Abstract

Garbage is the residual material resulting from a production process, both industry and households. Based on Brebes district's statistical data, the Paguyangan sub-district is in fourth place with an average of 249.62 m3 of garbage per day. Paguyangan is one of the villages in the Paguyangan sub-district. Paguyangan has a garbage problem where people still have the habit of throwing garbage in the river and yards around the house. Based on this, the Paguyangan Village Hall plans to build a garbage bank to overcome the problem. A garbage bank managed activities such as recording savings transactions. This study conducted a web-based design of the Garbage Bank Information System (SIBS). SIBS is an information system used to help process garbage transactions at a garbage bank. The purpose of this SIBS is to facilitate officers and customers in processing services at the garbage bank. The methodology used in system development is the Waterfall method. SIBS development uses PHP as a programming language and MySql as the DBMS. The result of this research is a garbage bank information system. SIBS can be used in the management of garbage management transactions. Testing the system using Blackbox Testing and MOS. SIBS is easy to operate from the test results obtained.

Abstract

One of the methods used in detecting the intrusion detection system is by implementing Naïve Bayes algorithm. However, Naïve Bayes has a problem when one of the probabilities is 0, it will cause inaccurate prediction, or even no prediction was found. This paper proposed two modifications for Naïve Bayes algorithm. The first modification eliminated the variable that has 0 probability and the second modification changed the multiplication operations to addition operations. This modification is only applied when the Naïve Bayes algorithm does not find any prediction results caused by zero probabilities. The results of this research show that the value of precision, recall, and accuracy in the modification made tends to increase and better than the original Naïve Bayes algorithm. The highest precision, recall, and accuracy are obtained from modification by changing the multiplication operation to the addition. Increasing precision can reach 4%, increasing recall reaches 2% and increasing accuracy reaches 2%.

Abstract

Salah satu kegiatan yang harus diikuti oleh mahasiswa tingkat akhir untuk memperoleh gelar sarjana S1 adalah Pendadaran. Pendadaran di Fakultas Teknik Universitas Jenderal Soedirman (UNSOED) terdiri dari beberapa proses yaitu pendaftaran, penjadwalan pendadaran, dan pengelolaan nilai. Permasalahan yang terjadi dalam pengelolaan proses pendadaran di Fakultas Teknik UNSOED adalah pengelolaan pendadaran pada proses–proses tersebut dilakukan dengan mencatat data dalam buku dan papan tulis. Hal ini menyebabkan proses pengelolaan pendadaran menjadi kurang efektif dan efisien, kekurangan tersebut akan mempersulit kinerja dari staff bapendik, dan dalam hal ini tentunya akan menghambat bagi dosen penguji dan mahasiswa. Untuk mengatasi permasalahan tersebut, penelitian ini telah mengembangkan sebuah sistem informasi pengelolaan pendadaran (SIPENDAR) di Fakultas Teknik UNSOED. Ada beberapa tahapan yang dilakukan dalam pengembangan SIPENDAR yaitu pengumpulan data, analisis dan perancangan, tahapan pengembangan SIPENDAR, dan pengujian sistem informasi. Pengembangan SIPENDAR menggunakan framework Laravel dan menggunakan MySQL sebagai Database Management System. Pengujian dilakukan menggunakan pengujian blackbox dan Mean Opinion Score. Dari hasil pengembangan dan pengujian dapat disimpulkan bahwa SIPENDAR dapat digunakan untuk mempermudah dalam proses pengelolaan pendadaran di Fakultas Teknik UNSOED.
