Abstract

Abstract. Yellowfin tuna (Thunnus albacares) is a large pelagic fish that have high economic value and inhabits the Moluccas Sea, Indonesia. Tuna catches in the Moluccas sea was very high and might decrease the yellowfin tuna population in this region. The research on population genetic of yellowfin tuna is fundamental to answer the problem. This information can be used as baseline data for future management, utilization, and basis of genetic conservation. The objective of this research was to infer the genetic population structure of two populations (North Maluku and Ambon) in the Moluccas Sea, Indonesia. In total, 41 tissue samples from pectoral fins of yellowfin tuna were collected in this study (North Maluku 33 samples and Ambon 8 samples). The results showed that genetic distances were low between the two populations. Additionally, the comparison of genetic distance between the Moluccas population and Indian Ocean waters also showed no significant differences. The Fst analysis showed the high gene flow between these two populations. Furthermore, haplotype network analysis showed that these two populations were the panmixia population. The overall result showed that no refraction genetic in the yellowfin tuna population from two populations in the Moluccas Sea.Keywords: Haplotype, genetic distance, Moluccas Sea, index fixation analysis, yellowfin tuna, population genetic structure. Abstrak.

Abstract. The objective of the research is to analyze the frequency of Tropical Cyclone between 2007-2011 and to analyze Typhoon Choi-wan and Typhoon Nida. Geographical location of the research is between 30-195E, 15-180W dan 60-60N.  Tropical cyclone is a cyclonic originates from tropical oceans and is driven principally by heat transfer from the ocean. Tropical region is an area that receives more intensive solar radiation, so that sea surface temperature is relatively higher then in the pole. High sea surface temperature drive then a low pressure to form which can lead to tropical cyclone that begins with a tropical disturbance and tropical depression, tropical storms and then tropical cyclones. Frequencies of Tropical cyclone occurrences over northern hemisphere are 320 events which are higher than frequencies of tropical cyclone over southern hemisphere, i.e., 132 occasions. Tropical cyclones are analogues to Carnot heat engines. The size of the energy can be expressed as the total entropy s per unit of air mass and its mechanical energy. Carnot cycle is a closed process. During the cycle entropy is produce near sea level where the sea surface temperature is warm and it will be loss near the top of the clouds where the temperature is cold. Carnot cycle in tropical cyclones can produce mechanical energy. Typhoon Choi-wan and Nida produced mechanical energy of 14790.72 J/kg and 13297.28 J/kg, respectively.Keywords : Carnot cycle; Mechanical energy; Tropical cycloneAbstrak. Tujuan dari penelitian ini adalah menganalisis frekuensi kejadian siklon tropis antara tahun 2007-2011 dan menganalisis Topan Choi-wan dan Topan Nida. Domain geografi pada penelitian ini yaitu 30-195˚BT, 15-180˚BB dan 60-60˚LU. Siklon tropis adalah gerakan siklonik yang berasal dari lautan tropik dan digerakkan oleh transfer panas dari lautan. Daerah tropika merupakan daerah yang lebih intensif menerima radiasi matahari, sehingga suhu permukaan laut di daerah tropika lebih tinggi daripada di daerah kutub. Ketika suhu permukaan laut tinggi maka terbentuk pusat tekanan rendah yang dapat memicu terjadinya siklon tropis yang dimulai dengan gangguan tropis lalu depresi tropis, badai tropis selanjutnya terjadi siklon tropis. Frekuensi kejadian siklon tropis di BBU adalah 320 kejadian lebih besar daripada frekuensi kejadian siklon tropis di BBS yaitu 132 siklon tropis. Siklon tropis dianalogikan sebagai mesin Carnot. Ukuran dari energi dapat dihitung melalui total entropi s per unit masa udara dan energi mekanik dari siklon tersebut. Siklus Carnot merupakan proses tertutup. Selama siklus tersebut berlangsung entropi diperoleh dekat permukaan laut dengan suhu yang hangat, dan entropi dapat hilang di dekat awan bagian atas karena suhu awan semakin dingin. Siklus Carnot pada siklon tropis dapat menghasilkan energi mekanik. Energi mekanik siklon tropis Choi-wan yaitu 14790,72 J/kg dan siklon tropis Nida yaitu 13297,28 J/kg.Kata kunci : Siklus Carnot; Energi mekanik; Siklon tropis

Abstract

Seagrass ecosystems have an essential function as a feeding, spawning and nursery areas for various marine biota, etc. There are threats to the sustainability of seagrass ecosystems' biodiversity, one of which is the dumping of garbage into the sea, which causes damage to coastal ecosystems. This study aimed to determine the species and cover of seagrass ecosystems and the type and density of marine debris in seagrass ecosystems in the waters of small islands of Tanjungpinang City. There are three stations: Dompak Island, Penyengat Island, and Los Island. This research was conducted in May-June 2023. Seagrass cover data was collected using the line transect method with a quadrat transect of 50 cm x 50 cm to observe the species and cover. Data collection on marine debris in the seagrass ecosystem was taken on transects with an area of 100 m x 100 m. Marine debris obtained is then grouped by type to calculate density and weight. The types of seagrasses found include Enhalus acoroides, Thalassia hemprichii, Cymodocea serrulata, Cymodocea rotundata, Halodule uninervis, Halodule pinifolia, Halophila ovalis, and Syringodium isoetifolium. The highest total seagrass cover is found on Los Island, with a value of 25.81% classified as poor with a sparse cover category. The types of marine debris found are plastic, glass, rubber, wood, and its derivatives. According to the number of pieces, the highest density of marine debris is plastic waste, resulting in 0.0079 items/m2, and the weight density is 0.0528 grams/m2 found at Los Island.Keywords:biodiversitydebrisplasticseagrasssmall island
