Abstract

ABSTRACTThe Ericaceae family has benefit as medicines and ornamental plants, because several types of the Ericaceae family have very attractive colors, fruits and flower shapes, besides that they have important ecological and economic values. This study aims to determine the types and morphology of the Ericaceae family in the Sicikeh-cikeh Lake Nature Tourism Park Lae Hole Village Parbuluan District Dairi Regency Sumatera Utara. This research were conducted in October - January 2020 using the exploration methods, namely by exploring along the path of the research location. The results of studies that have been carried out found 7 types of family Ericaceae, such as 4 of the genus Rhododendron, 1 of the genus Vaccinium, 1 of the genus Diplycosia, and 1 of the genus Cavendishia. The types of the Ericaceae family were found in this study had the same morphology, which has a taproot. The shape of the stem was round, and the direction grows perpendicular (erectus). The leaves are single leaves. Flowers including majmuk flowers, (terminal), and has flower parts, namely the crown of flowers, stamens and pistil. The fruit had a capsule and buni fruit. Keywords : Inventory, Ericaceae Family, Morphology, Sicikeh-cikeh Lake Nature Tourism Park

Abstract

Echinoidea (Phylum Echinodermata) is an aquatic biota that has economic value both economic and ecologic. Echinoidea has the characteristics of thorns which can be used as one of the characters in identification and classification. One of classify Echinoidea is to use the numerical-phenetic method. This method was groups each species according to the morphological similarities observed and account. This study aims to determine the types of Echinoidea and its important to grouping because it has important economic value in the fisheries sector and in conducting the data collection of Echinoidea biodiversity. This study used 7 species of Echinoidea namely Tripneustes sp., Euchinotrix sp., Euchinometra sp., Diadema sp., Stomopneustes sp., Heterocentrotus sp., and Colobocentrotus sp. This study used descriptive qualitative method. Analysis data used MVSV 3.1 application for similarity matrix (Simple Matching Coefficient and Jacard Coefficient) and dendogram. The results showed thorns as a characteristic in the classification of Echinoidea. Echinoidea classification shows two groups that have the highest value, namely Euchinotrix sp., And Diadema sp with 80% similarity value and Colobocentrotus sp with Echinometra, sp which is 76% (Simple Matching Coefficient). Whereas based on Jacard Coefficient the two groups have the same similarity value of 53%. Keywords: numeric-fenetic, echinoidea, similarity

Abstract

Science is an important part of man because it plays a major role in changing the mindset of man. Education is a human medium for gaining knowledge. The world of education, especially biology is a science that studies the knowledge of living things in the universe consists of humans, plants and animals, they have a cell with a unique name and very difficult to remember. Dictionaries are books containing terms, meanings and words used as a tool to translate the language. The dictionary is usually physically always thick so that when taken will be heavy and takes place. Bioinformatics is defined as the application of computational tools and analysis to capture and interpret biological data. The design of a cell term dictionary application so that it is easily searched for its cell term is part of the result of bioinformatics, and to generate a computerized search term that is difficult to use Boyer Moore algorithm. The Boyer Moore algorithm is the best string matching algorithm due to its ability to quickly match the searched strings. Application of Bayor Moore algorithm in dictionary application required design of process model using DFD and design database can be easily implemented to application system

Abstract

Kertas pada umum merupakan bahan yang tipis dan rata yang biasanya terbuat dari kayu dengan kadar serat selulosa 39%. Maka dapat diprediksikan bahwa akan terjadi eksploitasi hutan secara besar-besaran yang dapat mengakibatkan terganggunya kestabilan lingkungan sehingga perlu mendapat perhatian khusus dan mencari alternatif dengan bahan lain. Bahan alternatif yang dapat digunakan antara lain jerami, ampas tebu, merang ,pelepah pohon pisang, batang keladi, batang genjer. Pada pembuatan kertas, penambahan larutan NaOH atau CaO, berfungsi untuk melarutkan lignin saat proses pembuburan (pulping) sehingga mempercepat proses pemisahan dan pemutusan serat. Penelitian ini bertujuan 1). Untuk mengetahui ketahanan tarik dan ketahanan sobek kertas dari batang genjer melalui Chemical Pulping (proses Kimia) dengan menggunakan NaOH dan CaO yang berbeda.2). Untuk mengetahui uji sensoris kertas dari Batang Genjer dan batang keladi melalui Chemical Pulping (proses Kimia) dengan menggunakan NaOH dan CaO.Penelitian dilakukan di Lab. Biologi Prodi Biologi UINSU Penelitian ini menggunakan metode eksperimen dengan rancangan acak lengkap (RAL) pola faktorial dengan 2 faktor.

Abstract

Cilembu Sweet Potato is one type of sweet potato that is typical in the West Java area precisely in the Cilembu village or Sumedang. Cilembu sweet potato has a typical characteristic that is taste like honey if it fermentation and then roasted. Rizospheric bacteria with the ability of phosphate solvents are one of the factors supporting growth in plants. The research aims to identify Rhizosphere bacteria in Cilembu sweet potato roots which have the ability as phosphate solvents at two locations during the growth phase. The study was conducted with qualitative by testing the biochemical characteristics and ability of phosphate solvents. The result of this research show that Rhizosphere bacteria with the ability of phosphate solvents at the location of Cilembu (LCI) and Jatinangor (LJA) are not significantly different. In LCI, 12 isolates were obtained and in LJA 7 isolates were obtained. So that it can be concluded that the diversity of rhizosphere bacteria can be influenced by the characteristics of the soil and the growth phase.Keywords: Cilembu yam, Rizosphere bacteria, phosphate solvent

Abstract

Peningkatan sektor transportasi di sekitar daerah perkotaan kota Medan semakin berkembang pesat. Hal tersebut sejalan dengan peningkatan polusi udara. Mempertimbangkan dampaknya pada ekonomi, kesehatan, dan lingkungan, polusi udara merupakan masalah lingkungan yang sangat mendesak untuk ditangani. Emisi yang dikeluarkan oleh masing – masing kendaraan menimbulkan akumulasi pencemar di udara. Lumut kerak dapat menunjukkan adanya perubahan keadaan, ketahanan tubuh, dan memberikan reaksi sebagai dampak perubahan kondisi lingkungan yang akan memberikan informasi tentang perubahan dan tingkat pencemaran lingkungan. Terkait dengan fungsinya sebagai bioindikator, maka keberadaan lumut kerak dapat digunakan sebagai bagian dari observasi penelitian dengan mengambil kawasan yang berbeda kondisi. Berdasarkan hasil penelitian diketahui bahwa adanya perbedaan antara kawasan yang sedikit polusi (A3) dengan daerah yang banyak polusi udara (A1 dan A2). Pada lokasi pengamatan yang berada dekat dengan sumber pencemar ditemukan beberapa lumut kerak memiliki kecenderungan warna dari thallus adalah hijau kusam. Sedangkan kawasan A3 memiliki jumlah lumut kerak yang lebih banyak. Rata-rata diameter lumut kerak A1 adalah 2.25 cm; pada A2 adalah 3.3 cm, dan pada A3 adalah 1.75 cm. Perbedaan diameter tersebut tidak berbeda signifikan diantara ketiga kawasan tersebut.

Abstract

Ruthab dates are believed to have benefits for couples who want to have a descendant because it has phytoestrogen content that has an important role in the female uterine blood vessels that can increase fertility. Phytoestrogens have estrogenic activity that has similar structures with natural estrogens. The purpose of this study was to investigate the effect of fitoestrogen of  date palm fruit (Phoenix dactylifera L.) to synchronize the estrous cycle in mice (Mus Musculus L.). Animals try to use 24 Balb / C starbine female mice. The test material in the form of extract of dates is given orally at doses of 260 mg/kg BB, 780 mg/kg BB and 1820 mg/kg BB. Data were analyzed by simple linier regression test with 5% significance level. The results showed a significant influence between the control and treatment group (R = 0.767) so that it can be concluded that the effect is caused by the action phytoestrogens  hormones in the content of dates.
