Abstract
In this paper, the wideband planar sleeve antenna with two sleeves on the upper side and two sleeves on the bottom side are analyzed numerically. In the previous study, the wideband planar sleeve antenna is used at frequency 3.5GHz. The purpose of this research is addressed to analyzed the wideband planar sleeve antenna in the range frequency of 400-4000 Mhz by using WIPL-D EM Simulator by adjusting the antenna parameter. The antenna upper sleeve, lower sleeve, the length of the antenna and the distance between the lower and upper sleeves are adjusted. The result shows that the wideband planar sleeve antenna is achieved. When the length of the upper sleeve is increased, the antenna will work on lower frequency but the return loss slightly reduced, the same effect will be gained by increasing the lower sleeve size, but its not affecting the lower frequency. When the antenna length is increased, the return loss of the antenna is reduced. Furthermore, the distance between lower and upper sleeve affects the return loss characteristic. This is indicated that by adjusting the length of the antenna parameter, the antenna is applicable for many systems, such as television system and the ISM system.

Abstract
Indigofera zollingeriana is a feed that has high crude fiber content so it is difficult to use for poultry feed. The fermentation process using fungus is expected to overcome this problem. The study aimed to determine the interaction between dose and fungi kinds, with the length of fermentation on the protein and crude fiber content of I. zollingeriana. Another goal is to determine the optimum conditions for fermenting I. zollingeriana. The method used a Completely Randomized Design (CRD) factorial pattern. The first factor consisted of 6 levels of the different fungi dosages, namely 0.1%, 0.2% and 0.3% Trichoderma harzianum; 0.1%, 0.2% and 0.3% Aspergillus niger. The second factor was four levels of the duration of fermentation: 24 hours, 48 hours, 72 hours and 96 hours. All treatments were repeated twice. The experimental data were tested by F test, then Duncans analysis was carried out. The results showed that there was an interaction between dose and fungi kinds with the length of fermentation. The optimal condition for fermenting I. zollingeriana with T. harzianum fungus was at a dose of 0.3% and 96 hours fermentation time. This treatment gave the increasing of protein content and reducing crude fiber content.

Abstract
This paper presents the development of a supportive tool for Computer Security related Classroom while taking advantage of the User-centered Design Canvas. The proposed supportive tool was developed to support both lecturer and students to manage the submission and scoring system on the Computer Security class related. The User-centered design itself was widely used as an approach to software development in order to achieve better design on the User Interface and the User Experience. Adopting Bussiness Model Canvas, the User-centered Design Canvas was introduced as an acceleration tool for rapid prototyping and ensure the effectiveness and efficient manner for the sake of user satisfaction. As the results from the questionnaire, more than 85% of users express the benefits of the current development supportive tool. Also from the Log Metric Analysis, users have completed a designated task in few minutes with minimum repetition. This indicates that the developed supportive tool is easy to use and shows the effectiveness of the User-Centered Design Canvas for rapid prototyping.

Abstract
The use of e-Samsat services as a means to facilitate the process of paying motor vehicle tax has not made a significant contribution. This is due to the lack of introduction to the community, especially in the East Java region, that the benefits of e-Samsat can be used optimally. This study aims to analyze the factors that influence the use of e-Samsat services. this research can provide recommendations to policy makers to improve East Java e-Samsat services, especially payment for Motor Vehicle Taxes. Methods of collecting data by distributing questionnaires, and analyzing data using the Structural Equation Modeling (SEM) approach using variables such as Trust, Awareness and Intention to Use. The results of the study show that the Trust and Awareness variables directly or indirectly affect the intention to use East Java e-Samsat services.

Abstract
Introducing traditional musical instruments to the students in the digital era needs to be facilitated by utilizing several devices, such as a computer keyboard or a laptop as music controllers. By utilizing a computer keyboard as a music controller, the students can recognize the characteristics of sounds, and play melodies from traditional musical instruments in simpler ways. Therefore, this research aims at describing the utilization of Scratch application in controlling music production through a computer keyboard. Following are steps taken: (1) install the Scratch, (2) make the sound buttons, (3) input the sound from traditional musical instruments, and (4) set the sound buttons according to computer keyboard. The production of the music controller has resulted in teaching media used for introducing the sound of traditional musical instruments and playing a series of melodies based on the availability of tone structures in a computer keyboard. The melodies can be played in single-tone, two-tone, and/or more (chord) patterns. To conclude, the utilization of the Scratch as music controllers has potentially facilitated the introduction of traditional musical instruments in the digital era to the students.
