Banana is one of the most important global agriculture commodities. Asia accounts for the production of bananas amounted to 56.4% of total banana in the world and Indonesia is one of the banana-producing countries in Asia. The demand for bananas increased need is anticipated with good cultivation techniques to meet domestic and international market demand. Plant regeneration in vitro tissue culture techniques or can be used to produce propagules true-to-type in large quantities in a relatively short period and free from disease. This research aims to study the influence of various concentrations of BA (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, and 4.0 mg/l) against the growth and reproduction of Cavendish banana propagules in vitro. Time appears buds, propagules length and the number of propagules per explant, and the number of primary roots of plants per explant observed after eight weeks of culture. The experiment results show that after explant grown for eight weeks on the media's treatment shows the different response. The increased concentration of BA can increase the number of shoots. The increased concentration of BA from 0.5 mg/l be 1-3 mg/l increased the number of propagules, but the number of propagules will decrease in the concentration of BA more 3.5 or 4 mg/l. In addition to BA concentration 0.5, 1 and 1.5 mg/l MS media into producing shoot buds appear faster time high, highest propagules and root amount more on banana propagules Cavendish, but the number of shoots is fewer. The best of BA concentrations to induce propagules plant bananas Cavendish is 3.0 mg/l.

Pada penelitian ini dilakukan evaluasi terhadap pengaruh ukuran partikel kopi bubuk pada proses diskriminasi kopi bubuk dekafeinasi dan non-dekafeinasi menggunakan metode UV-VIS spectroscopy dan PLS-DA. Pengambilan spektra sampel larutan kopi yang sudah disaring dan diencerkan dilakukan dengan menggunakan UV-VIS spectrometer (Genesysâ¢ 10S UV-Vis, Thermo Scientific, USA). Untuk mengetahui dan mengevaluasi pengaruh ukuran partikel sampel kopi bubuk terhadap proses diskriminasi kopi dekafeinasi maka model PLS-DA dibuat untuk dua tipe model yaitu model PLS-DA lokal dan model PLS-DA global. Hasil menunjukkan bahwa model PLS-DA global mampu memprediksi jenis kopi dengan nilai RMSEP yang rendah untuk semua ukuran mesh (RMSEP= 0 0.077 untuk mesh 40, RMSEP= 0.049 untuk mesh 50 dan RMSEP= 0.115 untuk mesh 70). Untuk model PLS-DA lokal hanya mampu memprediksi dengan baik jenis kopi pada ukuran mesh yang sama dengan mesh sampel kalibrasi. Hal ini menunjukkan adanya pengaruh ukuran mesh terhadap hasil PLS-DA yang sangat signifikan.Â Â

Biological change by using BIMO-CF containing lactic acid bacteria is a practical technology that is easy to apply in the production of cassava flour. This research was conducted from May until August 2017 at Agrosains Park Natar with the aim to know the chemical characteristics of cassava flour from Klenteng and Casessart varieties. Observation parameters included analysis of moisture content, ash content, fat content, protein content, fiber content, total carbohydrate content, starch content, HCN content, and white degree at THP Polytechnic State Laboratory of Lampung. The results showed that the highest yield was produced by cassava flour from casessart variety with the addition of BIMO-CF were 23.11%. The water content of cassava flour produced ranged between 8.02-9.19%, by the quality requirements of SNI. The lowest ash content was cassava flour from casessart variety (1.19%) without the addition of starter. The addition of starter increased the protein content of cassava flour both of Klenteng variety (0.47%) and Casessart variety (1.11%), decreasing the fiber content for Klenteng variety (0.67%) and Casessart variety (0.90%). The amount of fat contained in cassava flour produced ranged from 0.69 to 0.87%. Carbohydrate content (Klenteng variety was 88.49%, and Casessart variety was 87,69%) and starch content (Klenteng variety was 85,98%, and Casessart variety was 84,83%), cassava flour with the addition of starter higher than cassava flour without the addition of starter. All of the cassava flour produced has HCN levels below the maximum limit (0.0216-0.0293%), while the degree of white (> 80%) has not met the quality requirements of SNI.
