Abstract

Dalam rangka meningkatkan taraf hidup masyarakat di Kabupaten Jayapura, sarana dan prasarana transportasi darat dianggap memegang peranan yang sangat penting guna memperlancar arus mobilitas barang dan jasa, serta dapat pula membuka keterisolisiran masyarakat setempat dikarenakan jalan penghubung yang masih sulit untuk dilalui oleh kendaran. Penelitian ini bertujuan untuk memperoleh hasil desain perkerasaan pada ruas jalan HPH SPIII ? SPIV Distrik Yapsi Jayapura dengan panjang 5000 meter. Sehingga jalan yang direncanakan dapat memudahkan mobilisasi serta hubungan transportasi dari daerah ke kabupaten bahkan sampai ke pelosok-pelosok desa yang terpencil sekalipun. Metode yang digunakan dalam studi ini adalah metode Bina Marga. Perkerasan lentur (flexiblepavement) terdiri dari lapisan-lapisan yang berfungsi untuk menerima beban lalu lintas dan menyebarkannya ke lapisan di bawahnya. Konstruksi perkerasan lentur (flexiblepavement) terdiri dari empat lapisan yaitu lapisan permukaan (surface), lapisan pondasi atas (basecourse), lapisan pondasi bawah (subbase), dan lapisan tanah dasar (subgrade), sehingga diperoleh kesimpulan bahwa susunan tebal perkerasan terdiri dari lapisan permukaan (surface) menggunakan Laston dengan tebal 10 cm, lapisan pondasi atas (basecourse) menggunakan batu pecah kelas B dengan tebal 20 cm, dan lapisan pondasi bawah (subbase) menggunakan sirtu kelas B dengan tebal 10 cm dan mampu melayani beban selama umur rencana 10 tahun.

Abstract

Gender representation is one of the most prominent subjects of discussion in American society. Fairy tales as one of the first cultural products consumed by the American society are a medium with an influential presence in the issue. They provide gender representations and convey the idea of masculine and feminine- myths of how to be men and women. However, in 20th century, many movies are changing the perspective by presenting women and action and break the traditional myth. In the same year, a movie entitled Snow White and the Huntsman appears as the remake of the written fairy tale Snow White in the form of an action-adventure movie. To move the discussion further, this research examines how the idea of women as victims of violence in the movie is maintained. A number of disciplines in the forms of theory and approach are used to analyze the data. It also applies gender theories and Barthes's semiotic theory in answering the research question. As a result, it is found that the character Snow White and a number of other women characters still become victims of violence. The representations are also still associated with the traditional ideas of women.

Abstract

This research demonstrates the revealing of an advanced encryption standard (AES) encryption device key. The encryption device is applied to an ATMEGA328P microcontroller. The said microcontroller is a device commonly used in internet of things (IoT). We measured power consumption when the encryption process is taking place. The message sent to the encryption device is randomly generated, but the key used has a fixed value. The novelty of this research is the creation of a systematic and optimal circuit in carrying the differential power analysis or difference of means (DPA/DoM) technique, so the technique can be applied in key revealing on a microcontroller device by using 500 traces in 120 seconds.

Abstract

Cryptography is a science of creating a secret message and it is constantly developed. The development consists of attacking and defending the cryptography itself. Power analysis is one of many Side-Channel Analysis (SCA) attack techniques. Power analysis is an attacking technique that uses the information of a cryptographic hardware’s power consumption. Power analysis is carried on by utilizing side-channel information to a vulnerability in a cryptographic algorithm. Power analysis also uses a mathematical model to recover the secret key of the cryptographic device. This research uses design research methodology as a research framework started from research clarification to descriptive study. In this research, power analysis attack is implemented to three symmetrical cryptographic algorithms: DES (Data Encryption Standard), AES (Advanced Encryption Standard), and BC3 (Block Cipher 3). The attack has successfully recovered 100% of AES secret key by using 500 traces and 75% DES secret key by using 320 traces. The research concludes that the power analysis attack using Pearson Correlation Coefficient (PCC) method produces more optimal result compared to a difference of means method.

Abstract

The destruction caused by channel can be seen by the existence of Amplitude and Phase Shift. By using the 6 Ways Diversity Combining method (6 Antennas/Receivers), it is expected that the disruption caused by Amplitude and Phase Shift can be suppressed as small as possible. In addition, by using diversity combining module, we will get a large SNR output which has a value sum of SNR of each diversity path. The design of Diversity combining module begins with MATLAB functional design as a big picture of the whole system. Subsequently, it will be made the hardware based on the MATLAB functional. This architectural design that will be the cornerstone in the MATLAB bit precision manufacturing. Then MATLAB bit precision will be designed as the foundation of the VHDL design. Diversity combining the output module meets the standards specified by the DVB consortium. In the hardware (FPGA) test results of diversity combining, the maximum working frequency is 44.56 MHz which has shown that is qualified with the standard sampling clock (9.142 MHz). This design also needs 4% of total FPGA Cyclone II 484I8 combinational units which is 2499 units and it needs also 3% of total register of FPGA Cyclone II 484I8 which is 1720 register units.

Abstract

Cryptography is a very important aspect in data security. The focus of research in this field is shifting from merely security aspect to consider as well the  implementation  aspect.  This  paper  aims  to  introduce  BC3  algorithm  with focus  on  its  hardware  implementation.  It  proposes  an  architecture  for  the hardware  implementation  for  this  algorithm.  BC3  algorithm  is  a  secret-key cryptography  algorithm  developed  with  two  considerations:  robustness  and implementation  efficiency.  This  algorithm  has  been  implemented  on  software and has good performance compared to AES algorithm. BC3 is improvement of BC2 and AE cryptographic algorithm and it is expected to have the same level of robustness and to gain competitive advantages in the implementation aspect. The development of the architecture gives much attention on (1) resource sharing and (2)  having  single  clock  for  each  round.  It  exploits  regularity  of  the  algorithm. This architecture is then implemented on an FPGA. This implementation is three times smaller area than AES, but about five times faster. Furthermore, this BC3 hardware  implementation  has  better  performance  compared  to  BC3  software both in key expansion stage and randomizing stage. For the future, the security of this implementation must be reviewed especially against side channel attack.

Abstract

Block ciphers are used to protect data in information systems from being leaked to unauthorized people. One of many block cipher algorithms developed by Indonesian researchers is the BCF (Block Cipher-Four) - a block cipher with 128-bit input/output that can accept 128-bit, 192-bit, or 256-bit keys. The BCF algorithm can be used in embedded systems that require fast BCF implementation. In this study, the design and implementation of the BCF engine were carried out on the FPGA DE2. It is the first research on BCF implementation in FPGA. The operations of the BCF machine were controlled by Nios II as the host processor. Our experiments showed that the BCF engine could compute 2,847 times faster than a BFC implementation using only Nios II / e. Our contribution presents the description of new block cipher BCF and the first implementation of it on FPGA using an efficient method.

Abstract

This research aims to examine the self-representation of sensuous female influencers in Indonesia, specifically a 20-year-old female Javanese influencer who lives in Surakarta, on Instagram, and how the influencer publicly presents herself in front of the audience. Relying on Goffman’s Dramaturgical approach, this study provides thorough insights into the frontstage and backstage behavior of the sensuous female influencer and the representation of the influencer on the frontstage. Employing Charles Sanders Peirce’s semiotic triadic model (1931), the data obtained from Instagram were analyzed by understanding the representamen, the interpretant, and the object of the data. Then, to gain a more detailed understanding, the data collected from in-depth interviews were also scrutinized. This study shows that there is an act of rebellion of being against society's norms of modesty as the influencer constantly acts in a sexualized manner in public and daily activity. While previous studies mostly examine the phenomenon of the sexualized manner of women in hyper-sexualized cultures/Western cultures, this study provides an understanding of the sexualized manner of a sensuous Javanese female influencer in the area where people do not find self-sexualization behavior as common or prevalent.
