Nine companies in the Washington-Baltimore region are listed this year in Black Enterprise magazine's survey of the largest 100 black-owned firms in the nation.

In addition, two Washington-area companies made sharp jumps on the list, published in the magazine's June edition. Sterling Systems Inc., a McLean-based computer services company, jumped into the 37th spot on the list with 1980 sales of about $12.5 million.

Systems & Applied Sciences of Riverdale, Md., had the fifth-sharpest sales increase of any of the companies on the survey, showing a 132 percent rise in 1980 revenues compared with the previous year. The company's sales rose from $5.7 million to $13.2 million over the one-year period, Black Enterprise said.

In addition, United National Bank of Washington ranked fifth on the magazine's list of the largest black-owned banks in the nation and Industrial Bank of Washington ranked sixth. Washington's Independent Federal Savings & Loan Association was cited as the sixth-largest institution of its kind in the nation.

The nation's largest black-owned firms showed a 23.3 percent rise in revenues in 1980, jumping from sales of $1.24 billion in 1979 to $1.53 billion in 1980. For the ninth consecutive year, as long as the survey has been assembled, Motown Industries, the Los Angeles-based music company, maintained the top spot on the list, this time with sales of $91.7 million.

In the nationwide survey, perhaps the most startling figure is the jump reported in the sales of Wallace & Wallace Enterprises Inc., a fuel-oil company based in St. Albans, N.Y. During the past year, the company's sales rose from $25.9 million to $81.9 million, moving the company up in the Black Enterprise survey from the 10th to the No. 2 spot on the top 100, as John Publishing Co. Inc. dropped from No. 2 to No. 3.

But in this region, Jackson Oil Co., a Baltimore firm, rose from a 34 ranking to 18th with sales of $18.2 million, making the company the largest of this region's firms in the magazine's rankings. Jackson Oil is followed closely on the list by Community Foods Inc., a Baltimore supermarket concern, in the 19th spot. The largest company from the Washington area is Misso Services Corp. & Associates of Falls Church, which fell in the survey from the 15th position to the 24th.

Other area firms in the ranking of industrial companies include Blunt Enterprises, the District-based construction firm, which ranked 42 after being unranked last year. Blunt reported sales of $11.7 million in 1980.

In the 63rd position is McLaughlin Oldsmobile Inc. of Capitol Heights with sales of $7.7 million. Raven Systems and Research Inc. ranked 69th with sales of $7.5 million, up from the 95th position. Seidel Chevrolet of Landover ranked 98th with sales of $5.2 million, according to the survey.
