Abstract

The Caesar Cipher algorithm is one of the classical cryptography methods used to secure messages with letter substitution techniques based on certain shifts in the alphabet. This study aims to analyze and implement this algorithm in message security in order to understand its effectiveness and limitations in the world of information security. The methods used include encryption and decryption processes with character shifts according to the specified key. Implementation is carried out using the Python programming language as a case study. The results of the study show that Caesar Cipher is effective in providing basic security for messages, but has significant weaknesses against brute force attacks because it only has 25 possible keys. Therefore, this algorithm is more suitable for use as a basis for learning in the field of cryptography or combined with other security methods to increase its level of security.

Abstract

Kehidupan pesantren yang bersifat komunal menuntut penerapan Perilaku Hidup Bersih dan Sehat (PHBS) secara konsisten. Kegiatan pengabdian ini bertujuan meningkatkan pemahaman dan kesadaran santri terhadap PHBS, mengidentifikasi faktor yang memengaruhi penerapannya, serta mengembangkan model pendampingan PHBS berbasis nilai-nilai pesantren. Kegiatan dilaksanakan di Pondok Pesantren Sunan Drajat menggunakan pendekatan partisipatif-edukatif melalui penyuluhan dan pendampingan harian. Data dikumpulkan melalui pre-test dan post-test, observasi, serta wawancara singkat. Hasil kegiatan menunjukkan peningkatan pemahaman santri dan perubahan perilaku positif dalam menjaga kebersihan diri dan lingkungan asrama. Kegiatan ini menghasilkan model pendampingan PHBS yang kontekstual dan berpotensi berkelanjutan dalam mendukung terwujudnya pesantren sehat.

Abstract

Sunan Drajat Islamic Boarding School, as an Islamic educational institution, has a strategic role in shaping the character and competencies of students, which is highly influenced by the quality of services provided by its administrators. This study aims to optimize student services through a capacity building-based mentoring model for boarding school administrators. The research design employs a collaborative participatory approach oriented toward action and continuous improvement. The methods include training, intensive mentoring, and evaluation based on structured instruments, involving 42 active administrators of Sunan Drajat Islamic Boarding School in Lamongan during the period of January–March 2025. The results indicate significant improvements in managerial competence (52% to 78%), interpersonal communication (58% to 82%), student satisfaction (49% to 71%), understanding of institutional vision (61% to 85%), and conflict management skills (44% to 69%). These findings demonstrate that capacity building-based mentoring is effective in improving the quality of administrators, which directly impacts the optimization of student services.
