CMK company is a retail company that sell and distributes miniature vehicle items to small stores. CMK has several branches in various countries that use for operational and storage warehouse. This company faces the problem for analysing sales to decide the useful strategy since this company only uses Online Transaction Processing (OLTP) database. This study implements Online Analysis Processing (OLAP) database and data warehouse to provide useful information for this company by using the nine-step method designed by Kimball & Ross. The data will be performed into dashboard to make easier for CMK Company to analyze data. Furthermore, many useful information can be provided in short and efficient time.

The role of climate can be affected by plants. The weather can accelerate and multiply the existence of various plant pests and diseases, accelerate the growth and development of grass among plants, and encourage the emergence of infection and significant damage to plants. The elements of climate that affect the growth of plants are one of them is rainfall. In this paper, we performed the simulation using the non-parametric penalized spline (PSPLINE) method and studied the effect on rice production in Lampung. It can be concluded that the increasing fluctuation, frequency, and intensity of climate anomalies in the last decade caused by the ENSO phenomenon have an impact on changes in distribution patterns, intensity, and period of the wet season so that the start of the rainy season and the dry season becomes too late. As a result, there is a seasonal shift from normal average conditions that can ultimately have severe implications for food crops. In a nutshell penalized spline gives high accuracy with R 2 = 96.227% and MAPE = 1.62%. © 2018 Institute of Physics Publishing. All rights reserved.

Procedia computer science 2017年 116卷 381-392页

作者： Zulfany Erlisa Rasjid Benfano Soewito Gunawan Witjaksono Edi Abdurachman Doctor of Computer Science School of Computer Science Bina Nusantara University Binus Graduate Program Bina Nusantara University Binus Graduate Program School of Statiatics Bina Nusantara University

Digital forensic tool is a software used by digital evidence investigators to extract data and information from a digital evidence. The integrity of the digital evidence must be maintained through the chain of custody in order to be admissible in court. Most digital extraction tool use either MD5 (Message Digest) or SHA (Secured Hash Algorithm) hashing to check the integrity of digital evidence. The hashing algorithm has been found to have a weakness known as collision in which two different messages have the same hashing values. Although the probability of producing such weakness is very small, this collision can be used to deny the usage of the evidence in court of justice. After the first collision has been found, many cryptanalysts have tried to explore various methods to detect the collisions with shorter and efficient time. This paper is to review the existing methods in digital forensic tools that have been used to create a collision attacks in digital evidence.

This paper describes the maturity degree evaluation of Information Technology Governance at Information System Centre (PSI) in STMIK Mikroskil to measure IT Governance and the success of IT-based facilities that cannot be measured yet. The evaluation measured by using Process Assessment Model (PAM) from Framework COBIT 5 which refers to the specified 10 domain process. Data is collected from 36 returned-questionnaire of 47 distributed-questionnaire. Data is analyzed using Framework COBIT 5, Slovin method is used to determine the number of valid data samples, and Rating Scale Formula operated to determine the scale of capability level for each selected domain. From the evaluation results known 1 domain has been achieved the expected capability that is DSS05 at Level 4, and other process domains still exist under the expected capability level, then the results are used to establish improvement recommendation based on Framework COBIT 5.

Foreground segmentation is one of moving object detection techniques of computer vision applications. To date, modern moving object detection methods require complex background modeling and thresholds tuning to confront illumination changes. This paper proposes an adaptive approach based on non-overlapping block texture representation. It aims to design a computationally light and efficient solution to improve the robustness of detection. We evaluate our proposed method on internal and public sequences and provide the quantitative and qualitative measurements. Experimental results show that the proposed method can improve the results of previous method and suitable for real-time challenges.

The success of learning in a classroom that uses supporting media demands lecturer activity. The level of activity of lecturers in class and using learning media such as Smart lecturer can be measured using a fuzzy logic approach. This study aims to measure the level of active lecturers using the approach, namely: Mamdani and Sugeno method. Stages of lecturer activity measurement by forming a fuzzy set, composition rules as many as 24 rules and the defuzzification process using the centroid method that produces the level of activity of each is low, medium and high. Based on 173 lecturer activity data, the results of the Mamdani method indicates low 66%, medium 31%, and high 3%. While the Sugeno method produces a level of activity low 75%, moderate 17%, and high 8%. Therefore, Mamdani method is more suitable for the calculation because the spread of results is relatively evenly distributed at each level.

Recently, the Indonesian government requires auditors, the need for auditors around 40,000 auditors in 2016, currently has only about 10,800 auditors, however, the lack of the auditors impacting the risk of financial loss for the state. Referring to the problem, this experimental research was conducted. The experiment of the research was conducted two times and the audit topic is a compliance audit in the year 2017 and year 2018. The goal of this research is to know, can the stakeholder act as an IT and general compliance auditor? The experiment was conducted by 8 university students in 2017 and 19 university students in 2018, and the supporting tools of audit activities the university student use the smartphone to capture the object as evidence. The experiment results with descriptive method show university students can act as an auditor and found several pieces of evidence that might cause future impact to the institution.

The transfer of land has an impact on the decreasing of the agricultural land area, so it is necessary to plan the right cropping pattern as an effort to increase the productivity of agricultural cultivation. Also, Climate is one of the factors influencing the determination of cropping pattern in a region. Analysis of climatic characteristics in the determination of cropping pattern not only based on oldeman climatic classification. At the same time, the study of groundwater availability for plants and climogram of climatic elements is needed in determining planting schedule which is suitable for planting and determination of irrigation water supply, either the right amount of time. This study aims to identify and build spatial of the oldeman climate classification. It also determines the cropping pattern for seasonal crops based on the calculation of water balance and climogram (rainfall and air temperature) in each type of climate oldeman district of Cirebon and surrounding areas. Data used monthly rainfall data period 1981-2010 from BMKG Jatiwangi station and air temperature data, plant coefficient and the base map of Cirebon region. The analysis method includes classification of Oldeman climate type, spatial data processing, water balance calculation by Thorntwaite & Matter method and making climogram (rainfall and temperature) with: k = p0 + p1/FC;p0 = 1.000412351;p1 = -1.073807306 and determination of planting pattern of each type of oldeman. © 2018 Institute of Physics Publishing.
