ABSTRACTNewsboy problems is the problem of maximizing profits on products that have a time limit of sales and uncertain demand. This skripsi discuss multi-product newsboy problem with limited storage capacity. To deal with possible shortage of the product due to the limited storage capacity, the seller buy products outside the main agent called outsourcer. This newsboy problems can be modeled into a nonlinear programming problem. Next will be explained the properties of the optimal solution of this problem to obtain the optimal solution.;Newsboy problems is the problem of maximizing profits on products that have a time limit of sales and uncertain demand.

"Pada penelitian ini mengusulkan sebuah model matematik untuk menyelesaikan permasalahan Vehicle Routing Problem with Simultaneous Pickup and Delivery yang dikombinasikan dengan distribusi barang multiple product. Dalam hal ini kendaraan membawa mengangkut berbagai macam produk yang menggunakan kompartemen untuk tiap jenis produk. Berbeda dengan penelitian VRPPD, keunikan karakteristik pada penelitian ini adalah dalam penentuan rute kunjungan kendaraan tidak hanya dibatasi oleh kapasitas kendaraan namun juga dibatasi oleh kapasitas kompartemen dari tiap jenis produk. Dalam penelitian ini, perhitungan data set menggunakan metode pengelompokan berdasarkan net demand yaitu Smallest Maximum Load (SML) dan Largest Maximum Load (LML). Penentuan solusi tebaik didapat dengan menggunakan perhitungan algoritma Tabu Search.

This study addresses a method to solve Vehicle Routing Problem with Simultaneous Pickup and Delivery (VRPSPD) which combines a variety of products carried in a vehicle (multiple product). It examines the carriage with multiple compartment where each compartment is dedicated to a single type of product. Different from another widely studied pick up and delivery problems, the unique characteristics of this study is the route determination of the vehicle from the depot to customers because not only does it consider the vehicle's capacity but also the compartment capacity of each product as a limitation We calculate the set of instances using the customer grouping method (Smallest Maximum Load and Largest Maximum Load). The Solution obtained by the cheapest insertion method can be improved by Tabu Search algorithm. Finally, computational result are reported from test instance."

"ABSTRAKPeristiwa putus cinta dapat memunculkan perasaan kehilangan dan grief, menurunkan self esteem, menimbulkan distress, memunculkan perilaku maladaptif, gangguan fisik, hingga gejala depresi seperti misalnya melakukan usaha-usaha melukai diri sendiri. Hal tersebut dapat terjadi ketika seseorang mempunyai coping yang maladaptif dalam menghadapi situasi yang menimbulkan stres. Oleh sebab itu, diperlukan sebuah terapi untuk mengatasinya. Problem Solving Therapy (PST) merupakan sebuah intervensi kognitif perilaku (CBT) yang berfokus pada melatih sikap dan kemampuan pemecahan masalah yang adaptif. Tujuan terapi ini adalah membantu individu untuk dapat melakukan coping dengan lebih efektif pada situasi atau masalah yang dapat menimbulkan stres dan menurunkan tingkat stres. Penelitian ini menggunakan desain jenis one-group pre-test and post-test design. Pada desain penelitian ini, akan dilakukan pengukuran kepada setiap individu dalam kumpulan partisipan sebelum dan sesudah mengikuti intervensi yang diberikan, dengan menggunakan Beck Depression Inventory (BDI) dan Problem Solving Test. Partisipan yang didapat berjumlah 2 orang wanita berusia 23 dan 27 tahun. Intervensi PST dilakukan sebanyak 4 sesi. Problem Solving Therapy efektif dalam memunculkan coping yang adaptif pada kondisi putus cinta. sehingga pada akhirnya menurunkan tingkat stres pada dewasa muda paska putus cinta.

ABSTRACTBreakup can cause grief, distress, lowered self esteem, maladaptive behavior, physical disturbance and depression such self-destructive behavior. When there is no adaptive capability to solve breakups, it can worst its effect. Therefore, it will need to be solved immediately. Problem Solving Therapy (PST) is one of Cogntive Behavior Therapy that focused on training the individual to have adaptive problem solving skill. PST can train the coping skill and minimize the level of stress. This research uses one group pre-and-post test design non-experimental. This research also use Beck Depression Inventory and Problem Solving Test as an instrument to measure the therapeutic effect before and after the intervention. There are two female participants had joined this research. They are 23 and 27 years old. The intervention held in 4 sessions. In conclusion, PST is effective to improve adaptive coping style and reduce stress for female young adulthood on breakup."

"Cross-docking memberikan berbagai keuntungan dalam logistik, seperti kecepatan bongkar muat, konsolidasi, dan pemindahan barang ke kendaraan pengiriman. Vehicle routing problem dengan cross-docking (VRPCD) merupakan perkembangan dari vehicle routing problem dengan fungsi batasan tambahan, dimana depot memiliki peran sebagai cross-dock. Penelitian ini mengusulkan model linear mixed-integer untuk VRPCD yang memperhatikan faktor-faktor multi-produk, multi-kendaraan, split load, dan multi-periode. Sebuah dataset dibangkitkan berdasarkan literatur. Dataset tersebut terbagi menjadi dua, yang menggunakan kendaraan homogen, dan yang menggunakan kendaraan heterogen. Data tersebut diselesaikan mengunakan solver Gurobi. Hasil menunjukkan bahwa kendaraan heterogen memiliki solusi lebih baik namun membutuhkan waktu komputasi tambahan. Split load dapat menghasilkan nilai yang lebih baik dan mendapatkan solusi yang sebelumnya tidak mungkin. Pengiriman multi-periode memberikan potensi untuk menurunkan waktu pengiriman jika fungsi tujuan menjadi meminimumkan waktu pengiriman maksimum. Hasil komputasi juga menunjukkan bahwa dataset lebih kecil (10 node) dapat ditemukan hasil optimal dalam waktu yang relatif singkat.

Cross-docking provides benefits such as facilitating fast and direct unloading, consolidation, and reloading of goods from inbound to outbound trucks. The vehicle routing problem with cross-docking (VRPCD) is an extension of the vehicle routing problem with an additional constraint in which the depot has a role as cross-dock. The current paper provides a mixed-integer linear programming model for the VRPCD that considers multiple products, multiple vehicle types, split loads, and multiple period delivery. Based on the literature, we generated two sets of instances, one with a homogenous vehicle and one with heterogeneous vehicles. The instances are then solved using the Gurobi Solver. Results show that instances with heterogeneous vehicles provide better results but require an increase in computation time. Split loads can produce better objective values and generate solutions previously infeasible. Multiple-period delivery has the potential to decrease delivery times if the objective function is set to minimize the maximum time. The computational results also show that smaller instances of 10 nodes can be solved in a reasonable amount of time"

"Mathematics educators agree that problem solving is one of the essential skills their students should possess, yet few mathematics courses or textbooks are devoted entirely to developing this skill. Supported by narrative, examples, and exercises, Ants, Bikes, and Clocks: Problem Solving for Undergraduates is a readable and enjoyable text designed to strengthen the problem-solving skills of undergraduate students. The book, which provides hundreds of mathematical problems, gives special emphasis to problems in context, often called story problems or modeling problems, that require mathematical formulation as a preliminary step. Both analytical and computational approaches, as well as the interplay between them, are included.With its lively and engaging writing style and interesting and entertaining problems, Ants, Bikes, and Clocks will strengthen students� mathematical skills, introduce them to new mathematical ideas, demonstrate for them the connectedness of mathematics, and improve both their analytical and computational problem solving. One of the remarkable and unusual features of this text is that it encourages students to use the computer for experimentation. In fact, Briggs uses a variety of tricks that encourage students to use any tool at hand to test their ideas."
