New Grand Rapids) is a vegetable plant that has a contains high nutrients. Efforts that can increase the production of lettuce is using hydroponics technology and the addition of growth regulators is gibberellin (GA3). This research aims to determine the effect of addition of GA3 to gowth of lettuce using floating technology system of hydroponics without circulation. The research was conducted for four months from May to August 2017 in the Green House and Laboratory of Biology of the Faculty of Mathematics and Natural Sciences, Tanjungpura University Pontianak. This research used a completely randomized design with five treatments (K) and three repetitions. The treatments given is the addition of GA3 with different consentrations: K0 (Control), K1 (5 ppm), K2 (10 ppm), K3 (15 ppm), and K4 (20 ppm). The result showed that the addition of GA3 didn’t significant affect on the number of leaves, but showed a significantly affected the height, root lenght, leaf areas, and fresh weight.","PeriodicalId":175944,"journal":{"name":"Jurnal Protobiont","volume":"509 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115889728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The seluang fish population (R. argyrotaenia) river downstream is in danger of declining as a result of public activity. The goal of the study is to identify the structure of R. argyrotaenia population  and the chemical factors of the water downstream from the Sekadau River. Data extraction takes place between March and April 2018. Fish are found three times in three weeks at a week's interval of 1 week at a time. Studies show that seluang fish (R. argyrotaenia) were found up to 213 individuals of 69 individuals females, 58 individual males and 86 individual unidentified. The seluang fish that is most commonly found 2-6 cm by 131 individuals, and the smallest one at 12-16 cm size  is 4 individuals.
