Abstract

Nutritional needs are very necessary for pregnant women. Good nutrition is balanced nutrition and according to needs. If the needs of pregnant women are not suitable can experience Chronic Energy Deficiency with these problems, a system is needed to fulfill the nutrition of pregnant women who can provide solutions in the form of food ingredients in accordance with the method of Hybrid Genetic Algorithms and Annealing Simulation. In the process of solving this problem at Simulated Annealing or Genetic Algorithm. This hybrid process is in a crossover process using a single intersection, mutation insertion for the mutation process and the use of elits in the selection and simulation of Annealing. The previous test results obtained parameters with the Hybrid GA and SA method obtaining the best parameter value which is equal to 100 (population size) fitness which obtained an average of 0.06268, the value of 105 (generation) obtained by average fitness0. 06823, i 4 with a fitness value of 0.6, the average is 0.06792, and the average temperature with a value of 1 and apha is 0.5 obtained by the best fitness with an average of 0.06800 along with 0.08876. The hybridization suitability of GA and SA reached 0.08804 higher than the average GA suitability value of 0.05519 and SA suitability which was 0.04382 with a specified time of 1 minute and the requirements generated from the system were insufficient for the nutritional needs of the pregnant women.

Abstract

Human Papilloma Virus is a virus that causes warts in humans. There are so many types of treatment for this virus, the most common types of treatment are immunotherapy and cryotherapy. The symptoms that appear in the patient are almost similar, so that proper handling is needed. Based on this, the Extreme Learning Machine method is used to classify the types of treatment of Human Papilloma Virus. The symptom parameters used were 6 parameters and the classes used were immunotherapy and cryotherapy. In this research, the initial weight of the Extreme Learning Machine was optimized by Genetic Algorithm and then the weight was used by the Extreme Learning Machine method for the classification process of the types of treatment of the Human Papilloma Virus. The amount of data used is 118 data with the data ratio for the training process and the test process is 80:20. The Extreme Learning Machine parameters used are 10 hidden neurons and binary sigmoid activation functions. The test results obtained the best classification accuracy level of 100% for both treatment, cryotherapy and immunotherapy from 3 of 10 testing with an average computation time of 350,3 seconds using the initial weight which was optimized by the Genetic Algorithm with the best parameter population size of 70, the number generations of 160, the crossover rate of 0.9 and the mutation rate of 0.1.

Abstract

Pregnant women need to increase their knowledge to find out how big the level of risk of getting a disease, especially because of the vulnerability of pregnant women. Classification of the level of disease risk in pregnant women is expected to assist users in finding the right solution to overcome it. The classification method used to determine the level of disease risk for pregnant women uses Modified K-Nearest Neighbor (MKNN). Classification of disease risk levels in pregnant women using the Modified K-Nearest Neighbor (MKNN) method can make it easier to detect disease based on existing factors. The Modified K-Nearest Neighbor (MKNN) method is implemented on the expert system inference engine so that conclusions can be drawn based on existing knowledge. The results of the accuracy of the system obtained after testing is 85% which indicates that the Modified K¬-Nearest Neighbor (MKNN) method is suitable for studying the level of disease risk in pregnant women.

Abstract

Penjadwalan perkuliahan di universitas adalah kegitan rutin yang membutuhkan waktu relatif lama untuk menyelesaikannya jika dikerjakan secara manual. Waktu yang dibutuhkan akan semakin besar ketika semakin banyak constraint yang dipertimbangkan. Mekanisme penanganannya akan berbeda di tiap universitas karena mungkin mereka mempunyai constraint yang unik. Dalam paper ini dipaparkan berbagai algoritma penanganan untuk tiap jenis constraint dalam persoalan penjadwalan perkuliahan. Algoritma penjadwalan perkuliahan otomatis yang digunakan dalam penjadwalan otomatispenelitian ini adalah sequential search yang bekerja dengan cara mencari slot waktu yang masih belum dipergunakan untuk ditempati oleh kelas perkuliahan . Bila slot waktu telah dipergunakan maka sistem akan mencari slot waktu yang lain secara berurutan. Uji coba dilakukan di program studi Teknik Informatika UIN Malang pada semester Ganjil tahun akademik 2021/2022. Hasilnya menunjukkan bahwa dengan 10 constraint, sistem yang dibangun dapat menjadwalkan 190 kelas perkuliahan secara otomatis dan 21 kelas perkuliahan dijadwalkan secara interaktif. Dengan sistem yang diajukan maka seluruh kelas perkuliahan sebanyak 211 dapat terjadwal meskipun ada pelanggaran soft constraint oleh 17 kelas perkuliahan.

Abstract

A Regional Hospital in East Java has implemented a Hospital Management Information System, namely SIMRS, in their data management system but has experienced problems in the form of slow system response when accessed by many users, was experienced in the last years when the system had been running for four years since 2016. The system’s slow response causes hospital services to be disrupted and also the quality of service to decline. So, an analysis to the existing database system is carried out, which includes an analysis of the system‘s database performance. Since many SIMRS use database servers on their data processing, then their applications will be based on executing queries and stored procedures (most of the queries are stored in stored procedures). So that, analysis of those queries will be carried out. The optimization process will include analyzing and mapping the database’s queries, profiling, and analyzing the Actual Execution Plan. By doing so, it is known which parts of the query are causing a decrease in performance and time system response. Based on the analysis results, recommendations are given for improving and rewriting several stored procedures and query statements, and the system response time is getting better.

Abstract

Breast cancer may cause a death due to the late diagnosis. A cheap and accurate tool for early detection of this disease is essential to prevent fatal incidence. In general, the cheap and less invasive method to diagnose the disease could be done by biopsy using fine needle aspirates from breast tissue. However, rapid and accurate identification of the cancer cell pattern from the cell biopsy is still challenging task. This diagnostic tool can be developed using machine learning as a classification problem. The performance of the classifier depends on the interrelationship between sample sizes, some features, and classifier complexity. Thus, the removal of some irrelevant features may increase classification accuracy. In this study, a new hybrid feature selection fast correlation based feature (FCBF) and information gain (IG) was used to select features on identifying breast cancer using AIRS algorithm. The results of 10 times the crossing (CF) of our validation on various AIRS seeds indicate that the proposed method can achieve the best performance with accuracy =0.9797 and AUC=0.9777 at k=6 and seed=50.

Abstract

The Pap smear is a screening method for early cervical cancer diagnosis. The selection of the right optimizer in the convolutional neural network (CNN) model is key to the success of the CNN in image classification, including the classification of cervical cancer Pap smear images. In this study, stochastic gradient descent (SGD), root mean square propagation (RMSprop), Adam, AdaGrad, AdaDelta, Adamax, and Nadam optimizers were used to classify cervical cancer Pap smear images from the SipakMed dataset. Resnet-18, Resnet-34, and VGG-16 are the CNN architectures used in this study, and each architecture uses a transfer-learning model. Based on the test results, we conclude that the transfer learning model performs better on all CNNs and optimization techniques and that in the transfer learning model, the optimization has little influence on the training of the model. Adamax, with accuracy values of 72.8% and 66.8%, had the best accuracy for the VGG-16 and Resnet-18 architectures, respectively. Resnet-34 had 54.0%. This is 0.034% lower than Nadam. Overall, Adamax is a suitable optimizer for CNN in cervical cancer classification on Resnet-18, Resnet-34, and VGG-16 architectures. This study provides new insights into the configuration of CNN models for Pap smear image analysis.
