The Effect Of Liquidity And Solvency On Profitability In Food And Beverage Companies
Get PDFThis research aims to analyze the financial performance of three large companies in the food and beverage industry listed on the Indonesia Stock Exchange, namely PT. Mayora Indah Tbk (MYOR), PT. Indofood Sukses Makmur Tbk (INDF), and PT. Garudafood Putra Putri Jaya Tbk (GOOD), during the 2019-2023 period. This analysis uses various financial ratios, including liquidity, solvency and profitability ratios, to provide a comprehensive picture of how each company manages their finances in the face of intense industry competition. The research results show that MYOR has better performance in terms of liquidity and cash management compared to INDF and GOOD. However, all three companies face significant challenges in achieving optimal profitability, with Return on Investment (ROI) and Return on Equity (ROE) well below industry standards. Further regression analysis shows that the tested liquidity and solvency variables do not have a significant influence on profitability, indicating the need for a more effective financial strategy. These findings underscore the importance for companies to improve the efficiency of asset and equity management and manage debt more strategically to support long-term sustainability and competitiveness
A Coordination Analysis Of 20 kV Medium Voltage Distribution Protection System On LH 04 Gi Blang Pidie Feeder
Get PDFIn the electrical energy distribution system, power distribution systems, especially in the SUTM network, SKTM, and 20 kV distribution substations, can experience various obstacles that stop the distribution of electrical energy to consumers. In addition, various disturbances also cause damage to electrical equipment. One way to minimize or minimize the outage area and damage to various components that are electrified due to interference, a protection system is needed. More specifically, in avoiding the duration (SAIDI) and frequency (SAIFI) of customer outages, it is necessary to set the protection relay properly as a form of protection or protection so as to minimize the position and place of interference. Coordination of the protection system pattern of a network is said to be good if it can minimize the number of outages as small as possible based on the distance and location of the disturbance. After calculating the protection coordination system with ETAP simulation. In the ETAP simulation, the sequence of protection coordination has run well and the protection works in the correct order according to the calculation settings that have been input. The advantage of good protection system coordination is that if there is a disturbance at one point of the distribution network, it does not interfere with the production process in other distribution networks so that the number of outages can be reduced and the affected area can be localized as small as possible. The results of the coordination of the installed protection system on the distribution network utilizing ETAP can be seen that the existing OCR and GFR settings are still not good, for example, if there is a disturbance in the LH 04 feeder network, the relay sequence that releases the contact is LH 03, causing many customers to go out that should not be included. resetting OCR and GFR protection on the distribution network can be based on the fault current that occurs along the network. Overcurrent disturbances are used for low setting and high setting on OCR and GFR protection, for curve characteristics using inverse time standards combined with instantaneous relays. By resetting the OCR and GFR on the distribution network, the reliability of the protection system coordination and the selectivity of the protection sequence are better than the existing conditions so as to create an ideal protection system coordination

Data techniques are analyzed by preparing data and organizing data, reducing data and presenting data. The results of the study indicate that the Human Resource Capacity of employees in the Protocol and Communication Section of the Leadership of the Buton Regency Regional Secretariat is quite adequate. Employees already have good experience in carrying out their duties and responsibilities, both in preparing materials, facilitating guest services, and arranging protocol procedures. Knowledge of protocol procedures can be obtained by some employees through Bimtek and public relations and protocol training organized by both the Ministry of Home Affairs of the Republic of Indonesia and private institutions. Regarding the quality of employee work, some are adequate. This can be seen from the results of work in providing protocol services for regional leaders and protocol services for Regional Guests. Regarding the quantity of work, it shows that the workload and volume of work are very large and not balanced with the number of ASN available. So that the quantity of employee work completed is less than optimal. In the sense that all activities can be completed, but some activities are not of maximum quality. In terms of time utilization, it shows that employees are able to complete tasks and work. The ability to collaborate with all parties is one of the supporting factors so that all tasks and work can be completed properly. However, discipline in time utilization is still lacking
