Abstract

Diversity and abundance of fish are rely on fitoplankton abundance as food, meanwhile abundance of phytoplankton is depend on waters quality. In order to understand relationship among those component, this study was carried out to analyzed correlation among phytoplankton abundance chlorophyll-a concentration and water quality. This study was conducted in the coastal waters of sungsang, Banyuasin Regency  from July until August 2017. Sample collected using purposive sampling method. Results of the research showed that clarity around 6.3-45.5%, turbidity 2-4 NTU, temperature 29.6-30.8oC, pH 6.0-7.7, salinity 0-16 ppt, DO 5.33-6.50 mg/L, BOD 0.4-3.6 mg/L, ammonia 0.1-0.32 mg/L, phosphate 0.01-2.16 mg/L, nitrate 0.06-2.96 mg/L, chlorophyll-a 1,68-20,6 mg/m3. There was positive correlation among chlorophyll-a and phytoplankton, phosphate, nitrate, DO, BOD5 about 95.5%, 91%, 76.6%, 82.2%, -63%, respectively. The higher the concentration of phosphate and nitrate the higher the concentration of chlorophyll-a, and the higher the concentration of chlorophyll-a causes the higher the concentration of dissolved oxygen. The higher the BOD5 and ammonia, the lower the concentration of chlorophyll-a.

Abstract

Management planning prioritization is critical as a reference for managers when they try to improve the management effectiveness of marine protected areas. The objective of this study is to analyze the prioritization of Ay-Rhun MPA's management planning using the Analytic Network Process. Problems and solutions in determining management priorities are clustered into four categories: ecology, economy, social, and institutional, and inside each cluster is sub-clusters based on the results of Focus Group Discussion. The results show that the main problem of Ay-Rhun MPA management is the ecology cluster. The sub-cluster analysis results showed that management problems should be addressed as priorities are: (1) the lack of human resource in terms of capacity and quantity; (2) the lack of understanding in conservation efforts; (3) price instability in fishery productions; (4) sand and coral mining for construction materials. Sub-cluster in a cluster could affect other elements in the same cluster, and it could also affect elements on different clusters. Therefore, recommendation strategies that should be prioritized to improve management effectiveness of Ay-Rhun MPA are (1) optimization of resource use based on carrying capacity, with the value of 0.6137; (2) MPA zonation design, with the value of 0.5484; (3) MPA management policy design, with the value of 0.5308; and (4) socialization regarding conservation efforts and understanding, with the value of 0.4680.

Abstract

Small islands are an entity that has limitations to be used. This study aimed to analyze the land carrying capacity for settlement and its implication on water quality at small islands. The carrying capacity of land are determined based on an analysis of the minimum space requirements of each individual according to Indonesian National Standards (SNI) 03-1733-2004, while the implications for water quality are determined based on the nutrient load approach. The results of this research showed that the Tiworo archypelago have a total potential land approximately 198.94 ha and about 31.45 ha of this amount has been utilized. Although the land use is relatively small, however, there are also islands that have been used to exceed their carrying capacity. The human population density of each island has a positive correlation with the level of the land degradation. The total population currently is still tolerated by water bodies, but when the population is suitable with the land carrying capacity will increase the ammonia ratio by 0.086-0.550. This indicates that the land carrying capacity of the Tiworo chained Islands is not higher than the ability of the water body in assimilating the domestic waste.

Abstract

Sea territorial of Bengkulu has abundantly fish resource which influenced by oceanographic parameters. The purpose of this research is to determine the variability of spatially and temporally oceanographic parameters and their relationships to the fish catch in Bengkulu seas for 5 years. The method used is descriptive analysis based on the data of visualization of wind speed, sea surface temperature, and salinity in the periods of 2011-2015. The data were analyzed by using GrADS software. The results show the highest of fish catch occurred on the west season of 2015 with 16.514 tons. The wind speed at that season was1.211 m/s, Sea Surface Temperature (SST) of 29.094 oC, and salinity of 33.62 psu. Mean while, the lowest fish catch on the west season of 2012 with 7,576.60 tons. The wind speed at that season was 4.624m/s, SST of 28.765 oC, and salinity of 33.987 psu. The relationship between oceanographic condition and the fish catch is generally described, i.e., when high of sea wind speed and salinity, and low sea surface temperature will be obtained low fish catch. On the contrary, when low wind speed and salinity, and high sea surface temperature will be obtained high fish catch.

Abstract

Keperluan data dan informasi tentang habitat bentik sangat diperlukan untuk menjaga dan melestarikan ekosistem yang ada di perairan. Rusaknya habitat bentik dapat terjadi karena adanya aktifitas antropogenik dan bencana alam yang akan berimbas pada biota dan ekosistem yang ada disekitarnya, oleh karena itu untuk mengetahui dan memantau kondisi perairan dan habitat perairan dangkal perlu dilakukannya pemetaan. Penelitian ini bertujuan untuk menganalisis perubahan habitat dasar perairan laut dangkal di Karang Lebar, Kepulauan Seribu. Penelitian ini memanfaatkan citra multispektral resolusi tinggi QuickBird 2008 dan WordView-2 2018 untuk mendeteksi perubahan geospasial habitat bentik. Klasifikasi citra multispektral dilakukan dengan penerapan algoritma SVM (Support Vector Machine) dan transformasi DII (Depth Invariant Index) pada kedua citra yang digunakan. Jumlah kelas habitat bentik yang dihasilkan adalah sebanyak lima kelas yaitu terumbu karang, karang mati, padang lamun, pasir, dan rubble. Hasil analisis menunjukkan akurasi keseluruhan 58,18% dan 70,9% pada penerapan klasifikasi dengan input band multispektral masing-masing untuk citra 2008 dan 2018, serta 60% dan 80% pada hasil transformasi DII masing masing untuk citra 2008 dan 2018. Perubahan kelas rubble di tahun 2008 menjadi kelas pasir tahun 2018 merupakan yang paling besar luasannya dibandingkan dengan perubahan pada kelas lainnya, yaitu 81,46 ha.

Abstract

Kawasan konservasi perairan (KKP) berfungsi untuk mengelola sumber daya perikanan dan keanekaragaman hayati laut agar dapat dimanfaatkan secara berkelanjutan. Kondisi ikan karang merupakan salah satu bioindikator untuk mengukur dampak pengelolaan KKP. Tujuan dari penelitian ini adalah untuk melihat dampak pembentukan KKP Daerah (KKPD) Pulau Ay dan Pulau Rhun terhadap sumber daya perikanan karang di Kepulauan Banda, Maluku, Indonesia. Metode yang digunakan untuk pengumpulan data yaitu Underwater Visual Census (UVC) dan Fish Length Estimation dengan bantuan peralatan SCUBA. Analisis data dilakukan dengan membandingkan data sekunder dan data primer yang meliputi kelimpahan, biomassa, status tropik dan komposisi ukuran ikan besar dan ikan kecil dari 10 famili ikan target dan ekonomis penting sebelum dan sesudah Pulau Ay dan Pulau Rhun dicadangkan sebagai KKP. Hasil penelitian menunjukan bahwa kelimpahan dan biomassa ikan karang secara temporal berfluktuasi sebelum dan sesudah Pulau Ay dan Pulau Rhun dicadangkan sebagai KKP, namun masih dalam kondisi melimpah dan tinggi. Status tropik dan komposisi ukuran ikan karang berubah-ubah sebelum dan sesudah pencadangan KKP, namun masih dalam kondisi seimbang antar kelompok tropik, ikan besar dan ikan kecil. Kesimpulan penelitian ini adalah pencadangan KKPD memberikan dampak positif terhadap sumber daya ikan karang di Pulau Ay dan Pulau Rhun.

Abstract

Lamun merupakan salah satu komunitas di intertidal Madasanger. Kawasan intertidal merupakan kawasan yang dinamis, dipengaruhi oleh perubahan pasang dan surut yang membuat kondisi lingkungannya tidak stabil sehingga menyebabkan perubahan terhadap habitat tempat hidup lamun. Penelitian ini bertujuan untuk mengkaji dinamika komunitas lamun di intertidal Madasanger pada musim kemarau. Pengamatan komunitas lamun dilakukan pada dua stasiun pengamatan sejajar garis pantai, yaitu zona atas dan zona bawah, pada musim kemarau (April). Keberadaan lamun memperlihatkan pola yang dinamis berdasarkan tutupan dan sebaran spasial lamun. Komunitas lamun terdiri atas lima genus, yaitu Cymodocea, Halodule, Halophila, Syringodium dan Thalassia, dengan tutupan rata-rata berkisar antara 36,5-75,67%. Selama 2014-2018, kondisi tutupan lamun tertinggi terjadi pada 2016. Kondisi lingkungan pada 2016 yang relatif stabil dengan curah hujan dan masukan air tawar yang relatif lebih rendah, merupakan kondisi lingkungan terbaik untuk kehidupan lamun, sehingga pertumbuhan lamun relatif lebih baik. Lamun hidup lebih baik pada substrat yang lebih dalam, terutama lamun Halodule dan Syringodium. Dinamika komunitas lamun di intertidal Madasanger diduga disebabkan oleh pergerakan substrat, yang diikuti dengan perubahan pola sebaran lamun selama lima tahun.

Abstract

West Aceh Regency has a coastline length of about 50.55 km, with an area of ??sea waters of around 80.88 km2. This condition is inseparable from its location facing directly into the Indian Ocean which is rich in fish. Rumpon, knowned as FADs, is an artificial tool that collects fish using atractors, such as coconut leaves, areca leaves and nipah leaves and other solid objects that serve as a lure for gathering fish. Drifting FADs are non-permanent FADs and are not equipped with anchors so they drift following the movement and direction of the current, while settled FADs are FADs equipped with anchors or weights. The aim of this study was to analyze the composition of species, the amount and weight of the fish caught. The study was conducted in January-July 2018, located in West Aceh waters. The data collected is in the form of primary data, where the collection uses the experimental fishing method. Furthermore, the data were analyzed statistically using the t test. Observations of the catch were carried out for up to 18 trips to traditional and raffia rope FADs. The variables observed in this study were species composition, number and weight of fish caught in both FADs. The results showed that traditional FADs obtained as many as 7,538 fish catches (61.5%) were more than 4,821 (38.5%) raffia rope FADs, with 7 species of fish being dominated by mackerel fish. This shows that traditional FADs are more effective than raffia rope FADs.
