Abstract

The Ministry of Education and Culture (Kemendikbud) issued Circular Letter Number 15 of 2020 concerning Guidelines for Organizing Learning from Home in an Emergency for the Spread of Covid-19. This causes the learning process that should be done face-to-face, being changed to online. Students must study from home and carry out the online thesis guidance process. Some of the difficulties experienced by students during direct mentoring, namely the difficulty of meeting lecturers who are busy teaching or doing assignments from institutions, besides that students who come from outside the city have to go back and forth just to meet the supervisor.. One of the ways to solve this problem is by applying technology.   Currently there is web technology that can be used to easily develop applications, namely the concept of a framework approach. With the existence of an online-based application which is the role of current technological developments, it will make the thesis guidance process carried out by lecturers and students more flexible. Students are able to carry out the guidance process anywhere and anytime.

Abstract

The diversity of the content of a web page can have a negative impact if used by the wrong user. Almost a half of internet users are children. Therefore, it is important to classify web pages to find out which pages are worthy of being seen by children and that are not feasible. One method that can be used is the Support Vector Machine (SVM) algorithm. SVM is a binary classification whose working principle is to find the best hyperplane to separate the two classes. To obtain better classification accuracy, the SVM is combined with the Latent Semantic Analysis (LSA) algorithm. The data used in this study were taken from the DMOZ web data which has been classified into two categories. The data is then entered into the pre-processing stage for further feature extraction using LSA. The LSA algorithm is used to find out the semantic similarities of words and text contained in web pages. The results of feature extraction are then classified using SVM with RBF kernel. Based on the testing result, we obtain a classification accuracy of 64%.

Abstract

aset wakaf berupa tanah yang tersebar di Indonesia terbilang cukup besar, sehingga aset wakaf yang besar ini perlu dikelola dengan baik agar tidak menimbulkan banyak permasalahan yang pada akhirnya tanah wakaf tidak sesuai dengan tujuannya dan tidak dapat digunakan untuk kepentingan umat. Instrument pengamanan aset wakaf telah memenuhi, namun masih banyak muncul persoalan mengenai aset wakaf seperti menguapnya bondo wakaf, sengketa, alih fungsi, dll, sehingga dalam hal ini menunjukan bahwa banyak persoalan terkait pengelolaan aset wakaf yang harus dipecahkan. potensi wakaf sangat besar, bahkan diperkirakan potensi tanah wakaf di indonesia mencapai lima kali luas singapura, namun saat ini belum dikelola secara profesional dan lebih produktif. Penggunaan tanah wakaf di indonesia masih identik dengan masjid dan makam, padahal wakaf dapat juga dikelola menjadi aset-aset ekonomi yang menghasilkan keuntungan sehingga hasil dari wakaf produktif tersebut dapat digunakan untuk kepentingan umat. K-Nearest Neighbors (KNN) merupakan algoritma klasifikasi yang didasarkan pada analogi yaitu membandingkan data uji dengan data latih yang berada dekat dengan dan memiliki kemiripan dengan data uji tersebut, dalam penelitian ini KNN digunakan sebagai metode untuk klasifikasi aset wakaf guna mengidentifikasi aset wakaf tersebut berpotensi produtif atau tidak produktif. Penelitian dilakukan dengan menggunakan 57 data aset wakaf yang diperoleh dengan membagi menjadi 45 data untuk training dan 12 untuk testing. Hasil pengujian yang telah dilakukan membuktikan metode KNN ini memiliki akurasi yang baik untuk klasifikasi aset wakaf yaitu mencapai 93% pada data training dan 83% pada data testing.

Abstract

CV. YustiKarya as a construction company realizes that the ability to manage project finance is one of the important requirements for smooth project management. CV. YustiKarya often has to manage several projects simultaneously with remote locations. This condition made it difficult for financial staff in the office to manage project financial allocations and also made it difficult for project managers in the field and had to report the status of project expenditures to the office. This difficulty drives CV. YustiKarya is to improve the project's financial management system which originally used a spread sheet to become a web-based information system. Web-based information systems will be developed using object-oriented methods. The object-oriented system development method was chosen because of its modular development capabilities and adapts to system requirements. The information system that is produced is able to create a construction project management system starting from employer entry, contract entry, billing entry, printing proof of receipt, printing proof of expenditure, and generating project income and expenditure reports online. Web-based information systems will automate the financial status of projects whose locations are scattered. This system also makes it easy for directors to be aware of current project developments.
