Abstract

Small and Medium Industries (SMIs) have a very important role as a driver of the economy in Indonesia because SMIs can function as a provider of employment for a number of people who are not accommodated in the formal sector. SMIs also contributes to the formation of Gross Domestic Product (GDP) and as a source of foreign exchange. However, SMIs experienced obstacles in the fields of marketing, business networks, and information technology. In realizing an independent and developing SMIs, a supporting media is needed which can later be useful as a tool to introduce SMIs to the wider community and align it with other business actors. In addition, the government also needs a media that can be used for licensing data collection, taxes, and as a tool to monitor the development of SMIs. In this case a geographic and web-based geographic information system has been built to meet the need for information on SMIs in the city of Mataram. It is hoped that this system can help the community and the government to find out the information needed easily, quickly, and accurately. Based on the results of the Mean Opinion Score, it shows that the average rating of respondents of website users on the system agrees and strongly agrees to agree worth 67.50%. While the average rating of respondents of mobile users to the system agree and strongly agree is worth 78.33%.

Abstract

The thesis is one of the graduation requirements that students must take to obtain a bachelor's degree. Each student informatics study program who will carry out the Thesis will do several processes, including the process of registration of titles, guidance, registration of Thesis seminars, Examination and judiciary sessions. The thesis administration process is still running manually, where at the time of title registration, students must fill in the form of thesis title. After that, students will wait for the announcement to find out their supervisor as well as the registration of the Thesis Seminar, the examination, and the Judiciary sessions. Students must come directly to the office with the registration requirements. The process requires a long time so that thesis administration services become less effective. Therefore a website-based Thesis Information System was built which aims to facilitate the thesis administration process of Informatics study programs. Based on black box testing, this system was declared to have run well while testing using the MOS method showed that 95.34% of informatics student respondents, 99.33% of non-informatics student respondents, and 100% of lecturers and admin respondents agreed. Therefore this system is suitable for use. Keywords: Thesis, website-based, black box, MOS.

Abstract

Pemberian beasiswa merupakan program kerja yang ada di setiap Universitas atau perguruan tinggi. Bidikmisi adalah program bantuan biaya pendidikan yang diberikan pemerintah melalui Direktorat Jenderal Pendidikan Tinggi. Dalam melakukan penetapan mahasiswa peserta beasiswa bidikmisi pihak Universitas masih menggunakan cara manual yaitu dengan cara melakukan pengecekan kembali data mahasiswa satu persatu di Microsoft excel oleh Subbagian Kesejahteraan Mahasiswa dan hasil seleksi data diurutkan berdasarkan fakultas atau prodi masing-masing. Untuk membantu dalam proses seleksi maka perlu dibangun sistem pendukung keputusan, agar dapat menjadi pertimbangan dalam mengambil keputusan. Dalam sistem pendukung keputusan ini menggunakan 10 kriteria antara lain: penghasilan ayah, penghasilan ibu, jumlah tanggungan, kepemilikan rumah, luas tanah, luas bangunan, jarak pusat kota, mandi cuci kakus, sumber listrik dan sumber air. Didalam sistem pendukung keputusan ini perhitungannya menggunakan metode weighted product. Metode weighted product digunakan karena metode ini lebih bisa memberikan nilai bobot disetiap kriteria kemudian dilakukan perangkingan dari yang terbesar ke terkecil dari hasil perhitungan nilai akhir. Dalam pembangunan sistem ini, menggunakan bahasa pemograman PHP dan database yang digunakan mysql dengan menggunakan framework Codeigniter.

Abstract

Mobile Ad Hoc Network (MANET) is a network consisting of a group of mobile nodes that don't have a fixed infrastructure. This causes the MANET to be vulnerable to attacks that can interfere with the process of communication and data transmission on the network. One type of attack that can attack the MANET is a wormhole attack. The wormhole is an attack on a network where there are two or more wormhole nodes that are interconnected and work together to attack network traffic or discard data packets it receives. Each wormhole node will be connected to each other using a wormhole link. To prevent wormhole attacks, the method that can be used is the Delay Per Hop Indicator (Delphi) method and the Round Trip Time and Topological Comparison (RTT-TC) method. The Delphi detects wormhole attacks by calculating the delay in each hop from the source node to the destination node. Whereas in the RTT-TC, wormhole attacks are detected by calculating the value of round trip time and topological comparison. The Delphi and RTT-TC methods have their advantages and disadvantages. In this study, it was proposed to combine the Delphi and RTT-TC methods to cover the disadvantage of each method.

Abstract

Climate conditions are very influential on various sectors of human life, such as agriculture. Extreme climate can affect the planting and harvest period which can eventually lead to crop failure. Climate forecasting can be done to help mapping the planting period so that agricultural productivity is optimal. Artificial neural network is a method that can be used to forecast climate in the future. In this research, a backpropagation model was used to forecast monthly data on minimum and maximum temperatures, humidity, air pressure, number of rainy days, and rainfall in Mataram city. The accuracy of forecasting result is measured based on MSE (mean square error). Based on the research conducted, the MSE of testing phase are minimum temperature 3.59 x 10-3, maximum temperature 1.97 x 10-4, humidity 2.11 x 10-3, air pressure 2.50 x 10-3, number of rainy days 7.97 x 10-4, and rainfall 1.00 x 10-3.
