Abstract

This paper proposes two strategies for handling conflict schedule of two meetings which invite the same member of personnel at the same time through host-to-host negotiation scheme. The strategy is to let the member attend the other meeting under the condition that the group decision regarding the schedule is not changed and meeting quorum is fulfilled, namely release strategy. Other strategy is to substitute the absent personnel in order to keep the number of attendees above the quorum, namely substitute strategy. This paper adapts a mechanism design approach, namely Clarke Tax Mechanism, to satisfy incentive compatibility and individual rationality principal in meeting scheduling. By using a release strategy and substitute strategy, colliding meetings can still be held according to the schedule without the need for rescheduling. This paper shows the simulation result of using the strategies within some scenarios. It demonstrates that the number of meeting failures can be reduced with negotiation.

Abstract

This paper presents a different scheme of meeting scheduling negotiation among a large number of personnel in a heterogeneous community. This scheme, named Host-to-Host Negotiation, attempts to produce a stable schedule under uncertain personnel preferences. By collecting information from hosts’ inter organizational meeting, this study intends to guarantee personnel availability. As a consequence, personnel’s and meeting’s profile in this scheme are stored in a centralized manner. This study considers personnel preferences by adapting the Clarke Tax Mechanism, which is categorized as a non manipulated mechanism design. Finally, this paper introduces negotiation strategies based on the conflict handling mode. A host-to-host scheme can give notification if any conflict exist and lead to negotiation process with acceptable disclosed information. Nevertheless, a complete negotiation process will be more elaborated in the future works.

Abstract

Diabetes mellitus is a global health problem that can affect anyone, from children, adolescents, to adults. Therefore, diabetes is one of the non-communicable diseases that has become a serious threat to global health. Since 1980, the number of diabetics worldwide has nearly doubled from 4.7% to 8.5% of the total population. The International Diabetes Federation (IDF) even estimates that the number of diabetes sufferers worldwide will reach 700 million people by 2045. In response to this condition, this study predicts diabetes diagnosis using machine learning algorithms, artificial neural network. However, there is a major problem with this algorithm, namely in determining the correct architecture. This problem can be viewed as an optimization problem, where many architectural possibilities that can occur. Therefore, to search for the right architecture to increase the accuracy of the predictions, there will be stages to use the evolution algorithm. Because this algorithm is very suitable to be applied in an optimization case. This study implements Evolving Artificial Neural Network (EANN) algorithm to predict the patient's diagnosis. It is with the hope that this study can produce higher accuracy in predicting patient diagnosis in diabetes. The data set used was Pima Indian Diabetes from the UCI Machine Learning Repository. Based on the experiments that have been carried out, the best model produced has an accuracy of 83.55%. This means that the algorithm used is quite successful in predicting diabetes diagnosis.

Abstract

Menghafal Alquran bukanlah suatu perkara yang mudah, akan tetapi jauh lebih sulit menjaga dan mempertahankan hafalan yang sudah ada. Proses menghafal Alquran selain dilakukan dengan tatap muka langsung dengan guru tahfidz, perlu juga dilakukan secara mandiri. Salah satu cara alternatif yang dapat membantu proses menghafal secara mandiri adalah dengan menggunakan perangkat lunak berbasis mobile. Penelitian ini bertujuan untuk mengembangkan sebuah game edukasi sebagai cara alternatif yang dapat membantu menghafal dan mengulang kembali ayat yang dihafalkan menjadi menyenangkan. Rancangan perangkat lunak yang akan dibuat adalah dengan mengombinasikan unsur game dan metode hafalan yang menggunakan kata awal ayat Alquran. Proses menghafal ayat Alquran dilakukan dengan cara menebak kata awal ayat Alquran yang dimunculkan secara acak pada game beserta pencocokan secara otomatis menggunakan kata kunci. Kata awal ayat Alquran dibangkitkan menggunakan algoritma fisher yates sebagai pembangkit bilangan acak. Fisher yates diterapkan pada pengacakan soal dan posisi jawaban. Hal ini dilakukan agar soal dan jawaban memiliki urutan yang berbeda dengan sebelumnya. Berdasarkan hasil pengujian dapat disimpulkan bahwa aplikasi mobile Murajaah telah memenuhi fitur-fitur dalam penerapan metode menghafal Alquran serta dapat membantu pengguna dalam menghafal Alquran.

Abstract

In facing the challenges of the digital era, education in Indonesia must innovate through the integration of technology to produce a superior workforce. Traditional teacher-centered teaching methods have become an obstacle to developing students' logical thinking skills in problem-solving and conclusion-drawing. This research aims to develop and test the effectiveness of website-based interactive multimedia using the discovery learning model on the Entity Relationship Diagram (ERD) topic to enhance students' logical thinking skills. The media development employed the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), with the interactive multimedia flow designed according to the stages of discovery learning. Effectiveness was measured using a one-group pretest-posttest design with vocational high school students in West Bandung, while the feasibility of the material and media was validated by experts. The improvement in logical thinking skills was measured using the N-gain test. The results showed that the developed interactive multimedia was declared highly feasible by material and media experts. The effectiveness test indicated an improvement in students' logical thinking skills, with an N-gain score in the medium category. However, a detailed breakdown of the improvement per aspect revealed that argumentation skills were moderate, while thought coherence and conclusion-drawing skills remained low. These difficulties were attributed to a lack of student initiative and motivation in discussion and summarizing the material. It is concluded that this interactive multimedia is feasible and effective as an alternative learning medium for training students' logical thinking skills, although further optimization is needed to improve thought coherence and conclusion-drawing abilities.
