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

Ovens or artificial/mechanical drying devices are tools used in educational and research activities in laboratories that function for sterilization, drying, and storing samples or processed products. This research modifies the tangkring oven with an innovative use of electricity. The background of the study is because there is no drying device and small sample storage with a small number of samples. The modification aims to make a replacement device as a dryer and sample storage in the laboratory. This study used an experimental method, and the data were analyzed descriptively. The oven that has been modified using a tangkring oven has an inner dimension of length =36 cm; width=36 cm; height =32 cm, heat source from 150-watt halogen lamps totaling two pieces, and a 12 cm diameter fan, the outer part of the tool has a length = 42.5 cm; width = 38 cm; height = 38 cm, equipped with legs and four wheels with a height = 85 cm. Temperature testing was carried out on each shelf with a thermometer as a temperature measuring instrument, with a temperature range of 30-60⁰C. The time required to reach a constant temperature is 0.5 to 20 minutes, and the temperature difference between the regulated temperature and the temperature achieved on the tool ±2ºC shows the results obtained are still within tolerance, the error value is still within tolerance ±5% indicates the results of the tool system performance is not disturbed. From the observations made, it is concluded that the modified tangkring oven can be used as a drying device and sample storage with a faster time and using limited samples for laboratory activities.

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.

Abstract

African catfish (Clarias gariepinus) is a freshwater fish that has the advantages of fast growth, high economic value, adaptability to environmental changes, and easy marketing. This study aims to analyze the growth rate, survival rate, and nutritional content of African catfish after being treated with photoperiod and different types of feed. The research was conducted from September to December 2022, at the Fish Health Laboratory at the Matauli Marine and Fishery College, Central Tapanuli. The method used is an experimental method by applying a Completely Randomized Design Factorial, two factors, and three replications. The first factor is the photoperiod (B), namely natural (B1), 18 hours dark 6 hours light (B2), 24 hours dark (B3), and the second factor is the type of feed (A), commercial feed (A1) and maggot (A2). The test fish used were obtained from the Central Tapanuli Fish Cultivation Seed Center measuring 16.01±0.02 cm and weighing 30.00 ± 0.00 g for a total of 126 individuals. Fish were reared for four weeks in rearing containers with a stocking density of 1 fish/10L. Feed is given four times a day, namely at 06.00, 12.00, 18.00, and 24.00 ad satiation. The results showed that photoperiod manipulation and different types of feed affected the growth and survival of African catfish fry (p<0.05). The combination of photoperiod 24 hours dark and maggot feed (B3A2) gave the best results on absolute weight growth of 22.70g, absolute length of 2.56 cm, a specific growth rate of 2.01%/day, a survival rate of 100%, and nutritional content of fish meat such as protein of 18.97%, 8.68% fat, 0.73% fiber, 1.54% ash, and 80.26% water.

Abstract

This research was conducted in July 2022 in Sinaboi District, Rokan Hilir Regency. This study aimed to analyze the sustainability status and attributes strongly influencing the sustainable management of four-finger threadfin (Eleutheronema tetradactylum) in Sinaboi District, Rokan Hilir Regency. The method used in this research is the survey method. Data sources were collected from primary data and secondary data. The purposive sampling technique selected nine respondents who met specific criteria. The data obtained were analyzed with RAPFISH to explain the ecological, economic, social, technological, and institutional dimensions that include sustainability attributes through several analyses, including Multidimensional Scaling (MDS) and sensitivity analysis (leverage analysis). The results of the Multidimensional Scaling (MDS) analysis showed that the sustainability index in the ecological dimension with a value of 61.71 and the economic size with a value of 52.12, which has a reasonably sustainable status, as well as in the social dimension with a value of 50.94, the technological extent with a value of 48.81 and the institutional size with a value of 50.40 has a less sustainable status. 9 leverage attributes are sensitive and affect the value of sustainability in the results of sensitivity analysis (leverage analysis) for each dimension. Influential details need to be considered to increase the sustainability value of four-finger threadfin in Sinaboi District.
