Klebsiella pneumoniae is one of the most bacteria found in urine of Urinary Tract Infection (UTI) Patients. Study in many countries has found that this species become resistant to more than one antibiotics. This research goal is to know the effectiveness of talok (Muntingia calabura) infused water inhibiting the growth of K. pneumoniae. This was an experimental study using K. pneumoniae bacteria isolated from urine samples using diffuse agar method. The concentration of talok infused water was varied from 25-100% and the antibiotics used was cefotaxime, meropenem and chloramphenicol. The inhibition activity was measured by the diameter of inhibition zone. The results show that K. pneumoniae is still give sensitive response to antibiotic treatments. While the inhibition zone from talok infused water treatments can be categorized in middle and strong activity. From this study we can conclude that talok infused water potential in inhibiting the growth of K. pneumoniae. Future study still needed to develop this potential, especially for the bacteria that has been resistant to some antibiotics.

Newcastle disease (ND) is a contagious viral disease caused by Avian Paramyxovirus Serotype-1 (APMV-1). This viral infection is responsible for devastating outbreak by attacking nerve, respiration, and also digestive system. This disease often followed with decreasing of eggs production and also responsible for economic losses in the poultry industries around the globe. The main goal was to differentiate virulent or avirulent strain of ND virus from F gene, which is the virulent marker of ND virus, by Reverse Transcription Polymerase Chain Reaction (RT-PCR) and Restrion Enzyme Analysis using BamH1, Hin 1l, and Apa 1. Ten ND virus samples came from Animal Disease Investigation Center (ADIC) Wates virus collection, collected from field case in 2012-2013. Newcastle disease virus was collected by extraction from the samples. The RNA product of extraction were used as a template for amplification in RT-PCR. The target of RT-PCR amplification was F gene. The results indicated positive reaction due to existing of DNA fragment band in size of 767 bp. RT-PCR and Restrion Enzyme Analysis can be used as tool to determine the pathotype of ND virus showed different restriction visualized by gel agarose electrophoresis.

The brake blocks are components of the railway braking system that are useful for reducing speed or stopping the railway. In the development of railway brake block material needs a device that capable of testing the characteristics of the brake block material. One of the important characteristics of the brake block material is the frictional characteristic. The method of testing the frictional characteristics of existing brake blocks include using the pin on disc method, direct testing on the railway and using a full-scale dynamometer. The full-scale dynamometer has advantages than other methods because it can test specimens according to the actual railway braking conditions in a short time and less preparations. However, with the same specimen size as the original, the cost of making the specimen and the full-scale dynamometer become expensive. Therefore, to reduce the cost of making device and test specimens, this study will design the dynamometer small-scale brake block testing. This paper use Pahl and Beitz design method which divides the design into four stages: clarification of the task, conceptual design, embodiment design, and detail design. This dynamometer is designed by considering function designs, structures, and forces that are adapted to the brake block contact pressure according to the original conditions. This dynamometer is designed to vary material, wheel speed, and contact presssure with the output of measurement of friction coefficient of brake block material. Brake block test specimens have a reduced size with a 1: 4 scale from their original size. The results obtained from this research are engineering drawings and dynamometer test model of railway braking.

Wood is widely used for structural and non-structural purposes. In non-structural purpose, wood is used, among others, as furniture, parquet (wood floor), partitions and so on. In line with the decreasing availability of wood, the price of wood is becoming increasingly expensive. In certain uses, substitute materials such as particle boards have been started to use. Particle boards are generally composed of certain wood powder wastes. This study aimed to look for alternative materials for building particle boards from coconut shells. The particle boards to be tested were composed of coconut shells with the addition of certain wood powder which is added with certain percentage. Particle boards were printed with a certain size, given certain pressure and tested for their physical properties. The physical properties of the particle boards tested included particle density, water absorption, dry flexural modulus, and dry bending fracture modulus. The results showed that the best mixture composition capable of producing density values, water absorption, fracture modulus and optimum modulus of elasticity were found in the proportion of mixtures of 70-90% coconut shell particles and 30-10% wood particles.

As we understand together that today has begun to decrease the utilization of deep well water and water springs as an alternative source of water in the PDAM, this is due to environmental conditions that have undergone many changes so that our environment has been experiencing a lot of carrying capacity. The selection of deep well water is preferred because the water quality is relatively better than the surface water. This condition causes PDAM to choose surface water such as river water as raw water, such as Progo water which is now used as alternative water for PDAM Kota Yogyakarta, PDAM Sleman and Bantul. Characteristics of surface water are generally poorer than ground water, this is due to more possibilities of contamination with pollutants resulting from human activities such as industry, agriculture and even natural events such as rain. It is physically easy to see that the surface water is generally cloudy compared to groundwater, since surface water generally contains mud and larger suspended particles. To reduce the mud content and suspended particles can be used coagulant material. There are many types of coagulant materials that we know such as alum (Alumunium Sulfate, Sodium Aluminate, Ferro Sulphate, Ferric Sulphate, Ferric Chloride, Lime and others). Technically coagulant capable of decreasing turbidity up to 0 NTU is Al2(SO4)3, combination between NaAlO2 and PAC, and combination between Fe (SO4) and PAC. Economically the cheapest coagulant is alum, with the optimum dose not much different but the purchase price is much cheaper than other types of coagulant.

The objectives of the research are (1) to identify the infrastructure of green open space (RTH) concept on the road corridor, (2) to analyze the fulfillment of road space conditions against the requirements of road functional (SLFJ), (3) to analyze the completeness and condition of the road facilities to meet the green open space standard (SRTH), and (4) to set up development directives and design concepts for the management and maintenance of road space infrastructures that support green open space standards based on road functional requirements. Primary data for the analysis were obtained by direct observation/survey at the research site in Jalan Abu Bakar Ali, Malioboro, and Solo in Yogyakarta City and survey of respondents of road users with questionnaires. Secondary data used to support the analysis are (a) road map and condition of around study sites, (b) assumptions in design standards, (c) standards on markers, signs, lighting, drainage, and (d) related study reports. The method of quantitative and qualitative analysis according to SLFJ and SRTH was applied rationally. It can be concluded that the knowledge and perceptions of respondents about the use of road space and environmental conditions around the road in the three locations was obtained in Good category with scores of 3.4; 3.52; and 4.2, respectively. In Jalan Abu Bakar Ali respondents responded Agreed (score of 4.18), meaning that it required additional facilities and maintenance of the RTH’s facilities and landscape. The management and maintenance of RTH's infrastructure and facilities of Jalan Abu Bakar Ali, Jalan Malioboro and Jalan Solo has been done by Yogyakarta City Planning Agency, organized and well-scheduled. Based on the evaluation of road functional requirement in Jalan Abu Bakar Ali (secondary collector), Jalan Malioboro (secondary artery), and Jalan Solo (secondary artery), all that are categorized as Conditional Function (LS). It means that the road has not fulfilled some road functional requirements in terms of utilization of road space, or there are still technical recommendations that must be met so that roads can be categorized as Function (LF). It obtained that Road Use Space (RUMAJA) is not effectively used, which characterized by still many permanent and non permanent buildings in the RUMAJA area. The design concept of the management and maintenance of road infrastructure should be based on the principle of maximizing road function (according to SLFJ) and the fulfillment of green open spaces on sidewalks and around (according to SRTH).

This study was intended to examine the pattern of interaction and mutant distribution of endophyticbacteria as a result of the transformation of the gfp gene in rice plant tissue in vitro. This study used 5isolates of rice endophytic gfp mutants namely IM-1, IM-3, IM-8, IM-24, IM-25. The study wasconducted in two stages, stage I using a simple Complete Complete Design (RAL) and stage II usingfactorial Complete Randomized Design (RAL) with a factor of 1: the type of plant tissue and factor 2:the type of mutant isolates.The results of the study of patterns of bacterial interactions in rice tissueculture showed that the percentage of infections of 5 gfp mutant endophytic bacteria isolates rangedfrom 4% -17%. The highest percentage was in mutant isolates IM-3 + gfp (17%) and the lowest was inmutants IM-8 + gfp (4%). The interaction pattern was not significantly different from the parametersof seed germination time. On the other hand, in observing the distribution of bacteria that infect ricetissue, they showed different pattern. Mutant IM-1 + gfp infection is higher in stem tissue, whereasIM-24 + gfp mutant infection is higher in root tissue and IM-25 + gfp mutant infection is higher inleaf tissue. Mutant infection of IM-25 + gfp in leaves had the highest number of colonies reaching1.64 x 109 cfu/ml.

The increase in web traffic and the development of network bandwidth that is relatively faster than the development of microprocessor technology today causes the one point server platform to be no longer sufficient to meet the scalability requirements of web server systems. Multiple server platforms are the answer. One known solution is cluster-based web server systems. In this study, a cluster-based web server system would be designed with the Never Queue algorithm and continued with testing the distribution of web workload on this system. The tests were carried out by generating HTTP workloads statically (with fast HTTP requests per fixed second) and dynamically (rapid HTTP requests per second that change or rise regularly) from the client to the web server system pool. Followed by analyzing data package traffic. In this study, the results of static testing with rapid HTTP requests per second which still showed that the Never Queue algorithm distributed HTTP requests to the web server system pool properly and got HTTP replies that tend to be stable at the HTTP average of 1031.8 replies/s. As for the rapid parameters of TCP connections, response times and errors increased with the rapid increasing HTTP requests generated. The average output was at 2,983 Mbps.
