This study attemp to build Smart Digital Library to be used by the wider community wherever they are. The system is built in the form of Smart Digital Library portal which uses semantic similarity method (Semantic Similarity) to search journals, articles or books by title or author name. This method is also used to determine the recommended books to be read by visitors of Smart Digital Library based on testimony from a previous reader automatically. Steps being taken in the development of Smart Digital Library system is the analysis phase, design phase, testing and implementation phase. At this stage of the analysis using WebQual for the preparation of the instruments to be distributed to the respondents and the data obtained from the respondents will be processed using Quality Function Deployment. In the analysis phase has the purpose of identifying consumer needs and technical requirements. The analysis was performed to a digital library on the web digital library Gunadarma University, Bogor Institute of Agriculture, University of Indonesia, etc. The questionnaire was distributed to 200 respondents. The research methodology begins with the collection of user requirements and analyse it using QFD. Application design is funded by the government through a program of Featured Universities Research by the Directorate General of Higher Education (DIKTI). Conclusions from this research are identified which include the Consumer Requirements of digital library application. The elements of the consumers requirements consists of 13 elements and 25 elements of Engineering Characteristics digital library requirements. Therefore the design of digital library applications that will be built, is designed according to the findings by eliminating features that are not needed by restaurant based on QFD House of Quality.

Determination of sales targets made by palm shell export companies is often not appropriate and effect the amount of inventory of palm shells sold based on weight which will be reduced if stored too long. Implementation of Least Square method for forecasting the sale of palm shells on web platforms aims to help the company to determine sales targets more accurately. By using this application, companies can forecast for the sale of palm shells for the next month in one year starting from one month after the actual sales period that has been entered. Data testing using Mean Absolute Error (MAPE) shows the error generated is 5.935%, Black Box testing results reach 100%, and User Acceptance Testing shows users agree the application in accordance with the requirements and forecasting results is clearly displayed.

IPB University berdiri sejak tahun 1963 sebagai salah satu perguruan tinggi ternama di Bogor. Pandemi membuat civitas akademik IPB University untuk melakukan kegiatan belajar mengajar jarak jauh. Namun, berjalannya Learning Management System (LMS) belum cukup untuk melayani ribuan pengguna tanpa kesalahan. High-availability menjadi desain lingkungan produksi esensial untuk meminimalisir kegagalan karena ada sistem lain yang dapat menggantikan sehingga proses produksi tidak terganggu. Untuk mewujudkan konsep high-availability pada LMS, diperlukan perencanaan skema sistem server yang matang. Penelitian ini mengimplementasikan konsep high-availability pada server LMS terdistribusi dengan menggunakan load balancing, web clustering, dan juga database clustering. Implementasi menggunakan serangkaian server basis data, server web, server NFS, server load balancing web, dan juga server load balancing basis data. Sistem terimplementasi telah diuji berdasarkan kebutuhan fungsional yang sesuai. Pengujian yang dilakukan ditinjau dari pengamatan terhadap waktu respon dan juga performa LMS. Hasil pengujian menunjukkan bahwa LMS telah mengaplikasikan konsep high-availability ketika terjadi suatu kesalahan pada salah satu server web. Pengujian juga menunjukkan bahwa kinerja server web telah seimbang menggunakan leastconnected load balancer. Ketika salah satu server web tidak dapat diakses, maka server web yang lain mengambil request client sehingga sistem tetap dapat berjalan.
