Abstrak: Scheduling of Goods Distribution using a vehicle and a driver is a problem often faced by a particular company or business entity. Rest periods and working hours of drivers, as well as the time window established by the customer would affect the duration of distribution. Therefore, scheduling the distribution needs to be done in order to minimize the duration of distribution and also to get adequate rest periods for the driver. This problem can be modeled as a mixed integer programming. The objective of this paper is to model the distribution of goods scheduling problem by considering rest periods for the driver with the objective function is to minimize the duration of distribution. This model is implemented to distribution of animal feed in Payakumbuh by considering rest periods and working hours established by Indonesian government. This problem is completed by using LINGO 11.0 to obtain the distribution schedule with a minimum duration of distribution.

Judul: Masalah Pendistribusian Barang menggunakan Pemrograman Linear Integer
Abstrak: One of the important things in determining the distribution of products is searching distribution scenario that minimizes the total travel time from the depot to distributors, where the problem can be modeled as an Integer Linear Programming (ILP). In this work, we implemented the model to a candy company, where we had to deliver products to 5 distributors within 12 periods. Constraints should be considered are distributor inventory level, warehouse capacity, demand-supply balance, expiration date of product, and the maximum duration of each period of delivery. We here assumed that the delivery process to distributors is conducted through a predetermined order. The output of this model includes the retour trip between depot and distributors as well as the delivered amount of products in each period.

Judul: Studi Kasus: Patomorfologi Trakheobronkhitis Supurativa Pada Kucing (Felis Catus).
Abstrak: Trakheobronkhitis merupakan penyakit saluran respirasi yang sering terjadi pada hewan kecil, terutama anjing dan kucing. Penelitian berupa studi kasus ini bertujuan untuk mempelajari patomorfologi trakheobronkhitis supurativa pada kucing. Perubahan patologi anatomi berupa eksudat purulen pada lumen trakhea dan warna paru-paru yang tidak homogen, warna lebih gelap pada salah satu lobus, dan permukaan paru-paru lebih menonjol. Perubahan histopatologi berupa badan inklusi amfofilik-eosinofilik intranuklear yang dikelilingi oleh clear halo dan titik-titik kromatin ditepinya pada epitel kelenjar trakhea dan epitel bronkhiolus. Badan inklusi ini merupakan ciri dari FHV-1 dan adenovirus. Pada trakhea juga ditemukan koloni bakteri berbentuk coccobacillus sebagai infeksi sekunder. Bakteri tersebut diduga Bordetella sp. yang sering menginfeksi saluran respirasi kucing. Deskuamasi terjadi pada epitel trakhea dan bronkhiolus. Selain itu, ditemukan juga sel radang limfosit, makrofag, sel plasma, dan neutrofil. Pada paru-paru ditemukan lesio bronkhiolitis. Ditemukan juga bronkhopneumonia yang ditandai infiltrasi sel radang neutrofil dan sel nekrosis pada lumen bronkhiolus. Paru-paru juga mengalami emfisema dan edema pulmonum. Hiperemia dan hemoragi juga ditemukan pada kapiler paru-paru. Pada kasus ini, trakheobronkhitis supurativa diduga disebabkan oleh FHV-1, adenovirus, dan bakteri jenis Bordetella sp.
