Abstract

Penelitian ini membahas tentang Penerapan Sistem Antrean dalam Menentukan Jumlah Kasir di Supermarket Deco 100 Indrapura. Penulisan ini bertujuan untuk mengetahui seberapa besar tingkat kinerja sistem antrean dengan menerapkan disiplin antrean First In First Out (FIFO) serta menggunakan sistem antrean Multichannel-Single Phase. Hasil dari 7 hari penelitian dengan kondisi 4 kasir diperoleh jumlah pelanggaan rata-rata dalam sistem (L????) adalah 6 konsumen per menit dengan waktu rata-rata konsumen dalam antrean (????????) selama 5 menit dan waktu rata-rata konsumen dalam sistem (????????) selama 10 menit dengan waktu menganggur kasir 2,5% dan total biaya antrean sebesar Rp141.795,00. Kondisi dengan 5 kasir diperoleh jumlah pelanggaan rata-rata dalam sistem (L????) adalah 4 konsumen per menit dengan waktu rata-rata konsumen dalam antrean (????????) selama 1 menit dan waktu rata-rata konsumen dalam sistem (????????) selama 7 menit dengan waktu menganggur kasir 3,9% dan total biaya antrean sebesar Rp116.187. Dapat disimpulkan supermarket melakukan penambahan kasir sebanyak 1 kasir supaya banyaknya antrean yang terjadi pada konsumen dapat berkurang dan dapat dikatakan optimal.

Abstract

Distribution routes are generally a problem for every company, including in the public company BULOG Medan Amplas. Distribution to the Medan Amplas BULOG public company, namely having to serve every stall that is far from the warehouse with scattered locations, and limited vehicle capacity. So far, driver considerations in distributing products have only been based on random intuitions of driver and does not consider the efficiency of the route taken. Therefore, this research uses Clarke and Wright Savings algorithm to obtain optimal mileage by taking into account every consumer demand and vehicle capacity. Calculation results using the Clarke and Wright Savings Algorithm obtained the vehicle mileage of 695.08 km with a savings of 11 km or 1.56%.

Abstract

Penelitian ini mengkaji sebuah permasalahan optimasi untuk masalah pencarian rute. Algoritma Dijkstra adalah salah satu varian bentuk algoritma popular dalam pemecahan persoalan terkait masalah optimasi pencarian lintasan terpendek sebuah lintasan yang mempunyai panjang minimum dari verteks a ke z dalam graf berbobot positif. Tujuan dari penelitian ini adalah untuk memperoleh rute terbaik jalur pendistribusian BBM dari terminal BBM menuju ke beberapa SPBU di Kota Medan. Data diambil berdasarkan data primer berupa data Terminal BBM, SPBU, peta jalan Kota Medan dari Google Maps dan survei kepadatan setiap jalan dapat disusun gambar jaringan jalan dan membentuk sebuah graf. Selanjutnya dari gambar graf dapat diperoleh rute terbaik menggunakan algoritma Dijkstra. Terdapat 2 parameter yaitu panjang jalan dan kepadatan jalan untuk menghasilkan bobot berupa kemacetan yang dihasilkan menggunakan logika Fuzzy. Berdasarkan hasil analisis, diperoleh 7 rute terbaik untuk masing-masing SPBU yang direkomendasikan.

Abstract

Zuhro Bakery is baking factory producing various kinds of bread. In this research, there were three kinds of bread that were studied, they were chocolate, mocha and strawberry flavored bread. The problem in optimalization of the production was modeled into a mathematic model which was the linear program in the form obstacle function and objective function. It was then continued by the deciding variable in integer number as the linear program. Then, it was solved by using Branch and Bound method which previously had counted the variable by using the symplex method. From the simplex method, an integer number result was not found, so the Branch and Bound method was used. QM software was chosen in the research to solve the integer problem. A profit was earned with a sale margin of Rp39.000 or 0,42% from the coorporation’s expected profit by using the Branch and Bound method. The amount of bread produced in the periode of three days were 5.400 consosted of 3.060 chocolate flavored bread, 1.440 mocha flavored bread and 900 strawberry flavored bread with the total profit of Rp9.279.000

Abstract

One of the health care facilities are hospital. Hospitals are required to provide quality services to give satisfaction to the patient. Services that are less than optimal will reduce the number of patients visiting. Therefore, improving the quality of service is needed in an effort to attract patients to seek treatment at the WiraHusadaKisaran General Hospital. This research was conducted by distributing 70 questionnaires and calculations were carried out using the Importance Performance Analysis (IPA) method and the Servqual method. The Servqual method is used to determine the level of patient satisfaction and the Importance Performance Analysis (IPA) method is used to determine which attributes need improvement. From the results of the calculation of the Servqual method using 5 dimensions of service, namely tangible, reliability, responsiveness, assurance, and empathy to determine the value of GAP. On the tangible dimensions of the attributes that have not satisfied the patient, the comfort and cleanliness of the hospital and inpatient environment. In the dimension of reliability attributes that have not satisfied the patient, the doctor conducts an examination of the patient according to the specified schedule and on time. In the dimension of responsiveness attributes that have not satisfied patients, namely, nurses quickly and responsively serve patients. On the assurance dimension has satisfied patients. In the dimension of emphaty attributes that have not satisfied the patient, namely, medical personnel respond to patient complaints. From the results of the calculation of the Importance Performance Analysis (IPA) method, it has a suitability level value of 79.34% and in the Cartesian diagram of the 20 attributes there are 6 attributes that require repair and improvement, namely attribute numbers 1, 3, 4, 8, 9, and 12.

Abstract

Education is an attempt by the Government to increase the country's potential to be able to compete with other countries that are experiencing very rapid development. The development of education will have an influence on the life of the local community, that is, it can affect various aspects of life, be it social, economic, cultural, religious, language and also the environment. The extent of the influence of educational development on aspects of life can be studied independently. Besides that, education also plays a major role in expanding employment opportunities, encouraging activities of supporting industries, introducing natural and cultural beauty that is inseparable from a sense of increasing brotherhood in the national and international environment. This is because education itself creates multiple economic impacts, namely direct, indirect, and secondary impacts, which provide opportunities for the growth of businesses and the role of local communities in the education sector. This research will discuss about Active Learning Training with Mathematics Tools at SDS HKBP Pembangunan 3 Medan. The result achieved is that schools are able to provide effective services online in the face of changing times caused by Covid-19 and can provide more information regarding the location of tourist objects that will be traversed by local and foreign tourists.
