Abstract

Sansivieria trifasciata has a cell wall consisting of high cellulose components which are reinforced by lignin, pectin and hemicellulose. Separation of fibers from bonds that strengthen fibers is still a major problem because the cell walls that are owned are very strong and stiff. In the activity of separating selolusa fiber there needs to be a process called retting. Residues from the retting process with chemicals can pollute the environment, separation by mechanical means produces fibers that are still rigid, and with soaking requires a lot of water and causes odor. The purpose of this study is how long the Pseudomonas earuginosa used can show cell proliferation; get a graph of growth patterns in Sansevieria trifasciata leaf preparations by adding nutrients and fiber quality from dew retting. This study uses an experimental method; there are 2 treatments, namely the addition of nutrition and without nutrition with 6 replications time 5 days, 10, days, 15 days, 20 days and 30 days. The results of this study were the number of treated cells with the addition of nutrients and without the addition of nutrients experiencing the lag phase of the 5th to 10th day and the exponential phase starting from the 10th day to the 30th day. Pseudomonas aeruginosa can soften the cell wall with dew-retting ability obtained by 3.0 nutritional treatment scores and a score of 1.5 treatments without nutrition. In the regression analysis ≥ , where there is a significant influence between the number of cells per unit and the addition of nutrients and without the addition of nutrients.

Abstract

The aim of this research is to identify the isofl avon compounds in the in-vitro cultured callus of soybean (Glycine max Merr.). This is an explorative research, in which callus were cultured in the B5 medium supplemented with 2 ppm 2,4 D. The friable callus were found when it was cultured in the solid medium containing 8 g/l agar and 20 g/l sucrose. When the callus and soybean were extracted with ethanol, a yellow colored substance appeared. If further analysis was done with thin layer chromatography (TLC) method employing 0,2 mm thin layer silica gel 60 F254 (DC-Plastikfolien Schicht-dicke), and eluent consisting n-Butanol - HCL 0.1 N (1:1), six light bluecolor nodes appeared under 366 nm UV light. The nodes have the following Rf: 0,14; 0,30; 0,52; 0,63; 0,79 and 0,92 respectively. This TLC result is comparable with the TLC result from soybeans since they have two nodes with the same Rf and color, namely blue color at Rf 0,81 and 0,92 respectively. Further confi rmation using HPLC (High Performance Liquid Chromatography) equipped with UVvis detector and Lichrospher 100RP–18, (10 μm) colom, as well as Hitachi D–2500 Chromato-integrator indicated that those similar two nodes identifi ed in the TLC were either daidzein or genistein. They can be detected by HPLC at 250 nm and 260 nm, when theywere eluated at the 80% metanol. The HPLC quantitative calculation indicated that concentration of daidzein is four time higher as it was compared with the daidzein concentration in the bean. The concentration of daidzein in the callus remained high up to 4–5 weeks after plantation. It’s concentration will decrease when the callus reached 6 weeks after plantation. Genistein as another component of isoflavon is not appear upon callus, while on soybean seeds extracts, both daidzen and genistein are detected.

Abstract

Ultrafine particles have been attached the attention for researchers due to their impacts on human health. Ultrafine particles can be emitted fromburning process, such as forest burning, agriculture waste burning, cigarette, etc. In this study, ultrafine particles produced by cigarette smokes hasbeen investigated as a function of smoking rate. The samples consisted of different types of Indonesia cigarette called Kretek cigarette. Thequantification of emission factors was conducted by the burning of the cigarette samples, then the smoke that was sucked with a different flow rateusing an adjustable pump. The flow rate was chosen to correspond as close as the variation of the rate that people smoke. The measurements ofultrafine concentrations were carried out using an ultrafine particle counter P-Trak TSI 8525 capable of measuring particles with the diameter in therange of 20 to 1000 nm. The results showed that the emission factor of ultrafine particles significantly depended on the smoking rate. A highersmoking rate produced higher average ultrafine particle emission factor.

Abstract

Peningkatan mutu pada tanaman anggrek juga dapat ditingkatkan pada teknik persilangan dan perbanyakan biji hasil persilangan. Kegiatan persilangan banyak menggunakan varietas-varietas dengan tetua yang sama sehingga menyebabkan variasi genetik pada hibrida yang terbentuk menjadi terbatas. Tujuan penelitian ini adalah untuk mendeskripsikan karakteristik bunga tetua anggrek Dendrobium yang digunakan sebagai indukan dan menganalisis bunga pada generasi hasil persilangan. Penelitian ini menggunakan metode kualitatif dengan cara mendeskripsikan karakteristik bunga tetua anggrek dengan variasi berbeda serta bunga pada anggrek hibrida hasil persilangan. Analisis dilakukan melalui pendekatan morfologi secara langsung. Hasil yang diperoleh adalah anggrek hibrida hasil persilangan yang telah berbunga memiliki morfologi bunga yang mirip seperti kedua tetua persilangannya seperti ukuran bunga, warna bunga, bentuk dan warna sepal maupun petal, dan warna dari labellum tergantung dari karakteristik bunga yang terdapat pada kedua tetua persilangannya. Kesimpulan yang didapat berupa pemilihan tetua persilangan ditentukan sesuai karakter bunga yang dikehendaki sehingga menghasilkan generasi yang memiliki variasi bunga baru dan bunga dari anggrek hibrida yang dihasilkan dari pemuliaan anggrek memiliki campuran karakteristik bunga dari kedua tetua anggrek yang digunakan sebagai indukan persilangan, tetapi tidak semua karakter bunga dari kedua tetua muncul, ada beberapa karakter bunga yang muncul dari salah satu tetua. Improving the quality of orchid plants can also be improved on the technique of crossing and seed propagation from crosses. Crossing activities use a lot of varieties with the same parents, causing genetic variation in the hybrids formed to be limited. The purpose of this study was to describe the characteristics of the flower of the Dendrobium orchid parent used as a parent and to analyze the flower in the generation of crosses. This study uses a qualitative method by describing the characteristics of the flower of elder orchids with different variations and the flowers on hybrid orchids from crosses. The analysis was carried out through a direct morphological approach. The results obtained are hybrid orchids that have flowered from crosses that have flower morphology that is similar to the two parents of the cross, such as flower size, flower color, shape and color of the sepals and petals, and the color of the labellum depending on the characteristics of the flowers found in the two parents of the cross. The conclusion obtained in the form of the selection of the crossing parent is determined according to the desired flower character to produce a generation that has new flower variations and flowers from hybrid orchids produced from orchid breeding have a mixture of floral characteristics from the two orchid elders used as cross breeders, but not all flower characters. from the two elders who appeared, several flower characters emerged from one of the elders.

Abstract

Causes of degenerative diseases are caused by activities and unhealthy lifestyle. unhealthy lifestyle which in turn triggers free radicals. free radicals are moleculs that are not oxidized which cause the formation of new molecules that can damage body cells. free radicals can be overcome by giving natural antioxidants, one of which is form the olive plant (Olea europaea L.).The purpose of this study was to determine the effect of temperature treatment on antioxidant activity in olive leaves based on leaf age by calculating the IC50 value. The method used in this research is the DPPH method. Based on the results of the study, it can be concluded that the temperature of 31.6°c in young leaves according to calculations is categorized as a strong antioxidant because it provides a calculated value of 82.778 ppm and 165.093 ppm on old leaves and classified as moderate antioxidants, while temperature of 44°c give dominant level under 31.6°c with IC50 values 123.78 ppm for young leaves and 165.170 ppm for old leaves and classified as moderate antioxidants according to the theory that compounds that have very strong antioxidant activity values IC50 values are less than 50 ppm, strong if the IC50 are between 50 and 100, moderate antioxidant if the IC50 values are feasible 100-250 ppm, weak if the IC50 value is 250-500 ppm and inactive if the IC50 value is more than 500 ppm. and vice versa related to the selection of leaf age also affects the level of antioxidant activity seen from the comparison of results from the two treatments that young leaves have a higher level of antioxidant activity than old leaves in counteracting free radicals.Keywords : Temperature, Antioxidant, Olive (Olea europaea L.), DPPH.ABSTRAKPenyebab penyakit degeneratif disebabkan karena aktivitas dan pola hidup yang kurang sehat. Pola hidup kurang sehat yang pada akhirnya memicu radikal bebas. Radikal bebas adalah molekul yang tidak teroksidasi yang menyebabkan terbentuk molekul baru yang dapat merusak sel tubuh. Radikal bebas dapat diatasi dengan pemberian antioksidan salah satunya dari tumbuhan zaitun (Olea europaea L.). Tujuan dari penelitian ini adalah untuk mengetahui pengaruh perlakuan suhu terhadap aktivitas antioksidan pada daun zaitun berdasarkan umur daun melalui perhitungan nilai IC50. Metode yang digunakan dalam penelitian ini adalah metode DPPH. Berdasarkan hasil penelitian dapat disimpulkan bahwa perlakuan suhu 31.6°C pada daun muda  menurut perhitungan IC50 dikategorikan sebagai antioksidan kuat karena memberikan nilai hasil perhitungan IC50  sebesar 82.778 ppm dan 165.093 ppm pada daun tua dan tergolong antioksidan sedang, sementara pada perlakuan suhu 44°C memberikan pengaruh lebih rendah dibandingkan dengan perlakuan suhu 31.6°C dengan nilai IC50 sebesar 123.78 ppm untuk daun muda dan 165.170 ppm untuk daun tua dan tergolong antioksidan sedang sesuai teori bahwa senyawa yang memiliki nilai aktivitas antioksidan sangat kuat jika nilai IC50 kurang dari 50 ppm, kuat apabila nilai IC50 bernilai antara 50 sampai 100, antioksidan sedang apabila jika nilai IC50 bernilai 100-250 ppm, lemah jika nilai IC50 bernilai 250-500 ppm dan tidak aktif jika nilai IC50 bernilai lebih dari 500 ppm, begitupun sebaliknya terkait pemilihan umur daun juga berpengaruh terhadap tinggi rendahnya aktivitas antioksidan dilihat dari perbandingan hasil dari kedua perlakuan bahwa daun muda memiliki tingkat aktivitas antioksidan lebih tinggi dibandingkan dengan daun tua dalam menangkal radikal bebas.Kata Kunci : Suhu, Antioksidan, Zaitun (Olea europaea L.), DPPH.
