Granulometric study is considered as a tool to predict sediment formation process in an aquatic environment. This paper discusses brief assessment of granulometri studies on seagrass and coral reef areas in Indonesia by collecting samples at Pari Island waters. Sediment samples were taken in May 2008 near the coral reefs and seagrass area in the cluster of Pari Island waters, Seribu Islands, Jakarta. The wet sieving method was done to separate the sediment samples based on grain size. Statistical analysis i.e., mean, sorting, skewness, and kurtosis at both locations showed a considerably complex energy works on the sediment distribution in these locations.Keywords: granulometry; sediment; coral reef; seagrass Abstrak.

Zamani, Neviaty Batubara, Irmanida Date A point or period of time associated with an event in the lifecycle of the resource 2014-01-01 Description An account of the resource The aim of the present study was to analyse the peel waste of Xylocarpus granatum fruits as potential source of tyrosinase inhibitors. Dried peel samples were ground to yield a powder (simplicia). Subsequently, they were extracted with organic solvents of distinct polarity levels, namely n-hexane (non-polar), chloroform (semi-polar) and methanol (polar) by use of the single-maceration method. Inhibitory effects on tyrosinase activity (monophenolase) and DOPA auto-oxidation (diphenolase) were determined in bioassays. Assays with the methanol extract revealed IC50 values of 784.87 μg mL-1 (monophenolase) and of 1176.66 μg mL-1 (diphenolase), respectively. In contrast, n-hexane and chloroform extracts showed no activity. These results indicate that the methanolic fruit peel extract contained tyrosinase-inhibiting compounds, such as flavonoids, tannins and saponins, whereas the n-hexane and chloroform extracts yielded alkaloids, steroids and triterpenoids without tyrosinase-inhibiting activity. The phenolic compounds had a strong effect on the tyrosinase enzymes, inhibiting monophenolases by 97% and diphenolases by 96%, with a positive correlation between the total phenolic content and the inhibition rate in both activities.

Genetic diversity information of Gobiidae is needed as a basis for management of its culture or conservation efforts. Mean while, the stability development of the paired organs in animals is closely related to the level of their genetic diversity. In this regard, a study has been conducted to determine of bilateral symmetry characteristics of marble gobies from Jenderal Soedirman reservoir of Banjarnegara and Rawapening Swamp of Salatiga. A survey method was used with purposive sampling technique. The observed variables were abnormalities and meristic bilateral characters. The characters including the number of soft rays on pectoral fins and pelvic fins, and the number of scales on lateral lines. The results showed that both marble gobies from Jenderal Soedirman Reservoir and Rawapening Swamp did not show abnormalities. However, their bilateral meristic characters had been fluctuated, especially for pectoral fins and lateral lines; whereas pelvic fins seem to be symmetry. According to their observed bilateral symmetry characters, in general, it could be concluded that marble gobies from Jenderal Soedirman Reservoir had a better genetic diversity compare to those from Rawapening Swamp. Therefore, it can be used as local genetic resources.Key words.

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             Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/depik/article/view/974 10.13170/depik.2.3.974 Language A language of the resource eng Publisher An entity responsible for making the resource available Faculty of Marine and Fisheries, Syiah Kuala University Relation A related resource http://jurnal.unsyiah.ac.id/depik/article/view/974/918 Source A related resource from which the described resource is derived DEPIK; Vol 2, No 3: September - December 2013 2089-7790 Title A name given to the resource Kajian beberapa karakteristik siklon tropis (kasus topan Choi-wan dan Nida di lautan Pasifik Utara bagian barat) Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
