Abstract

Background: Telemarketing is an effectivemarketing strategy lately, because it allows long-distanceinteraction making it easier for marketing promotionmanagement to market their products. But sometimes withincessant phone calls to clients that are less potential to causeinconvenience, so we need predictions that produce goodprobabilities so that it can be the basis for making decisionsabout how many potential clients can be contacted whichresults in time and costs can be minimized, telephone calls canbe more effective, client stress and intrusion will be reduced.strong.Method: This study will compare the classificationperformance of Bank Marketing datasets from the UCIMachine Learning Repository using data mining with theAdaboost and Bagging ensemble approach, base algorithmusing J48 Weka, and Wrapper subset evaluation featureselection techniques and previously data balancing wasperformed on the dataset, where the expected results can beknown the best ensemble method that produces the bestperformance of both.Results: In the Bagging experiment, the best performanceof Adaboost and J48 with an accuracy rate of 86.6%, Adaboost83.5% and J48 of 85.9%Conclusion: The conclusion obtainedfrom this study that the use of data balancing and featureselection techniques can help improve classificationperformance, Bagging is the best ensemble algorithm from thisstudy, while for Adaboost is not productive for this studybecause the basic algorithm used is a strong learner whereAdaboost has Weaknesses to improve strong basic algorithm.

Abstract

Almost all universities divide their IT freshman into classes randomly or based on students score, either their score during the selection test held by the university or National Examination score. Universities often find case that a class consists of all ‘smart’ students and a class consists of all ‘lazy’ students. This thesis intends to create an application to help universities divides their Information Technology freshman into classes based on freshman competency and experience about Information Technology (IT) on the senior high school. The experiment is conducted by collecting data IT students who are not in the first semester. The data consists of their experience about IT as well as other knowledge fields and their current GPA. The results of the experiment show that from 50 data samples collected, the application correctly predicts 34 students GPA range based on respondents competency with IT and other knowledge fields during their study in senior high school.

Abstract

Harga minyak kelapa sawit bisa mengalami kenaikan, penurunan maupun tetap setiap hari karena faktor yang mempengaruhi harga minyak kelapa sawit seperti harga minyak nabati lain (minyak kedelai dan minyak canola), harga minyak mentah dunia, maupun nilai tukar riil antara kurs dolar terhadap mata uang negara produsen (rupiah, ringgit, dan canada) atau mata uang negara konsumen (rupee). Untuk itu dibutuhkan prediksi harga minyak kelapa sawit yang cukup akurat agar para investor bisa mendapatkan keuntungan sesuai perencanaan yang dibuat. tujuan dari penelitian ini yaitu untuk mengetahui perbandingan accuracy, precision, dan recall yang dihasilkan oleh algoritma Naïve Bayes, Support Vector Machine, dan K-Nearest Neighbor dalam menyelesaikan masalah prediksi harga minyak kelapa sawit dalam investasi. Berdasarkan hasil pengujian dalam penelitian yang telah dilakukan, algoritma Support Vector Machine memiliki accuracy, precision, dan recall dengan jumlah paling tinggi dibandingkan dengan algoritma Naïve Bayes dan algoritma K-Nearest Neighbor. Nilai accuracy tertinggi pada penelitian ini yaitu 82,46% dengan precision tertinggi yaitu 86% dan recall tertinggi yaitu 89,06%.

Abstract

Sulitnya menentukan klasifikasi judul skrpsi berdasarkan peminatan yang diambil oleh mahasiswa informatika unjani merupakan salah satu permasalahan penting yang dihadapi oleh pihak Jurusan. Tujuan dari penelitian ini yaitu memberikan sebuah penunjang keputusan bagi pihak Jurusan agar setiap judul skripsi yang diajukan oleh mahasiswa sesuai dengan peminatan. Berdasarkan hasil penelitian yang telah dilakukan, model yang dibangun menggunakan algoritma KNN menghasilkan tingkat akurasi yang lebih tinggi jika dibandingkan dengan model yang dibangun menggunakan algoritma VSM. Nilai akurasi tertinggi berdasarkan hasil pengujian pada penelitian ini adalah sebasar 96,85%.

Abstract

In this research, the case of intent classification for Customer Relation Management (CRM) how to handle complaints as a domain to be followed up, where datasets are extracted from the conversation on Twitter. The research objectives support three key findings to comparing the CNNs and BRNNs model to intent recognition by vectorization text: (1) Which architecture performs better (accuracy) depends on how important it is to semantically understand the whole sequence and (2) Learning rate changes performance relatively smoothly, while the optimal result iterated by change hidden size and batch size result in large fluctuations. (3) Last, how word vectorization is able to define sub-domain of the complaints by word vector classification.

Abstract

The advantage of video media in education is that it can boost students' interest in the subject matter by allowing them to watch and hear. Teachers are expected to be able to develop engaging learning materials that encourage students to participate actively in their education. This PkM activity was completed at SMPIT Annida as an activity partner. The issues that were identified were 1) The teacher's ability to self-produce learning media, particularly in making learning videos, 2) The availability of free software that could be used to produce video learning media, but never utilized by teachers, and 3) the improvement process for teaching and learning that is effective, efficient, and more engaging. The focus of this activity was on the instructors and students.
