Pada proses klasifikasi buah tomat dengan cara manual yaitu dengan menggunakan mata manusia merupakan hal yang sangat sulit dilakukan. Hal ini dibuktikan dengan tidak konsisten serta bersifat subyektif sehingga menyebabkan tingkat akurasi yang rendah. Oleh karena itu, untuk meningkatkan tingkat akurasi serta mengurangi sifat subyektifitas mata manusia, maka penelitian ini mengusulkan sebuah algoritma yang dapat digunakan untukk mengklasifikasi tingkat kematangan buah tomat yaitu dengan K-Nearest Neighbor berdasarkan kepada warna kulit yang ada pada buah tersebut. Nilai k yang digunakan pada penenlitian ini yaitu 1, 3, 5, 7, dan 9 untuk menguji coba pencarian jarak Euclidean distance pada citra dengan ukuran 512x512 piksel. Penelitian yang dilakukan membuktikan bahwa dengan jarak Euclidean k=3 memiliki nilai prosentase 92%. Berdasarkan tingkat akurasi yang dimiliki, fitur warna k=3 menunjukkan nilai k terbaik pada klasifikasi tingkat kematangan buah tomat.

The research instrument is used to collect data or measure the object of a study. The purpose of this study was to determine which instruments were declared valid and reliable and to find out the variables with the highest validity and reliability values. Validity testing is carried out to determine the effectiveness of an instrument, while reliability testing is carried out to show the level of reliability of the indicators used. Testing the validity and reliability using software SmartPLS version 3.3.2 with a measurement scale that is Likert scale. Validity testing is done by looking at the average variance extracted (AVE) value and the comparison of the latent variable correlations values, while reliability testing is done by looking at the composite reliability value. The population in this study were active students at the State Islamic University (UIN) Raden Fatah Palembang, totaling 19,260 students with the determination of the sample using the Slovin formula with a level of significance = 5%. Data collection in this study was carried out by distributing online questionnaires. The questionnaire was made based on indicators on the model used, where the models used were UTAUT 2 and EUCS. The UTAUT 2 model can be used to measure the level of user acceptance of the system consisting of the variables of performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivation, perceived value, habit, and behavioral intention. Furthermore, the EUCS model is used to measure the level of user satisfaction which consists of content, accuracy, format, ease of use, timeliness, and user satisfaction variables. The results of the validity and reliability testing state that all indicators are valid and reliable with an AVE value > 0.50 in the validity test and the composite reliability value > 0.70 in the reliability test. The validity test with the highest value is found in the ease of use variable with an AVE value of 0.826 and reliability testing with the highest value is found in the performance expectancy variable with a composite reliability value of 0.924. With this research, it is expected to obtain variables in the model to evaluate user acceptance and satisfaction with academic information systems

This study aims to produce valid and practical PISA-based numerical problems in the context of the pandemic period and to find out the role of the questions in the form of potential effects on the mathematical literacy skills of secondary school students. This research uses developmental research design, which has 2 stages, namely preliminary and formative evaluation (self evaluation, expert review, one-to-one and small group validation, and field test). The participants in this study were students in Grade 8 who were under the age of 15 and different levels of skills. Data analysis was done descriptively by conducting observations, tests, interviews, and document analysis. The research was conducted face-to-face and via Zoom and WhatsApp Group (WAG) to produce valid and practical PISA-like arithmetic questions. Based on the students' responses, it can be stated that the questions presented are in the practical category because they can be completed quickly by students, they can be understood well by students, and they have the potential effect on students' mathematical literacy skills. In addition, there is a diversity of answers between one students and another according to the level of difficulty that is appropriate for Grade 8 students. This proves that a PISA-like numeration problem in the context of the religious day during a pandemic can help improve students' mathematical literacy.

This research belongs to the type of development research, which consists of the main stages, including preliminary design and formative evaluation. This study aims to obtain valid and practical PISA-type development questions consisting of initial design, self-evaluation, expert review, one-to-one, and small group. The emergence of this research is due to the low mathematical literacy of students in Indonesia. This study took a particular research subject for grade IX junior high school students in Palembang City.

Problem (JSSP) is a problem to determine the sequence of operations carried out on existing machines with the aim of minimizing the total processing time required. The development of optimization methods to achieve solutions to machine operation sequence problems has encouraged the emergence of many new solution methods. This research wants to compare two solution methods using Ant Colony Optimization (ACO) and Genetic Algorithms. The two methods are compared to find out which optimization is best used to solve the JSSP problem. The results of this research show that the ACO algorithm is better with mean squared error of 72.99%, compared to the Genetic Algorithm with mean squared error of 11.71%.
