Terlebih dengan semakin berkembangnya mutasi atau varian virus SAR-CoV-2, tentu kegiatan pembelajaran konvensional dengan hadir di kelas menjadi belum jelas kapan dilaksanakan. Itu sebabnya pihak pendidik memerlukan sentuhan kreatifitas, agar proses belajar mengajar dari rumah tetap menyenangkan peserta didik. Maka rumusan masalah dalam kegiatan abdimas ini adalah bagaimanakah menumbuhkan kreatifitas elearning melalui pembelajaran media animasi interaktif berbasis edufun (education & fun) guna meningkatkan semangat pembelajaran di era pandemic Covid 19 ini? Tujuannya guru bisa meningkatkan ketrampilan pembelajaran melalui pembelajaran media animasi interaktif berbasis edufun (education & fun), sementara siswa-siswi tetap bisa mengikuti proses transfer of knowledge yang kreatif pada masa pandemic. Metode kegiatan ini terbagi atas dua kegiatan. Pertama penyampaian materi dasar teknik-tenik pembelajaran inovatif dan kedua praktik langsung (simulasi) pembuatan animasi sederhana yang diikuti oleh guru pembina dan siswa-siswi kelas VII SMPN 24 Surabaya. Hasil pelatihan ini guru memperoleh pengetahuan dan ketrampilan membuat animasi sederhana. Siswa yang mengikuti kegiatan memperoleh pengetahuan baru dan ketrampilan teknis pembuatan animasi model pembelajaran yang kreatif dengan topik lingkungan, teknologi, pendidikan, persahabatan, transportasi dan arsitektur/konstruksi.

Teeth has a really important role for human life and it is certainly very dangerous if our teeth are having problems, given the fact that teeth disease can cause death. But with the minimum knowledge and information it is impossible to keep our teeth healthy, so an expert is needed to solve this problem about teeth disease and how to keep the teeth healthy. From the fact above, this last project could help us to diagnose the teeth disease and anticipate the risk of teeth disease by designing and implementing this application. This application made web-based (PHP) by using Dreamweaver and XAMPP as the MYSQL database server. This expert system will give a couple of questions to the patient. After all of the questions answered then the diagnosis with the solution will be shown to the patient that will help the patient to anticipate the teeth disease.

Most of universities implement intelligent information system to support in achieving their vision and mission. One of the features of Intelligent Information System is student performance prediction. By implementing data mining method, this feature could accurately predict the student' grade for their enrolled subjects. Moreover, it can identify students that are at risk in failing a course and allow top educational management to take corrective actions. In this research, linear multi regression model was proposed to build model for every student. Based on the testing result on large set of students, courses, and activities shows that these models are capable of improving the performance prediction accuracy by over 15%.

Toko Niaga juga menjual barang-barang bangunan seperti paku, pipa, selang, cat tembok, dan lain-lain.Dalam melakukan proses bisnisnya, pencatatan akuntansi masih belum secara menyeluruh. Proses yang masih manual tersebut memiliki banyak risiko. Salah satu risiko yang sering sekali terjadi adalah risiko human error. Untuk itu proses akuntansi ini harus dikomputerisasi dengan Sistem Informasi Akuntansi.Oleh karena itu, dengan mengimplementasikan Sistem Informasi Akuntansi, maka proses pencatatan akuntansi dalam Toko ini akan lebih terstruktur dan mengurangi human error yang dapat terjadi. Berdasarkan latar belakang permasalahan itu, penulis merancang sistem informasi akuntansi yang dapat melakukan penjurnalan secara otomatis dan menghitung laba rugi dengan lebih tepat dan mudah. Proses pembuatannya menggunakan PHP dan Mysql. Secara keseluruhan aplikasi ini telah sesuai dengan kebutuhan toko.Aplikasi ini dapat membantu owner dalam mengetahui keadaan keuangan toko melalui laporanlaporan yang dihasilkan oleh aplikasi ini.Hasil yang diperoleh dari aplikasi yang telah dibuat antara lainlaporan laba rugi,laporan perubahan modal, laporan neraca, laporan penjualan, laporan pembelian, laporan hutang, laporan piutang, laporan kas masuk, laporan kas keluar, dan buku besar.

Most of universities implement intelligent information system (IIS) to support in achieving their vision and mission. One of the features of IIS is student performance prediction. By implementing data mining model in IIS, this feature could precisely predict the student' grade for their enrolled subjects. Moreover, it can recognize at-risk students and allow top educational management to take educative interventions in order to succeed academically. In this research, multi-regression model was proposed to build model for every student. In our model, learning management system (LMS) activity logs were computed. Based on the testing result on big students datasets, courses, and activities indicates that these models could improve the accuracy of prediction model by over 15%.

Genetic programming have proven to be a good technique for solving data set classification problems but at high computational cost. The objectives of this research is to accelerate the execution of the classification algorithms by proposing a general model of execution in GPU of the adjustment function of the individuals of the population. The computation times of each of the phases of the evolutionary process and the operation of the model of parallel programming in GPU were studied. Genetic programming is interesting to parallelize from the perspective of evolving a population of individuals in parallel.

The selection process in the area of awarding scholarships often uses a manual process which examines the candidate's qualifications according to that specified by the scholarship scheme. The main objective of this research is to reduce the inefficiencies within the process and improving the quality of the final decision by minimizing the degree of personal preference. In this research, Analytical Hierarchy Process (AHP) has been implemented in awardees short listing system at Petra Christian University. Based on these needs, required a system that can provide considerations determine the decision of the scholarship recipients. Such systems provide objective results based on the terms and conditions have been determined by comparing the value of each scholarship recipients. So the result is in accordance with input provided by potential recipients. Based on the questionnaire result, this application meets with end user requirements, 70% of the respondents said this application improve the efficiency of decision making process in terms of multi criteria decision making ability.

The absence of efficient wastewater management has caused serious environmental problems and cost issues. Therefore, in this paper IoT-based data logger and pH controller is proposed to reduce the inefficiency. IoT is a concept whereby objects around us can interact and exchange information with each other without human intermediaries through the Internet. One of the implementation of IoT is to monitor the level of liquid acidity through smartphones. It needs additional tools such as sensors, microcontrollers, and other devices that are then connected to the internet. Android-based mobile phone is used to interact with sensors, microcontroller, and other tools through the internet wherever the user is. From the testing, there is a successful communication between the components of the device, sensors, and Android devices. It is possible to adjust the acidity of the liquid automatically by activating the pump in accordance with the results of the pH reading
