Analisis Sistem Antrian Pada Pelayanan Poli Jantung RSUD Kota Langsa

Queuing is an activity where parties are waiting to get service. A queuing process starts from the time of arrival to the time of service. Queuing problems are often encountered in everyday life, including in Langsa City Hospital, especially in the cardiac clinic, which has the most patients. The majority of patients in the queue system are elderly (elderly), so good service is needed considering the physical condition of patients who have entered a vulnerable age. The queuing system analysis aims to determine the average number of patients waiting in the system and the length of service at the heart clinic of Langsa City Hospital. In addition, the queue system analysis can help the Langsa City Hospital design an operational service system so that the service process can run optimally. The queue structure model used is a single channel-single phase with the discipline type First In First Out (FIFO). From the queue model analysis results obtained, the cardiac poly care system has an average number of patients waiting at most occurs in the period 08.00-10.00, namely 14 people with a waiting time of about 56.28 minutes. This time is the busy working hour at cardiac poly with a busyness rate of 93%. From the simulation results with two servers using the same model, a busy rate of 50% was obtained with a reduction in the number of people waiting by 12.8 people with a waiting time of about 1.2 minutes.

Pengembangan Titik Miquel Dalam Pada Sebarang Segilima

The Miquel theorem is a theorem that applies to a triangle, namely the inner Miquel theorem and the outer Miquel theorem triangles—then developed on the quadrilateral. As of this writing, it is developed in any of the pentagons. Miquel's theorem development in any pentagon is divided into two cases, namely in the convex and non-convex pentagons. This process begins with the construction of the inner Miquel point in any triangle using the GeoGebra application. While proving the internal Miquel theorem for any pentagon uses a simple concept, namely the concept of circles and cyclic rectangles so that five circles intersect at a point called the inner Miquel point at any pentagon.

Mathematics is an essential subject to study so that it must be pursued in its implementation and possible. The existence of the covid-19 pandemic requires all learning activities to be carried out online. But in practice, online learning experiences several obstacles, especially in learning mathematics. For this reason, the purpose of this study is to describe the constraints in the online-based mathematics learning process (e-learning). This study uses a descriptive method with a qualitative approach. The subjects in this study were students of class VIII SMPN 1 Rawamerta. The research instrument was in the form of a student response questionnaire regarding online-based learning (e-learning), which consisted of seven closed questions and four open questions. Data collection was carried out by distributing the google link form to the student response questionnaire to the research subject. Data analysis was carried out descriptively by testing the validity of the data through triangulation techniques. The results showed that students' obstacles in online-based mathematics learning (e-learning) were technical and personal constraints. Technical constraints are in the form of an unstable internet network, internet quota, and teacher explanations that are not heard clearly. In contrast, unique constraints are the lack of students in understanding the learning material and feeling lazy to take online-based mathematics learning.

Analisis Penyebaran Penyakit Filariasis Menggunakan Model SEIR Di Provinsi Sumatera Utara

North Sumatra is one of the endemic areas of tropical diseases, one of which is filariasis. Filariasis or elephantiasis is a disease transmitted through mosquitoes and can cause permanent physical disability for sufferers. In 2015, there were 127 filariasis sufferers. This number has increased to 164 patients in 2017. As a prevention effort, the government provides mass treatment for people living in endemic areas of the disease. Therefore, this study aims to determine the model of spread and the effect of treatment on these communities. This study uses an SEIR model consisting of susceptible humans (S_h), infected humans (E_h), infected humans (I_h), and immune humans (R_h). The data used is data on filariasis sufferers in North Sumatra in 2010-2019, obtained from the North Sumatra Health Office. The data were analyzed based on the equilibrium point, stability, basic reproductive ratio, and numerical simulation. The results showed that based on the SEIR model, filariasis treatment could suppress transmission in endemic areas.
