Analysis of the Combination of Vendor and Consultant Executors Through Risk Management Moderation on Decision Making for the Development of the E-Procurement System at PT XYZ
Get PDFThe selection of potential executor combinations is the initial stage in planning the development of an e-procurement system. The aim is to conduct studies and analyze each combination of executor vendors and consultants based on their impact and scale of importance on cost, time, quality, and flexibility. This study will lead to selecting a recommended combination with the least risk value and the most important based on the current conditions of PT XYZ. The method used in this research is a quantitative method with the MANOVA test to assess differences in the influence of each executor combination on costs, time, quality, and flexibility. Next, a risk analysis is carried out using the FMEA method to assess the Risk Priority Index and determine risk mitigation. After that, the best combination of executors is selected based on the risk value and the interest scale. The research results show that there are differences in the influence on cost and quality of all combinations of executors, but different combinations of executors do not have a different influence on time and specificity. The results of the risk analysis show that there are influences of risk management in the relationship between each type of executor on costs, time, quality, and flexibility, which can be seen from the decrease in the Risk Priority Index value for each risk event that has been identified due to risk mitigation. Finally, the results of selecting potential executor combinations using AHP show that combination 8 is the first potential with a value of 0.136, followed by combination 5 in second place with a value of 0.112, and third place is achieved by combination 7 with a value of 0.111. The fourth, fifth, and sixth places are each occupied by Combination 3 with a value of 0.101; combination 2 with a value of 0.098; and combination 1 with a value of 0.097
Analysis of the Effect of Temporal Changes on the Coolant Viscosity of the Pendinggin System on Motorcycles
Get PDFA combustion motor is a machine that converts from chemical energy to motion energy, where in the working system of a combustion motor produces power or engine rotation which is produced from the process of combustion in the combustion chamber (cylinder). In addition to producing power and rotation, it also produces heat (thermal) as a result of the combustion process. Excessive heat generated by the combustion process can also cause problems if not overcome properly, can cause overheating. Therefore, a good cooling system such as radiator coolant is needed, in the fluid cooling system there is viscositic (viscosity of the substance) which can affect the absorption of heat. The following are the test results at temperatures of 27.8oC (0.35dpa.s), 70oC (0.275dpa.s), 90oC (0.25dpa.s). If the viscosity value is low, then in the flow rate the faster the heat absorption and heat transfer will be more effective, while if the viscosity value is high, then in the flow rate the slower the heat absorption and heat transfer process becomes ineffective
Automatic Reading System of Scale Values on Webcam-Based Measuring Vessel
Get PDFThe fuel measurement pump is an installation used to measure the quantity of liquid fuel (BBM) to be sold or delivered to consumers. In the transaction of buying and selling fuel at gas stations, the fuel measurement pump plays a crucial role. Therefore, this measuring device needs to be calibrated or re-verified, and supervision is carried out using a standard measuring vessel with capacities of 10 L or 20 L. Errors in reading the measuring vessel can occur due to differences in individual visual acuity. To address this issue, a prototype for automatic reading of measuring vessels is created using a webcam camera. This prototype utilizes the Raspberry Pi 3 B+ as an image processor and the Logitech C270 webcam as an image capturer. The image processing process involves segmentation steps, transforming the image into a grayscale and then into a binary image. This research involves two different types of fluids in the volume measurement of the measuring vessel, namely distilled water (equates) and petalite. The measurement results with the prototype show an average accuracy level of around 99,23%, an average precision level of about 99,37%, and an average error rate of about 0,77%. For the equated fluid, the accuracy, precision, and error levels are 99,48%; 99.76%; and 0,52%, respectively. Meanwhile, for the petalite fluid, the accuracy, precision, and error levels are 98,98%; 98,80%; and 1,02%, respectively
Analysis of the Enforcement of the Survival Clause for Foreign Investors in Indonesia Due to the Termination of the Bilateral Investment Treaty (BIT)
Get PDFThis analysis examines the legal consequences of Indonesia's termination of the Bilateral Investment Agreement (BIT) on foreign investment entering or planning to enter Indonesia after the termination date. Bilateral Investment Agreements or BITs are known as a legal umbrella for foreign investors investing in host countries, including legal protection for foreign investors in Indonesia. The Indonesian government has signed BITs with several other countries to strengthen cooperation in the investment sector. However, because the contents of the agreement are no longer to the country's development and the current investment climate and limit Indonesia's policy space in regulating matters related to the protection of national interests, Indonesia has ended many BITs. The consequence of Indonesia's termination of the BIT for foreign investors is that there is the potential for investment disputes to arise. In this situation, the provisions of the survival clause will apply to foreign investments made before the termination date, because even though the BIT has ended, there is a certain period for the BIT to still be valid for investments made before the end of the agreement period so that in other words the agreement remains effective in protecting investors from both countries who previously existed or who had carried out restructuring before the termination date of the BIT. For foreign investments that enter or will enter Indonesia after the termination date, protection can be obtained by creating a new BIT or through a Multilateral Investment Treaty (MIT) and Free Trade Agreement (FTA) where Indonesia as the Host Country is a party to the agreement
Effect of Compressive Strength and Tensile Strength Value on Fiber Concrete Using Bendrat Wire Fibers
Get PDFConcrete is a material used in modern construction and is a very important component in the manufacture of structures. Concrete has advantages, but also disadvantages, namely low tensile strength. To increase the tensile strength of concrete, fibers are added to the mix. One of the efforts made to increase the tensile strength of concrete is the addition of fibers to the fiber-concrete mixture. The purpose of this study is to examine the compressive strength and tensile strength values in fiber concrete if added with variations in fiber addition. An innovation in increasing the value of mechanical quantities in concrete is the use of bent wire fibers as a mixture in fiber concrete. This material is taken from former pieces in construction projects to connect steel reinforcement with Sengkang reinforcement and is also widely found in building shops. The fibers were also analyzed for microstructure using SEM (Scanning Electron Microstructure) tools. The length of this bent wire fiber is 13 mm with a diameter of 0.82 mm and has a minimum tensile strength value of 334.5 MPa. The variations in the addition of these bent wire fibers are 0%, 3%, 6%, and 9% of the total weight of the steel fiber. The soaking life of concrete is 7 days, 14 days, and 28 days. The results of this study show that the more variations in the addition of bent wire fibers, the compressive strength value of concrete and the tensile strength value of concrete will also increase. It can be seen that fiber concrete with an immersion life of 28 days with a variation of 9% added bent wire fiber has a maximum compressive strength value of concrete which is 63,645 MPa and a maximum value of tensile strength of 3,294 MP
