EFFECT OF ANNEALING ON MAGNETIC AND STRUCTURAL PROPERTIES OF THE NANOCRYSTALLINE Fe-Mn-Al ALLOYS

In this work, the formations of Fe55Mn10Al35 nanocrystalline alloys were made by using mechanical alloying (MA) technique with the milling time of 24 hrs and then annealed at 300, 500, and 700oC. The sizes and the morphology of the particles were checked by using a Scanning Electron Microscope (SEM). The magnetic properties were characterized by using a Vibration Sample Magnetometer (VSM), and it give results both of the magnetic saturation (Ms) and Coercivity (Hc) are decreased respect to annealing temperatures. Last one; the structures were characterized by using an Extended X-ray Absorption Fine Structure (EXAFS) and X-Ray Diffraction (XRD). It give results that the structures were single phase at 24 hrs milled and 300oC annealed, then the structure to be changed at 500 and 700oC

A Review of the Travel Behavior Analysis: Its Basis and Application for Developing Cities

Travel, most often viewed in theory as derived from the demand for activity participation, has almost always been modeled on the trip-based basis, i.e., the trip is treated as the unit of analysis. Attributes of a trip (e.g., its origin and destination, mode, length) have been the subjects of analysis, but not the types of activities engaged in, their durations, sequences, and timing. This paper offers a brief review of the travel behavior analysis in order to provide a better understanding and forecasting of travel behavior. The article further offers discussions on its possible applications in urban areas of developing countries where historical accumulations of transportation and communications technologies are being introduced within a short span of time, creating the environment for travel which may not be properly accounted for using the conventional trip-based models of travel demand. In addition, the dataset from Malaysia was employed as a case of study

The utilization of alfalfa that planted at Tobasa highland, North Sumatra for growing Boerka goat feed

Alfalfa (Medicago sativa L.) is a herbaceus legume which is potential to be used as goat feed for it’s high production and nutritive value. This research was aimed to study the adaptation of alfalfa planted at highland-moderate climate and it’s utilization for goat feed. This research concists of two activities, ie 1) Agronomy of alfalfa that adapted to highland as a goat feed resource, and 2) The alfalfa usage technology as goat feed. On the first activity alfalfa was planted on highland-moderate climate Gurgur, Tobasa District, North Sumatra Province. Data was collected included: growth percentage, morphology and production aspects, and nutritive value. The harvesting was conducted for three times, where the first cutting had done at 100 days after planting. Investigation of morphology characterirtics was done before alfalfa harvesting. The utilization of alfalfa as goat feed was carried out on the second activity which was arranged in a completely randomized design. Twenty male Boer x Kacang crossbred  (Boerka) goats of 5-6 months of age with average body weight 14.2±0.8 kg were randomly assigned to four feed treatments where each treatment consited of five replications. The four feed treatments were: P1 = 100% grass + 0% alfalfa; P2 = 90% grass + 10% alfalfa, P3 = 80% grass + 20% alfalfa, and P4 = 70% grass + 30% alfalfa. Data observation included dry matter intake, average daily gain, feed efficiency, and income over feed cost. Results showed that alfalfa growth percentage was 65% with good growth and high either production or nutritive value. The average shoot dry matter production was 438.6 g/m2 which was equivalent to 26.3 t/ha/yr. The crude protein content of alfalfa on the first, second and third harvesting were 17.93; 21.89 and 17.73 per cent, respectively. The utilization of alfalfa that had been processed to be crude-meal can be applied as goat feed. Supplementation of 70% grass and 30% alfalfa meal showed the best results: ADG 59.17 g/d, feed efficiency 0.14, and IOFC Rp 736/h/d. Key Words: Alfalfa, Herbage, Production, Meal, Feed, Goa

Nutritional Support for Small Ruminant Development Based on Oil Palm By-products

Biomass by-products or plant residues from the plantation system would play a crucial role in animal production since the utilization of forages from the underneath tree crops would be less or minimal when the palm oil crop mature. By-products generated from the palm oil system vary, but in relation to the animal production they could be generally categorized into the fibrous by-products and the non-fibrous (concentrate) by-products. Palm oil mill effluent (POME) and palm kernel cake (PKC) are concentrate by-products produced during the processing of palm oil extraction which have great potency to support sheep and goat production, although limiting factors such as contamination of shell and high copper level in PKC need to be considered in their utilization as feed. The fibrous palm oil by-products include oil palm fronds (OPF) and oil palm trunk (OPT) generated from the palm crop trees and oil palm empty fruit bunch (OPEFB) and palm pressed fiber (PPF) generated from processing of fresh fruits to yield crude oil. These fibrous by-products cannot meet the metabolisable energy required for high growth rate and for lactation of sheep and goats due to low DM digestibility, low crude protein content, low fermentable carbohydrate and low level of intake. Limited inclusion level in ration should be applied for those by-products to yield an acceptable production level of sheep and goats. Pretreatments (physical, chemical, and biological) gave some improvement in their nutritional qualities, however additional cost of pretreatments need to be considered. In the future, there would be a great challenge for the utilization of those fibrous by-products as animal feed since bioconversion of lignocellulosic materials to products such as chemicals (bioethanol, sugar, and bioplastic), fuels, and organic fertilizers are receiving greater interest. Some comparative advantages of these natural wastes are their relatively low cost, renewable and widespread in nature for used in an industrial operation
