Abstract

The fisheries sector is one of the main driver of the national economy. One area of Indonesia that has fishery potential that can be developed is Paciran District, Lamongan Regency, East Java Province. This study was conducted in Kranji Village, which is located in Paciran District and has great pelagic fishery potential. The purpose of this study is to analyze the determination of superior fish commodities from the capture fisheries sector in Kranji Village. The determination of the leading commodities is carried out based on the LQ (Location Quotient) analysis method. The fluctuation of the catch in Kranji Village is affected by various aspects such as natural conditions, the number of fishing gear and government regulations. The fishing season in Kranji Village is divided into: (1) Tuna (Thunnus sp.) season which occurs from October to April with 15 to 20 trips per month; and (2) Goldstripe Sardinella (Sardinella gibbosa) season from May to September with 7 to 12 trips per month. Fishing gear in Kranji Village consists of purse sein, gill nets, cob nets, waring and mini trawlers. This study found that LQ value >1 for 12 fishes species: Bali Sardinella, Goldstripe Sardinella, Torpedo Scad, Longtail Tuna, Eastern Little Tun, Narrow-barred Spanish Mackerel, Giant Fish, Black Pomfret, Dorab Wolf Hearing, Orange-spotted Spinefoot (1.065), Other Fishes (1.057), and Short-bodied Mackerel (1.007). The results indicate that 12 fishes species have a comparative advantage and increasing income and contribution to the economy of Kranji Village.

Abstract

Seagrass is an ecosystem that has an important role as nursery and spawning ground in the life cycle in the sea. Increased human activity and climate change are feared to damage seagrass ecosystems so it is important to maintain their sustainability. This study aims to find out the composition of species, density and coverage of seagrass at Tunggul Beach, Paciran, Lamongan. This research was conducted on August until October 2020 by applying purposive sampling method as the basis for determining location point at 2 stations, with 3 substations at each station with transect line along 100 m. Seagrass data retrieval method using transect quadrant 50 x 50 cm to observe the coverage and calculate seagrass stand. The results showed the type of seagrass found on Tunggul Beach are two species, Thalassia hemprichii and Enhalus acroides. Seagrass density value at station 1 is rather tight with a density value of 92.48% and at station 2 is rare with a value of 73.09%. The percentage of seagrass coverage at station 1 indicates a solid category with a coverage value of 54.92% and in the station 2 shows a medium coverage category with a value of 31.25%.

Abstract

Fisheries productivity plays an important role in national development. The potential of fisheries in Indonesia is quite large so that many coastal communities depend on their lives from fishing activities. East Java province has a fishery area that is quite potential with the availability of considerable human resources, one of them is Lamongan. This research was conducted in Fish Auction Site (Tempat Pelelangan Ikan, TPI) Kranji, Lamongan. The purpose of this study is to find out the productivity value of purse seine fisheries in TPI Kranji based on the size of the ship and the fishing trip. This research was conducted by survey method to know the condition of purse seine fishery in the field directly. Purse seine fishing vessels located in TPI Kranji in 2020 as many as 32 ships that have gross tonnage (GT) of 9 to 24 GT. The dominant catches are Longtail Tuna (Thunnus tonggol), Mackerel Tuna (Euthynnus affinis), Fringescale Sardinella (Sardinella fimbriata), Short Mackerel (Rastrelliger brachysoma) and Goldstripe Sardinella (Sardinella gibbosa). There are two seasons in the fishing process at TPI Kranji, the regular season (Fringescale Sardinella) and the peak season (Tuna). The highest value of productivity per trip was obtained 1.59 tons / trip / year which occurred in 2019 with 223 of fishing trips and the amount of catch production of 356.71 tons. The highest value of productivity per GT occurred in 2020, obtained 2.09 tons / GT / year, which currently has 32 purse seine vessels. The productivity per GT from year to year is increasing because the amount of production is also increasing every year.

Abstract

Prigi, Trenggalek is a potential fishery area located in the southern part of the East Java. Most fishers in Prigi uses trammel net as a capture device. The purpose of this research is to analyze the correlation of oceanographic parameters on the production of trammel net in Prigi’s fishing ground. The data used in this research are temperature, pH, salinity, velocity of currents, depth, and trammel net production during 35 trips. Oceanographic parameters in the fishing ground are temperature ranges from 26°C - 31°C, pH ranges from 7 – 9, salinity ranges from 25‰ - 35‰, current velocity range 0.13 m/s - 0.39 m/s, and the water depth ranges from 10 - 18 m. Variability from trammel net production are long tongue sole (Cynoglossus sp), crab (Portunus sp), endeavour shrimp (Metapenaeus sp), sea snail (Bufonaria sp), common ponyfish (Leiognathus sp), japanese threadfin bream (Nemipterus sp), squid (Loligo sp), and giant tiger prawn (Penaeus sp) with total production 302.2 kg. Correlation between oceanographic parameters and trammel net production are high for the current velocity with correlation value 0.78, and medium for depth and temperature with correlation value are 0.56 and 0.45, respectively. Correlation between salinity and pH with trammel net production are low and very low with correlation value -0.23 and 0.002, respectively.

Abstract

Pelabuhan Ratu is an area that has high wave energy potential and can be used as renewable energy. Wave energy harness the power of ocean waves into an electrical energy. The purpose of this research is to estimate the potential of wave energy in the month of Muharram and Rajab (Islamic/Hijriyah calendar) in the year 2018. It is based on local communities beliefs that the Muharram month has a high wave characteristic, and in this study compared with Rajab, the other month in Hijriyah calendar. The value of the forecasting waves in Muharram has a higher value compared to the Rajab. The estimated value of the power generated in the Muharram of 634.205 KWatt, whereas in the Rajab of 119.563 KWatt. The value is influenced to the fetch length. This wave energy potential then can be used to estimate the electrical power generated and the effect of the turbine on the application of the Oscillating Water Column (OWC) system.
