Abstract

Abstrak Studi untuk mempelajari perilaku elemen antrian (waktu tunggu nasabah, waktu pelayanan, waktu menganggur teller dan sebagainya) dalam suatu sistem dapat ditinjau dengan teori antrian. Elemen antrian, terutama waktu pelayanan saat transaksi, dapat dijadikan tinjauan dalam meningkatkan kepuasan nasabah. Kecenderungan kesibukan aktivitas pelayanan di bank adalah merata setiap harinya. Kondisi ini berbeda dengan Bank BNI 46 Cabang Universitas Kuningan yang mempunyai antrian yang sangat panjang pada waktu menjelang UAS. Model antrian bank tersebut dianalisis dengan mempertimbangkan distribusi pola kedatangan, distribusi pola pelayanan dan jumlah teller menggunakan  fit test. Hasil uji ini menunjukkan pola kedatangan berdistribusi Poisson dan pola pelayanan berdistribusi eksponensial. Dan karena jumlah teller adalah 1, maka mengikuti notasi Kendall, model antrian bank adalah M/M/1. Simulasi pelayanan transaksi pada bank dilakukan untuk melihat kecenderungan perilaku elemen antrian. Simulasi menunjukkan semakin besar tingkat pelayanan, semakin besar peluang waktu menganggur teller. Akan tetapi, semakin besar tingkat pelayanan, banyak nasabah dalam antrian dan dalam sistem antrian akan semakin sedikit. Demikian juga dengan waktu rata-rata nasabah dalam antrian dan dalam sistem antrian.Kata Kunci: Model Antrian, Perilaku Elemen Antrian, Simulasi. Abstract A research to study behavior of queue elements (customer waiting time, service time, idle time teller and so on) in a system can be reviewed with queuing theory. The queue element, especially the transaction time, can be used as a review to improve customer satisfaction. The tendency of busy activity in bank service is evenly distributed every day. This condition is different from BNI 46 Bank branch Kuningan University which has a very long queue at the time before final examination. The bank queue model is analyzed by considering the distribution of arrival pattern, service pattern distribution and number of teller using fit test. The results of this test show the pattern of arrival of Poisson distributed and exponential distribution service pattern. And since the number of tellers is 1, then following Kendall notation, the bank queue model is M / M / 1. Simulation of transaction service at bank is done to see tendency of queue element behavior. Simulations show the greater the level of service, the greater the chance of idle time teller will be. However, the greater the level of service, the more customers in the queue and in the queuing system will be less. Likewise, the average time the customer is in the queue and in the queuing system. Keywords: Queue Model, Behavior of Element Queue, Simulation.

Abstract

Abstact Textbooks have an important role in the learning process. In addition as a reference material, also have the potential to affect student learning. In this study, carried out a survey of mathematics education students. Students were asked to describe how they used textbooks. The survey was conducted by giving questionnaires and interviews about what components are used, when students look at each component, the reason for these components as well as the students see what difficulties encountered when used textbook. Data collected was processed using descriptive statistics as well as to determine there are differences in the use of good text books for each component or components in pairs using Cochran’s Q test and McNemar Test. The result show that students tend to use the sample chapter to build their understanding of math concept than the chapter text description. Difficulties experienced when students understand basic concepts such as definitions and theorems which causes difficulty in working on.

Abstract

One of the medical equipment that is often used in hospitals is infusion; however, the infusion monitoring system is generally still manual so that medical staff must constantly monitor the infusion device condition, which is requiring more effort and time. In this study, a 500 ml Ringer’s lactate infusion fluid monitoring system was developed based on the internet of things (IoT) using the message queuing telemetry transport (MQTT) communication protocol and an IoT cloud server system using the MQTT Dash. This infusion fluid was chosen as it is the most widely used infusion fluid. The HX711 load cell was used as a sensor to determine the weight of the infusion fluid. In addition, the NodeMCU ESP8266 microcontroller was used since it is equipped with a WiFi module called the ESP8266 module, hence it can support the implementation of IoT systems. The MQTT protocol was used to send the data to users. It was then connected to the MQTT Dash application as a monitoring medium for medical personnel. The system’s performance based on the performance of the HX711 load cell sensor in terms of the accuracy of reading the weight of infusion fluids was very good. It is evidenced by the average error percentage value of 0.08% to 0.64%, meaning that load cell sensor works well as it remains within the error tolerance limit of 5%. Meanwhile, the quality of service (QoS) test revealed that the results of the average delay on all systems ranged from 0.014 ms to 0.023 ms. According to the telecommunications and internet protocol harmonization over networks (TIPHON) standards, these values are considered very good. After that, the average of packet loss testing results on all systems were 0% to 0.01%. According to the TIPHON standards, these values are likewise classified as very good.
