Abstract

This research is motivated by the owner of a wholesale pen trading business, so far CV. SARWODADI is still doing promotions and sales manually, so the range of promotions and sales is still limited and cannot be extended to several areas which causes the products produced to be less well known by the wider community. Troubleshooting solutions in CV. SARWODADI, namely by implementing a website-based sales application, so that it is expected to increase sales and marketing of CV. SARWODADI. The goal achieved is as a promotional media on the CV. SARWODADI and make it easier for consumers to see and buy products without having to go to the store. The research method used is the interview method, namely by asking questions directly to the owner of the UD. Irma Jaya Pen about how the flow of sales transactions, purchases, availability of goods, and the reporting process in CV. SARWODADI. Library Method by reading books and understanding materials related to Web-Based Wholesale Sales Applications on CV. SARWODADI is to learn the manual system that is running on CV. the SARWODADI. The result to be achieved is that it is hoped that the Web-Based Wholesale Sales Application can overcome the problems that exist in the old system so that it is able to meet all system needs.

Abstract

The image problem lies in the amount of storage space required, to save memory as little as possible image compression is required. The image compression technique is a technique used to represent an image by reducing the quality of the original image but still retaining the information inside. This study compares the best compression method between Coiflets, Haar wavelets, and SVD with JPG image material. The comparison process has done by calculating the compression ratio (CR), Space Saving (SS), Mean Square Error (MSE), Root Mean Square Error (RMSE), and Peak Signal to Noise Ratio (PSNR). The results obtained prove that the SVD method has the highest compression ratio of 3.25 while in the case of Space Saving (SS) the Coiflets method gives the best performance with a value of 73. Measurement in terms of MSE and RMSE is the best for the Coiflets method because it has an average value. -The smallest average among all methods is 0.02395 and 0.111383. provides the best performance in maintaining compression quality. The best PSNR based image quality assessment is the Coiflets method with the highest PSNR average of 63.02 dB. Overall, the Coiflets, Haar wavelet, and SVD compression methods used for JPG images can reduce file size and preserve image information and quality.

Abstract

Terdapat beberapa kendala atau gangguan dalam jaringan wireless, salah satunya adalah obstacle. Obstacle mengakibatkan sinyal teredam dan kualitas jaringan tidak optimal. Akses point to point yang berjarak lebih dari 5km memiliki tantangan tersendiri, karena obstacle freshnel zone yang berupa lengkung bumi harus diperhatikan. Untuk mengatasi kendala obstacle fresnel zone tersebut biasanya peletakan radio acces point dan radio station dipasang setinggi mungkin agar terbebas dari obstacle fresnel zone. Penelitian ini mempelajari tentang pengaruh obstacle fresnel zone terhadap kualitas sambungan point to point, hingga diperoleh informasi berupa prosentase gangguan obstacle fresenl zone yang masih bisa ditoleransi. Informasi tersebut diharapkan dapat memberikan masukan dalam pertimbangan tinggi tower / peletakan tinggi radio dari permukaan tanah, sehingga kemungkinan terjadinya peristiwa yang memiliki resiko sangat besar seperti robohnya tower dan tersambar petir dapat diminimalisir.
