Applying Alpha-beta Algorithm In A Chess Engine

Minimax Algorithm, is a solution to reduce the burden on hardware in chess engine. However, a more in-depth method is needed to further increase the search algorithm. One of those solutions is called Alpha-Beta Pruning algorithm. The idea is to eliminate the unnecessary nodes in the search tree

Microanatomical Structure and Physical Characteristics of Thin Tail Hogget with Calpastatin (CAST-1) Genotype Differences

Thin tail sheep has good adaptation in tropics condition, but they have low meat quality. Quality of thin tail hogget can be improved by selection. Calpastatin (CAST) gene is an indigenous inhibitor of calpain that involved in regulation of protein turn over and growth. The objective of this research was to determine the effect of calpastatin-genotype on microanatomical structure and physical characteristics of thin tail hodget. Nine thin tail sheep from Jonggol were used for this research.PCR-RFLP method was carried out to identify genetic variation of calpastatin gene, based on the identificationof CAST variation genotype. It was found that MM and MN genotypes forcalpastatin gene with TT as asingle Calpain genotype variation. The sheep wasclustered based on the variation of calpastatin gene, 5 sheep hadMM genotype and 4 sheep hadMN genotype. Physical and microanatomical characteristics were analyzed from their meats. Sheep with MN genotype showed tougher meat, it was characterized with a greater of muscle fiber surface area, the number of muscle per muscle bundle and muscle bundle area and harder meat tenderness than in MM genotypes. Hypertrophy and hyperplasia of MN were greater than MM

Optimasi Proses Karbonisasi Tandan Kosong Sawit Menggunakan Response Surface Methodology

Empty fruit bunches (EFB) is a source of biomass which has not been utilized optimally yet. EFB can be used as source of solid fuel in the form of charcoal because of its high calorific value 18,200.75 kJ / kg. The calorific value can be increased by carbonization. Carbonization is a process to convert lignoselulose biomass into charcoal within temperature range 300 – 600 °C in a limited oxygen environment. The purpose of this research is to utilize EFB as a source of solid fuel, to study the effect of process condition such as temperature, holding time, and feed size towards the characteristics of resulted charcoal and to optimize carbonization process from the data obtained. Reactor used for EFB carbonization is a tube furnace at operating conditions of temperature (350, 400 and 450 °C), holding time (90, 120 and 150 minutes) and feed size (2, 4 and 6 cm). Responses were analyzed, namely the calorific value and volatile matter by using Response Surface Methodology (RSM). Optimum conditions obtained are temperature 450 °C, holding time 90 minutes and feed size 6 cm with calorific value 28,106 kJ/kg and volatile matter 13.47 %. The most influential process variable for calorific value is temperature. Meanwhile for volatile matter, every process variables give significant effect

Analysis of the Sustainability of Beef Cattle Breeding Business-Intensive Rearing Patterns in, Indramayu Regency, West Java

The increase population growth may cause an increase in the need for food originating from animal protein, one of which is meat. The demand for beef is not matched by an increase in the national cattle population or productivity. Policies on cattle breeding in the future require basic information, potential resources, and supporting facilities that are actualized in indicators and aspects of sustainability. The aim of the study was to analyze the index and status of the sustainability of a cattle breeding business with an intensive rearing pattern in Situ Bolang Indramayu, West Java, which was assessed from ecological, socio-cultural, economic, legal-institutional, and technological-infrastructure indicators. The method used is multidimensional scaling (MDS) with the Rap-UPTS approach for the analysis of index values and sustainability status. The identification of sensitive indicators, errors in index values, and sustainability in each aspect was carried out by Leverage and Monte Carlo analysis. The respondents amounted to 12 farmers. The results of the sustainability index analysis illustrate that the ecological indicators are 66.39, socio-cultural 57.14, economic 56.31, and legal-institutional 57.44, with a fairly sustainable status. In the Technology-Infrastructure Indicator 45.48, the status is less sustainable. It is necessary to increase the status of sustainability in the future, and it is necessary to make efforts to improve overall in all sensitive aspects of increasing the status of cattle breeding areas

Pembangunan Aplikasi Identifikasi Waktu Kawin Ternak Babi dengan Alihragam Wavelet dan Backpropagation

Abstract.Pigs are one of the animals that are usually bred for pork production. In order to have the pork production which meet the high level of consumption, it is necessary to handle the mating time for the nursery process so that pigs can mate at the right time to avoid problems such as pregnancy failure. Determination of the right mating time in pigs can be decided by observing the shape and color of female pig vulva that is opened and slimy. The uniqueness of vulva in this breeding season can be analyzed and identified by using Haar Wavelet and Backpropagation neural networks. Wavelets are used to perform image feature retrieval, while Backpropagation artificial neural networks are used to create a base of knowledge to decide whether the pigs are at the right mating time. This application is a web application built by Visual Studio 2015 MVC5 framework with C # programming language. Users can use this application by using the Android application. The construction of this application aims to enable pig breeder to get the right time of mating to increase the pork production. This application will also be made for the smart phone version in order to make the detection process with this application more efficient.Keywords: Pattern Recognition, Haar Wavelet, Backpropagation, Pig Breeding.Abstrak. Babi merupakan hewan yang diternakkan untuk dimanfaatkan dagingnya. Agar produksi daging babi dapat memenuhi tingkat konsumsi yang tinggi, diperlukan penanganan waktu kawin agar babi dapat kawin pada waktu yang tepat sehingga menghindari permasalahan seperti kegagalan kebuntingan.Penentuan waktu kawin yang tepat pada babi terlihat pada bentuk dan warna vulva babi betina yang terlihat terbuka dan berlendir. Keunikan vulva ini dapat dianalisis dan dikenali polanya menggunakan alihragam Haar Wavelet dan jaringan syaraf tiruan Backpropagation. Wavelet digunakan untuk pengambilan ciri citra, jaringan syaraf tiruan Backpropagation digunakan untuk membuat basis pengetahuan untuk mengkategorikan karakter yang membuat babi dinyatakan berada dalam waktu kawin yang tepat. Aplikasi ini merupakan aplikasi web yang dibangun dengan bahasa pemrograman C#. Dibangunnya aplikasi ini bertujuan agar peternak babi dapat mendapatkan waktu yang tepat untuk mengawinkan ternaknya agar produksi babi dapat meningkat. Aplikasi ini juga dibuat pada ponsel pintar agar proses pendeteksian dengan aplikasi ini menjadi lebih efisien.Kata Kunci: Pengenalan Pola, Haar Wavelet, Backpropagation, Ternak Babi
