Transportation is an activity to move goods or people from one place to another. At present, transportation is very much needed by all groups to carry out an activity. Along with the development of the times and with the development of the times and with the existence of an internet, now many enterpreneurs are opening a business such as online transportation. This study uses the Fuzzy Time Series Cheng method in his research to see how accurate the model is to predict the future period. The results of the research using the Fuzzy Time Series Cheng method on the five service features in the Oke Jack, it was found that some of these service features resulted in MAPE error values below 10%, which is the best measure.

Every company that carries out businees activities generally has inventory. Inventories include raw materials, semi-finished goods or finished goods. Inventories of goods in the company have increased and decreased. An increase in inventory can cause losses, because the cost of storing and maintaining in the warehouse is too high. While a decrease in inventory can result in a shortage of inventory. The purpose of this research is to determine the level of optimal inventory in PT. Industry Plywood Tjipta Rimba Djaja. Using the optimal control theory model and analyzing the stability of the dynamic differential equation, to find the optimal inventory level. Obtained optimal inventory levels achieve stability at the time . For the planning length of 12 months includes: raw material inventory (logs sengon and rambung), production (finished materials in process) and finished plywood or plywood products that are in the warehouse. From this research optimal control theory can be applied in PT. Industry Plywood Tjipta Rimba Djaja to optimize inventory on the problem of increasing inventory.

Interest is an internal component within an individual that greatly influences his actions. Education is the process of changing the attitudes and behavior of a person or group in an effort to mature a person through teaching or training. The aim of this research is to determine the factors that influence high school students' interest in continuing their education to higher education using the latent class regression analysis method. The latent class regression analysis method can determine the influence of accompanying variables or covariates in the formation of latent classes. The most dominant factors influencing high school students' interest in continuing their education to higher education are needs, facilities and attention. In the first class the influencing factor is need. In the second and third classes the influencing factor is facilities. In the fourth class the influencing factor is attention.

Ikan mas koki (Carrasius auratus) adalah ikan memiliki ciri khas yang tersendiri. Keunikan dan keragamannya dapat diukur dari warna yang cemerlang, bentuk dan kelengkapan fisik. Tujuan penelitian ini adalah untuk mengetahui primer yang efektif, polimorfik genetik DNA dan kekerabatan pada Carrasius auratus yang terdapat di pembudidayaan ikan hias, Binjai Utara dengan menggunakan metode RAPD dengar enam primer yaitu OPA 13, UBC 101, UBC 456, OPD 20, OPA 02 dan OPC 02. Tahapan yang dilakukan pada penelitian ini diantaranya isolasi DNA menggunakan Kit Favorgen, amplifikasi PCR, dan elektroforesis. Hasil penelitian menunjukkan primer yang teramplifikasi dan menghasilkan pita polimorfik adalah primer OPA 13, OPA 02 dan OPD 20. Jumlah pola pita dari hasil amplifikasi primer tersebut sebanyak 32 pita dengan panjang basa yang berkisar antara 100 bp – 1500 bp. Pita yang muncul kemudian diterjemahkan kedalam data biner dan dianalisis dengan program NTSYS versi 2.02. Menunjukkan bahwa kekerabatan terdekat adalah pada ikan mas koki jenis Ryukin dan Oranda dengan memiliki koefisien 0,74 atau sebesar 74%, sedangkan kekerabatan jauh pada Ikan Mas Koki Rachu dan Teleskop dengan koefisien sebesar 0,75 atau sebesar 75%. Dari data hasil panjang pita 900 bp, 600 bp, 400 bp, 300 bp 200 bp dan 100 bp dari komponen pertama memiliki peran penting dalam pengelompokkan Carrasius auratus dalam dendogram.

The aim of this research is to seek optimization of rice planting costs using the method Kuhn Tucker. The method used in this research is method Kuhn Tucker. Method Kuhn Tucker is a method used to find the optimum point of a function without having to look at its linear or nonlinear properties. The solution to this method is to substitute it into the method Lagrange and must be given sufficient conditions Kuhn Tucker. Research results with methods Kuhn Tucker The Laswan Rice Refinery gets optimization of used costs with 24.96 Kg, 6.24 sacks of fertilizer, 3.7 Kg of pesticide and 1.3 HOK wages, so the optimal cost used is Rp. 11.875.370.00,- a hectare.Key Words: Kuhn Tucker Method, Lagrange Method, Optimization, Cost, Rice
