Abstract

The Walet bird`s nests are believed to have some healing power for a number of diseases. Therefore, they are highly valued commercially, so that the drive to collect them are very strong from hazardous places such as caves,cliffs, steep shoves, dense forests, etc. Efforts to give artificial homes for the Walet birds are promising for business, espe-cially for the much lower workers safety risks and more stable best`s quantity produced. Some challenges have to be able to overcome resorting to the regulating power of a mi-crocontroller. First of all, to atract the birds, the design of would be home should be stu-died thoroughly, including its location away from the disturbing human activities. Second, the right indoor atmosphere condition should be guaranteed. A set of hardware can be developed to provide a monitoring system on the temperature, humidity as well as the illumination level of the room dedicated for the Walet. To maintain the right temperature and humidity, an automatic water sprayer unit is added during the dry days of the year. A programmable Walet sound reproducing equipment is vital to safe the farmer`s time to operate it manually.

Abstract

Broiler poultry owned by KUD Sedya Mulya interlaces cooperation with PT. Surya Gemilang Pratama. According to standard given, poultryman is expected to be able to produce broilers and the average of their weight must be 1.85 kilograms for 35 days and also their death rate must be under 5%. According to data records, KUD Sedya Mulya could not complete standard given by its partner. One of way to increase effectiveness and improve productivity is applying a method known by 5S program (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke). This research uses Analytical Hierarchy Process (AHP) method to define the criterias and sub criterias and also prioritise them. The next step is designing some improvement suggestion alternatives according to selected sub criterias based on 5S concept and then choosing the best improvement suggestion alternative and applying it. The last step is comparing productivity of previous raising procedure and productivity of 5S concept applied. According to productivity comparison analysis result, after 5S concept applied, we inform that there is a raising of production by 8.32%, there is a raising of labour productivity by 8.32%, there is a raising of time productivity by 2.19%, there is a raising of food consumed productivity by 16.63%, there is a raising of electricity usage productivity by 15.79%.

Abstract

Mitsubishi Chassis is steal that contains 0.044% Carbon. The limitation is especially on its corrosion resistance; therefore. The aim of the study was to know the effect of hardening on the process of quenching and tempering toward hardness, micro structure and corrosion resistance of Mitsubishi Chassis FE 114 to increase the age of material usage. This study used material of Mitsubishi chassis FE114 of truck vehicle. It was done heating by using furnace (heater oven) on temperature 850°C for about 30 minutes. After that it was quenched by using viscosity variation of oil media with number of viscosity SAE 50, SAE 90 and SAE 140. To know the material characteristics after quenching and tempering, it was done hardness, micro structure, and corrosion testing.The result of this study shows that the value of hardening of Mitsubishi Chassis FE 114 increases on tempering of the hardness about 160.431 BHN on specimen quenching with oil media SAE 50, SAE 90. On the observing of micro structure, heating on quenching process and continued by tempering 200° C for 30 minutes occurred on perlite and ferrite phases. The corrosion speed before quenching process is 46.39 mm/year. The resistance of corrosion decrease after doing quenching process for all viscosity variation oil media. This shows that corrosion resistance of Mitsubishi Chassis FE 114 can not be increased with quenching process.

Abstract

Information system to diagnose diseases with fever symptom using expert sys-tem based on SMS (source massage service). Computer is a electronic instrument which is very needed for data processing in order to provide information fast and accurately. One of the computer application is used by health expert to make a system to deliver information of diagnose disease result based on consultation data from a patient. Disea-se detection done by collection of symptom of every diseases which has a certainty factor (CF).The health information system is made using Delphi 6. Microsoft Access 2000, Mysql and SMS Gateway version 11.4. The investigation result shows that health infor-mation system can decide the same diseases different CF.This is because of source di-seases having the same symptom with an another diseases . The CF is obtained from the calculation between CF symptom and CF expert system. The access of the information is done by SMS medium with SMS Gateway connecting the computer with terminal hand phone.

Abstract

Analysis performed on web server logs have traditionally been widely used to see the web visitor activities such as determining the amount of access to web pages, anyone accessing the web user and the time to visit the web and visited URLs and more statistical analysis. But it is still very little information about the relationship between exis-ting data on the web, the sequence of requests made by a user or group of users who have access to a web site. To overcome these problems required a web mining tech-niques. Web mining is a technique to automatically discover and extract information on the web. This study used different techniques to sequential pattern Apriori algorithm to identify patterns of web site navigation. The the applications that have been made will show recapitulation of information about the number of visits per day, a search of browser used, details of visits that include IP addresses, proxy server, the location of the sequen-ce pattern visitor and web traffic. Web navigation patterns using Apriori is able to produce the sequence pattern of answering pages accessed by visitors. This pattern always varies depending on the minimum support are included. The higher MinSup, so little sequence variation pattern of visits and reverse the lower the value of the Minsup more and more variations of the sequence pattern of visits by users.

Abstract

Galeria Mall Jogjakarta is one of the shopping centres with underground parking lot. The CO (carbon monoxide) influences visitors and workers within. Known that the room could be fatal, the basement is not fulfilled with air channels so that the exhaust gas vehicles trapped in the parking space itself. Those, will eventually cause disturbance to human health. Therefore research is needed to determine how far the levels of CO (carbon monoxide) in the parking lot in the mall land. Research methods includes the way of measurement of CO levels, temperature, humidity, wind speed and the number of vehicles from 09.30 - 14.30. The samples were taken for analysis (CO), Thermoter (temperature), Anemometer (wind speed) and Pyrometer (moisture). The study areas were including motorcycle parking areas, the midde of motorcycle and car parking areas and the last is the car parking areas. Result of the research is average level of CO pollution ranged from 16,100 to 19,550 μg/m3 at 09.30 A.M by the number of motor vehicles and cars are 49, while from 12:00 to 14:30 A.M between 34,116.67 to 45,616.67 μg/m3 with a number of motor vehicles and cars we 544. The conclusion of the study is that between 12-14.30 A.M there was CO standard normal overload within the underground parking areas of Galeria Mall. Re study of the facilities is required, sonly.
