INTRODUCTION
Vocational High School (SMK) is a formal education unit that organizes vocational education in secondary education as a continuation of the SMP / MTs. Vocational School (SMK) has some expertise program which grouping students according to their interests, talents and abilities. Program membership is provided in each vocational the same, but each has a featured vocational skills program. Some of the programs contained in the vocational skills in Surakarta include membership program mechanical engineering, automotive engineering, network engineering, craft engineering, building engineering, office administration, hospitality, culinary, beauty and others. On each program membership, each producing goods or services associated with the programming expertise.
The production unit is an activity or effort in school that aims to empower the school's resources and carried out by the school community. The production unit is a container of entrepreneurship in products (goods) or businesses (services). The production unit developed in Surakarta vocational schools produces the product, but the effect is still little known by the public.
The use of conventional means of marketing merely involves communication between schools and the school community. Marketing is still a very limited lead product in the form of goods and services produced less known by the public. One solution to overcome this problem by doing marketing with the utilization of technology development. Online marketing is a form of direct marketing that is growing most rapidly. Online marketing is a venture company to market the products of services and building customer relationships through the Internet. (Kotler & Armstrong, 2008: 237). The website is one example that can support the use of technology in marketing products and services. Websites that are normally used in the marketing process is based on an e-commerce website. Jony Wong. (2010) suggest e-commerce is the buying, selling and online marketing of goods and services through electronic systems. In Sunarko research and Sukadi (2013), the design of e-commerce can help apply online store sales as well as promotional media solutions and information products offered to consumers. Research  Ariyani (2013) also states that the design eCommerce helps consumers make the transaction process. In studies, Cao and Yang (2016) concluded that the application of e-commerce on the website showed a better performance of the website This website is built using the PHP programming language and MySQL database. Kadir (2003) stated PHP is designed to form a dynamic web, meaning that it can create a view based on current demand. Nugroho (2005) revealed MySQL database server is a program that is able to receive and transmit data very fast, multiuser and using standard SQL (Structured Query Language).
Based on the above reasons can be based on eCommerce website development marketing for CMS production units. The construction of the marketing website is expected to help the management of the production units and introducing vocational school products to the general public.

METHOD
The method of this research is research and development (R & D) by Sugiyono. This study includes five stages: analysis of the potential and problems, data collection, product design, product validation and product revision. The research was conducted at a vocational high school entire Surakarta.
