Abstract

Quality improvement activities can help companies maintain and improve the quality of their products bymaking improvements to the level of being broken product to zero damage. PT. Gemilang Inti Sukses is aProfit-oriented Chicken Porong Home Industry engaged in the agribusiness sector, in the process of cuttingchickens there are several obstacles that can affect the level of quality of chicken slaughtered products,Therefore this study aims to determine the quality problems of chicken slaughter and increase the resultsproduct quality at PT. Gemilang Inti Sukses. The method that will be used in this research is the Six Sigmamethod on the DMAIC (Define, Measure, Analyze, Improve, Control) concept. The results showed that ofthe 20 days sample that was 6,540 tails, it was found that the number of slaughtered chickens was 2,230chickens with the details of bruised chicken heads, broken chicken wings, bruised chicken body parts, lessclean feather extraction, and internal taking. not clean enough. While the company's performancemeasurement is at Sigma 3.85 level with a 9.292 DMPO value, which means that in 1 million pieces ofchicken there are 9,292 chickens that are deformed. From the Pareto diagram, it is known that 80% of thedefects are broken chicken wings and bruised chicken parts. Then from the cause and effect diagram it isknown that human resource factors are the main cause of broken chicken wing flaws and bruised chickenbody parts, therefore from the results of this study the company needs to improve quality with morediscipline towards human resource operational standards and conduct supervision and evaluation ofemployee performance. Keywords: Pareto, Quality Improvement, Cause and Effect, Six Sigma-DMAIC.

Abstract

Medowo village is one of the villages in Kandangan Districts residing in hilly area. Geographicalcircumstances make the Medowo Village has a variety of picturesque hills land and fertile. Some of which arenature tourism, nature tourism Gandrung Hill, Plengsengan Refreshing Hill (PRH), and Waterfall Sumber Jodo.The existence of the tourism traffic flow increasing at rush-hour. Lack of supporting facilities infrastructurearound natural tourism makes the reduced comfort felt by road users.To find out the impact of traffic on the roads of the third, then conducted the research along with trafficperformance analysis using the method of MKJI 1997 and the Balanced Scorecard SWOT analysis. From theresults of the calculation of the performance of the traffic road of in the third obtained the results of A road levelof service or Level Of Service (LOS) worth 0.02 - 0.03 impact analysis using SWOT and Balanced Scorecardrefers to the four (4) criteria i.e. strengths, weaknesses, opportunities, and threats.

Abstract

The need for measuring the mechanical properties of material in the Material Science course makes thecharpy impact machine to be immediately presented to be a supporting tool as well as a reference forstudents in carrying out impact testing. The purpose of this study was to find out how to design and createa charpy impact machine, find out how to work and analyze performance based on the impact energyreceived by the specimen and find out the impact on student learning interest in the Materials Sciencecourse. This research is a design research that ultimately produces a product. The performance of the tooluses ten steel specimens with dimensions of 10mm x 10 mm x 55 mm indicating an average impact priceof 1,509601 J / mm2. The measurement results of the learning interest questionnaire showed an indicatorof student interest in the presence of the charpy impact testing machine in the materials science course at73.68%..Keywords: design, impact, charpy, learning interest

Abstract

Traffic Jam is a problem that often occurs in transportation problems. Juanda Junction is one of theintersections that often experience traffic jam. The causes of traffic jam arise from many things, includingthe presence of side barriers, the absence of markers so that the traffic light that works is not optimal.Based on the results of the initial survey, it was found that the duration of the green light in each pendekawas not adjusted for how many cars and motorcycles were passing. North approacher where most cars andmotorbikes are passing but get fewer duration of green lights than other approaches. This shows lessoptimal traffic light settings. The use of fuzzy method is expected to make traffic light settings moreoptimal because the old green light produced is more flexible in accordance with many cars andmotorcycles that pass through an approach. The results of the study were obtained for vehicles passingthrough the northern approacher as many as 26 cars and 177/cycle obtained manually by the green light for43 seconds and with fuzzy 45 seconds. Western approacher with many vehicles passing by 25 cars and170/cycle motorbikes received a 51-second manual green light and fuzzy 42 seconds. As well as for theeast approacher with many vehicles passing 24 cars and 168 motorcycles/cycle get the green lightmanually 53 seconds and with fuzzy 42 seconds.

Abstract

Exhaust emissions generated by motor vehicles are increasing as the number of motor vehiclesincreases. Carbon monoxide (CO) and Hydro Carbon (HC) is harmful substance contained in exhaustemissions. This study aims to make emission test (prototype) to measure CO and HC levels on exhaustemissions. This type of research is an experimental research with the waterfall model design method.Arduino-based emission test (prototype) with working system of CO and HC concentration on emissionwill be read by MQ2 and MQ9 sensor connected with Arduino and displayed on lcd screen in digitalnumber using C language program. Further data on the prototype is taken and compared with the dataon the gas analyzer using the T Test method. The results of testing the CO and HC levels on emissiontest equipment (prototype) with the results of testing using a gas analyzer still showed a significantdifference with the significance value of CO level readings of 0.319 and HC levels of 0.896. Keywords: exhaust emissions, MQ2, MQ9, Arduino
