Areca palm has been widely planted by the people of the Asahan Regency. This plant is cultivated not only by the farmers, but also by many people living in this regency. Therefore, an expert system is needed to help villagers in detecting areca palm desease. In areca palm cultivation, pests and diseases attack always happen. The purpose of this research is to apply an expert system as a tool to diagnose and also provide advice for control. This expert system, in the form of a consultation scenario, can be done by answering every question (yes or no); all answers are compared to the areca palm plants needs based-on expert experience. The inference method used is forward chaining. The output of this system is the types of diseases, percentages, symptoms, definitions, treatment, and prevention. Keywords: Areca Palm, Expert System, Forward Chaining.

ABSTRAK - Informasi kampus merupakan salah satu kebutuan yang sangat dibutuhkan oleh mahasiswa dan dosen disetiap lembaga pendidikan. Pada jurusan Teknik Informatika penyebaran informasi yang dilakukan masih menggunakan cara manual yaitu dengan memberikan secara lansung dan menempelkan pengumuman pada papan pengumuman yang berada didepan sekretariat jurusan, namun cara tersebut tidak efisien karena tidak semua mahasiswa atau dosen selalu hadir dan mengecek papan pengumuman. Aplikasi papan informasi digital merupakan aplikasi yang dibangun untuk memaksimalkan penyebaran informasi kegiatan kampus pada Jurusan Teknik Informastika Universitas Asahan, aplikasi ini dibuat menggunakan pemodelan Unified Modeling Languange (UML)Keywords— Informasi, Papan Digital, Aplikasi

Model Dan Simulasi Prototype Rangkaian Digital Konversi Gerbang AND, OR, NOT Menjadi Gerbang NAND Dan NOR Helmi Fauzi Siregar; Muhammad Dedi Irawan

Dalam mempelajari rangkaian digital, khususnya pada materi gerbang logika pada sistem digital ada sebuah Rangkaian kombinasi Gerbang AND, OR, NOT yang dapat dikonversi ke Rangkaian Gerbang NAND dan NOR. Pada konversi Rangkaian kombinasi tersebut dapat dilakukan dengan 2 (dua) cara, yaitu Melalui penyelesaian persamaan logika/boolean dan langsung dari gambar padanan. Gerbang NAND dan NOR ini disebut juga Rangkaian Multilevel yang artinya dengan mengimplementasikan Gerbang NAND atau NOR, akan ada banyak level / tingkatan mulai dari sisi input sampai dengan sisi output. Pada penelitian ini fokus pembahasan pada proses konversi dari Rangkaian kombinasi AND, OR, NOT ke Rangkaian menggunakan Gerbang NAND dan NOR. Dengan ini penelitian akan membuat suatu Prototype Rangkaian kombinasi Gerbang AND, OR, NOT yang dikonversi dengan Rangkaian Gerbang NAND dan NOR sebagai model alat simulasinya.

Data is important information both personal, group and company. Because of the importance of the data, many parties have kept the data very confidential so that it is not publicly recognized. But it cannot be denied that data can be stolen by unauthorized people. Request the data to be unsafe. A technique is needed to move data, namely by using cryptography. One of the existing cryptography techniques is classical cryptography such as vigenere cipher. However, this classic has a low level of security so it needs to be upgraded again. Then a combination of cryptography algorithms using modern cryptography, Electronic Code Book (ECB) is carried out. Using a combination of these two algorithms will improve data security.

Abstract - White oyster mushroom cultivation is a micro business which is mostly in the territory of Indonesia is very good and suitable because the temperature is suitable for the growth of various types of mushrooms. At this time it can be cultivated in a mushroom house. For optimal mold growth, temperature and humidity must be maintained according to the conditions of their natural habitat. The amount of oyster mushroom production can be increased by taking into account the factors that influence the growth of the oyster mushroom itself. Even farmers can experience failure in production or often called crop failure. Decision support systems can be used in determining the increase in production. In this study also implemented the fuzzy logic method in Increasing the production of oyster mushrooms. It is hoped that farmers can use it to increase the production of oyster mushrooms and prevent crop failure. Application results are expected to be a decision support system for farmers in the maintenance and production of oyster mushrooms. Starting from determining the planting media, see the temperature and humidity.Keywords - Fuzzy Logic, Decision Support System, Increase, Amount of Production and White Oyster Mushrooms Abstrak - Budidaya jamur tiram putih merupakan usaha mikro yang sebagian besar di wilayah Indonesia sangat bagus dan cocok, karena temperaturnya yang sesuai untuk pertumbuhan berbagai jenis jamur. Pada saat ini dapat dibudidayakan pada rumah kumbung. Agar pertumbuhan jamur dapat optimal maka temperatur dan kelembaban harus dijaga sesuai kondisi habitat alaminya. Jumlah produksi jamur tiram dapat ditingkatkan dengan memperhatikan faktor-faktor yang mempengaruhi pertumbuhan jamur tiram itu sendiri. Bahkan para petani dapat mengalami kegagalan dalam produksi atau sering disebut gagal panen. Sistem pedukung keputusan dapat digunakan dalam menentukan peningkatan produksi. Dalam penelitian ini juga di implementasikan metode logika fuzzy dalam Peningkatan produksi jamur tiram. Diharapkan dapat digunakan para petani dalam Peningkatan produksi jamur tiram dan mencegah terjadinya gagal panen. Hasil Aplikasi yang diharapkan dapat menjadi sistem pendukung keputusan kepada petani dalam pemeliharaan dan produksi jamur tiram. Dimulai dari menentukan media tanam, melihat temperatur dan kelembaban. Kata kunci - Logika Fuzzy, Sistem Pendukung Keputusan, Peningkatan, Jumlah Produksi dan Jamur Tiram Putih

Abstract - Savings and loan money is one of human needs. Where savings and loans are something that is very necessary to support the development of economic activities and improve living standards. In universities, there are many students who spend money to pay for their tuition fees. Among these students, there are fairly poor people. The author took the initiative to make a savings and loan application that is useful for students, if they need funds to complete lecture administration at any time. Students can also set aside a portion of their allowance to be stored in the application. In this way, students can reduce the burden a bit regarding the problems of lecture administration. Based on the description above, the author raised the research title with research conducted directly on the students of the Asahan University Faculty of Engineering with the title "Designing Student Loan Savings and Loan Applications for the Faculty of Engineering, Asahan Web-Based University". Keywords - applications, savings and loans, money, fees, students, web
