Abstract

Kombinatorial bilangan Euler ialah suatu proses yang menghitung banyaknya alternatif permutasi dari himpunan bilangan dengan jumlah genap. Interpretasi kombinatorial bilangan Euler membutuhkan pemahaman dasar mengenai penurunan (descent) dan kenaikan (ascent) dalam permutasi. Beberapa artikel dan buku membahas tentang bilangan Euler, kombinatorial bilangan Euler, barisan bilangan Euler, bentuk umum bilangan Euler dengan berbagai metode. Dalam penelitian ini akan membahas lebih lanjut bagaimana bentuk umum interpretasi kombinatorial bilangan Euler yang didefinisikan pada progres aritmatika umum {a, a + d, a + 2d, …} kemudian membentuk algoritmanya.

Abstract

Uji homogenitas adalah prosedur uji statistik yang bertujuan untuk menunjukkan bahwa dua atau lebih kelompok sampel data diambil dari populasi yang memiliki varians yang sama. Jenis penelitian ini adalah penelitian kualitatif. Dalam penelitian kualitatif, peneliti tidak terjun langsung ke lapangan untuk mencari sumber data penelitian. Salah satu penelitian yang termasuk dalam penelitian kualitatif adalah penelitian kepustakaan. Pengujian persyaratan analitik merupakan konsep dasar untuk menentukan statistik uji mana yang diperlukan, apakah pengujian tersebut menggunakan statistik parametrik atau non parametrik. Uji syarat, yaitu uji homogenitas varians populasi dalam sebaran data penelitian. Uji homogenitas menggunakan statistik uji F, uji Bartlett, uji Levene, uji Cohran, dan uji Harley. Kesimpulan dari penelitian ini adalah betapa pentingnya pengujian syarat analisis ini, penulis menyarankan kepada peneliti untuk memperhatikan pengujian syarat analisis terlebih dahulu sebelum melakukan pengujian hipotesis, sehingga pengujian hipotesis yang kami ajukan adalah sesuai dengan uji statistik inferensial yang kita butuhkan dalam mengolah data hasil. belajar.

Abstract

The theory of opportunity arises from human activity which inspires bettors who try to find information on the chances of winning bets. Scientists who also like to play bets, experts make the theory of probability as a basic study of statistics and conduct mathematical analysis from a review of game examples. In this case, examine the toss of coins. To determine the probability of an event occurring in a coin toss, first calculate the number of sample points using the formula 2n where n is the number of sample spaces. In this case, the concept of the binomial theorem is used to determine the probability of an event occurring in the toss of a coin. The binomial theorem is very helpful in determining the probability of an event. Because it is very easy to determine the probability of an event is very rarely done.

Abstract

Pembelajaran matematika selalu berkembang seiring dengan perubahan kurikulum matematika sekolah. Pembelajaran matematika sekolah pada masa lalu yang mengadopsi kurikulum tradisional adalah pembelajaran yang berpusat pada guru. Pembelajaran matematika sekarang disesuaikan dengan kurikulum matematika sekolah sekarang yaitu kurikulum 2013 dengan pendekatan saintific. Trend pembelajaran matematika sekolah pada masa depan juga masih menggunakan kurikulum 2013 dengan pendekatan saintific dengan fokus utama adalah menciptakan siswa yang memiliki kemampuan matematis tingkat tinggi sehingga dapat berkompetisi secara global.

Abstract

The aim of this research, based on the problem formulation above, is to find out that inventory management by using the Ecolnolmic Order Quantity (EOQ) met mode can minimize the total inventory costs UMKM Home Industry Rumah Tempe Asli HB Pematangsiantar. This thesis research uses a quantitative descriptive method. The method used in controlling tempe goods inventory is the EOQ method. The EOQ method is a inventory management technique carried out by the company by determining the most efficient inventory amount of goods and producing balanced processing costs and storage costs, so that The company can minimize inventory costs. From the results of research using the EOQ method, the total inventory carried out with the EOQ metdown is 80.179 pcs with a purchase frequency of 22 times. The amount of security stock required by UMKM Home Industry Rumah Tempe Asli HB Pematangsiantar is 8.200 pcs. Total inventory using the EOQ method is IDR Rp1.122.421. EOQ meting can reduce the costs of providing merchandise more or can be said to be efficient if applied to UMKM Home Industry Rumah Tempe Asli HB Pematangsiantar. In other words, the inventory control carried out by the company is still not yet optimal. By using the EOlQ met mode in managing mobile inventory, Rumah Tempe Asli HB can optimize the cost of mobile inventory.

Abstract

Inventory is one of the most important things in a company, especially in the hospital industry, in providing drug supplies in order to provide good services. So inventory contro is needed to avoid running out and excess stock of drugs. The aim of this research is to find out the grouping of drugs based on their investment value, find out the optimum order quantity for each drug and find out the time to order each drug. The research method used by researchers uses quantitative methods, ABC, EOQ and ROP analysis methods. This research was conducted at RSUD Dr. Djasamen Saragih Pematangsiantar. From the research resuts, the ABC analysis method shows that 14 types of group A drugs (23.3%) use a budget of 69% of the total drug budget usage, 13 types of group B drugs (21.7%) use a budget of 22%. Of the total use of the drug budget and types of group C drugs, 33 types (55%) use a budget of 9% of the total drug budget use. By analyzing the Economic Order Quantity (EOQ) method, the optimum number of drugs was obtained for group A from 31-2,651 items, group B starting from 6-2,438 items and group C starting from 8-5,527 items. Meanwhile, with ROP analysis, the drugs reordered for group A range from 16-851 items, group B starts from 1-398 items and group C starts from 1-819 items.

Abstract

In the preparation of production planning, the goal to be achieved is not only one. Roti Sultan Meriah is a small and medium enterprise engaged in the production of bread. Roti Sultan Meriah aims to meet market demand and must also consider the costs used during the production process so that the profit obtained is maximized. In this study, the solution to the problem was solved by using the application of the goal programming method where this method can solve more than one goal, unlike in linear programming. The goal programming method used is a model with goal priority. The goal programming method with goal priority allows Roti Sultan Meriah to optimize various aspects of production simultaneously, such as meeting market demand, minimizing costs, and maximizing profits. This approach allows the company to prioritize these goals, so that it can make better decisions in production planning. By using this method, Roti Sultan Meriah can increase its operational efficiency and competitiveness in the competitive bread market. The results of this study obtained an optimal solution, namely the achievement of the sales volume target, production costs that do not exceed the target limit of Rp. 27,511,230, - and the profit target is achieved, namely Rp. 98,764,373, - for a period of one year

Abstract

Olimpiade Sains Nasional merupakan ajang lomba yang difasilitasi oleh tingkat kabupaten/kota, tingkat provinsi maupun nasional. Oleh karena itu setiap sekolah perlu membekali siswa-siswi nya dalam ajang tersebut. Dalam hal membekali siswa-siswi mengikuti lomba tersebut maka perlu persiapan yang matang yaitu dengan melakukan pelatihan Olimpiade Sains nasional (OSN) khusus nya bidang matematika. Setelah melakukan pelatihan olimpiade sains nasional, ternyata masih banyak siswa yang masih belum mengerti apa itu olimpiade sains nasional khususnya bidang matematika dan belum pernah mempelajari sama sekali soal-soal OSN bidang matematika. Akibat dari permasalahan tersebut maka perlu diadakan pelatihan-pelatihan Olimpiade Sains Nasional khusus nya Bidang matematika, setiap guru yang mengajar di kelas tersebut agar memberikan soal tambahan yaitu soal-soal Olimpiade Sains Nasional bidang matematika yang mana tingkatan nya mulai dari tingkat kabupaten/kota, tingkat provinsi dan tingkat nasional dan bahkan tingkat internasional serta setiap guru harus memberikan kunci jawaban nya. Kata Kunci: Olimpiade Sains Nasional, Bidang Matematika.
