Abstract

The objective of the research is to find out whether the extract of kelor(Moringa oleifera) leaves can be used as antibacteria of decomposer bacteria (Pseudomonasaeruginosa) in fresh fish and to find out the most effective concentration ofkelor extract as antibacteria. The research starts with making the extract of kelor(Moringa oleifera) leaves by using maceration technique. The next step is makingNatrium Agar (NA) as the medium for growing the bacteria and the third step istesting the extract of kelor (Moringa oleifera) leaves on the bacteria (Pseudomonasaeruginosa) by using the aseptic technique and streak plate method. The bacteriawere incubated for approximately 24 hours in the room temperature. Next, thediameter of the clearzone produced in each treatment is measured. In this researchthere are five variations of kelor leaf extract concentrations, namely 0%, 25 %, 50%,75%, and 100% with five repetitions. Based on the SPSS analysis using Anava testing,the significance level is 0.007 ≥ 0.005. It shows those five treatments of giving theextract of kelor leaves with the concentrations of 0%, 25%, 50%, 75%, and 100% donot significantly affectthe activities of Pseudomonas aeruginosa bacteria. Based on theresult of the observation, the average length of the diameter of clear zone on theextract concentration of 50% is the biggest, which is 1 mm long. Thus, it can be concludedthat the extract of kelor (Moringa oleifera) leaves can be used as antibacteriafor the decomposer (Pseudomonas aeruginosa) bacteria of fresh fish.

Abstract

Decision makers need analytical tools that allow them to solve problems. Decisions to be taken are complex with major risks such as policy formulation, decision makers often need tools in scientific, logical, and structured forms. To determine the priority stages of criteria in order to obtain the most optimal results in returning uniform vendor selection decisions at PT Penjalindo Nusantara (Metaform) using the AHP (Analytical Hierarchy Process) method. In essence, AHP is a comprehensive decision-making model by taking into account qualitative and quantitative matters. There are three main principles in problem solving in AHP, namely: Decomposition, Comparative Judgment, and Logical Concistency. Bycomparing in pairs to determine the priority weight on each criterion and alternative. One of the paired comparisons is carried out in pairwise comparisons between criteria. Vendor selection criteria include quality, price, flexibility, delivery and service criteria. . Compiling alternatives that have been determined in the form of matirx in order to obtain the assessment weight of each variable, a table of pair comparison rating scales is made. Based on the results of the AHP calculation, each weight for each venodr is obtained PT Intan of 0.62860 and the weight value of the Super Decision is 0.638683. PT Parahita as a vendor with a weight value of 0.20475 and a weight value in Super Decision of 0.203985. PT Marcapada with a weight value of 0.16665 and a weight value in Super Decision of 0.159189. So the main uniform supplier is PT Intan with the largest weight.
