Abstract

Pengolahan citra digital merupakan proses yang bertujuan untuk memanipulasi dan menganalisa citra dengan bantuan komputer. Salah satu teknik pengolahan citra yang di gunakan adalah deteksi tepi (edge detection). Deteksi tepi adalah proses untuk menentukan lokasi titk-titik yang merupakan tepi objek. Data yang digunakan dalam deteksi tepi berupa citra digital. Citra dari sudut pandang matematis, merupakan fungsi menerus (continue) dari intensitas cahaya pada bidang dua dimensi f(x,y), dengan x dan y adalah koordinat special dan amplitudo f  pada pasangan (x,y) yang disebut intensitas atau derajat keabuan citra pada titik tersebut. Jika x, y, dan f  semuanya berhingga, dan nilainya diskrit, citra tersebut merupakan citra digital. Menurut Ayu Leonitami, Salah satu metode yang dapat digunakan dalam pendektesian tepi adalah menggunakan metode Robinson operator 3 level. Pendektesian Robinson operator 3 level bukan hanya melakukan proses pendektesian tepi dari arah vertikal dan horisontal saja seperti metode Robert’s operator dan sobel operator lebih sensitive terhadap tepi diagonal, sedangkan robinson operator 3 level  melakukan pencarian tepi dengan menggunakan delapan arah mata angin, sama halnya dengan proses pendektesian tepi prewitt dan kirsch operator bedanya hanya pada nilai kernel (mask).

Abstract

Data adalah sesuatu yang belum mempunyai arti bagi penerimanya dan masih memerlukan adanya suatu pengolahan. Data bisa berujut suatu keadaan, gambar, suara, huruf, angka, matematika, bahasa ataupun simbol-simbol lainnya yang bisa kita gunakan sebagai bahan untuk melihat lingkungan, obyek, kejadian ataupunsuatu konsep. Besarnya ukuran data yang harus dikirim melampaui kecepatan transmisi yang dimiliki oleh perangkat keras yang ada, sehingga masih terdapat delay time yang relatife besar. Selain media penyimpanan seperti floppy disk, hard disk, dan compact disk mempunyai kapasitas yang terbatas. Ada banyak teori dan algoritma  untuk kompresi data, diantaranya metode Huffman, Run- Legth Encoding (RLE), Lempel-Zip-Weleh (LZW), Shanon – Fano, dan beberapa algoritma lainnya.

Abstract

Fuji apples (Malus Domestika) are fruits that contain a lot of antioxidants. Besides the fruit flesh, the apple also contains pectin. Fuji apples are red and have a yellow line. The size of apples can affect the selling price of apples, the determination of the size of apples can be seen from the size of the diameter, measuring the diameter of apples is usually done visually by comparing apples. Based on these problems, a research is needed to develop a system to determine the diameter of fuji apples by using image processing techniques to find the diameter. This measurement process uses the matlab application and tests with the sobel edge detection method and image processing to see the more visible edges of the lines. The results showed that the developed system was able to obtain images and identify the diameter of fuji apples

Abstract

Post Traumatic Stress Disorder is a mental condition where a person experiences panic attacks that are triggered by past experience trauma. Having a traumatic event is a hard thing for anyone. Health services to the community are needed to support a healthy lifestyle. Limitations of health services in the community that are inadequate have a lot of negative impacts on some people who suffer from an illness, especially mental disorders caused by several events. This limitation will become an obstacle due to lack of health infrastructure in terms of consultation of the disease so that sufferers do not know the symptoms such as what they have experienced and how far the disease has been identified, so it is very much needed a solution and alternative in handling the problem of limited health services. By building a system that can help people with the disease, is expected to provide solutions for people with disease to take an action or consultation with an expert based on the system.

Abstract

Lahirnya teknologi informasi komputer dan fasilitas pendukung seprti layanan internet saat ini membuat perkembangan yang sangat luas. Segala informasi-informasi dapat didapatkan begitu cepat membuat jarak dan waktu tidak menjadi masalah. Namaun disamping itu masih jarang ditemukan aplikasi yang dapat mempermudah proses tranlasi suatu kata kedalam bahasa Mandailing-Indonesia. Aplikasi ini dirasa perlu karna banyaknya masyarakat yang belum mengetahui sebagian dari arti bahasa Mandailing itu sendiri. Proses tranlasi kata ini dilakukan hanya dalam bentuk kata dimana kata yang akan dicari akan muncul beserta arti kata tersebut. Pencarian kata meneraapkan prinsip good sufix(dimana karakter yang dicari sejajar dengan karakter yang menyerupainya) serta prinsip bad character(dimana jika tidak memiliki kemiripan langsung dibuang). Dalam skripsi ini akan dibahas tentang cara menciptakan Aplikasi Penerjemahan Bahasa Mandailing-Indonesia yang bermamfaat sebagai pembelajaran bagi masyarakat mandailing Natal itu sendiri, serta untuk mepermudah pengguna dalam proses translasi suatu kata dengan memamfaatkan algoritma knuth morris pratt. Algoritma knuth morris pratt merupakan pencocokan string yang dianggap lebih mudah pada aplikasi ini, dan dirancang menggunakan Microsoft Visual Studio 2008.

Abstract

The aim of the Best Midwife is to find a midwife who is truly responsible for serving patients in a hospital or carrying out their duties in accordance with the legislation. The selection of the best midwife has a problem, namely the best bida selection system that is still manual as long as it is selected in the collection file to apply as a midwife in a hospital. So that the chosen midwife is not in accordance with what is expected, both in terms of ability, responsibility or others. To overcome this, a decision support system is needed using the MOORA method (Multi Object Optimization On The Base Of Ratio Analysis) that can help General Ridos Hospital in the selection of the Best Midwives.

Abstract

The need for schools for applications for selecting student exemplars is something to consider. To meet these needs, a research will be conducted that will build an application and can provide an output recommendation for student election/example. The selection requires several criteria such as Report score, Attendance, Task value, and Achievement. The method used in building the decision support system of student selection is the Multi-Objective Optimization Method On The Basic Of Ratio Analyzer (MOORA). The final result obtained from this research is the application that can help the process of selecting the student / model because this application gives the output of student ranking recommendation from the biggest alternative value to the smallest through MOORA method. The application of decision support system of student elective/exemplar has been in accordance with the specification of functional requirement expected
