Abstract

Use of synthetic fertilizers bring environmental pollution, increase weed growth, reduceatmospheric oxygen levels, decrease the fertility of agricultural land, causing eutrophicationand run-offs, also even damaging coral reefs. Recent biotechnology approaches can beutilized to create a new variety of self-fertilization plants that allows it to supply its ownnitrogen making it possible to overcome nitrogen problems and avoid them. This reviewaims to understand how far genetic engineering approach can be used by the introduction ofnif regulon from Klebsiella penumoniae. The nitrogenase-encoding genes which make up thenif regulon proved can be inserted into the mitochondrial genome as like Allen et al. (2017)did in their research. The western blotting result showed that the research succesfullyintegrated the nif regulon to the genome and expressed their proteins.

Abstract

Cassava bagasse is a by-product of tapioca industry whose use as food is relatively limited.The improvement of the cassava bagasse flour characteristics as a food ingredient can bedone through a semi-solid fermentation process. The aim of this study was to examine thechanges in physicochemical characteristics of cassava bagasse flour during the semi-solidfermentation process using Saccharomyces cerevisiae. The semi-solid fermentation processwas carried out for 0 days (control), 1 day, 2 days, 3 days, 4 days, and 5 days. Observationsof physicochemical characteristics include pasting characteristics, microstructure, waterabsorption index, and water solubility index. The results showed that the fermentationprocess had no effect on the gelatinization temperature but affected the viscosity of thecassava bagasse flour; during fermentation, liberation and erosion of the starch granule willbe more intense occur, as well as an increase in water absorption index and water solubilityindex.

Abstract

The research was conducted in February to June 2015 in the District of Rajabasa Raya, Bandar Lampung. Research used design of randomized perfect group design with five dosages of compound NPK fertilizer (16:16:16), i.e., 0, 25, 50, 75 and 100 kg/ha applied at R1 (early Flowering) and repeated three times. Homogeneity was tested with Bartlet and the addition data was tested with Tukey, and analysis of kind (if applicable). Mean separation test used orthogonal polynomial on the level of confident 5%. The results showed that application of compound fertilizer NPK 16:16:16 increases soybean yield (t/ha) and nutrient efficiency. However, NPK applications have no effect on plant height, plant dry weight, number of total branches, number of productive branches, total number of pods, and weight of 100 grains of soybean seeds. Dosing up to 100 kg/ha of NPK compound increase soybean yield but still shows a linear graph Keywords: soybean, early flowering (R1), NPK fertilizer, NPK dose.

The objective of this research was to know effect of citric acid, aluminum, and their itsinteraction on the seedling growth of hibrida maize (Zea mays L.) Var. Bisi-18. Theexperiment was conducted during January 2016 in Plant Physiology Laboratory,Department of Biology, Faculty of Mathematics and Natural Science, University ofLampung. The experiment was implemented in 2x3 factorial experiments. Factor A wasAluminum with 2 levels: 0 mM, 5 mM. Factor B was Citric Acid with 3 levels: 0 mM, 5 mM,and 10 mM. After selected corn seeds were soaked in citric acid solution for 24 hours, andgerminated in plastic tray. After 7 days seedlings were planted in plastic containers thatcontain aluminum solution. Variables in this research were shoot length, seedling freshweight, shoot root ratio, and relative water content after 7 days of growing period. Analysisof variance was conducted at 5% significant level. If interactions between aluminum andcitric acid was not significant, main effect was determined at 5% significant level with LSDtest. If interactions between aluminum and citric acid was significant, simple effect wasdetermined at 5% significant level with F test. The result showed that no aluminum effectobserved on all variables, and citric acid affected negativly all variables. No interctionsbetween aluminum and citric acid on all seedling growth variables of maize hibrida Var.Bisi-18. It is concluded aluminum 5mM was not able to cause stress in maize seedling. Inno stress condition citric acid has negative effect on maize seedling growth.Keyword: Citric acid, Aluminium, Maize Seedling, Shoot Length, Seedling Fresh Weight.
