Abstract

Transport processes of broiler chicken pen to the slaughterhouse research can lead to stress. Transportation stress substantially unavoidable, but that does not mean that the negative effects of stress can not be reduced. Efforts to suppress the detrimental effects of stress alternative because of transportation one can do with management prior, through provision of rations containing turmeric (Curcuma longa) and drinking water containing palm sugar (Arenga pinata). The objective of this study is obtained implementation and delivery of palm sugar turmeric pre-tarnsportation to maintain the stability performance of broiler chickens. The study was conducted on 15 - 12 - 2011 in West Java Regency Sumedang District Village Buahdua Bentar Cibitung at farmer group chairman Mr Haji Mulyadi. Transportation routes from the village carried Bentar Cibitung - Cipadung - Nagrag or 2 hours, Village Bentar Cibitung - Cipadung - Nagrag - Cipadung - Tanjungkarta - Cipadung - Nagrag or 3 hours, Village Bentar Cibitung - Cipadung - Nagrag - Cipadung - Nagrag - Congeang - Nagrag or 4 hours. Each car transport speed 50-60 km/hour. Research carried out by using the method of factorial experimental design Completely Randomized Experiment 3 x 3 x 3. A factor is the transportation of animal with three replications, namely A1 is a 2 hour transportation, A2 is a 3 hour, and A3 is a4 hour transportation ; anti stress factor B with three replications, namely B1 is turmeric, palm sugar 2%, B2 is turmeric, palm sugar 3%, B3 turmeric, and palm sugar 4%. Statistical tests performed to test the influence of variance and differences between treatments were examined using by different test real honest.The study found that the implementation of turmeric, palm sugar in different rations and drinking water despite a weight loss ranging from 33.33 up to 70.33 g, increased body temperature ranges from 0.70 up to 1.30°C.

Abstract

are situated on the southeast border of the granite chalk belt of L. Jawa, and increasingly far from the recent subduction. From interpretation of seismic data of Pre-Tertiary rocks and Palaeogene and Neogene sediment, a tectonic direction was obtained, of the same direction as the Muria – Bawean back arc volcanic belt, namely Southwest – Northeast, or what is known as Pola Meratus. The development of the Palaeogene and Neogene tectonic in line with the aforementioned Plistosen-Holosen volcanic belt, points to the research area as an unstable tectonic and volcanically active from Palaeogene to Holosen. Other evidence of the Muria – Bawean back arc volcanic belt is the chemical composition of the five volcanic rock samples in area G. Muria shows genesis of Calc-Alkaline-Shoshonite magma. Total alkaline content is roughly between 3,08 - 13,92% including in the Andesit – Dasit group, and SiO2 is between 59 – 69,82% characterised medium-acidic. Results of microscopic analysis of the five rock samples show plagioclase mineral content, K-feldspar, hornblende, firoksen and glass dominant in all samples. Fomation of the aforementioned Palaeogene-Neogene (Pola Meratus) tectonic and Muria – Bawean back arc volcanic belt split the East JavaNorth basin in two, namely Pati Basin in the West and East Java North Basin in te East. The aforementioned tectonic and volcanic influence caused sub-basin orientation at Pati Basin and the East Java North Basin heading Southwest – Northeast. This condition has led to a new understanding of basin formatin and sub-basin orientation. Basic formation of a basin and sub-basin is not only based on the process of Palaeogene geology, but influenced by Neogene volcanism and tectonics. Similarities in the tectonic, volcanic and historical process of the formation of Pati Basin and the East Java North Basin show that the two basins have a petroleum system and the same prospectively high hydrocarbon content, so that if a more detailed exploration of Pati Basin is undertaken, it is predicted that hydrocarbon will be obtainable, as at the East Java North Basin, which is currently in production.

Abstract

Face recognition is one of biometrics and computer vision application, implemented widely in the fields of security, robotics and entertainment. The development of face recognition is still facing several problems such as illumination/lighting, pose and image size. Many methods have been proposed but there is still no satisfactory methodology. This research focused on a face re1cognition method based on Moment Invariant (MI) and Linear Discriminant Analysis (LDA). MI method is known as a method of producing the geometry characteristic of the object that are independent of translation, rotation, and scaling. The LDA method is a method of classification of objects by minimizing the within class object and maximizing the difference equation object. Based on these two methods, a novel method called MILDA has been successfully developed by combining moment invariant method and linear discriminant analysis. Experiments has been conducted using data from the AR-database. The database consist of 50 faces basic images which are extended into variation images by cropping, equalizing, resizing, andilluminating. The total images used in this research 450 images. Face image are grouped into two, consist of 150 training images and 300 testing images. The accuracy level of MILDA face image recognition is 92.00%. This method has been implemented on a robot using processed camera.
