Abstract

Employee performance appraisal is an important thing to do in order to improve employee competence so that a company can develop. Performance appraisals are also used for employees in promotions, positions, or company employees who are unable to comply with procedures. Perum LPPNPI is one of the offices that carries out employee performance appraisals. In conducting a performance assessment it is not appropriate because the system is still using a manual system. This problem causes performance appraisals to be a little difficult to determine the best employees based on established criteria. Decision support system is a suitable system for evaluating employee performance. The method used is the AHP (Analytical Hierarchy Process) method using the principle that the chosen alternative must have the closest distance from the positive ideal solution and the farthest from the negative ideal solution from a geometric point of view by using Euclidean distance to determine the closest distance from an alternative. to the optimal solution. By using a decision support system is expected to facilitate the company in assessing employee performance appropriately.

Abstract

Power outages can disrupt service continuity, especially in service activities in the trade, hospitality, hospital, and industry sectors. Nowadays PLN electricity distribution often fails in distribution due to internal and external factors, to meet the continuity needs of electricity, other electrical energy sources are needed so that if there is a power outage from PLN, consumer needs for electrical energy are not interrupted. These sources of electrical energy are temporary to serve the electrical load in the use of electricity PLN is the main energy source. ATS (Automatic Transfer switch), is a tool that functions to move the connection between one power supply voltage source and another automatically. Or it can also be called Automatic COS (Change Over Switch), in this study a single phase ATS will be designed by reducing the number of Contactors to get more economical and easy results in maintenance. ATS in this study uses a relay-based control circuit and Time Delay Relay (TDR). From the test results, this tool can work well in the switching process manually or automatically. When PLN goes out, there is a delay of time for ± 6 seconds before the generator starts. This aims to keep the components from being damaged if PLN sometimes goes out for a moment.

Abstract

In today's era, the need for telecommunication, information and entertainment facilities that can be accepted and have high performance is definitely very much needed. To fulfill this, a network that supports its performance is needed. For now the network that is able to provide the best performance is optical fiber. In Indonesia itself, there is a rise in the deployment of fiber optic cables directly to the house or called FTTH. The city of Medan is one of the cities that is densely populated, especially for the North Sumatra area. With these conditions, the FTTH network design is suitable to be implemented in this location. In the design, a survey using GPS will be developed into Google Earth and AutoCad data. In the design data can be estimated about the number of devices, specifications and position of the placement of the device from the STO to the position of the customer. This data is to be developed along with calculation data based on FTTH GPON. In the design of the FTTH GPON network, the direct measurement results obtained the Power Link Budget value of -18.283 dBm for the downlink (-8.248) ns for the uplink at the farthest point, and the Rise Time Budget, which was measured at the farthest point. The Rise Time Budget is <70% with a value of (0.363) nm for Downlink and (0.251) ns for Uplink.

Abstract

Efforts to build Indonesia into an electricity-efficient country require a smart system in its control where the government is obliged to present various policies that can unravel various environmental problems with smart and fast concepts. Where in this research designThis automatic faucet control device that can save electricity is made by utilizing a Passive Infrared (PIR) sensor as the control center and detecting objects in the form of human body parts. This PIR sensor will send instructions to the Relay to move the solenoid faucet which functions as a water flow valve.[1] The results of the analysis show that the PIR (Passive Infrared) sensor on this tool can detect objects within a maximum distance of 150 cm meters. When the PIR sensor receives radiation from an object, the solenoid valve opens the valve to drain water. With the automatic faucet control that is used in the men's toilet, it can make it easier for humans because it can be done by an electronic device in the form of a sensor and a controller.

Abstract

The use of water energy worldwide has increased in recent years to reduce emissions. This abundant energy source has the potential for electricity production of 75 GW throughout Indonesia. However, its construction requires a lot of time and money, so it has not become the main choice to be a solution to energy needs. In this study, we will observe the process of generating electrical energy in Southeast Aceh Regency whose electricity needs are supplied from the Lawe Sikap PLTM which has only been operating for one year, and the Sepakat PLTMH which has been operating since 1997 to determine the level of efficiency and reliability. By measuring the electrical energy and water discharge available each period by the operator at each power plant during January-February 2022. The results show that the Lawe Sikap PLTM and the Sepakat PLTMH can become the main electricity supports in Southeast Aceh Regency with a percentage of 50-85%.

Abstract

Synthesis of silica Li4Ti5O12/soda lime composite has been carried out for the anode component of lithium ceramic battery. The Li4Ti5O12 synthesis method is SSR (solid state reaction) from Li2CO3 and TiO2 powders. All lithium-based materials were calcined at 700oC for 2 hours, then ball milled to obtain finer particles and passed to a filter of less than 400 mesh. Before sintering the powder is dissolved in 99% methanol to make a paste. The Li4Ti5O12 paste was sintered at various temperatures from 750oC, 800oC, 850oC, 900oC to 950oC for 2 hours to obtain optimum electrical properties. The phase formed after sintering was identified by XRD.

Abstract

Load imbalance in an electric power distribution system often occurs in the field. This is a single-phase load on different Low Voltage Network subscribers due to the large number of additional electrical loads that do not pay attention to system load imbalances. As a result of this imbalance, a current appears in the neutral of the transformer. The current flowing in the neutral of this transformer causes losses (technical losses/losses), namely losses due to the neutral current in the neutral conductor of the transformer and losses due to neutral current flowing to the ground. By realizing PHB SR (Connecting Equipment for House Connections) it is able to balance the load on the Low Voltage Network on a regular and continuous basis so as to reduce technical losses (losses), simplify the Splicing Field in technical connection of House Connections (SR) on the Pole, improve aesthetics and neatness Network System.

Abstract

An expert system is a computer program tAn expert system can assist a layperson in resolving an issue by making a decision on a problem based on an expert's response. In general, a worker executes his job in an efficient manner that allows him to save money while working. As a result, most employees and entrepreneurs employ tools that assist humans in doing tasks that are simple and time-saving. There are various things that will require processes that are available at the barrier gate, given the performance power that can pick disconnected elements in the machine. The barrier gate system is a parking crossing facility for everyone who will enter and exit the parking lot at the shopping center through automatic crossing gates, where passengers can open the door first, and a parking data checking procedure using the barcode scanner available at the barrier gate is required. In expert systems, the Bayes theorem approach may be used to diagnose barrier gate damage and compute every conceivable symptom that exists in barrier gate damage. The proposed expert system may be utilized to diagnose existing barrier gate deterioration.

Abstract

The State Polytechnic of Tanah Laut is a college located in Tanah Laut Regency, established on September 25, 2009. The college currently offers three majors: Informatics Engineering, Agricultural Industrial Technology, and Automotive Machinery, as well as one study program in Accounting. The current system at The State Polytechnic of Tanah Laut is semi-computerized, with many processes still relying on paper, such as the questionnaires used in the Learning Development Center and Education Quality Assurance Center (P4MP). The P4MP questionnaires are currently filled out using soft files in Microsoft Excel instead of paper sheets, but the process is still difficult for lecturers, students, and education staff and requires a significant amount of time for data recording. To address these issues, an application can be developed to assist in the process of filling out P4MP questionnaires at The State Polytechnic of Tanah Laut. The application will be web-based and designed using ERD (Entity Relationship Diagram), DFD (Data Flow Diagram), Flowchart, and will use the programming languages PHP and MySQL as the database.
