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.

Abstract

This research was based on a flaw found in observations made during a period of one month with the location object of MSMEs Hartono tempe. The discovery of this defect has an impact on the quality of tempeh so that it can reduce people's purchasing power in tempeh. The purpose of this study is to find out how good the quality of the products produced, find out how big the level of defects in tempeh production is, and find out the causes of product defects using the SQC method. The use of the SQC method is used to control the quality of the initial process of the finished product, as well as certain quality standards that have been agreed upon by the company. Data was collected through interviews with company owners and observations for one month on the tempeh production process that occurred. Data shows that defects in tempeh production include the inclusion of foreign objects, uneven shapes, and damaged packaging. After observation, it turned out that damaged packaging was the most common cause of defects during observations. So, we will make a suggestion, namely making a plastic adhesive device (Sealer). In addition to reducing defects due to damaged packaging, the manufacture of sealers also speeds up the plastic gluing process when producing.
