Abstract

Penerapan kembali tradisi budaya mulung memberi dampak positif bagi habitat sumber daya perairan dikawasan peraiaran yang menjadi lokasi mulung. secara harafiah mulung terbagi dalam dua tahap pengelolaan. tahap pertama adalah prosesi adatia hading mulung pada tahapan ini kawasan peraiaran ditutup atau dilarang untuk sementara waktu dari aktivitas penagkapan atau pengambilan sumber daya melalui ritual adatia. pada tahap kedua adalah hoba mulung pada tahap ini diadakan prosesi adat pencabutan larangan sehingga kawasan mulung dapat dilakukan pengambilan atau penangkapan sumber daya perairan. interval waktu antara hading mulung dan hoba mulung memberikan kesempatan kepada alam untuk pulih. kondisi ini berdampak pada pemulihan habitat sehingga populasi sumber daya menjadi limpah. seturut melimpahnya sumber daya perairan seperti ikan berkorelasi positif terhadap volume penangkapan nelayan dan implikasinya pada saat penjualan, dalam hal ini pedagang ikan pun menerima manfaatnya dengan bertambah jumlah pendapatannya. metode survei digunakan untuk mengukur dampak mulung (konservasi habitat sumber daya periaran) terhadap peningkatan ekonomi masyarakat pesisir (nelayan dan pedagang) baranusa, menggambarkan pendapatan nelayan yaitu Rp. 6.400.000. selain itu pedagang juga mengalami peningkatan pendapatan sebulan berkisar Rp. 1.500.000 sampai dengan Rp. 6.000.000.

Abstract

The palm oil industry liquid waste is rich in organic materials and thus it can be used as media to grow Chlorella sp. This algae needs organic materials for growing, and it may decrease the organic material contents in the waste. To understand the best concentration of palm oil industry liquid waste to grow that algae, the chemical composition of the algae reared in different concentration of waste, and to understand the organic materials decrement in the waste, a study has been conducted in April – May  2019. There was a CRD applied. The waste was mixed with aquadest in   5 different concentration, namely    P1 (0%), P2 (15%), P3 (20%), P4 (25%), dan P5 (30%). Results shown that the best algae population was in the   P4 (4.64 x 106 cells/mL), the best biomass was in P3 (0.77 gr/L) in the 12nd day culture.  The P0 provide the best results on fat (12.5%) and carbohydrate (24%) but shown the lowest of protein (16%), DO (1.10 mg/L) and chlorophyll-a (0.140 mg/L) and provide the worst CO2 content (8.77 mg/l). P3 shown the highest content of protein (45%).   P4 shown the highest chlorophyll-a concentration (0.403 mg/L) and O2 concentration (9.94 mg/L) and the lowest CO2 (2.75 mg/l). The P4 also shown the best result in decreasing organic materials content. Nitrate reduced, from 14.3 mg/L into 3.1 mg/L, while Phosphate reduced, from    1.87 mg/L to 0.33 mg/L respectively. In all treatment, the water temperature ranged from 280C to 300C and the pH was   6.33 – 9.50.

Abstract

This research was conducted on 27 April-30 May 2019 at Tiram Beach, Karambia Ampek Beach and Gosong Beach, Padang Pariaman Regency, West Sumatra Province. This study aims to determine the relationship between sediment grain size and the number of turtle eggs. The method used in this research is purposive sampling. The sampling location is divided into 3 stations, each station is divided into 5 sampling points in order to obtain 15 sampling points, of which the fifteen sampling points are the usual nesting sites for turtles. Sediment samples were taken approximately 500 grams, put in a plastic bag, then labeled and then the sample was taken to the laboratory for analysis. The procedure for analyzing the sediment grains for sand and gravel fractions used the wet sieving method, for the sludge fraction was analyzed using the pipette method. The results from the wet sieving method and the pipette method were combined and the mean size (Mz) was obtained. Measurement data were analyzed using linear regression analysis, then correlation and regression analysis to determine the form of the relationship and the strength of the relationship between two or more variables. Sea turtles will lay eggs, namely the mean size ranges from 1.13-1.8 Ø. The coefficient of determination (R2) = 0.53 and the correlation coefficient r = 0.73. This means that the coefficient of determination shows the average diameter (mean size) affects 53% of the number of turtle eggs, while the other 47% is influenced by other factors, for example vegetation around the coast..

Abstract

Inland general waters fish resources in the East coast of Sumatra are thought to have experienced more fishing pressure due to non-selective use of fishing gear. Changes in the size of fish caught are one of the main indicators of fishing pressure. This study aims to determine the status of economically important fish resource utilization in the rivers of the eastern coast of Sumatra, by estimating the spawning potential ratio (SPR). The research was conducted in the rivers of the East Coast region of Sumatra, including the Kampar, Batanghari and Musi Rivers from January to December 2016. The research method was through field surveys and collecting sample fish through fishermen and fish collectors. The types of fish collected were baung, lais, pond, siam sepat, cork, and betok. The results of the analysis of the SPR value in the Kampar River, where baung fish only amounted to 1%, 2% lais and 11% pond. In the Batanghari River, the SPR values reached 16% and 37% for siam sepat and cork fish, while in Musi River, the SPR value for siam sepat fish was 4%, baung and betok were 2% respectively. Overall this value is far below the recommended threshold value of SPR (30-40%). The rate of exploitation of fish resources is also high, it can be seen from the proportion of mortality due to fishing to natural mortality (F / M) of 2 to 6 times the natural mortality rate, which indicates the status of fish stocks in the wild is in an alarming condition.

Abstract

Monsoon is one of the important atmospheric circulations of the global climate system, monsoon activity has a major influence on weather formation in the region in its path. Monsoon activity is often associated with the presence of synoptic disorders in the area in its path. Synoptic disorders involving the movement of rain slowed throughout the monsoon region. The monsoon pits on an annual cycle related to climate when dry and wet. During the dry season, winters occur on various continents with a mass of air in the atmosphere which results in cold and dry, while when it is wet, it affects the summer with moist air. The Java Sea is an area of 310,000 Km2 which is located only 220 miles from the island of Borneo and the north coast of Java covers the archipelago. The geographical position of the Java Sea is in the area where the interaction is occurring - the atmosphere in the Java Sea is becoming more dynamic. Research Objectives to analyze the influence of rainfall in the Java Sea spatially and temporally. The data used are wind re-analysis of zone and meridional data (ftp.cdc.noaa.gov/ Data set /) from 1986 to 2017, for rainfall data at Tegal, Semarang and Surabaya Meteorological Stations 1986-2017. Spatial and temporal monsoon wind patterns are more dominant and beneficial to the variability of rainfall in the Java Sea. This condition can be seen in the type of monsoonal rain letter U or V with one peak of rain in December January and February (DJF) with the beginning of the rainy season in December in June July August (JJA) peak of the dry season and dry season beginning in June.

Abstract

One of the methods used in intensive cultivation on limited land is the use of a recirculation system with a certain type of filter. This study aims to find the best type of inorganic filter in the cultivation of recirculation systems. This research was conducted from May to August 2019. The materials used were selais fish with a length of 6.8-7.8 cm and a weight of 1.07-2.36 g and fish feed in the form of commercial pellets PF 800. 60x40x40 cm and 60 liter water volume. The method used was an experimental method with one-factor completely randomized design (CRD), namely the type of filter and five levels of treatment (filter type), namely dacron, bioball, gravel, charcoal and zeolite. The parameters measured were the quality of the water in the maintenance medium and the blood glucose levels of the fish. The results showed that the use of different types of filters in the recirculation system had an effect on water quality and blood glucose levels in O. hypopthalmus fish. The results of temperature measurements duringthe study showed that the value of the temperature range was not much different in all treatments, namely in the range, pH and dissolved oxygen were not much different between treatments, namely 26.5 - 29.20C, 7-8, and 4.0- 6.5 mg / L. While the lowest levels of NH3, NO3 and NO2 are found in the bioball filter, namely 0.05 mg / L, 0.65 mg / L and 0.33 mg / L. The treatment with the lowest stress level was the bioball filter, indicated by a blood glucose level of 67.25 mg / dL. Based on the results of the study, it can be concluded that the use of bioball filters in the recirculation system for rearing tilapia (O. hypopthalmus) provides the best results in water quality and reduces stress levels of fish.

Abstract

Many community activities utilize the Kampar River watershed in the Pangkalan Kerinci Bridge area such as ports, restaurants, cultivation of floating net cages, and sanitary activities. These various activities will affect the water quality there. Therefore monitoring water quality in the region needs to be done to see the quality of its waters which refers to the calculation of the Pollution Index and determine the management of these watersheds to be suitable for aquaculture activities. This research was conducted in November 2017 - February 2018. The survey included measuring water samples and observing the condition of the border and the activities of the community around the river water bodies. Ex situ analysis was conducted at the Laboratory of Ecology and Environmental Management of the Water Faculty of Fisheries and Maritime Affairs, University of Riau. The parameters observed were TSS, DO, COD, BOD, pH, and Total P. Water sample measurements were carried out once at 10 am during sunny weather conditions. There are three sampling points, namely: the area under the Pangkalan Kerinci Bridge (Station I); river wash area 1 (Station II); and river rinse area 2 (Station III). From the results, it is known that overall the Kampar River area around the Pangkalan Kerinci Bridge is in the light-polluted category. Based on the IP value, the condition of the waters in this region can be sorted from high to low polluted that is sequentiallyStation I (2.27), Station II (1.53), and Station III (1.51). It is known that pollutants are organic materials that come from community activities around water bodies. This is evidenced by the high BOD value in water samples. Handling is needed for organic wastes discharged in water bodies to be able to improve the quality of these waters to make them suitable for aquaculture activities.
