Abstract

Diazinon is an organophosphate pesticide used by farmers in increasing agricultural production because its ability to control various pests. Excessive diazinon has potential as a pollutant in the environment. It residues are not soluble in water and difficult degraded. Also diazinon is toxic. This is a fatal effect on non targets body. This research aims to study and test the growth ability Pseudomonas putida strain 071 in medium containing 0.5% diazinon substrate. This study begins with the purification of Pseudomonas putida strain 071 isolates with scratch techniques. The growth ability tested through growth experiments using liquid basal medium containing 0.5% diazinon. Each interval of time, the growth observed using spectrophotometry (A = 620nm).The results obtained that the Pseudomonas putida 071 were able to grow in liquid basal medium containing diazinon. The splitting speed containing diazinon is 0.197 and 0,187 without diazinon. Generation time of Pseudomonas putida 071 use diazinon 5.2 hours and 5.4 hours without diazinon. Pseudomonas putida 071 that grow in liquid basal medium containing diazinon showed that diazinon residues can be used by this bacteria as a growth substrate. This bacteria has potential as pesticide degrading agents that can be used as a biopesticide active ingredients.Key words: Diazinon, Pesticide, Pseudomonas putida.

The aims of this research are determine differences influnce the concentration of adhesive to the combustion heating value and detremine the optimum heating value. The method is performed in this study is an experimental method. Data obtained from the analysis with use a bomb calorimeter, which is at a concentration of 10% adhesive produced calorific value 4100.350 cal/g, 20% of the calorific value of 3674,14 cal/g, 30% of the calorific value of 3689,52 cal/g, 40% of the calorific value of 3902,21 cal/g and at a concentration of 50% adhesive calorific value generated is 3959,02 cal/g. The results of statiscal analysis using the inferential Analysis of Variance (ANAVA), with F test, F arichimetic (0,168) < F table (5,19) at significant level α = 0,05 then H0 rejected it means tha there is no difference in the influence of the concentration of adhesive to the calorific value biobriquet burning corn stalks on.Key words: Corn Stalk, biobriquet, calorific of combustion.

Abstract

Semantic Web is a set of technologies, which allows the computer to understand the meaning of information based on metadata, which is information about information. The semantic web is a vision of Tim Berners-Lee to make the web a meaningful resource data. This can be realized by using the infrastructure that is defined by the working group at the W3C (World Wide Web Consortium), the Resource Description Framework (RDF). RDF consists of three compositions, namely the subject, predicate and object. Subject and object is an entity which is indicated by the text. While the title is a composition that explains the point of view that will be the subject described by other objects. So that the object or entries can be clearly explained and detailed, and in accordance with the wishes of users who give feedback. College libraries generally have to manage a collection of local (institutional repository) each such book, thesis, journals, research reports produced academic faculty. No exception in the Public Library of UIN Alauddin Makassar. However, from the observation of the researcher, the dissemination of information regarding the collection at the library not optimally managed, so that can lead to delays in the distribution of information regarding the collection to the public library. Implementing a searching tool that implement semantic web technology for the library, is one of solution that can be use to overcome such problem.Keyword: Semantic web, Resource Description Framework, library, web searching, semantic searching

Abstract

The aim of this research to investigate the quality of coconut oil and palm oil through its measurement of the wavelength spectrum. Spektrofotomer is used to measure the wavelength spectrum, before and after used.The samples are fresh oil, and expired oil. Analysis of the quality of coconut and  palm oil based on wavelength spectrum show that caconut oil oil is better than palm oil. Analysis of the quality of coconut oil and palm oil show that  palm oil to sample use of coconut oil not containing compounds melanoidin while palm oil for one used melanoidin containing compounds have been found in wavelength of 540 nm which is a green area.Keywords: quality,oil, spectrophotometer.

Abstract

Graph theory is a part of mathematics, in which there are explanations of digraphs. This research, purposed to show a table based on Cayley digraphs depiction dihedral group. A digraph can be described from a group, one of which is the operation of the Cayley table of the dihedral group. Dihedral group is the group of the set of symmetries n-terms of regular, denoted D2n, for each positive integer n, n  3. This, the dihedral group will be divided into two subsets, namely:1. x = {1, r, ,... } or known with subsets rotation;2. v = {s, sr, ,...} or known with subsets reflection.Based on the analysis of this research showed that, to obtain a connected digraphs, the depiction of these digraphs, dihedral group can be formed on the element generator, generator (r, s), and the generator (s, sr) to form a composite image with elements digraphs elements x and y. on the operation of the Cayley table dihedral group, which contained depictions digrap shekel same cannot be combined. From the results of the operation of the rotation and reflection on the dihedral group D6 Cayley table which is a group of abstract forms, latin squares, which can be described by a digraph elements of the generator it.Keyword: Eulerian digraph, Hamilton digraph, Cayley Table, Dihedral group, Reflection, Rotation.

Abstract

The aim of this study to determine the effect of feeding commercial rations on the final live weight, feed conversion and "income over feed and chick cost".This study uses 90 mixed sex chicken experiment with strain "Arbor acres" 707 SR. It produced of PT. Satwa Utama Raya (SUR), Maros and maintained for 6 weeks. They treatmented with 3 (three) rations : 1) Rx = feeding  rations manufactured by PT. X, 2) Ry = feeding rations manufactured by  PT. Y and 3) Rz = feeding rations manufactured by PT. Z. There are 5 (five) repetition for each treatment. The parameters are the final live weight, feed conversion and "income over feed and chick cost". The data are processed with a range of RAL and continued analysis of LSD when the results are significant.The result showed that the use of commercial rations are not significant to the final live weight, feed conversion and “income over feed and chick cost.

Abstract

The aim of this research was to study the performance of broiler given ratio containing powders of Souropus androgynous, turmeric tuber, and their combination. Sixty four broiler, day old chick (doc), were randomly assigned in to 16 experimental cages (4 broilers/cage) with the size of 100 cm x 50 cm x 60 cm/cage. The treatment were : T0 = based ration (control), T1 = based rastion + 1 % Suropus androgynus, T2 = based ration + 1 % turmeric tuber, and T3 = based ration + 0,5 % Sauropus androgynus + 0,5 % turmeric tuber.Statistical analysis indicated that addition powder of sauropus androgynus, turmeric tuber, and their combination into the broiler ration did not effect (P>0,05) performances of broiler (feed consumption, daily gain, carcass percentage, abdominal fat percentage, and feed convertion). Conclusion ; Treatment powder of Sauropus androgynus, turmeric tuber, and their combination give the same effect on performance (consumption, daily gain, carcass percentage, abdominal fat percentage, and feed convertion) broiler.Key word : broiler, sauropus andrygenus, turmeric, performanc
