Saat ini informasi telah menjadi bagian yang sangat penting dalam suatu aktivitas. Sebagai contoh,dalam suatu proses pengambilan keputusan, informasi dapat mengurangi ketidakpastian dan dapatmenciptakan alternatif keputusan yang lebih baik. Kerahasiaan dari suatu informasi yang memilikinilai sangat penting atau sensitif dapat dilindungi dengan menggunakan kriptografi. Untuk melindungiinformasi yang berupa berkas diperlukan suatu perangkat lunak yang dapat melakukan prosesenkripsi terhadap berkas-berkas. Perangkat lunak tersebut menggunakan suatu algoritma kriptografiuntuk mengenkripsi berkas. Algoritma kriptografi yang digunakan pada penulisan in; adalah DataStandar enkripsi atau disingkat DSE. DSE mengenkripsi data dalam ukuran 54-bit denganmenggullakan kunci berukuran 55-bit. Blok data 54-bit diperoleh dengan mengambil byte-byte danmengubahnya ke dalam bit. Blok bit data yang telah diproses selanJutnya diubah kembali ke dalambyte dan disimpan pada berkas hasil bserta dengan kunci yang digunakan. Berkas hasil terse butmemiliki ekstensi .ECR. Kunci yang disimpan pada berkas hasil tersebut dienkripsi denganmenggunakan MD5 (Message Digest 5). Algoritma DSE yang diimplementasikan pada perangkatlunak menggunakan mode operasi Cipher Block Chaining. Basis data digunakan untuk meny'mpandaftar pengguna yang dapat menggunakan perangkat lunak terse but beserta kata sandi logonnya.Dengan digunakannya penggunaname dan kata sandi logon untuk mengakses perangkat lunak makaakan meningkatkan keamanan dari data terenkripsi dan perangkat lunak itu sendiri. Selain itukeamanan data terenkripsi lebih tinggi karena algoritma DSE menggunakan mode operasi CBCsehingga ciphertext yang dihasilkan akan selalu berbeda untuk data yang sama. Karena dapatmengenkripsi semua tipe berkas maka perangkat lunak terse but memiliki fleksibilitas dalammelindungi informasi yang ada.Kata kunci : Enkripsi, Data Standar enkripsi, Kriptografi, Visual Basic.

UMKM MAPAN is one of the UMKM communities consisting of 300 UMKM entrepreneurs who are currently developing and located in the Depok area. These UMKM provide a wide variety of products to be marketed. In marketing these products, these UMKM group still uses the conventional method, is still by face-to-face with the buyer, so they have to rent a place first and are still limited in marketing online. This method has many weaknesses, such as the high cost of renting a place and the difficulty of finding a strategic location to market the product. Therefore, in this study, an e-commerce marketplace web system was created that could accommodate 300 UMKM MAPAN entrepreneurs in marketing their products. In addition, an automatic system for payment transactions on the UMKM marketplace was also created using the Horspool crawling method so that it could make it easier for UMKM entrepreneurs to print payment transaction reports. Based on the research results, the success rate of report printing is 100%. In this study, the complexity of the Horspool algorithm is O(n) with n is length of pattern while the time complexity of the Horspool algorithm is O(m+σ) with m is length of search string.

This research is motivated by the important role of teacher performance in the education and learning process, especially in determining student learning outcomes. Teacher performance is a complex factor and involves understanding students' situations and the ability to create a conducive learning atmosphere. Apart from performance, the compensation received by teachers can also influence creativity in teaching. Therefore, this research was conducted to analyze the influence of human resource management compensation and teacher performance on teacher creativity in Depok City Vocational Schools. Teachers as research objects were chosen because they have a strategic role in improving the quality of education. The research method used is a quantitative approach with multiple regression analysis. This research involved the entire population of vocational school teachers in Depok City, with a total population of 150 teachers. However, the samples taken were 90 teachers from various backgrounds including gender, education level and age. Data was collected through questionnaires filled out by respondents. Variables in this research include compensation, teacher performance, and teacher creativity. Hypothesis testing was carried out to determine the relationship between variables and see the significant influence that emerged between teacher compensation and performance on teacher creativity. The research results show that compensation does not have a significant effect on teacher performance. However, teacher performance has a significant influence on teacher creativity. Simultaneously, teacher compensation and performance have a significant influence on teacher creativity. These findings emphasize the importance of improving teacher performance in an effort to encourage creativity, and provide an illustration that even though compensation does not show a significant direct effect, attention is still needed in its management to support optimal performance.

The marosok is a tradition of buying and selling livestock using hand movements and facial expressions in the bargaining process. The marosok tradition has denotative and connotative meanings associated with Minangkabau culture. The purpose of this study was to determine the meaning of denotation and connotation of the marosok tradition with an ethnographic approach using Symbolic Interactionism Theory and semiotic analysis of Pierce. This research method is qualitative by conducting literature study and interviews using snowball sampling technique to M. Azhadi Dt. Bosa as key informant who directs researchers to Desmon Korina and Hadiyati who understand the marosok tradition in the Payakumbuh community. This study shows that the tools, hand movements and expressions in the marosok tradition have meanings that must be understood by the parties involved in the transactions. The sarong is a covering tool that shows marosok tradition is only carried out by men. Finger gestures indicate digits up to millions, increasing, or decreasing bidding. Expressions indicate approval or rejection of the offered price. The marosok tradition ends with handshake and smile between the seller and the buyer. The marosok tradition creates healthy competition where the prices are only known by the parties concerned. However, this process is not transparent, the buyer can only estimate the weight and condition of the livestock by seeing and touching the livestock directly, so the buyer must be very careful in choosing livestock with good quality. The marosok tradition must be maintained so that the media is needed to teach how to do marosok to the younger generation. Apart from being a buying and selling transaction, the marosok tradition can be used as an attraction for tourists to come to Payakumbuh.
