maps, which are then mapped by ArcGIS Software. Most of the land conditions for the pangasius aquaculture areas in Tulungagung Regency are moderately suitable, suitable, and most suitable, with percentages of 30, 21, and 28%. The area that can be developed for pangasius aquaculture is 976885.71 ha, with the most suitable category being 2619.35 ha, the appropriate category being 2235.74 ha, and the most suitable category being 4913.77 ha.

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
