This system contains a lattepanda as the main processing unit and an adjustable interface to suit the needs of the cultivated plant. It gets input from temperature sensors, light sensors and humidity sensors and displays the output on the LCD screen module. The system results are simulated with the help of simulation software. And then the evaluation of the experimental results of the control system applied to aeroponics is based on environmental factors. The proposed lecture grows on an aeroponic device. The green plant was chosen to build an automatic control system in aeroponics. The results show that the system can be more efficient in saving labour and increasing the economic value of the product.

In the face of the need for rapid validation for the process of legalizing copies of diplomas and grades. But in the legalization must have good security. Where it aims to overcome the threat of modification and falsification of digital documents in the form of diplomas. This study aims to reduce the risk of falsification of diploma digital documents by using the concept of Digital Signatures which are expressed on copies of documents, using the SHA-1 algorithm will be able to produce digital signatures based on data available on diplomas and diploma legalization dates. Digital marking method designed to be applied in a person's diploma validation system or student validity by applying the SHA-1 algorithm. Where the results of a digital signature will be applied to digital documents as proof of diploma legalization for the validity of digital documents.

The Internal Quality Assurance System or known by the term SPMI has been understood by the Chancellor, Deputy Chancellor, Dean and Chair of the Study Program but for the ordinary staff and lecturers of SPMI is not very well understood. This is caused by the absence of a discussion forum or a place to share knowledge about the internal quality assurance system to staff and lecturers where one of the tasks is to run operations to support the operation of SPMI. The solution to overcome this is by building a Knowledge Management System which acts as a forum for sharing the knowledge that can be utilized to increase the knowledge of staff and lecturers regarding internal quality assurance at their respective colleges.

In the world of cryptography, chaos theory is used to generate numbers at random. This random number will then be used as the key in performing the encryption process. The chaos function is a function that has a sensitive nature to the initial value, meaning that a small change in the initial value will result in a major change in the value of the next function. Such properties can be applied in cryptography to maintain data integrity, especially in stream cipher cryptographic algorithms such as vigenere cipher, vigenere cipher algorithms have problems with very low security levels. In the vigenere cipher algorithm a key, called the initial key, is made of a key longer than the initial key called a key stream that is very easy to solve. The application of chaotic function in vigenere cipher can improve the security of the key used, since the chaos function can generate random numbers for the initial key on the vigenere cipher algorithm that has the sensitive properties at the initial value.

The focus of this research is to propose problem-solving methods in determining outstanding employees for award. The goal is to get the most potential employees according to the criteria expected by the decision maker. Evaluation of employee performance to obtain high achieving employees depends on the discipline of work and administration, reliability, maturity and personal integrity, morale, communication and working principle, quantity and quality of work and concern for organizations that are interconnected with each other. With so many alternative choices and the number of factors to consider makes it difficult for decision makers to make choices. The problem is almost impossible to be analyzed by the human brain through the relationship between all the criteria along with the alternative to determine a truly objective. Decision support system with profile matching method is the solution to determine the most potential employees. This method determines the weight value for each attribute and then proceeds with a ranking process that will select the best alternatife of the most potential employee. The result of employee performance evaluation using 200 employee appraisal data obtained accuracy level of 93% where 193 data in accordance with the value obtained from employee performance evaluation process.

Because in the case of services, customer satisfaction is crucial that the business can survive or not in competition with other similar businesses. In services voucher electrically, there have been people who run the business. However, the infrastructure used to tend manually. This will have an impact if the traffic of transactions made high enough. Most of the state of the waiters vouchers electrical services have many used cell phones manually and quite a few are registering more than one voucher distributor electrically to one type of provider. This study designed a system to SMS Gateway Service System for Improving Customer Care Toll On Sale Electric. This system works for diverting the path to the SMS Gateway that contains more than one port. The transfer line at the SMS Gateway of decisions made based on the data processing that takes into account the possibility-the possibility of ports being used so that each transaction can be performed optimally.

Sebelum penggunaan sistem pendataan obat ini diberikan pihak klinik bidan supiani dalam mendata obat dengan melakukan pencatatan di sebuah kertas biografi pasien yang mana di kertas tersebut akan tersimpan riwayat berobat dan jenis penyakit yang pernah diderita oleh pasien. Sistem manual tersebut menyebabkan kerumitan dalam pelayanan yang diberikan pada pasien, karena pasien akan menunggu sangat lama dikarenakan administrasi akan melakukan pencarian dan pembongkaran data apabila pasien tersebut sudah pernah berkunjung atau berobat, jika baru pertama sekali ingin berobat pihak administrasi harus mencari no urut dan mencatat nama pasien dan biodata pasien sehingga menimbulkan waktu yang cukup lama dalam proses administrasi. Dengan sistem informasi pendataan obat yang diberikan pada paraktek umum bidan supiani, sangatlah membantu dalam hal perekaman data, penyimpanan berkas dan sampai pelayanan untuk pasien menjadi lebih cepat dan efisien. Satu hal lagi pihak paraktek umum bidan supiani dapat melaukan rekapitulasi dalam satu hari obat apa saja yang berkurang. Hal ini sangat memberikan kontribusi yang sangat besar bagi pihak praktek umum bidan sehingga dapat meningkatkan pelayanan berobat pasien. Hasil evaluasi setelah diberikan pelatihan mengalami peningkatan setelah diberikan pelatihan dan pendampingan dalam pelatihan penggunaan sistem informasi pendataan obat yang dikembangkan oleh Tim, yakni sebesar 88,75%. Hasil tersebut menunjukkan bahwa peningkatan pengetahuan dan keterampilan peserta kegiatan setelah mengikuti rangkaian kegiatan masuk dalam katagori "Sangat Baik.

Kriptografi merupakan langkah-langkah logis bagaimana menyembunyikan pesan dari orang-orang yang tidak berhak atas pesan tersebut dengan melakukan pembangkitan kunci, enkripsi dan dekripsi. Kriptografi bertujuan untuk memberi layanan keamanan (yang juga dinamakan sebagai aspek-aspek keamanan . U ntuk dapat menggunakan teknik kript o grafi, dibutuhkan sebuah metode. Oleh sebab itu peneltii menggunakan metode Stream Cipher. Stream cipher merupakan cipher yang hamper sama dengan caesar cipher (cipher yang menggeser urutan alphabet sehingga urutannya alfabetnya berubah), tetapi cipher ini mempunyai kunci yang unik, yaitu menggunakan karakter sebelumnya sebagai kunci. Namun peneliti akan membandingakan metode stream cipher dengan metode caesar cipher agar dapat diketahui metode yang mana yang keamanannya lebih baik.

Permainan ini pertama kali ditemukanoleh orang-orang Arab dan Persia. Kata catur berasal dari bahasa sansekertadari kata chaturanga yang berarti “empat divisi ketentaraan”. Kemudian permainan catur mulai berkembang dan menyebar keseluruh dunia hingga saatini. Permainan ini selalu mengandalkan strategi sebagai daya tariknya danbiasa disebut sebagai strategi abstrak. Kebanyakan orang memainkanpermainan ini hanya sebagai hiburan atau rekreasi. Kekhalifahan Ali bin Abu Tholib merupakan salah satu pencetus permainan catur ke seluruh penjuru dunia dan ini terjadi pada abad ke-6, bahkan Ali bin Abu Tholib sendiri juga memainkan permainan catur dan memopulerkannya , Muhammad Khalid bin walid merupakan panglima perang pada masa itu juga ikut memainkan permainan catur yang strateginya di gunakan untuk dalam peperangan. Said bin Jubair yang juga merupakan sahabat Nabi juga bisa memainkan catu...
