Abstract

The use of LPG as a fuel alternative to fossil fuels may be more effective and practical. But considering this type of fuel has no color, and is classified as a highly flammable type, if there is a slight leak and the handler is late, that is can cause material losses as well as fatalities. This research aims to (1) create a prototype Arduino-based that can detect LPG gas leak using MQ-2 sensor, Buzzer, and GSM Module. (2) provides information to the user that there is a LPG gas leak. This research uses research and development methods. This research produces a gas leak detector technology system that (1) integrates MQ2, Arduino UNO, Buzzer and GSM Module, if the detected gas concentration level is ≥5000 PPM, this prototype will provide information on the presence of gas leakage to the user through four outputs, LCD for displays the results of reading the concentration of gas, buzzer as an alarm, and the GSM module for sending sms and making phone calls. (2) This warning information will allow users to reduce the risks and potential dangers caused by LPG gas leak.

Abstract

In the case of gas transmission, the calculation of the gas delivered and the gas currently in the pipe is of course required to be a safe amount in the sense of neither less nor more. A condition where the amount of gas is less than the minimum value of the pipe capacity can cause damage to the pipe because the pressure is below the normal point. Meanwhile, conditions where the gas in the pipe exceeds the maximum capacity value is also very dangerous because it can cause accidents such as pipe leaks and explosions. Therefore, this research was carried out to determine the value of forecasting gas demand by PT PGN to be able to find out the range of gas volumes that must be stored and then distributed by Pertamina Gas to meet PT PGN's demand. Forecasting is a technique of predicting the influence of prevailing conditions and situations on future developments. The method generally used in forecasting is the quantitative method using the time series method.

Abstract

PT.XYZ is a company engaged in the business of trading industrial and fabricated goods. PT.XYZ often experiences excessive accumulation of thinner which will cause the storage warehouse to pile up. Therefore, this research aims to develop an effective forecasting model in anticipating the use of Thinner No.17 Jotun at Indonesia . The right forecasting method can help companies plan inventory, reduce the risk of overstock or stockout, and increase efficiency in the supply chain. The development of usage from month to month is increasingly uncertain, so the company wants to know how much Thinner expenditure will be used in the following month by referring to the previous month's expenditure using the single moving average, weighted moving average and single exponential smoothing methods. The software used to assist in this research is POM-QM. From the results of research using the Simple Moving Average method, this method has a MAPE value of 5,841%, the forecast size for the next period, namely period 13, is 285 pcs. This shows that the Simple Moving Average method is the most appropriate method to use to solve the problem of using Thinner No.17 Jotun experienced by PT. XYZ because it has the smallest error value. So it can be concluded that the application of this method provides the right solution for the needs of Thinner No.17 Jotun in the next period.

Abstract

Planning project activities is one of the important foundations for project implementation so that the project can be carried out optimally. The schedule is part of project planning which is a parameter for the success of a project. Scheduling needs to be considered to determine the duration and sequence of project activities, so that a logical and realistic project schedule can be formed. The aim of this research is to obtain the critical path of a project activity along with the duration required during the project and to obtain the probability of the project reaching the expected target. In this research the Critical Path Method (CPM) and the Program Evaluation Review Technique (PERT) method are used. . Based on the results of the calculations and discussion, it can be concluded that in the function setting activity a critical path was obtained which consists of 7 activities, namely A – B – F – G – H – I – J with a duration of 57 days. It was also found that the probability of the project reaching the expected target within 76 days or less was 0.9978 or 99.78%.

Abstract

PT X is a company engaged in producing ships. PT In the research, a validity test was carried out to determine whether the questions given did not produce deviant (valid) data as measured by the Pearson correlation. Then, this research also carried out a reliability test to determine whether the measuring instrument remained consistent if the measurement was carried out twice or more using the Cronbach's Alpha (a) formula. From the research data, valid variables were obtained, including; Friendliness, Good communication, Willingness and readiness, Efforts to establish good relationships, Easy to contact, Cleanliness of the room, The room is not noisy, Quick service, Bright room light, Does not discriminate between subcontractors, Quick approval of offers, Fast issuance of contracts, Comfortable room, and Accuracy Employee. In this research, all variables were found to be valid, so the next step that must be taken is to carry out reliability calculations because the variables in the questionnaire are valid. From the results of reliability calculations, the Cronbach's Alpha value > significance level value is 0.770 > 0.6, so the instrument is said to be reliable. From the research obtained with IBM SPSS software, it is useful for carrying out validity and reliability tests in analyzing the level of subcontractor satisfaction with facilities and services in the Procurement Services Division of PT X's Supply Chain clearly and optimally.

Abstract

The problem in the industrial sector that is often encountered is the problem of queuing. Queues occur when there is an imbalance between services and services offered, causing consumers to wait to get service. Laboratory queue simulation using Arena software. This research was carried out with the aim of analyzing the queuing conditions that occurred during the material A testing process at the XYZ Laboratory through simulation using Arena software. After carrying out a simulation with the Arena software, it was discovered that there were no queues for the material A testing queue activity at the XYZ Laboratory. From the results of the simulation data processing for material A testing queues in the XYZ laboratory, there are no queues and service times are optimal, so there is no need for corrective solutions. Based on the results of verification and validation, H0 is accepted because the value 0 is in the range μ1 – μ2 so it can be said to be valid. This states that the total time in the real situation (real system) is not significantly different from the output results in the Arena simulation that has been created.

Abstract

The economy of a country is influenced by many important factors, including its industry and trade. This research was conducted to determine the influence of coaching, certification and socialisation activities on the smooth running of MSME businesses in Mojokerto Regency. Data collection was carried out by distributing questionnaires to the MSMEs concerned and then processed with SPSS software using multiple linear regression. The results of the study began with a data quality test that produced all variables that were valid and reliable, then the classical assumption test produced normally distributed data that passed the multicollinearity and heterokedasticity tests. For the equation of the three independent variables in the state of zero, the variable of business smoothness is valued at 11.846, if the variable of coaching activities increases by one unit, there will be a decrease in the variable of business smoothness by 0.045, if the certification and socialisation activities increase by one unit, there will be an increase in the variable of business smoothness by 0.021 and 0.086. The hypothesis test produced a coefficient of determination of 0.012, so the three independent variables explain the business smoothness variable by 1.2%, the F test concluded that the three independent variables (simultaneous) did not have a significant effect on the business smoothness variable, the T test concluded that the three independent variables (partial) did not have a significant effect on the business smoothness variable.
