Abstract

Heat transfer in diesel engines is known to affect engine efficiency and emissions. Increased heat transfer to the combustion chamber walls reduces the pressure in the cylinder and the average gas temperature, which reduces the work transferred to the piston per cycle. Therefore, the amount of heat transfer in an engine largely depends on the efficiency of the engine. Changes in gas temperature due to heat loss from the combustion chamber also affect the formation of pollutant emissions. Higher temperatures in the cylinder promote NOx emissions, while lower temperatures in the cylinder create Particulate matter in the exhaust. Engine heat transfer is important, so engine heat transfer results must be accurately estimated.

Abstract

As with the engine ignition system, the spark produced by the manufacturer's standard CDI is limited or known as a CDI limiter, in contrast to non-limiter CDI which has no limits or has a higher spark limit on the engine so that it can produce engine performance up to a higher RPM. higher and produces maximum engine performance. Weaknesses in the factory standard CDI can be overcome by replacing it with a racing CDI. Racing CDI has the same quality or even better than standard CDI. Racing CDIs are made by local manufacturers and from abroad and are now easily available in spare parts stores or motorbike repair shops throughout Indonesia.

Abstract

CV Harico is a manufacturing company that produces briquetted charcoal final products. In this research, the company had problems with the quality of charcoal briquettes which did not meet standards, amounting to 12% of the production process, including slanted shapes, holes and cracks. In this research, problem solving is done by combining the Six Sigma and TRIZ methods to get suggestions for improvement. The Six Sigma method is an organized and systematic method, Six Sgma has 5 stages, which can be known as the DMAIC phase. Based on the calculation of the DPMO value and the calculation of the sigma value at the measurement stage, the average DPMO value for October 2023-November 2023 was 27219 with a sigma value of 3.43. Based on the identification results using the Fishbone Diagram method and the FMEA method, the largest defects were found in the slanted shape of the charcoal briquettes, these results were obtained from the factor with the highest RPN value that caused defects. Proposed improvements based on the TRIZ method analysis include providing training, carrying out periodic actions, making maintenance schedules, evaluating work processes, changing tools to reduce the occurrence of defects. The aim of this research is to analyze the problems that occur as well as efforts to control quality and reduce product defects in briquetted charcoal products.

Abstract

A surveymeter is a measuring instrument that functions to detect radiation exposure doses, which uses a Geiger Muller gas filled detector with the initial unit of sievert converted to microsievert (μSv/hour). In this research, we fabricated an IoT-based surveymeter and tested the response of the gas fill detector used to changes in exposure factors. Before collecting data, it is mandatory to set parameters on the control panel to determine the radiation exposure dose to be measured. Measurements are carried out on a mobile X-Ray with parameter settings including tube voltage (kV), tube current (mA), and exposure time (s). From the results of research that the Geiger Muller gas filled detector responds to the radiation exposure dose that has been determined on the control panel and fired by mobile X-Ray, the results detected by the detector will be displayed in the application in the form of Counts Per Minute (CPM), µSv/h, + /- and data can be stored in the database. The higher the tube current value given, the smaller the radiation dose value obtained. In other words, the gas fill detector responds with a dose value that is directly proportional to the X-ray tube voltage value and inversely proportional to the X-ray tube current value.

Abstract

This study aims to assess the impact of the General Intelligence Test (TIU), National Insight Test (TWK), and Personal Characteristics Test (TKP) on the success of the Basic Competency Selection (SKD) for Civil Servant Candidate (CPNS). Using data from participants in the Ministry of Law and Human Rights' SKD selection in 2023, we employed univariate analysis, simple bivariate analysis, and binning methods to comprehend variable relationships. Results reveal non-normal distributions for TIU, TWK, and TKP scores, highlighting the intricate nature of distribution in CPNS selection. While a positive correlation exists between variable values and total SKD score, binning analysis emphasizes TKP competitiveness over TIU and TWK scores. These findings offer practical insights for SKD participants to prepare effectively, with a focus on TIU, TWK, and TKP. Additionally, they contribute to transparency and effectiveness in the CPNS selection process. Further studies are recommended to explore additional factors, like age and gender, for the development of more holistic and accurate selection methods. This research supports enhancements in the adaptive and efficient CPNS SKD selection system.

Abstract

The Rectorate's field of function is the function of improving performance, safety and efficiency in the use of elevators where the vertical transportation system is used as a tool to facilitate the activities of people and goods to move between certain floors in a building. Elevators are used as a tool to facilitate the activities of both people and goods to get to the floors In certain office and lecture buildings, it is a one-story building in building D which uses an elevator as a means of vertical lift transportation. Effective and efficient elevator planning is needed so that the elevator can be operated optimally. This should have a big impact on the comfort of building occupants as elevator users. One of the consequences of inadequate elevator planning is the occurrence of queues during peak hours. Therefore, some analysis of elevators in lecture and office buildings is needed. Elevator efficiency can be analyzed by calculating elevator requirements which depend on several variables such as lifting speed, lifting capacity, elevator waiting time, number of building occupants, and how large the building is. Meanwhile, the effectiveness of the lift can be obtained from the scheduling preparation and budget requirements involved in each lift's preventive maintenance. The research methodology used in this research is interviews, observation, secondary data collection, and data processing. From the results of data processing it can be concluded that the efficiency and effectiveness of the lift is 75% of the lift requirements for the 2 lift units provided. The research results also show several preventive maintenance schedules and preventive maintenance budgets within a one-year budget period.
