Abstract

Utilization of Information Technology can assist clinics in improving the quality of service to patients. Friends of the clinic is an obgyn clinic in the city of Padang and is one of the clinics that has many patient visits. So far, the queuing system for patient registration at the clinic has used technology such as WhatsApp, but with this method there are several obstacles, such as (1) having to involve clinic staff to register patients to get a queue, (2) patients piling up in the waiting room to wait for services, (3) and psychologically has the potential to increase the patient's illness because of the long waiting time. This running queuing system is considered inefficient, so innovation is needed to create queuing applications that can be used by patients independently without involving clinic staff, view doctor's schedules in real time and get queue numbers automatically and queue status can be monitored by patients. With this clinic queuing system, patients will come to the clinic when they are close to the queue number they have, get service without having to queue in waiting in the clinic waiting room. By using the queuing method that is designed, it is expected that speed, accuracy, integration, service improvement, and efficiency of service to patients can be further improved.

Abstract

The research purpose to know the contribution of student interest for the leaning outcomes of basic program at the second year student of Computer Engineering and Networks at the SMK 2 Padang. At the year of study 2014/2015. The research problem is the leaning outcomes for the basic program lesson at the second year student is, there is still many of student knowledge level position below the minimum completeness criteria (KKM) given. The minimum completeness criteria standard for the SMK N 2 Padang with the range 0-100. But the fact only 92.72% of student got less than grades 7.28% of the student got more then 75 good. This research is quantitative with the type of research is correlational. That is the research to find out the level of correlation research variable with the differed contribution variable which is the contribution of independent variables on the dependent variable. The instrument used in collecting the data in this research is the questioner form and the leaning outcomes. To know the student interest, the writer used the questioner compiled with the Likert Scale models. The instrument leaning outcomes using the multiple choice (multiple choice item test). The research data analyzed by using correlation techniques. The analysis data by using the statistical program IBM SPSS computer Statistics 21.  Based on the research that has been conducted of the research population are the students of second year of Computer Program and Networking at the SMK 2 Padang at the year of study 2014/2015 with 55 population students and used total sample of TKJ 1 and TKJ 2. So we can calculate that student interest the leaning outcomes is 79.49%. As the hypothesis test using correlation Pearson product moment between the student interest whit leaning outcomes is 0.572 and get the level t count and df=n-2 for the significant level of 0.05, whit the provisions t count more than t table, then compared it with t table so it can conclude that t count 5.083 bigger than 2.006 t table then Ho is reject and Ha is accepted, it means that there is correlation between student interest towards learning leaning outcomes.

Abstract

A fingerprint recognition system aims to identify individuals. The main challenge in fingerprint recognition is the low quality of the images. This low quality can be attributed to various factors, including oily or dry skin types and the type of fingerprint scanner used. Therefore, efforts are made to improve the fingerprint image quality, as it is a crucial factor in determining the accuracy of fingerprint recognition results. To make dirty fingerprint images more interpretable by both humans and machines, quality improvement is necessary by minimizing the dirty areas. This research aims to enhance the quality of dirty fingerprint images using the Gabor filter method and the learning vector quantization method for testing. The testing is conducted using four images for training in each class. There are a total of 10 classes in this testing, with each class consisting of 10 images. In the testing phase, with 75 dirty fingerprint images, an accuracy rate of 33.3333% is achieved.

Abstract

This study aims to determine the application of the Itrend moment method in determining forecasting of palm fruit production. Oil palm plantations are one of the industrial strategies in Indonesia. Oil palm trees are plants that provide many important roles for humans, such as raw materials that can be used as fuel and produce food oil. Therefore, it is not surprising why there are so many oil palm plantations scattered throughout the archipelago. One of them at Pt. Perkebunan Nusantara III (Persero) Kebun Aek Nabara Utara where the company is engaged in oil palm and rubber plantations. This research is supported by using the trend moment method to facilitate forecasting of palm fruit production. By doing forecasting, it will be easier to find out the amount of palm fruit production just by forecasting some symptoms, such as weather, climate, and temperature. In addition, this method is assisted by using a system, namely a decision support system. Where able to take or determine decisions from a forecasting (forecasting).
