Abstract

This journal is devoted to the analysis of the Stuxnet malware known as (Win32 / Stuxnet) which has suddenly caught the attention of virus researchers in the last three years. In this journal, an overview of attacks targeted at the SCADA (Supervisory Control And Data Acquisition) system and PLC (Programmable Logic Controller) will be explained as the main targets of Stuxnet. Besides that, it will also explain the history of the development / variant of Stxunet and the prevention that can be done against the Stuxnet threat.

Abstract

The development of technology today, especially computer technology has been very advanced. Including in Indonesia have many computer products that are marketed with various types, prices and specifications. To address it then we as consumers should be careful in choosing and buying the hardware components. So we are not deceived by the cheap price offered but also must be more thorough on the quality of goods offered. In general, the solution if the consumer experiencing performance problems in the software is to install the computer on the computer service. Installation costs generally range from RP 50,000 - RP 75,000. Imagine if the consumer in a year to install 5 times, the cost incurred around RP 250,000 - RP 375,000. Though the computer installation process is very easy to learn and just need accuracy in the process of data format. Hardware and operating system specifications are still not realized by the public is the most important part in the performance of a computer. Knowledge of hardware specifications is crucial to the performance of a hardware, as well as operating systems that do not have viruses or malware can also improve computer performance. Based on that, direct exposure and practice will be given maximally to provide the required information

Abstract

Kemacetan adalah situasi atau keadaan tersendatnya atau bahkan terhentinya lalu lintas yang disebabkan oleh banyaknya jumlah kendaraan melebihi kapasitas jalan. Dampak dari kemacetan ini mengakibatkan pemborosan waktu, pemborosan bahan bakar, polusi udara, tingginya tingkat stress pengguna jalan, tingginya tingkat kecelakaan dan sebagainya. Kemacetan banyak terjadi di kota – kota besar, terutamanya yang tidak mempunyai transportasi publik yang baik atau memadai ataupun juga tidak seimbangnya kebutuhan jalan dengan kepadatan penduduk. Kemacetan lalu lintas menjadi permasalahan sehari – hari terutama di kota medan. Di kota medan sendiri, waktu terjadinya kemacetan secara umum dapat dibagi menjadi tiga waktu yaitu pagi (06.30 – 08.30), siang (12.00 – 13.30) dan sore (16.00 – 19.00). Dalam mengantisipasi permasalahan tersebut maka pada jurnal ini diusulkan berupa solusi dengan memilih jenis kendaraan misalnya : sepeda motor, mobil pribadi, angkot dan taksi dengan taksiran waktu tempuh yang bersesuaian dengan jenis kendaraan yang dipilih. Dalam proses pemilihan jenis kendaraan ini diterapkan fuzy linier programming untuk memberikan pemilihan yang optimal dalam mengantisipasi kemacetan yang terjadi. Hasil akhir dari penelitian ini diperoleh beberapa jenis kendaraan yang terbaik untuk mengatasi waktu kemacetan yang terjadi.

Abstract

Plastic is a polymer material widely used as a food and beverage packaging material due to the lightness and easy to use. The selection of quality plastic raw materials from industries engaged in plastic production are greatly affects the products produced. However, there are some mistakes occurred due to the selection process is carried out subjectively without any consideration, resulting in material losses for the company. The difficulty in determining superior plastic raw materials is one of them. The study attempts to select the best plastic raw materials using the Simple Additive Weighting (SAW) method. The research use five criteria for types of raw materials, namely: price, quality, production speed, plastic waste, location. Then, the plastic seeds brands used in this study are: Poly-max, El-pro, Titan, Polytan, and Trilene. The result of the study shows various result and present which seeds is the best to be used in the company.

Abstract

Of the several animals that we know, the cat is one of the most popular pets in today's society. However, in order to keep the pet cat in good health, cat keeper must pay more attention to the food schedule otherwise the cat will be susceptible to disease, so it can harm the cat itself. In today's modern era, many things can be designed to make activities easier. One of them is the design of a prototype automatic cat feeder. The purpose of this research is to design and make an automatic cat feeding device using Arduino Uno R3 as the brain in this series which then uses Arduino IDE software and C++ programming discussion to input the data that will be needed. Furthermore, this tool will also be directly connected to the RTC (Real Time Clock) as a benchmark for the hour and date and the servo motor as a valve controller, so that the feeder will open according to the input schedule. This tool also uses the GPRS Shield 800L as a sender of SMS notifications when the prediction feed is running out. Finally, this one set of tools also uses a step down module which can be used as a voltage adjustment for the feeder. This tool can later be useful, especially for cat shelter owners/keepers because it can provide feed according to a time and schedule whose own dose can be inputted based on age. The advantage of this tool is that it can last for approximately 2 hours without electricity (possibly when the power goes out) specifically for sending notifications.
