Abstract

                                               AbstrakThis study was aimed to find out how the perception of parents whose children dropout in junior high school. In addition, this study also focuses on determining the relationship between parents' opinions about school dropout and the characteristics of respondents in the Perlis village Pangkalan Berandan subdistrict Langkat district North Sumatra province. With the respondents no less than 32 people are parents whose children drop out.The results of this study indicate that the perception of the parents were whole parents who did not go to school to experience that good education for children. Education is important for the future of the child. Children's behavior can also be influenced by education. Children who stop schooling at an equivalent lower level usually do not think of education because they are busy to earn an income. The research results showed that the parent-perception relationship with the fishermen's character had a significant relationship with income, the number of dependent and fishery education levels. It seems that the income, the number of dependents and the level of education have a relationship with the perceptions of parents. Keywords: Education, Perception, Fishermen

Abstract

 ABSTRACT The research of the profit sharing system of squid fishing using fishing gear stick held dip net landed at the Ocean Fishing Port Belawan North Sumatera Provinceheld on 5 March to 22 March 2018. This study was aimed to: 1) know the employment assignment based on the position, 2) describe the system for the catch between the fisherman owner and the fisherman, and 3) the income ratio between the fisherman owner and the worker fisherman using the system for the local result Law No.16 of 1964. The method used is survey method with the determination of respondents done by stratified random sampling.            The results of this study indicate that the division of tasks against the effort labor of fishing stick held dip net has been in accordance with their respective positions and profit sharing system applied in this fishing business is a system of local revenue sharing with the percentage of profit sharing 60% for the owner and 40% for fishermen laborers. Owner's income is 30 GT (IDR.60,030,000), fisherman's labor (IDR.40.020.000), and for the 40 GT fisherman owner (IDR.143.120.000), fisherman's labor (IDR.57.248.000). While using the profit-sharing system according to the Act, the income of fishermen laborers rose with the highest percentage increase of 107%. Such a far-reaching income comparison proves that the profit sharing using Law No.16 of 1964 is better than the local revenue share.Keywords:System, Profit Sharing, Revenue, Fishermen, Stick Held Dip Net

Abstract

Abstract Hemirhamphodon pogonognathus is a typeof freshwater fish that inhabit waters around the Riau University. This fish is potential for decorative fish. Information on biological, including morphometric, meristic, and growth patterns, however, is rare. To understand the morphometrical and meristicalcharacteristics and also the growth pattern of the fish, a research has been conducted February-March 2018. There were 100 fishes (33.35-82.65 TL mm and 1.3-0.1 gr BW). There were 28 morphological characteristic measured and 11 meristical characteristic counted. The meristicalcharacteristics obtained were as follows: D.15-17; P.5-8; V.5-6; A.8-9; C.17-20. The number of scale in the pre-dorsal fin was 47-52, around the body 52-62, in the caudal peduncle was 14-16, in the lateral line was 98-110, above lateral line was 19-25 and under lateral line was 25-31.Resylts  of Withney test shown that there were 9  morphometrical characteristic differences between male and female. They were height  of caudal-peducle depth, distance between dorsal fin and the base caudal fin, height of dorsal fin, length pectoral fin base, anal fin height, length of ventral fin base, height of ventral fin, length of caudal fin base, and height of caudal fin.The length-weight relationship shown that the growth of male and female was isometric. Keywords: freshwater fish, isometric, decorative fish, morphological characteristic, meristic characteristic

Abstract

                                            ABSTRACT                                                                 Diatom are microscopic plants as primary producers for most marine biota. This research has been held on March 2018 in Intertidal Zone of waters Kuala Tanjung Sei Suka Subdistrict, Batu Bara Regency, North Sumatera Province. The purpose of this study was to determine the genera epiphelic diatom abundance of Nitrate, Phosphate and Silicate concentrations and to know relationship of epiphelic diatom abundance with concentrations of Nitrate, Phosphate and Silicate. Sediment samples was taken from 4 stations and each stations was divided based on the intertidal zone (lower, middle and upper). Sample identification was obtained from 4 genera of diatom centrales and 9 genera of diatom pennales. Epiphelic diatom abundance was found in each zone ranged from 343 - 5319 ind/cm2 and at each station ranged from 686 - 6634 ind/cm2. Nitrate concentrations ranged from 0.0125 - 0.0958 mg/l, Phosphate concentrations ranged from 0.1150 - 0.8385 mg/l, and the concentration of Silicates ranged from 0.1529 - 0.3301 mg/l. Simple linear regression analysis indicates a very low negative correlation between Nitrate with abundance the epiphelic diatom, a negative correlation between Phosphate with epiphelic diatom abundance and negative correlation between Silicate with epiphelic diatom.Keyword: Intertidal Zone, Epiphelic Diatoms, Nitrate, Phosphate and Silicate

Abstract

AbstractHampalamacrolepidota is a carnivorous  fish that inhabit the Kampar Kiri River, Mentulik Village. In the Kampar Kiri River there is waste from illegal gold mining, domestic waste, and floating cage aquaculture activities that pollute the water. The pollution may negatively affects small aquatic organisms that represent as prey for H. macrolepidota.To understand the type of food consumed by H. macrolepidota, a study has been conducted from  February to April 2018. Sampling was conducted 4 times, once/ 2 weeks for a two months period. There were 52 fishes captured, 19 fishes had full stomach and the others had empty stomach. Fish stomach was dissected, and each type of stomach contents was identified and weighed.Results shown that the content of the fish stomach consists of fish, leaves, and insect remains. The main food of H. macrolepidota is fish (Preponderance Index 90%).Keyword:Cyprinidae, Feeding Habit, Index of Preponderance, Carnivore fish.
