Abstract

The quality of the catch can be seen from the fish storage container used to maintain its temperature. An insulated storage area can maintain ice resistance during the operation of fishing gear, as well as during the transportation of the catch to the fish landing site. Generally, fishermen use fish storage containers made of fiber with insulation in the form of polyurethane. Some fish storage containers are made from polystyrene-insulated styrofoam. This research aims to determine how optimal cooling is using coconut fiber and sugar cane bagasse insulation. The method used in this research was an experimental method using a Completely Randomized Design (CRD) with one control (Styrofoam cooler box), two treatments (Coconut fiber insulated cooler box and sugarcane bagasse), and three repetitions. The dimensions of the coolbox are the same as those on the market, namely 42 cm x 26 cm x 23 cm and a thickness of 2 cm. The lowest temperature of the coolbox made from coconut fiber insulation, 17.7 °C, was reached after the 70th minute. The bagasse was only able to reach the lowest temperature of 19.4°C, achieved in the 60th minute. Temperature stability in the coconut fiber coolbox reached 2 hours 10 minutes (130 minutes) from 80-200 minutes, while the bagasse coolbox reached 3 hours 40 minutes (220 minutes) from 70-280 minutes.

Abstract

One of the tourism areas in Dumai City is Medang Kampai District, which is a coastal area with an area of ​​373.00 km2. Coastal areas are always used for human activities, one of which is coastal ecotourism which is a coastal tourism activity developed with a conservation approach and utilizing the characteristics of coastal resources as tourist destinations. Medang Kampai District has many coastal ecotourism areas, including Pulai Humpback Beach, Pesona Alam Mundam Beach, Aulia Dumai Beach, Marina Puak Beach, Koneng Beach, Acacia Indah Guntung Beach and Legenda Beach. The method used in this study is a survey method, which was set at 5 (five) research locations, namely Pesona Alam Mundam Beach (Station I), Aulia Dumai Beach (Station II), Koneng Beach (Station III), Acacia Indah Guntung Beach (Station IV), and Legenda Beach (Station V). Based on the results of data processing using DSAS software, the results showed that the coast in the Medang Kampai sub-district was dominated by abrasion with an average abrasion rate of -2.96 m/year. The highest abrasion occurred at Acacia Indah Guntung Beach, followed by Pesona Alam Mundam Beach, Legenda Beach, Aulia Dumai Beach, and Koneng Beach. The impact on the coastal ecotourism area due to abrasion is that several facilities and infrastructure have been damaged and there has been a reduction in the area of ​​coastal ecotourism which is thought to cause a reduction in the capacity of visitors while at the same time directly impacting the economy of the local community whose livelihoods depend on coastal ecotourism.

Abstract

Mangrove crab (Scylla serrata) catching activities generally use collapsible traps. Folding traps can be operated using bait and not using bait, but the catch is less effective if it does not use bait. The purpose of this study was to determine the effect of using different types of bait (fresh stingray, salted stingray, fresh eel, and salted eel) on the catch of Mangrove crab in Kampung Laut waters. The material of this research is the catch of mangrove crabs using fresh stingrays, salted stingrays, fresh eels, and salted eels as bait. The research method used is experimental fishing. The collected data includes environmental parameters, the number of catches, and the trap size. Data analysis used a Completely Randomized Design (CRD) and Duncan's follow-up test. The results showed that the different types of bait used affected the number of catches, catch weight, and catch size. This study concludes that the catch of mangrove crabs with salted stingray bait gets the most catches, namely 16 fish, and on salted eel bait gets 13 catches, while in fresh stingray bait treatment, it only gets seven catches and on fresh eel gets five catches.
