Abstract

Shells, a by-product of the sea urchin processing industry. The proportion of shells up to 85% is more widely used as a feed additive. This research aims to extract collagen from sea urchin shells using acetic and lactic acid (0.25-0.5 M). The acid-soluble collagen was then analyzed for its functional groups using the Fourier transform spectroscopy (FTIR) method. The higher the acid concentration used in extraction, the higher the yield of collagen produced. The highest collagen yield was obtained at a concentration of 0.5 M acetic acid. FTIR analysis of acid-soluble collagen showed functional of amide A (3351.64), B (2964.00), I (1663.25), II (1558.16), and III (1244.97) (cm-1). The results of functional group identification show that the acid-soluble collagen from sea urchin shells is in accordance with collagen standards.

Abstract

This article aims to provide a new perspective and paradigm in sustainable fisheries management by introducing and integrating sharia principles and approaches into the fisheries bioeconomic model. The initial model is carried out by introducing ZIS parameters into the Gordon-Schaefer fisheries bioeconomic model. The amount of ZIS can provide encouragement to build and develop a sustainable sharia fisheries bioeconomic management model. Factors that influence the success of fishing gear (q) to be able to catch fish, the ability of the environmental carrying capacity (K) to be able to maintain fish reproduction and growth, and the ability of the fish themselves to grow and develop in achieving a certain biomass (r) are something that is essentially desired as a gift from the Almighty on the basis of the efforts of His servants to fulfil the ZIS command. In addition, the income of His servants (fishermen) which is influenced by the price (p) of fish and the efficiency of the cost per unit of catch (c) that must be spent to obtain fish is an inseparable part of the existence of income which is also a gift from Allah. The five parameters of the sharia bioeconomic of fisheries (r, q, K, p, c) which are influenced by the presence of the ZIS factor are the fortune and way of Allah SWT to bestow blessings, gifts, and welfare to His servants (fishermen) who have fulfilled ZIS. This sustainable sharia bioeconomic management model of fisheries is based on the paradigm and perspective of the community (fishermen) in carrying out fishing through the fulfilment of ZIS maximally and sustainably which is carried out by always hoping for the pleasure and blessings of Allah SWT, it is hoped that it can change the lives, lives and livelihoods of the fishing community.

Abstract

 Pesawaran Regency is a buffer zone for the capital city of Lampung Province which has a fairly wide and potential coastal area. With a variety of rich biodiversity and environmental services provided, coastal and marine resources have high economic and ecological value. In order to ensure the sustainability of these resources, their management must be carried out in a planned and integrated manner and be able to provide the maximum benefit to all stakeholders, especially coastal communities, and minimize impacts and conflicts that could potentially occur. The method used in this study is literature study. The results show that coastal communities in Pesawaran Regency have a fairly active role in the management of coastal areas.

Abstract

The beach is an area that often experiences changes in shape that can occur quickly or slowly depending on those who influence it, both due to natural and artificial factors. Tabuhan Island is one of the islands that has the problem of shoreline changes. This study aims to determine the physical conditions of hydrooceanography and changes in the coastline of Tabuhan Island. Hydrooceanographic physical parameters include tides, currents, winds, waves and Total Suspended Solids (TSS). The study of changes in the coastline of Tabuhan Island uses the overlay method using Google Earth images in 2006, 2011, 2016 and 2021. The overlay method is a method of overlapping images from the old to the newest. The results show the waters of Tabuhan Island have a mixed tidal type with a double daily trend, the current speed ranges from 0.2760 m/s to 0.9023 m/s from north to south and the wind has a speed of 0-17 knots dominantly from south to north and southeast to northwest. The waves have a maximum height of 2.6 m and a minimum of 0.01 m and the highest Total Suspended Solid (TSS) value is 198.9 mg/L and a minimum of 110.3 mg/L. The results of the study show the area Tabuhan Island has reduced its area from 67,313.4 m² to 50,028 m²mwith an annual evenly of 850.9 m² in the period 2006 – 2021. The abrasion value that occurs is 22,423.3 m² happening in south and west and the accretion is 5,128.9 m² happening in the north Tabuhan Islands.

Abstract

Fishing Gear is equipment used by fishermen to catch fish and other marine animals. The operation of the fishing gear itself is not always alone, some fishermen use fishing aids to increase the effectiveness and efficiency of fishing activities. Some types of Fishing aids commonly used by fishermen are lamps and fish aggregating devices (FADs) used to collect fish and power blocks/axles, or line haulers used by fishermen to facilitate the operation of the fishing gear. This study aims to find out what fishing gear and fishing aids are in Kendari and analyze their compliance with existing regulations. The research activities were carried out for 2 months, namely from November to December 2023 at the Kendari Fisheries Port. The type of data collected is qualitative data including construction data from each API in Kendari through direct observation. The data collected is then analyzed descriptively. Based on the data obtained, the types of Fishing Gear used by vessels based at the Kendari PPS are 5 (five) fishing gears, consisting of Tuna Hand Line, Huhate, Purse Seine, Hand Line, Squid Fishing. This fishing gear is an active fishing gear. Fishing aids used by fishermen at PPS Kendari include LED lights, Pakurung and fish aggregating devices. There are still violations related to the use and operation of fishing gear (purse seines), as well as the installation of fish aggregating devices. To avoid violations of the use of fishing gear and fishing aids, currently there is still a need for supervisory officers and equipment support using technology.

Abstract

Dompak Island is a mangrove area that has great potential in the Tanjungpinang urban area. However, the area of mangrove land decreases every year due to excessive mangrove logging. So a mangrove restoration program was formed by the CarboEthics Foundation. Apart from having an ecological impact, it also has an economic impact on society. The aim of the research is to estimate community income before and after the mangrove restoration program on Dompak Island. This research was conducted in March-April 2024 in the Tanjung Siambang Tourism Village which is located on Dompa Island. The research uses data analysis by calculating income. The results of the research are that the average income for the restoration worker program is IDR 52,356,333. The percentage change in income is an average of 60%.

Abstract

This study aims to determine the effect of the addition of Papuan red fruit oil supplements (Pandanus conoideus) as a result of red fruit extraction, on the development of ovaries and the length of maturation time of mangrove crab ovaries (Scylla serrata). Red fruit (Pandanus conoideus) is an endemic Papuan plant that is believed to cure several diseases and can be used as a supplement because it contains active compounds including fatty acids in the form of triglycerides and antioxidant compounds such as beta-carotene and tocopherols. Experiment with feeding fresh feed to Mangrove Crab broodstock, weighing 400-500 g/head. The experiment was conducted using a Complete Random Design with three feed compositions and three individuals as replicates. Feed A (control): Decapterus sp.100 g; Feed B : Decapterus sp. 23 g, 40 g Shelled Squid, and 37 g Red Fruit Oil; Feed C: Decapterus sp fish 41 g, squid shell 24 g, and Red Fruit Oil 35 g. The parent maintenance container uses a transparent plastic container with water circulation (waterflow). The parameters measured were the length of time to reach ovarian maturity and the number of larvae produced by mangrove crabs (Scylla serrata). The data was analyzed with INOVA. The results of the study showed that the mother crab fed Red Fruit Oil supplement had a longer time to mature ovary faster than the mother crab fed without Red Fruit Oil.
