Berkembangnya ilmu pengetahuan dan teknologi informasi membuat manusia mencari cara yang cepat untuk memudahkan kegiatan usaha. Salah satu caranya adalah menggunakan teknologi informasi berupa website. Kelompok Tani Bibit Durian Maju Makmur adalah sebuah kelompok tani yang bergerak dibidang tanaman dan berada di desa Alasmalang Kabupaten Banyumas. Namun penjualan dan pemasaran bibit durian pada Kelompok Tani Maju Makmur belum memanfaatkan adanya website ataupun penggunaan e-commerce karena keterbatasan pengetahuan tentang internet. Para petani hanya menggunakan handphone untuk sarana penjualan maupun pemasaran. Dengan pembuatan website untuk Kelompok Tani Maju Makmur dapat mengatasi masalah transaksi penjualan dan pemasaran bibit durian. Perancangan sistem informasi berbasis website ini menggunakan Dreamweaver CS6, PHP, HTML, dan XAMPP. Metode yang digunakan dalam pengembangan sistem ini yaitu dengan model waterfall. Untuk pengujian unit menggunakan Black Box Testing. Dengan keberadaan website dapat membantu konsumen atau pelanggan dalam mengakses informasi kapan dan dimana saja, serta bisa menjadi sarana promosi untuk memperluas jangkauan pemasaran produk dan menambah penghasilan.

In the current era of globalization, information technology is advancing rapidly. As for computers and smartphones which are sophisticated equipment that is indeed made to facilitate a work carried out by humans. Home Industry of Sugar Red Powder Dalban Permana currently requires an information system that supports and provides satisfactory services for customers. At present the system used in the Home Industry of Red Sugar Powder Dalban Permana is still manual, both in recording customer purchases, the number of orders for items to be purchased, and the storage of data related to the sales process. So as to allow errors in the recording process. This information system development is the best solution to solve existing problems, and with this web-based information system can be achieved an effective and efficient activity in supporting activities in this home industry.Abstrak -Di era globalisasi saat ini, teknologi informasi melaju dengan pesat.

Clustering is a method of dividing datasets into several groups that have similarity or the same characteristics. High-dimensional Datasets will influence the effectiveness of the grouping process. This study compares two dimension reduction algorithms, namely Principal Component Analysis (PCA) and Singular Value Decomposition (SVD) using K-Means clustering method to find out the best algorithm with the smallest Bouldin Davies Index evaluation. The dataset of this study involved public data from UCIMachine Learning which contains the number of weekly sales of a product. Data processing is performed by comparing the number of clusters from 3 to 10 and the dimension reduction from 2 to 10. From the data processing the RapidMiner tools, application with dimension reduction can provide better results than without dimension reduction. In particular, the PCA algorithm shows better results than the SVD, with which the best number of clusters is 5, and the number of dimensional reductions is 3 with a Bouldin Index of 0.376.

Computer technology is one of the technological advances that has developed rapidly at this time. Where its function makes it easier for humans to do work and makes it easier to get information. Internet technology is one of the supporting factors for users to be able for access all information without going to the destination. The library information system is a system that involves humans and technology. Along with the development of electronic or digital library technology, it's starting to appear in the midst of conventional libraries, although it is still very limited. The habit of reading books in the library room will slowly be replaced by the habit of reading books online and there's no need to come to the conventional library. Regarding the habit of reading books, one of the factors causing low literacy in Indonesian society is the lack of reading materials and improper literacy practices. One way to improve literacy is the development of interest in reading and reading habits. The development of a website-based library electronic information system (E-Peru) can be a solution to this problem. To the design application using Visual Studio Code with the PHP programming language and the database using MySQL. The method for the development of this system is Waterfall model. With E-Peru it can make it easier for users to get information and knowledge without going to a conventional library. Can also increase interest in reading and educate the public.
