Liquid Smoke from Teak Leaves as Pestiside to Control Whiteflies
نویسندگان
چکیده
Jati merupakan salah satu tanaman yang banyak dijumpai di Indonesia. Daun jati memiliki komponen lignin, selulosa, dan hemiselulosa dapat diurai menjadi fenol asam dalam bentuk cairan, disebut asap cair, dengan proses pirolisis bermanfaat sebagai pestisida nabati. Tujuan dari penelitian ini adalah untuk membuat cair limbah daun kering metode pirolisis, mencari temperatur waktu relatif baik memperoleh kadar menguji keefektifan nabati hama kutu putih. Proses digunakan yaitu tahapan karbonisasi lalu dilanjutkan tahap kondensasi agar didapatkan cair. dilakukan variasi (°C) 200, 250, 300, 350, 400 serta (jam) 1, 1 ½, 2, 2 3. Diperoleh pada suhu 350°C 3 jam karena kandungan tertinggi masih sesuai SNI, sebesar 1,915% 14,885%. Asap uji menghilangkan putih konsentrasi 20% hasil bahwa efektif kurun sembilan hari

Adsorption of Cadmium(ii) Ions from Aqueous Solution by Tectona Grandis L.f. (teak Leaves Powder)
Batch adsorption studies were undertaken with the abundantly available waste biosorbent Tectona grandis L.f. leaf powder for removal of cadmium(II) from aqueous solutions. The adsorption experiments were performed under various conditions such as time, temperature, different initial Cd(II) concentrations, pH, adsorbent dosage, and adsorbent particle size. The data showed that in 30 minutes, 1 g...

متن کاملEndosymbiotic bacteria as a source of carotenoids in whiteflies.
Although carotenoids serve important biological functions, animals are generally unable to synthesize these pigments and instead obtain them from food. However, many animals, such as sap-feeding insects, may have limited access to carotenoids in their diet, and it was recently shown that aphids have acquired the ability to produce carotenoids by lateral transfer of fungal genes. Whiteflies also...
متن کامل2-methylanthraquinone as a marker of occupational exposure to teak wood dust in boatyards.
A new gas chromatographic/mass spectrometric (GC/MS) method was developed to detect 2-methylanthraquinone (2-MeA) in wood dust. 2-MeA is present in teak wood (a suspected human carcinogen) but not in oak, beech, mahogany, birch, ash or pine. The method involved collection of workplace dust on filters and extraction of 2-MeA with methanol and GC/MS analysis. The method was tested on teak wood du...
