This study discusses the allocation of lecturers to apply courses by applying the concept of heuristic optimization using the Improved Symbiotic Organism Search (I-SOS) algorithm. The I-SOS Algorithm is a development of the previous algorithm, the Symbiotic Organism Search Algorithm, which is one of the latest metaheuristic methods inspired by the behavioral interactions seen between organisms in the universe. Optimizing the allocation of lecturers is very influential on the preparation of class schedules because scheduling a good course must be able to meet the needs of the parties directly related to the scheduling process. Conventional methods used today often cause problems in terms of efficiency and accuracy, imbalance of teaching load and inaccuracy in lecturer assignments requiring lecturers to take courses not in accordance with their interests and expertise.

The security and confidentiality of a message or document sent to other people must be guaranteed its confidentiality and security, so that the message or document is not misused by parties who do not have an interest in the message. Security and confidentiality of messages or documents can be kept confidential and secure by using cryptography. data security and confidentiality issues are very important from an information. Because of the importance of this information, the person concerned will question whether the authenticity of the information is still maintained or whether the information has been hijacked. So in the process of securing data and information with cryptography, of course it requires a qualified algorithm to maintain the confidentiality of the information, so that the purpose of this research is how to maintain the confidentiality of information by converting information into codes known only to the sender and receiver by using cryptographic techniques and steganography. Then the process of securing the data or information the researcher uses a combination of Caesar Chiper and Hill Chiper which is modified into Morse code then the resulting CipherText results will be saved into a JPEG file using the LSB (Least Significant Bit) Steganography method. The process of storing messages or ciphertext into image files will make it difficult for irresponsible people or cryptoanalysts to solve messages sent in the form of images.

The problem with TSP is an attempt to find the shortest distance traveled by a salesman in visiting each city without having to visit the same city more than once. The purpose of implementing the I-SOS algorithm in this case is to find the minimum distance traveled, a solution can be obtained after going through the calculation of the mutualism phase, commensalism phase, parasitism phase and predation phase. The resolution of TSP problems in the study begins with the process of identifying each city by providing a random value to represent each destination city. The random value used is between 0 and 1, the random results obtained will then be sorted with the provision that the smallest random value will be used as the initial for city A while the largest random value is used as the initial for city D. In the first random, the random value | 0.5 | 0.27 | 0.75 | 0.25 | the city representation of the random number is | C | B | D | A | or if the values are sorted, the city order will be obtained, namely A = 0.25, B = 0.27, C = 0.5 and D = 0.75, this process will continue until all the organisms defined in the ecosystem are formed

Penentuan jenis sampah dan harga jual yang sering berubah membuat para pengelola sampah kewalahan dalam memberi tahu warga, seringkali terdapat masalah terkalit jenis sampah yang dibeli oleh Bank Sampah Tarbiyatul Ummah yang harus menyortil ulang jenis-jenis sampah yang dijual ke para pemasok. Dan dalam pengolahan data bank sampah masih tulis secara manual dengn system dokumen yang tidak rapi, tulisan yang kurang jelas, dan data sering sekali terselip atau hilang. Maka Bank Sampah Tarbiyatul Ummah membutuhkan aplikasi yang dapat membatu pekerja anggota bank sampah baik dari penentuan jenis sampah dan juga membuat laporan yang akurat tentang penjulan di bank sampah. Khusunya terkait data jenis sampah anorganik yang diterima dari warga dan infomasi tabungan warga. Aplikasi penetuan jenis sampah non organic tersebut menggatikan proses penyortiran ulang jenis sampah dan juga nantinya memudah masyarakan dalam melakukan transaksi dan mengetahui harga jual dari jenis sampah yang mereka jual.

Queues are often encountered in daily activities. The queuing process is a process related to the arrival of customers at a service facility, waiting to get service until they finally get service and leave the service facility. Many queue models use single-server, single-phase system and multiple-server, single-phase system. Currently, there are still service facilities that have not utilized technology to provide convenience for the users. One way to improve service quality is by using a queuing system. The method applied in building this system is Prototype method. The prototype method consists of communication, which is the stage of data collection through the method of literature, observation, experiments which are described in use cases, activity and sequence diagrams as well as device requirements.
