Abstract

Banyak cara serta pendekatan yang dapat dilakukan oleh perusahaan manufaktur dalam mengukur tingkat produktivitas, salah satunya yang diterapkan oleh PT Yanmar Diesel Indonesia yang memproduksi mesin diesel yang diaplikasikan untuk produk pertanian, kelautan dan industri alat berat. Untuk mengukur produktivitas dan efisiensi dari mesin diesel buatan Yanmar tersebut diperlukan dua macam pengukuran yaitu input (pembelian) dalam hal ini pembelian komponen, dan output (penjualan) dalam hal ini berupa penjualan mesin diesel Yanmar. Semua pengukuran tersebut dilakukan dalam jangka waktu periode tertentu yang meliputi juga biaya tenaga kerja, perawatan dan energi. Penjualan dan pembelian merupakan salah satu faktor yang dominan untuk mengetahui tingkat produktivitas dan efisiensi dari suatau produk selain faktor-faktor pendukung yang lainnya yaitu, tenaga kerja dan modal. Setelah dilakukan perhitungan dengan menggunakan total produktivitas pada short term produktivitas, diperoleh rata – rata tingkat produktivitas yaitu sekitar 5. Kata kunci: Produktivitas, Pengukuran, Penjualan, Pembelian

Abstract

This research introduces branching processes as a stochastic process for estimating the number of the population of individuals at any generation “n”. One of the most interesting applications of branching processes is calculating the probability of eventual extinction. In probability theory, a branching process is a Markov chain that models a population in which each individual in generation “n” produces some random number of individuals in generation n + 1, according to a fixed probability distribution that does not vary from individual to individual. Branching processes are used to model reproduction. A central question in the theory of branching processes is the probability of ultimate extinction, where no individuals exist after some finite number of generations. Keywords: branching process, stochastic process, discrete time markov chain

Abstract

The research presented in this article aims to identify “plague” botnet communication pattern, with the aid of Wireshark Packet Analyzer as proof of concept (PoC) towards unique communication pattern analysis between infected host and botnet. The research is conducted on public IRC (Internet Relay Chat) network, specifically at the opened domain for botnet research, that is, irc.accesox.net. COMODO Internet Security also used for determining files downloaded by the botnet to identify whether there any malware or not. The observation is done on 60 captured packets, which then the TCP stream excerpt and the protocols hierarchy statistic from those packets being analyzed. Based on the analysis of TCP stream excerpt and the protocols hierarchy statistic, the communication pattern between bot, botmaster, and infected host are known. Wireshark could show the data inside the TCP stream excerpt and all captured protocols. The conducted analysis on TCP stream excerpt and protocols hierarchy statistic is based on RFC 2812 (Internet Relay Chat: Client Protocol – IETF Tools). The analysis on TCP stream excerpt and protocols hierarchy statistic yield botnet activity information for the next step of the analysis of botnet attack, which is dataset and prediction model building. The prediction model can then be implemented to predict whether network traffic is safe or harmful.       Keywords: botnet, COMODO internet security, Internet Relay Chat (IRC), RFC 2812, Wireshark

Abstract

Dalam suatu citra, banyak informasi yang bisa didapat, dan informasi tersebut dapat digunakan untuk menyederhanakan analisis citra, misalkan identifikasi objek dan ekstraksi warna. Citra memiliki citra warna, salah satunya adalah citra warna model RGB. Selain itu sebuah citra juga memiliki citra skala keabuan (grayscale) memiliki unsur-unsur yang terdiri dari entropy, kontras, energi, homogenitas, skala keabuan dan standar deviasi. Unsur-unsur citra RGB dan skala keabuan tersebut dapat dijadikan masukan ke sistem jaringan syaraf tiruan, sehingga sistem jaringan syaraf tiruan (JST) dapat mengenali atau membedakan suatu objek berbentuk citra berdasarkan warnanya. Sebagai alat bantu dalam mengolah citra dan membuat sistem jaringan syaraf tiruan, digunakan software MATLAB versi 7.5.0.342, karena terdapat toolbox untuk mengolah JST yang sangat membantu dan mempermudah dalam pembuatan sistem ini. Kata kunci : citra, warna, keabuan, jaringan syaraf tiruan
