Tomato production in Indonesia is reduced because tomato leaves are stricken with disease. The main disease that often attacks tomato leaves is rotten leaves and bacterial patches or commonly called dry patches. Identification of tomato leaf disease is still done manually with human vision. The shortcomings of the method manually required a technology that is able to extract the texture of tomato leaf disease. One of them is by the process of extracting the texture of leaves with gabor filters, namely by using frequency and orientation parameters. Based on the results of the experiment obtained that the input parameter gabor filter with orientation of 90o with a combination of frequency 4 produces a fairly clear contrast. The process of extracting the texture of the leaf aims to get the magnitude value of the tomato leaf that will be used as inputs for the classification process. The svm algorithm grouped data that had the same characteristics into one class. Training data used 42 images and test data used 30 images, with the success rate of 83.33%.

Dalam hal akademis, Indeks Prestasi Kumulatif (IPK) merupakan tolok ukur prestasi pelajar termasuk mahasiswa. IPK itu sendiri adalah produk hasil dari proses belajar yang diperoleh dari berbagai bentuk evaluasi. Tingginya perolehan IPK mahasiswa kemudian menganggap bahwa mahasiswa dipandang memiliki kemampuan yang baik pula dalam setiap perkuliahan. Namun ternyata anggapan tersebut tidak sepenuhnya benar. Penelitian ini bertujuan untuk memprediksi tingkat kemampuan mahasiswa dalam perkuliahan, terutama untuk matakuliah program studi, khususnya pemrograman. Parameter yang disoroti pada penelitian ini adalah latar belakang keluarga, tempat tinggal, lingkungan pertemanan, sikap belajar, konsep diri, iklim kampus dan tenaga dosen. Kami berpendapat bahwa ketujuh komponen tersebut jika relevan dengan diri mahasiswa dapat memengaruhi tingkat kemampuan mahasiswa. Jaringan Syaraf Tiruan Backpropagation digunakan untuk melatih dan menguji data dari hasil kuesioner berdasarkan ketujuh komponen diatas. Dari beberapa percobaan, keluaran dan target sangat mendekati dengan tingkat akurasi mencapai 99,50% dengan nilai MSE paling kecil 10-7 atau 0,0000001.

At this time, because of the many literacy communities that have been established, we have to sort out which literacy communities are good to join, there are some literacy communities that only stand up and the system and schedule are irregular and the schedule is more dominant not according to the concept of literacy. The purpose of this research is to find or determine which community is the best place to study writing by novice writers. Using the SMART (Simple Multi Attribute Rating Technique) method, which is flexible and simple in responding to decision-making and rapid analytical responses, it is possible to determine which community is the best. With the weights and criteria used, namely Active Members (20%), Inactive Members (5%), Community Active (15%), External Community Activities (15%), Community Internal Activities (20%), Community Creativity (25 %). The alternative used is the existing community. Of the 25 alternatives used, the results obtained are the Freedom Literacy community with the highest ranking of 0.94. From this research using the SMART method, the best community has been selected to be used as a place to study writing by novice writers, namely the Feedom Literacy community.

The schedule is one of the important activities to help the teaching and learning process in schools, the schedule planning process is still done manually so there are still conflicting schedules between classes. because of the large number of classes and a lot of time ordering a certain day so that sometimes up to 3 times the revision schedule, and the implementation of learning becomes late. To overcome this, one of the appropriate ones is used so that the scheduling process can run well. One of the algorithms used for scheduling the genetic algorithm is one of the improvement algorithms that can be used in various types of problems such as scheduling, the schedule will be tested on classes that clash, which are selected randomly. random or random in each class, the test will be asked to input or fill in the crossover probability number = 0.70 and mutation probability = 0.40 and the number of generations = 1000, then executed. After that it will occur and program execution in the form of selection, crossover, and mutation that will occur in the background of the screen, so that the results of applying 17 classes and 1 laboratory room using the genetic algorithm method can be used to compile a list of lessons.

Health is a very important field in human life, there have been many studies or studies conducted in the health sector, for example nutrition problems. Nutrients are needed by humans to live healthy in order to be able to move and carry out daily activities. For the fulfillment of nutrition in toddlers is usually influenced by social and economic factors of the family. Toddlers' bodies need balanced nutrition to be able to grow and develop properly. The results of the SSGI in 2021 the stunting rate nationally decreased by 1.6% per year from 27.7% in 2019 to 24.4% in 2021. The data used in this study was 1114 toddler data. From the results of training and data testing consisting of 5 attributes, namely gender, age, weight, height, and upper arm circumference and there are 4 classes for class division, namely over nutrition, good nutrition, less nutrition and poor nutrition. And it is known that the accuracy by using 10 data samples gets an accuracy value of 80%. Thus, the system built using the Naive Bayes method is considered successful in classifying the nutritional status of children under five
