Abstract

The groved surfaces are widely researched to reduce pressure drop and control a flow on the surface. In applicative fluids flow is turbulen. So, the grove addition capable of affecting the boundary layer condition near the wall pipes. This will greatly determine the pressure drop and the flow patterns that occur during the fluids flow. The purpose of this researched is to analyse the impact of the number of grooves in pipes against the pressure drop and the occurred flow patterns. In this researched, we used 3 pipes, which total of grooves were 4,8,16 and the pipes without grooves that used as comparator. The observed flow was two phases flow ( air-water). The researched pipes used acrylic pipes with diameter of 1 inch and length of 100 cm with the groove used was type of scalloped groove. Pressure drop occurs in all of the grooves ; 4,8, and 16. The highest pressure drop decrease occurred in groove 16. When there was drop in pressure drop in every single of groove, in low air discharge, bubbly that firmed was more tightly without making slug flow. When the debit was getting bigger, the bubbly was reduced and followed by the emergence of slug flow. The changes in water debit in the decrising of pressure drop in every single of drop, shows the dencity between the bubbly and slug flow that firmed

Abstract

The purpose of this research is to create a Web-based Literature Culture Information System Besemah Pagar. Besemah Literary Culture comes from the besemah tribe that grew up in Kota Pagar Alam. Besemah literature is now rarely heard by the Pagar Alam people inside and outside the City of Pagar Alam and is also almost unknown to the public, especially Pagar Alam among young people today. The system development method used is Rapid Application Development. With the web-based information system program, the public will gain knowledge about the literary culture that is weak in the City of Pagar Alam, and also help disseminate information in the introduction of the culture and literature to the public at large to increase outside tourists in supporting the City of Pagar Alam program. Tests carried out using Black Box Testing with no error results. The results of research in the form of Web-based Literature Culture Information System Weak Besagar Pagar that can be implemented and used by the general public.

Abstract

The data of non-active students is an obstacle in a university because it is counted as a student body, thus affecting the lecturer ratio. For that reason, in order to improve the lecturer ratio, a way is needed in addition to adding lecturers, but also by evaluating the data of students who are not active and active to be filtered back by looking at academic data that is known so that students can continue their studies or should be advised to resign or also drop out . To solve these problems a system model is needed that can recommend students as drop out students and can also provide other recommendations that can be used as evaluations. Case-based reasoning method is used to see new data matching with old data, where active student data to be evaluated will be matched with student data that has been dropped out or received a warning letter, so that it will be used as a new solution. Case-based reasoning methods can help in recommending students to drop out or get a warning letter.

Abstract

The power generated by a power plant driven by windmills and waterwheels and solar power is unstable,. each depends on wind speed, water flow, and solar radiation, repeatively. This results in the acquisition of energy not being optimal if the load is not adjusted to the capability of the generating power. In this study a load control automation system has been created that can adjust to the ability of the resource so that optimal energy is obtained by the hysteresis method. When the power goes up and down the load adjusts hysterically, so that optimal energy is obtained.

Abstract

The Geothermal power plant at PT Geodipa Dieng has been operating for more than 10 years. It has undergone for several improvements including the replacement of turbines where to increase turbine efficiency. Before changing the turbine, the efficiency of turbine has decreased due to several factors, such as decrease in load, maintenance, usage, the lifetime etc. Therefore it needs to be analyzed the effiency of the turbine to find out whether the turbine is still feasible or not, and to find out whether it has necessary to replace the turbine again. The result of the turbine generator efficiency are obtained in one year from April 2017 to March 2018 with an average value of 70-85%. Based on the literature, the value is still at the turbine efficiency standard in general, which is 60-80%. So the turbines can still be categorized reliably and do not need to be changed.

Abstract

Searching is one of the important features on the website, but it is not uncommon for users to make typos when typing keywords. Typing errors of these keywords is usually referred to as typo. This study aims to build a system by providing suggestions for correcting typos in the search feature. Keywords search correction are obtained using the Damerau-Levenshtein Distance Approximate String Matching algorithm by to calculate the editing distance of each word in a keywords with each word in the Indonesian word dictionary. Testing was carried out as many as 40 experiments, with 10 keywords and 250 articles taken randomly. The test results show the Damerau-Levenshtein Distance algorithm is able to provide precision and recall values of 91.24% and 89.58% in providing keyword improvement suggestions. With the improvement of the system, each trial increases with precision value of 0.80 and recall value of 0.98

Abstract

Electric Ducted Fan (EDF) is an electric propulsion consist of duct, fan and electric motor with main power source is from battery which generates compression air for thrust. EDF is used as an alternative propulsion for high speed UAV especially for target UAV or ?bomb? controlled UAV. It?s design is very simple and no need extra maintenance compared to jet engine. Design process of an EDF is more simple than a jet engine, nevertheless it could obtain enough thrust for high speed flying. The aim of this research is to design an EDF as an alternative propulsion for high speed UAV and performance analyzing of EDF using analitical approach. Design of EDF produce an EDF with inlet and outlet diameter are 70mm and 60mm. Total length of EDF is 116,1mm. Performance analysis of EDF shows that by 700W of motor power could reach 16N of thrust which is accepted performace for 70mm EDF.

Abstract

Biocomposite material is a common material used in biomedical application. One of medical problems related to bone restoration which caused by accidents and injuries resulted in fracture bone parts. Biocomposite (Sagoo/PMMA) is being developed as a solution to solve that particular problem. In current research, tensile and flexural strength of sagoo/PMMA is tested and examined. There are correlation between value of tensile strength, value of bending strength, and curing time, with maximum tensile strength and bending strength were achieved by curing the specimen for 12 hours, with the maximum value of tensile strength is 3,337 MPa, and the maximum flexural is 2,653 MPa. The minimum tensile strength was achieved by curing the specimen for 6 hours with minimum value of tensile strength is 1,502 MPa, while the minimum flexural was acquired at curing time for 24 hours with minimum of bending strength is 0,536 MPa

Abstract

Performance issues are not only important for upper middle and large companies, but also important for Small and Medium Industries Creative Industries. To evaluate the current condition of a creative industry, the creative industry needs to determine the multi-criteria Key Performance Indicator (KPI) properly and correctly. Therefore in this study, researchers tried to design a Key Performance Indicator (KPI) for the creative industries of bamboo crafts in the Godean district of Sleman. The design of KPI uses the Balanced Scorecard method which includes setting strategic objectives, determining key performance indicators (KPI). From the results of the study obtained 10 KPI, namely: the level of sales growth, the level of customer growth, the level of customer satisfaction, the level of customer complaint fulfillment, the level of production speed, the number of products produced by labor, the percentage of defective products, the percentage of the level of effort to repair defective products, the level of productivity employees, and employee job satisfaction Keywords: Performance, Performance Indicator, Key Performance Indicator, Balanced Scorecard, Creative Industry.
