Therefore, it needs a good incentive to develop a faster and more effective method to predicting the interaction between compound and protein. Predicting the unobserved link of CPI can be done with Ant Colony Optimization for Link Prediction (ACO_LP) algorithms. Each ant selects its path according to the pheromone value and the heuristic information in the link. The path passed by the ant is evaluated and the pheromone information on each link is updated according to the quality of the path. The pheromones on each link are used as the final value of similarity between nodes. The ACO_LP are tested on benchmark CPI data: Nuclear Receptor, G-Protein Coupled Receptor (GPCR), Ion Channel, and Enzyme. Result show that the accuracy values for Nuclear Receptor, GPCR, Ion Channel, and Enzyme dataset are 0.62, 0.62, 0.74, and 0.79 respectively. The results indicate that ACO_LP has good accuracy for prediction of CPI.</p> 2019-10-29T04:29:12+00:00 ##submission.copyrightStatement## Penerapan Metode MOORA pada Sistem Pemilihan Bibit Cabai (Kasus: Desa Bandar Siantar Kecamatan Gunung Malela) 2019-11-26T04:12:05+00:00 Chairul Fadlan Agus Perdana Windarto Irfan Sudahri Damanik <p style="text-align: justify;">Red chili is one of the plants that is often used as a complement to spices in Indonesian society and makes chili plants one of their main crops. Some farmers often find it difficult to determine which chili seeds are good and resistant to viruses. In addition, farmers are also difficult to determine good chili seeds at affordable prices. The difficulty of determining which chili seeds are good often makes some farmers fail harvests and suffer considerable losses. This research was conducted in the village of Bandar Siantar, Gunung Malela District. Data is obtained by interviewing and observing directly to chili farmers. This study uses a decision support system technique with the Multi-Objective Optimization method on the basis of Ratio Analysis (MOORA) which can help farmers to determine good chili seeds. The assessment criteria used were the price of seeds (C1), Harvest Period (C2), Fruit Length (C3), Fruit Weight (C4), Chili Disease (C5), Number of Branches (C6) with 8 alternatives, namely: Lado (A1), Taro (A2), Belinda (A3), TM (A4), Kripsy (A5), Tebing (A6), Indra Pura (A7) and Keling (A8). The results of applying the MOORA method in choosing chili seeds are the type of Lado (A1) chili with a value (Yi (max) = 0.2080) becomes the first recommendation, TM (A4) with a value (Yi (max) = 0.2071) being ranked second and Indra Pura (A7) with a value (Yi (max) = 0.1974) becomes third place. This research is expected to help farmers in determining good chili seeds so that they can help the economy of the farmers and avoid crop failure, especially in the village of Bandar Siantar, Gunung Malela District.</p> 2019-10-30T07:46:09+00:00 ##submission.copyrightStatement## Pengembangan Aplikasi Listening Test Berbasis Android 2019-11-26T03:09:20+00:00 Rokhimatul Wakhidah Moh.

In Indonesia, that kind condition is a common situation. But, to handling this situation in this global era is more difficult because many children choose going to another city or another region to do some activity like taking a job or going to college. It gives an impact to their parent especially when their parent is too old and needs to be cared. This motivation in this paper is based on this kind problem. The development of application uses Waterfall. The system must meet the requirement so not just technichal development is performed, social study must be conducted in the process. We use several testings such blackbox testing, server testing, and usefulness identity. Commonly, we got unsatisfied result based on testing, so some repairement must be conducted.</p> 2019-11-21T07:21:01+00:00 ##submission.copyrightStatement## Implementation of User Management in a Laboratory with a Linux Primary Domain Controller 2019-11-21T12:21:30+00:00 Dhiemas Aditya Oktara Rahmat Suhatman Ibnu Surya <p>The development of network technology now allows many applications that can be done with computer networks. This can be seen from the needs of educational institutions for computer networks.&nbsp; One of them is the Polytechnic Caltex Riau (PCR). The use of computers in the laboratory has not yet applied the concept of user management, so that the data stored on the computer can be accessed by more than one user which causes data to be reduced further. One way to overcome this problem is to implement a Primary Domain Controller (PDC), a server that can store and manage computer activities. Requires the client to have an account to log in to the computer and have their own storage media. From the test results obtained by the average received users log in, directory access and application by 96% and from the results of tests that have been done on average to CPU usage of 4% and memory usage by 37%. Can reduce from testing carried out to 30 users, using CPU and memory increases along with the number of clients who carry out activities and it takes a pause when logging in so that all users can access the server.</p> 2019-11-21T12:21:29+00:00 ##submission.copyrightStatement## Model Arsitektur Smart Library di Perguruan Tinggi Se-Kota Batam 2019-11-21T15:22:57+00:00 Holong Marisi Simalango Muhammad Khaerul Naim Mursalim <p>Design of smart library architecture model is a new architectural model of integrating library information systems in several universities that still use WebApp but are local, so that it is expected to be connected to the new architectural design.

Emotional intelligence is not the same person, intelligence is influenced by the family environment, age, and physical. High or low emotional intelligence influences how to interact and work. Individuals who have low emotional intelligence tend to have individualistic traits and cannot work together in teams, for that every company or agency needs to conduct tests on prospective employees. IQ and EQ tests conducted by companies to prospective employees so far have been done manually, so that problems often occur such as the test taker takes a long time to correct answer sheets, errors in calculating scores and reports of long test results when the test participants are in the amount big. Given the company's mistakes are often too late and wrong in making decisions to accept the right employees, for that we need to make an expert system that can help companies in conducting EQ tests for the selection process of prospective employees in accordance with the desired criteria. Expert system that is designed using the method of forward chaining is a method of searching or tracking information starting from existing information and combined with the rules to get a conclusion. Expert System Design uses an object oriented approach and PHP programming language so that it can be used to help companies, especially in the Human Resource Department (HRD) in the selection of prospective employees.</p> 2019-11-25T05:19:20+00:00 ##submission.copyrightStatement## Riau Folklore Book Ketobong Keramat Based on Markerless Augmented Reality (AR) with User Defined Target Technique 2019-11-25T05:33:32+00:00 Michael Michael Anggy Trisnadoli Rahmat Suhatman <p>Folklore is a story that has been passed down from generation to generation, where each region has its own folklore. In Pelalawan District, there’s a folklore called Ketobong Keramat, where the folklore telling a story about a Magical Doctor who was willing to sacrifice his personal interests to help the King of Pelalawan.
