Abstract

Penyebab terlambatnya distribusi barang, berkurangnya produktivitas karyawan serta roda ekonomi yang tidak cukup baik salah satunya adalah kemacetan. Kemacetan sendiri akibat pengaturan lampu lalu lintas yang tidak dinamis sehingga pengaturan jalur tidak sesuai kondisi yang ada. Jakarta adalah salah satu kota terbesar dan termacet ke-2 di Asia, perlu penanganan serius seperti pengaturan lalu lintas yang baik sehingga mengurangi kemacetan dan kerugian ekonomi lainnya. Sistem lalu lintas dengan menerapkan kemampuan kecerdasan buatan lebih memungkinkan digunakan pada kota besar seperti Jakarta. Berdasarkan masalah tersebut, dilakukan penelitian pada sistem lalu lintas tiga jalur atau sepertigaan dengan penambahan sensor inframerah pada lampu lalu lintas dan penambahan waktu setiap terdeteksi kemacetan dan jalur lancar. Sistem kontrol lampu lalu lintas menggunakan metode Fuzzy Logic Mamdani. Metode Mamdani membandingkan berdasarkan kondisi dari setiap sensor infrared sebagai variabel masukan panas dari kendaraan pada setiap jalur, semakin padat jalur semakin panas jalur tersebut. Deteksi kemacetan ini akan membantu sistem dalam mengendalikan waktu lampu hijau, lampu berdasarkan kondisi kemacetan. Berdasarkan percobaan, prototipe merespon jalur yang dipenuhi kendaraan, prototipe menambahkan waktu lampu hijau sesuai dengan kondisi yaitu 0 detik, 5 detik, 10 detik, dan 15 detik. Namun, ketika jalanan tidak terdeteksi oleh kemacetan lalu lintas, lampu hijau akan kembali normal pada 15 detik tanpa waktu tambahan

Abstract

Financial deviation are often found in various agencies as occurred in 16 PTN (Merdeka.com) in the financial reporting of a lot of unfairness in the BPK (Supreme Audit Agency) report, this happens because the mechanism of reporting in the internal University has no financial audit. It is necessary to create an application that can detect the occurrence of deviation in proposals and financial reports that impact on unnatural reports, this study using the Greedy and K-Mean Clustering algorithms. The application of academic financial detection at University XYZ has the function of making proposal, financial report, monitoring from the person in charge to facilitate supervision and the existence of notification if there is budget unreasonable. The application of Greedy and K-Mean algorithms to the application can be applied by simulating proposals and reports that have reasonable and unreasonable prices, showing success with the notification of each proposal and unnatural reports on finance.

Abstract

The exchange of information is very easy by using the internet as a liaison from the party who sends information to the party receiving the information. It is also easier for unauthorized parties to obtain information that will be sent from the sending party to the recipient via the internet. So that information requires security features. Encoding is a security technique to change information in the form of text, digital images, audio, video into information that has no meaning or is random. If the party who has the information that has been encoded does not have the key to open the encryption then the information cannot be read because it does not have a specific meaning. Insertion is a security feature wherein an information will be entered into a container media or the information is hidden in the container media. At this writing will be focused on creating a system that can encode, decrypt passwords, insert an information into a container media and extract information from a media that can be a digital image with the format: jpeg, bitmap, and png which is useful for increasing the level of security from an information. Encryption algorithm is an algorithm that converts an information (plain text) into a randomized information ( ciphertext) uses the specified key from the sender and recipient. The encoding algorithm used is the Hill Cipher algorithm. Which will be combined with the Least Significant Bit method as a method in the information insertion process. LSB will change every last bit value of each pixel in the cover image according to the binary value of the message in sequence, so that the result of the stego image will not change significantly if seen by the human eye.

Abstract

For school children, offices, and students stationery is needed. Because stationery are needs to take notes important things. Although in the current digitalization era learning materials can be obtained online to minimize the use of stationery, it doesn't rule out the possibility that stationery are needed indeed for other activities. Therefore, stores that provide various types of stationery must be able to know the level of purchases on products ?products that are more often purchased by consumers so that the supply of stock products can be more focused on products that are more often purchased by consumers. At this writing, the author uses the Apriori algorithm that performs itemset frequencies to get association rules that meet the minimum support requirements and minimum confidence requirements with a number of itemset in the overall transaction to achieve the percentage of support and the percentage of confident value in determining items that are often sold in every transaction. By using the Apriori algorithm which has an accuracy rate of around 70%, it can predict the stock of product sales at the XYZ store. The purpose of applying the Apriori algorithm at this writing is to find out the level of purchases on products that are more often purchased by consumers based on existing transaction data to provide a more efficient stock of sales products.

Abstract

Poverty in Indonesia occurs almost in various regions, one of them is the Jakarta region. Although Jakarta is a fairly large area and is one of the most developed regions, there are still some families that are still poor and unable to send their children to school, so the government issued the Kartu Indonesia Pintar program to help poor families. Although this program can really help poor families to send their children to school, sometimes there are some families that are classified as poor but do not even get the benefits of this program, but a family that can afford it get the benefits. The purpose of this paper discusses the application of data mining using the algorithm K-Means Clustering in grouping families classified as poor, simple and rich in terms of the amount of monthly income, average monthly expenditures and total assets owned, as well as the number of children who are classified according to elementary level , Junior high and high school to determine the amount of assistance that will be given based on the level. The resulting output will be in the form of a 3-table report in which each table contains data on families classified as poor, simple and rich, where this simple group can later be reviewed whether they are entitled or not to get the assistance of the Kartu Indonesia Pintar program. From the results of testing using 200 family data, the accuracy of the results of the application of K-Means Clustering was 69%.
