Until now, orchids are still the center of attention of farmers and lovers of ornamental plants, because of their bright potential as cut flowers and potted plants. The popular and widespread type of orchid is Cattleya sp. The Cattleya orchid is also called the queen of orchids because of its colorful flowers. Cattleya sp. orchids take a long time to propagate by seed, about 4 to 7 years, so other methods are needed to deal with them. Tissue culture is a method for isolating plant parts such as cells, tissues or organs, and cultivating them in an aseptic environment. The purpose of this study was to determine the optimal interaction of growth regulators indole acetic acid (IAA), benzyl amino purine (BAP), and their interactions with the root induction of Cattleya sp. Cytokinins interact with auxin in determining the direction of cell differentiation. In this research method, differences in concentrations of indole acetic acid (IAA: 0, 2, 4, 6 ppm) and concentrations of benzyl amino purine (BAP: 0, 0, 5, 1 ppm) were carried out. Parameters observed were the number of roots and root length. Data were analyzed descriptively and inferentially using ANOVA. The highest number of roots was obtained in the treatment medium containing 0.5 ppm BAP and 6 ppm IAA, which was 6.33. The highest root length was found in the B0I4 treatment (BAP 0 + IAA 4 ppm). The results of the analysis of the interaction variance between the IAA treatment and the BAP treatment were 0.005, meaning that there was a significant effect of the combination of IAA and BAP on the leaf length of Cattleya sp.","PeriodicalId":422054,"journal":{"name":"JURNAL PEMBELAJARAN DAN BIOLOGI NUKLEUS","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117119033","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 sulkata tortoises were identified to determine their respective identities by measuring them morphometrically. Morphometric studies on sulkata tortoises are still minimal, so a morphometric study of the sulkata tortoises is needed. The purpose of this study was to identify and describe the morphometry of sulcata tortoises with three different age ranges kept in ex-situ conservation. The research sample used 15 sulcata turtles which were divided into 3 groups namely group A (1 year), Group B (2 years), and Group C (3 years). The morphometric parameters measured were body weight, head, carapace, plastron, forelimb, hindlimb and bridge. The results showed that the average body weight of group A, B and C turtles was 2,179 kg, 1,289 kg and 0,167 kg respectively. The average maximum carapace length in a row for groups A, B, C, namely 11.64, 23.18 and 16.72 cm. The average plastron lengths for groups A, B, C were 9.08, 6.44 and 9.24 cm respectively. The average forelimb length in groups A, B and C were 3.04, 6.28 and 7.78 cm respectively. The average hindlimb length for groups A, B, and C were 1.86, 3.5 and 4.04 cm, respectively. The average bridge width for groups A, B and C were 4.36, 8.94 and 10.1 cm respectively. Based on the results of morphometric measurements of the three groups of sulcata tortoises, it was shown that group C had a larger morphometric size than groups B and A, this was due to differences in age and growth factors.

An excess of metal can become toxic. The metal in question is copper (Cu). This research aimed to determine the phytoremediation effectiveness of Acorus calamus, Pistia stratiotes, and Azolla pinnata as candidates for Cu metal absorption. This investigation employed a wholly random factorial design with two factors: plant absorbent materials comprised of three plant species (Acorus calamus, Pistia stratiotes, and Azolla pinnata) and absorption concentrations of 2 and 5 ppm. The ANOVA test was used to analyze the data, followed by the average difference test. According to the results of this study, three plants—Acorus calamus, Pistia stratiotes, and Azolla pinnata—are capable of reducing Cu metal in water. The Acorus calamus plant can reduce Cu concentrations in water from 2 ppm to 96.85% and from 5 ppm to 96.80%. Pistia stratiotes plants can reduce Cu level in water from 2 ppm to 96.50% and 5 ppm to 99.94% at concentrations of 2 and 5 ppm, respectively.
