Abstract

Lemon Citrus (Citrus limon (L.) Burm f.) is one of the plants that has potential as a traditional medicine, and is an excellent source of vitamin C and calcium. Lemon leaf lemon can help overcome cancer, heart and liver. The purpose of this research is to characterize simplicia leaf and to know the chemical compound group contained in leaf. Characterization of simplicia include macroscopic and microscopic examination, determinations of loss on drying, determinations of water soluble extract, determination of ethanol soluble concentration, determination of total ash content, and determination of acid ash in soluble. Phytochemical screening includes the test for alkaloids, flavonoids, steroids/triterpenoids, tannins and saponins. The result obtained from examination of lemon citrus leaf characteristic gave loss on drying 69,29%; total ash content 6,40%; acid insoluble ash 1,23%; ethanol soluble extract 17,73%; water soluble extract 24,79%. The result of phytochemical screening showed that lemon leaf simplicia extract contains alkaloids, flavonoids, steroids/triterpenoids and tannins.

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.

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.

Abstract

The first step of tifoid fever diagnosis is through the test of leukocyte levels using hemadializer. Leukocytes are a major component of body immunity, especially in the fight against infection. Early symptoms of typhoid fever resemble fever in general, so it needs to be continued with more specific test one tubex test as applied to clinical pathology laboratory Islamic Hospital Sakinah Mojokerto. The results obtained are leukocyte levels in patients divided into three categories, below normal limits, normal, and above normal levels. So the case of typhoid fever becomes very interesting to continue to be studied and presented mechanism of the infection in detail.
