Nutrient distribution models and flow patterns in Coastal Waters and Small Islands, Tanjungpinang City, Indonesia
No full textResearch has been done on the model of nutrient distribution and current pattern in coastal water of Tanjungpinang City. The research objective was to develop a model of nutrient distribution and current patterns in coastal waters and small islands as an effort to manage the eutofication of coastal waters and small islands in the archipelago. Determining the location of the observations was done by purposive sampling at high tide and low tide at several predetermined research stations. The results showed the nutrient distribution model in the waters of Tanjungpinang Bay, a different distribution pattern compared to the waters of the Dompak Strait, with the distribution of nutrients from the yield model at low tide and at high tide shows the same pattern, which tends to decrease offshore and high in some coastal locations. around the waters of the Sei. Carang estuary which is connected to the waters of Tanjungpinang Bay. The pattern of currents during the highest tide is bandage and full moon in coastal waters and small islands in the area of Tanjungpinang City, which shows that the inlet flows from the west of the waters, then exits towards the north into open water. However, part of the water mass in the presence of small islands around it becomes fragmented causing a turn to the south of the coastal waters of the city of Tanjungpinang, with a maximum current speed of 1.1 m/s

Estimation maximum sustainable of skipjack fish in the waters of Ternate Island
No full textThis study aims to determine the productivity of skipjack fish in the waters of Ternate Island. Optimum efforts that produce maximum catch and still maintain stock biomass in equilibrium conditions. Fishing activities are activities carried out to get several catches, to meet demand as a source of food. The demand causes an economic cycle where profits and losses will occur so that fishing activities will be carried out by increasing fish production to achieve maximum profits by fishing businesses. Production and effort data obtained from the Ternate Archipelago Fisheries Port (PPN) and related agencies in the past 5 years (2012-2016) experienced fluctuations. Catches per unit of capture effort (CPUE), reflecting the comparison between the catch and the effort spent. The catch in principle is the output of the fishing activity, while the effort that is needed in principle is input from the fishing activity. CPUE calculations must be standardized for fishing gear first because based on production data there is more than one fishing gear commonly used to catch skipjack fish. It can be seen that in 2013 and 2014 the level of utilization of skipjack fish resources was in the optimal utilization category because the range of skipjack fish production was between 74% to 82%, whereas in 2012 and 2016 the use of skipjack fish in a year was 65% smaller so it was categorized underexploited and in 2015 the level of utilization of skipjack fish resources has experienced overfishing because it has passed the maximum limit that has been set which is 4,252,461.31 tons/year

Penelitian dilakukan pada bulan Oktober-Desember 2019. Penentuan stasiun ditentukan dengan metode purposive sampling, terdapat 5 stasiun berdasarkan perbedaan karakteristik dari setiap stasiun ditemukannya makroalga. Pengambilan sampel makroalga dilakukan pada setiap stasiun pengamatan dengan menggunakan transek garis. Penempatan transek garis pada setiap stasiun untuk pengambilan makroalga sebanyak 3 sepanjang 50 m, penetapan plot pertama dilakukan berdasarkan titik pertama kali ditemukannya makroalga yang ditarik tegak lurus terhadap garis pantai dengan jarak antar garis yaitu 30 m. Hasil penelitian ditemukan 8 spesies makroalga (rumput laut) dari 3 Divisi yaitu Caulerpa serrulate, Halimeda opuntia, Chaetomorpha crassa, Sargassum polycystum, Sargassum cristaefolium, Padina australis, Gracilaria salicornia, Galaxaura fastigiate. Pola sebaran jenis makroalga di perairan Malang Rapat berkisar antara -4,212-1,708 dengan kategori mengelompok pada stasiun 1 dan merata pada stasiun 2, 3, 4, 5. Setiap stasiun didominansi oleh alga cokelat genus Sargassum. Faktor yang mempengaruhi distribusi makroalga di perairan intertidal adalah cahaya, suhu, pH, pergerakan air, dan jenis substrat. Semua parameter kualitas air yang telah diukur memenuhi syarat bagi pertumbuhan optimum rumput laut.This study aims to determine the distribution patterns, and environmental parameters of macro algae waters in the Intertidal Zone of Malang Rapat waters Gunung Kijang District, Bintan Regency. This research was conducted in October-December 2019. The purposive sampling method was applied to 5 research station based on the different characteristics of each station that found macro algae. Macro algae sampling was carried out at each observation station using line transects. Placing transect lines at every station to collect 3 macro algae along 50 m, the determination of the first plot is based on the first point of finding macro algae that are drawn perpendicular to the coastline with a distance between the lines of 30 m. The results found 8 species of macro algae (seaweed) from 3 divisions namely Caulerpa serrulate, Halimeda opuntia, Chaetomorpha crassa, Sargassum polycystum, Sargassum cristaefolium, Padina australis, Gracilaria salicornia, Galaxaura fastigiate. Distribution patterns of macro algae in the waters of Malang Rapat between -4,212 - 1,708 with the category grouping at station 1 and equivalent at station 2, 3, 4, 5. Each station is dominated by brown algae with the genus Sargassum. Factors affecting the distribution of macro algae in intertidal zone are lights, temperature, pH, current and substrate. All water quality parameters fulfilled the optimum growth requirements of seaweed
Optimization formula of instant powder functional drinks from Brunok (Acaudina molpadioides) using foam drying method
No full textThis study aims to obtain the right formulation in terms of nutritional and organoleptic value of Brunok instant powder drink. The optimized factor is the amount of Brunok extract used for the manufacture of instant powder drinks with an additional 1% emulsifier and 10% maltodextrin. Making instant powder drinks using the foam mat drying method using an oven with a low temperature setting of 70-80 °C for 15-20 minutes. The use of low temperature is intended to maintain the functional value of the Brunok instant powder drink which is beneficial for health. Based on the trial and error test, 3 instant powder drink formulations were obtained, namely F111, F211 and F311, by means of the hedonic test the preferred formulation for panelists was the F211 formula. The characteristics of the selected powder drink are water content 4.91%, fat 1.75%, protein 2.47%, ash content 0.45% carbohydrate content 90.43% and ALT 7.0x101 colony/g
The use of probiotic for growth and survival of milkfish (Chanos chanos Forskal)
No full textMilkfish cultivation in Muna Regency has not yet developed optimally, allegedly due to poor water circulation. Internal solution that can be done is the use of probiotics in water maintenance media. The aim of this study was to determine the effect of adding proiotics to media water with different doses on the growth and survival of milkfish (Chanos chanos Forskal), carried out in May to June 2019 at the Gonangkalo Beach Fish Seed Center (BBIP), Gonebalano, Duruka District, Muna Regency. The study used a complete randomized design (CRD) with three probiotics namely A 10 mL treatment per container, 20 mL treatment B per container and 30 mL C treatment per container. Data were analyzed using Variance Analysis (ANOVA) at 95% confidence level (α 0.05). The results showed that the highest daily growth rate was obtained in Treatment B at 5.84±0.16% per day followed by Treatment A at 5.71±0.23% per day and Treatment C at 5.42±0.10% per day. The highest absolute growth of milkfish was obtained in Treatment B at 8.24±0.28 g per individual and the lowest was in Treatment C at 7.95±0.0.33 g per individual, Continuation in Treatment A and B 83.33±5,77%, while in Treatment C 80.00±10.00%. Analysis of variance (α 0.05) showed that the use of probiotics with different doses significantly affected absolute growth (p>0.011) but did not significantly affect the daily growth rate (p<0.063) and survival (p<0.850) of milkfis
