Abstract

The Bhakti Pertiwi Kulon Islamic Education Foundation (YPI BP Kulon) is a foundation built to teach Al-Qur'an education and provide social assistance to the community in Gresik City. Financial management at YPI BP Kulon is still carried out on bookkeeping and then transferred to Microsoft Excel and Word every year. The financial records were copied back on a piece of paper more concisely by the treasurer before being transferred, and the transfer process was also assisted by someone else. Bookkeeping is also still separate between each treasurer which can lead to double recording. The formulation of the problem in this study is how to build an information system that makes it easier to manage records and make financial reports. The purpose of this research is to make it easier to manage records and make financial reports. The problem is solved by building a financial management information system using the waterfall model. This study concludes that the problems in YPI BP Kulon are facilitated by reducing and improving current business processes (as-is) to produce recommendation (to-be) business processes by utilizing an information system built using the Laravel framework. User acceptance testing (UAT) testing is then carried out to determine the level of user acceptance of the information system. The results obtained to produce a value of 88.64% which indicates that the user strongly agrees with the system that has been developed.

Abstract

Self-configure is unique to the MANET network, where the network is formed from independent nodes that communicate each other. In MANET, there is a standardized route determination mechanism in sending data packets called the routing protocol. Nodes in a MANET network require energy to communicate, while energy on nodes is limited. Therefore, when testing the network performance, energy consumption is a factor that needs to be taken into account. Temporally Ordered Routing Algorithm (TORA) is a routing protocol that can operate on MANET networks. This study aims to calculate the energy consumption of the MANET network by implementing the TORA protocol. The simulation is carried out with a scenario of increasing the number of nodes from 30, 50 to 70 in an area of ​​1000m x 1000m with an initial energy of 1000 Joules and a simulation time of 100 seconds. This scenario is performed on two different mobility models, namely the fixed grid model and the random waypoint model. From the simulation data, the average value of energy consumption in the fixed grid model for 30 nodes is 65.374 Joule, 50 nodes are 62.262 Joules and 70 nodes are 61.549 Joules. Whereas the random waypoint model for 30 nodes is 62.807 Joules, 50 nodes are 55.808 Joules and 70 nodes are 54.388 Joules. With the scenario of increasing the number of nodes there is a decrease in the average value of energy consumption in the two mobility models, this is due to the multi-route mechanism in the TORA.

Abstract

Melon fruit has many benefits and vitamin content that is useful for health. There are various types of melons that are superior in Indonesia, one of which is the Sky Rocket Melon. This type of melon is round and has a thick, green rind. The entire surface of the skin is covered with gray nets and has greenish yellow flesh. Currently, there is no technology that can determine the sweetness level of a melon. To find out, it is necessary to split or slice some of the flesh. This method is considered very impractical, so it takes a technological innovation only with digital image analysis. This research uses the Gray Level Co-occurrence Matrix and Support Vector Machine methods. In this study, using variations in the value of d = 1, 2 and angular direction θ = 0 °, 45 °, 90 °, 135 ° with 5 features, namely contrast, homogeneity, energy, dissimilarity and correlation. The detection of melon fruit classes is divided into sweet and unsweetened classes using the Support Vector Machine (SVM) by testing 3 kernels, namely Linear, RBF and Polynomial. This study used a Raspberry Pi camera to take pictures of melons with a distance of 10 cm detected by the ultrasonic sensor. Melon detection results will be displayed on the 16x4 LCD. In ultrasonic sensor testing, an average error of 1.97% was obtained with an ultrasonic sensor accuracy of 98.03%. In testing this system, the highest accuracy was obtained by the RBF kernel with a variation of the distance d = 2 and the angular direction θ = 45 °, which was 86% with an average computation time of 8.5403 seconds.

Abstract

The library is considered as a convenient place to read, because the library provides a collection of books and other publications services that are provided to the general public or certain groups. Lots of information can be obtained from the library includes scientific, recreational, religious and entertainment that are human needs. However, according to a survey conducted by UNESCO in 2015 stated that the reading interest of Indonesian society is very low. The lack of interest in reading the community can be affected by several factors such as, the minimal number of libraries and the lack of decent facilities in the library. For example, the more extensive a library, the more variations of book categories and certainly directly proportional to the large number of shelves arranged. Doing a random search manually is the way that most often done, so it will wasting time, especially if the library visitors are visiting the library for the first time and don't know the location of the shelves and the arrangement of the book placement. With the research located on the white label room of the central library of Brawijaya University, the writer made an Arduino-based system which was planted in a book basket, which in the system contained a list of book categories in the library as well as the shelf location where the books were stored. The visitors only need to select the category of books that they want to borrow then the system will process it. The resulting output is the shortest bookshelf route through the LCD on the system by first mapping the existing bookshelves in the library by calculating the shortest distance of the book sought on the nearest shelves from the starting point. With the research located on the white label room of the central library of Universitas Brawijaya, the results from 10 random route search samples the system succeeded in determining the right route with an accuracy value of 100%. It is proven that the system works well besides of that the kind system is an embedded system that is installed in a book basket, so it will make it easier for the visitors if they want to borrow a lot of books in large quantities. On another test was done by testing the execution time required by the system to find the shortest route, the results of 10 tests using random samples only require a very short time with an average of 4.2 milliseconds.
