Along with the development of technology and information today, data security is a problem that needs to be done to maintain the confidentiality of data or information both personally and within an organization. Cryptography is one of the sciences or arts that learns about how to secure data or information from irresponsible parties who want to destroy important data in the form of text and image files. This research, data security technique uses two algorithms, namely steganography to enter text in image media using LSB (Least Significant Bit) method and Binary XOR used to convert messages to binary with XOR keywords and generate pixel values of messages from 8 bits of images with LSB (Least Significant Bit). After encrypted the image will be sent to the user, and to view the original data, the user must decrypt the data with the message key and retrieve the LSB (Least Significant Bit) value, from the encrypted image.

Penerapan aplikasi umumnya bertujuan untuk mengatasi permasalahan yang cenderung ingin mendapatkan solusi dari hasil berupa konsultasi, diagnosis, estimasi, prediksi dan sejenisnya. Sama halnya penerapan dalam dunia kedokteran ataupun dunia medis, konsultasi, dan diagnosis sangatlah penting karena hasil diagnosis tersebut dapat mengantisipasi beberapa jenis penyakit dengan tepat, cepat serta akurat. Forward Chaining merupakan salah satu metode reasioning dan berfungsi sebagai mesin pengambil keputusan (inferensi) yang secara logis dapat di deskripsikan sebagai aplikasi pengulangan berdasarkan modus ponens. Forward chaining sebagai mesin inference bertugas untuk menemukan satu dari antecedent atau dalil hipotesa dari rules IF-THEN. Masalah-masalah yang akan diambil dalam pembangunan sistem pakar penyakit malaria adalah gejala-gejala yang mengindikasi pada penyakit malaria sedangkan pada identifikasi masalah akan diidentifikasi penyakit malaria pada manusia. Dengan sistem pakar ini, orang awam pun (pengguna) dapat menyelesaikan masalahnya atau hanya sekedar mencari suatu informasi berkualitas yang sebenarnya hanya dapat diperoleh dengan bantuan para ahli di bidangnya. Sistem pakar ini juga akan dapat membantu aktivitas para pakar sebagai asisten yang berpengalaman dan memiliki asisten yang berpengalaman dan pengetahuan yang dibutuhkan. Berdasarkan Hasil pengujian metode forward chaining menggunakan aturan pada basis pengetahuan berdasarkan fakta dari beberapa gejala penyakit malaria seperti malaria tropika, tertian, kurtana dana ovale yang ditemukan sudah sesuai dengan pengujian pada website sistem pakar diagnosis penyakit malaria.

consider other things such as avoiding the same or repeated schedules in one day, the number of teaching staff involved, and practicum subjects which in their implementation require a laboratory. The subject scheduling process at SMK Negeri 1 Tambolaka City is still carried out manually by Deputy Head 1 for the curriculum field, who currently uses Microsoft Excel software, which has the potential for errors and often requires correction before the schedule is implemented. Because the subject scheduling process is very important, a solution is needed in making subject schedules. Therefore, this research aims to optimize course schedules by applying a genetic algorithm to the course scheduling application. In this research, the process of preparing rosters for applied subjects was carried out at school using a web-based genetic algorithm method so that schedule collisions did not occur and the process was more optimal. In the experiment, the results of this subject scheduling application system consisted of several forms and menus, including a login form, department data menu, subject data, class data, teachers, hour ranges, special schedules, and the scheduling menu. Creating a teacher's teaching schedule using a genetic algorithm can produce a schedule automatically and systematically, thereby displaying the schedule for the day and time of each teacher's teaching schedule. The application of genetic algorithms in scheduling teacher teaching at SMK Negeri 1 Tambolaka City is a very optimal solution for scheduling, so that the possibility of similarities in the same teacher's teaching time and hours is very small.
