This study aims to develop an authentication alternative by applying the Histogram shifting steganography method. The media used for authentication is image media. Histogram shifting utilizes the histogram of an image to insert a secret message. The developed authentication has implemented the Histogram shifting to insert user credentials into the carrier image. Users can use the steganographic image to log into their accounts. The method extracts the credentials from the image during the login. PSNR test of the steganographic images produces an average value of 52.52 dB. The extraction capability test shows that the method can extract all test images correctly. In addition, this authentication method is also more resistant to attacks common to password authentication.

Writing is an inseparable activity from everyday human life. Writing skills can be fostered from diligent reading. One of the reading media as well as the media for pouring student work is mading. Mading is a vehicle for applying students' abilities, especially in the field of writing. MI Manbaul Ulum Karangduren is a school located in Malang Regency. The school does not yet have a class bulletin board containing student work. Thus, the opportunity for students to develop their creativity in writing is hampered. Efforts are needed to improve writing skills for students to build a reading culture. One way is to publish bulletin as a teaching aid and coaching. Through bulletin board, it is hoped that students can have creativity in writing. The results of community service activities show that students' writing skills have improved. The average value of N-Gain Creativity Test scores 0.73 in the high category. This shows the level of effectiveness of the treatment has a high effect on the post test.

Abstrak Keterampilan membaca permulaan siswa masih rendah dikarenakan kurangnya keterampilan guru dalam mengolah pembelajaran menjadi menarik, hal ini menyebabkan siswa kurang antusias dalam membaca sehingga siswa lebih asyik bicara sendiri dengan teman sebangkunya. Penelitian ini memfokuskan pada: apakah ada peningkatan dalam membaca setelah menggunakan metode suku kata berbasis media kartugambar dan Apakahfaktor yang mempengaruhi dalam keterampilan membaca permulaan. Jenispenelitian ini adalah penelitian tindakan kelas sedangkan sabjeknya ialah seluruh siswa kelas 1 MI Nurus Shibyan Ambat dengan jumlah 18 siswa. Metode yang digunakan dalam pengumpulan data adalah wawancara, observasi, tes dan dokumentasi. Dalam membaca permulaan peneliti penggunaan metode suku kata berbasis media kartu gambar dari hasil tersebut terlihat adanya peningkatan keterampilan membaca permulaan pada siswa. Hal ini dibuktikan pada saat sebelum diberi tindakan nilai rata-rata dari seluruh siswa masih rendah yaitu 45,27, dan presentase ketuntasan klasikalsiswa 16,67%. Pada siklus I setelah diberi tidakanya itu dengan menggunakan metode suku kata berbasis media kartu gambar nilai rata-rata siswa meningkat menjadi 57,5 dan presentase ketuntasan klasikal sebesar 27,78%. pada siklus II nilai rata-rata siswa meningkat menjadi 67,5 sedangkan presentase ketuntasan siswa menjadi 55,56%. Dan pada pelaksanaan siklus III nilai rata-rata siswa meningkat menjadi 78,88 dan peningkatan presentase ketuntasan siswa mencapai 83,33%.  Kata Kunci: Membaca Permulaan, Suku Kata Berbasis Kartu Gambar Abstract Reading skills at the beginning of students are still low due to the lack of teacher skills in processing learning to be interesting, this causes students to be less enthusiastic in reading so that students are more engrossed in talking to themselves with their peers. This study focuses on: is there an increase in reading after using the syllabic media-based syllable method and what are the influencing factors in early reading skills. This type of research is classroom action research while the subject is all grade 1 students of MI NurusShibyanAmbat with a total of 18 students. The methods used in data collection are interviews, observation, tests and documentation. In reading the beginning of the researcher the use of the syllabus-based media method of the image card shows that there is an increase in students' beginning reading skills. This was evidenced at the time before being given an action the average value of all students was still low at 45.27, and the percentage of classical completeness of students was 16.67%. In the first cycle after being given the act of using syllables based on the media card the average value of students increased to 57.5 and the percentage of classical completeness was 27.78%. in cycle II the average value of students increased to 67.5 while the percentage of student completeness to 55.56%. And in the implementation of the third cycle the average value of students increased to 78.88 and the percentage ofstudentscompleteness reached 83.3%. Keywords: Reading Beginning, Syllables Based On Picture Cards

AbstractThis paper contains a brief description of new approach regarding LSB steganography. The novelty of the method resides in the combination of LSB (Least Significant Bits) steganography with some primitives of the pixel-sieve/bit-sieve cryptographic method. In short, we propose to use two or more carrier images and the sieving algorithm, borrowed from the pixel sieve primitive, to determine which carrier image will receive the next set of bits of the secret message. While in classic LSB steganography the secret message must be encrypted prior to embed the information into the carrier image, in our proposal the message is scrambled between the shares in a pseudo random way. An attacker will need all the carrier images and the sieving key in order to reconstruct the original message. Also we recommend an alternative method in which instead of simply replacing the last bit/bits we use them as XOR keys to further enhance the security. Keywords: steganography, cryptography, secret sharing; visual cryptography, LSB.

Substitution Cipher

In this paper we present a technique for secure communication between two parties Alice and Bob. We use both cryptography and steganography. We take image as the carrier to use steganography. By using our own substitution cipher called two square reverse we encrypt the secret information. Then the cipher text of the secret information is embedded into the carrier image in LSB (least significant bit) minus one position of some selected bytes. The byte selection is done depending on the bit pattern of the secret information. Thus the embedding locations are dependent on the secret message. So the intruder will face difficulties to locate the bits. After embedding the resultant image will be sent to the receiver, the receiver will apply the reverse operation what the sender has done and get the secret information.

Abstract Science instruction with conceptual material is often less attractive to students. It’s considered less attractive and difficult to understand than it’s necessary to develop interactive learning media for instruction. This study aims to develop the media and see its effect on increasing student interest in science instruction by using the Encyclopedia of Classification of Living Things through the demonstration method. This research was conducted on grade VII students at Madrasah Tsanawiyah 4 Ponorogo in the 2019/2020 school year. The type of research used is descriptive quantitative research. Data collection by filling out a questionnaire to measure students' interest in instruction. The results showed that there was an increase in student interest in instruction after using the Encyclopedia Media of Classification of Living Things. The average value obtained from before instruction was 74.76 while the average score obtained of post instruction was 75.52. Based on the analysis of these data, it can be concluded that there is an increase in student interest in science instruction by using encyclopedia media in classification of living things material.
