Judul: Rancang Bangun Sistem Bisnis Berbasis Internet (E-Business) Untuk Agroindustri Kulit Samak (Leather)
Abstrak: Trading business based on information technology in the recent years is expected to dominate the world. In Indonesia, information technology-based business has not been used optimally. Opportunities in the utilization of online transaction is actually widely open. One of the potential commodity to develop and to commerce is the leather. This research aims to design a web based business systems (e-business) for leather commodity, through developing an online transaction system (e-commerce) and customer services. Scope of this research was a system designed internet business system for leather commodities that include to informing products, sale and purchase transactions, customer service and cooperation with business partners in the form of exchange data and information. The data of product specifications and prices were obtained from five companies. There were 124 kinds of products to sale. This website was built by using Macromedia Dreamweaver, Adobe Photoshop CS3, Photoscape and mySQL database, such as seven main menus on the homepage of the website, which can be accessed by the customer, i.e : Home, Product (Finished Leather, Finished Product), Customer Account (Registration new customer, Login customer, and Logout customer), Contact, Supplier and Other Industries (Chemical and Machinery Suppliers and Other Leather Industries), Payment and Delivery (Leather Product Purchase Guide and Payment Method and Delivery Cost) and Customer Services (Discussion Forum and Order Status). Meanwhile, the duty of administrators was updating the menu of products, shipping and order status, check transactions, and calculating the profit/loss per month per product item and also drawing graphic information in sales per year. The mechanism of E-CLT payment was interbank transfer facility. The payment was validated by sending the proof of payment slip to the customer by email.

Judul: Prototipe Rancang Bangun Sistem Informasi dan Komunikasi Online Usaha Kecil Menengah (UKM) Agroindustri Berbasis Web.
Abstrak: Small and medium agroindustrial enterprises had a potential role in national economic development. The purpose of this research was to design a system of information and online communication that could provide people on gaining information about small and medium agroindustrial enterprises. The information systems called AGROIND v.1.0 provided information on raw materials, products, technology selection, cost of investment, benefit and cost analysis, feasibility study, online communication, and some additional information about small and medium agroindustrial enterprises. This research used system approach, consist of needs analysis, problem formulation, system identification, and modeling verification. Oyster mushroom and mushroom crackers industry data were used for model verification. The results of financial analysis showed that NPV was Rp264 126 863, payback period was 2.82-year, and benefit cost ratio was 1.63. AGROIND v.1.0 should be developed for other agro-processed commodities and products by added other validated data.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
