Abstract

Bagasse is a byproduct of extraction (squeezing) of sugar cane. A single sugar mill can produces around 35-40% (weight) of bagasse from sugar cane milled. Bagasse which is a sugar cane mill waste can be processed into a fiber rope. Fiber rope can be made from many kind of tree bark, it makes the utilization of bagasse for a fiber rope is possible. The research was aimed to make a fiber rope from bagasse and to test the endurance of sugar cane fiber rope toward a tensile test.Results of the research indicated that each substance tested with the same weight produced different string diameter. Average value of examinatied 8 g streng had diameter of 5,83 mm, length of 58,3 mm, elongation of 22,66 mm, maximum loaded of 283,33 N, cross section of 2,489 x 10-5 m2, elongation at break of tensile strength of 105,6 x 105 N m-2, strain of 0,39, elasticity of 303,9 x 105 N m-2 and flexing of 38,7 %. Key Words: bagasse, fiber, rope, spun, tensile test.

Abstract

The RPM of coffee roaster mixer tool is needed to care. The machine RPM will affect the roasting quality. Various level of PRM were tested to know the quality of coffee produced. Research had been conducted at agricultural engineering laboratory, faculty Agricultural USU in July till October 2013 with using factorial randomized block design with one factor i.e 15, 25, 35, 45, and 55 revolution per minute. Parameters observed were organoleptic test, yield, process capacity and water content. The results showed that the RPM had highly significantly effect on the organoleptic test, yield, process capacity, and water content. Keywords:Ccoffee quality, coffee roaster machine, RPM test.

Abstract

Information System of Agricultural Land ( Rice) in Manduamas Sub District area was still done manually, so the storage, processing and delivery of information to be ineffective and inefficient. In the information management most the result were done by human role and took a relatively longer time. Moreover, the information seekers-and decision-makers also had difficulty in obtaining the data they need. Therefore, it is necessary to further develop of the information system. Web-based information system is considered to be a solution in order to access information faster, systematicaly and easy to use. For that a web-based information systems in the management of imformation system of agricultural land ( rice) in Manduamas sub district was designed. Agricultural land network information system was designed using PHP programming language, MySQL database and the method of system development life cycle (SDLC). The result was adynamic website that displays information and could interact with the user and was user friendly where the model user interface of the web was made to facilitate the user to use system properly. Keywords: Agricultural land, information system, Manduamas Sub district, rice, web.

Abstract

It is time for Indonesia to reduce dependence on using paper with tree raw materials. It can be an alternative environmentally friendly paper and does not increase the cut down of trees. The making of paper using the trunk of banana (Musa paradisiaca) and waste paper is suitable to overcome the problems of the use of the current paper. This research was done on May-Juni 2013. The paper making was done at Jl. Roso. No. 8 Delitua Medan North Sumatra and the testing of paper was done in PT PDM Indonesia, Laboratory Medan, using non-factorial randomized block design with one factor.i.e. waste paper composition (0%, 10%, 20%, 30%, 40% and 50%). Parameters observed were grammage, tensile and tearing strength. The results showed that the composition of the waste paper had highly signifficant effect on grammage and tensile strength. The resulting paper could be categorized as art paper with the best result of grammage was at the composition of 30% (350 g banana trunk and 150 g waste paper), and tensile strength and tearing strength at the composition of 0% (500 g banana trunk). Keywords: banana trunk, pulp composition, paper, waste paper

Abstract

On mechanical coffee roasters, roasting temperature needs to be considered. The temperature determines the quality of the roasting product. This study is testing the temperature at various levels of coffee roasters rotary tool on the yield and quality of coffee. The study was conducted at the Laboratory of Agricultural Engineering USU College of Agriculture in January to April 2013 using a non-factorial completely randomized design at 70 ⁰ C, 75 ⁰ C, 80 ⁰ C, 85 ⁰ C and 90 ⁰ C. Parameters measured were yield, processing capacity and water content. The results showed that the test temperature had highly significant effect on yield,had highly significant to the processing capacity, and had not significant affected the water content. The best treatment of this research is the treatment T3 (80⁰C) which produced 81.2% yield, processing capacity of 3,252 kg / hour, and the water content of 5.948% Keywords: Coffee roaster, Coffee quality, Temperature test
