Abstract

ABSTRACTForeign Plants Invasive (Invasive Species) have the ability to grow and develop very quickly in an ecosystem so that they can cause environmental damage. The purpose of this research is to find out the structure and composition of weed plants in the area of Mount Sibuatan, Nagalingga Village, Brand District, Karo Regency, North Sumatra, using the checkered line method with 10 x 10 m in size plot which is placed by purposive sampling. Based on the research that has been carried out, it was obtained 20 families of 34 species with 452 individuals that divided into three levels of vegetation, namely trees, sapling and basic vegetation. The dominant families found consisted of the Asterceae and Euphorbiaceae families with 64.12% and 76.43% of percentage, the co-dominant families were the Poaceae and Rosaceae families with 17.06 and 16.20% of percentage. The highest Importance Value Index (INP) of the area is the species of Austroeupatorium inulifolium (Kunth) R.M.King & H. Rob with a value of 92.37. The invasive plants diversity index has moderate abundance of plant diversity. The spread patterns of invasive plants are include into the category of groups.

Abstract

This investigation means to decide the impact on the development of goldfish seeds when taken care of pellets, to decide the impact on the development of goldfish seeds when taken care of with Lemna, and to decide the impact on the development of goldfish seeds when taken care of with a blend of pellets and Lemna. The exploration was directed from March - June 2020, at the Fish Seed Center, Bahorok District, Dusun VI, Timbang Jaya Village. Taking care of treatment A (100% pellets without giving lemna), Treatment B (75% pellets and 25% lemna), Treatment C (25% pellets and 75% lemna), Treatment D (half pellet feed and half lemna), Treatment E (100% lemna without pellets). The outcomes showed that the mix of pellet and lemna feed with a proportion of half pellets and half lemna significantly affected outright development, supreme weight, every day development rate, feed transformation rate, endurance rate, and water nature of goldfish (Cyprinus carpio).

Abstract

Tumbuhan bawah mempunyai peranan yang sangat penting dalam ekosistem, antara lain sebagai sumber obat-obatan, plasma nutfah, pengurangan erosi, siklus hara, peningkatan infiltrasi, dan tanaman hias. Tujuan dari penelitian ini adalah untuk mengetahui struktur dan komposisi tumbuhan bawah dan untuk mengetahui indeks keanekaragaman tumbuhan bawah di Gunung Sibuatan Desa Nagalingga Kecamatan Merek Kabupaten Karo Sumatera Utara. Metode yang digunakan yaitu metode survei dengan teknik pembuatan petak kuadrat secara purposive sampling pada tiga lokasi dengan ketinggian 1.600 mdpl, 1.800 mdpl, dan 2.000 mdpl dengan ukuran plot 5m x 5m. Struktur tumbuhan bawah dilihat dari nilai INP. Hasil penelitian ini diperoleh pada ketinggian 1.600 mdpl terdapat nilai INP tertinggi yaitu pada jenis Selaginella caudata (Desv.) dengan nilai INP sebesar 50,61. Pada ketinggian 1.800 mdpl terdapat nilai INP tertinggi yaitu pada jenis Argostemma uniflorum Blume ex DC dengan nilai INP sebesar 79,54. Sedangkan pada ketinggian 2.000 mdpl terdapat nilai INP tertinggi yaitu pada jenis Calamus viminalis Willd dengan nilai INP sebesar 37,75. Komposisi jenis tumbuhan bawah pada ketinggian 1.600 mdpl terdapat 16 jenis tumbuhan bawah dengan 13 famili. Pada ketinggian 1.800 mdpl diperoleh 11 jenis tumbuhan bawah dengan 9 famili. Pada ketinggian 2.000 mdpl diperoleh 11 jenis tumbuhan bawah dengan 8 famili. Indeks Keanekaragaman pada ketinggian 1.600 mdpl sebesar 1,75, ketinggian 1.800 mdpl sebesar 1,28, dan pada ketinggian 2.000 mdpl sebesar 1,91. Dari data indeks keanekaragaman tersebut yang menunjukkan keanekaragaman tergolong sedang, yaitu mempunyai komunitas stabil.

Abstract

Air gambut ialah air permukaan yang ada di dataran rendah tanah gambut, dengan intensitas warna berwarna merah kecoklatan. Penelitian ini bertujuan untuk mengetahui kelayakan pemanfaatan air gambut di Desa Sei Tawar Kec Panai Hilir Kab Labuhan Batu berdasarkan keberadaan bakteri Escherichia coli dan bakteri Staphylococcus aureus. Sampel di ambil dengan cara composite, jumlah sampel yang digunakan sebanyak 5 sampel. Uji yang dilakukan yaitu dengan isolasi dan identifikasi bakteri Escherichia coli dengan uji pendugaan, uji konfirmasi (peneguhan), isolasi- identifikasi dan uji IMViC yaitu uji produksi indole, uji Voges-Pro skauer (VP), uji Methyl Red (MR), uji citrate, sedangkan untuk Staphylococcus aureus dilakukan penanaman sampel pada media, uji identifikasi yaitu pewarnaan gram, uji koagulase dan dianalisis secara deskriptif. Hasil penelitian air gambut menunjukan pada kelima sampel air gambut uji bakteri Escherichia coli didapatkan nilai indeks MPN kode sampel S1 240 CFU sedangkan S2,S3,S4 dan S5 adalah 1.100 CFU dan di nyatakan positif mengandung bakteri Escherichia coli dan pada uji bakteri Staphylococcus aureus dengan uji koagulase positif dan dikalikan dengan faktor pengencerannya didapatkan hasil S1 175 x 10-1 CFU, S2 216 x 10-1 CFU, S3 316 x10-1 CFU, S4 x 10-1 CFU dan S5 352 x 10-1 CFU. Maka dari hasil analisi penelitian Air yang di gunakan tidak memenuhi standar baku mutu kesehatan untuk media air yang telah ditetapkan dalam MENKES No 32 tahun 2017 untuk bakteri Escherichia coli 0 CFU/ 100 mL air dan bakteri Staphylococcus aureus 100 CFU/ 100 mL air.

Abstract

This study aims to determine the ability of white radish tuber extract (Raphanus sativus L) in inhibiting the growth of bacteria Staphylococcus epidermidis and Propionibacterium acnes and to determine the effective concentration of white radish tuber extract (Raphanus sativus L) in inhibiting the growth of Propionibacterium acnes and Staphylococcus epidermidis. Based on the results of tests using Analysis of Variance SPSS 21 (ANOVA) showed that there was an effect of antibacterial effectiveness on Staphylococcus epidermidis and Propionibacterium acnes with a significance value (α <0.05). The 100% extract concentration in bacteria Propionibacterium acnes is the best concentration in forming the inhibition zone with a diameter of 15.6 mm and the 100% extract concentration in the bacteria Staphylococcus epidermidis is the best concentration in forming the inhibition zone with a diameter of 13.3 mm.

Abstract

This study aims to analyze the category of scientific literacy in class X biology textbooks at MAS Nurul Iman Mahato. The research used in this research uses a qualitative approach with content analysis. Content analysis is commonly used in analyzing the validity of the contents of a book to draw conclusions from the contents of books and documents using certain procedures. This research was conducted at MAS Nurul Iman located in Mahato Bandar Selamat Village, North Tambusai District, Rokan Hulu Regency, Riau Province with biology textbooks for class X in MAS Nurul Iman Mahato. Data collection used using interview and observation techniques. Analyzing the data obtained, the steps taken to obtain analysis data from the data that have been obtained by 1) Summing the occurrence of scientific indicators from each component of the scientific literacy category, 2) Calculating the percentage of occurrence of scientific literacy indicators in the books being analyzed 3) Calculating the reliability of the data 4) Draw Conclusions. From the results of the research discussed earlier, it can be concluded that there are several percentages of the appearance of the scientific literacy category in class X biology textbooks at MAS Nurul Iman Mahato. Viewed from the aspect of science as the body of knowledge, the presentation of scientific literacy in class X biology textbooks in MAS Nurul Iman Mahato of 46.68%, seen from the aspect of science as a way of knowledge that the presentation of scientific literacy in class X biology textbooks at MAS Nurul Iman Mahato is 19.55%, viewed from the aspect of science as a way of thinking that the presentation of scientific literacy in class X biology textbooks at MAS Nurul Iman Mahato by 13.30%, seen from the aspect of science as an aspect of science interaction with technology and social that the presentation of scientific literacy in class X biology textbooks at MAS Nurul Iman Mahato is 13.99 %.
